BIM facilitation of a major government project in the Canterbury rebuild.
This case study demonstrates how Building Information Modelling (BIM) was used to co-ordinate the construction of the largest multi-agency, government co-location project in New Zealand’s history – the Christchurch Justice and Emergency Services Precinct (CJESP), led by the Ministry of Justice.
‘The Precinct’ was one of the Government’s anchor projects for the Christchurch rebuild, to bring together all justice and emergency services agencies for Canterbury into one purpose-built, leading-edge facility. The Ministry of Justice made it a mandatory requirement that the lead contractor use BIM to assist the Precinct’s construction to ensure effective cost and design management.
BIM proved to be an invaluable co-ordination tool on this massive construction project which involved 10 different disciplines and up to 500 people.
The project BIM manager worked with the design management team to pull the individual detailed design models together into a single 3D federated model. The detailed design models and federated model were then shared with subcontractor teams as the basis for preparing their fabrication models. The entire design team worked together in this 3D environment before the build, co-ordinating their efforts – sharing and collaborating as a virtual project team.
BIM also created many unforeseen opportunities for the project, made planning the location of building services easier and allowed the attribution of metadata to plans and equipment to assist with future maintenance.
