URS Corporation was appointed as the MEP designer for the comprehensive renovation of the University Arms Hotel in Cambridge in late 2013. The proposal created by architect John Simpson was to transform the hotel’s disparate buildings into a cohesively designed, landmark hotel.
As a key member of the design team, URS was required to use Revit for the production of their design information. With limited knowledge at this point of using BIM, URS employed Cadnet to deliver the Stage D and subsequently Stage E design models in summer 2014.
The MEP model was built from traditionally authored 2D design drawings, red line mark ups and sketched details. The information was authored in Revit and cached in Navisworks for review by internal and client team members.
Cadnet highlighted potential issues within the model to URS with the use of clash detection reports.
These enabled the URS designers to quickly pinpoint the problem area, consider a solution and communicate the changes back to Cadnet for remodelling. As the project developed the Stage D information was migrated to a more detailed Stage E format.
The detailed 3D model provided the design team with an insight into the engineering issues that could not have been achieved in a 2D working environment. This included the impact of service sizes and routes together with the knowledge gained from being able to navigate the 3D environment. For example the proposed height of ductwork as illustrated above.
The project also provided the URS team with an introduction to the delivery of a complete 3D MEP model in a Revit environment within a tight timeframe. When the Stage E model and Cadnet’s commission was complete URS took over further development of the model towards Stage F and the final drawing production.
