General Contractor?s Guide for Constructing & Sealing Access Floor Air Plenums
Plenum integrity is crucial for the effective operation of an underfloor air delivery (UFAD) system. The general contractor (GC) is responsible for ensuring that all subcontractors adhere to the sealing requirements specified by the architect to maintain plenum integrity.
Key Recommendations
- Design: Review project specifications and construction details with the architect before issuing construction documents.
- Pre-Bid Meeting: Inform all subcontractors of the plenum sealing requirements and mock-up needs.
- Pre-Construction: Reaffirm plenum sealing requirements for each division in a pre-construction meeting.
- Mock-up: Construct and test a mock-up that reflects actual building conditions related to the UFAD system.
- Quality Inspections: Ensure subcontractors address any issues identified during inspections before access floor installation.
General Contractor Guidelines
The GC should ensure the following actions are completed:
- Pre-Bid Meetings: Use CSI specifications and plenum details to solicit bids and inform divisions about mock-up requirements.
- Pre-Construction Meetings: Reaffirm the importance of plenum sealing integrity and ensure contractors have the necessary drawings and specifications.
- Plenum Mockup and Testing: Coordinate the construction of an on-site access floor plenum mockup for inspection and air leakage testing.
- Auditor Coordination: Work with an independent quality auditor to verify compliance with specifications and drawing details.
- Testing: Conduct air leakage tests on the mock-up and finished plenum to meet project requirements.
- Remediation: Ensure subcontractors address any issues identified during inspections and testing.
Plenum Inspections & Reporting
A checklist for inspections includes verifying the sealing of various structures, seams, penetrations, and openings. Inspections should be coordinated with the GC and conducted throughout the construction process.
