Post-Award Substitution Request for District-Standard HVAC Unit
A school district solicits bids for a cafeteria HVAC replacement. Specification Section 23 74 13 names Brand A rooftop unit, model RA-40, and states 'No substitutions will be accepted' because the district stocks Brand A filters and controls across 14 schools. Division 01 Section 01 25 00 includes a substitutions procedure requiring requests at least 10 days before bid opening. Twelve days after notice of award, the mechanical contractor submits a substitution request for Brand B model RB-42, citing equal 12.5 EER, $8,400 lower cost, and a 3-week shorter lead time. The contractor's bid used Brand B without an approved substitution. The district's facilities director asks whether the request can be approved administratively to protect the schedule, since the first day of school is in 14 weeks. The specified Brand A unit has a 10-week lead time; Brand B is 7 weeks. The contract documents include the standard 'or equal' language in Division 01, but the Section 23 74 13 no-substitutions clause is specific.
1. Evaluate the substitution request under the contract documents.

The request fails the procedural test. Division 01 requires substitution requests at least 10 days before bid opening; this request came 12 days after notice of award. The contractor's bid also used Brand B without an approved substitution, so the bid may be nonresponsive. The substantive test is closer: Brand B claims equal EER and lower cost, but the section says 'No substitutions will be accepted' for district standardization, a legitimate basis when 14 schools share filters and controls. The 'or equal' language in Division 01 does not override the specific no-substitution clause; the specific controls over the general. The schedule claim is real but does not create an entitlement. Approval would also give the contractor the benefit of a bid it did not price as required.
2. What should the design professional recommend to the district?
Read the worked answer
Recommend rejection in writing, with a copy to the facilities director, and direct the contractor to furnish Brand A. Immediately confirm Brand A's 10-week lead time in writing and require the contractor to place the order now; with a 14-week opening, the schedule is tight but not impossible if submittals and shop drawings are expedited. If Brand A truly cannot meet the opening, the district can negotiate a formal change order with a credit for the Brand B cost difference, not an administrative 'substitution approval.' That preserves the bid process and documents the owner's decision. The facilities director should not approve administratively because it undermines the procurement rules and sets a precedent for other bidders.
3. What documentation is needed if the request is rejected or later accepted?
Read the worked answer
Log the request date, the 12-day post-award timing, the cited specification sections, and the bid documents. Issue a written determination within the contract's response time. If rejected, state that the contractor must furnish the specified product and that no time extension is granted for the contractor's choice to bid an unapproved product. If the owner later accepts Brand B, issue a change order with a credit, require full submittals and warranties, and revise the district master specification for future projects. Keep the facilities director's schedule concern in the record but separate it from the entitlement analysis.
