Schedule Coordination & OPR Flashcards

How does accelerated construction scheduling typically impact the commissioning process?

Answer: It compresses testing windows, increasing risk of incomplete commissioning and unresolved issues

Accelerated schedules reduce time available for testing, increasing pressure to skip steps and raising the risk of unresolved deficiencies at occupancy.

The OPR requires the building to maintain 72°F ± 2°F in all occupied spaces. Which commissioning test best verifies this requirement under part-load conditions?

Answer: Seasonal and part-load functional performance testing across multiple control modes

Part-load conditions require testing across multiple seasons and operating modes to confirm the system maintains temperature within OPR tolerances.

What is the primary purpose of the commissioning schedule look-ahead report issued by the CxA?

Answer: To notify all stakeholders of upcoming commissioning activities so resources can be arranged in advance

Look-ahead reports give the project team advance notice of upcoming testing activities so contractors can have equipment ready and personnel available.

An OPR states that the owner requires witnessing of all functional performance tests. How should the commissioning schedule accommodate this requirement?

Answer: Schedule all functional tests with adequate advance notice to the owner and include owner witness time in test durations

OPR requirements for owner witnessing must be reflected in the schedule with sufficient advance notice and time allocated for owner participation.

Which condition would most likely require a revision to the commissioning schedule that was developed during the design phase?

Answer: A major equipment substitution that changes control sequences and requires additional testing procedures

Equipment substitutions that alter control sequences require new test procedures and additional time, necessitating a commissioning schedule revision.

How should the OPR address post-occupancy commissioning requirements to influence the commissioning schedule?

Answer: OPR should specify any seasonal testing, performance monitoring, or re-commissioning intervals needed after occupancy

The OPR should capture post-occupancy performance expectations that require ongoing or deferred testing beyond the initial commissioning period.

During a commissioning schedule review, the CxA notes that controls contractor scope includes sequence of operations programming but no time is allocated for controls checkout before functional testing. What is the risk?

Answer: Functional performance tests will fail due to unverified programming, causing retesting delays

Without controls checkout confirming sequences are correctly programmed, functional tests will likely fail, wasting time and requiring additional test sessions.
