    Brief

    The City of London Corporation invites tenders for fire safety and compliance works at two residential properties: Harman Close in Southwark (39 bedsits, 8 one-bedroom and 1 two-bedroom flat) and Iselden House in Islington (76 flats including 33 sheltered units). Current fire alarm systems have communication failures between smoke detectors and warden call systems, requiring temporary waking watches at both sites. The scope of works includes: replacement of existing fire alarm systems with AICO LD1 systems; upgrading warden call systems to Tynetec Advent XT2 (or similar approved alternative) compatible with digital switchover in 2027; installation of AICO environmental sensors in all dwellings; installation of new mechanical extraction systems in kitchens and bathrooms (subject to survey); and removal of redundant cabling in communal areas to enable fire door installation. Works are subject to condition survey results. Contractors should be experienced in fire safety compliance, residential building upgrades, and system integration in occupied housing blocks.
