Which of the following risks CANNOT be estimated by BILCO with only a resource-loaded schedule?
Correct Answer: A
Understanding the Problem:
* The question asks which risk cannot be estimated using only a resource-loaded schedule.
* A resource-loaded schedule contains detailed information about activities, resources (labor, materials, equipment), and their associated costs but does not provide external information unrelated to project resources.
Analysis of Each Option:
* A. Delay due to SDOT's other projects:
* This risk depends on external factors beyond the control or visibility of the resource-loaded schedule, such as project interactions, priorities, or resource allocation managed by SDOT (the State Department of Transportation).
* A resource-loaded schedule cannot estimate this delay, as it does not account for external dependencies or priorities outside the project's scope.
* This is the correct answer.
* B. Delay due to labor shortage:
* A resource-loaded schedule tracks labor availability and allocation. By analyzing resource constraints, it can estimate potential delays due to labor shortages.
* This risk can be estimated using the schedule.
* C. Liquidated damages on the SDOT contract:
* Liquidated damages are linked to project delays. A resource-loaded schedule can estimate the delay impact and calculate potential damages based on contract terms.
* This risk can be estimated.
* D. Cost overruns due to cement shortage:
* Cement shortages directly affect the material resource allocations in the schedule. A resource- loaded schedule can estimate cost overruns by analyzing material usage and constraints.
* This risk can be estimated.
Final Answer and Justification:
* Option A is correct because a resource-loaded schedule cannot consider or predict delays caused by external projects managed by other entities like SDOT.
* All other risks relate to project resources or scheduling, which can be analyzed using a resource-loaded schedule.
Study Guide Reference:
* Refer to the PSP Certification Study Guide, Chapter 2 - Scheduling, sections on Schedule Maintenance and Risk Analysis (p. 209), and Resource-Constrained Scheduling (p. 163).
* AACE Recommended Practice 57R-09: "Integrated Cost and Schedule Risk Analysis" provides additional insights into risks measurable through schedules.
