The CSI 1 5C is the Substitution Request During the Bidding Process form, developed by the Construction Specifications Institute to standardize how contractors and vendors propose product alternatives on construction projects. The form must be submitted during the bidding period, before the bid closing date specified in the project documents.
General contractors, subcontractors, and material suppliers submit this form when they want to propose a product different from what the project specifications require. Architects and project managers review the requests and issue a formal approval or denial before contract award. Any party to the construction bidding process that needs to request a product substitution must complete this page-long form.
The substitution request must include the specified product details, the proposed substitute manufacturer and model number, technical data demonstrating equivalency, and a written explanation of why the substitution is being requested. Complete and accurate submissions speed up the review process and improve approval chances. The form type is standardized across CSI member organizations to ensure consistency in how substitution requests are evaluated.
