CPI Project Estimation & Cost Bidding 2 — Questions and Answers
Question 1: When preparing a bid for a large commercial installation, which document typically outlines the scope of work, materials, and performance requirements the installer must meet?
- Purchase order
- Specification sheet (Correct answer)
- Change order
- Bill of lading
Correct answer: Specification sheet
Specification sheets define the required materials, workmanship standards, and performance criteria that a bid must address.
Question 2: A contractor receives a request for proposal (RFP) with a tight submission deadline. What is the BEST first step before estimating costs?
- Submit a preliminary price immediately
- Perform a thorough site walk-through and scope review (Correct answer)
- Contact subcontractors for pricing only
- Copy the estimate from a similar past project
Correct answer: Perform a thorough site walk-through and scope review
A site walk-through and scope review ensures the estimate reflects actual conditions and avoids costly omissions.
Question 3: In project estimation, 'quantity takeoff' refers to which activity?
- Calculating labor overtime
- Measuring and counting all materials needed from project drawings (Correct answer)
- Estimating project duration
- Reviewing subcontractor invoices
Correct answer: Measuring and counting all materials needed from project drawings
Quantity takeoff is the process of measuring dimensions and counting items from blueprints to determine material quantities.
Question 4: Which type of estimate is typically used early in a project when design details are incomplete?
- Definitive estimate
- Parametric estimate (Correct answer)
- Detailed bottom-up estimate
- Bid estimate
Correct answer: Parametric estimate
Parametric estimates use statistical relationships between historical data and project parameters to estimate costs when full details are unavailable.
Question 5: A customer requests that an installer add extra outlets not included in the original bid. How should the installer handle this addition?
- Include it at no charge to maintain goodwill
- Issue a change order with revised pricing before performing the work (Correct answer)
- Complete the work and bill later
- Decline the request entirely
Correct answer: Issue a change order with revised pricing before performing the work
A change order documents scope changes and adjusts the contract price, protecting both the installer and the customer.
Question 6: What does a 'unit price contract' mean for an installer bidding on a project?
- The installer charges a flat fee for the entire project
- The installer is paid a set price per unit of work completed (Correct answer)
- The customer pays all material costs directly
- The contract is for one unit only
Correct answer: The installer is paid a set price per unit of work completed
Unit price contracts pay the installer a fixed rate per measured unit (e.g., per linear foot or per outlet installed), adjusting final cost based on actual quantities.
Question 7: When estimating labor costs for an installation project, which factor is MOST critical to account for?
- The owner's preferred brand of materials
- Crew productivity rates and local prevailing wages (Correct answer)
- The color scheme of the installation
- Equipment manufacturer recommendations
Correct answer: Crew productivity rates and local prevailing wages
Crew productivity rates and local wage scales directly determine labor cost accuracy in any installation estimate.
