CPI Project Estimation & Cost Bidding 3 — Questions and Answers
Question 1: An installer discovers unexpected site conditions (e.g., existing buried conduit) after the bid is awarded. What is the appropriate course of action?
- Absorb the extra cost to avoid conflict
- Notify the customer and submit a change order for differing site conditions (Correct answer)
- Stop work immediately and leave the site
- Hire additional labor without authorization
Correct answer: Notify the customer and submit a change order for differing site conditions
Differing site conditions are typically addressed through change orders that adjust scope and cost with customer approval.
Question 2: What is the purpose of including a contingency allowance in a project estimate?
- To increase profit margins
- To cover unforeseen costs and risks that may arise during the project (Correct answer)
- To reduce the bid price to win the contract
- To pay for design changes requested before the bid
Correct answer: To cover unforeseen costs and risks that may arise during the project
Contingency allowances provide a financial buffer for unpredictable events without requiring immediate scope changes.
Question 3: Which of the following BEST describes 'burden rate' in labor cost estimation?
- The cost of renting heavy equipment
- Additional costs beyond base wages, including taxes, insurance, and benefits (Correct answer)
- Overtime pay multiplier
- The markup applied to subcontractor costs
Correct answer: Additional costs beyond base wages, including taxes, insurance, and benefits
Burden rate represents the total employer cost per labor hour beyond base wages, including payroll taxes, workers' comp, and benefits.
Question 4: A CPI installer is bidding on a project that requires special tools not currently owned by the company. How should tool acquisition costs be treated in the estimate?
- Excluded, as tools are always the customer's responsibility
- Included as a direct project cost or amortized across projects if reusable (Correct answer)
- Listed as a contingency item only
- Added to the overhead category without disclosure
Correct answer: Included as a direct project cost or amortized across projects if reusable
Special tool costs must be captured in the estimate either as a direct cost or spread across projects if the tools will be reused.
Question 5: When comparing competitive bids, a general contractor notices one bid is significantly lower than all others. What is the MOST likely concern?
- The low bidder used superior materials
- The low bid may omit critical scope items or reflect poor quality (Correct answer)
- The low bidder negotiated better subcontractor rates
- All bids include identical scope
Correct answer: The low bid may omit critical scope items or reflect poor quality
An unusually low bid often signals missing scope, underestimated labor, or inferior materials that could lead to disputes or poor outcomes.
Question 6: What is 'bid shopping' and why is it considered unethical in the construction and installation industry?
- Comparing multiple vendor catalogs for materials
- Using one subcontractor's price to pressure others into lowering their bids (Correct answer)
- Soliciting multiple bids from general contractors
- Reviewing historical bid data for accuracy
Correct answer: Using one subcontractor's price to pressure others into lowering their bids
Bid shopping undermines fair competition by using confidential pricing to extract lower bids, violating trust and professional ethics.
Question 7: In installation project management, 'scope creep' most commonly leads to which financial problem?
- Reduced material waste
- Cost overruns because additional work is performed without contract adjustments (Correct answer)
- Faster project completion
- Lower subcontractor costs
Correct answer: Cost overruns because additional work is performed without contract adjustments
Scope creep adds work beyond the contracted scope without corresponding price increases, eroding profit margins.
