A330 Multi-Role Tanker Transport Hangar

As a net-positive energy building, A330 Multi-Role Tanker Transport (MRTT) Hangar can generate 30 per cent more electricity than it consumes. For this energy efficiency, Singapore’s Building and Construction Authority awarded it a Green Mark Platinum certification.

The civil and structural engineer employed a sophisticated and robust structural system for the project. To achieve a clear span of up to 90 metres and commit to the lower tonnage of the roof, the engineer used a modular steel truss system supported on laced strut columns. This allowed for a large column-free span without compromising the robustness.

During construction, working space and height were constrained by the adjacent buildings as well as the restrictions from the Civil Aviation Authority of Singapore. As it was not feasible to mobilise a tower crane, the engineer and contractor teamed up with a jacking specialist.
