Air and vapor barriers and waterproofing are Division 07 envelope scopes with their own materials and testing, and a subcontractor that does not read the package is pricing the wrong system.
What these scopes set
Air and vapor barriers and waterproofing under Division 07 protect the building envelope from air, moisture, and water, with sheet and fluid applied membranes, below grade waterproofing, and continuity at transitions. The package sets the materials, the detailing at transitions, and the testing the sub must provide.
Why envelope scope is easy to misprice
The membrane types, the transition detailing, and the testing sit in the Division 07 specifications and the wall sections, not the title. A sub that misreads the system or the detailing carries the wrong material and labor into the bid.
How an AI bid agent reads envelope packages
An AI bid agent reads each Division 07 package, identifies the air and vapor barrier and waterproofing scope, and surfaces the materials, the detailing, and the testing that drive the work. The sub prices the actual system.
You can see how the agent reads an envelope package in our AI bid agent demo for specialty trade contractors. It pulls the air and vapor barrier and waterproofing scope so the envelope work is priced.
