Approved product lists

Bridge Construction

See this year's list

Lists of products pre-qualified for use on Department of Transportation (WisDOT) projects are compiled and maintained by the department. These lists include pre-qualified products, approved suppliers and certified sources of specific materials that exhibit satisfactory compliance to a given specification. Pre-qualification testing, inspections, and evaluation; process control inspections with certification; process control inspection with random department verification testing and independent third party plant certifications are some of the major methods of pre-qualification.

In accordance with the State of Wisconsin Standard Specifications for Highway and Structure Construction, Section 106 Control of Materials:

The department maintains product acceptability lists and other lists of approved products and approved manufacturers or suppliers. The department includes products on these lists based on the results of prior testing and a satisfactory performance history on departmental projects. The department may retest or re-inspect products after delivery to the project site to verify that they conform to the contract.

The companies shown on the approved lists may provide their products to WisDOT projects according to the applicable specification and/or policy memorandum. Although approved for use, any of these materials are subject to inspection, test, certification of compliance or certified report of test to the appropriate specifications or material properties, or rejection at any time. These lists will be updated as needed.

Contact information for each of the product categories is listed on the pages for the respective material. Contact that person for information regarding pre-qualification for specific materials.

Each year includes all of the files for that selected year.
