Design-Build (Turnkey)
Quick Definition
"A single-contract construction model where one firm handles both design and execution, streamlining accountability and project timelines."
A project delivery method where the Employer enters into a single contract with one entity (the Contractor) to provide both the design and the construction of the project. Unlike the traditional "Design-Bid-Build" model, the Contractor is responsible for the entire project lifecycle, from architectural concepts to final commissioning. This model is often used for complex infrastructure or projects where speed and cost-certainty are prioritized.
