About this file
This is a proposal and schedule of prices worksheet for the Memmelaar West AML (Acid Mine Drainage) Reclamation Project, an acid mine drainage reclamation construction project managed by the Iowa Department of Agriculture under RFB IA-362. The project encompasses site mobilization, clearing and site preparation, offsite waste disposal, impoundment discharge management, and erosion control measures across two sites in Mahaska County. The scope includes excavation of 87,400 cubic yards with 12,000 cubic yards of muck removal, installation of approximately 2,155 linear feet of dual-wall pipe in sizes ranging from 6 inches to 18 inches, subgrade preparation treating 530 tons of agricultural lime, and seeding operations across 15.9 acres. The worksheet details 42 line items with estimated quantities for both north and south sites, including materials such as filter sock, wood fiber, tied concrete block mat, rip rap, Hickenbottom risers, PVC outlets, and various seed mixes for upland pasture and wetland fringe applications. Bids were due August 11, 2026 at 2:00 p.m. CDT, with the RFB opening on July 28, 2026 at 4:00 p.m. CDT. No contract term, renewal options, or anticipated award date is specified in this document.
The worksheet requires bidders to enter unit prices and calculate total costs for each line item in the IMPACS system, with specific instructions that fractional quantities must be entered as lump sum amounts rather than decimal values. Bidders must respond to all specified line items on the provided proposal and pricing worksheets and submit a bid bond as outlined in the RFB documents. Bidders must satisfy all bid specifications to be deemed responsible and complete multiple certifications including certification of bid accuracy, independence of bid development, debarment status, and Iowa sales and use tax compliance. The contract includes commodity codes in the 02100-02700 range covering site preparation, drainage, erosion control, and seeding activities. No total contract value is specified in this pricing worksheet, and no information regarding funding sources, set-asides, or incumbents is provided.

“IMPACS does not recognize fractional or decimal quantities less than one (1). Unit prices for fractional quantities shall be entered as one (1) lump sum as the bid price to perform the required work. For example, a work item may require a unit price equal to $1000/acre, but if work item involves only three-tenths (0.3) of one acre, then the lump sum bid entered on IMPACS would be $300 for that work item.”
