Started at

Set a timer for 330 minutes and do not stop it. Running over is the commonest way a prepared candidate fails, and the only place you can find that out safely is here.
Mark one answer for each question on the answer sheet.
Answer every question. There is no penalty for a wrong answer. A blank is a guaranteed zero and a guess is not.
Flag anything you are unsure of as you go. When you mark the paper, a question you flagged and got right is worth as much of your attention as one you got wrong - you do not yet know it, you guessed it.
When the timer runs out, turn to the Answers section at the back of this file. Mark the paper against the quick-reference key first, fill in the score table, and only then read the worked explanations.

Paper #2

115 questions. 330 minutes.

1

How far is station 18+40 from station 6+90?

A115 feet
B11.5 feet, since the difference is measured in stations rather than feet
C1,150 feet
D2,530 feet

2

What must an owner do before calling on a performance bond?

ATerminate the contract and complete the work before notifying the surety
BFollow the bond's own conditions, including notice and declaration of default
CObtain the contractor's written agreement that it has defaulted
DExhaust the retainage held before making any claim

3

From what event does the deadline to record a lien usually run?

AThe date the claimant's invoice became overdue
BThe date on which the owner first took occupancy of any part of the building
CLast furnishing of labour or material, or completion as the statute defines it
DThe date the claimant's subcontract was executed

Worked explanations

The paper carries one for every question, at the back. These are the three above.

Q1 C Ch. 3: Site Construction

Answer: C - 1,150 feet

Because Convert each station to feet and subtract. NASCLA Guide ch. 13

1,840 - 690 = 1,150 feet.

Where the other options lead

A.Misplaces a decimal. 115 feet is a tenth of the correct distance.
B.Leaves the answer in stations. 11.5 stations is 1,150 feet, and the question asks for feet.
D.Adds the two stations. Distance between two points is the difference, not the sum.

Q2 B Ch. 1: Procurement and Contracting Requirements

Answer: B - Follow the bond's own conditions, including notice and declaration of default

Because Modern bonds set conditions precedent: notice to the contractor and surety, a conference where required, formal declaration of default and termination, and agreement to pay the balance of the contract price to the surety or its completion contractor. Missing a step can defeat the claim. NASCLA Guide ch. 5

Where the other options lead

A.Completes first. Completing before involving the surety removes its options and prejudices its position, which is a common defence.
C.Requires the contractor's agreement. A defaulting contractor rarely agrees, and the bond does not require it.
D.Exhausts retainage first. Retainage is applied to the cost of completion but is not a precondition.

Q3 C Ch. 1: Procurement and Contracting Requirements

Answer: C - Last furnishing of labour or material, or completion as the statute defines it

Because Statutes run the clock from the claimant's last day of work or delivery, or from completion, cessation or a recorded notice of completion. Returning to do warranty or punch work generally does not restart it, which is a trap for the unwary. NASCLA Guide ch. 8

Where the other options lead

A.Uses the invoice. Payment terms are a contract matter and do not set the statutory clock.
B.Uses occupancy. Occupancy may evidence completion in some states and is not itself the trigger.
D.Uses the contract date. The right arises from the work, so the clock runs from the work.
