43 4 5 Exact coordination between OSM steel frame and opening in external wall to brick dimensions Environmental performance of external building fabric established early in design stage with confi dence using architectural model content as basis for analysis 6 7 Availability of 3D views within construction documentation improves communication of the detail design intent during procurement and construction Using DSfMA has benefi ts for customers in that they can visualise what the home will look like Integrated modelling process and collaborative approach meant team could react quickly to changes steel framed components as shown above. Using BIM the fabricator was able to resolve spatial ‘clashes’ prior to site. The key to success was collaboration and integration of the supply chain team early in the design process. The fi rst two-storey units were built in seven days as it was critical that occupants could move in quickly. Zone specifi c colour-coded sections and BIM coordinated just-in-time delivery made this possible. Offsite manufacture and the digital advancement taking place in the construction industry presents an exciting time for house building, and one that should drive benefi t for consumers too.
