This project involves a four-phase interior and exterior renovation of Science World including an 11,000 sf interactive exhibit gallery, a family centre stage and an outdoor science park. This project has been designed and developed using a fast track, design build approach, with Heatherbrae providing ongoing costing and construction advice to support ongoing design development and adjustment by the design team to meet a phased and uncertain overall budget. The entire project has been completed in Revit and we have been able to use 3D BIM information to develop estimates.
