St. Lawrence Jewry External (Phase 1) Works

Tender description

The City of London Corporation (the City) invites Tenders for the provision of St. Lawrence Jewry Church Refurbishment Works. The project being tendered marks the largest phase of work to the building since the Cecil Brown rebuilding and will ensure the safeguarding and enjoyment of the Church for future generations. Many of the finishes to roofs, gutters, cupola and spire date from 1957 and are therefore towards the end of their service life, evidenced by the water ingress that has been an increasing problem in recent years. The surviving Wren masonry suffers from heavy carbon staining and discoloration along with a pattern of defects known as "corrosion jacking", caused by concealed iron cramps rusting, expanding and subsequently splitting and cracking the stonework. The project seeks to return the Church to a sound state of repair and improve the presentation of the historic building within the prominent backdrop of Guildhall. • Sensitive cleaning and repair of the masonry elevations and tower, including conservation cleaning of highly enriched, carved stonework. • Re-roofing and thermal upgrading of the lead covered Nave. The Nave roof is also to be structurally upgraded to permit additional loading. • Re-roofing of all flat roofs including the Commonwealth Chapel, Vicarage apartment and flat roof to the south-west of the tower. • Repairs to the timber framed, lead-clad cupola and spire. • Replacement of lead gutters and downpipes. • Overhaul, cleaning and repair of all stained and plain glass windows. • Replacement of lightning protection. • Repair and structural strengthening of decorative fibrous plaster ceilings. • Other ad hoc works
