What is the term for the construction process that begins before the completion of contract documents?

Fast-Track Construction refers to a construction process where work begins before the completion of contract documents. This methodology allows various phases of the project to overlap, which can lead to a significant reduction in overall project timelines. By starting construction on certain portions of the project while other sections are still being designed, contractors can expedite the process and deliver the project more quickly than traditional methods that require all contract documents to be finalized before any construction activity begins.

This approach can be particularly advantageous in scenarios where time is critical, such as in public construction projects or for clients with specific deadlines. It demands strong coordination and communication among all parties involved to ensure that design changes do not lead to delays or costly rework.

Other methods mentioned in the options, like Sequential Construction and Design-Bid-Build, typically follow a more linear approach and do not allow for such overlapping of design and construction phases. Similarly, a Turnkey Project, while it can involve a single contractor handling all aspects of the project, typically requires a full design before construction begins. Thus, Fast-Track Construction is distinct in its ability to initiate construction during the design phase, making it the correct term for this construction process.
