Kier will initially build the centre as part of a much wider development deal to deliver 750,000 sq ft of offices and homes at the 20 acre site.
The deal, which still has to be officially confirmed, saw Kier beat off rival bids from a Vinci in joint venture with Wrenbridge, Orbit Developments and Burntwood.
As part of the deal Kier will also refurbish and re-let Siemens exiting headquarters.
