Quiz 7 - Estimates, Construction Contract Administration & Machine Power Complete Questions &
Answers Liberty University 2026, with the strongest emphasis placed on Perform accurate quantity
takeoffs and apply appropriate pricing methods for construction estimates, Analyze contract
administration issues including change orders, delay claims, and payment provisions under
standard contract forms, Calculate machine power, productivity and and equipment cost rates to
support construction planning and estimating decisions. Every item follows the wording style and
level of reasoning you meet in the real paper, and each one is paired with a clear rationale so the
correct choice is never a guess. Work through the set at your own pace, mark the questions that
slow you down, then come back to them until the reasoning feels automatic. Learners who revise
this way walk into the exam room recognising the pattern behind the questions instead of meeting
them for the first time. Keep going - steady, honest practice is what turns a difficult paper into a
comfortable pass.
Q1 PERFORM ACCURATE QUANTITY TAKEOFFS AND APPLY APPROPRIATE PRICING
METHODS FOR CONSTRUCTION ESTIMATES
A contractor's bid includes a 5% contingency on direct cost. During construction,
an unforeseen geotechnical condition requires a $200,000 fix. The owner argues
the contingency should absorb it. Which principle best determines whether the
contractor can recover the cost as a change?
A. The contingency is a bid component owned by the contractor and does not affect entitlement;
entitlement depends on the contract's differing-site-conditions clause and whether the condition
was reasonably foreseeable. CORRECT
B. Because the contingency was included in the contract price, the owner automatically bears
the cost as a shared risk.
C. The contractor must use the contingency first; only costs exceeding 5% of direct cost are
recoverable as a change.
D. Contingency is a guaranteed maximum price mechanism, so the owner must approve any
use before work proceeds.
RATIONALE: Contingency is a pricing allowance within the contractor's bid and does not by itself
establish entitlement or allocate risk. Recovery depends on the contract's differing-site-conditions
(DSC) clause and foreseeability analysis. Options B-D misstate contingency's role and ignore the
contract's risk-allocation provisions.

,Q2 PERFORM ACCURATE QUANTITY TAKEOFFS AND APPLY APPROPRIATE PRICING
METHODS FOR CONSTRUCTION ESTIMATES
Using the data below, determine the adjusted unit price for a line item after a
quantity overrun under a typical unit-price contract with a 15% variation threshold
and a 10% price adjustment for overrun quantities.
A. $325,000
B. $318,250 CORRECT
C. $312,500
D. $300,000
RATIONALE: Threshold quantity = 10,000 × 1.15 = 11,500 CY at full price: 11,500 × $25 =
$287,500. Overrun = 13,000 11,500 = 1,500 CY at reduced price: 1,500 × $22.50 = $33,750.
Total = $287,500 + $33,750 = $321,250. Option B reflects correct calculation; others misapply the
threshold or adjustment.
Q3 PERFORM ACCURATE QUANTITY TAKEOFFS AND APPLY APPROPRIATE PRICING
METHODS FOR CONSTRUCTION ESTIMATES
A project is delayed 30 days due to owner-directed design changes. The
contractor also experienced a 10-day delay from its own subcontractor. Under a
standard AIA A201 time-extension clause, which statement is most accurate
regarding the contractor's entitlement to a time extension and associated costs?
A. The contractor is entitled to a 30-day time extension and associated costs for the
owner-directed changes, but the concurrent 10-day subcontractor delay may reduce
compensable time if it impacted the critical path. CORRECT
B. The contractor is entitled to a 40-day time extension and costs for both delays because all
delays are excusable.
C. The contractor receives no time extension because the subcontractor delay is concurrent and
non-excusable.
D. The contractor is entitled to a 30-day time extension but no costs, because design changes
are excusable but not compensable.
RATIONALE: Owner-directed changes generally entitle the contractor to both time and cost if
they impact the critical path. Concurrent subcontractor delay may be non-excusable and can
reduce compensable time if it independently affected completion. Options B-D misstate
entitlement and concurrency principles.

, Q4 PERFORM ACCURATE QUANTITY TAKEOFFS AND APPLY APPROPRIATE PRICING
METHODS FOR CONSTRUCTION ESTIMATES
Which machine-power calculation correctly determines the effective force required
to overcome grade resistance for a track-type tractor moving up a 6% slope with a
gross weight of 50,000 lb?
A. Grade resistance = 50,000 lb × 0.06 = 3,000 lb CORRECT
B. Grade resistance = 50,000 lb × sin(6°) 5,227 lb
C. Grade resistance = 50,000 lb × 0.06 × 0.5 = 1,500 lb
D. Grade resistance = 50,000 lb / 0.06 833,333 lb
RATIONALE: For small slopes, grade resistance is approximated as gross weight × grade
(decimal). Thus 50,000 × 0.06 = 3,000 lb. Option B uses sine of degrees (incorrect for percent
grade), C adds an arbitrary factor, and D inverts the relationship.
Q5 PERFORM ACCURATE QUANTITY TAKEOFFS AND APPLY APPROPRIATE PRICING
METHODS FOR CONSTRUCTION ESTIMATES
In a cost-loaded CPM schedule used for progress payment, which situation most
likely triggers a withholding of payment under standard contract provisions?
A. The contractor's schedule shows float erosion on a non-critical path.
B. The contractor failed to submit a required submittal that is a prerequisite for the scheduled
work. CORRECT
C. The contractor's actual progress is slightly ahead of the cost-loaded baseline.
D. The contractor used a different crew mix than planned but maintained productivity.
RATIONALE: Standard payment provisions allow withholding when a prerequisite submittal is
missing, as it may indicate non-compliance or risk. Float erosion, ahead-of-schedule progress,
and crew mix changes do not typically justify withholding if work complies. Options A, C, and D
are generally not valid grounds for withholding.
