latest Unified Facility Guide Specifications (UFGS). The CxC must also be employed regularly
in building commissioning. Generally, the CxC shall be employed by a commissioning firm that
is a first tier subcontractor hired by the construction contractor, and is supported by other
commissioning specialists employed by that firm; however, as determined by the Authority
Having Jurisdiction (AHJ), in consideration of the size, scope, and complexity of the project,
with requisite experience and qualifications, the CxC may be an employee of the prime
construction contractor. The CxC in a Design-Build Acquisition will also assume the
responsibility for the design related commissioning tasks and duties associated with the design
phase of the project. The CxC is required for all projects.
Commissioning Specialist for the Designer (CxD): The CxD is the lead individual on the Design
A/E staff, an employee of a commissioning firm directly contracted by the A/E, or for in-house
projects, can be on the in-house USACE design staff, having expertise in the commissioning
process for facilities of a scope and complexity comparable to the individual project, and is
responsible for the commissioning activities during the design phase. The CxD is required for
Design-Bid-Build (DBB) projects, and during Design-Build (DB) RFP preparation for DB
projects. For projects for which in-house personnel are fulfilling the role as CxD, they may also
be designated as the CxG and continue that role throughout the life of the project. The CxD is
supported by other commissioning specialists/team members as necessary.
Commissioning Specialist for the Government (CxG): The CxG is the lead individual, employed
by the Design and Construction Agent (USACE) or entity directly contracted by the Design and
Construction Agent, but not affiliated with the construction contractor, and is responsible for
government oversight of the commissioning process. The CxG shall have expertise in the
commissioning of facilitates of comparable scope and complexity, and employed regularly in
building commissioning. The CxG is required for all project procurement methods. The CxG is
supported by other commissioning specialists/team members as necessary. For the purpose of
meeting industry’s “enhanced” Cx requirements (i.e. USGBC’s LEED Rating system, EA Credit
3), the CxG is considered the CxA and is the lead individual responsible for government
oversight of the commissioning process.
Commissioning Specialist: The commissioning specialist(s) as a member(s) of the
commissioning team is defined as the individual(s) responsible for supporting the detailed
implementation of the commissioning process executed by the lead specialists, i.e., CxG, CxD
and CxC, to include but not limited to: drafting & completion of checklists, perform test
procedures, record and document test results, and accomplishes other execution of the
Commissioning Process. It is important to recognize that the lead commissioning specialist is
supported by a multi-discipline team, except on very small projects.

commissioning process. The team is composed of USACE Design Manager (DM), USACE
Project Manager (PM), designers (USACE and/or Architect-Engineers), commissioning
specialists (USACE and/or Architect-Engineers - CxG and/or CxD), users (facility, tenant,
