Drawing proper construction details requires understanding building technology; so does identifying conflicts between the construction documents and the way things are being built onsite. Unfortunately, while knowledge of building technology is an important part of the practice of architecture, it’s an area in which many of today’s young designers are weak.
We hear a lot about new high-performance technologies in buildings, but many design firms have lost the basic knowledge about detailing foundation, roof, and exterior wall assemblies to meet minimum code requirements. Without understanding basic building technology, an architect cannot properly prepare construction documents for submittal to the authorities having jurisdiction (AHJs) to obtain a building permit. Without understanding basic building technology, an architect cannot demonstrate a design’s constructability or its compliance with codes.
Construction documents for all buildings shall describe the exterior wall envelope in sufficient detail to determine compliance with this code. The construction documents shall provide details of the exterior wall envelope as required, including flashing, intersections with dissimilar materials, corners, end details, control joints, intersections at roof, eaves or parapets, means of drainage, water-resistive membrane, and details around openings ?2009 International Building Code (IBC), Chapter 1, 107.2.4 (“Exterior Wall Envelope”)
