Practice Statement:

The designer continues to interface with the selected contractor throughout the construction phase.

Practice Description:

  • Potential safety concerns are resolved more quickly, thereby minimizing subsequent modifications to the project design, costs, and completion.
  • The designer’s inspections of the project during different stages are facilitated.
