India Buildings – BIMLiverpool

Multiple Digital Engineering service streams for a major refurbishment of an existing Grade II* listed building to provide high-quality office accommodation.

Ridge is providing BIM Coordination, BIM Information Management, Geo-spatial and Asset Tagging services, for the owner/operator during pre-contract stages, and for the main contractor in post-contract stages. HMRC as a public sector tenant have a series of requirements for their projects to be delivered using Level 2 BIM principles as per the UK Government’s mandate. The ornate and complex existing building fabric was captured utilising laser scanning technology by the Ridge Geo-spatial team.


Following receipt of the HMRC Employer’s Information Requirements (EIR), our role was to interpret the objectives and agree the processes with the design team through development of the BIM Execution Plan (BEP). In parallel to this, our Geo-spatial team were collecting point-cloud data in order to create accurate Revit models of the existing building for the design team’s use. Ridge deployed a Common Data Environment (CDE) platform during the pre-contract stages before the main contractor introduced their own platform. Ridge also led the development and collation of data deliverables (COBie) through workshop forums, intended to be used by the client team to manage the India Building project through operation stages. In parallel, our Asset Tagging team utilised the COBie data as a register of the assets to which they would be applying tags, and to link the physical asset with the digital information contained within the COBie dataset.

Combining our Digital Engineering expertise in the BIM, Geo-spatial, and Asset Tagging spaces ensured that everything from existing data capture, to development of data deliverables, through to execution of applying unique barcodes to maintainable assets was coordinated. This in turn provides both the owner/operator and tenant with an accurate 3D geometric record of the complex, grade II* listed building, with valuable data attributed to model elements, and barcodes to link physical assets to the COBie dataset.
