DRI Q3 2025

CARRYING THE TORCH

Since its launch 26 years ago, Demolition & Recycling International (D&RI) has been at the forefront when showcasing the very best in our industry.

Along the way, it has benefitted from outstanding editorial leadership (names like Paul Marsden, Steve Ducker and Lindsay Gale come readily to mind).

I am honoured to be the latest custodian of the Editor’s chair, though it comes with a touch of sadness as we bid farewell to my predecessor, Leila Steed.

Her work earned deep respect both within KHL and across the industry, and I know many of you will join me in wishing her every success in the future.

By way of introduction, I have been with KHL for nearly five years, working across all titles, including D&RI, as Content Editor.

More recently, I spent two years as Editor of our sister publication International Rental News. Together, those roles gave me a strong grounding in the industry, and before stepping into this post, Leila also offered me further valuable insights.

She summed up the demolition community in one word: family. She was right. Even in these first few weeks, I’ve seen how collaboration and mutual support define the sector, and I look forward to continuing that tradition with you.

Of course, this comes at an exciting moment, with preparations well underway for the World Demolition Summit in Nashville.

I’m looking forward to seeing many of you there and hearing your perspectives on the challenges and opportunities ahead.

The event also gives us the chance to celebrate all that is good in the industry through the World Demolition Awards. The shortlist for that is now set, and I can't wait to come together to celebrate in November.

For those I’ve not yet met, please feel free to reach out at lewis.tyler@khl.com. I’d be glad to hear from you.

Warm regards, LEWIS TYLER D&Ri Editor

DEMAREC tools proves every day that good tools are literally and figuratively speaking more than half the battle.

In fact, in the end the correct piece of equipment determines the success and outcome of each job.

Therefore, DEMAREC advises its contacts to focus on the piece of equipment and not on the machine, never the other way around!

Thus, it is never ever necessary to surrender any capacity and as a result any (business) performance and profits. In other words, an investment in a DEMAREC tool is much more than a sound investment that is guaranteed to repay itself 100%!

High Reach Demolition Machines

The performance of a concrete or scrap shear is especially important when mounted on a high reach demolition machine.

For this type of machine, the maximum tool weight is defined by the manufacturer. That’s why the 20–25% performance increase offered by DEMAREC’s PremiumLine demolition tools — thanks to the DemaPower system — will make the difference. The job will be completed much faster.

It can determine whether a demolition job is carried out quickly and efficiently, without the need to force or pry with the tool.

The Unique DemaPower Cylinder Technology by DEMAREC

A proven innovation from DEMAREC since 2004 for the PremiumLine products.

In 2004, DEMAREC introduced the first generation of DemaPower cylinders to the market. Thanks to their immense power and extremely fast cycle times, this cylinder technology has remained a benchmark to this day. It was developed by Ruud de Gier, one of the cofounders of DEMAREC. This cylinder technology is still used in the Multi-Quick Processors, static pulverizers, the Dedicated Demolition Line tand rail cutters.

In 2017, the second generation of DemaPower cylinders, called DemaPower 2.0, was introduced. These cylinders feature eyelets on both the rod side and the cylinder base, enabling them to be integrated into the DCC 2-cylinder concrete shears and DXS mobile scrap shears. Thanks to this special cylinder technology, the DCC and DXS cylinders offer unparalleled high performance.

The key difference between DemaPower cylinders and conventional cylinders with a standard speed valve is that the cycle times of DemaPower cylinders are significantly faster, as the cylinder not only extends quickly (jaw closing) but also retracts quickly (jaw opening).

In practice, this results in a tremendous increase in productivity, as the productivity gain when opening the jaw is always 100%.

In comparison with cylinders that use boosters, the major advantage of the DemaPower cylinder is that it is always under pressure, while a booster cylinder must first build pressure, which takes time.

DemaPower Cylinders:

20 to 25% more power! (due to 20 to 25% more surface area)

Four pressure chambers instead of two, like conventional cylinders

Extremely fast cycle times thanks to a double-acting speed valve

The demolition and C&D waste recycling sectors in Australia and New Zealand are gaining momentum as governments, contractors and technology providers seek to balance booming infrastructure demand with pressing environmental goals.

In Australia, for example, the Dept. of Climate Change, Energy, the Environment and Water found that the construction industry generated around 29 million tons of waste in the most recent reporting year — accounting for roughly 39% of all waste nationwide.

Meanwhile, New Zealand generates an estimated 7 million tonnes of C&D waste annually, with around 40% of landfill inputs linked to construction and demolition, according to government and industry estimates.

James Murphy, Head of Sales - Asia Pacific at CDE, says that while both countries have aggressive targets, much more can be done with soils — the single largest contributor to construction waste. “If there’s an area that really needs development, it’s material standards. Not just locally, but globally, there’s a strong push towards performance-based material standards rather than the traditional, highly localised specifications.”

He adds that in practice, this can be a barrier. “For example, high-quality recycled soils and aggregates meet or exceed engineering performance benchmarks.

"Where performance-based standards have been applied, those same materials have been successfully used in major road and civil projects, proving the quality is there.

“Moving in this direction would unlock far greater use of recycled materials across Australia and help the sector scale much faster.”

Of course, the sector’s growth is closely tied to infrastructure pipelines. In Australia, road, transport and utilities projects remain one of the largest pipelines for recyclers.

A significant boost to companies come in the form of 998 road projects scheduled nationally by 2031, which, according to the Government, will require around 200 million tonnes of conventional materials, of which more than 95% come from just five sources: aggregates, asphalt, rock/bluestone, sand and cement.

However, its estimates suggest that 27% of these could be substituted with recycled alternatives — equivalent to more than 50 million tonnes of materials.

From soil recovery to smart demolition, new technologies are helping the sector in Australasia balance growth with sustainability, while project pipelines underpin confidence.

Breaking

New Zealand’s outlook is similarly positive. While short-term construction growth has softened, cost pressures are easing and medium- to long-term investment in transport and water projects remains strong.

Council-led urban regeneration in Auckland is also boosting both the volume and quality of recoverable materials.

SUSTAINABLE GOALS AND INVESTMENT CLIMATE

That circular goal is tied to a larger sustainability demand within the region, with companies being tasked with lowering greenhouse gas emissions which the Government says should “be

considered at all stages of the infrastructure lifecycle.”

With that, Murphy describes demand for low-carbon solutions as “immense”. He says: “In Australia alone the economic value of the construction materials sector is estimated north of $60 billion.

“Demand for low embodied carbon solutions is expected to rise significantly, recent reports estimate it could result in a billion dollar low carbon solutions market in the coming years.”

He adds that with the building and construction sector accounting for around 40% of global emissions, the opportunity to integrate recycled aggregates and soils into major works is significant.

“Ultimately, CDE believes that attitude and legislation must catch up with current technology and innovation to adopt an

ground?

application-based approach and enable the re-use of recycled materials to achieve the desired effect on the sustainability of natural resources.

“We’re seeing more mandatory reporting requirements and a stronger push from stakeholders to demonstrate environmental impact.

“Material efficiency, water use and emission data all influence procurement decisions.

"There is a raft of government policy, landfill levies, and procurement frameworks that reward low-carbon or recycled content.”

Meanwhile, Australia’s landfill levies and recycled-content procurement incentives are already creating an enabling framework, though inconsistent planning and permitting between states remain barriers.

In New Zealand, landfill levies and the government’s Waste Strategy are pushing the market in the same direction, although data gaps continue to limit fully targeted policymaking.

New Zealand also has a long way to go with land fill levies in order create a fund to incentivize investment in new technologies which will truly drive landfill diversion.

Interest rate reductions across both countries have improved financing conditions.

In August, the Reserve Bank of Australia cut the cash rate to 3.6%, while in New Zealand, borrowing costs are expected to stabilise in the 3–4% range in the next year.

Murphy says this could revive previously delayed projects and stimulate recycling demand: “We continue to watch the market closely, interest rates are forecast to hold steady in the 3–4% range over the next year, easing borrowing costs for businesses.

"This stability could revive previously delayed projects and enhance affordability across construction segments.”

Victoria outlines AU$55 billion of infrastructure investment

In March this year, the state of Victoria unveiled its draft 30-year infrastructure strategy which includes recommended investments of AU$55 billion that is says could provide AU$155 billion worth of benefits over the next decade if actioned.

Infrastructure Victoria named 50 priorities for the state across housing, energy, transport, health, social infrastructure and the environment as part of its draft 30-year infrastructure strategy. The strategy outlines 43 draft recommendations.

“Investing in new infrastructure is one way of building a more productive economy, and more will be needed as Victoria grows,” said Infrastructure Victoria Chief Executive, Jonathan Spear.

“But there is also lots the government can do to make better use of what it already has. The government can prioritise getting better use from its existing assets, improve how it maintains infrastructure so it performs better and lasts longer, and publish long term plans so that other governments, industry and not-for-profit providers can make better informed choices on where and when to invest."

The strategy highlighted how digital technologies can also produce big savings.

PROJECTS BRING CONFIDENCE

Perhaps underpinning project confidence, Liberty Industrial recently completed the demolition of cyclone-damaged infrastructure at Milner Bay Wharf in Australia’s Northern Territory.

The project scope included removal of structurally compromised sections to allow reconstruction works to proceed.

Remotely operated vehicles (ROVs) and daily 3D sonar imaging were deployed to assess submerged structures and guide dismantling in poor underwater visibility. In total, six tonnes of asbestos-containing material were safely removed and disposed of.

Project Manager Mathew Clenton, said: “Our ability to mobilise immediately and apply engineered solutions in such a remote and challenging environment ensured the safe removal of damaged infrastructure, and enabled our client to proceed with reconstruction works without delay.”

Meanwhile,

PROJECT Reinbrucke Demolition

CLIENT Hochtief Infrastruktur GmbH

The Rheinbrücke Neuenkamp had exceeded its technical lifespan. Tens of thousands of repairs were needed to keep it safe and operational.

To handle increasing traffic, a new bridge was built. In March 2024, the dismantling of the original bridge began— a project led by Hochtief and DDM. The demolition was carried out in reverse order of construction, requiring precise planning and accuracy.

One of the biggest challenges was developing a working method that met

DESPE

COUNTRY Italy

PROJECT Ex Centro Direzionale Alitalia

CLIENT Freccia Alata

In a changing urban context, the regeneration of the neighbourhood was being hindered by a large, abandoned building complex. Due to its location between inhabited buildings and busy streets, its demolition required an extremely careful approach to ensure safety, quietness and an absence of vibrations.

The objective was to work unobtrusively, respecting time, people and the environment. Every step was precisely planned, beginning with a detailed Operational Safety Plan.

The area was protected by barriers and electronic controls, and a real-time environmental monitoring system ensured compliance with regulatory limits. JUMBO, Europe’s largest excavator and a converted CAT 6015, was the star of the operation.

strict safety and environmental protection requirements. The safety of river traffic had to be continuously ensured.

No materials were allowed to fall into the water, and no work could be performed from the river itself. These restrictions demanded an innovative approach.

A critical element was removing the existing stay cables without the bridge collapsing under its own weight. To achieve this, DDM installed a 25 ton pylon cap at 50 m height to redirect the forces from temporary support cables and strand jacks.

The new bridge remained operational and river traffic uninterrupted. Despite challenges, the project was completed on schedule within 20 months. ■

Weighing 351 tons and equipped with an 8.1 m³ bucket, it could dig to a depth of 7.9 m and deliver 556 kW of power. This allowed the use of heavy equipment while maintaining a safe distance.

Its structure is made of low-strength carbon steels to detect abnormal deformations. Supported by other large excavators, the team worked to hit deadlines and keep dialogue with the community. ■

MAX WILD

COUNTRY Germany

PROJECT Construction of crossover

A3/A67 Mönchhof-Dreieck

CLIENT Die Autobahn GmbH des Bundes Bridge demolition during traffic was the challenge for Max Wild during the demolition work of the connecting ramp above the highways A3 and A67.

To ensure this process was carried out efficiently and safely while the highways were in use, the bridge superstructure had to be lifted 5.20 m first, and then a 130-m-long and 1,200 ton heavy supporting structure was inserted. Max Wild dismantled the existing bridge, without traffic interruption. 6,000 tons of concrete was demolished and fully recycled. Prior to the demolition, a supporting framework was inserted.

The supporting framework provided protection for the highways below during the demolition works. For the supporting framework to be inserted, the 104-m-long and approximately 3,200 ton heavy bridge superstructure was lifted 5.20 m.

Max Wild ‘stacked’ the bridge superstructure upwards using (20) hydraulic jacks. The jacking operation was controlled with a synchronized lifting system developed by Max Wild specifically for this project.

Max Wild was responsible for the complete services including project management, design, and the execution of all deconstruction works, and has completed the project ahead of schedule. ■

COUNTRY Australia

PROJECT Chifley South Tower Demolition

CLIENT Built Pty Ltd

The Chifley South Tower project showcased collaboration amid complexity. Mann carried out the demolition of the South Tower whilst the adjacent 43-storey Chifley North Tower remained fully operational, despite thousands of services running through the demolition zone.

The project required extensive unity, with Mann leading the development of a staged program, facilitating daily interface meetings and workshops to ensure every move was aligned with all involved.

A major challenge was the hand stripout of 18,000 m² of office fit out due to limited service disconnections. This enabled service trades to follow behind, identifying, isolating, and rerouting live systems without disrupting North Tower operations.

An evolving scope on the retention system became a collaborative highlight. Initially a temporary measure, it served as the client’s permanent retention solution. ■

HAYWOOD CRUSHING DEMOLITION

COUNTRY Wales

PROJECT Brackla1 Car Park, Bridgend

CLIENT Bridgend County Borough Council

Appointed by Bridgend County Borough Council, Haywood was tasked with the deconstruction of a deteriorated five-storey concrete structure, constructed using the rarely seen lift slab method, an inherently unstable and interconnected system.

Surrounded by two major supermarkets and a live railway line just 2 m away, the project demanded intricate planning and coordination. Haywood’s engineering-led approach incorporated over 400 steel props and column bracing to ensure structural stability throughout the process.

Drawing lessons from past structural failures, the company collaborated closely with structural engineers, Network Rail, and local stakeholders to devise and approve a demolition methodology that prioritised safety, continuity, and precision.

Despite the complexity and high-risk environment, the company delivered the project on time and within budget.

The site was operated under a bespoke safety regime, which included real-time air quality monitoring, dust and noise control, and night works to protect live infrastructure. The result: zero incidents, uninterrupted rail operations, and full client satisfaction. ■

For this abatement and full demolition project, Trifecta first had to understand how it was built in order to deconstruct it safely. The team identified structural connection points between large concrete blocks and prepared them for removal by grinding and burning through embedded reinforcements. A 550 ton crane was then used to lift the tower sections down for processing and recycling.

A Volvo 380 excavator was then used to complete the remaining demolition. Trifecta delivered the project on schedule, with no safety incidents, and with a 65% recycling and salvage rate. to-workp ■

PROJECT Cottam Power Station Chimney

CLIENT EDF Energy

The 200 m chimney at EDF’s decommissioned Cottam Power Station in Nottinghamshire was brought down with unprecedented precision using a pioneering explosive method.

Situated among live infrastructure, including a gas main, absorbers, and electricity substation, and in close proximity to residential properties, the complex operation required a meticulous level of control.

Rather than toppling the chimney in traditional fashion, the team employed a “telescoping” collapse technique, causing the structure to implode vertically.

The result: vibrations reduced by 75%, debris confined to a 35m radius, and zero damage to surrounding assets. A Comparative Risk Assessment found this method safer than alternative approaches, including piecemeal demolition, by option of extended high-risk work at height. ■

PROJECT Tropicana Las Vegas

Hotel - Paradise Tower and Club Tower

CLIENT GGG Demolition

CDI performed the design and implosion of the two 23 storey Tropicana Hotel and Casino towers using over 1,421 lbs of dynamite.

Vibration monitoring was conducted at numerous locations. Peak particle velocity and air overpressure readings were a fraction of limits allowed by local, State and federal regulations. CDI iaised with various local departments, including Clark County Police and Fire & Public Works Departments.

It also met with adjacent property owners of casinos, hotels and condominiums on how to mitigate the impact of the implosion and street closures on their property.

From the structural complexity of the two towers, to the coordination and timing required for the pyrotechnic show thereafter, this was one of the most complex projects CDI has ever undertaken.

COUNTRY England

PROJECT Sizewell A - Turbine Blocks

CLIENT Erith Group

The decommissioning of the Sizewell “A” nuclear power station involved demolishing the redundant turbine hall and removing its reinforced concrete turbine bases.

The blocks, measuring 92 m by 19.8 m by 10.4 m, needed to be removed to clear the land and advance decommissioning. Due to the proximity of the operational Sizewell “B” (SZW B( reactor, the project had to comply with strict nuclear regulations and minimise disruption.

To accelerate the process, PDC implemented a preweakening technique using controlled explosives, reducing the mechanical demolition timeframe from six to two months and limiting noise, vibration, and disturbance to workers and the community.

The method used the most significant single deployment of electronic detonators and NG cartridge explosives on an operational UK-licensed nuclear site. The work adhered to strict standards, ensuring that risks were minimised as far as reasonably practicable.

Collaboration ensured safe and efficient execution. The project enabled the processing of 4,980 tons of concrete, a 4-month program reduction and a carbon savings of 78.4 tons. ■

PROJECT Demobilization of the Centralized Workshop

CLIENT EAC - Electricity Authority of Cyprus

This project involved the demolition of six 30 MW oil-fired steam units and auxiliary equipment in the EAC power plant.

The work took place over a large and complex area, including asbestos abatement, closure of turbine cooling ducts and covering of contaminated areas.

Asbestos removal was one of the first activities, carried out in parallel with the demolition of external structures.

After the certified clean-up of certain areas, the main demolitions began: first the administration building, then the ducts, the boilers and the boiler itself.

This allowed excavators access to the turbine hall. A major challenge was the closure of the channels below sea level, which required solutions to manage the tidal water and analysis to identify the connections between the channels.

Once turbine demolition was completed, the controlled demolition of six 40-m-high metal chimneys proceeded, monitoring vibrations to protect nearby turbogas plants.

Finally, four 17,000-litre tanks were demolished with a special shear designed by Despe. All activities were completed without incident, meeting safety and environmental standards.

PROJECT Dismantling and associated works at Motor Oil Hellas Corinth Refineries

The decommissioning and dismantling project of the U-1100 unit at the Motor Oil Hellas refinery in Corinth was a highly technically complex operation, carried out in an active and highly constrained operational environment.

The objective: to remove obsolete and damaged structures, ensuring the integrity of adjacent facilities and the absolute safety of personnel.

The intervention area included pipe-racks, process columns, air coolers compromised by fire and metal structures, with operations at height and in an ATEX environment.

The team, consisting of 20-25 specialised Despe operators, working in continuous shifts, under constant coordination with MOH technicians.

The critical issues addressed by Despe included the presence of active lines, risk of product residues, structural instability and environmental constraints.

Each phase was preceded by targeted training, operational simulations and daily briefings. Advanced technologies such as the Fly Demolition System and hydrocutting robots allowed remote operation, reducing risks.

Demolition took place in a selective and controlled manner, with progressive removal from top to bottom. The project ended without incident, with the complete separation of the U-1100 unit, the recovery of the required components and the absence of environmental impacts.

An operation that has combined innovation, rigour and safety, becoming a reference model for refinery decommissioning. ■

Project Phase 1 A DecommissioningFacilities Dispositioning

This project involved the partial demolition of a turkey processing facility, carried out as part of its industrial conversion into a chicken processing plant.

The primary objective was to free up space for expansion, allowing a significant increase in production capacity—without compromising operational safety at any stage.

The demolition scope included the removal of 4,800 m² of non-friable asbestos roofing, dismantling of insulated partitions, 38-meter-span steel trusses (11 m high), metal ducting frameworks, and reinforced concrete structures.

These tasks were performed adjacent to active food production zones and live ammonia (NH₃) pipelines, making safety the project’s top priority.

A comprehensive safety strategy was implemented, including real-time remote video monitoring of demolition zones, ammonia gas detection systems on all machinery, and strict access control protocols.

Workers received specialized training in ammonia hazard management, respirator use, and emergency response procedures.

Daily safety briefings and coordination meetings with the client ensured full alignment and rapid response to any emerging risks.

The demolition was executed in three phases, with staged handovers to the new construction team. Zero health or safety incidents were recorded during the entire project— despite the high-risk environment.

All waste was managed responsibly: over 1.2 million kg of ferrous scrap were recycled through AZA, and mixed debris was processed at Revaloriza using advanced sorting systems. ■

SUMMIT 2O25 DEMOLITION

CONFERENCE - AWARDS - NETWORKING

The 17th year of the premier international event honouring excellence and innovation in the demolition & recycling industry.

Managing complex environmental liabilities has never been more challenging. Legacy contaminants such as PFAS, hydrocarbons, and heavy metals are increasingly shaping the way industries approach demolition, remediation, and recycling.

For companies tasked with cleaning up industrial sites or repurposing brownfields, the challenge is as much strategic as it is technical: how to comply with regulations, mitigate corporate risk, and deliver sustainable outcomes for communities and ecosystems.

For Truong Mai, Global Service Lead for multinational consulting firm ERM that specialises in sustainability, the importance of a proactive and holistic approach is essential. “PFAS has become much more prominent over the past decade,” he says.

“While we treat it like any other contaminant, there’s a newness factor that involves more exploration and litigation.

“We also consider it through a corporate risk lens: supporting a PFAS manufacturer is very different from working with a company that uses PFAS in consumer products.”

Mai says that the most effective strategies start with clarity.

“Helping clients define how they want to approach potential exposures and how that fits

Remediation reimagined

Legacy contaminants are forcing companies to rethink how they manage environmental liabilities.

with their business plan is critical. That clarity at the start dictates the tactics that follow.”

Equally important is proactivity.

Companies that address issues early tend to see far more positive outcomes than those that wait until they are compelled to act.

Digital tools have become increasingly central to this approach. Large remediation projects generate vast volumes of structured and unstructured — analytical, geochemical, physical, etc, and managing it efficiently can mean the difference between delays and smooth project execution.

SINGLE APPROACH

Mai explains: “It’s critical, and it’s a journey rather than a destination. We generate huge volumes of structured and unstructured data and have spent years automating data management processes, improving data quality and security, and reducing manual work.

“A single data management approach and platform now ensures consistency, efficiency and cyber security for our 1,400 consultants.  Clients expect the same quality whether they are in Asia, Latin America, North America, or Europe."

AI is also playing a role, acting as a knowledge-sharing “answer machine” that helps consultants access collective expertise across the network. Looking ahead, automation of

recurring processes promises further gains for both clients and service providers.

SOIL ASSESSMENT

While AI and data platforms optimize decision-making, hardware innovation is also transforming remediation.

French start-up Iridesense, in collaboration with Bouygues subsidiary Colas Environnement, is developing a multispectral LiDAR device capable of detecting hydrocarbon traces in soil from distances of up to 100 m.

The device uses laser scanning and AI to generate 3D maps that highlight contaminated areas in real time.

Traditional soil assessment relies on physical sampling and laboratory analysis, a process that can disrupt project timelines.

Iridesense’s technology promises immediate on-site results, reducing delays and costs while improving accuracy.

Pilot tests have demonstrated that it can detect contamination levels above 500 mg/kg of dry mass, and the device operates under any weather or lighting conditions.

Compact and portable, it can be deployed quickly on site, providing high-resolution maps accurate to 10 sqcm.

“Although still in the evaluation phase, we see potential in this technology to enhance the efficiancy and sustainability of our soil remediation projects,” says Arnault Perrault of Colas Environnement.

Iridesense co-founder Nadine Buard adds: “We are working to refine the

Cleaner recycling

BT-Systems GmbH, has developed Redwave XRF, which combines X-ray fluorescence with spectral analysis to distinguish individual aluminium alloys even in soiled or mixed streams.

The company says this boosts material purity, reduces contamination, and increases market value — particularly for automotive and construction.

By ensuring hazardous fractions, including PFAS-containing materials, are identified and managed, Redwave adds that it is helping the recycling chain contribute to the circular economy while supporting sustainability goals.

multispectral LiDAR to better meet industry needs and advance the rehabilitation of contaminated sites.”

SUSTAINABILITY AT THE CORE

Meanwhile, sustainability is no longer an add-on; it drives decisions from the earliest stages of remediation, and Mai notes that the selection of the remedy itself has the greatest impact. “The chosen remedy has the greatest impact on sustainability. For example, is it better to dig and landfill material, or can risks be managed through in-situ or naturebased remedies that add value to ecosystems and communities?

“Stakeholders are becoming more receptive to these alternatives where they are effective and economically viable.”

Beyond the technical choice of a remedy, other factors shape sustainable outcomes such as supply chain management, local sourcing, renewable energy, climate resilience, and community engagement.

Reuse strategies are evolving too. Clients are considering options such as adding green space, supporting biodiversity, or developing land for renewable energy, rather than simply building the next high-rise.

“It’s less about the shiny new development and more about the most

valuable reuse for the community and environment,” Mai adds.

GLOBAL EXPERTISE

Operating across multiple geographies also adds another layer of complexity for companies. “Global themes exist, but local nuance is crucial,” Mai explains. “What’s possible in the US or UK may not be in Chile. What matters to First Nations in Canada may differ from indigenous populations in Brazil. Our experience across regions helps us tailor solutions to each location, industry, and client. An oil refinery has common technical challenges worldwide, but how it operates within its local community can vary dramatically.”

This tailored approach is increasingly vital as industries face cost pressures.

By combining global advisory insight with solutions ranging from AI-driven data platforms to multispectral sensors, companies can tackle complex liabilities efficiently while supporting sustainable outcomes for communities and ecosystems.

Mai observes: “The integration of advisory insight with digital and sensor technologies is creating a new paradigm in remediation — one that’s smarter, greener, and more accountable.” ■

Raising standards

While the high-reach excavator may stand as a sign of demolition force on urban skylines, the capabilities of these machines can, and do, stretch far beyond the standard use cases.

No longer are they confined to bring buildings down, but also to carry out works after the fact, in particular with material recovery.

Jan Breburda, Special Applications Product Manager, Develon, tells D&RI: “At Develon, we see high-reach machines not just as tools for taking buildings down, but as critical enablers of the circular economy in construction. The role of high reach excavators is evolving from brute-force demolition toward selective deconstruction, where precision is critical for separating materials cleanly.

“This approach supports the recovery and reuse of high-value building materials. By enabling more precise dismantling, our machines help contractors maximize what can be recycled, reused or resold — turning demolition into the first step of material lifecycle optimization.

“Ultimately, we see high reach excavators playing a more strategic role in urban regeneration — where the teardown of old buildings is seamlessly connected to the materials feeding new construction.”

SPECIAL APPLICATIONS

Meanwhile, OEMs are continuing to expand specialist ranges designed for high-reach demolition and heavy tool applications.

Precision,

sustainability and adaptability are

reshaping how contractors view the use of high-reach excavators.

In its high reach configuration

In that respect, Develon now offers a line-up of four dedicated demolition excavators: the DX140RDM-7, DX245DM-7, DX380DM-7 and the flagship DX530DM-7. Covering operating weights from 22.5 to 71

Hercal adds 200 ton Liebherr demolition machine to fleet

Spain-based demolition and earthmoving contractor Hercal has added a Liebherr R 980 Demolition to its fleet.

The machine, which has a reach of over 60 m and an operating weight of 200 ton, is the first of its kind to be delivered to the Iberian Peninsula.

Hercal said the acquisition of the excavator aligns with the company’s wider growth strategy. The new machine joins an existing fleet of Liebherr equipment that includes an R 938 crawler excavator, LH 40 material handler, L 580 XPower and L 566 XPower wheel loaders, and an LR 636 crawler loader.

Develon now offers a total of four specialised demolition machines.

tonnes, the range provides maximum pin heights of 16 to 31 m and tool capacities up to 3 ton.

All four models are powered by Stage V engines, delivering outputs of up to 294 kW (394 hp). Each unit features a modular boom design with a hydraulic locking mechanism for fast configuration changes, plus a tiltable cab of up to 30° to improve visibility in highreach applications. Transport is facilitated by hydraulically extendable undercarriages, reducing width to just 2.5 m.

The new DX140RDM-7 introduces further options, including a unique ‘Monolithic’ variant with a dedicated demolition arm and no interchangeability. Alternatively, a dual-purpose version allows operators to switch between demolition and digging arms, with a total of three possible configurations. A dedicated stand and quick-change hydraulic couplers simplify the boom changeover process.

Italian manufacturer Laurini Officine Meccaniche has also extended its offering in the segment with the Settanta, a 33 ton unit launched to mark the company’s 70th anniversary. The machine offers four interchangeable boom options: a 24.5 m high-reach demolition boom (3,000 kg tool capacity), a triple boom (14 m, 6,000 kg tool capacity), a telescopic boom adjustable from 25 to 30 m (2,000 kg tool capacity), and a lattice lifting boom with hydraulic winch.

The Settanta is designed to match the performance of a converted 45 ton excavator, but incorporates compact transport dimensions (2.5 m width), a hydraulically adjustable undercarriage (2.5–3.7 m), and a reinforced slewing ring for heavy loads. Powered by a 257 kW Scania DC09 engine, the machine features a Danfoss loadsensing hydraulic circuit with a 380 bar booster, an automatic greasing system, and Laurini’s Hydraulic Hoses and Wiring Quick Coupling System for automatic connections.

structures that carry the city’s “L” train.

With the project located in a dense urban setting, space constraints and community impact are critical factors.

BOOTS ON THE GROUND

While OEMs push boundaries in design and flexibility, contractors are proving the value of specialist equipment in the field.

In the US, Walsh Group is relying on a fleet of Volvo excavators and wheel loaders for the $2.1 billion Red and Purple Modernization project in Chicago.

The ongoing works include demolishing and rebuilding century-old elevated

Rick Anderson, General Superintendent for Walsh, explains: “There’s a lot going on and everything’s tight. For this demolition job, we’ve got sheet removal. We’re breaking up concrete. Haul trucks are moving material in and out, plus there’s general cleanup. To navigate these challenges, Walsh is operating 13 Volvo ECR235 excavators, two ECR355 excavators, and four wheel loaders (L90–L120).

The short tail swing excavators, paired with tiltrotators, provide the reach and versatility needed to complete demolition and handling tasks within the confined site.

SMARTER, SAFER, CLEANER

Urban demolition is increasingly about compliance, sustainability and safety. For that reason, Breburda believes the pressure on OEMs goes beyond engineering machines for higher reach.

“Cities are setting stricter regulations, and contractors are actively looking for solutions that help them meet environmental and noise requirements on site," he says.

“At Develon, we recognize this shift as part of the industry’s move toward more sustainable solutions. While we don’t currently offer an electric high reach excavator, it must be said modern Stage V diesel engines have already brought a significant reduction in harmful emissions like NOx and particulate matter.

He also points to the increasing role of digitalisation in supporting both productivity and safety.

“Technology plays a pivotal role in making high-reach demolition not only safer but also more productive and measurable. Our latest high reach machines are equipped with the MyDevelon Telematics and Fleet Management system."

That integration of telematics, assist features and smarter design is, he argues, central to the future of high-reach work. ■

Bringing down one cooling tower is complex, but bringing down 10 requires stringent planning.

In what is a world record for the most cooling towers demolished by explosives in a single event, Brown & Mason orchestrated a planned blowdown that saw the massive concrete structures fall exactly as designed.

In this exclusive Q&A, Explosive Demolition Manager Rikki Isgar explains the year-long preparation process, the technical adjustments required for reinforced structures, the logistics of using nearly half a tonne of explosives, and the safety considerations of the project.

What makes this a record-breaking project?

The record was the most cooling towers in a single event demolished by explosive means. This had to be completed within 40 seconds and we achieved it within 10.

Regarding the planning method, how did you go about it?

There has been a lot of design work and enabling. They’ve been working on the towers for approximately a year now from desilting and segregation of all recyclable materials that were internal.

In the last six months we’ve been drilling leading up to the last month of charging and culminating in today’s event.

How did you decide on the approach?

Through many years of performing events

Inside a record-breaking blowdown

such as this, we’ve repeatedly collapsed cooling towers in this manner.

There were significant differences with a few of these towers due to their reinforcement. They had additional columns added to them at a later phase. There was steel, which led our design in a slightly different manner, but as you can see, they reacted in the same way as all of the others.

How many charges did you use?

We used 16,700 over all of the towers. It’s approximately 2,000 per tower. We were just shy of half a tonne of explosive across the entire event.

We initiated the event in approximately 330 milliseconds. That allowed for keeping air over pressure and ground vibration to a minimum, but also ensuring that there was no interference between each tower to the opposing towers.

How close was it to your models?

All of the towers reacted exactly as we designed them to, and we’re really happy with the results.

What’s the next stage for the project?

The next part of the project will be the crushing and processing of all the aggregate materials on site.

We’ve already had five blowdowns prior to this that have involved steel structures which have gone to recycling and now and earlier this year we had the chimney and this is the last phase of the explosive demolitions on this site.

What percentage of the materials will be recycled?

I think at the moment we’re assuming about 98%. So, we’re well up there with recyclables.

What were the biggest challenges?

Obviously, the proximity to the National Grid infrastructure. We are slightly further away, but we’ve got the live power station on this site along with high pressure gas main. There’s also the overhead infrastructure for National Grid.

We had some properties that needed to be evacuated because they fell within the exclusion zone. So, there was multiple challenges with dealing with the event in that aspect, ensuring that everyone was kept safe and all environmental and safety precautions were complied with. ■
