Read the accompanying practice directions before starting. This original paper form has 180 questions: allow 220 answering minutes plus ten-minute breaks after Questions 30 and 105 (240 elapsed). These conservative timings and boundaries are editorial adaptations; see the directions for the published timing conflict and scoring limits. Use a basic calculator and scratch paper. Choose one answer unless told to select TWO; follow the stated rules for mappings and graph marks. Retain each shared brief for its five questions.
Shared case: Community energy retrofitA community center is replacing its heating plant and improving the building envelope. The sponsor wants a 20% reduction in annual energy use. Occupants want dependable heating and uninterrupted access to the center's evening programs. The project uses a predictive plan because the installation depends on a permit and one scheduled shutdown. The sponsor authorizes changes to the outcome targets. A change board authorizes changes to the approved scope, cost and completion baseline.
The current brief lists the energy target and an installation date. It does not define how service reliability will be measured. A maintenance representative was consulted during design, but no acceptance or operating handover tasks appear in the work breakdown. The replacement plant must satisfy the safety requirements identified by the project's competent safety adviser. Demonstrating compliance is a condition of acceptance, rather than an optional enhancement.
A supplier now proposes a controller that could further reduce energy use. It would cost $18,000 more and might extend commissioning by two days. The supplier has not yet provided a verified installation or testing schedule. No change has been approved. Use these facts for Questions 1–5.
Which addition to the shared project vision would best resolve the gap between the sponsor and occupants?
- ☐ A. A labor-efficiency target and the energy target, measured at installation
- ☐ B. An energy target and a completed supplier commissioning certificate
- ☐ C. An agreed energy target together with a measurable heating-reliability outcome
- ☐ D. The energy target and a dated installation milestone with monthly sponsor reports
Show answer and explanation
Response: C
Final answer: An agreed energy target together with a measurable heating-reliability outcome.
A commissioning certificate can demonstrate supplier checks, which makes B useful delivery evidence, but it leaves the occupants' operating concern undefined. D has the same gap. Its milestone and reporting arrangements say when and how delivery is tracked. Construction labor in A is another delivery measure. Adding a measurable heating-reliability outcome alongside the agreed energy target, as C does, lets the shared vision address both groups' stated needs after the retrofit enters use.
