Mace has beaten off competition from Interior/Exterior to win a £90m construction management deal to build two additions to a development next to City Hall in Southwark, south London.

This follows the firm’s appointment on a £100m 24-storey office block in Lime Street in the City for developer British Land.

Mace will begin work on the two Foster and Partner-designed office blocks on the More London site in the new year.

The first 10-storey block will house law firm Norton Rose. It will take up 28,000 m2 of a 45,500 m2 plot. It is likely to cost £62m to build, and Norton Rose is due to occupy the space in 2007.

The second office will house fellow lawyer Lawrence Graham. The construction cost is likely to be £28m.

n Contractors are lining up to bid for another Foster and Partners office scheme in Manchester for developer Allied London.

The £40m job will be an addition to the Spinningfields development in the city centre. Bidders are likely to include Bovis Lend Lease, Interior/Exterior, Carillion and Amec.
