Black Raven Court - Remedial Works

About

The City of London Corporation (the City) invites Tenders for the provision of Balcony remedial works at Black Raven Court Black Raven Court is part of the CoLPAI development, which included a refurbishment of an existing school and construction of a new 14-storey tower block of residential social housing.

The school is open and operational but the tower block (Black Raven Court) is mostly complete, with exception of the cladding replacement, for which this tender is related to.

It was always part of the Employer's Requirements to achieve an LABC Social Housing warranty on the tower block; the existing cladding system (Fablite) contains the use of a backing board made out of Magnesium Oxide (MgO).

When excessive moisture infiltrates this board, it can weep chloride, which potentially corrodes surrounding fixings.

As a result, LABC do not warrant buildings which use this board and the client needs to replace the cladding system to one which does not use MgO board to achieve the LABC warranty.

The estimated contract value given is for the full duration of the contract including the maximum possible extensions.

The estimated annual contract value is therefore £2,000,000.00.
