About this file
This document comprises an Addendum No. 1 and supporting bid documents for a state and local contract opportunity issued by the Iowa Department of Agriculture and Land Stewardship, Division of Soil Conservation and Water Quality. The project involves the design and construction of two pumped nutrient reduction wetlands in Calhoun County, Iowa (Project 26-2, CAL883229BN & CAL883229BS). The scope of work includes selective clearing, excavation, grading, installation of solar-powered lift stations with dual and single pump configurations, force mains, tile drainage systems, inlet risers, water control structures, drawdown pipes, riprap placement, and seeding at two separate sites. The North site (CAL883229BN) encompasses approximately 31,200 cubic yards of earthwork and 16.6 acres of seeding, while the South site (CAL883229BS) involves approximately 10,300 cubic yards of earthwork and 1.0 acre of seeding. All construction work except seeding must be completed by December 31, 2026, with structure seeding required by May 15, 2027, and buffer seeding by June 30, 2027. Sealed bids must be submitted electronically through the Iowa Management of Procurement and Contracts System (IMPACS) by 3:00 PM on May 20, 2026, with bid opening occurring simultaneously. A pre-bid conference was conducted on April 24, 2026. Addendum No. 1, issued May 6, 2026, updates the proposal and schedule of prices form (Document CC) and revises the engineering plans dated April 28, 2026, adding single cantilever slide gates and chain link fence bid items for each lift station and noting drainage district designations.
The estimated construction cost ranges from $375,000 to $475,000 for the North site and $175,000 to $275,000 for the South site. Bidders must submit a proposal guarantee (bid bond) equal to 10 percent of the base bid amount and, upon award, furnish a Performance and Payment Bond equal to 100 percent of the contract price within fourteen days of the Notice-of-Award. Monthly progress payments will be processed at 97 percent of completed work value, subject to 3 percent retention. Liquidated damages are assessed at $175.00 per day for all work except seeding and $125.00 per day for seeding-related delays. Construction materials are exempt from Iowa sales and use tax, with the Division providing tax exemption certificates. The contract documents, sealed by Professional Engineers Daniel Jensen (License No. 25063) and Kevin Bruxvoort (License No. 19927), specify compliance with NRCS standards, NFPA 70, ASTM standards, ANSI standards, and UL certifications. The successful contractor must be registered with the Iowa Department of Inspections, Appeals & Licensing and must commence construction within 14 days of the preconstruction meeting. Electronic grading files are available from the engineer of record, Dan Jensen of Shive-Hattery (djensen@shive-hattery.com). No incumbent vendor or current contractor has been identified for this project.
