In a cost-loaded schedule, what does the Performance Measurement Baseline (PMB) represent?
Answer: The time-phased budget plan against which project performance is measured
The PMB is the time-phased budget baseline that integrates scope, schedule, and cost, serving as the reference for measuring earned value performance.
When a cost-loaded schedule shows a Schedule Variance (SV) of -$50,000, what does this indicate?
Answer: The project is $50,000 behind schedule in cost terms
A negative SV (EV minus PV) means the project has accomplished less work value than was planned at that point in time.
Which resource type is most commonly used as the basis for cost-loading a construction schedule?
Answer: Labor hours converted to dollars
Labor hours multiplied by loaded labor rates are the most common basis for cost-loading because labor drives the majority of direct project costs.
A project has a BAC of $1,000,000 and a CPI of 0.80. What is the Estimate at Completion (EAC) using the CPI-based formula?
Answer: $1,250,000
EAC = BAC ÷ CPI = $1,000,000 ÷ 0.80 = $1,250,000, projecting overrun if current cost efficiency continues.
In cost-loaded scheduling, 'front-loading' of costs refers to what practice?
Answer: Inflating early activity budgets to improve early cash flow
Front-loading intentionally shifts budget weight to early activities, often to improve contractor cash flow at the owner's expense.
What is the primary purpose of reconciling a cost-loaded schedule with the project's Control Account Plan (CAP)?
Answer: To verify that budgets assigned to activities roll up correctly to control accounts
Reconciliation confirms that activity-level budgets aggregate correctly to control accounts, maintaining traceability from work packages to the PMB.
On a cost-loaded schedule, what does a flat S-curve indicate about project cash flow?
Answer: Early and late spending are both low, with peak spending in the middle period
A typical S-curve is flat at the start (mobilization) and end (closeout), with the steepest slope in the middle when construction activity peaks.
