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 paint... > [Read full procurement scope and specification on Tenderline](https://tenderline.uk/tenders/british-museum-round-reading-room-roof-oculus-works-ocds-h6vhtk-06de58) ## Lots (1) ### Lot 1: Untitled lot - **Lot id:** `1` - **Status:** active - **CPV codes:** 45212313, 45260000, 45350000, 45441000 - **Delivery regions:** UKI - **Delivery countries in notice:** GB - **Estimated Value:** £9,000,000 - **Contract Period:** 04/01/2027 to 31/03/2028 ## Provenance and Official Sources - **Official Notice:** [Find a Tender notice](/out?url=https%3A%2F%2Fwww.find-tender.service.gov.uk%2FNotice%2F080571-2026) - **Last Source Update:** 2026-09-24T15:01:30.000Z - **This document generated:** 2026-10-26T08:54:34.369Z - **Machine API:** https://tenderline.uk/api/public/tenders/ocds-h6vhtk-06de58
