PCMS have worked alongside NG Bailey to provide BIM Services on the Northern Line Extension tunnel, operating from concept through to as-built. This was an MEP project, including the modelling of all bracketry and support railings, tunnel wide. Using BIM tools such as AECOsim Building Designer we were able to coordinate with the new tunnel point cloud architecture. Alongside FLO, we implemented Projectwise (CDE) collaboration and workflow across all model and drawing delivery.
