BIM MODELLING AND DATA COLLECTION
Redevelopment Project team, all the way through to the Facilities Management, Operational, and Clinical teams. Claire Orchard and the team identified an opportunity to retrospectively look at their BIM processes on already completed projects – an example being the construction of the Cancer Centre at Milton Keynes University Hospital, which was completed and opened in 2019. During the centre’s construction, BIM was not fully utilised.
Inefficiencies identified “We quickly realised there were inefficiencies in the way we were working due to the gaps in our current building data,” explained Claire Orchard. “For the Cancer Centre, many of the external project collaborators held the data that we needed in their project Common Data Environment (CDE). Unfortunately, we discovered, some of the data didn’t exist at all. We had a particular example where we needed to replace a glass window in the Cancer Centre, and although we had the specifications of the window, we didn’t have the information we needed on the tint of glass used. Another example was the federation of 3D models between architecture, engineering, and construction (AEC) partners. One of the models had not been federated, and as such, didn’t represent an accurate positioning compared with other models.” These examples demonstrated that
the Trust did not have an ‘as-built’ representation of the Cancer Centre, so Claire Orchard approached Symetri again, this time to help MKUH build up a proof of concept for using Construction Operations Building Information Exchange (COBie) data, and the building of an early digital twin.
Understanding where the ‘gaps’ were MKUH used tools within the Autodesk Construction Cloud to test this proof of concept. “It was important,” Claire Orchard explained, “that we took learnings from the construction of our Cancer Centre to understand where we have gaps and how we can improve our BIM strategy for future projects. We needed to move away from our previous ways of working to embrace technology and data, so that in future we use this strategically to the benefit of all users of the hospital site.” The team used the strategy articulated within their EIR and AIR with the aim of retrospectively building a BIM model of the Cancer Centre using a COBie schema – a standard which defines information for assets that are delivered as part of a facility’s construction, and is used to document the data for the BIM process. “To get the most out of the data that MKUH was harnessing through its new BIM strategy, we quickly realised that the
