1. A commercial electrical contractor is preparing a bid for a complex
facility containing a new service, distribution equipment, motors,
lighting, emergency power, fire alarm, communications, and specialty
equipment. Which estimating procedure provides the most
dependable basis for establishing the contract price?
A. Estimate only the major electrical equipment and add a small percentage
for everything else
B. Multiply the building's floor area by an average electrical cost from a
previous project
C. Review the complete contract documents, perform detailed quantity
takeoffs, calculate labor and material requirements, evaluate equipment
, and subcontract costs, and include appropriate indirect costs, overhead,
risk, and profit
D. Base the bid entirely on the lowest material supplier quotations
Answer: C
Rationale: A reliable electrical estimate requires comprehensive evaluation
of the project's scope, quantities, labor productivity, materials, equipment,
indirect expenses, schedule conditions, risk, overhead, and desired profit.
2. An electrical contractor discovers that the electrical drawings specify a
2,000-ampere service while another contract document indicates a
1,600-ampere service. What is the most appropriate action before
finalizing the bid?
A. Always use the smaller service to reduce the bid
B. Identify the discrepancy and obtain appropriate clarification through the
contract administration process
C. Select whichever service is easiest to purchase
D. Ignore the conflict because the utility will determine the final size
Answer: B
Rationale: Conflicting contract requirements should be resolved before
pricing and construction so the contractor understands the intended scope
and can provide an accurate proposal.
, 3. A contractor is estimating a project with several pieces of electrical
equipment having long manufacturing lead times. Which practice is
most effective for managing this risk?
A. Wait until installation begins before ordering the equipment B.
Identify long-lead items during estimating, verify procurement
requirements, and incorporate submittal, approval, manufacturing, and
delivery durations into the project schedule
C. Exclude the equipment from the bid
D. Assume the equipment will always be locally stocked
Answer: B
Rationale: Early identification and scheduling of long-lead equipment helps
prevent procurement delays from affecting construction activities and
project completion.
4. A contractor receives incomplete specifications for a specialized
electrical system. Which proposal practice provides the strongest
protection against an inaccurate scope interpretation?
A. Assume every possible feature is included without documentation B.
Clearly state assumptions, exclusions, allowances, clarifications, and
qualifications in the proposal
C. Exclude the entire system without notifying the owner
D. Add an arbitrary contingency without identifying its purpose
, Answer: B
Rationale: Documented assumptions and exclusions communicate the
contractor's understanding of uncertain scope and provide a clear basis for
pricing and subsequent contract administration.
5. An electrical project has direct costs of $575,000 and project overhead
of $86,250. What is the total cost before profit?
A. $488,750
B. $575,000
C. $661,250
D. $747,500
Answer: C
Rationale: The total cost before profit is $575,000 + $86,250, which equals
$661,250.
6. A contractor's estimated direct project cost is $800,000. The
contractor wants a 15% markup on cost. What is the resulting selling
price before considering any other adjustments?
A. $815,000
B. $920,000
C. $935,000
D. $1,000,000
