- 1. Business Organization & Licensing
A construction business is organized as a corporation. If the corporation is sued and cannot pay a judgment, what is generally at risk?
- a.The personal homes and bank accounts of every shareholder
- b.The personal assets of the highest-paid officer only
- c.The assets owned by the corporation itself, not the shareholders' personal assets
- d.Nothing, because corporations cannot be sued
Answer: c
Explanation: A corporation is a separate legal entity from its owners (shareholders). This separation creates limited liability: creditors and judgments generally reach only the assets the corporation owns, and shareholders risk losing only what they invested — not their personal homes or savings. That protection can be lost only in unusual cases such as fraud or 'piercing the corporate veil.'
- 2. Estimating & Bidding
How many cubic yards of concrete are needed for a slab 27 ft long, 30 ft wide, and 4 inches thick?
- a.3.3 cubic yards
- b.6.7 cubic yards
- c.8.5 cubic yards
- d.10 cubic yards
Answer: d
Explanation: First convert thickness to feet: 4 in / 12 = 0.3333 ft. Volume in cubic feet = 27 x 30 x 0.3333 = 270 cubic feet. Convert to cubic yards by dividing by 27 (there are 27 cubic feet in a cubic yard): 270 / 27 = 10 cubic yards. Getting units consistent — feet for all three dimensions — is the key step.
- 3. Contracts & Contract Law
Under the Statute of Frauds, which of the following is generally required to be in writing to be enforceable?
- a.A one-hour verbal agreement to sweep a job site
- b.A casual promise to lend a friend a hammer
- c.An agreement to buy lunch for the crew
- d.A contract for the sale of land or an interest in real property
Answer: d
Explanation: The Statute of Frauds requires certain categories of contracts to be in writing and signed to be enforceable — most notably contracts for the sale of land or interests in real property, and agreements that cannot be performed within one year. This is why construction and real-property agreements are documented in writing. Minor, short, everyday arrangements are not covered.
- 4. Financial Management & Accounting
A contracting company has current assets of $240,000 and current liabilities of $120,000. What is its current ratio?
- a.0.5 to 1
- b.1.2 to 1
- c.2.0 to 1
- d.12 to 1
Answer: c
Explanation: Current ratio = current assets / current liabilities = $240,000 / $120,000 = 2.0. A ratio of 2.0 means the company has $2 of short-term assets for every $1 of short-term debt, which generally indicates healthy short-term liquidity. Sureties and lenders watch this ratio closely; a ratio below 1.0 signals the company may struggle to pay near-term obligations.
- 5. Safety & OSHA
OSHA requires that a trench or excavation be protected by sloping, shoring, or a protective (trench) box once it reaches what depth?
- a.3 feet
- b.5 feet
- c.10 feet
- d.15 feet
Answer: b
Explanation: Under OSHA's excavation standard (29 CFR 1926.652), a protective system — sloping/benching, shoring, or a trench box (shield) — is generally required for trenches 5 feet deep or greater (unless the excavation is entirely in stable rock). A registered professional engineer must design protection for trenches deeper than 20 feet. Cave-ins are frequently fatal, so a competent person must inspect excavations daily.
- 6. Employment & Labor Law
What is the purpose of Form I-9 that a contractor completes for each new hire?
- a.To calculate the employee's overtime rate
- b.To register the employee with the local building department
- c.To order the employee's personal protective equipment
- d.To verify the employee's identity and legal authorization to work in the United States
Answer: d
Explanation: The federal Form I-9 is used to verify each new employee's identity and their authorization to work in the United States, as required by immigration law. Employers must complete and retain an I-9 for every employee and review acceptable documents. It is separate from tax forms (like the W-4) and from any safety, permitting, or payroll-rate functions.

A South Carolina contractor holds a commercial license issued by the Contractor's Licensing Board (CLB). What other work does that license also authorize?
- a.Only commercial work; residential building is entirely prohibited
- b.Electrical utility transmission work statewide
- c.Only federally funded projects
- d.Residential work, because the CLB commercial license also authorizes residential building
Answer: d
Explanation: In South Carolina a CLB commercial license also authorizes the holder to perform residential building work, so a commercially licensed general contractor does not need a separate residential builder's license to build homes. The reverse is not true - a residential-only credential does not authorize commercial work.

A contract clause setting a fixed dollar amount per day of delay, agreed in advance as a reasonable estimate of the owner's loss, is called:
- a.Liquidated damages
- b.A mechanic's lien
- c.Retainage
- d.A change order
Answer: a
Explanation: Liquidated damages are a pre-agreed, fixed sum (often per day of delay) that represents a reasonable estimate of hard-to-measure losses. To be enforceable the amount must be a genuine estimate, not a penalty; retainage and change orders address different issues.

The critical path in a project schedule is best described as the path that:
- a.Carries the most float, giving the schedule flexibility
- b.Is the shortest route through the network
- c.Is the longest chain of dependent activities, has zero float, and sets the shortest possible completion time
- d.Contains the fewest individual tasks
Answer: c
Explanation: The critical path is the longest chain of dependent activities. Because no other path is longer, it fixes the earliest the project can finish, and every activity on it has zero float, so any slip pushes out completion day for day.

The gross FUTA (federal unemployment) rate is 6.0% on the first $7,000 of each employee's wages. With the full credit for state unemployment tax paid on time, what is the effective FUTA rate?
- a.0.6%
- b.5.4%
- c.6.0%
- d.1.45%
Answer: a
Explanation: The full 5.4% state credit reduces the 6.0% gross rate to an effective 0.6% (a maximum of about $42 per employee per year). FUTA is paid entirely by the employer and is never withheld from the employee.
