CSI Product Selection & Substitution 2 — Questions and Answers
Question 1: Under CSI standards, which party bears primary responsibility for evaluating whether a proposed substitution meets specification intent?
- The subcontractor proposing the substitution
- The architect or engineer of record (Correct answer)
- The product manufacturer's representative
- The construction manager
Correct answer: The architect or engineer of record
The architect or engineer of record is responsible for evaluating substitution requests to determine if they meet the design intent and specification requirements.
Question 2: Which MasterFormat section division most directly governs general substitution procedures applicable across all product categories?
- Division 01 – General Requirements (Correct answer)
- Division 02 – Existing Conditions
- Division 03 – Concrete
- Division 09 – Finishes
Correct answer: Division 01 – General Requirements
Division 01 – General Requirements contains Section 01 25 00 (Substitution Procedures), which establishes the process for all product substitutions on a project.
Question 3: A contractor submits a substitution request 45 days after award of contract. The specification allows substitutions only within 30 days after award. The architect should:
- Accept it because the difference is minor
- Reject it as untimely unless the owner grants an extension (Correct answer)
- Forward it to the engineer without comment
- Request the manufacturer submit directly
Correct answer: Reject it as untimely unless the owner grants an extension
Specifications set contractual deadlines for substitution requests, and submissions received after the stated period should be rejected unless the owner formally extends the deadline.
Question 4: What distinguishes a 'product substitution' from a 'product option' in CSI specification language?
- Options are changes the owner initiates; substitutions are contractor-initiated changes
- Options are pre-approved alternatives listed in the specification; substitutions require approval after bid (Correct answer)
- Options apply only to mechanical products; substitutions apply to architectural products
- Options require a specification addendum; substitutions do not
Correct answer: Options are pre-approved alternatives listed in the specification; substitutions require approval after bid
Product options are alternatives explicitly listed in the specification and pre-approved for use, while substitutions are proposed products not listed that require review and approval.
Question 5: When a specifier writes 'or approved equal' after a named product, which burden does this language place on the contractor?
- No burden — any product the contractor selects is automatically approved
- The contractor must demonstrate equivalency in quality, performance, and features (Correct answer)
- The contractor need only match the price of the named product
- The contractor must obtain approval only from the subcontractor, not the architect
Correct answer: The contractor must demonstrate equivalency in quality, performance, and features
The 'or approved equal' clause requires the contractor to prove the proposed product is equivalent in all material respects including performance, quality, and appearance.
Question 6: Which document type is specifically used to communicate an accepted substitution to all bidders before bid date?
- Request for Information (RFI)
- Addendum (Correct answer)
- Change Order
- Submittal transmittal
Correct answer: Addendum
An addendum is the only contract document that can formally modify specifications before bid date, ensuring all bidders have the same accepted substitution information.
Question 7: A substitution request includes test data showing the proposed product meets 90% of the specified performance value. Under standard CSI practice, the architect should:
- Accept it as substantially equivalent
- Reject it because it does not fully meet the specification (Correct answer)
- Approve it with a credit back to the owner for the difference
- Defer the decision to the contractor's testing laboratory
Correct answer: Reject it because it does not fully meet the specification
Products that do not fully meet specified performance requirements are not equivalent substitutions and should be rejected unless the specification explicitly allows a lower threshold.
