This is a Product Substitution Request Form related to Collin County, Texas's Construction project for CCSO Subsurface Water Intrusion (Contract 2026-404). The project involves selective demolition and restoration at an inset entrance to address subsurface water intrusion issues, including removal and replacement of brick masonry, topping slab, sidewalk, and associated components. Work includes installation of new sheet waterproofing, protection course, flashing, sealants, and weatherproofing elements integrated with the existing building enclosure, followed by repair and reinstallation of masonry, topping slab, and storefront systems as required. Final site restoration encompasses backfilling, sidewalk replacement, and grading to provide positive drainage away from the building. The project consists of both waterproofing and structural modifications, with the structural phase requiring engineer assessment of field conditions to determine exact repair requirements.

The opinion of probable construction cost for this contract is $200,000.00. The form itself is a mechanism for contractors to request substitutions of products specified in the contract documents, allowing for proposed alternatives to be evaluated and approved prior to bid submission or during contract execution. This substitution process ensures that any product changes maintain compliance with project specifications and performance requirements while accommodating material availability or contractor preferences.
