Sisk has completed the €88m Killaloe Bypass, providing a western bypass of Killaloe and an upgrade of the existing R494 regional road. Minister for Transport Darragh O’Brien officially opened the Killaloe Bypass road, a transformative 6.2km development which includes the first new vehicular bridge across the Shannon in more than three decades.
The bridge, known as the Brian Ború Bridge, was a complex engineering feat that took 2.5 years to complete. The project is located in the vicinity of the twin towns of Killaloe, Co Clare and Ballina, Co Tipperary, on opposite sides of the River Shannon.
The scheme will improve the quality of life for residents of both towns. The alternative route will take through traffic and HGVs out of both town centres, thereby significantly reducing congestion, protecting both heritage areas, and providing a much-needed boost to the local economy and the region’s tourism sector.
Steven McGee, Chief Operating Officer (COO), Ireland and the UK, Sisk, said: “Sisk is delighted to have completed this vital new infrastructure improvement project, which is a significant upgrade to the current roads network in both Co Clare and Co Tipperary.
“Connectivity has been enhanced through the construction of the western bypass for Killaloe/Ballina, a new bridge crossing over the River Shannon, and the upgrade of the existing R494 regional road. This project is an excellent example of real collaboration between our client, site team, plus our inhouse engineering services team and key supply chain partners.”
Minister O’Brien said: “I am delighted to officially open this transformative road project, which strengthens the connection between communities in Clare and Tipperary. With approximately €88m in funding allocated by my department, this represents a significant Government investment in regional infrastructure and
underscores our ongoing commitment to investing in and modernising Ireland’s road network.
“Road safety remains a key priority in all our infrastructure projects. The completion of the Killaloe Bypass will significantly enhance safety and efficiency for all road users. The inclusion of dedicated pedestrian and cycling facilities not only improves safety but also encourages more sustainable, active travel along this vital corridor.”
CPAC Modular has broken ground on its cutting-edge €16m manufacturing facility in Dunshaughlin, Co Meath. This major milestone was marked by an official turning of the sod ceremony, led by An Taoiseach Micheál Martin.
The event underscores CPAC Modular’s commitment to innovation, job creation, and industry expansion, strengthening Ireland’s modular construction capabilities.
CPAC Modular’s new facility represents a €16m investment by this family-owned business, which has been operating successfully in Ireland for over 40 years.

John Paul Construction (JPC) and Aggreko have successfully slashed carbon emissions by over 66,000kg and saved 20,357 litres of fuel at a major Galway building site.
JPC, appointed main contractor in early 2024, teamed up with Aggreko for a decentralised energy solution. Instead of a typical large generator for the tower crane and site lighting, Aggreko proposed a hybrid system: a 125 kVA generator paired with a 150/75 kWh battery. This innovative setup allowed for periods of zero-emissions power and adaptability to varying demands.
Aggreko rigorously tested the system in Dublin for two weeks, confirming its effectiveness. Installed in August 2024, the hybrid solution powered the site until February 2025. The generator ran for a maximum of three hours in the morning and evening to boost and recharge the battery.
This resulted in weekly emissions reductions of 2,342 kg and fuel savings of 712 litres, equating to at least €600 in weekly fuel cost savings.
“The construction industry needs to balance power with sustainability,” said Pat Enright of Aggreko Ireland. “Our hybrid battery system allowed JPC to integrate their sustainability values into the Galway project.”
David McKenna, JPC’s Sustainability Manager, highlighted the impact: “Battery energy storage systems, combined with efficient generators for our tower cranes, have been one of the most impactful initiatives for energy and carbon reductions as we work towards our 2040 net-zero goal. Aggreko’s solution was ideal for our Galway project, proving their commitment to our shared sustainability aims.”
The Land Development Agency (LDA) and Horse Racing Ireland (HRI) have reached an agreement on the transfer of land with the potential to deliver 800 homes at Leopardstown Racecourse in south Dublin
Both parties have reached an agreement that will see HRI transfer ownership of circa 17 acres of land to the LDA. The new development will be served by the activation of a new Luas station located on the site.
The two state bodies will work collaboratively and in consultation with Dún Laoghaire-Rathdown County Council on a new masterplan for Leopardstown, which will deliver much-needed affordable housing and protect and further develop the leading racecourse and its extensive racing and non-racing facilities.
The land transfer follows positive engagement between the LDA and HRI to ensure the best outcome for both parties.
Design and planning work on the site-wide masterplan and proposed housing development will commence immediately. Subject to planning, the LDA land will be used to deliver new, A-rated homes, which will be located next to the existing but currently unused Leopardstown Luas stop.
Land at HRI’s campus in Leopardstown was first identified as having the potential for housing in the government’s Housing for All plan.
An Taoiseach, Micheál Martin TD, said: “I am delighted to see these lands being made available to support the delivery of homes at scale, close to critical amenities, in an area of great need. Solving the housing challenge requires collaboration across our society, from government to a range of private and public bodies.”
John Coleman, CEO of the LDA, said: “We are delighted to announce that we have reached an agreement to acquire land at HRI’s Leopardstown campus. Pending planning approval, the site will accommodate over 800 new homes in what is an area of great housing need in Dublin. The agreement follows positive engagement between the LDA and HRI.
“The LDA is now under construction on 16 sites for over 5,000 homes across the country, and we will be adding further new construction starts in the coming months.”
John Coleman, CEO, LDA.

Paul Brown, CEO, Sisk, speaks with ROBBIE COUSINS about a stellar 2024 for Ireland’s leading contractor, dissects the strategic pillars driving the company’s success and unveils ambitious plans for the future.
From geographic expansion to pioneering sustainable practices and fostering a vibrant workplace culture, Sisk is ‘Breaking New Ground’ and setting new benchmarks in the construction industry.
Paul Brown, in his third year as CEO of Sisk, has overseen a massive transformation of the construction giant. He reflects on a stellar 2024, dissecting the strategic pillars driving Sisk’s success, and unveils some of the ambitious plans for the company’s future.
“We have had a very strong year again in 2024,” Paul Brown begins, his voice resonating with a clear sense of achievement. “Revenue increased to €2.7bn.”
This impressive performance, he explains, is a direct result of the maturation of Sisk’s corporate strategy, ‘Breaking New Ground’, which has seen its five key strategic priorities—People & Culture, MMC (Modern Methods of Construction), Digital Transformation, Net Zero, and Quality of Earnings—become deeply
embedded within the business.
“Breaking New Ground, our corporate strategy has now reached maturity, and its five key strategic priorities have been embedded into the business. FY2024 was an improvement on our People & Culture has been our main priority with attrition rates and our Early Careers numbers on the increase.
“Key drivers of this performance have been some notable initiatives and changes across the business. Business optimisation has been key. We have rationalised our business units, making them more userfriendly for our customers.
“Sisk is now seen as an international global contractor. The perception of the business is changing in all geographies. We have an optimised workload in Ireland and the UK, services, healthcare, life sciences and data centres. They have all been lucrative for us and big contributors to our performance as a business.”
Sisk’s international reach is undeniable, with operations spanning across 15 countries. The company’s strategic focus on controlled data centres and life sciences growth, driven by key client relationships and technical opportunities, is a testament to this global ambition.
“We have also recently opened an office in Frankfurt to target life sciences and data centres,” Paul Brown reveals, highlighting the importance of growing their DC/ LS&T presence in Europe, particularly the DACH region. Leveraging global blue-chip relationships, he explains, is central to this
expansion.
Beyond traditional construction, Sisk’s Specialist Services division is also experiencing significant growth. He outlines their objectives: “Sensori Group is actively exploring M&A opportunities in Hard FM providers, Fuse Rail is expanding beyond the rail sector, and Vision Built is investing in specialist engineering and materials.”
2024 has seen Sisk deliver a string of impactful projects, solidifying its reputation for complex and significant infrastructure and commercial developments.
The Dunkettle Interchange Upgrade Scheme in Cork stands out as a prime example. Officially opened in February 2024, this €215m project has been transformative for the region. “Transport Infrastructure Ireland reports that journey times during peak hours have reduced by almost 50% on average,” Paul Brown proudly states. The project’s recognition at the ICE Awards 2025 in the Civil Engineering category is a further testament to its success.
In Dublin, Two-Four Wilton Park showcases Sisk’s prowess in commercial development. This interconnecting office and retail space, completed in 2024, achieved the prestigious LEED Platinum rating. “Strong partnerships drove success on this project,” Brown explains, “leveraging innovative digital strategies to empower subcontractor BIM teams and
enhance their capabilities.” This project, too, was an ICE Awards 2025 winner in the Commercial category.
The momentum continues with several ongoing projects set to shape Ireland’s future. The Limerick Foynes railway line is a significant undertaking, with track laying now complete. “Our team have completed the removal of all original rail line infrastructure, followed by a complete renewal and relaying of 42km of track, sleepers and track bed,” Brown elaborates. The careful restoration and reinstatement of the River Maigue and River Deel bridges underscore the project’s complexity and Sisk’s meticulous approach to the work.
Opera in Limerick is described as a “transformational project,” with the fully developed site capable of employing up to 3,000 people across a 450,000 sq ft campus.
In the healthcare sector, Sisk’s team is making significant progress at Bon Secours Hospital Limerick (BSHS). Anticipated for completion in the summer of 2025, it will treat over 50,000 patients annually.
Further enhancing regional connectivity, the Adare Bypass is being delivered by the Sisk Sorenson Joint Venture, with a government investment of approximately €150m.
In the United Kingdom, Sisk’s UK projects are equally impressive. The Etihad Stadium expansion for Manchester City FC is an “ongoing iconic project,” recently
achieving a topping-out milestone with the club.
In the healthcare sector, Sisk is in the “very early stages” on site of the Children’s Cancer Centre at Great Ormond Street Children’s Hospital.
Paul Brown emphasises the profound responsibility attached to this project: “We’re paying close attention to ensure that we take pride in what we leave behind, and it comes back to our purpose of ‘Creating places for future generations’.”
Looking ahead, Paul Brown outlines a clear strategy for Sisk’s continued growth and impact.
Infrastructure is a key focus. “We are finalising the integration of Ireland Civils and UK Civils into a single business unit,” he announces. “This will enable us to pursue the strategic opportunities that exist in the growing infrastructure sector in both countries and ensure that we are best placed to deliver our projects successfully.”
With significant public sector capital spend anticipated over the next 10-20 years, Sisk is targeting water supply and distribution, wastewater, marine works and flood management.
“We have been a key delivery partner for the Irish government with the National Development Plan 2021-2030 on projects including Dunkettle Interchange and now with the Adare Bypass. We want to continue to support the Irish government,
CPAS
and our infrastructure strategy positions us to do so.”
“We have significant operations in both the UK and Ireland, and we are focussed on further investment in our core sectors. We possess the engineering expertise that enables us to mobilise and support growing investment in Ireland and the UK.”
In Life Sciences and Data Centres, Sisk plans to expand its internal M&E capability via Sensori Group on data centres, alongside the design, manufacture, and assembly of key components.
Innovation is not just a buzzword at Sisk; it’s a fundamental part of its ‘Breaking New Ground’ strategy.
“We have invested heavily in MMC, Digital Transformation and Net Zero to ensure that we stay relevant in 10 years’ time,” Paul Brown asserts. “Our Innovation and Design team, led by Sarah-Jane Pisciotti and Juan Morillas, is instrumental in linking these critical areas. We want to be thought leaders and continue to innovate, but the entire industry needs to innovate to improve the industry as a whole.”
A prime example of this commitment is the successful testing of a new low-carbon technology, developed in partnership with Ecocem and a consortium of partners, to
decarbonise concrete at Sisk’s Wembley Park project site in London. “Initial test results demonstrate over 70% of carbon savings compared to standard concrete,” Brown reveals, explaining that this pioneering project received £500,000 from Innovate UK funding. “Our lowcarbon concrete journey began with the establishment of various strategies aimed at reducing our environmental impact,” he explains, highlighting the creation of an internal low-carbon concrete working group.
“The construction industry has a profound responsibility to reduce our climate impact. As one of the largest contributors to global carbon emissions,” Paul Brown stresses. “The development of low-carbon concrete is a tremendous leap forward in this endeavour. This innovation not only reduces our carbon footprint but also sets a new standard for environmentally responsible construction practices.”
Sisk’s commitment to sustainability extends far beyond the use of innovative materials. In 2024, it achieved an “A” rating for CDP Climate, the highest possible score, reinforcing its commitment to climate action.
“This achievement marks an important milestone in Sisk’s 2030 Sustainability
Roadmap – Building today, Caring for tomorrow,” Brown proudly states, acknowledging the collective effort of their people and supply chain. “This result is an improvement from 2023 when we received an A-,” he adds, underscoring their journey towards becoming a carbon-neutral company by 2030.
Further demonstrating Sisk’s leadership, the company became one of 15 founding members of the Irish Supply Chain Sustainability School in 2024, building on its seven-year membership of the UK School. “The school is now set to provide free industry-supported training, knowledge sharing and support for best practices in sustainability within the Irish built environment,” Brown explains, urging Irish supply chain partners to leverage this invaluable resource. “The school is about the collaboration of the entire industry to play our role in tackling the climate emergency.”
Addressing the perennial challenge of skills shortages, Sisk is taking proactive steps to attract and retain talent.
“Sisk wants to become as attractable as possible as an employer to unlocking future talent,” Paul Brown affirms. We recently promoted Bernie McGarrity as Chief People Officer, and in Q3 2025, we will have more of a focus on how we target school leavers and how we can attract people from diverse backgrounds and industries, including working mothers, back to work.
“We have over 350 people in early careers programmes at Sisk, including apprenticeships and graduate programmes,” he notes. While acknowledging that 19.5% females currently work at Sisk, Brown states, “We are challenging ourselves to attract more females into the sector.” The power of community is fostered through Employee Resource Groups (ERGs) covering LGBTQ+, neurodiversity, gender balance, and cultural diversity.
Sisk’s commitment to fostering future talent is evident in its main sponsorship of Ireland Skills Live in 2024, which attracted over 30,000 second-level students. Furthermore, a new website and TikTok channel have been developed to directly target a younger generation and encourage careers in construction.
Inclusivity is deeply ingrained in Sisk’s culture, as evidenced by its ‘Inclusion and Belonging Compass’ and its accreditation as one of only 23 organisations in Ireland with ‘Investors in Diversity Gold’ status.
Paul Brown highlights the significance of this accolade, recognising the team’s commitment to embedding Diversity and Inclusion (D&I). Retaining its ‘Investors in People - Platinum status’ further validates
the progress made across its People & Culture strategy.
In a sector often associated with highpressure environments, Sisk is taking a pioneering stance on mental wellbeing.
“Established on World Mental Health Day in 2024, our Mental Health Peer Support Programme is a key part of our commitment to creating a workplace where mental health is supported,” Paul Brown explains. Inspired by his predecessor, former Sisk CEO Steve Bowcott, this programme provides a network of trained colleagues offering a listening ear and signposting support.
Sisk’s dedicated Occupational Health & Wellbeing team, comprising experts in counselling and psychotherapy, exercise science, and physiotherapy, underscores its proactive approach. “These are roles that would never have been traditionally associated with the construction industry,” he acknowledges. “But as a business, we know we need to do something practical to help combat the mental health crisis that our sector faces.”
With over 70 trained mental health peer supporters across the UK and Ireland, the programme’s tagline, ‘Peer to Peer, Shoulder to Shoulder’, encapsulates its core ethos of visibility and accessibility.
Paul Brown describes the move to the new Sisk HQ in Citywest Business Campus as “the single most positive step in my time as CEO”. He emphasises the transformative impact: “We have created a new, improved culture. The general integration has been brilliant; it’s a great facility, and people want to come to work in an engaging space. It’s all about improvements, which have led to better productivity.
“The new office has invigorated the workforce, bringing a new dynamism reflected in staff behaviours. Initiatives like a Citywest running group and on-site gym have enhanced health promotion opportunities. Staff are mingling more in
our open plan canteen, and ultimately, it is bringing people together,” Brown observes, acknowledging the challenges of fostering in-person connection in the modern workplace.
The office move also coincided with a major brand refresh, visually representing Sisk’s evolution. “We now believe that this visually represents our modern business as we are not just a general contractor, but construction specialists across a whole host of services and sectors.”
Early engagement with clients, particularly repeat customers, is crucial for Sisk’s adoption of MMC technologies and integration.
“Circular Economy principles are at the heart of what we do,” Paul Brown states, highlighting the integration of smart lean design solutions, low-carbon material choices, MEP envelope performance optimisation, and the integration of structural, architectural, and MMC into design through early engagement.
Brown adds that Sisk’s ‘Two-Four Wilton Park’ project in Dublin 2 exemplifies its digital prowess, with extensive upskilling provided to subcontractor BIM teams.
“The use of 4D planning and drone operations for ‘Planning versus Actual’ construction delivery is also highlighted. “During pre-construction, we utilised 4D Construction Sequencing as an aid
for digital rehearsals for our approach to project delivery, which gave the client, IPUT, great confidence in our delivery,” he explains”. This collaborative approach, with bi-weekly workshops and programme updates, ensured meticulous planning and execution.”
Paul Brown acknowledges the broader industry challenges, particularly “uncertainties around tariffs” which he believes risk a “state of paralysis.” He calls for collective action: “We need to turn this into a positive collectively as a sector because we all have similar challenges.”
“In addition, we work in close collaboration with Construct Innovate, Enterprise Ireland, IBEC, MMC Ireland, and CIF underscores our commitment to driving industry-wide improvement.”
Paul Brown’s insights paint a picture of a dynamic and forward-thinking company. Sisk’s strong 2024 performance, driven by strategic focus, global expansion, and a relentless pursuit of innovation and sustainability, positions it as a true leader in the construction industry. With a clear vision for the next two years and a deep commitment to its people, Sisk is not just building structures; it is working to build a better future for the industry, the people who work in it and the generations to come.

Group Managing Director and co-owner of Designer Group
Paul Nicholls is very pleased with the performance of the leading M&E contractor in 2024. It was a year when Designer Group consolidated its business and pursued targeted growth in key sectors.
Paul Nicholls comments: “We have been on a strong upward curve for several years, so last year was about strengthening our foundations, making sure we had the right systems, structures, and people in place to take the business forward. We have focused on the timely delivery of our projects and improving our overall efficiency, which in turn leads to better value for our clients, but also increased profitability to help fund further investment and growth in the business.”
He continues, “We’ve invested significantly in our team. We’ve brought in experienced people across key functions who are attracted by our culture and our plans for the business. We’ve also developed our internal teams, empowering them to take on more responsibility. That’s probably what I’m most proud of — seeing talented people step up and grow within the business.”
Designer Group also stayed focused on its core sectors — data centres, energy, and life sciences. “That clarity has helped us
strengthen our delivery, stay aligned with our long-term goals, and put the business in a strong position for the next phase of growth.”
Designer Group is active in 10 markets across three continents. Some are long-term operations, while others are more projectspecific; however, Paul Nicholls explains that all align with the contractor’s overall strategy to support clients in high-growth and high-impact sectors.
“Sector-wise, our core strengths lie in data centres, energy, life sciences and building services. Over the past few years, we’ve expanded significantly in the energy sector, particularly in decarbonisation and infrastructure. We’ve supported multinational clients with complex carbon reduction initiatives, including biomass and heat pump technology alongside on-site power generation.
“We are also involved in critical infrastructure projects like the Celtic Interconnector, which will link the electricity grids of Ireland and France for the first time.
“Projects like these are not just technically demanding; they align with our purpose as a company and our commitment to supporting
volume — we focus on sectors where we can add real value and
According to Paul Nicolls, Designer Group’s outlook for the coming
“The opportunities are there, but we recognise that the landscape is changing fast — whether that’s in terms of economic uncertainty,
“We’re not in the business of growing for the sake of it. We’ll adapt to these challenges, and we’ll continue to invest in our teams, double down on the sectors we know, and build the kind of client relationships that stand the test of time.
“Our European operations, particularly in energy and data centres, will be a big focus. And we’ll keep pushing the bar internally in terms of how we plan, deliver and support our projects.”
Over the past year, Designer Group has been focused on pursuing initiatives that support its long-term vision for sustainable growth and diversification.
Paul Nicholls explains, “Decarbonisation has been a key focus, and we’ve led several projects to reduce emissions, including transitioning industrial clients to heat pumps or biomass and integrating renewable energy systems for clients in the data centre, life sciences, and food & beverage sectors.
“Our data centre business has also expanded. During 2024, we completed five significant data centre projects across three campuses in the Nordics for a key client. We are also working on other data centre projects across central and southern Europe at present.
“We know that the strength of our team is key to delivering on our ambitions. Over the past year, we’ve continued to grow our team internationally while also investing in homegrown talent, ensuring that we have the right people in place to drive our success forward.
Sustainability is integral to every aspect of Designer Group’s operations and projects. From net-zero carbon facilities to NZEB buildings and BREEAM and LEED certifications, every project now incorporates sustainable elements, ensuring it delivers long-term value for its clients.
Paul Nicholls explains how the company has gone about setting and achieving goals, “We are leading in decarbonisation, renewable energy, and power generation, including initiatives like energy solutions for data centre clients in Ireland and overseas.
“Internally, we’ve set ambitious targets, including achieving zero waste to landfill by 2026 and net zero by 2035. With significant investments already made to date, we have strategic carbon reduction projects in planning. We are implementing a new ESG online platform that will support both our ESG strategy and CSRD requirements.”
These sustainability commitments influence Designer Group’s project scope and business operations, ensuring it not only meets the evolving demands of the industry but also contributes to a sustainable future.
He adds, “Sustainability is now a core driver of how we do business and how we support our clients.”
Paul Nicholls understands that addressing skills shortages is key to Designer Group’s long-term success. This is why the contractor puts a big emphasis on building strong relationships with schools and colleges.
He explains, “Through apprenticeships, graduate programmes, and mentoring, we are creating clear pathways for young people to enter and grow within our industry. We want to ensure the next generation is equipped with the skills, experience, and confidence to thrive.
“But we don’t just look outward — we also actively invest in our people. There are numerous routes for progression within Designer Group, and we make a point of identifying and nurturing internal talent. We have seen our people grow their careers in real and inspiring ways: from site-based roles into professional services and from administrative positions into technical teams. These journeys reflect our commitment to nurturing talent from within and building a culture where growth is encouraged, supported, and recognised. There is a real culture of learning in the business, mostly driven by our award-winning training facility, where we are constantly training and upskilling our workforce to ensure we are at the cutting edge of technology and innovation.”
On the diversity and equality front, Paul Nicholls adds that Designer Group is committed to building a more inclusive workforce. “We’re actively encouraging more women to consider construction as a career. As a company, we know our business is at its strongest when everyone feels valued and supported. It’s not about meeting quotas — it’s about fostering an environment where people from all backgrounds can succeed and contribute fully.”
Paul Nicolls understands that life can be tough and that construction is a particularly challenging field to work in.
“Within society generally, mental health often takes a back seat. But we’re committed to changing that. Designer Group employees have access to a range of platforms, services and supports. Our DG Benefits Portal provides a huge amount of self-directional and interactive content and a “Live Well” blog providing health advice and guidance on a range of topics, such as the importance of physical exercise, stress and anxiety management. This is a preventative approach and has proven popular with our team members.”
He adds: “We also have confidential 24/7 EAP support and mental health case management via Spectrum Live, which is available to staff and their family members. This service has multiple access points, such as a freephone and WhatsApp, and operates to clinical standards. The service can help to address issues such as financial planning and debt management, which sometimes is a root cause of deteriorating mental health.
“We have trained our own in-house Mental Health First Aiders for that more immediate and often preventative approach to supporting colleagues on site.
“Additionally, we’re proud to support the Lighthouse Charity, which offers well-being support specifically for the construction industry. They provide a vital service, helping to break the stigma around mental health and offering a lifeline to those who need it.”
He continues, “At Designer Group, we very much understand the importance of psychological safety and the importance of a positive, supportive and respectful organisational culture, which sets clear expectations for all.”
Paul Nicholls adds his voice to many people in the industry who believe data centre development is being unnecessarily hindered, resulting in huge consequences for the Irish economy. He believes that the lack of energy infrastructure is an issue that needs to be addressed urgently.
“There are some major challenges around data centre delivery in Ireland, and unfortunately, all the large tech companies are already making decisions to invest large sums in other European countries. While delays in the planning system have certainly slowed progress and are not acceptable, the delivery of infrastructure, particularly energy, is where the real issue lies.
“Ireland’s grid is under real strain, and we need a more strategic, sustainable approach to energy planning. At Designer Group, we’re already responding to this by supporting clients to take control of their own energy needs. On several of our current projects, we’re delivering on-site power generation solutions for data centre companies, reducing reliance on the grid and increasing resilience. This kind of integrated thinking, where power, sustainability, and infrastructure delivery go hand-in-hand, is essential for Ireland to remain competitive in the global data economy. Unfortunately, as a country, time is not on our side. If the government does not act quickly and decisively, we will continue to lose this essential and critical investment, with far-reaching consequences for future economic growth.”
Discussing Designer Group’s approach to working with clients, Paul Nicholls explains, “In an ideal world, neither the contractor or client should ever have to rely on the contract. When people are referring to the contract, it’s usually too late. At Designer Group, we look to operate in a much more collaborative way with our clients.
“Having said that, I do feel that there is room for improvement in how contracts are structured. The current models don’t always reflect the complexities of modern M&E projects. A more flexible and collaborative approach to contracts would help minimise risks and foster better working relationships between clients and contractors. The more we can focus on partnership and collaboration, the better the results will be.”
At Designer Group, technology and innovation are at the core of its operations. Paul Nicholls explains the company is always striving for the next innovation or the next piece of technology that it can use to become more efficient.
“We have fully embraced a digital way of construction, and now, with the onset of AI, the opportunities are even greater. This not only boosts efficiency but also allows for better communication and collaboration across the board. Working closely with clients and subcontractors, we’re making sure everyone’s on the same page from day one, helping us to deliver projects on time and within budget while reducing waste and rework. The results speak for themselves, and we’re excited to see where this digital journey takes us.”
Paul Nicholls sees the overriding concern for the industry over the next 18 months as global economic uncertainty. Uncertainty, for instance, around tariffs, is causing a lot of concern within the industry, particularly in the life sciences and data centre sectors.”
He adds, “As a country, we need to make large investments in our infrastructure. Our power, water and waste grids are not where they need to be. We also need to invest further in renewable power. If we are courageous enough to make these investments now, we can help insulate our economy and our industry from the challenges posed by the current global economic uncertainty,” Paul Nicholls concludes.
From Irish roots to European M&E powerhouse, Micheál O’Connor, Group Managing Director, Dornan Engineering, speaks with ROBBIE COUSINS about a most successful 2024 that was topped off with the M&E firm’s acquisition by an ideal partner to fuel its next phase of growth.
Dornan Engineering Group, a name synonymous with excellence in mechanical, electrical, and HVAC engineering, has witnessed an extraordinary period of growth. Established nearly six decades ago, the company has transformed into a leading force across Europe, boasting a turnover of €734m in 2024 and entering 2025 with a backlog of €1.6bn. Micheál O’Connor, Group Managing Director at Dornan Engineering, sheds light on the factors behind this success, the strategic acquisition by Turner Construction Company, and the evolving landscape of the construction industry.
Dornan’s impressive revenue surge, from €365m in 2021 to a projected €1.2bn this year, is substantially attributable to a booming European data centre sector.
Micheál O’Connor explains that clients in this rapidly evolving field have increasingly requested Dornan to transition into a General Contractor (GC) role.
“Data centres is a rapidly growing sector,” he explains. “Clients and their requirements are still evolving, and they are also looking to evolve their delivery strategy.”
This has led to the adoption of a GC1 and GC2 strategy, where GC1 handles site works, infrastructure, shell and core, whereas GC2 focuses on fitting out the data centre.
“We have been asked now to fulfil a GC2 role on a number of data centres, and we are successfully doing so,” he affirms.
This expanded scope has significantly boosted revenue and presented new challenges, necessitating a substantial increase in Dornan’s workforce from 1,000 at the start of 2024 to approximately 1,450 at this time.
“While clients are asking us to grow our involvement with them, Dornan remains firmly rooted in its mechanical and electrical (M&E) foundation.” Micheál O’Connor clarifies, “Dornan is not trying to be all things to all people. We don’t see ourselves rebranding as a general contractor. The GC strategy is aimed at leveraging new opportunities through existing expertise while continuing to serve
Micheál O’Connor, Group Managing Director, Dornan Engineering.
The 2024 acquisition of Dornan by Turner Construction Company, finalised in January 2025, has been pivotal. Micheál O’Connor describes the timing as impeccable, paraphrasing the famous beer commercial line, “If Carlsberg did acquisitions…”.
“In terms of the cultural fit of the company, in terms of speaking the same language, having the same attitude towards business, and being a problem-solving company, being a people-centric company, Turner’s and our values around safety and quality, and respect for people are so well aligned,” he enthuses.
Given its rapid growth, this strategic alignment comes at a crucial time for Dornan. The acquisition provides Dornan with valuable support and opens new avenues through Turner’s existing client relationships in Europe. Furthermore, Turner’s affiliation with its larger parent company, ACS Group, a global infrastructure operator with revenues of circa €42bn in 2024, presents significant synergies and a unique offering across the
“Irish companies have done enormously well in mission-critical and advanced facilities sectors across Europe, underpinned by transferrable skillsets derived from the country’s long-established life sciences sector”
group of companies, particularly in the data centre development sector. He says this will lead to Dornan establishing a base in Spain, where ACS is headquartered in Madrid.
Despite the international expansion and new opportunities, Micheál O’Connor acknowledges a mixed outlook for Dornan in the Irish market.
“The outlook in general in Ireland is mixed. The Irish market is pretty tight at the moment and very competitive. There’s largely an embargo on data centres because of the energy issue, and certainly, life
sciences is not where it was a number of years ago.”
In contrast, Europe remains Dornan’s primary growth engine, and the UK has emerged as a strong market. “The UK government’s decision to classify data centres as critical infrastructure has created a welcoming environment for investment, significantly boosting our UK revenues.”
Countries like Ireland have benefited greatly from having a life sciences sector in situ over the past decades because the skillsets developed through serving these life sciences clients have provided companies such as Dornan with experience and skillsets not found in many other locations.
Micheál O’Connor comments, “Irish companies have done enormously well in mission-critical and advanced facilities sectors across Europe, underpinned by transferrable skillsets derived from the country’s long-established life sciences sector.
“Ireland has had a strong record down through the years of attracting clients into the country. But I think other countries are becoming more competitive and more attractive. Continental Europe and the UK are now a far bigger market for Dornan than Ireland. This year, we will probably do
less than 10% of our business in Ireland.”
A critical challenge he sees facing the construction and engineering industry, particularly in Ireland, is a significant skills shortage. Micheál O’Connor highlights Dornan’s reliance on talent from Eastern Europe, the Philippines, and South Africa. He also expresses concern about the lack of Irish people entering supervisory and construction manager roles, attributing it to insufficient throughput at the apprentice level.
Dornan is actively combating this by promoting diversity and inclusion. Its ‘Women@Dornan’ network is a key initiative that he says is working really well.
“We’ve created strong career paths for women within the company, and I believe this, as well as other interventions, is helping attract more women.”
This work also extends to working with schools and colleges to promote STEM subjects and encourage interest in trades. “We are seeing more young women enter the trades, and we’re delighted about that,” he shares.
Micheál O’Connor stresses the need for a greater national effort to encourage more young people into trades, highlighting
the excellent career prospects. “It’s no exaggeration to say that the career that some of our craftspeople can have is equivalent to their professional counterparts,” he asserts.
Sustainability has moved to the centre of Dornan’s operations in the past few years. A dedicated team and working groups are focused on setting ambitious targets, collecting data, and embedding sustainability into all aspects of the business.
Beyond Dornan’s internal efforts, Micheál O’Connor advocates for broader changes within the industry and the country. He believes the Irish construction industry, particularly in the FDI sector, boasts a world-class skillset in designing and constructing mission-critical facilities, a fact often overlooked domestically. He urges greater investment in this talent pool.
But, he highlights two pressing societal and economic challenges to national growth: Ireland’s housing shortage and infrastructure gap.
“The availability of affordable housing for the workforce supporting growing industries, and the benefit of more modern and efficient infrastructure would support, sustain and attract future investment,” he notes.
He suggests strategic investment in transport links, pointing to the lack of a motorway between Cork and Limerick and the underutilisation of Shannon Airport as opportunities for transformative impact.
“We have a real chance to unlock the full potential of regions like the Midwest and South by investing in integrated transport networks. When I travel in the rest of Europe, I rely heavily on rail because of its reliability and convenience. That’s the kind of infrastructure that can elevate Ireland’s competitiveness and quality of life - and it’s within reach.”
As Dornan Engineering continues its impressive trajectory, Micheál O’Connor’s insights reveal a company adept at navigating unprecedented growth and evolving industry demands. Its strategic partnership with Turner Construction and a sharp focus on talent development, inclusion, and sustainability position it strongly for continued success across Europe.
However, his candid assessment of the challenges facing the Irish market serves as a crucial reminder of the importance of addressing fundamental issues in housing and infrastructure to ensure Ireland remains a competitive destination for international investment.
Kingspan has introduced its groundbreaking PowerPanel system, the first factoryintegrated insulated solar photovoltaic (PV) solution to achieve the rigorous FM 4478 certification. This innovative system combines the superior thermal performance of Kingspan’s QuadCore insulated panels with high-efficiency PV technology into a single, precisely engineered unit.
Robert Guilmartin, General Manager of Kingspan - Solar Energy Solutions, emphasises the significance of this development: “The new PowerPanel system offers building owners, the option to install a complete, certified, integrated solar and roofing solution, significantly reducing onsite labour and assembly.”
A key achievement for PowerPanel is the FM 4478 certification, a demanding standard that specifies stringent approval criteria for rigid PV modules integrated with a roof assembly. To earn this certification, the PowerPanel successfully endured severe tests, including fire exposure from above the structural deck, simulated wind uplift, hail damage, and resistance to gravity loads.
“Kingspan PowerPanel is the first factory
applied system designed for pitched roofing systems to achieve the FM4478 certification globally,” Guilmartin highlighted. The certification includes ongoing factory audits of material suppliers, providing building owners with the assurance that the tested product is consistently manufactured and sold.
The PowerPanel system is built around Kingspan’s proven QuadCore insulated roof panel, which can achieve exceptionally low U-values down to 0.11 W/m²K and an air leakage rate of 3 m³/hr/m² or less at 50Pa. This ensures a highly thermally efficient and airtight building envelope, now enhanced with the capability to generate renewable energy through factoryinstalled PV modules.
Kingspan collaborated with Longi Solar, a global leader in cell and solar module manufacturing, to develop the solar pv module, using their high efficiency back contact solar cells. The system incorporates rear ventilation for the solar modules,
ensuring optimal cooling and enhanced performance. The solar modules can be removed and replaced if there is ever a need to do so.
Guilmartin highlighted Kingspan’s extensive 15 plus years’ experience in solar PV as crucial to the PowerPanel’s development. “To create the product, we partnered with Longi Solar, combining our experience in insulated roofing solutions, with Longi Solar’s expertise in solar module manufacturing, has enabled us to produce a panel equipped with a solar module that integrates the latest solar technology and our advanced Quadcore technology for enhanced efficiency and performance.
The PowerPanel solar PV system is mounted on the insulated panel under controlled conditions using state-of-theart robotics in a factory accredited to ISO 9001 and ISO 37301. This provides a very high level of quality control and helps to eliminate the risk of poor installation of the PV modules on site.
Guilmartin emphasises “Often, solar mounting systems are overlooked because
they are seen as a low-value component in the system design. However, if they have not been subject to compatibility testing and designed and/or installed incorrectly, it can lead to additional costs, health and safety risks, and unnecessary nuisance issues for the building owner, all of which can be avoided at the initial design stage.”
He continues, “Members of Kingspan’s Field Service team have unfortunately attended several sites subject to poor solar PV installation practices, some damaging the building envelope and leading to business disruption for the building owner. With PowerPanel, this risk is removed.
“From a procurement perspective, the reassurance of dealing with a single manufacturer, where major components of the system are fully traceable, is a significant benefit – something that’s often lacking in the standard PV procurement process. Furthermore, the product has already completed standard building regulation testing, meeting EN standards.”
During construction, health & safety risks are considerably reduced due to reduced time spent working at height, and the system promotes the use of mechanical lifting devices, lessening manual handling. The accelerated speed of roof construction and PV system activation enables building owners to achieve a return on investment more quickly.
Kingspan offers a single, comprehensive, insurance-backed warranty covering the solar module, mounting, insulated roof panel, and coating for up to 25 years.
Robert Guilmartin reiterates the critical importance of the FM 4478 certification, emphasising the rigorous testing the PowerPanel underwent to achieve it. “This gives the building owner, a significant level of assurance that the product has been fully assembled in controlled factory conditions and rigorously tested by a leading global body.”
PowerPanel is suitable for new buildings
and renovation projects, particularly those with tight build schedules and a need to minimise on-site disruption. Moving the mounting and solar module installation process to a factory setting accelerates on-site programmes and enhances quality control.
Generally speaking, Robert Guilmartin points out that rooftop solar PV can contribute up to 25% of a buildings annual energy consumption, or in some cases higher if the roof space is large and electrical demand is low, making it a significant factor in reducing carbon emissions and energy costs.
“Building owners who want to reduce their operating energy costs can improve the thermal efficiency of their building and generate energy with this single system,” explains Guilmartin. “Developers and landlords can benefit from extended warranty periods and enjoy the peace of mind that comes from having a certified system. And naturally, all end customers can benefit from the reassurance of the third-party insurer testing, which has been completed specifically to the FM Approvals standard 4478.”
Guilmartin believes that commercial and industrial rooftops have a vital role in decarbonisation strategies. “Utilising these rooftops for solar deployment is a more sustainable approach than using
up greenfield sites,” he comments. “The PowerPanel is well-suited for various applications, including pharmaceutical facilities, schools, retail and distribution, and many public buildings, where solar PV can contribute significantly to reducing energy consumption and carbon emissions.
“Overall, we believe the PowerPanel offers a compelling solution for a sustainable future in Irish construction and sustainable property management.”
The design of the solar PV modules and the associated balance of system components follows traditional system design principles.
However, Kingspan recommends that installers working with PowerPanel familiarise themselves with proper installation techniques through companyprovided training. Kingspan’s Field Service and Technical Support teams also offer project-based training to address unique design or site requirements.
Kingspan has also launched Power Konnect, a service connecting customers with recommended specialist contractors for project design and construction support.
The Kingspan Solar Energy Solutions team provides expert design and technical support throughout projects, addressing aspects like maintenance access and shading avoidance.
Initially, PowerPanel will be launched in Ireland, the UK, and the Benelux markets, with the first project on site in Ireland in July. Guilmartin anticipates steady demand for highly efficient buildings coupled with tested and certified solar PV systems to reduce operational costs and carbon emissions in the coming years. He affirms Kingspan’s commitment to the continuous development of new products and services to meet evolving customer needs. “We will continue to evolve our products and services to meet our customers’ current and future needs, always looking to anticipate what those might be,” Robert Guilmartin concludes.

BAM Ireland is driving forward with a strong 2024 performance and ambitious plans for 2025 and beyond. BAM UK & Ireland Executive Director Alasdair Henderson speaks with ROBBIE COUSINS about the contractor’s strategic shift towards value-creating projects, a deep commitment to sustainability and efficiency through innovation, and a proactive approach to nurturing its workforce.
BBAM Ireland has been a cornerstone in the Irish construction landscape for over six decades, shaping the nation’s built environment. Alasdair Henderson, Executive Director of BAM UK & Ireland, offers insights into the company’s performance in 2024 and its ambitious outlook for 2025 and beyond. He discusses BAM’s strategic transformation, commitment to sustainability and the broader challenges and opportunities facing the Irish construction sector. He also provides some insight into what it means for BAM employees to be involved in the delivery of the new National Children’s Hospital.
2024 was a “Very good year for BAM in Ireland, financially and economically,” according to Alasdair Henderson. This success was not accidental, but the culmination of a three-year transformation journey focused on strategic clarity and value creation.
“We’ve been on a transformation journey for the past three years since I came to Ireland, and that has been very clearly about focus for the business,” Henderson explains. “This involved a deep dive into our product market combinations (PMCs), identifying the specific customer groups and tailoring offerings to create genuinely compelling value propositions.
“Price leadership in this industry is not a good strategy,” he asserts, emphasising that it leads to low margins and instability.
BAM’s strategy has shifted towards building longer-term relationships with fewer customers who “regard those assets for more than just their capital value. This means working with clients, whether public or private sector, who will utilise the assets to generate their own revenue and income.”
He continues, “These are the customers that value the thing that
BAM can bring to them, which is high quality, absolutely the ability to build at any scale and any level of compliance, particularly at the top end of complexity and scale, and deliver cost-effective assets that make their businesses work.”
While revenue in 2024 experienced a deliberate decline – a direct consequence of shedding high-volume, low-margin projects – profitability consistently improved. “We had a very solid profitability performance in 2024,” Henderson confirms.
Looking ahead, Alasdair Henderson anticipates significant growth in 2025, projecting an increase of 25% to 40%. “The journey of engaging with customers and identifying the kind of work that we should be doing and bidding for it means that in 2025, we will see growth, and growth that is profitable. And that’s how 2025 is looking for us now.”
However, he acknowledges broader industry concerns. “The concern for the industry as a whole is about how long it’s taking customers to procure and the lack of confidence or the disruption to confidence. Customers are delaying some capital spending decisions, with the result that some revenues will shift to future years. That’s something that’s a concern across the industry.”
External factors, such as inflation (experienced in 2022) and potential tariffs in 2025, also influence customer behaviour and capital commitments. These can cause project start dates to shift, impacting revenue profiles across the industry. However, he also believes that the Irish government’s slow rollout of infrastructure and the ongoing housing crisis are as significant, if not more than global issues in deterring customers from making spending decisions.
THESE CHALLENGES, HE SEES A “SPLIT MARKET” EMERGING.
“Sectors such as energy and data, often self-funding and capitalrich, are continuing to show high confidence and investment, particularly in areas like wind energy.
“Increasingly, government spending on infrastructure will be a key driver as European governments grapple with ageing infrastructure and growing population demands.”
Royal BAM Group’s commitment to both societal and shareholder value is evident in its 2024 performance, boasting impressive earnings before interest, taxes, depreciation, and amortisation (EBITDA) of €303m, strong liquidity, and a robust order book.
The company’s leadership in sustainability is further underscored by its receipt of a prestigious CDP Climate A rating for the sixth consecutive year.
Alasdair Henderson is very positive for BAM in Ireland for the coming three years. He comments, “The company secured an excellent order book throughout 2023 and 2024, providing a strong foundation for growth in 2025, 2026, and 2027. From a BAM standpoint, we’re very well positioned.”
While global instabilities, such as the war in Ukraine and the Middle East, pose potential inflationary risks and may divert government spending, BAM’s strong order backlog and high level of market opportunities position it well.
“Order intake for us in 2024 was excellent, and we’ve secured that springboard that we have been building over the past couple of years to take us forward.”
BAM aspires to be “The most sustainable contractor,” a goal rooted in both market demand and moral conviction. “There’s an understanding that you can’t continue to build infrastructure and buildings in the way we’ve always done. Construction needs to contribute to the fabric of society rather than draw from it,” he comments.
“Innovation at BAM is heavily focused on improving sustainability. This includes hydrogen fuelling and electrification, whereby we are investing in research for hydrogen fuelling of plant and working to reduce liquid fuel usage on our sites and premises. A significant step has been the switch to certified Hydrotreated Vegetable Oil (HVO) in Ireland, which reduced CO2 emissions by approximately 80% overnight. The ultimate goal is to eliminate liquid fuels entirely through electrification and alternative fuels.
“We are utilising flywheel units for tower cranes to manage peak energy demand, significantly reducing overall energy consumption.
“We have also mandated the use of hybrid generators with battery packs across our business, which not only reduces liquid fuel usage but is also proving to be more cost-effective. In addition,
sense.”
Alasdair Henderson explains that BAM has been researching alternatives to concrete for ground use for several years, including bio-calcification and driving efficiency in material usage.
“At project level, we are aiming to minimise the amount of dig and dump. For example, at our Greystones School Project on the Department of Education Schools Bundle Lot 6A, rather than excavating the material on the site, we used an in-situ lime treatment, with the result that we also reduced multiple truck movements and spoil disposal elsewhere.”
He adds, “Sustainability and innovation for a business like ours rewards technical detail and the effort put into understanding every impact of the area you’re innovating in. As a result, while cutting emissions, we will also be reducing many costs.”
BAM recognises that its success is intrinsically linked to its people. In 2024, the company significantly enhanced its ‘Employee Value Proposition (EVP)’, introducing private healthcare, additional holidays, and robust family-friendly policies beyond the usual standard maternity and paternity leave. These include fostering cover and even grandparent leave for significant family events.
“This EVP change in 2024 was received really well in the business, and it has helped us make sure that our offering is really attractive.”
The company is also further expanding its traineeship and apprenticeship programmes in 2025, recognising the need for diverse talent.
“We have a growing business. We need more people in our business, and there are multiple routes to attracting them.” Beyond traditional disciplines, BAM welcomes individuals with STEM backgrounds that are not necessarily linked to construction, offering the necessary training to adapt and thrive in construction.
“We have apprentices and graduates from traditional construction disciplines such as civil engineering and quantity surveying. But there are also routes into our business for people from any STEM background. For example, if you’re a geologist, mathematician or physicist, we can give you the skills you need to work in construction and build a career. The same applies to other
non-cognate graduates who have the right aptitude and ability to learn. We want to bring these people into our business as early as possible and help them grow their careers.”
Alasdair Henderson sees the health, safety and mental wellbeing of all BAM employees as being tantamount to the company’s continued success. While acknowledging that the industry has traditionally been cost-driven, he firmly states, “When it comes to safety, environment, sustainability and quality, we can’t sacrifice those to cost. Every time you try to take a shortcut in any of these places, it ends up costing more. For me, safety is not a priority but a prerequisite.”
His personal commitment is evident in his monthly safety tours, where he engages with employees on site to understand their feelings and concerns about safety and to give them the assurance he’s got their back.
“The simple act of telling people that you care and listen to what they have to say about their concerns creates a situation whereby they can take pride in what they do and always feel empowered to speak up if something feels wrong.”
Henderson also addresses the challenge of drug use in society impacting the industry, advocating for more advanced and comprehensive drug and alcohol policies, including preemployment testing, random testing, with-cause testing and postincident testing to ensure a safe working environment for all.
“When a person is at work, they have a right to be sure that nobody around them is in a condition that might cause them harm. As an employer in a high-hazard, well-managed risk environment, which we are, it is right that a comprehensive drugs and alcohol policy be implemented. For instance, anybody who is operating safety-critical equipment should be undergoing routine drug and alcohol testing. And to take this one step further, every member of the team, including myself, should understand and accept that random drug and alcohol testing is an essential tool in ensuring the safety of everyone on site.”
Modern methods of construction (MMC) and digital transformation are intrinsically linked at BAM, enabling a “production mindset” that transforms artisan construction into a more assembly-line process. The company’s school bundles, utilising precast elements manufactured off site and assembled quickly on site, exemplify this approach.
“Digital models are crucial for this efficiency, allowing for 4D planning and precise component integration. The National Children’s Hospital project, for instance, has leveraged modularisation of services with digital modelling, ensuring high confidence in the fit and effective delivery of mechanical, electrical, and building services. Mercury and Jones Engineering, for example, have been exceptional in the application of these technologies on the project.”
BAM is also exploring digital twins, creating models that understand building performance using real-time data streams. Furthermore, digital advancements are enhancing BCAR compliance, particularly in complex large buildings, for validating and verifying build quality for regulators and customers.
Despite negative media and political focus, the National Children’s Hospital is hailed by Henderson as “an extraordinary building” and “the most impressive building that Ireland has built in the public sector space.”
With major elements complete and commissioning well underway, BAM anticipates facilitating early access for the end user and handing over the project very soon.
“It is extraordinary to see that this will be the most amazing environment for the healing of children, not just in Ireland but in the world. We have groups of US- and European-based doctors coming to visit the hospital, walking around it and wondering why they’re not getting that level of facility. It is a world-class building, and it’s going to serve Ireland for 100 years.”
Henderson expresses immense pride in the BAM teams who delivered the project amidst the challenging media and political scrutiny.
While not overly concerned by the global economic situation, Alasdair Henderson is “very conscious of global impacts on Irish construction.” Foreign Direct Investment (FDI) clients have slowed their investment, he believes, to a great degree influenced by local issues such as housing, infrastructure, and planning.
He emphasises that housing delivery is part of a larger system. “There is absolutely no point in talking about housing until you have solved water, wastewater, power and transport issues.” He advocates for a greater shift towards public transport to support housing development in areas with existing infrastructure capacity.
His concerns for the industry include addressing planning once and for all. “The inconsistency and unpredictability of the planning process remain a significant challenge.”
In the area of funding and procurement, he says there is a need for professionalisation in procurement and a move away from the Public Works Contract towards more effective forms of contracts.
Finally, and most significantly, he is at a loss to understand the perceptions of the construction industry in Ireland.
“There is a completely nonsensical narrative in political and media circles that Irish contractors are somehow unreliable, expensive or unable to manage large projects. Irish contractors are doing fantastic work in every country across Europe. This negative perception domestically makes it harder for decision-makers to commit to major projects and can drive FDI businesses away from Ireland.
“The thing that concerns me is this popular belief that somehow contractors are unreliable or that we are expensive or the construction in Ireland somehow is not done effectively, when the reality is absolutely the opposite of what is being said,” Alasdair Henderson concludes, underscoring the critical need to change the narrative and acknowledge the vital role of the construction industry in building Ireland’s future.

Ireland faces an unprecedented convergence of housing, economic, and environmental crises. MARION JAMMET, Head of Policy & Advocacy, Irish Green Building Council, writes about a single, innovative approach that could offer a powerful pathway to tackle these complex challenges, foster new business opportunities and build a more resilient future.
Ireland is grappling with a multi-faceted crisis. The housing crisis is relentless.
The Central Bank states we need 52,000 new homes annually just to keep pace. According to the CSO, nearly 70% of 25-year-olds are still living with their parents, with over 80% citing crippling living costs as the main reason. Add to this the looming threat of US tariffs, which could stifle the international supply chains vital to our island nation.
These interconnected economic and social pressures do not exist in isolation— they are unfolding against the backdrop of wider global emergencies. Last year was the hottest on record, surpassing the critical 1.5 °C warming threshold. Wildlife populations have plummeted by 69% since 1970, signalling a biodiversity collapse. Meanwhile, according to the World Health Organisation, air pollution claims seven million lives prematurely each year.
What if there were a single, powerful tool to address these interconnected national and global challenges while also unlocking new business opportunities?
While not a magic bullet, ‘Circularity’ offers a unique approach to tackle a vast array of problems. In the building industry, circularity means shifting from a wasteful ‘take-make-waste’ model to a closed-loop system. This involves a strong emphasis on waste prevention, reuse, smart design, resource efficiency, and innovative circular business models.
The European Parliament’s definition from 2023 states: “The Circular Economy (CE) is a model of production and consumption, which involves sharing, leasing, reusing, repairing, refurbishing and recycling existing materials and products as long as possible. In this way, the life cycle of products is extended.”
How can circularity be our gamechanger? For example, maximising the use of vacant and underutilised buildings could deliver new homes more quickly than traditional construction, leveraging existing infrastructure. Crucially, a typical residential retrofit produces just onequarter of the carbon emissions of a new build.
Combatting ecological impact can be addressed by utilising existing structures and specifying construction products made
from secondary materials. By doing this, we significantly reduce the “embodied ecological impact” of construction – the off-site biodiversity damage from extracting and processing raw materials.
We could boost Irish industry and resilience by developing new, biobased, low-carbon construction products from Irish crops, such as straw, hemp, and other agricultural byproducts. This will reduce our reliance on imports and strengthen us against volatile supply chains. This also fosters new, sustainable rural industries and cuts carbon emissions simultaneously.
So, how do we make this a reality?
At the Irish Green Building Council’s recent Build Green Now Conference we unveiled ‘Building A Circular Ireland’ –our roadmap for a resource-efficient built environment. It is built on four core priority actions:
1. Value Existing Buildings: Prioritise reducing vacancy and dereliction, revitalising our communities, and preserving the economic, social, and cultural value of existing structures.
2. Plan for Resource Efficiency: Integrate robust guidance within the planning system to create resource-efficient and circular neighbourhoods. Design for evolving needs, optimise housing occupancy, and champion compact growth and the sharing economy.
3. Design for Circularity: Embed circular principles into every stage of building design. Develop benchmarks for lean resource efficiency and waste reduction, and design buildings with adaptability and eventual deconstruction in mind.
4. Close the Materials Loop: Foster new markets for biobased construction materials from Irish agriculture. Design and operate products and buildings in accordance with the “Waste Hierarchy” principles, prioritising prevention, reuse, recycling, and recovery before disposal.
The Building a Circular Ireland roadmap promotes a sharing economy and circular business models like Extended Producer Responsibility and product-as-a-service. Achieving these goals requires agile systems for planning, regulation, and certification that foster innovation and ensure safety. Public procurement will be key to this transformation.

Ireland’s construction sector gears up for mandatory auto-enrolment pensions in 2026, CPAS clarifies the landscape for employers, highlighting the benefits of existing industry schemes like CWPS and CERS and outlining key considerations for securing their workers’ financial future.
Ireland’s construction sector is a vital pillar in Ireland’s economy and plays an essential role in shaping infrastructure and meeting our housing needs. As the industry continues to expand, the issue of pensions for workers has gained increasing attention, particularly with government plans to introduce Auto-enrolment pensions in January 2026.
The construction sector is building the country’s future. In CPAS, our goal is to help those construction employees enjoy financial security when they retire and protect them should they experience ill health or die while working. Since the Government first legislated for Autoenrolment in 2024, we have been working hard to communicate the benefits of proper pension planning to both the members of our pension schemes CWPS and CERS and to all employers in the sector.
This article answers some of the questions
we get asked as we continue to engage with employers and employees.
One of Ireland’s largest industry-specific occupational pension schemes, CWPS has been providing pensions for the construction sector and related industries since 1965. CWPS ensures workers have access to pension savings, along with ancillary benefits such as sick pay and life assurance. The transient nature of the construction workforce is always a challenge for pension coverage. Under CWPS, a member’s pension account moves with the employee if they change employer. This principle is known as “pot follows member” and will be incorporated into the Government’s new Auto-enrolment system. CWPS have operated this way for 60 years.
Like CWPS, CERS is also an industry wide multi-employer occupational pension scheme. While CWPS generally offers fixed benefits in a “one size fits all” approach, CERS in contrast offers bespoke pension, life cover and income protection benefits for the sector. Employers can design a benefits package with CERS that will attract and retain key staff. Enhanced pension schemes foster long-term commitment among employees and can contribute to workforce stability.
WHICH IS BETTER - AUTOENROLMENT OR CWPS AND CERS?
Auto-enrolment (AE) is a fundamentally different type of pension arrangement to CWPS and CERS, which are both Occupational Pension Schemes. For people working who do not currently have a pension, AE is preferable to reaching retirement age with only the State pension to live on. However, there are distinct advantages for occupational pension schemes such as CWPS and CERS over AE; in particular around tax relief, AVCs, early retirement and ancillary benefits such as life assurance and sick pay.
REPLACE MY CURRENT CWPS OR CERS PENSION SCHEME?
No. Auto-enrolment was set up to provide pensions for Irish workers who have not yet made provision for retirement savings. Employees who are members of CWPS or CERS, will not be brought into the Autoenrolment scheme.
THAT ARE NOT IN CWPS OR CERS?
The simple answer would be to put them in CWPS or CERS, but this is not as straightforward as you would imagine. Not many contracts of employment include a provision that makes membership of your company pension scheme mandatory. For workers in the sector covered by Sectoral Employment Orders (SEO), then membership of CWPS is mandatory for specified workers as required under the agreement for the sector. However, you may have employees not covered by the SEO.
You have offered them membership of your company pension scheme, but they have opted not to join. What next? The following is a summary of your choices:
• Open your existing plan to all employees on an opt-in basis. This requires spending the next few months engaging with employees to persuade them that this is the best option. CPAS can help our CWPS and CERS clients with this communication task.
• Set up a new category under your existing plan but with AE matching rates and offer on an opt-in basis. Again, this requires good communication to
get employees to opt in.
• Open existing plan to all with employer-only contributions and encourage individual contributions.
• Do nothing new and AE will pick up your non-pensioned employees.
• Some mixture of the above.
These are just some of the questions we get asked. As you can see, discussions can become extensive, and we recommend that employers establish an Action Plan to help meet their pension goals in time for the introduction of Auto-enrolment in January 2026.
It is important for the Construction Sector to invest in the welfare of its workforce to strengthen its foundation for growth and meet the demands of a growing economy. Investing in people is key to sustainable growth and a stable and secure workforce leads to higher productivity, better project outcomes, and overall improvement in industry standards. CPAS recognises the role of employers in promoting pensions to the workforce and we are happy to talk to you about the best way we can help you achieve better outcomes for your workers at retirement. We can help you design suitable pension schemes and benefit packages, and we can communicate the value of this to your employees through written, online and in person communication.

Our passion can be seen in every construction detail, every material choice, every ISO certified quality process, every safe working day, and in every smile by the students and staff of Ireland’s first permanant, modular-built, school for Lucan East ETNS. Co. Dublin.
In an industry often constrained by tradition, CPAC Modular is boldly reshaping the landscape of construction across Ireland. With over four decades of heritage behind it, the Dunshaughlin-based company is leading a new era of modular construction, defined not just by speed but by smart technology, sustainability, and purpose.
Sean Murphy, Managing Director, CPAC Modular, says, “We’ve always believed that innovation in construction must be driven not only by necessity, but by purpose.”
That belief has guided the company through a transformative innovation drive, marked by investments in people, new technologies, and materials. The result?
A growing reputation as a national leader in Modern Methods of Construction (MMC)—and now, a global contender.
In April, CPAC Modular made headlines with the completion of Ireland’s first permanent modular-built school. Delivered on time and within budget, the project opened its doors to 500 students, embodying the durability and design potential for offsite construction. “It reminded us just how important our work is and why we do what we do,” Murphy reflects.
But CPAC Modular is not stopping there. The company is pioneering a new era of “smart modular” building, integrating predictive maintenance systems into its modular solutions. “Across the operational life of the building, our Built Smarter offering will alert us to potential maintenance issues before they become problems,” Murphy explains. It’s a gamechanger for facility management—and just one example of how CPAC Modular is transforming modular from a method into a movement.
At the heart of CPAC Modular’s journey is a commitment to people and place. The company employs 110 staff and prides itself on being a family-owned enterprise where values matter. That ethos is enshrined in its motto: “Part of the Pac.”
And now, the company is laying the foundation—literally—for its next chapter. A new €16 million state-of-theart production facility in Dunshaughlin, County Meath, is officially underway following a sod turning event with An
Taoiseach Micheál Martin earlier this month. Spanning 22 acres, the purposebuilt HQ will triple CPAC Modular’s capacity, positioning it to help meet the infrastructure needs of the country across multiple sectors, including education, healthcare, commercial, and residential sectors, including housing, apartments, and purpose-built student accommodation (PBSA).
“This facility is not just an investment in infrastructure,” Murphy says. “It’s an investment in people.” Over the next five years, CPAC Modular plans to create 100 new jobs across engineering, design, manufacturing, and project management — strengthening both the company’s capabilities and the regional economy.
While speed and scale matter, sustainability remains at the forefront of CPAC Modular’s ethos. The company has embraced lean manufacturing and wastereduction practices to ensure its production is as environmentally responsible as it is efficient. “We manufacture our buildings in a quality-controlled environment which greatly improves our efficiency and dramatically reduces waste” says Murphy.
It’s this fusion of green thinking and technical precision that’s earning CPAC Modular national recognition.
CPAC Modular is also tackling a key barrier to the wider adoption of modular construction: perception. Through its award-winning Built Smarter CPD initiative, the company invited architects, specifiers, peers and clients onto the live construction site
of Ireland’s first permanent modular school before the project was completed. There, attendees experienced the method’s benefits firsthand—upending outdated misconceptions and gaining further support for permanent modular construction.
With eyes firmly set on the future, Murphy believes that CPAC Modular is ready to bring Irish-built innovation to international markets. “Our new facility allows us to explore scalable and immediate solutions across housing, student accommodation, and public infrastructure. It’s a demonstration of our commitment to what modern construction can—and should—be.”
As CPAC Modular breaks ground on its new headquarters, it’s also breaking ground on a reimagined future for construction—one that’s smarter, faster, and more sustainable by design.

ROBBIE COUSINS, Editor,
Irish Construction News, introduces the Irish Construction News ‘Top 40 Building Contractors 2024’ and explains how the list was compiled.
The Irish construction industry demonstrated remarkable growth and resilience in 2024, as highlighted by the release of the ‘Irish Construction News’ Top 40 Building Contractors 2025’ list. This annual snapshot reveals a vibrant sector driven by strong domestic and international demand.
Robbie Cousins, Editor of Irish Construction News, introduces this year’s definitive ranking, compiled by Foundation Media Ltd. The list provides an insightful overview of the general building contractors shaping Ireland’s built environment and showcasing Irish expertise on the global stage.
Ireland’s leading 40 building contractors achieved a combined turnover of €12.9bn in 2024, marking a significant increase of €2.2bn from the €10.7bn reported in 2023. This figure underscores the industry’s robust performance. Of this total, €7.7bn in construction activity was generated within Ireland, while a substantial €5.2bn came from exported services, demonstrating the sector’s international reach and competitive edge. The entry threshold for the Top 40 list also increased, rising to just over €37m from €32m in the previous year, indicating a higher level of financial strength among the leading firms.
This continued success in both domestic and international markets is crucial for attracting foreign direct investment (FDI) to Ireland and solidifying the country’s reputation for excellence in construction worldwide.
Employment within the Irish construction sector continued its upward trajectory in 2024. According to the Central Statistics Office, direct employment reached 176,000 people by the end of Q4 2024, an increase of 14,700 from 161,300 in Q4 2023. The gender split within this workforce remained largely consistent, with 158,000 males and 18,000 females, representing an 89.7% male
to 10.3% female ratio. The construction sector accounted for 6.3% of the 2.78 million people employed in Ireland at the end of 2024.
This growth in employment signals a healthy and expanding sector, although challenges related to skilled labour shortages persist.
Beyond the impressive figures of the Top 40, several key trends defined the Irish construction landscape in 2024.
While construction activity across many European countries faced a contraction in 2024, Ireland bucked the trend. Total Irish construction output was forecasted to grow by 3.9%, making it the highest in the Euroconstruct area. This resilience is attributed to a strong domestic economy and increased investment.
While inflation for construction materials showed signs of moderating towards the end of 2023 and into 2024, the cost of labour continued to be a significant upward pressure on pricing across all sub-sectors. Access to skilled labour remained a top challenge for the industry.
The industry continued its embrace of technological advancements, with increased adoption of Building Information Modelling (BIM) and other digital tools to enhance efficiency and productivity, modern methods of construction (MMC), particularly 2D systems like timber frame.
Sustainability and green construction have gained increasing prominence. Projects focused on reducing carbon footprints, enhancing biodiversity, and implementing renewable energy systems were on the rise, driven by both industry commitment and anticipated stricter regulatory efficiency standards from the revised Energy Performance of Buildings Directive.
The planning and regulatory environment remained a significant barrier, often leading to longer and more expensive project delivery times. Reforms to the planning system were seen as crucial for accelerating housing and infrastructure development.
METHODOLOGY BEHIND THE RANKINGS
Foundation Media Ltd, the publisher of ‘Irish Construction News’ and ‘constructionnews. ie’, annually compiles the ‘Top 40 Building Contractors’ list. Companies are ranked based on their overall turnover, which includes both Irish and international revenue, for their most recent trading year. Turnover figures are directly sourced from the contractors themselves.
For inclusion, companies must have their primary business operations based in the Republic of Ireland. Direct contact is made with contractors to request turnover figures for their business year ending on 31 December 2024 or the closest available year-end. All submitted figures must relate to Irish-based building contractors or Irishbased subsidiaries of foreign-based building contractors and include turnover from direct overseas trade by Irish subsidiaries. To ensure accuracy, all returns are validated by a company director or accompanied by an auditor’s letter and are meticulously checked and verified by the editor of Irish Construction News.

KEY ACTIVITIES: Main Contractor
The sense of momentum around John Paul Construction is discernible to people throughout the industry, and Managing Director Liam Kenny puts it down to a simple ethos, “If you’re not moving forward, pushing to see how you can improve, then you are standing still.”
The business achieved an overall revenue in 2024 of €736m, with the majority achieved in the Irish market. The Irishowned company remains committed to its current strategy of sectoral and geographical diversification as Liam expands, “There is a very real sense of opportunity in the UK and mainland Europe with the data centre and life sciences sectors showing great potential in particular. Currently, we are working on major projects in both the UK and Germany and are optimistic that we can build on our experience.”
This strategy is reflected in John Paul Construction’s current Irish workload, which includes major life sciences projects in Longford and Galway. The company is working for repeat client Hibernia REG on the Harcourt Square development and is also undertaking landmark residential projects in Woodbrook, Donore and Castleborbes.
From an infrastructure perspective, it is nearing completion of works at Rosslare Europort, a complex project involving multiple stakeholders and a variety of requirements, all while keeping the port fully operational. The organisation has also just commenced restoration works at Bank of Ireland’s College Green. Finally, in the data centre sector, the business is working on a range of high-profile projects both locally
and abroad.
Like its peers, John Paul Construction is cognisant of the current global market uncertainty that abounds but has been keen to focus on the areas it can control. Its recent Supply Chain Summit saw over 400 delegates representing 290 companies meet at The Curragh where a keynote address was presented by Minister Jack Chambers TD outlining the government’s priorities in generating momentum in housing and critical infrastructure. While Jim Gavin, COO of the Irish Aviation
Authority, but more widely known for his GAA exploits, provided a fascinating talk on leading cultural excellence. These talks complemented the content shared by the leadership team on safety, quality and engaging with the supply chain. The event underlined the importance of collaboration between John Paul Construction and its partners.
John Paul Construction remains committed to its core values in working with its clients as Liam Kenny explains, “We believe in excellence, respect and teamwork. Our business strategy may evolve, our ambitions may change, but, fundamentally, those core values will remain in place. From an operational perspective, everything starts and ends with safety. From there on in it’s a case of asking ourselves, Are we doing everything possible to ensure that our clients receive a consistently strong experience in working with us?
“If we can maintain those principles, then we have a good chance of further success.” Liam Kenny concludes.

KEY ACTIVITIES: Main Contractor
Founded in 1925, PJ Hegarty marks its centenary in 2025, a significant milestone that reflects a century of delivering excellence across Ireland and the UK. This significant milestone highlights not only the company’s legacy of delivering high-quality projects but also its evolution into one of the most progressive and trusted building and civil engineering contractors in the region. Remaining family-owned throughout its history, PJ Hegarty has successfully maintained its founding values while continuously adapting to the changing needs of clients, technology, and society, operating from offices in Dublin, Cork, Limerick, Birmingham, and London.
The company employs over 500 skilled professionals, reflecting its capability to manage multiple large-scale ventures simultaneously, supported by its sound financial and management principles. Its portfolio spans various sectors, including pharmaceutical, commercial, high-tech, life sciences, hyper-scale data centres, retail, tourism, institutional buildings, refurbishment, and civil engineering projects. This versatility is backed by PJ Hegarty’s adeptness in various construction methodologies, including management contracting, design and build, alliance/partnering, PPP contracts, and traditional building arrangements.
In 2024, PJ Hegarty delivered several landmark projects. These include Block N1 at Central Park, a 19,270 sq metre LEED Goldcertified commercial building in Dublin, shortlisted for the 2025 ICE Awards; the Kilkenny Cheese facility, one of Europe’s most efficient continental cheese plants; the Echo Romeo Rapid Exit Taxiway project at London Gatwick; and the Midleton Distillery Experience, winner of Tourism & Hospitality Project of the Year at the Irish Construction Industry Awards. Significant completions include West Pharma Building 3 (Phase 1), a confidential pharmaceutical development in Limerick, and multiple key facilities for Irish Distillers at Midleton. In Cork, PJ Hegarty also completed a 5,100 sq metre GMP warehouse for Gilead, featuring cold storage, cleanrooms, high-bay racking, and significant infrastructure upgrades.
Ongoing work in 2025 includes several high-profile projects: the Waterfront South Central project in Dublin, set to be the new European headquarters for Citibank, the Google Treasury
redevelopment, Gatwick Airport’s Pier 6, and the expansion of a blue-chip client campus in Cork.
In line with its enduring values, PJ Hegarty continues to place safety, sustainability, and social responsibility at the heart of operations. Throughout 2024, the company worked tirelessly to achieve a Gold Diversity Award from the Irish Centre for Diversity and achieved this in early 2025, becoming one of only 28 organisations in Ireland to achieve the distinction. With an inclusion score of 88.8%, PJ Hegarty outperformed national and industry averages, reflecting its long-term commitment to fairness, respect, equality, diversity, inclusion, and engagement (FREDIE).
The company was again recognised for safety excellence, receiving Higher Distinction and Consistent High Achiever Awards from NISO. Community and ESG-led initiatives remain a core focus, including its main sponsorship of the 2025 Ronald McDonald House Charities Plane Pull, support for Barretstown’s Amazing Race, Lighthouse Club site visits, biodiversity partnerships with the Men’s Shed, and DEI webinars for its supply chain partners.
As PJ Hegarty celebrates 100 years of delivering outstanding projects across Ireland and the UK, it remains committed to safe, sustainable, and high-quality construction built on the foundation of its people, values, and future-focused mindset. The company looks forward to what the second century of PJ Hegarty will hold for the organisation and the industry.

In 2024, Glanua made two strategic acquisitions that have significantly strengthened its service offering and market position in the UK. The addition of Aqua Operations in July enhanced Glanua’s operations and maintenance capabilities, particularly in the UK industrial market, where Aqua’s expertise supports the delivery of end-to-end water and wastewater solutions for clients across key sectors.

In 2024, Clancy Construction delivered exceptional performance, marked by robust financial results, major project milestones, and commitments to community and sustainability – all in line with its “Built on Partnership” ethos. The company achieved a turnover of €141,420,501, reflecting strong client demand and effective project delivery across Ireland. This financial strength was underpinned by the successful delivery of flagship projects and a continued focus on operational excellence.
Clancy completed several high-profile projects across Ireland, showcasing its multi-sector expertise in healthcare, residential development, and beyond. Notably, the company delivered a stateof-the-art Intensive Care Unit at Tallaght University Hospital – an achievement honoured internally as Clancy’s Project of the Year. This critical facility significantly expanded the hospital’s intensive care capacity, exemplifying Clancy’s proficiency in delivering complex healthcare projects.
In Cork, Clancy delivered “Carraig View” in Blackrock, a development comprising 30 modern apartments for Cork City Council. This project is now providing much-needed housing for the community, managed by the Tuath Housing Association. This development demonstrated Clancy’s ability to collaborate with local authorities to deliver sustainable homes. Together, these flagship endeavours reinforced Clancy’s reputation for quality, safety and partnership-driven delivery.
Clancy remained deeply committed to corporate social responsibility (CSR)
throughout 2024, giving back through charitable donations and volunteer initiatives. Through its annual Christmas Charity Initiative, Clancy donated €22,500 to five Irish charities, supporting causes from dementia care and cancer research to youth empowerment and homelessness. One highlight was a €5,000 donation to the Little Blue Heroes Foundation, presented during a visit to Clancy’s Tipperary office to support the foundation’s work with children.
Additionally, the firm supported the next generation of construction professionals by sponsoring the annual Clancy Award at South East Technological University (SETU), which in 2024 recognised an exemplary student’s performance in construction management. These efforts strengthened community ties and amplified Clancy’s social impact beyond its construction sites.
Progress in sustainability was another cornerstone of Clancy’s year. Guided by a sustainability strategy aligned with the United Nations Sustainable Development Goals (SDGs), the firm implemented initiatives to reduce its environmental footprint. Measures included data-driven energy tracking on projects, hybrid power generators cutting on-site diesel use by 80%, installing solar panels and a biomass boiler to increase renewable energy usage and expanding the electric vehicle fleet. These efforts improved operational efficiency while underscoring Clancy’s commitment to a greener future. Clancy also introduced monthly energy performance tracking to ensure continuous improvement in sustainability. In recognition of its
sustainable practices, Clancy won the Energy Efficiency Initiative Award at the 2025 Business & Finance ESG Awards, reinforcing sustainability as a core company value.
Clancy’s excellence and leadership were further affirmed by industry recognition in 2024. In September, the company was named one of Ireland’s Best Managed Companies for the tenth consecutive year—a distinction reflecting its consistent superior performance and strategic vision.
This Deloitte-led programme recognised 129 indigenous companies across Ireland in 2024, and Clancy’s inclusion highlights its standout management and governance. Such honours underscore the firm’s resilience in a competitive sector and its reputation for excellence.
As 2024 concluded, Clancy Construction’s standing was stronger than ever, bolstered by a blend of financial success, project excellence, social responsibility and innovation in sustainability. These achievements have positioned the company for continued growth, firmly reinforcing its status as a trusted construction partner and responsible corporate citizen dedicated to delivering value to clients, communities across Ireland, and the environment.

ROBBIE COUSINS, Editor, Irish Construction News, introduces the ‘Irish Construction News Top 20 Mechanical & Electrical Engineering Contractors 2025’ and explains how the list was compiled.
Ihe ‘Irish Construction News Top 20 Mechanical & Electrical Engineering Contractors 2025’, offers a comprehensive snapshot of the vibrant Irish Mechanical and Electrical (M&E) sector as it stood at the close of 2024. The year was nothing short of exceptional, demonstrating the profound impact and expanding global footprint of Irish M&E and process engineering firms.
A defining characteristic of 2024 for Irish M&E contractors was their continued robust performance on the international stage. A growing portion of revenue was generated from overseas projects, a testament to the strong and enduring relationships cultivated with foreign direct investment (FDI) clients operating in Ireland. These vital partnerships have consistently led to Irish expertise being sought out across Europe and beyond, solidifying their reputation as global leaders.
The industry’s success is deeply rooted in its unparalleled insights and capabilities within highly specialised sectors. Irish M&E contractors have delivered impressive results in critical areas such as data centres, life sciences, and pharmaceuticals, showcasing their precision, efficiency and deep understanding of complex project requirements.
Beyond their project delivery prowess, Irish M&E contractors have consistently remained at the vanguard of innovation and sustainability. Their commitment to setting new industry benchmarks is evident in substantial investments in cutting-edge off-site fabrication facilities. This strategic move enhances project efficiency, reduces waste, and improves safety. Furthermore, these firms are deeply committed to nurturing talent, evident in their comprehensive in-house career and personal development programmes designed to maximise their teams’ potential.
The financial performance of Ireland’s Top 20 M&E Contractors in 2024 underscores the sector’s robust health and growth trajectory. Collectively, these leading firms achieved an impressive combined turnover of €6.54bn in 2024, marking a substantial €790m increase from their overall turnover of €5.75bn in 2023.
A closer look at the revenue streams reveals an interesting shift: Domestic activities contributed €2.94bn in 2024, a decrease from €3bn in 2023. But exported services saw a significant surge, generating €3.6bn in 2024, up from €2.75bn in 2023. This highlights the increasing reliance on international markets for growth.
The benchmark for inclusion in this prestigious Top 20 list also rose considerably, with the entry point for 2024 being €31.1m, a
notable jump from €22m in the previous year, reflecting the overall growth and increased scale within the sector.
The ‘Irish Construction News Top 20 Mechanical and Electrical Engineering Contractors Listing 2025’ is meticulously compiled by Foundation Media Ltd, the publisher of Irish Construction News and ‘constructionnews.ie’. The ranking is based on each contractor’s overall turnover figure (combining Irish and international revenue) for their most recent trading year, with a focus on business years ending closest to 31 December, 2024.
Only companies with their primary business based in the Republic of Ireland are considered. Turnover figures are directly sourced from the contractors themselves and must relate to Irish-based building contractors or Irish-based subsidiaries of foreign companies, including direct overseas trade. Crucially, all submitted figures are subject to stringent verification, requiring validation by a company director or an accompanying auditor’s letter, and are further checked by the editor of Irish Construction News to ensure accuracy and integrity.
In conclusion, 2024 was a landmark year for the Irish M&E contracting industry, characterised by significant financial growth, global expansion driven by specialised expertise, and a steadfast commitment to innovation and sustainability.

Jones Engineering, a global leader in mechanical, electrical, process, and fire protection services, marked a year of major milestones and innovation in 2024. With over 4,200 employees and active projects in 19 countries, the company continues to deliver high-impact results across Ireland, the UK, Europe, and the Middle East. In 2024, Jones Engineering achieved several remarkable project successes across the life sciences and renewable energy sectors. Among the standout achievements was the company’s continued leadership in off-site modular delivery, highlighted by the successful design, transport, and integration of fully assembled cooling modules and packaged plant rooms across multiple countries, including Belgium, Finland, Denmark, and the Netherlands. This approach not only accelerated project timelines but also significantly reduced onsite risks and environmental impact.
The company made further strides in the renewable energy space, becoming increasingly active in wind farm infrastructure and associated grid delivery projects. These developments support the global transition to green energy and reflect Jones Engineering’s strategic focus on sustainability-driven growth. Their contributions in this sector underscore their capability to manage complex infrastructure demands while aligning with environmental priorities. At the forefront of Life Sciences, Jones Engineering proudly supports some of the world’s leading pharmaceutical and biotechnology companies in delivering cutting-edge manufacturing and laboratory facilities. Across Ireland and Europe, our teams are driving progress on major Bio-Pharma projects where precision, compliance, and world-class expertise set the standard.
International growth remained a core strategic pillar throughout the year. The company’s footprint expanded further into Europe and the Middle East, driven by long-term client relationships and early contractor involvement that fosters speed, quality, and scalable delivery. These strategic expansions are setting the stage for sustained global impact and long-term resilience. Sustainability also took centre stage. In 2024, Jones Engineering reaffirmed its commitment to reducing absolute Scope 1 and 2 GHG emissions by 50.4% by 2032, compared to a 2022 base year.

It is this dedication to developing and supporting people that saw it maintain its ‘We Invest in People – Platinum’ and achieve ‘We Invest in Wellbeing – Gold’. These accreditations place Kirby among the top two per cent of organisations worldwide to work for.
Kirby marked a major milestone in November 2024 with the official opening of its new €8m off-site manufacturing (OSM) facility at Junction 17 National Enterprise Park in Portlaoise, Co Laois. This state-of-the-art facility is designed to enhance the company’s

In addition to OSM services, the new building hosts a dedicated apprentice training facility, which will allow for classroom-based and practical education.
Kirby is committed to being part of the local communities where it has a presence, whether that’s in Ireland, the UK, mainland Europe, or South Africa. This was demonstrated earlier this year, when the company was unveiled as the main sponsor for camogie in County Galway in a five-year deal. CEO Henry McCann says: “We’ve been working in Galway since 1997 and have witnessed the incredible growth and success of the camogie squads across the county. The hard work and dedication on display across the county is truly inspirational and aligns so well with how Kirby strives to deliver for our clients, so this partnership is the perfect fit for our team.”

MSL Engineering Ltd is a full-service mechanical engineering contractor operating across a wide range of industry sectors. With over 45 years of expertise and a flexible project management approach, MSL delivers best-in-class projects utilising BIM and modular fabrication processes to the highest standards of workmanship, safety, quality, and reliability.
Founded in 1979, MSL Engineering specialises in the fabrication and installation of process, utility, and high-purity pipework, platforms, steelwork, and equipment installation across many industry sectors.
Modular fabrication and assemblies
Fabrication and installation of process, utility, and high-purity pipework
Managing multi-discipline subcontractors including HVAC, scaffold, craneage, insulation, painting, and NDT
Utilising BIM and 3D modelling design processes
With a workforce of over 700 people, MSL has grown to become one of the leading players in an industry that has seen parallel growth in the pharmaceutical, biopharma, semiconductor, chemical, oil and gas, energy, data centre, and food & beverage sectors.
Originally established to provide craft support to the fledgling but now defunct NET plant in Marino Point, Cork, the business expanded its client base over time and developed a reputation for reliability, engineering excellence, and the ability to get the job done.
Retaining the roots of the original founders, the company is a wholly owned Irish entity. It has organically evolved from providing support services to local industry to a position where it now competes successfully for large-scale engineering projects and
provides a full range of engineering and constructability solutions to clients throughout Ireland, the UK, Europe, and the US.
Safety Commitment: Working in inherently hazardous industries, MSL has always taken an uncompromising approach to safety. This is evident in its high standards and longstanding safety record, its ISO45001-accredited safety management system, and its behavioural safety-based systems of work.
MSL’s desire to continuously improve to stay ahead of the competitive curve has led it to identify and invest in new business processes in recent years. As a result, the company significantly increased turnover and expanded its area of operation to include Denmark, Belgium, the Netherlands, Switzerland, Sweden, and the UK.
Digital Technologies Investment: The company’s investment in digital technologies means MSL continuously improves its BIM offering to clients and its digital project delivery (DPD) capabilities. MSL also encourages and promotes early contractor engagement and an integrated project delivery (IPD) approach by offering modular design and modular construction experience to maximise off-site manufacturing and fabrication (OSM) opportunities for clients.
Recently, MSL has successfully demonstrated its ability to execute an “OSM Integrator” role on significant CAPEX projects of scale, by coordinating between client, designer, and contractor, and capitalising on any potential value added by OSM and a modular approach.
Reflecting strong growth, MSL has invested in a modern 140,000 sq foot fabrication facility in Ringaskiddy, Co Cork. This new facility, adjacent to the newly relocated Port Of Cork, includes a large-scale modular fabrication workshop, a piping fabrication workshop, and an 8,000 sq. foot clean piping workshop. It enables MSL to continue to service all their existing clients and allows them to expand and develop relationships with new clients in Ireland and abroad.
MSL Managing Director Brian McGrath says: “Our mission is to set the industry standards for safety, quality, and reliability, consistently exceeding client expectations. Guided by honesty, respect, and integrity, we are dedicated to forging enduring partnerships that deliver mutual benefit and success for our clients, team, and community.
“Our focus in developing a standard of performance is to ensure all MSL personnel are empowered to achieve their full potential and are recognised for doing so. Our performance standard defines how well each function or task must be performed in order to meet or exceed expectations, thus ensuring our standards are best in class.”
With continued growth, a new modern Fabrication Facility, ISO accredited Management Systems in Safety (ISO45001), Quality (ISO9001) & Environmental (ISO18001), and investment in new innovative business processes, MSL Engineering Ltd continues to challenge itself to deliver the highest standard of service deserved and expected by its clients.

Lynskey Engineering Ltd is a mechanical contractor operating for 60 years. Historically, the firm carried out projects in the commercial, educational and healthcare areas in Ireland. Over 15 years ago, it began working in mainland Europe, initially in Germany, on commercial projects. At about the same time, it completed its first data centre project for an American multinational firm in Dublin.
2010 marked the start of a change in focus for the company. Since then, it has worked almost exclusively in the private sector, with a growing percentage of its business overseas and in the technology space.
Following Covid, Lynskey found that the office development sector is much quieter. Projects were scarce and consequently extremely competitive. Data centre construction has been extremely busy for the past five years in Ireland and overseas. However, the extent of data centre work in Ireland will reduce due to planning difficulties and power constraints in the electrical grid.
In recent years, overseas projects have accounted for between 25% and 50% of Lynskey’s turnover. The larger jobs have been concentrated in Germany, but it has also worked in Poland, the Netherlands, France, Italy and the Czech Republic. More recently, projects tend to be larger in scope and scale, but the quantity is lower.
Although croup turnover for 2024 at just under €60m was less than in 2023, growth prospects are still very positive, particularly in mainland Europe and the UK.
Lynskey Engineering sees the main avenue for company growth over the next few years will come from overseas. It has developed considerable expertise in data centre construction, and it has received requests from main contractors and clients to tender for work in Scandinavia, the UK and Europe. It will look to establish a greater presence in these countries to facilitate its expansion into those regions.
