1. An electrical contractor is preparing a bid for a large commercial
project that includes a new service, feeders, branch circuits, motor
loads, emergency power, lighting controls, and communication
systems. Which estimating approach provides the most reliable basis
for determining the electrical contract price?
A. Estimate only the major equipment and assume miscellaneous
materials will be insignificant
B. Multiply the building's floor area by an average historical electrical
cost without reviewing the documents
C. Perform a detailed review of drawings and specifications, complete
quantity takeoffs, evaluate labor productivity, equipment, materials,
,subcontractors, permits, supervision, overhead, schedule requirements, and
project risks
D. Use the lowest price submitted by a material supplier as the final
contract amount
Answer: C
Rationale: A reliable electrical estimate requires a complete assessment of
the project scope, quantities, labor, materials, equipment, indirect costs,
schedule constraints, and risks rather than relying on a simplified historical
allowance.
2. During review of a commercial electrical project, the drawings show
one service size while the electrical specifications indicate a different
service rating. What should the contractor do before submitting a final
proposal?
A. Automatically use the smaller service because it reduces cost
B. Identify the discrepancy, review the applicable design documents and
requirements, and obtain clarification through the appropriate project
procedure
C. Ignore the discrepancy because the utility company will resolve it after
construction begins
D. Price both services but install whichever is easier to obtain
,Answer: B
Rationale: Conflicting contract documents should be resolved before
construction or final pricing so the contractor can accurately establish
scope, cost, equipment requirements, and compliance obligations.
3. An electrical contractor is reviewing a bid package and discovers that
several major pieces of switchgear have unusually long lead times.
Which estimating and scheduling response is most appropriate?
A. Exclude the switchgear from the estimate until construction starts B.
Identify the equipment as a procurement risk, verify specifications and
approved manufacturers, account for escalation and delivery requirements,
and coordinate procurement with the construction schedule
C. Assume the equipment will be available from local stock
D. Substitute smaller equipment automatically to shorten the schedule
Answer: B
Rationale: Long-lead equipment can affect both cost and project
completion, so the contractor should identify the risk early and coordinate
procurement, approvals, fabrication, and delivery with the schedule.
4. A contractor is estimating a project where the electrical scope is not
fully defined. Which approach provides the strongest protection
against unexpected costs?
, A. Assume all undefined work will be performed at no cost
B. Clearly identify assumptions, exclusions, allowances, clarifications, and
scope limitations in the proposal
C. Exclude all uncertain work without informing the owner
D. Add an arbitrary percentage without documenting the reason
Answer: B
Rationale: Clearly documented assumptions, exclusions, allowances, and
clarifications establish the contractor's understanding of incomplete scope
and reduce later disputes.
5. An electrical contractor calculates direct project costs of $420,000 and
estimates overhead at $63,000. What is the total cost before profit?
A. $357,000
B. $420,000
C. $483,000
D. $525,000
Answer: C
Rationale: Total cost before profit is the sum of direct cost and overhead,
so $420,000 + $63,000 = $483,000.
