CEC Material Pricing & Escalation 3 — Questions and Answers
Question 1: Which published resource is most commonly used by US construction estimators to benchmark current material and labor cost indices?
- Dodge Data & Analytics
- Engineering News-Record (ENR) (Correct answer)
- Bureau of Labor Statistics CPI-U
- RS Means CostWorks
Correct answer: Engineering News-Record (ENR)
The Engineering News-Record (ENR) Construction Cost Index and Building Cost Index are the most widely referenced industry benchmarks for tracking construction cost trends.
Question 2: A fixed-price contract for structural steel is signed in January at $1,800/ton. A futures hedge is placed at $1,850/ton. Steel rises to $2,100/ton at delivery. What is the net effective cost per ton?
- $1,800/ton
- $1,850/ton (Correct answer)
- $2,100/ton
- $2,050/ton
Correct answer: $1,850/ton
The futures hedge locks in the purchase price at $1,850/ton regardless of the spot price at delivery, making the net effective cost $1,850/ton.
Question 3: When estimating material costs for a project scheduled to start in 18 months, which approach provides the MOST reliable cost basis?
- Last year's invoice prices without adjustment
- Current quotes with an escalation factor applied forward (Correct answer)
- Parametric data from a similar project 5 years ago
- Published labor rates only
Correct answer: Current quotes with an escalation factor applied forward
Current quotes adjusted forward with an escalation factor account for both current market conditions and anticipated price trends over the 18-month period.
Question 4: What does a 'base date' refer to in the context of a construction cost escalation clause?
- The date the project is substantially complete
- The reference date from which price changes are measured (Correct answer)
- The date the owner approves the budget
- The date of the last pay application
Correct answer: The reference date from which price changes are measured
The base date is the reference point — typically the bid date or contract execution date — from which escalation is calculated.
Question 5: An estimator is pricing copper wire for an electrical bid. Copper spot price is $4.10/lb today, but the contract period is 12 months. The estimator builds in a 6% annual escalation. What is the mid-project average price used for estimating?
- $4.10/lb
- $4.22/lb (Correct answer)
- $4.35/lb
- $4.34/lb
Correct answer: $4.22/lb
At 6% annual escalation, the price at 12 months is $4.35/lb; the mid-project average (at 6 months, or 3% increase) is $4.10 × 1.03 ≈ $4.22/lb.
Question 6: Which contract type provides the owner with the LEAST protection against material price escalation risk?
- Cost-plus-fee contract
- Guaranteed maximum price (GMP) contract (Correct answer)
- Fixed-price lump sum contract with no escalation clause
- Unit price contract with escalation provisions
Correct answer: Guaranteed maximum price (GMP) contract
Under a GMP contract, the owner bears no cost above the maximum, but if the contractor included high escalation contingency in the GMP, the owner may overpay relative to actual costs — a cost-plus contract exposes the owner directly to all cost increases.
Question 7: A specification calls for Type I Portland cement at $120/ton. The estimator notes a current shortage is driving spot prices to $145/ton. What should the estimator do?
- Use the specification price of $120/ton as it is the contract basis
- Use the current market price of $145/ton and document the market condition (Correct answer)
- Average the two prices at $132.50/ton
- Substitute a cheaper alternative material
Correct answer: Use the current market price of $145/ton and document the market condition
Estimators must use current market prices and document conditions; using an outdated or theoretical price exposes the contractor to a budget shortfall.
