Lot 1: The Palace of Westminster, which includes House of Lords (HoL) Chamber is an internationally important heritage asset acknowledged in its Grade I listed building designation, and inclusion in a UNESCO World Heritage Site along with Westminster Abbey and St Margaret’s Church. <br/><br/>UK Parliament is looking to tender for the removal, refurbishment or replacement, and re-installation of cast iron roof components, and in-situ repairs to the supporting structure of a large cast iron roof. This notice relates to the Contracting Authority’s intention to appoint a Principal Contractor under a Traditional single stage NEC4 ECC Option B contract (with secondary clauses and client amendments - z clauses). The contract will also include Contractor design of temporary works, scaffold and logistics.<br/><br/>The roof over the HoL Chamber and adjacent areas 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 this cast iron roof was carried out in 1996 and it was therefore not included in the subsequent programme of cast iron roof works. <br/><br/>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, with failure of the paint system and jointing both internally and externally, potentially allowing water ingress in these areas. 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. It will also 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<br/><br/>UK Parliament is looking for contractors with demonstrable cast iron roof specialist experience that have the capacity, capability and expertise to carry out the works which comprise of the following:<br/>• Refurbishment & repair of damaged elements of the historic roof structure and components including refurbishment of the cast iron tiles and wrought iron structure,<br/>• Application of an anti-corrosion treatment<br/>• Technical examination of tiles for damage<br/>• Temporary relocation of services (security cameras, lightening protection system) off roof areas and reinstallation on completion of the works. <br/>• Removal of the tiles and other external components and repair and treat them in factory conditions away from site<br/>• Fabricating new replacement cast iron roof components that cannot be repaired. <br/>• Following remedial works, tiles will be returned and reinstated. <br/>• Scaffolding which will be an important part of the works and must provide a weather tight and secure temporary roof<br/>• Design of temporary works, logistics setup and scaffolding taking into account of close proximity of other projects.<br/>• Temporary protection of heritage and artwork <br/>• Full protection will also be required internally within the roof space. <br/>• Removal of asbestos from roof voids (where practical and cost effective)<br/>• Removal of redundant services from roof voids (where practical and cost effective)<br/>• Limited, urgent Health & Safety risk mitigation stone repairs<br/>• Downpipe repairs<br/>• Repair of abutting flat asphalt roofs<br/>• Installation of safe access system<br/><br/>Further details and indicative programme can be found in the RFI (see section II.2.14) Additional Information below for details of how to access).<br/><br/>This PIN seeks to update market engagement previously undertaken in late 2021/early 2022, to further explore and understand the market and engage with suppliers who may be able to undertake the work.
