Recent pressures have caused responsibility for many design solutions to be transferred to the constructor, as mentioned in Part 1 and Part 2 of this series. To properly complete deferred design, a solid understanding of regulations surrounding shop drawings, specifications, submittals, and other types of documentation is necessary.
The construction community has identified the need for explicit communication to contractors from architectural and engineering firms, clearly and completely describing design requirements presented within specifications that do not form a part of standard services for engineering and design.
It is incumbent on all parties to verify roofing systems are installed in accordance with the manufacturer’s code compliance report. Any conflicts between the manufacturer’s installation instructions and the reports should also be identified and discussed among the project team.
This article is published in two parts. The first part deals with identification of issues and concerns in communicating the need for design solutions during construction. The second part deals with different approaches to describing how to manage the deferred design process. Both articles draw attention to the “elephant” in the room and issues causing disruption and disagreements in executing this requirement.
