Notice Title

Repairs to House of Lords Chamber Roof - Main Works

Notice Description

The Corporate Officer of the House of Commons and the Corporate Officer of the House of Lords, acting jointly, invite requests to participate from suitable organisations who wish to tender for a contract for the Repairs to House of Lords Chamber Roof - main works. The scope includes the removal, refurbishment or replacement, and re-installation of cast iron roof components, and in-situ repairs to the supporting structure to the cast iron roof over the House of Lords (HoL) Chamber and adjacent rooms. This will be a Traditional Design (by the existing appointed consultant team) with the successful Contractor taking on design responsibility for the temporary works, scaffold, logistics and mechanical and electrical work. The HoL Chamber roof is the largest single cast iron roof at the Palace of Westminster. In plan the roof is over one thousand square metres, made up of over 5,000 individual external cast iron components. A single cast iron tile can weigh 75kg. A comprehensive overhaul of the HoL Chamber cast iron roof was carried out in 1996 and it was therefore not included in the more recent programme of cast iron roof works. Remedial works were carried out on the roof in 2015 and a survey was undertaken in 2021 which highlighted that the roof was continuing to deteriorate. Whilst temporary measures are in place, the roof now requires complete refurbishment. This project will ensure that the cast iron roof is repaired, mitigating health and safety risks and preventing irreversible heritage damage, and ensure both Houses fulfil their duty of care obligations as custodians of the Grade 1 listed building and part of a UNESCO World Heritage Site. The procurement is following a Competitive Dialogue procedure to enable dialogue on key topics where Contractor input would be beneficial such as scaffold, temporary works, logistics and programme, as well as approach to meeting the cast iron repair works specification. The overall programme for this contract is anticipated to be approximately 3.5 years, and dates are indicative, however these will be tested and confirmed during the dialogue process, taking into account feedback on the implications of, and approach to constraints that will apply. Additional documentation will be available following security clearances for the dialogue stage. Estimated contract value range includes Option X1 inflation to the end of the contract, but excludes VAT and risk/compensation events (NEC4 ECC Option B).
