Excavator Project Owner Designer

Practice Statement:

Once a project design is completed, the designer participates in the prebid/bid process.

Practice Description:

The designer’s continuing involvement during the prebid/bid phase with the potential contractor(s) allows for more effective communications between all parties. The designer can assess whether the interested bidders have the expertise needed and the correct understanding of the intended design.


  • By providing quality assurance, this practice minimizes potential safety concerns and delays to project completion.
  • The designer would have the opportunity to relay information not readily shown on the plans, such as accommodations of facility adjustments required to construct the project.
