A design-build approach bundles design and execution under one contract, aligning budget, schedule and quality from day one. By establishing a detailed BIM model and a Guaranteed Maximum Price as early as the design phase, choices for materials and engineering are balanced on both aesthetics and cost efficiency. Value engineering removes unnecessary luxuries or duplicate functions at an early stage so that the estimate is realistic before the first pile goes into the ground.

During construction, that budget remains transparent through open-book procurement and real-time cost-tracking dashboards; any deviation from scope or price must first be approved. A small, predetermined risk buffer – usually about 5 percent – plus monthly cost-to-complete audits catch unforeseen market fluctuations or delivery issues. Thus, the project ends up exactly within the agreed ceiling amount and with no surprises in the delivery phase.
