Bringing teams together The success of your project relies on effective coordination and communication. That’s where we come in. Our Design Management team, comprised of highly experienced designers, has a proven track record of successfully delivering projects across various sectors.

We identify design issues, scope gaps, nonconformances, and by engaging the supply chain at an early stage we can facilitate commercial opportunities. Design assurance protects your margin and enables scope certainty. We establish defined hold points with QA processes and gateway sign off for the design to save money, improve quality and reduce risk in the construction phase of projects.

To fulfil these responsibilities, our design managers possess a diverse skill set and expertise.

This includes a comprehensive understanding of the construction and property industry, proficiency in technical aspects of design and construction,

knowledge of regulatory requirements, planning and programming skills, contract and commercial acumen, negotiation prowess, and effective presentation abilities. By leveraging these capabilities, the design manager can effectively lead design projects, drive collaboration, and deliver high-quality outcomes that meet client expectations and industry standards.

The key to success is the appointment of suitably qualified and experienced personnel, carrying appropriate levels of professional indemnity insurance in the delivery of design and engineering activities, products and services. For this reason, our involvement is most effective when we are appointed at the tendering stage, allowing us to support your tender or bidding process.

Design Management Offer Our Design Management service offers a comprehensive platform designed to complement, not replace, your existing processes and procedures. It aims to enhance consistency in project controls throughout the project lifecycle. We recognise that many of our clients have processes in place which we will need to adhere to. Where this is the case we request clear onboarding, whereby the client’s design management plan and work instructions are made clear.

Our service focuses on three key pillars: Coordination: We provide guidance to ensure high-quality design solutions that align with your needs and project requirements.

Communication & Collaboration: We create effective channels among all parties to ensure a smooth flow of design and production information. By fostering strong relationships and promoting information sharing, we enhance coordination and streamline decision-making.

Risk Mitigation: We play a crucial role in risk mitigation and proactive problem-solving. By identifying and addressing potential design issues before they escalate, we help de-risk the project and maintain progress towards successful outcomes.

GREATER LONDON AUTHORITY

New City Hall Location: London Expertise Area: Design Management The Greater London Authority, the London Assembly, and the Mayor of London embarked on a significant refurbishment project for their new headquarters at the former Crystal building near Royal Victoria Dock. Originally an exhibition centre for sustainable architecture, the building was renamed “City Hall” in December 2021.

DB3 was engaged by the contractor, ISG, to oversee the design management role, playing a pivotal part throughout the project’s lifecycle. As part of our responsibilities, we facilitated communication and collaboration among all designers to ensure a smooth flow of design and production information aligned with the construction schedule. Our team actively managed design risks, contributing to planning and coordination efforts that added substantial value.

Throughout the project, we conducted workshops, identified requirements for mock-ups, benchmarks, and samples to guarantee successful delivery, and coordinated and tracked requests for information from designers to the client.

Our scope also encompassed collaboration with architects and specialist fabricators to complete bespoke public spaces such as the London Living Room, Committee Rooms, and the Chamber. A noteworthy contribution was a large backlit Corian screen facing the committee rooms, featuring microperforate acoustic veneered timber, oak slat panels backed with green acoustic felt, and a backlit stretch acoustic ceiling with pendant lighting within a felt soffit. In the Chamber, we ensured the materiality echoed this aesthetic with timber privacy fins and a halo of pendants above the triple-height space, complemented by a public viewing gallery.

STRUCTURE TONE

Devonshire House Location: London Expertise Area: Design Management DB3 were appointed as Design Managers on TA Associates’s new London headquarters at Devonshire House, a Grade II listed landmark overlooking Green Park. The project demanded a careful balance between heritage sensitivity and the delivery of a modern, high-performing workplace.

Our role centred on coordinating design packages, managing approvals, and overseeing samples and mock-ups to keep decisions moving.

DB3 worked with lead architect Hassell Studio as and main contractor Structure Tone. Throughout the project, DB3 acted as the link between

architect, contractor, and client, making sure Hassell’s design intent was preserved while addressing the practical demands of construction.

Heritage restrictions limited what could be changed and required careful, precise detailing.

Bespoke features, including the central stair and custom joinery, needed close coordination, while tight procurement timelines meant decisions had to be made quickly and approvals kept moving to keep the project on track.

DAVID LLOYD

Park Club Leisure Centre Location: London Expertise Area: Architecture, Design Management The design management scope for the extension to the Park Club Leisure Centre involved a comprehensive approach to addressing various aspects of the site, integrating with the existing building layout, and fulfilling the client’s design brief requirements, which included implementing a new internal design guide. One of the main focuses was to reconfigure the internal spaces of the leisure club and increase the overall floor area to align with current market expectations and cater to the needs of the patrons. This involved strategically balancing the maintenance of core elements of the existing structure with the incorporation of new features and facilities to enhance the overall experience.

Key elements of the design brief included the improvement and expansion of changing facilities, the addition of a new wet spa, the retention and refurbishment of the pool hall, the reconfiguration of the reception and club lounge areas, the provision of a new family lounge and children’s activity rooms, the extension of gym facilities, and the incorporation of new studios. The outdoor

facilities aspect of the brief further added complexity to the project, with requirements for a spa garden featuring an outdoor spa pool, landscaped seating areas, and a fenced enclosure.

As the design management lead for the principal contractor on this complex refurbishment and extension project, DB3 was committed to ensuring the seamless integration of design elements, construction processes, and project requirements. Our role involved coordinating with the architect, engineers, and subcontractors to maintain design intent while meeting budget and schedule constraints. By facilitating regular design coordination meetings, conducting value engineering exercises, and resolving design conflicts in a timely manner, we aimed to enhance collaboration and minimise project risks.

Leveraging our expertise in design, we strived to deliver a high-quality leisure centre that met the expectations of both the client and the market.

BELL BUILDING PROJECTS

Multiple Schemes Location: UK-Wide Expertise Area: Design Manager DB3 are working in collaboration with Bell Building Projects in the delivery of complex recladding and fire remediation schemes across the UK. Acting as Design Manager, we provide specialist expertise in coordinating the design process, ensuring compliance with evolving fire safety regulations, and supporting the delivery of safe, fully compliant residential buildings.

Cavalier House, Ealing DB3 is providing Design Management services to Bell Building Projects on behalf of Ridgeland Properties Ltd for the recladding of Cavalier House, a High-Risk Building (HRB). Following an external wall appraisal, combustible materials were identified, requiring replacement to meet fire safety standards. Products containing EPS, PUR, and PIR are being substituted with systems tested to BS 8414 or achieving a Euroclass rating of A2 or better.

The works include the installation of horizontal and vertical cavity barriers and closers, along with the replacement of:

Spandrel panels to the external window system across all floors

Spandrel and insulated cladding panels to penthouse apartments at roof level

Insulated cladding panels forming parapet walls and gable ends

Combustible timber decking to cantilevered balconies

The remediation programme will deliver compliant, non-combustible external wall systems in line with Building Regulations and British/ European Standards. Bell Building Projects hold full design responsibility, with the design phase scheduled at 25 weeks and the site programme at 50 weeks. The PCSA period is projected at 40 weeks, including a Gateway 2 review, with a full plans submission lodged with the Local Authority.

Lancefield Quay, Glasgow We are also completing the Design Manager role for the refurbishment of Lancefield Quay, a large residential development comprising a U-shaped

arrangement of apartment buildings, 6–14 storeys high, across 16 stair cores. Constructed in two phases between 2003 and 2006, the buildings are now subject to major remediation works following the discovery of combustible external wall materials.

The works involve the removal of aluminium composite material (ACM) cladding (the same type used on Grenfell Tower) together with the existing render. These will be replaced with noncombustible alternatives, ensuring the safety of residents and compliance with Building Regulations. In addition, further intrusive investigations are being carried out to assess areas that remain uninspected, providing detailed information to inform the design and specification of remedial works.

Investigations are focused on façade systems and interfaces, including cavity barriers, cladding types, and junction details. The works are expected to cost in the region of £14m.

Echo Building, Newcastle upon Tyne DB3 are supporting Bell Building Projects as Design Manager on the Echo Building, an 11-storey residential block housing 180 apartments, where essential fire remediation works are being delivered. The scope of works includes:

Removal of the existing perimeter fascia

Installation of additional steel supports and new fascia panels

Removal of combustible spandrel panels

Installation of cavity barriers at floor slab level

Installation of new non-combustible vertical spandrel panels

The project presents additional challenges with residents remaining in situ throughout the programme. DB3’s role is to ensure coordinated design development, sequencing, and compliance, supporting Bell Building Projects in delivering a safe, regulatory-compliant solution with minimal disruption to residents.
