Construction Documentation

Teams have to provide a representative set of construction document contents that may be used for review with designers, trades, suppliers, fabricators, and purchasers.

Construction details are important for clear and precise communication to the trades (and others responsible for reviewing or implementing the design), as well as for technical analysis of the design. Details clarify complex design elements. They also should be provided where there are potential problems in construction, which often occur at transitions or discontinuities in control layers (e.g., water, air, thermal, vapor). The details provided would use 2D, 3D or assembly drawings, as needed, to avoid ambiguity or confusion. Typical examples of potential problem areas include the moisture control, minimizing thermal bypass, and thermal bridging.
