COATINGSPRO MARCH 2017 25 2. Do building envelope specifications need to be integrated with the air barrier specification? Yes, all specification sections for work that interface with the air barrier system must be integrated to estab- lish and maintain the integrity and continuity of the whole building air barrier strategy. For example, cladding and insulation manufacturers/ subcontractors need to know about air barrier manufacturer require- ments for penetration treatments, adhesive compatibilities, etc. Lack of an integrated specification to assist in contractor coordination may lead to inadequate substrate installation, incompatibilities in product selection, or inadequacies in the installation, all of which can affect the final perfor- mance of the air barrier. 3. W hat strategies can be implemented in the project specification to facilitate the CM/ GC's ability to enforce specified installation instructions and to ensure compliance with the specified performance criteria before covering the air barrier with an exterior cladding? Assurance that the air barrier system will meet the required field perfor- mance starts with a quality set of details and coordinated technical speci- fications, including the ABA A QAP. is can help place the GC in the best position to ensure a successful instal- lation. However, a number of strategies can also be employed in the "Quality Requirements" specification (Section 014000) to ensure coordination and verification of the required field performance of the air barrier. ese strategies include: 1. List responsibilities for each member of the construction team (e.g., owner, architect, CM, GC, building enclosure commissioning agent [CxA], subcontractors, manufac- turers, and independent testing agencies). 2. Require the CM/GC to run a building enclosure coordination preconstruction meeting attended by the architect, third-party consul- tant, air barrier manufacturer, installer, and onsite representatives of trades that will interface with the air barrier material. 3. State the requirements for stand-alone or in-place approved mockups to demonstrate accept- able installations of the air barrier that can be referenced throughout the project for comparison. 4.
