SCE Construction Management 2 — Questions and Answers
Question 1: What is the work breakdown structure (WBS) in construction management?
- A hierarchical decomposition of the total project scope into manageable work packages (Correct answer)
- A list of workers on the project
- The building's structural framework
- A construction safety checklist
Correct answer: A hierarchical decomposition of the total project scope into manageable work packages
The WBS decomposes the entire project scope into progressively smaller, manageable components (phases → deliverables → work packages → activities), forming the basis for scheduling, costing, and control.
Question 2: Quality control in construction involves:
- Systematic inspection and testing to verify work meets specifications and standards (Correct answer)
- Only final inspection at completion
- Only visual inspection
- Reducing quality to save money
Correct answer: Systematic inspection and testing to verify work meets specifications and standards
Construction QC includes incoming material testing, in-process inspection (rebar placement, concrete pour, compaction), testing (cube tests, soil density), and documentation, all per approved quality plans.
Question 3: The Gantt chart is used in construction for:
- Visually displaying the project schedule with activity bars against a time axis (Correct answer)
- Calculating structural loads
- Designing building layouts
- Measuring concrete strength
Correct answer: Visually displaying the project schedule with activity bars against a time axis
Gantt charts show activities as horizontal bars on a time axis, displaying start/finish dates, duration, dependencies, and progress. They are the most common scheduling visualization tool in construction management.
Question 4: In Saudi construction contracts, a variation order is:
- A formal instruction to change the scope, specification, or timing of contracted work (Correct answer)
- An order to stop all work
- A payment certificate
- An inspection report
Correct answer: A formal instruction to change the scope, specification, or timing of contracted work
Variation orders (change orders) formally document changes to the original contract scope, including additions, deletions, or modifications. They must be properly documented and valued per contract provisions.
Question 5: What is the purpose of a project risk register in construction?
- To identify, assess, and plan responses to potential project risks (Correct answer)
- To list completed tasks
- To track worker attendance
- To calculate profit margins
Correct answer: To identify, assess, and plan responses to potential project risks
A risk register documents identified risks, their probability and impact, risk owners, and planned mitigation/response strategies. In Saudi construction, risks include extreme heat, supply delays, and regulatory changes.
Question 6: Resource leveling in construction scheduling aims to:
- Smooth out resource demand over time by adjusting non-critical activity timing (Correct answer)
- Increase project cost
- Add more critical activities
- Reduce the number of workers permanently
Correct answer: Smooth out resource demand over time by adjusting non-critical activity timing
Resource leveling uses available float to reschedule non-critical activities, preventing resource peaks and valleys. This reduces mobilization/demobilization costs and improves efficiency.
