World Business Centre 4, Heathrow
WBC4 is the latest 4 storey high-tech office building at Heathrow World Business Centre which provides 85,000 sq ft of CAT A office space and has been pre-let to airport technology group Amadeus.
A structural steelwork framed solution for the superstructure enabled the team to meet the required programme, this was achieved by the steel frame while the basement in-situ reinforced frame was being constructed, thus enabling the frame be installed in a following sequence as soon as elements of the ground floor were sufficiently cured.
The choice of steel also enabled the team to consider a value engineered approach to the foundations. All the adjacent WBC buildings were constructed on piled foundations and the original site investigation recommended a similar approach for this structure. However, due to the teams’ experience of the area, having completed several buildings in the vicinity they believed a more cost-efficient raft solution was possible. Following further geotechnical assessment, we were able to achieve a raft foundation which can easily accommodate a four storey framed.
Constructed around a regular 9m × 7.5m pattern, the structural steel solution has allowed the team to meet the client’s requirements for a spacious and open office, with minimal impact from the frame.
The steel frame is derived from bays are positioned within the two central, as well as action the floors.
