Major British property development company, Hammerson, awarded ISG the project to strip-out and refit seven floors of its 25-storey office building located at 99 Bishopsgate in the City of London. 

99 Bishopsgate is a 26 storey, reinforced concrete tower block, located on a prominent site within the Bishopsgate area, London. Constructed in 1976, the building has been refurbished in response to the growing demand for centrally located, ‘high spec’ commercial office space.


The project

Valued at £8.9m and comprising over 170,000 sq ft, the project entailed stripping out the existing interior. The project was two fold. The first stage involved the complete strip out of existing partitions, doors, joinery and Cat A, followed by a Grade A fit out.

The refurbishment extended across floors one through to six, 20 and 21, the ground floor/reception area and toilet facilities. The floors were returned to Cat A in readiness for Hammerson to re-let in April 2012. The project also entailed significant Mechanical & Electrical works including the refurbishment of air handling units, new fan coil units and chilled water risers.


The added value

A saving of £15,000 was achieved by adopting waste reduction measures detailed in Site Waste Management Plans (SWMP). Prefabricated components provided programme efficiencies and site waste reductions. The project surpassed the target for waste to landfill by 18%.

Operational water demands were reduced through the installation of water efficient sanitary ware. ISG reduced life-cycle maintenance costs through the implementation of durability measures. The refurbishment received BREEAM ‘Excellent’ (2008) rating.
