Commissioning Scope

Commissioning (Cx) is a systematic process of observing and documenting that a building’s

systems installation, calibration, and performance meets both the Owner’s Project

Requirements (OPR) and the design team’s Basis of Design (BOD). For this project the

schematic design documents and narratives will serve as the OPR and BOD. In order to

achieve the maximum benefit from the Cx process, it is recommended that Cx begin during

the design phase of the project to provide quality control of documentation for the systems

to be commissioned and continue through construction, acceptance, and post-occupancy. In

accordance with Guiding Principles for Federal Leadership in High Performance and

Sustainable Buildings, the commissioning process is intended to achieve specific goals in

each phase of the project.

DESIGN PHASE: Commissioning during design is intended to achieve the following

objectives:

• Review 100% design development documents prior to start of construction documents

phase.

• Review construction documents, including OPR and MEP BOD, at 100% submittals.

• Incorporate the Cx requirements into the project by issuing the Cx specifications.

4● Page

• Develop the Commissioning Plan (Cx Plan).

CONSTRUCTION PHASE: Commissioning during the construction of this project is intended

to achieve the following specific objectives:

• Review submittals of commissioned systems.

• Observe and document that equipment and systems are installed properly and receive

adequate operational inspection by installing contractors.

• Observe and document performance of equipment and systems through normal and

emergency operational modes necessary to meet design intent.

• Provide the owner with a final Commissioning Report that documents the commissioning

process and results.

The construction phase begins at the end of the design phase, during this phase the

commissioning process includes the tasks below1:

• Review Submittals of Commissioned Systems: The CxA reviews submittal data related to

the systems being commissioned, and provides comments to the design team and

construction manager. The CxA works with the design team and construction manager

to address any issues or concerns identified during the review. The comments,

responses, and resolutions are documented in the submittal review log.

• Update the Cx Plan: The CxA updates the Cx Plan periodically throughout the design and

construction of the project as needed.

• Commissioning Kick-off Meeting: The kick-off meeting occurs after contracts have been

awarded prior to equipment installation. The meeting includes the CxA, design team, the

contractor, and subcontractors, (including the mechanical, electrical and plumbing

contractors); the owner is also encouraged to attend.

• Commissioning Schedule: The schedule is discussed at the Cx Kick-off meeting and

dates for key commissioning activities are placed on the overall construction schedule.

• Review of Submittals: Submittals of the equipment to be commissioned are reviewed for

compliance with the construction documents, OPR, BOD, and the ability to be

commissioned. Comments are provided to the CM. Issues, if found, are documented on

the Master Issues Log.

• Pre-functional Checklists: The CxA will create and complete pre-functional checklists for

equipment to be commissioned on the project. These checklists are used to verify the

equipment arrived on site, is the correct equipment and is installed per design and per

manufacturer’s recommendations.

• Site Visits: Site visits are conducted by the CxA periodically throughout construction.

The goal of the site visit is to observe the installation of the equipment to be

commissioned and observe that the equipment and systems meet the criteria of the OPR

and BOD. The CxA will document observations and issues identified in a Site Visit

Report.

checklists provided by the CxA are not a substitute for manufacturer’s checklists and

startup procedures. The manufacturer checklists and startup procedures are provided

the CxA and are included in the Cx Report.

• Create Functional Performance Tests: The CxA creates the functional performance tests

based on submittal information and intended system operation. The systems are tested

to perform as intended in normal and emergency modes of operation.

Acceptance Phase

The acceptance phase will begin toward the end of construction, when the systems are

ready for testing, during this phase the commissioning process will provide the following2:

• System Testing Readiness: The installing contractor will be responsible for certifying that

the commissioned systems are ready for functional performance testing. The Engineer of

Record’s punch list items will need to be accepted by the Engineer of Record. The

Engineer of Record will notify the CxA when their punch list has been accepted. The

contractor will provide the completed prefunctional checklists, start-up reports, controls

testing reports, and TAB report to the CxA for review prior to the CxA scheduling

execution of the functional performance tests.

• Functional Performance Testing: Functional performance testing is conducted by the

contractors, and witnessed and directed by the CxA. The testing includes the systems

and equipment that are included in the commissioning process. The systems and

equipment are tested to demonstrate compliance with the OPR, BOD, and construction

documents. The systems are tested in normal operating mode as well as emergency

operating mode, if applicable.

• Master Issues Log (MIL): At the end of the acceptance phase, the issues in the MIL will

be either resolved, or a clear path to resolution has been identified and documented in

the MIL.

• System Acceptance: After completion of the functional testing and MIL as noted above,

the CxA will recommend acceptance of the commissioned systems to the Owner,

Architect, and Engineer of Record.

• System Training: After the systems have been accepted by the Owner, the contractor

will schedule system training with the Owner. The training should be conducted by the

installing contractor and/or manufacturer’s representative. The training should be

provided to the building’s operations and maintenance (O&M) staff. For each training

session, the contractor and/or manufacturer’s representative will provide an agenda to

the CxA for review prior to the meeting. Also, for each training session, the contractor

and/or manufacturer’s representative will be responsible for documenting training

attendance. Attendance sheets will be submitted to the CxA.

Introduction

The Owner’s Project Requirements (OPR) document is used to articulate the most important

goals and objectives of the project from the point of view of the owner. The OPR is a detailed

collection of the functional requirements of a project and the expectation of the building’s use

and operation. This document is intended for use by the owner, design team, construction

team, operation and maintenance staff, future renovation teams, and anyone who needs

access to the original project information. The OPR forms the basis from which design,

construction, operation and acceptance decisions are made. Each item of the OPR may have

defined performance and acceptance criteria. Those that can be benchmarked should have the

benchmark defined in specific terms and measurement.

During the course of design and construction, the OPR is updated to reflect changes to the

original project goals. Updates to the OPR during the design and construction process are

primarily the responsibility of the owner.

This OPR is a precursor and companion to the Basis of Design (BOD) document that provides

detailed information on how the owner’s requirements are to be met through the development

of the design documents, and/or implementation during construction, and/or operation. The

BOD is developed by the design team to reflect the requirements as specified in this OPR.

To meet BLM requirements, the owner’s intent is for the completed Fire Station to be

compliant with the five Federal Guiding Principles for High Performance and Sustainable

Buildings. Requirements and strategies outlined in this document are driven by that goal.

Overview of Project

The Bureau of Land Management (BLM) has a strong commitment to high quality building

construction, including sustainable design. In 2006, the BLM furthered their commitment to

sustainability by pursuing compliance with the Federal Guiding Principles for High Performance

and Sustainable Buildings (GP’s or Guiding Principles) on all new building projects.

The project referenced in this document will be the new Fire Station for the Weaver Mountain

BLM site. It will be a statement of commitment to the environment and a showcase for the

community and the public that BLM serves.

The building designers should pursue sustainable objectives both within and outside the

Guiding Principles whenever possible. BLM’s commitment to sustainability is consistent with

the desire to have integrated design and construction that exceeds industry standards both

functionally and aesthetically.

The following items are described in this OPR:

• Owner Requirements

• Environmental and Sustainability Goals

• Energy Efficiency Goals

• Indoor Environmental Quality Requirements

• Equipment and System Expectations

• Building Occupant and O&M Expectations
