Definitions
Basis of Design (BOD): The documentation by the design team of the primary
thought processes and assumptions behind design decisions that are made to
meet the Owner's Project Requirements. The BOD describes the assumptions
used for sizing and selection of systems (i.e. codes, standards, operating condi-
tions, design conditions, weather data, interior environmental criteria, other
pertinent design assumptions, etc.).
Commissioning (Cx): The National Conference on Building Commissioning has
established an official definition of `Total Building Commissioning' as follows:
"Systematic process of assuring by verification and documentation, from
the design stage to a minimum of one year after construction, that all facil-
ity systems perform interactively in accordance with the design documen-
tation and intent, and in accordance with the owner's operational needs,
including preparation of operation personnel"
Commissioning Agent (CxA): The qualified person, company or agency that
plans, coordinates and oversees the entire commissioning process.
Commissioning Plan: The document prepared for each project that describes
all aspects of the commissioning process including schedules, responsibilities,
documentation requirements and communication structures.
Commissioning Record: The complete set of commissioning documentation for
the project which is turned over to GSA at the end of the construction phase.
Construction Checklist: A checklist to ensure that the specified equipment
has been provided, is properly installed and initially started and checked out
adequately in preparation for full operation and functional testing.
Functional Tests: Tests that evaluate the dynamic function and operation of
equipment and systems using direct observation or other monitoring methods.
Functional testing is the assessment of the system's (rather than just compo-
nent's) ability to perform within the parameters set up within the Owner's
