Case Study: Arup achieves efficient roof geometry and constructability with Trimble Tekla

Tekla utilized to develop geometry and efficiencies for the roof structure of the Singapore Sports Hub

Arup faced the challenge of designing and delivering the Singapore Sports Hub’s massive free-spanning dome roof, where complex curved steel geometry, model interoperability, and coordination across architecture, structure, and building services had to be managed precisely. Using Trimble’s Tekla software and BIM, Arup developed the roof geometry and optimized the fixed and movable roof design for buildability and efficiency.

Trimble’s Tekla model enabled accurate data sharing with the steel contractor and other project teams, supported clash detection, fabrication documentation, and erection planning, and helped keep the roof steel weight extremely low. The result was a highly efficient 312m-span roof weighing just over 120kg per square meter, with the project earning the BCA BIM Platinum award and “Best Steel Project” at the Tekla Global BIM Awards 2014.
