It has been our responsibility to develop the detailed design and ensure that the Stage 3 scheme is translated into a workable, buildable solution. The design incorporates glulam timber beams creating a curved roof form and providing visual interest from within the passenger waiting environment. The roof itself is covered with an extensive sedum system, reinforcing the original concept to provide green space terracing in relation to Chester Cathedral.
The complex geometry of the design means that using Revit is the best way of understanding the design and build challenges for the team. This has been the tool from which the sub-contractors have developed their design packages with Jefferson Sheard in control of the federated model. The project is being delivered to BIM Level 2 with relevant client asset data interpreted within the model.
The main feature of the new interchange - the green expanse on the large sedum roof - provides interest to the surrounding high-rise residential blocks whilst also adding to the sustainability and biodiversity credentials of the building.
