D. Owner
答案：C
解題說明：
Comprehensive and Detailed Explanation From Exact Extract (CSI-based)
According to CSI's Project Delivery Practice Guide and CDT body of knowledge, the Contractor is typically required-by the conditions of the Contract-to maintain record drawings during construction.
These are sometimes called "as-built" or "marked-up" drawings.
CSI explains that:
* The Contractor must keep on site a current set of drawings and, as the work progresses, mark changes, deviations, and concealed conditions that differ from the original contract drawings.
* This responsibility is usually stated in the General Conditions and/or Division 01, and is part of the contractor's obligation to provide Project Record Documents at closeout.
* At the end of the project, these contractor-maintained record drawings and related record information are typically delivered to the Architect/Engineer and then to the Owner as part of closeout, but the party maintaining them during the project itself is the Contractor.
The Architect uses the contractor's record information to prepare formal record documents only if required by the contract, but the day-to-day updating and maintenance during construction is assigned to the Contractor in standard CSI-aligned practice.
Relevant CSI concepts (paraphrased):
* CSI Project Delivery Practice Guide - sections on "Construction Phase" and "Project Record Documents" explaining that the contractor keeps a set of marked-up record drawings during the work.
* CSI CDT Study Materials - topic on roles and responsibilities for record documents and closeout.
問題 #73
What is the basis of payment for a contract negotiated between an owner and a contractor for a fixed price?
A. Cost-plus-fee
B. Unit price
C. Cost-plus-fee with guaranteed maximum price
D. Stipulated sum
答案：D
解題說明：
CSI's treatment of methods of payment / contract pricing (as used in standard owner-contractor agreements and CDT content) includes several common bases of payment:
* Stipulated Sum (Lump Sum)
* The contractor agrees to provide the work for a single fixed price.
* The price does not change except through formal changes to the work (change orders).
* This is the classic "fixed-price" contract form.
* Unit Price
* The contractor is paid based on measured quantities of work completed multiplied by agreed unit rates.
* Final cost depends on actual quantities installed, not a single fixed total.
* Cost-Plus-Fee
* The owner reimburses actual cost of the work (labor, materials, equipment, etc.) plus a fee (fixed or percentage) as contractor's compensation.
* The final cost is not fixed; it varies with actual costs incurred.
* Cost-Plus-Fee with Guaranteed Maximum Price (GMP)
* A variation of cost-plus where the total reimbursable cost plus fee is capped at a guaranteed maximum.
* Still not the same as a straightforward fixed lump sum; the basis is cost reimbursement up to a cap.
The question specifically asks: "for a fixed price." In CSI and standard contract terminology, "fixed price"
= "stipulated sum" (or lump sum). That is:
* The owner and contractor negotiate a single dollar amount for the entire scope of work;
* The contractor's compensation is that stipulated sum, adjusted only by approved changes.
Why the other options are not correct:
* B. Unit price - The total cost is not fixed at the time of contracting; it depends on actual installed quantities.
* C. Cost-plus-fee - Costs are reimbursed; final price is open-ended and therefore not fixed.
* D. Cost-plus-fee with guaranteed maximum price - This sets a cap, but the actual final cost is not a single fixed price; it is "actual cost plus fee" up to the GMP.
Therefore, the correct basis of payment for a fixed-price contract is Stipulated sum (Option A), consistent with CSI's classification of contract types and standard owner-contractor agreements.
Key CSI References (titles only, no links):
* CSI Project Delivery Practice Guide - sections on "Basis of Payment" and contract pricing methods (stipulated sum, unit price, cost-plus, GMP).
* CSI CDT Body of Knowledge - Contract Types and Methods of Payment.
* Standard owner-contractor agreements discussed in CSI materials (e.g., stipulated sum as the fixed- price form).
問題 #74
During the schematic design phase, a contingency line item in the estimate would be included to cover which of the following?
A. Unknown factors
B. Allowances
C. Alternates
D. Unit prices
答案：A
解題說明：
In CSI-based project cost planning, contingency is defined as an amount added to an estimate or budget to cover uncertainties and unknowns that cannot yet be clearly defined at the current level of design development.
CSI's practice guides and CDT materials explain (paraphrased):
* In early design phases, such as schematic design, the design is only partially developed. Important elements are still undecided, and system configurations may change. Because of this, the cost estimate is inherently less precise.
* A contingency line item is therefore included to cover:
* Incomplete design information,
* Potential scope refinement,
* Normal estimating uncertainties, and
* Other unknown factors at that stage.
* As the project moves into design development and later into the construction documents phase, the design becomes more complete and the uncertainty decreases, so contingency percentages typically decrease.
By contrast, CSI differentiates contingency from other estimating tools:
* Allowances: Specific sums in the contract for known-but-not-fully-defined items (e.g., "flooring allowance of X per m"). These are identified items with placeholder values, not general unknowns.
* Unit prices: Agreed rates for measuring work (e.g., $/m of rock excavation) used when quantities are uncertain, but scope categories are known and clearly described in the documents.
* Alternates: Defined options requested by the owner (additive or deductive) for comparison and selection-again, specifically described items, not "unknowns." Because the question specifically references the schematic design phase and asks what the contingency line item covers, the CSI-aligned answer is "Unknown factors" - Option C.
Why the other options are incorrect:
* A. Allowances - These are separate, explicit line items in the estimate or specifications and are not what contingency is intended to cover.
* B. Unit prices - These deal with agreed rates for work whose quantities may vary, not with broad early- phase uncertainty.
* D. Alternates - Alternates are specifically described choices requested for comparison; they are priced individually, not absorbed into contingency.
Key CSI-aligned references (no links):
* CSI Project Delivery Practice Guide - sections on cost planning and contingencies by phase.
* CSI CDT Body of Knowledge - definitions and uses of contingency, allowances, unit prices, and alternates in estimating.
