Kier was the main contractor for this project. The contractor implemented BIMXtra, which was their own BIM management system to increase collaboration and integration within the team. The BIM software is a CDE, which consolidates information and data via a cloud based subscription service. Kier provided BIMXtra software free of charge in this project, which eliminated the need for expensive servers and systems. In BIMXtra, all information of the project was used for clash detection and coordination. Information from the BIM model was available directly to all subcontractors and fabricators for costing in an organized manner, which reduced double pricing or missing tasks.
Structural design changes were also done by BIM modeling. Structural engineers found out that the steel beams that were supporting the edge protection were not enough. They had to amend the design and construction process by fabricating the edge protection to be pre-installed to the steel beams before erection. Luckily, this was planned out during the design stage to avoid abortive works during construction.
