Regulation
No. 1110-345-723 31 March 2017
Engineering and Design
TOTAL BUILDING COMMISSIONING PROCEDURES
1. Purpose. This regulation provides policy and guidance for developing total building
commissioning procedures and executing/documenting commissioning activities for delivering
facilities and systems starting with the planning phase and continuing through the post
occupancy phase. The objective is to integrate total building commissioning activities into the
entire construction delivery process to ensure that systems operate to meet the owner’s project
requirements and requirements as defined in the construction contract plans and specifications.
The previous version of ER 1110-345-723 provided policy and guidance for developing systems
commissioning procedures. The primary focus of ER 1110-345-723 was limited to
commissioning of facility HVAC Controls. Current Industry, DOD, and USACE standards and
guidance have significantly expanded the commissioning scope required for USACE projects.
2. Applicability. UFC 1-200-02 references ASHRAE 189.1, section “Building Project
Commissioning”, as the commissioning requirement for new construction, new additions and
renovations. It is important to note, that for renovations, only the systems that are replaced must
be commissioned; however, commissioning efforts should include verification of how new
systems integrate with existing systems. Total Building Commissioning includes commissioning
of a variety of building systems, not just HVAC systems, and establishes the required level of
effort for commissioning on projects. This regulation applies to the following:
a. All Military Construction Army (MCA) projects executed by USACE that are subject to
any of the referenced documents regardless of location (CONUS/ OCONUS) that include over
5,000 gross square feet (GSF) of interior space and the construction cost is greater than $3
million.
b. For overseas construction activities on permanent basing and overseas construction
activities in support of contingency operations, this policy will apply to the greatest extent
practical considering mission objectives and Host Nation agreements.
c. For projects in support of others (.i.e., other military services and DOD and federal
agencies, vertical construction for USACE civil works projects), where USACE is the design
and/or construction agent, this regulation applies to the extent Total Building Commissioning has
been included in the programming documentation/funding.
This Engineering Regulation (ER) supersedes ER 1110-345-723, Systems Commissioning
Procedures, dated 31 July 1995.
