This review looks for completeness of the drawings and for items of concern identified during previous reviews.
6.2.8.4 Sample areas of the facility, 10% to 20% of the total area, are reviewed in detail to evaluate the coordination accomplished within and among disciplines. This includes reviewing for constructibility and interfaces among disciplines. The intent of this review is to determine whether there are systematic errors, not to fully check the drawings. The responsibility for completely checking the drawings for coordination and accuracy remains with the Design Team.
6.2.8.5 A discipline-specific review involves a review of the construction documents along with the BoD, design calculation assumptions, and methods for compliance with the OPR. A sampling strategy of focusing on 10% to 20% of the drawings provides for an in-depth analysis and evaluation of the ability of the documents to meet the OPR.
6.2.8.6 A review of the specifications is performed to determine completeness and applicability to the project. A review of 10% to 20% of the specification is performed in detail for verification of compliance with the OPR. Items checked include applicability of the section to the project, Cx requirements, submittal requirements, applicability of equipment, training requirements, and coordination with other sections.
6.2.8.7 See Informative Appendix N for additional guidance on how to accomplish quality-based design reviews.
6.3 Design Phase Acceptance Requirements
6.3.1 The Cx should include the formal acceptance by the Owner of the BoD and the updated OPR during the Design Phase, following review and comment by the CxP.
6.4 Design Phase Documentation Requirements
6.4.1 Construction document commissioning requirements, updated OPR, updated Cx Plan, the updated issues and resolution log, and the Cx Progress Reports are the primary documentation requirements for the Design Phase Cx.
6.4.2 The information in these deliverables is used throughout subsequent project phases, including occupancy and operations.
6.5 Design Phase Training Identification Requirements
6.5.1 Training requirements for facility, system, and assembly O&M are addressed during the Design Phase by the completion of a training requirements identification workshop, development of the Construction Phase and Occupancy and Operations Phase training program, and inclusion of the training program requirements in the Cx Plan and construction documents.
7. CONSTRUCTION PHASE
7.1 Introduction 7.1.1 During the Construction Phase of the project delivery process, systems and assemblies are installed, inspected, tested, and placed into service to meet the OPR. This phase may also include bidding, negotiation, and contracting activities. The Systems Manual is delivered during this phase and training is provided.
7.1.2 Construction Phase Cx objectives include the following:
a. Updating the OPR b. Updating the Cx Plan c. Verifying that submittals meet the OPR d. Developing detailed test procedures and data forms e. Verifying that systems and assemblies comply with the
OPR f. Delivering the Systems Manual g. Verifying training of the Owner’s O&M personnel and
occupants. h. Acceptance of Construction Phase Cx Activities
7.1.3 Construction Phase Cx Activities described in this section that are to be performed by the Design Team and special consultants must be included in the scope of services described in the Owner/Design Professional Service Agreement. These Cx Activities may be more than are normally required in their scope of services. The scope of services in the Owner/Design Professional Service Agreement should also include the requirement to cooperate with the CxP during the Predesign Phase, Design Phase, and Construction Phase of the project. This may include material TAB; performance tests; records; photography; outside training; Owner’s furnished equipment vendors; and other requirements during the Construction Phase.
7.1.4 If the Cx on a particular project begins at the Construction Phase, Cx Activities described for the Predesign Phase and Design Phase must be completed before the following Construction Phase activities begin.
7.2 Construction Phase Cx Activities 7.2.1 Construction Phase Cx Responsibilities 7.2.1.1 During the Construction Phase, the CxP Team works to verify that systems and assemblies are installed in a manner that will achieve the OPR.
7.2.1.2 Use quality-based sampling for verification of each task and test determined to be related to the OPR during the Construction Phase. See Informative Appendix N for additional guidance.
7.2.1.3 Conduct and document regularly scheduled CxP Team meetings to facilitate coordination and cooperation in delivering a facility that meets the OPR.
7.2.1.4 Essential team members during the Construction Phase include Owner’s representatives, the CxP, design professionals, contractors, suppliers/vendors, and construction/ program/project managers.
7.2.1.5 Responsibilities of the CxP Team during the Construction Phase include the following:
a. Participate in the prebid conference. b. Coordinate participation of Owner’s representatives. c. Identify specialists who will be responsible for accomplish ing the Cx Activities for specific systems and assemblies. d. Update the OPR to reflect decisions made during bidding
and construction. e. Update the Cx Plan. f. Conduct a preconstruction Cx meeting.
