In a fixed price or lump sum contract, when can contractors bid on work?

In a fixed price or lump sum contract, contractors can bid on work when they have access to complete drawings as well as partially completed work. This flexibility allows contractors to assess the scope and pricing of a project even when all details have not been finalized.

Complete drawings provide a clear representation of the project, enabling a comprehensive evaluation of the materials, labor, and timelines needed. However, allowing bids on partially completed work can also encourage competitive pricing and more efficient project timelines. This can be particularly advantageous when a project is in progress or when a design may still be in development, as contractors can provide realistic quotes based on their understanding and interpretation of the available information.

In contrast, relying solely on conceptual designs may not provide enough information for a contractor to accurately gauge the resources required, thus making it challenging to provide a satisfactory bid. Additionally, requiring bidding only after contract signing would negate the competitive bidding process and could reduce the overall quality and pricing of contractor offerings.
