This week, UrbanToronto is introducing a new feature cross-posted from our sister site, SkyriseCities. The weekly "Explainer" series provides an overview of the terms used in the architecture, design, construction, and real estate industries. Ever wondered about the difference between "curtain wall" and "window wall?" And what exactly is a "mullion," or an "architect of record?" You're not alone.
Although these terms—and others like them—are frequently used here on UrbanToronto, they can sometimes be difficult to understand for people outside these industries (including us writers). To help our readers get a better understanding of industry-specific terminology, the explainers offer a breakdown of each term's meanings. Along the way, there's lots to learn about construction, design, and development.
Published each Wednesday, our new feature kicks off with an explanation of the term "architect of record."
When a development application or building permit for a new structure is submitted to a municipality, the architect listed in the associated documents may not be the main architect on the project. Rather, the firm listed on the permit is known as the architect of record. According to the National Council of Architectural Registration Boards (NCARB) in the United States, the architect of record is ultimately in control of the project and must ensure all safety requirements are adhered to during the course of construction.
