Following on from our successful project delivery for the Hong Kong International Airport Authority (HKIAA) in 2021, we secured a second contract in August 2022, to assist with the redevelopment and expansion of the ‘Asia World Expo’, Asia’s leading convention, exhibition and events venue.

Commissioned directly, once again, by HKIAA, as part of the project team, D4S worked alongside Arup and architect Ronald Lu & Partners, to design the large roofing structure for the arena.

The Solution

Working collaboratively with the design team, D4S developed a fully federated BIM model to LOD400 specification, to be included within the contractors tender package to ensure accurate pricing from the steelwork contractors.

The structure consists of a primary frame (trusses, ties, braces), a secondary system (service access ditches & cladding support rafters) and a lower level walkway system. D4S were also contracted to develop a LOD300 specification model for the cladding and balustrading to the main roof and access ditches. This model was produced to show design intent to prospective clients with the final design to be completed by the contract after award.

Delivery Impact

As with our previous role on the HKIAA terminal 2 roofing structure, taking a digital asset led approach, enabled the client to effectively manage, resource and price the project before reaching the construction phase, essentially paving the way for more efficient delivery and timescale accuracy.

The project team worked across Hong Kong, Mexico, Greece and the UK, so effective use of Trimble Connect technology, enhance project collaboration and the fast moving nature of the project.

 

Trimble Connect

Using Trimble Connect as the main tool for collaboration, D4S kept a live model on Trimble Connect for all project stakeholders to view and access at any time. All RFIs and queries were raised using the Trimble Connect “To Do” procedure which enabled both the D4S team and engineering team at Arup to track progress of all queries which on a structure this size, totalled in excess of 850 RFIs, often with 100+ open at one time. The use of this system enabled the use of live model views and annotation to enhance information transfer between teams across the different time zones.
