7.2.11.4 Prior to a meeting (usually a minimum of three days) an agenda should be distributed to all invited attendees. The agenda should include the following:
a. Meeting location b. Start time c. List of invited attendees d. List of items to cover (previous action items, outstanding
issues, schedule review, new issues, and other business) along with defined time allotments for each item e. End time f. Attachments, if applicable
7.2.11.5 The meeting time and duration should be strictly adhered to. This will set the tone for other Cx Activities.
7.2.11.6 Within a reasonable and established period (frequently, three days) after the meeting, distribute meeting notes or minutes. This should include the following:
a. Date, time, and location of the meeting b. List of attendees c. Resolved action items and issues d. Outstanding action items and issues, including clear iden tification of the responsible party and due dates e. Date, time, and location of the next meeting
7.2.12 Accomplish Periodic Site Visits to Verify Compli- ance with the OPR
7.2.12.1 Site visits are the primary method used during the Construction Phase to verify that the installed systems and assemblies comply with the OPR.
7.2.12.2 A clear, concise, and consistent procedure must be followed for each site visit to properly identify Construction Phase process problems and issues.
7.2.12.3 The site visit procedure uses statistical sampling techniques for verification of the construction checklists and record documents. This provides assurance that the verification process is not biased and has reliable consistency. The recommended procedure has the following general steps:
a. Identify the current state of construction to define the
scope of systems and assemblies that can be verified. The construction checklists completed since the previous site visit provide one way to define this scope. b. Randomly select between 2% and 10% of the systems and
assemblies identified for verification. This can be accomplished by randomly selecting a starting point and selecting every tenth item from a list or by automatically generating a random sample from a computerized database. c. Identify CxP Team members for the site visit. d. Review the OPR. e. Accomplish verification. This task is completed by going
to the selected system or assembly and comparing the installation to the completed (full or partial) construction checklists. Any negative responses should be reviewed in detail. f. Any consistent problems with the installation identified (typically more than 10% of the sample has the same issue), including record documents, are documented in general terms and provided to the contractor for resolu
tion. The contractor is then responsible for 100% checking of all affected systems or assemblies and making corrections as required. g. Any inconsistent problems (one or two occurrences) are
sent to the contractor, detailing the specific component, system, or assembly for resolution. h. Meet with contractors to discuss any issues identified and
the general progress of the project. i. Meet with the Owner’s representative to review the findings, project schedule, and outstanding issues. j. Develop a site visit report and distribute to the CxP Team members and other interested parties. k. Update the issues and resolution log.
7.2.13 Test Execution 7.2.13.1 During test execution there can be witnessing of tests, verification of tests, or verification of test data reports. Typically, only one of these is performed by the CxP for a specific test or series of tests. However, depending on the type and complexity of the test, it is possible in some cases to witness a portion of the test, verify the test through a random sampling of components, and verify the test data report through random sampling of the reported results.
7.2.13.2 Completion of tests should comply with the following:
a. Tests shall be performed according to approved written
procedures. Results of test performance shall be recorded on the test data forms and witnessed. b. Deviations from the approved procedures, if permitted,
should be documented in writing. c. Test data should be recorded under steady-state and stable
conditions. d. If an issue is observed during a test, the test should be ter minated within the scope of the contract. An issue report is created at the time of observation. If the issue cannot be resolved within a reasonable time period, it may be required to run the test immediately, with the understood options to run the test later after all issues are resolved. e. If an issue is discovered during review of the data, the
issues shall be resolved or the test repeated in its entirety. f. Upon completion of the test, the technician performing the test and the witnesses sign the test data record, attesting to the verity of the recorded observations.
7.2.13.3 Generally, the sequence of testing will be executed in the order of activities listed:
a. The verification of the construction checklists begins with
equipment or assembly delivery and continues through start-up and testing. b. Tests verifying system and intersystem performance
according to the OPR cannot begin until the construction checklists have been verified and accepted by the CxP Team. c. Other sequencing requirements, depending on the specific
system, may be required to ensure the proper conditions are present or can be created. d. A specified test is run according to contract documents or
to manufacturer requirements.
