Commissioning
SCOPE
Letters of Interest, qualifications statements, and SF-254 will be received for
Commissioning Services (MEP & Building Envelope) for the new 80,000 sf Health Science
Education and Simulation Center at the Dallas Campus of Gaston College in Dallas, NC.
The new facility will consist of a stand-alone facility adjacent to the existing David Belk
Canon Building. The project will be constructed by Shelco and delivered via CM at Risk.
Work included but not limited to the following services, and all work shall be performed in
accordance with the project specifications and plans. Note: The Building Envelope
services shall be provided as a subconsultant to the MEP Commissioning services.
SYSTEMS COMMISSIONING SCOPE OF SERVICES (Cxa)
The Commissioning scope of services extends from design through warranty phase. The
objective is to ensure that the Mechanical, Electrical and Plumbing systems of each facility
commissioned have been verified and documented to be complete and to fulfill the
functional performance and maintainability requirements of the designer, building owner,
occupants and building operators prior to building occupancy. Commissioning Services
will include verification that the Owner’s requirements are met throughout the design,
construction, start-up and initial operation/warranty phases along with appropriate
documentation of same.
During the design phase, it will be the Commissioning agent’s responsibility review designs
to ensure the MEP systems meet the Owner’s requirements and to develop detailed
commissioning specifications for the MEP systems for inclusion in the bid documents.
During the construction phase, the Commissioning agent will develop and coordinate the
execution plan for functional testing including observation and documentation of each
system’s performance to ensure systems are functioning in accordance with the contract
documents and Owner’s requirements.
In addition, the Commissioning agent will review O & M manuals for completeness as well
as coordinating and reviewing training on system operation provided to the building
operators to ensure each facility operates as intended. Commissioning Agency should
have at least one team member that is Niagara 4 Certified.
Note: Requirements listed are projected services of the Cxa. Final determination of full
scope of services will be determined with Gaston College and the full Design Team
following the selection process.

and approved submittals. The Cxa shall verify that all approved equipment is in
the proper locations.
• All field connections to the equipment will be verified for proper connection.
• Verify all accessories are installed.
Functional Performance Testing

BAS/EMS graphics (remotely from their office).
(6) The Cxa shall review the BAS/EMS systems remotely and determine if any significant
changes have been made to the systems.
(7) Cxa shall be on site as needed after the field verification phase has started and to
attend the OAC meetings. The Cxa will be expected to facilitate commissioning
efforts during these meetings as well provide an up to date deficiency log listing all
issues and their status. Cxa will review the schedule and verify whether Cxa items
and appropriate durations are included.
(8) The Cxa shall verify airflow for 10% of grilles and diffusers are within tolerance of the
drawings and compare with the test and balance report. If more than 15% of the
tested grilles are outside the tolerance the test and balance company shall
rebalance and another 10% of grilles and diffusers shall be verified (cost to be
charged to contractor).

BUILDING ENVELOPE COMMISSIONING SCOPE OF SERVICES (BECx)
The scope of requested services extends from design through the construction phase with
the objective to ensure the roofing, insulation, vapor barrier, air barrier, through wall
flashing, waterproofing, damproofing, window flashing, and wall cladding systems of each
facility.
Note: Requirements listed are projected services of the BECxa. Final determination of full
scope of services will be determined with Gaston College and the full Design Team
following the selection process.
Design Document Review
The BECxa will perform two (2) total independent third-party reviews of building enclosure
systems and components in project specifications and drawings, one each at
approximately the 90% Design Development progress level and at the 50% Construction
Document level. BECxa to evaluate compatibility of materials & assemblies, continuity of
control layers and appropriateness of building enclosure system designs and verify
compliance with the OPR and BOD. The reviews will focus on building enclosure
components that resist water intrusion including roofing, waterproofing, sealant and
flashings. Review scope does not include a structural evaluation of roofing and cladding
systems and is not intended to discover or report all potential water penetration issues.
Review scope includes evaluation of roofing and cladding systems and is intended to
discover or any potential water penetration issues. Written comments will be listed in
chart, letter form of report or annotations on drawings. Building leakage goal is
<0.10cfm/SF at listed pressure, utilizing fan wall test in-situ as described below.
Submittal and Shop Drawing Review
The BECxa shall review product submittal documents including shop drawings for roofing,
curtain wall, wall cladding, waterproofing, fenestration systems and other building
enclosure related documents as may be required by the contract documents for
compliance with the plan and specifications.
On-Site Meetings
The BECxa shall attend on-site meetings with the project team, including building
enclosure system pre-installation conferences, mock-up meetings, construction progress
meetings, and commissioning team meetings. Mock-Up Testing may be included.
Periodic Inspections
The BECxa shall perform periodic construction observation of building enclosure system
installations and review compliance with the contract documents and OPR and BOD.
BECxa shall issue reports documenting observations and discussions on-site. Eighteen
(18) site visits are anticipated including one visit at substantial completions and one visit at
final completion.
Performance Verification Water Testing – In-Situ
The BECxa shall provide performance verification testing on building enclosure system
installations. Performance verification testing shall include testing installed fenestration
systems for air and water leakage. Air and water leakage tests will be conducted on
approximate 10’ x 10’ areas of fenestration in general accordance with ASTM E783 and
ASTM E1105 and utilizing calibrated spray rack equipment and interior air pressure
chambers. Four (4) pressurized chamber tests are anticipated. Additionally, water leakage
tests will be conducted on approximate 10’ x 20’ areas of fenestration utilizing a monarch
nozzle in general accordance with AAMA 501.2. Two (2) nozzle tests are anticipated.
Air and water leakage tests are to be conducted before interior finishes are installed to
provide direct examination for detection of leaks during the tests and to enable glazing
removal and reinstallation to correction construction deficiencies (if any) in the event of a
failure of the test. Each retest will be billed as an additional test. BECxa shall document,
evaluation and report the testing results and provide suggestions for acceptance or
rejection of fenestration system and/or components.
