About this file

Written by GovTribe AI · Aug 2, 2024

This document contains plans for the construction of a nutrient reduction wetland in Grundy County, Iowa. The project involves selective clearing, excavation, grading, steel sheet pile weir construction, tile installation, a CMP water control structure, and seeding. Key project details include approximately 14,500 cubic yards of earthwork, 1,770 square feet of sheet pile, 2,100 linear feet of tile installation, 970 tons of riprap, 140 cubic yards of grout, and 18 acres of seeding. The estimated construction cost range for this project is $390,000 to $440,000. Bidders must follow the instructions in the Notice to Bidders to be included on the plan holders list, which is required to receive meeting minutes, addenda, and an updated plan holders list.
