Question 1

Which statement best describes a key limitation of using a green building or infrastructure rating system's certification level as the sole measure of a project's sustainability performance?

Correct Answer: It records strategies documented at certification, not measured operating results

A certification level reflects the design and construction strategies documented and verified at the time of certification. It does not confirm how the facility actually performs once occupied. Real energy use, water use and occupant outcomes can differ widely from design intent, so measured operating data is needed to judge true sustainability performance.
Credits are not weighted equally. Systems such as LEED assign more points to high-impact categories like energy. Infrastructure has its own third-party pathway through Envision. Certification depends on independent review by bodies such as GBCI or ISI, not on the design team's self-assessment.
Key concept: rating certification shows design intent, not verified operational performance.

Question 2

During a courthouse renovation pursuing a green building rating, the specifications require certified wood for new millwork, supported by chain-of-custody documentation. The mill's certificate is valid. However, the millwork was bought through a distributor whose invoices show no chain-of-custody number. The contractor says the mill's certificate is enough to support the credit. How should the construction manager assess the contractor's position?

Correct Answer: The claim stays unproven unless the distributor holds its own custody certificate for that sale

Certified wood claims under FSC-type systems require an unbroken chain of custody, so every entity that takes legal ownership of the product, including a distributor, must hold its own valid chain-of-custody certificate and show it on sales documents. Without that, the claim cannot be verified.
The mill's certificate does not carry through later sales; it covers only the mill's own handling and sales. An installer's written statement is not third-party certification and cannot replace a missing chain-of-custody link. The gap is not just a cost-record issue, because the missing certificate number breaks the documentation needed to earn the credit at all.
Key concept: unbroken chain-of-custody certification for certified wood.

Question 3

At a mixed-use housing development nearing turnover, the owner's facilities staff will operate the central plant and the retail-level HVAC systems. The general contractor proposes closing out its commissioning obligations by delivering the O&M binders and the as-built drawings. Under the commissioning plan, which additional deliverable should the construction manager confirm is complete before recommending that the owner accept turnover?

Correct Answer: Specified operator training for owner staff and a systems manual on intended operation

Because owner staff will run the central plant and retail HVAC, the commissioning plan requires documented operator training and a systems manual explaining design intent and intended operation. O&M binders and as-builts show what was installed, but they do not prepare staff to operate the systems.
A seasonal retest is often deferred until after occupancy, and a tenant punch walk is a general closeout task, not a commissioning turnover deliverable. Startup reports and contractor QC checklists are produced earlier, during construction-phase verification. A calibrated energy model is not a standard commissioning turnover requirement.
Key concept: commissioning closeout includes owner training and a systems manual that transfer operational knowledge, not just equipment documentation.
