What is it called if you start on a project without first finishing the plans?

The term that describes starting on a project without first completing the plans is known as Fast-Track Construction. This approach allows construction to begin on certain aspects of a project even while other aspects are still being designed or planned. The main advantage of Fast-Track Construction is that it can significantly reduce the overall time to completion, as different phases of work can overlap rather than waiting for the entire project design to be finalized.

This method can be particularly beneficial in situations where time is a critical factor, such as in a competitive market or for urgent projects. However, it also requires careful coordination and communication among the involved parties to ensure that ongoing work aligns with evolving designs and that any changes can be managed effectively throughout the construction process.

In contrast, other options like Design-Bid-Build, Phased Construction, and Sequential Building typically follow more traditional pathways where planning is completed before the initiation of construction activities, thereby ensuring that design integrity and project requirements are thoroughly addressed beforehand.
