The construction documents must provide details of the exterior wall envelope, including which of the following?

The exterior wall envelope of a building is a critical component designed to protect the structure from environmental elements such as water, wind, and thermal fluctuations. The construction documents must include comprehensive details regarding elements that contribute to the integrity and durability of the wall assembly.

Including flashing is essential, as it serves to redirect water away from critical areas, preventing moisture intrusion that could lead to structural damage or mold growth. Proper flashing design helps ensure that water does not penetrate the wall system, especially around windows, doors, and other penetrations.

Means of drainage is also a vital aspect to detail in the construction documents. Effective drainage systems within the wall assembly ensure that any water that penetrates the exterior layer can be efficiently drained away. This prevents water accumulation that can compromise the effectiveness of waterproofing measures and lead to deterioration over time.

Lastly, the water-resistive membrane provides a barrier against moisture infiltration, acting as a primary defense against rain and water vapor. This membrane is crucial in helping to maintain the building's envelope and contributing to the overall energy efficiency and lifespan of the structure.

By including all of these elements—flashing, means of drainage, and the water-resistive membrane—in the construction documents, the design promotes a comprehensive approach to moisture management, ensuring
