A curtain wall system has a 20-week fabrication lead time after shop drawing approval. What should the constructor do first to protect the schedule?

Answer: Prioritize and expedite the shop drawing submittal and review cycle

Long-lead items depend on approved submittals, so speeding up the submittal and review cycle protects the delivery date.

Resource leveling within available float typically results in which outcome?

Answer: Peaks and valleys in resource demand are smoothed without extending the project

Leveling moves non-critical activities within their float to smooth resource use while keeping the completion date.

A takeoff shows 10,000 SF of drywall, and the estimator uses a 10% waste factor. How much drywall should be ordered?

Answer: 11,000 SF

10,000 SF × 1.10 = 11,000 SF to cover cutting and breakage waste.

Which document lets a supplier show how a specific product meets the specification before installation?

Answer: Product data submittal

Product data submittals give manufacturer information so the design team can confirm the product complies with the specifications.

Just-in-time (JIT) delivery is most helpful on which kind of project?

Answer: A congested urban site with little storage space

JIT cuts the need for on-site storage, which matters most on tight urban sites.

A resource histogram is used primarily to:

Answer: Display resource demand over time

A histogram plots how many units of a resource (such as workers) are needed in each time period.

Which cost is classified as an ownership cost rather than an operating cost for construction equipment?
