2026/2027 | COMPLETE QUESTIONS AND ANSWERS (VERIFIED
ANSWERS) | EXAM PREP | COMPREHENSIVE EXAM GUIDE
2026&2027
1. A South Carolina contractor has passed the NASCLA Accredited Examination for
Commercial General Building Contractors. Which statement best describes what
that examination provides?
A. An automatic South Carolina contractor license
B. A waiver of every South Carolina licensing requirement
C. A standardized examination credential that may satisfy the trade-examination
requirement in participating jurisdictions
D. Automatic authority to perform electrical, plumbing, and HVAC work
Answer: C
The NASCLA examination is not itself a license. It can satisfy the trade-examination
requirement in participating jurisdictions, but the contractor must still meet applicable state
licensing requirements.
2. A contractor wants to use a NASCLA examination result when applying in South
Carolina. What is the most appropriate next step after passing the NASCLA
examination?
A. Apply to the appropriate South Carolina licensing authority and satisfy its remaining
requirements
B. Begin work immediately without further licensing action
C. Submit the NASCLA certificate only to the local building department
D. Obtain a second NASCLA examination before applying
Answer: A
Passing NASCLA does not automatically issue a South Carolina license. The applicant must still
complete the applicable state licensing process.
3. A project manager discovers that a subcontractor has begun work outside the
classification for which the subcontractor is properly licensed. What should the
general contractor do first?
A. Ignore the issue if the work appears technically sound
B. Stop the unauthorized scope and verify the subcontractor's licensing authority
C. Allow the work to continue until the next inspection
D. Transfer the entire project to the subcontractor
Answer: B
,A contractor should not knowingly permit work outside the subcontractor's authorized scope.
Verifying licensing and correcting the situation protects the owner and the project from
regulatory and contractual exposure.
4. A contractor is preparing a bid and discovers that the plans contain a dimensional
conflict between the architectural drawings and structural drawings. What is the
best course of action?
A. Use whichever dimension produces the lowest bid
B. Average the two dimensions
C. Wait until construction begins
D. Request clarification through the appropriate project communication process before
pricing the affected work
Answer: D
Resolving discrepancies before bidding reduces change orders, disputes, and estimating
errors. The contractor should obtain an authoritative clarification rather than making an
unsupported assumption.
5. Which document generally establishes the contractual scope of work, price, and
other agreed obligations between the owner and contractor?
A. Construction contract
B. Daily weather report
C. Equipment inspection tag
D. Material delivery ticket
Answer: A
The construction contract is the primary agreement defining the parties' obligations, scope,
compensation, and other contractual terms.
6. A contractor receives a written change directive that adds substantial work to the
original scope. What is the most important immediate consideration?
A. Whether the crew can work overtime
B. Whether the additional work should be performed without documentation
C. Whether the change is properly authorized and how its cost and schedule impacts will
be documented
D. Whether the contractor can invoice the owner before performing any work
Answer: C
A properly documented change establishes authorization and provides a basis for
determining adjustments to contract price and schedule.
7. Which estimating practice provides the strongest protection against overlooking a
significant project cost?
, A. Estimating from memory
B. Using a detailed quantity takeoff and cost breakdown
C. Basing the estimate solely on the previous project
D. Allowing the field crew to determine the final price
Answer: B
A detailed quantity takeoff and cost breakdown systematically identifies labor, materials,
equipment, subcontractor, and other project costs.
8. A contractor's direct construction costs are $180,000 and the company applies a
15% markup to those costs. What is the resulting price before any additional
adjustments?
A. $189,000
B. $195,000
C. $207,000
D. $215,000
Answer: C
Fifteen percent of $180,000 is $27,000. Adding that amount to the direct cost produces a price
of $207,000.
9. Which cost is most appropriately classified as a direct cost on a specific construction
project?
A. Concrete purchased specifically for the project's foundation
B. Annual office rent
C. Company-wide accounting software
D. General corporate advertising
Answer: A
A direct cost can be specifically traced to a particular project. Materials purchased specifically
for that project's foundation are a typical example.
10. A contractor notices that actual labor hours are consistently exceeding the estimate
on a repetitive installation activity. What should management do first?
A. Immediately double the labor rate
B. Eliminate quality inspections
C. Investigate the production variance and determine its cause
D. Reduce employee wages
Answer: C
A variance should first be analyzed to determine whether the cause is estimating error,
productivity, site conditions, training, scheduling, or another factor.
, 11. Which action best demonstrates effective construction project scheduling?
A. Scheduling each trade independently without considering dependencies
B. Identifying activities, durations, relationships, and required resources
C. Scheduling only the final inspection
D. Allowing each subcontractor to establish unrelated completion dates
Answer: B
Effective scheduling coordinates activities, dependencies, durations, resources, and
milestones so that work can progress efficiently.
12. A critical activity is delayed by five working days and has no available float. What is
the most likely consequence?
A. The project completion date may be delayed by approximately five working days
unless recovery measures are taken
B. The project completion date cannot be affected
C. Only material costs will increase
D. The delay automatically becomes a contractor profit
Answer: A
A critical-path activity with no float directly threatens the scheduled completion date unless
the contractor can recover time elsewhere.
13. A subcontractor reports that a material delivery will arrive two weeks late and
affect a critical activity. What is the best project-management response?
A. Conceal the delay from the owner
B. Wait until the activity becomes critical
C. Remove the activity from the schedule
D. Assess the schedule impact and develop an appropriate recovery or resequencing plan
Answer: D
Early identification allows the contractor to resequence work, obtain alternatives, accelerate
procurement, or otherwise reduce the impact on the project schedule.
14. Which scheduling technique is particularly useful for identifying the sequence of
activities that controls the minimum project duration?
A. Straight-line depreciation
B. Critical Path Method
C. Cash-basis accounting
D. Material reconciliation
Answer: B
