Question 1
The MOST accurate information for estimating the number of hours REQUIRED to perform a task comes from
Correct Answer: D
Rationale: Job cost records from previous similar projects are the gold standard for labor-hour estimating because they reflect real-world productivity under actual field conditions, including weather, crew experience, site access, interference, and learning curve effects. Manufacturer specs and plans give theoretical minimums; superintendent reports are useful but often incomplete or subjective. Only historical cost data consistently captures the true hours required for your specific crews and methods.

Question 2
For ease in estimating labor costs, work should be grouped by
Correct Answer: C
Rationale: Labor rates, crew composition, and productivity vary dramatically by activity (e.g., formwork vs. rebar placement vs. concrete pouring). Grouping by activity allows the estimator to apply the correct wage rates, crew sizes, and historical productivity factors to each line item. Grouping by material or equipment ignores the dominant driver of labor cost: the type of work being performed.

Question 3
A Unit Price Estimate consists of
Correct Answer: A
Rationale: A true unit-price estimate develops a complete cost (material + labor + equipment + subcontract + overhead + profit) for each defined unit of work (e.g., per CY of concrete, per SF of drywall). The total contract price is then quantity × unit price for all items. This is the standard bidding format for heavy-civil and many public works contracts.

Question 4
The general rule of law for interpreting an ambiguous provision of a contract is that it is
Correct Answer: A
Rationale: The doctrine of contra proferentem is a fundamental principle of contract law in virtually every U.S. jurisdiction. When contract language is unclear and the parties dispute its meaning, courts construe the ambiguity against the drafter as a penalty for failing to write clearly. This protects the non-drafting party who had no control over the wording.

Question 5
Who is responsible for preparing MSDS?
Correct Answer: C
Rationale: Under OSHA's Hazard Communication Standard (29 CFR 1910.1200), the chemical manufacturer or importer is required to evaluate hazards, prepare Safety Data Sheets (formerly MSDS), and provide them downstream. OSHA writes the regulation but does not create the SDS documents.
