How does a design-build entity generally approach cost estimating?

A design-build entity approaches cost estimating by utilizing integrated teams during both the design and construction phases. This method allows for collaboration among architects, engineers, and contractors from the onset, ensuring that cost considerations are factored into the design choices being made. By working together as a cohesive unit, the team can efficiently assess the implications of design decisions on costs, identify potential savings, and optimize resource allocation. This integrated approach not only enhances communication but also fosters a holistic understanding of the project, resulting in more accurate and reliable cost estimates compared to methods that rely on isolated efforts or historical data alone.

In contrast, the options involving historical data, separate teams, or outsourcing do not promote the same level of collaboration and real-time problem solving that integrated teams do. Each of those methods presents potential limitations in accuracy, responsiveness, and overall project alignment.
