Construction & Project Delivery: NPPE Practice Questions

16 free National Professional Practice Examination (NPPE) practice questions on construction & project delivery, covering construction contracts, tendering, bonds and liens, project delivery methods, and the engineer's role administering the work. Each question shows the correct answer and a plain-language explanation so you understand the reasoning, not just the letter.

1.Which project delivery method has the owner contracting directly with the various trades instead of hiring a general contractor, leaving the owner exposed to the risk of increased costs?

  • A.Design-build
  • B.Construction management
  • C.Design-bid-build
  • D.Public-private partnership (P3)
Reveal answer & explanation

Correct answer: B. Construction management

In construction management, the owner hires the trades directly rather than a general contractor, so the owner carries the risk of cost increases. Design-bid-build uses a contractor to build a completed design, and design-build has one party both design and build.

2.A 'holdback' under provincial lien legislation works by having the owner:

  • A.Pay the general contractor in full up front to speed up the project
  • B.Retain a percentage (e.g., 10%) of each progress payment until the lien period expires, to protect unpaid subcontractors and suppliers
  • C.Refuse to pay any invoices until the project is fully complete
  • D.Deposit the entire contract value into a trust account before work begins
Reveal answer & explanation

Correct answer: B. Retain a percentage (e.g., 10%) of each progress payment until the lien period expires, to protect unpaid subcontractors and suppliers

A holdback (retainage) requires the owner to hold back a set percentage of each progress payment (commonly 10%) until the project is complete and the lien period passes. It gives unpaid subcontractors and suppliers a fund to claim against if they file a lien.

3.In a fixed-price (lump sum) construction contract, which standard CCDC document is most commonly used?

  • A.CCDC 2
  • B.CCDC 3
  • C.CCDC 4
  • D.CCDC 5
Reveal answer & explanation

Correct answer: A. CCDC 2

CCDC 2 is the standard form fixed-price (stipulated price) contract. CCDC 3 is the standard cost-plus contract and CCDC 4 is the standard unit price contract.

4.The primary purpose of a construction (builders' or mechanics') lien is to:

  • A.Allow owners to legally hold back money from contractors indefinitely
  • B.Provide security so that those who supply labour and materials get paid
  • C.Let engineers and geoscientists finish projects faster
  • D.Guarantee a contractor a minimum level of profit
Reveal answer & explanation

Correct answer: B. Provide security so that those who supply labour and materials get paid

A lien facilitates credit in the construction industry and provides security for payment for labour and materials. It places a charge against the property, making it difficult to sell, until those who did the work are paid.

5.A performance bond, used to guarantee a contractor's performance of a construction contract, is generally issued for an amount equal to approximately:

  • A.10% of the contract value
  • B.25% of the contract value
  • C.50% of the contract value
  • D.100% of the contract value
Reveal answer & explanation

Correct answer: C. 50% of the contract value

A performance bond, in which the surety guarantees the contractor's performance, is generally about 50% of the contract value. By contrast, a bid bond is generally about 10% of the contract value.

6.During a project, a delay occurs that extends completion but for which the contractor is NOT contractually entitled to recover money, although the completion date can be extended. This is known as a(n):

  • A.Compensable delay
  • B.Excusable delay
  • C.Concurrent delay
  • D.Constructive acceleration
Reveal answer & explanation

Correct answer: B. Excusable delay

An excusable delay can extend the completion date but is not compensable (no money is recovered). A compensable delay entitles the party to recover damages. Items must be on the critical path to qualify for a time extension.

7.Bid shopping is considered unethical because:

  • A.It reduces competition
  • B.Price negotiations occur after the tender closes, undermining the bidding process
  • C.It always results in lower quality work
  • D.It is illegal in all provinces
Reveal answer & explanation

Correct answer: B. Price negotiations occur after the tender closes, undermining the bidding process

Bid shopping happens when price negotiations happen after the tender closes, which undermines the fair bidding process.

8.Arbitration is preferred over litigation because:

  • A.It is always binding
  • B.It is less costly, takes less time, and is less public
  • C.The arbitrator must be a lawyer
  • D.It always favors the plaintiff
Reveal answer & explanation

Correct answer: B. It is less costly, takes less time, and is less public

Arbitration is used because it is often less costly, takes less time, and is less public than litigation.

9.A "construction lien" allows:

  • A.The owner to sue the contractor for defects
  • B.Contractors, subcontractors, and suppliers to secure payment by encumbering the property
  • C.The municipality to halt construction
  • D.The architect to take ownership of the project
Reveal answer & explanation

Correct answer: B. Contractors, subcontractors, and suppliers to secure payment by encumbering the property

A construction lien is a legal claim registered against a property by a contractor, subcontractor, or supplier who has not been paid for work or materials.

10."Substantial completion" in construction triggers:

  • A.Final payment to the contractor
  • B.Release of holdback after the lien period and start of the warranty period
  • C.Transfer of title to the contractor
  • D.Automatic closure of all liens
Reveal answer & explanation

Correct answer: B. Release of holdback after the lien period and start of the warranty period

Substantial completion means the work is sufficiently complete for its intended use. It triggers the release of holdback (after the lien period expires) and starts the warranty period.

11.A "performance bond" guarantees that:

  • A.The contractor will be paid for all work
  • B.The contractor will complete the work according to contract terms
  • C.The owner will provide timely payments
  • D.Sub-contractors will receive all materials on time
Reveal answer & explanation

Correct answer: B. The contractor will complete the work according to contract terms

A performance bond is a surety bond guaranteeing the contractor will complete the work per the contract. If the contractor defaults, the surety may complete the work or pay damages.

12.In a CCDC 2 contract, the consultant (engineer/architect) serves as:

  • A.The contractor's supervisor
  • B.A neutral contract administrator between owner and contractor
  • C.The owner's legal counsel
  • D.The project's financial auditor
Reveal answer & explanation

Correct answer: B. A neutral contract administrator between owner and contractor

Under CCDC 2, the consultant acts as a neutral administrator: reviewing payment applications, interpreting contract documents, issuing certificates, and making initial decisions on disputes.

13.Fair tendering requires:

  • A.Awarding the contract to the lowest bidder in all cases
  • B.Treating all bidders equally, not disclosing bid information, and evaluating objectively
  • C.Only inviting pre-qualified contractors to bid
  • D.Negotiating with all bidders after tender close
Reveal answer & explanation

Correct answer: B. Treating all bidders equally, not disclosing bid information, and evaluating objectively

Fair tendering requires equal treatment of all bidders, confidentiality of bid information, objective evaluation, and no bid shopping or improper negotiations after tender close.

14.A "bid bond" is submitted with a tender to:

  • A.Guarantee payment to sub-contractors
  • B.Guarantee the bidder will enter into the contract if awarded
  • C.Ensure the project meets building codes
  • D.Protect the contractor from owner default
Reveal answer & explanation

Correct answer: B. Guarantee the bidder will enter into the contract if awarded

A bid bond guarantees the bidder will enter into the contract if awarded. If the bidder refuses, the surety pays the difference between that bid and the next acceptable bid.

15."Design-build" project delivery differs from "design-bid-build" in that:

  • A.The owner is responsible for both design and construction
  • B.A single entity is responsible for both design and construction
  • C.The design is completed after construction begins
  • D.There is no tendering process
Reveal answer & explanation

Correct answer: B. A single entity is responsible for both design and construction

In design-build, a single entity handles both design and construction, providing single-point responsibility. In design-bid-build, these are separate sequential phases with different parties.

16.A "change order" in construction must be:

  • A.Verbally agreed upon between the parties
  • B.Written, authorized, and agreed upon before additional work is performed
  • C.Approved by the municipal building inspector
  • D.Filed with the provincial construction authority
Reveal answer & explanation

Correct answer: B. Written, authorized, and agreed upon before additional work is performed

A change order must be a written agreement between the owner and contractor documenting changes to scope, price, or schedule, authorized before the additional work is performed.
