Case Study — Industrial & Manufacturing EV Battery Test Facility, Gaydon

Quantity Surveyor for a £20.3m electric vehicle battery test facility at Gaydon for a global automotive manufacturer, a highly technical building designed to withstand destructive testing of live batteries.

The challenge

A building engineered to contain the worst case

Steel-framed battery test facility building and plant area, Gaydon

A global automotive manufacturer needed a dedicated facility to test electric vehicle batteries to destruction, including drop, submersion and vibration testing of live battery packs. The building had to withstand a possible battery explosion, with test cells built from twin-wall precast and in-situ concrete, and a large basement of seismic blocks on air bags to isolate vibration.

It was delivered on an occupied site, alongside the client’s own direct contractors installing high-value process equipment, which demanded careful coordination of design responsibility and cost.

Delivered by Ollie Thompson MRICS in a previous role at Mace.
