About this file
This is a Proposal and Schedule of Prices document prepared by the Iowa Department of Agriculture and Land Stewardship, Division of Soil Conservation and Water Quality for Bid No. 25-12, which encompasses two nutrient reduction wetland projects in Calhoun County, Iowa. The solicitation requests construction services for two distinct projects: Cal883301A located in Section 01, Township 88 North, Range 33 West, and Cal883220A located in Section 20, Township 88 North, Range 32 West. Cal883301A requires extensive earthwork including approximately 5,600 cubic yards of excavation and fill, drainage tile investigation and removal totaling 770 linear feet, roadway surface removal of 158 square yards, installation of various pipe structures and culverts, riprap revetment placement of 399 tons, and seeding of approximately 12.4 acres, with a specified completion date of September 1, 2026 for all work except seeding (September 15, 2026). Cal883220A involves approximately 1,775 cubic yards of general excavation and earthfill, installation of modified water control structures and lift station components, placement of 2,200 square feet of tied concrete block mat, 218 tons of riprap revetment, and seeding of 1.3 acres, with a completion date of June 15, 2026 for all work except seeding (June 30, 2026). Bids must be submitted electronically through the Iowa Management of Procurement and Contracts System (IMPACS) by 3:00 PM on October 8, 2025, with bid opening occurring at 3:10 PM the same day.
The proposal requires submission of a bid guarantee equal to 10% of the base bid amount and mandates execution of a Performance Bond in an amount not less than 100% of the contract award within fourteen days of receiving Notice-of-Award. Liquidated damages are established at $175 per day for all work except seeding and $125 per day for seeding activities, to be withheld from contractor payments upon written notice. The document includes a notarized affidavit requirement wherein the bidder must affirm examination of all contract documents, accurate preparation of the proposal, and compliance with competitive bidding regulations free from collusion or fraud. The schedule of prices for Cal883301A includes 33 line items covering site preparation, excavation, fill placement, structure installation, and seeding, while Cal883220A includes 18 line items addressing similar construction activities at a smaller scale. Bidders are required to submit unit prices and extended totals for each line item, with a final grand total for both sites combined. The document serves as a worksheet for bid preparation, with actual bids accepted only through the IMPACS online system.
