Quality Control in Construction: Submittal Review Process (Part 2 of 5)
December 17th, 2013
Thorough submittal review is one element of our Quality Control Program. Submittal reviews enable us to verify and correct dimensions and product compatibility as part of a system, and confirm that products will be supplied in compliance with the specifications before a material problem can impact the construction schedule or quality of the project. It enables us to make corrections before a material or product is even ordered. Our teams take the time to review every submittal; we do not just pass them along to the architect or engineer with the infamous rubber stamp.
On a recent project, our careful review of submittals uncovered a significant problem with the roof design. Incompatible materials were specified; the metal decking could be corroded by contact with the fire retardant treated plywood (FRT) that was scheduled to be installed directly on top of the metal decking. At temperatures greater than 150 degrees, which happens easily within the roof system on a hot summer day, FRT that has been exposed to moisture emits gasses that are known to corrode metal decking. In one case study where this happened (not built by CEF), a school needed a complete roof replacement after only nine years. In our case, the addition of Builder’s Paper on top of the FRT to provide a moisture barrier was sufficient to solve the problem.
Without the submittal review process, this issue would not have been discovered until the roof was being installed – if it was discovered at all – which would have caused, at minimum, a schedule delay, but possibly could have resulted in a future roof failure.
We enjoy discovering and solving potential problems during submittal reviews, before work is put in place. Some contractors rubber stamp their submittals in order to reduce staffing costs…is that the type of quality control you expect?
Stay tuned for part three of this five part series, which will cover the importance of producing mock-ups!
