Project Overview The British Museum is seeking to appoint a Principal Contractor for a programme of essential roof repair and replacement works to the Grade I listed Round Reading Room, located at the centre of the Museum. Building Context and Heritage Significance The Round Reading Room was designed by Sydney Smirke and completed in 1857. It is a structure of exceptional national heritage significance, combining iron primary construction with brick masonry, a copper-clad dome, and a fully glazed central lantern. The roofscape comprises three elements: a perimeter flat roof known as the Snow Gallery Roof; the copper dome in batten-roll standing seam; and a twenty-sided glazed lantern incorporating patent glazing, timber sidelights, and a decorative internal laylight. Scope of Works The works span four principal areas: • Snow Gallery Roof: Removal of an existing membrane and mineral wool flat roof build-up down to the concrete deck. Installation of a warm roof with cold-applied liquid waterproofing membrane, including upstands, penetrations, and new lightning protection. • Copper Dome Conservation and Repair: Close-quarters condition survey and conservation-led repair from temporary scaffold, including localised copper panel replacement, seam and flashing repairs, and full replacement of the lantern base apron. Works must be undertaken by heritage-accredited metal roofing specialists. • Lantern Glazing, Windows and Refurbishment: Full replacement of the existing patent-glazed lantern atop the dome with a bespoke tiered steel glazing bar system; repair and redecoration of external windows and internal sliding sashes; installation of BMS-linked actuators; and in-situ conservation of the historic internal laylight. • Maintenance Access and MEP: Upgrade of permanent access provisions including fall-arrest and restraint systems, internal walkway refurbishment, replacement heating, LED lighting, and BMS integration. The project includes a number of CDP items, including, but not limited to, scaffold and temporary works, tiered patent glazing, access systems and MEP systems. Key Project Constraints • Access and Logistics: The site is entirely enclosed within the Foster+Partners Great Court roof, with no direct external crane access, and the Round Reading Room is to remain open to staff and the public for the maximum time possible during the works. A Stage 4 design for a cable-restrained scaffold system and temporary roof has been developed by an access specialist and needs to be completed as a CDP item, alongside a full lifting, logistics and evacuation strategy. • Operational Environment: Although temporary periods of closure and exclusion will be possible in the Round Reading Room, the Museum will remain open without restriction throughout the construction period. Noise and vibration limits apply, and protection of the Reading Room interior and collections is mandatory throughout. • Hazardous Materials: Asbestos-Containing Materials and lead-based paints are confirmed present within the lantern and on historic ironwork. Safe methods of removal must be provided during the works. Procurement and Programme The project will be procured via a single-stage traditional tender under a JCT Standard Building Contract 2024 with Contractor's Design Portion. A contractor will be selected on capability, heritage experience, and commercial submission, with appointment aimed for November 2026, a start on site in January 2027 and Practical Completion targeted for Q1 2028. Contractors will be required to demonstrate CDP and construction experience across: conservation of Grade I or II* listed structures; heritage metal roofing; liquid-applied roofing; bespoke patent glazing fabrication; heritage window joinery and ironwork; works within live occupied public buildings; and complex temporary works in constrained environments. Due to the confidential/commercially sensitive nature of information that will be included in the associated tender documents we require that interested suppliers enter into a confidentiality agreement before they are given access to the tender pack. A copy of the confidentiality agreement is available by request via email to [email protected]. The terms of the confidentiality agreement are not subject to negotiation.
The British Museum brings together the history of humankind, all cultures of the world spanning millennia. It connects us to our past and to each other. It is a place where everyone is welcome, where many voices meet to understand, and to question what brings us together and what separates us. It is a place of exploration and a place of inspiration. The collection that the Museum holds in trust for the world is of unparalleled breadth, depth, beauty and significance. A truly global resource, free and available to everyone. The Museum's role is to enhance and make accessible the collection through research, through interpretation, through display, through lending, and to share what it learns, as well as the process of learning, with others. With this matchless position comes a responsibility to ensure that this work can continue, ensuring the collection is cared for and accessible for generations to come, and that the Museum remains a centre of excellence and is continually relevant into the 21st century. The physical manifestation of the British Museum in Bloomsbury is iconic. It comprises almost an entire city block in one of the most intricate and established parts of central London. It is a treasured national icon within a conservation area that is, in itself, emblematic of the Capital. The Museum has an internal floor area of over 100,000m2, within a footprint that is packed with a diversity of buildings; the estate is Grade I listed, with perimeter properties that are listed Grade II. Each part of the Museum contains, iconic, often sizeable and irreplaceable items from the collection, and each is visited by many thousands of people, every day. Space on the site is both limited and precious, especially in terms of gallery spaces. The original quadrangle was designed for 100,000 visitors per annum, a figure that was already far exceeded in the 1850s. As it stands, annual visitor numbers to the Museum now regularly exceed six million. Today, there are heightened security requirements and a fundamental need to ensure inclusivity and access, as well as enabling intuitive wayfinding, addressing dilapidations, and creating an environment where people can connect with the collection, and by doing so, with each other. The Western Range Programme focuses on a substantial part of the estate that is in urgent need of both repair and re-imagining. This offers the Museum an opportunity to make a statement of its future intent, through reimagined galleries, new state-of-the-art storage facilities and engaging contemporary architecture, in juxtaposition to the highly significant and already celebrated listed buildings on the site. A multi-disciplinary design team led by Lina Ghotmeh Architecture has been selected to deliver the Western Range programme which is currently at the end of RIBA Stage 2 in the design process. Despite appearing as a single entity, the Western Range comprises a miscellany of 10 separate buildings which have been added to Robert Smirke's original Grade I listed Museum; as a result, the exact extent of the red-line boundary and phasing for this project is dependent on a number of interlocking considerations. The proposed project outline can be seen in the attached documentation. In the region of 15,000m2, it accounts for almost 15% of the floor space within the Bloomsbury site, in a warren of inflexible and static rooms. Further, recent surveys indicate that the existing building fabric and infrastructure are in a state that is below modern expectations. It comprises around 7,500m2 of gallery space and currently houses the Ancient Egypt, Ancient Greece (including the Parthenon Sculptures), Rome, and Ancient Assyria and Middle East collections, along with 4,500m2 of back-of-house collection storage. The delivery of the Western Range redevelopment will take place within a complex and highly sensitive operational environment, requiring construction works to be carefully planned and coordinated alongside the ongoing activities of the British Museum. As a live cultural institution, the Museum must continue to provide safe and effective access for visitors and staff, while ensuring the protection, movement, and management of its collections throughout the construction period. The project presents a number of unique challenges, including working within a heritage setting, constrained site conditions, restricted access, neighbouring property interfaces, complex logistics requirements, and the need to coordinate multiple stakeholder requirements. A Security Consultant is therefore required to provide specialist, project-specific expertise to develop and deliver a coordinated Security Strategy that protects visitors, staff and collections, addresses the Museum's status as a Sensitive Project, and supports the successful delivery of the Western Range Programme. The Security Consultant will act as the lead security advisor to the Project, working alongside the Client, Project Team, the British Museum Security Team and a wide range of stakeholders, including DOCOs, NaCTSO, NPSA, NCSC and CTSA. The Consultant will review project information and undertake independent threat, vulnerability and risk assessments to support delivery of the programme. The appointment will include the following scope over RIBA stages: Develop the Project Security Strategy (RIBA Stage 3 - Spatial Coordination) • Review the completed RIBA Stage 2 design proposals and provide advice on security systems, equipment requirements and layout optimisation, including recommendations on spatial planning and materials selection • Conduct threat, vulnerability and risk assessments, using a methodology based on ISO 31000, to inform the project Security Requirements • Review estate wide security constraints and engage with relevant consultees, including DOCOs, NaCTSO, NPSA, NCSC and CTSA • Develop a project-specific Security Strategy, integrating security measures into the design and coordinating with other Project Strategies including fire and acoustics, in alignment with the Cost Plan • Identify potential locations and space requirements for functional security spaces, outline security rating requirements and produce a Stage 3 report setting out the status of the security design Provide Security Technical Design Advice (RIBA Stage 4) • Maintain an iterative review of the security design throughout RIBA Stage 4 and test the technical, financial and operational viability of the proposals from multiple viewpoints. • Develop detailed design of the security systems, including access control, video surveillance (VSS/CCTV), intruder detection and intercom systems • Provide an initial blast mitigation assessment and advice on measures to protect visitors, staff and collections • Develop and support delivery of a pre-market engagement strategy for security contractors to inform the Procurement Strategy, Master Programme, Cost Plan and Risk Register. • Prepare production information, including specifications and security schematics, to enable tender responses to be obtained from security contractors • Development of emergency procedures, duress and lockdown scenarios to support construction and temporary works phases Procurement Support (RIBA Stage 4) • Support the procurement of packages to deliver the agreed Security Strategy, including pre-qualifying potential security contractors and responding to tender queries • Contribute to definition of Contractor Design Portions for security systems were relevant • Review and contribute to RIBA Stage 4b procurement documentation in line with the agreed Procurement Strategy, including review of technical specifications relevant to the security systems, and participate in tender evaluation and technical adjudication. • If instructed, produce and input into documents required by the local planning authority, including a Crime Impact Assessment, for the discharge of Planning Consent Conditions and Listed Building Consents Construction Support (RIBA Stage 5) • Assist the Contractor's design team in preparing detailed and coordinated production information for the security systems, including drawings, schedules and configuration documents. • Review proposed installation methodologies of the appointed security contractor(s) in line with the Security Strategy, statutory and planning requirements and best practice, and witness commissioning and testing of security systems Security Advice in relation to Handover and Operational Use (RIBA Stage 6&7) • Assist with handover of all security systems documentation, including operating manuals, warranties, maintenance schedules and as-built information, and ensure security equipment is correctly asset-tagged • Assist the Client in establishing performance benchmarks for the security systems, evaluate them periodically once operational, and provide recommendations for optimising the systems based on user feedback and performance data Comprehensive details of all Packages are provided in the tender documents. Due to the confidential/commercially sensitive nature of information that will be included in the associated tender documents we require that interested suppliers enter into a confidentiality agreement before they are given access to the tender pack. A copy of the confidentiality agreement is available by request via email to [email protected]. The terms of the confidentiality agreement are not subject to negotiation. As soon as practical after the receipt of completed confidentiality agreements, interested suppliers will be granted access to the tender documents.
