AIR BARRIER SYSTEM COORDINATION
PART 1 - GENERAL
1.1 RELATED DOCUMENTS
A. Drawings and general provisions of the Contract, including General and Supplementary
Conditions and Division 01 Specification Sections, apply to this Section.
1.2 SUMMARY
A. Section includes administrative and procedural requirements for accomplishing an airtight
building enclosure that controls infiltration or exfiltration of air.
1. The airtight components of the building enclosure and the joints, junctures and transitions
between materials, products, and assemblies forming the air-tightness of the building
enclosure are called “the air barrier system.” Services include coordination between the
trades, the proper scheduling and sequencing of the work, preconstruction meetings,
inspections, tests, and related actions, including reports performed by Contractor, by
independent agencies, and by governing authorities. They do not include contract
enforcement activities performed by Architect.
2. The Contractor shall ensure that the intent of constructing the building enclosure with a
continuous air barrier system to control air leakage into, or out of the conditioned space is
achieved. The air barrier system shall have the following characteristics:
a. It must be continuous, with all joints sealed.
b. It must be structurally supported to withstand positive and negative air pressures
applied to the building enclosure.
c. Connection shall be made between:
1) Foundation and walls.
2) Walls and windows or doors.
3) Different wall systems.
4) Wall and roof.
5) Wall and roof over unconditioned space.
6) Walls, floor and roof across construction, control and expansion joints.
7) Walls, floors and roof to utility, pipe and duct penetrations.
3. Air Barrier Penetrations: All penetrations of the air barrier and paths of air infiltration /
exfiltration shall be sealed.
B. Inspection and testing services are required to verify compliance with requirements specified or
indicated. These services do not relieve Contractor of responsibility for compliance with
Contract Document requirements.
C. Requirements of this Section relate to the coordination between subcontractors required to
provide an airtight building enclosure, customized fabrication and installation procedures, not
production of standard products.
1. Continuity of the air barrier materials and products with joints to provide assemblies.
Continuity of all the enclosure assemblies with joints and transition materials to provide a
whole building air barrier system.
2. Specific quality-control requirements for individual construction activities are specified in
the sections of the specifications. Requirements in those sections may also cover

production of standard products. It is the Contractor’s responsibility to ensure that each
subcontractor is adequately and satisfactorily performing the quality assurance
documentation, tests and procedures required by each section.
3. Specified inspections, tests, and related actions do not limit Contractor's quality-control
procedures that facilitate compliance with Contract Document requirements.
4. Requirements for Contractor to provide an airtight building enclosure is not limited by
quality-control services required by Architect, Owner, or authorities having jurisdiction
and are not limited by provisions of this section.

1.3 RESPONSIBILITIES
A. Contractor Responsibilities: Contractor shall provide coordination of the trades, and the
sequence of construction to ensure continuity of the air barrier system joints, junctures and
transitions between materials and assemblies of materials and products, from substructure to
walls to roof. Provide quality assurance procedures, testing and verification as specified
herein. Facilitate inspections, tests, and other quality-control services specified elsewhere in
the Contract Documents and required by authorities having jurisdiction or by the Owner. Costs
for these services are included in the Contract Sum.
1. Organize preconstruction meetings between the trades involved in the whole building’s
air barrier system to discuss where each trade begins and ends and the responsibility
and sequence of installation of all the air-tight joints, junctures, and transitions between
materials, products and assemblies of products specified in the different sections, to be
installed by the different trades.
2. Build a mock-up before proceeding with the work, satisfactory to the Architect, of each
air-tight joint type, juncture, and transition between products, materials and assemblies.
B. Associated Services: Cooperate with agencies performing required inspections, tests, and
similar services, and provide reasonable auxiliary services as requested. Notify the agency
sufficiently in advance of operations to permit assignment of personnel. Auxiliary services
required include, but are not limited to, the following:
1. Provide access to the Work.
2. Furnish incidental labor and facilities necessary to facilitate inspections and tests.
