CC Estimating and Bidding 1 — Questions and Answers
Question 1: Which type of estimate is typically the most detailed and accurate for a construction project?
- Conceptual estimate
- Schematic estimate
- Definitive estimate (Correct answer)
- Order-of-magnitude estimate
Correct answer: Definitive estimate
A definitive estimate is prepared from complete construction documents and provides the highest level of accuracy, typically within ±5-10%.
Question 2: When preparing a bid, which document outlines the rules, conditions, and procedures contractors must follow during the bidding process?
- Scope of work
- Instructions to Bidders (Correct answer)
- General Conditions
- Specifications
Correct answer: Instructions to Bidders
Instructions to Bidders is the document that details the rules, submission requirements, and procedures all bidders must follow when preparing and submitting their bids.
Question 3: A contractor's overhead costs that cannot be directly attributed to a single project are called:
- Direct costs
- General overhead (Correct answer)
- Job site overhead
- Material costs
Correct answer: General overhead
General overhead (also called general and administrative overhead) covers costs like office rent, utilities, and administrative salaries that support the business but aren't tied to one project.
Question 4: What does the term 'quantity takeoff' refer to in construction estimating?
- Removing excess materials from a job site
- Measuring and listing all materials needed for a project (Correct answer)
- Calculating the profit margin on a bid
- Estimating the number of workers required
Correct answer: Measuring and listing all materials needed for a project
A quantity takeoff is the process of measuring and listing all materials, labor, and equipment quantities needed for a project based on the plans and specifications.
Question 5: Which bidding method requires contractors to submit sealed proposals that are opened publicly at a designated time?
- Negotiated bid
- Design-build bid
- Competitive sealed bid (Correct answer)
- Cost-plus bid
Correct answer: Competitive sealed bid
Competitive sealed bidding requires all bids to be submitted in sealed envelopes and opened publicly at a specified time, ensuring fairness and transparency in the selection process.
Question 6: A bid bond protects the project owner by ensuring that:
- The contractor completes the project on time
- The contractor will enter into a contract if awarded the bid (Correct answer)
- All subcontractors are paid
- The project meets quality standards
Correct answer: The contractor will enter into a contract if awarded the bid
A bid bond guarantees that if the contractor is awarded the project, they will enter into a formal contract; if they refuse, the bond compensates the owner for the cost of re-bidding.
Question 7: In construction estimating, what is a 'contingency allowance' used for?
- Paying subcontractor invoices early
- Covering unforeseen costs or risks not identified in the estimate (Correct answer)
- Reducing the total bid price to win the job
- Covering the cost of project insurance
Correct answer: Covering unforeseen costs or risks not identified in the estimate
A contingency allowance is a percentage added to an estimate to cover unforeseen conditions, risks, or uncertainties that may arise during construction.
