On a petrochemical project, the owner provides a geotechnical report showing stable soil conditions. During excavation, the contractor encounters contaminated groundwater not identified in any project documents. Work stops for 14 days while remediation is arranged by the owner. This delay is BEST classified as:
Correct answer: B - Excusable, compensable delay under applicable rules
The intersection of the Work Breakdown Structure (WBS) and the Organizational Breakdown Structure (OBS) defines which of the following?
Correct answer: C - Control account for this purpose
A project network has four paths: • Path A: 4 → 6 → 3 → 5 = 18 days • Path B: 4 → 7 → 8 → 2 = 21 days • Path C: 4 → 5 → 5 → 4 = 18 days • Path D: 4 → 9 → 6 → 3 = 22 days Activity X lies on Path B only. It has an Early Start of day 4 and a duration of 7 days. Its only successor has a Late Start of day 16. What is the Total Float of Activity X?
Correct answer: C - 5 days for this purpose
A project reports the following Earned Value data at month 6: • BAC = $1,200,000 • PV = $500,000 • EV = $420,000 • AC = $480,000 The project manager believes current cost performance will continue for the remainder of the project. What is the Estimate at Completion (EAC)?
Correct answer: D - $1,371,429 under standard market practice
During a forensic schedule analysis, an analyst removes owner-caused delay events from the as-built schedule and recalculates the network to determine what the completion date would have been without those delays. Which Method Implementation Protocol from AACE RP 29R-03 is being applied?
Correct answer: D - MIP 3.8 - Collapsed As-Built in the standard framework
A DCMA 14-point schedule health assessment reveals the following results: • 88% of relationships are Finish-to-Start • 4% of activities have lags • 2% of activities have hard constraints • CPLI = 1.03 Which metric fails to meet the DCMA threshold?
Correct answer: A - Relationship Types under accepted convention
Activity R has the following three-point duration estimate: Optimistic = 10 days, Most Likely = 14 days, Pessimistic = 24 days. Using the PERT formula, what is the standard deviation of Activity R?
Correct answer: B - 2.33 days under applicable rules
A scheduler needs to resolve a resource over-allocation on a construction project. The project completion date is contractually fixed and cannot change. Which approach should the scheduler use?
Correct answer: C - Resource smoothing as commonly understood
Three activities on the critical path are candidates for crashing: • Activity E: Normal 12d/$6,000 - Crash 9d/$9,000 • Activity G: Normal 8d/$4,000 - Crash 6d/$5,400 • Activity J: Normal 15d/$10,000 - Crash 12d/$12,400 To reduce the project duration by 2 days at the lowest cost, which activity should be crashed first?
Correct answer: D - Activity G for this purpose
A project has a critical path length of 200 working days. The contract required completion date allows 190 working days. What is the Critical Path Length Index (CPLI)?
Correct answer: B - 0.95 as ordinarily interpreted
