Project Planning Flashcards
(20 cards)
What is the primary goal of a quantity take-off in project planning?
To determine the quantities of materials, labor, and equipment needed for a project.
Name two common tools used for digital quantity take-off.
Bluebeam Revu and PlanSwift.
What unit would you typically use to measure concrete for a foundation slab?
Cubic yards or cubic meters.
How do you calculate the quantity of rebar in a concrete slab?
By multiplying the slab area by the rebar spacing and then determining the number and length of bars needed.
What are the three common types of cost estimates?
Preliminary, detailed, and engineer’s estimates.
What is a contingency in cost estimating?
A reserve amount added to cover unforeseen costs or risks.
What is the typical range of accuracy for a preliminary estimate?
±20% to ±50%.
What method is used to estimate costs by comparing similar past projects?
Analogous estimating.
What is a Gantt chart used for?
To visually display the schedule of project activities over time.
What does the critical path represent in a project schedule?
The longest path of dependent activities determining the minimum project duration.
What scheduling method uses forward and backward passes to determine activity float?
Critical Path Method (CPM).
What is “float†in project scheduling?
The amount of time an activity can be delayed without delaying the overall project.
What is the purpose of a Work Breakdown Structure (WBS)?
To break down a project into manageable tasks and activities.
What is a predecessor activity?
An activity that must be completed before a subsequent activity can begin.
What is a dependency in project scheduling?
A logical relationship between two tasks where one task depends on the start or finish of another.
What is the difference between finish-to-start and start-to-start relationships?
Finish-to-start requires the first task to finish before the second starts; start-to-start allows both tasks to start at the same time or with a lag.
What is the present worth method used for?
Comparing the current value of future cash flows from different alternatives.
What is lifecycle cost analysis?
Evaluation of the total cost of ownership over the asset’s useful life, including construction, operation, maintenance, and disposal.
How do you determine the most economical alternative using present worth?
Choose the alternative with the lowest present worth of costs (or highest for benefits).
Name one sustainability factor considered in project planning.
Energy efficiency, material recyclability, or long-term environmental impact.
