On some projects, it is prudent for the roof designer to have their specifications and drawings peer reviewed by someone knowledgeable of the specified system. Peer review should be considered for office buildings with very valuable contents or operations, projects where the cost of the roofing work is very substantial, complex, or unusual projects, and those projects where the designer believes his or her expertise is lacking.
CONSTRUCTION CONTRACT ADMINISTRATION
During construction contract administration, the roof designer or the entity responsible for construction contract administration has several important tasks. These tasks need to be executed regardless of project size or location, although the amount of time devoted to the tasks will be dependent upon the roof size and other factors.
The following topics are discussed in this subsection:
- Submittal Review
- Pre-Roofing Conference
- Field Observations
- Non-Destructive Evaluation (NDE)
- Project Close-Out
It is incumbent upon the reviewer to be thorough, diligent, and cautious during the submittal review process. (Note: In complex or unusual projects, or where the reviewer lacks sufficient expertise to adequately review the submittals, a professional roof consultant who is knowledgeable about the particular roof system should be retained to review the submittals.) The reviewer should:
- Verify that all of the specified submittals are received and approved.
- If a submittal item is to be resubmitted, make sure that it is. Sometimes items to be resubmitted are forgotten about. These items often become problems.
- Be cautious in approving materials, systems, and details that are not in accordance with the contract documents. Minor changes may affect code compliance or roof system performance.
