2023-08PC Addendum 1 021324.pdf

This is an addendum to Bid #2024-08PC issued by the County of Portage, Wisconsin, through its Purchasing Department for road materials contracts for the Highway Department in 2024. Addendum #1, dated February 13, 2024, provides clarifications and revisions to specifications for seal coat chip materials. The addendum corrects date references in sections 8.3 and 8.4 to reflect 2024 as the applicable year and specifies that material must be stockpiled prior to May 1, 2024. The bid addresses two categories of seal coat chips: Fractured 3/8 inch seal coat chips, with approximately 10,500 tons estimated for the 2024 chip seal program, and Fractured 1/4 inch Washed Seal Coat Chips, which may serve as a replacement option for the 3/8 inch material. Both materials must meet Wisconsin State Specifications 475.2 with specific exceptions outlined in the addendum.

The addendum establishes detailed sieve size and weight passing requirements for each material type. The 3/8 inch seal coat chips must meet specifications including 100 percent passing at 3/8 inch, 0-60 percent passing No. 4, 0-5 percent passing No. 16, and 0-1 percent passing No. 200. The 1/4 inch Washed Seal Coat Chips have distinct requirements with 100 percent passing at 1/4 inch, 0-100 percent passing No. 4, 0-40 percent passing No. 8, 0-10 percent passing No. 16, 0-5 percent passing No. 50, and 0-1 percent passing No. 200. These specifications ensure material quality and consistency for the county's chip seal program.
