Due to the control we have over design and scope, it is comparatively easy to provide the client with a fixed construction cost early in the project. As constructors, our costing is based on facts rather than assumptions. The cost of the 'unknowns' is minimal. Constructibility assessment and value engineering allow us as a Design-Build team to evaluate alternative materials and building technology to rationalize costs and provide the best-designed value for the money. The greatest saving is in the elimination of layers of markups of contractors and sub-contractors in traditional Design-Bid-Build. Instead, we employ a transparent system of consistent, scientific cost analysis that is open to client audit and scrutiny.
