Construction Specifications Institute Updated CDT Exam Questions and Answers by mitchell

Within CSI’s framework for contract documents, the term “Agreement” (capitalized) has a specific meaning. It refers to the formal written contract for construction between the Owner and the Contractor.

CSI describes the typical structure of the contract documents as including:

The Agreement between Owner and Contractor (such as AIA A101 or similar),

The Conditions of the Contract (General and Supplementary Conditions),

Drawings, Specifications, and Addenda,

And other documents listed in the Agreement.

The Agreement sets out key commercial terms (contract sum, contract time, identification of the work, list of contract documents, progress payments, etc.) and binds the owner and contractor to the Conditions of the Contract and the remainder of the documents.

Why the other options are not correct:

A. Agreement between the owner and the architect/engineer – This is usually a separate professional services agreement (often titled Owner–Architect Agreement or similar) and is not what CSI and AIA mean by “the Agreement” within the construction contract set.

B. The general conditions of the contract for construction – The General Conditions are a separate document; they become part of the contract when they are incorporated by reference in the Agreement, but they are not themselves “the Agreement.”

D. Agreement between the contractor and the subcontractor – This is a separate subcontract document, not part of the owner–contractor contract set defined in the project manual.

CSI’s practice material on contract formation and document relationships consistently identifies “the Agreement” as the contract between the Owner and the Contractor, hence Option C is correct.

Comprehensive and Detailed Explanation (CSI-aligned, paraphrased)

In CSI’s project delivery guidance, constructability reviews are described as a structured way to have construction-experienced professionals—often contractors, CMs, or experienced field personnel—review the design during planning or design phases to determine:

Whether the design can be built efficiently and safely

How site conditions, constraints, and logistics will affect means and methods

Potential cost, schedule, and sequencing issues arising from unique or complex aspects of the project

Constructability reviews are especially valuable when:

The site is constrained (tight urban sites, limited access, nearby sensitive structures)

There are unusual ground, environmental, or logistical conditions

The work involves complex staging, phasing, or access issues

Option C. The site presents unusual challenges and constraints is therefore the clearest trigger for a constructability review, because it directly ties to the need to evaluate how the physical and logistical realities of the site affect construction feasibility, cost, and sequence.

Why the other options are less appropriate:

A. The client is unfamiliar with this type of project.This calls for more owner education, clearer communication, and perhaps additional planning or programming support—not specifically a constructability review. The core need is understanding, not constructability.

B. The project team consists of multiple new members.That suggests a need for team alignment, clarification of roles, and communication protocols. While new team members may benefit from constructability input, the main justification for a formal constructability review is project/site complexity, not simply team turnover.

D. The contractor is unable to commit to original schedule.This is a procurement or scheduling problem, often addressed through rescheduling, negotiation, or possibly re-bid. Constructability reviews are proactive during design; schedule commitment issues often arise later and are handled with different tools (e.g., schedule analysis, changes, resequencing).

Comprehensive and Detailed Explanation From Exact Extract (CSI-based)

CSI distinguishes between competitive bidding and negotiated procurement:

Competitive bidding: multiple contractors submit sealed bids based on a complete set of contract documents. Award is usually based primarily on lowest responsive, responsible bid, especially in public work.

Negotiated procurement (negotiated contract): the owner selects one contractor (sometimes a small shortlist) and negotiates price, scope, and terms directly rather than relying on competitive bidding.

CSI notes that negotiated contracts are most often used in the private sector, where owners:

Have ongoing relationships with certain contractors,

Value qualifications, performance history, and trust,

May have complex or fast-track projects where early contractor involvement is desired.

Thus, negotiations typically take the place of bidding when there is a pre-existing relationship and trust between the owner and contractor and the owner chooses to negotiate rather than seek competitive bids. That aligns directly with Option D.

Why the other options are incorrect:

A. When exact quantities of work cannot be determined.When quantities are uncertain, a unit-price contract or allowances may be used, but the contractor may still be selected by competitive bidding. Uncertain quantities do not by themselves require a negotiated contract.

B. When a publicly funded project's lowest bid exceeds the budget.For public work, procurement is usually governed by statute. If bids exceed the budget, the typical actions are rebidding, revising scope, or obtaining additional funding—not simply switching to negotiation with one bidder.

C. When the contractor has defaulted on insurance premiums.Insurance problems are a responsibility/qualification issue, not a reason for negotiation to replace bidding. In fact, such a contractor may be deemed not responsible, and thus ineligible for award.

Under the typical CSI-aligned project delivery framework, additional time and money are generally justified when:

The owner (or A/E as owner’s agent) changes the work or otherwise causes delay (e.g., active interference, late decisions, design changes).

There are unforeseen conditions beyond the control of both owner and contractor, where the contract documents anticipated “normal” conditions instead.

Other compensable events defined in the Conditions of the Contract occur (e.g., certain force majeure events, if provided for).

However, the contractor is responsible for correcting defective or nonconforming work at no increase in contract sum or time (except where the defect is caused by others). CSI-based guidance on construction phase services and contract administration explains that:

Defective work (work not in accordance with the contract documents) must be removed, replaced, or corrected by the contractor at the contractor’s expense.

Any extra time and cost arising from correcting such defective work is not a valid basis for a change order or a claim for increased compensation or time extension.

If the contractor’s own documentation shows that the extra cost and time are due to defective work needing repair, the A/E has a clear basis—consistent with the Conditions of the Contract—to reject the claim. That aligns directly with Option D.

Why the other options do not support rejecting the claim:

A. Active interference by the owner – Owner-caused interference is typically a valid ground for a time and possibly cost adjustment, not grounds for rejection.

B. Conditions beyond the control of the contractor or owner – Unforeseen conditions are exactly the type of situation that may justify a claim, depending on the contract language.

C. The A/E modified the contract documents – A/E-issued changes (such as change orders or certain clarifications) often result in compensable changes if they add work or cause delay.
