The approved product list pre-qualifies materials and serves as part of DTSD's Quality Verification activity per Title 23 CFR 637 and WisDOT Standard Specification Section 106.3.2.
Product Submittal (Product meets requirements for list published below)
WisDOT will only evaluate products that meet the standards and requirements for individual approved product lists. Applicable pre-qualification activities include physical and chemical testing, fabrication plant inspections, and evaluation of product design data. These activities, as well as administrative function of pre-qualification, vary among products according to specific provisions contained in the Standard Spec or in the contract documents. Further information about materials administration can be found in Chapter 8 of the WisDOT Construction and Materials Manual or attached to the prequalified product list.
Contact information for each of the product categories is listed on the pages for the respective materials and sources. Use that contact for information regarding pre-qualification for specific materials.
Products placed on an approved product list must immediately notify WisDOT if the product manufacturer has made a material change to the product, the product has become the subject of legal action in the United States or any state, or all product information was not disclosed to WisDOT at time of application.
WisDOT may remove a product from an approved product list if it is determined the product needs further review.
Product Submittal (Product does not fit into an existing published list)
WisDOT only evaluates products that do not meet an existing prequalified product list when project specific needs are identified through the proprietary product process. Approved proprietary products will be added to the Statewide Proprietary List below. WisDOT utilizes
AASHTO Product Evaluation & Audit Solutions and
Unique, Patented, Proprietary Products (UP3) for evaluation of products.
Project Level Material Acceptance
Pre-qualification or approval does not constitute acceptance of the work under the contract. All pre-qualified materials are subject to inspection and/or testing from time of delivery until acceptance. Certifications of compliance or certified reports of test indicating conformance to the contract requirements may be requested by project staff per contractual acceptance procedures, or at the discretion of the engineer. Non-conforming materials are subject to rejection or price adjustment.
