Nithya Caleb, the editor of The Construction Specifier, interviews independent specifications consultant Vivian E. Volz, RA, CSI, CCCS, AIA, LEED AP, about the delegated design and design assist processes.
Railing systems are ubiquitous in the built environment, and as such, their appearance is more highly considered than functionality. Minimum loading requirements for railing systems have been part of codes for about as long as these standards have been in existence.
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.
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.
