About Project:

The project involved the construction of two Orthopaedic Theatres as an extension to the original hospital building.  The theatres were located at ground floor level with a first floor plant area containing from which the utilities to below were provided.  The project was delivered using BIM at all stages.

Co-Ordination Considerations

As a BIM project, the construction team were provided with 3D models from design stage which needed to be co-ordinated to a workable and installable level prior to commencement.  Working on behalf of a number of contractors, ENGdoc provided a range of services from the production of BIM documentation for the main contractor to the point cloud scanning of the building for handover.

As well as the day to day co-ordination between trades, practical consideration had to be given as to how services would be accessed for maintenance once the hospital building was occupied and running.

Accurate As Built Drawings

With this is mind, it was critical that the final handover drawings and model accurately reflected what was installed on site, including critical components concealed within the voids such as volume control dampers, fire dampers and valves.

To achieve this, ENGdoc carried out a number of point cloud laser scans at different stages of the project.  Initially following 1st fix to capture above ceiling items which were to be concealed, and finally at 2nd fix to recorded the final locations of services.  This information was then brought into the Revit model which was amended to match the actual installation locations before being issued to the client for record.
