Figure 2: Sequence of commissioning tasks on design/build projects.

Ideally, the Cx process should be tailored to suit design/build, so that it is more effective and less costly to provide than the unmodified Guideline 0-2005 process.

Commissioning Design/Bid/Build Projects

Figure 1 shows a simplified time line to illustrate the phases of a design/bid/build project, and the series of tasks that make up the commissioning process. With the design completed prior to the construction phase, the project design and construction tasks as well as the commissioning tasks are sequential with little overlap. Because of this, a simple linear flow chart can be used to represent the commissioning process and its sub-tasks. This particular example shows the LEED-required approach to design review. The back-check of the design documents is listed here as “Design Review 2.”

Commissioning Design/Build Projects

between design and construction, the project phases as well as the commissioning tasks are reordered and overlap. Therefore, a series of tasks in a single line sequence, as used for the design/bid/build process, no longer suffices. The commissioning tasks in Figure 2 are presented in Gantt chart format to clarify the extended time frames and the overlapping of commissioning tasks. “Pre-spec” in this figure is an abbreviated reference to the documents used by the owner to solicit design/build proposals, sometimes called bridging documents. The commissioning process should reflect the realities of design/build in plans and schedules, and also requires nontrivial changes in the commissioning process. For example, the approach to commissioning design review may require substantial revision for design/build projects. Instead of allencompassing reviews of complete sets of project documents, partial document packages may require phased review over an extended period of time to support a design/build project’s progress.
