Project Management & Public Works Planning Flashcards

A municipality adopts an asset management program for its public works infrastructure. The primary objective of lifecycle cost analysis within this program is to:

Answer: Optimize the total cost of ownership including construction, maintenance, and disposal over the asset's life

Lifecycle cost analysis evaluates all costs from initial construction through operation, maintenance, rehabilitation, and disposal to identify the lowest total cost of ownership strategy.

During construction of a city hall renovation, the contractor submits a request for equitable adjustment (REA) claiming unforeseen subsurface conditions. For the claim to be valid under a standard Differing Site Conditions (DSC) clause, the contractor must demonstrate:

Answer: The conditions differed materially from those indicated in the contract documents

Under a DSC clause, the contractor must show the actual subsurface conditions materially differed from what the contract documents indicated or what a reasonable contractor would have expected.

Which scheduling technique is specifically designed to manage resource conflicts by adjusting activity start dates within available float?

Answer: Resource leveling

Resource leveling redistributes work by delaying activities within their float to smooth resource demand and eliminate over-allocation without extending the critical path unnecessarily.

A municipality is considering issuing General Obligation (GO) bonds versus Revenue bonds to fund a new water treatment facility. The key distinction is:

Answer: GO bonds require voter approval; revenue bonds are repaid solely from facility revenues

GO bonds are backed by the municipality's taxing authority and typically require voter approval, while revenue bonds are repaid from the revenues generated by the funded facility.

An engineer's estimate for a road widening project is $8.2 million. The single bid received comes in at $11.5 million. The BEST practice for a public agency is to:

Answer: Reject the bid and re-advertise after reviewing the estimate and project scope

A single bid that significantly exceeds the engineer's estimate suggests a problem with the estimate, scope, or market conditions; re-advertising after review is standard practice.

In project management, a 'milestone' is BEST defined as:

Answer: A significant point or event in the project schedule with zero duration

Milestones mark significant project events such as design completion or permit approval; they have no duration but represent key checkpoints in the schedule.

A public works director wants to reduce design errors that reach the construction phase. Which quality control practice is MOST effective at catching interdisciplinary coordination issues?

Answer: Interdisciplinary design review (IDR) or 'clash detection' using BIM

BIM-based clash detection identifies conflicts between civil, structural, mechanical, and electrical designs in 3D before construction, dramatically reducing costly field conflicts.
