with the RFP requirements, the accepted proposal, and the Design-Build contractors final
design. In order to perform proper commissioning, the HVAC final design must include the
Duct layout and sizing with supporting calculations.
Maximum and minimum air flow at each terminal unit and at each diffuser/grill.
Mechanical Room layout and equipment positioning.
Piping layout and sizing.
Sequence of operation.
Location where TAB and commissioning measurements can and will be taken.
CEGS 15995, entitled COMMISSIONING OF HVAC SYSTEMS, provides detailed information
on how commissioning of HVAC systems can be performed. The extent of commissioning
required in the RFP should be based upon the size of the project and the complexity of the
m. If the project is expected to have HVAC system components in high bay areas or in
attic spaces, the RFP should require reasonable access to these components for routine
maintenance. This access should not require the customer to employ unusual types of
n. Ensure that the design-build RFP, design submittals, and construction activities are
properly coordinated with Corps of Engineers Mandatory Centers of Expertise. ER 1110-1-
8158 lists these Centers of Expertise whose involvement is mandated by HQUSACE. For
example, coordination with the ESS and UMCS Centers of Expertise is critical to ensure
successful integration and implementation of the associated systems and equipment.
o. Consider a requirement to design for future expansion.
