About this file
This is a Schedule of Prices worksheet for Bid No. 26-2 issued by the Iowa Department of Agriculture & Land Stewardship, Division of Soil Conservation and Water Quality, for the construction of two nutrient reduction wetland projects in Calhoun County, Iowa. The procurement encompasses two concurrent contracts: Cal883229BN-North and Cal883229BS-South, each located in Section 29, Township 88 North, Range 32 West. The North project involves 29 line items including site stripping and preparation, excavation (6,176 cubic yards), earthfill operations (14,335 cubic yards), topsoil placement (4,535 cubic yards), drain tile removal (2,270 linear feet), water control structures, piping systems, riprap placement (150 tons), and seeding of 16.6 acres. The South project consists of 29 similar line items with smaller quantities, including excavation (1,056 cubic yards), earthfill operations (8,008 cubic yards), topsoil placement (1,220 cubic yards), drain tile removal (65 linear feet), and seeding of 1.0 acre. Sealed bids are due by 3:00 PM CDT on May 20, 2026, with public bid opening the same day via IMPACS and Microsoft Teams. A non-mandatory pre-bid conference is scheduled for April 24, 2026 at 10:00 AM at the Calhoun County Conservation Board in Rockwell City, Iowa. Construction must commence within 14 days of the preconstruction meeting, with completion required by December 31, 2026, structure seeding by May 15, 2027, and buffer seeding by June 30, 2027.
Bidders must submit unit prices and total costs for each line item on this worksheet for both projects, with the combined total base bid required for both contracts. The document specifies that bids will only be accepted through the online Iowa Management of Procurement & Contracts System (IMPACS); this worksheet is for planning purposes only. Bidders are required to register with IMPACS prior to submission and must be registered with the Iowa Department of Inspections, Appeals & Licensing. A bid bond equal to ten percent of the bid amount and a Performance/Payment Bond equal to one hundred percent of the contract price are required of the successful contractor. The estimated total construction cost range is $375,000 to $475,000 for the North project and $175,000 to $275,000 for the South project, with a combined potential award value between $550,000 and $750,000. Non-Iowa corporations must provide proof of authorization from the Secretary of State to do business in Iowa prior to contract execution. Written questions regarding plans and specifications must be submitted to Project Engineer Dan Jensen at Shive-Hattery by 3:00 PM on May 5, 2026 to be included in a final addendum.
