Heartland Lower Cedar 25-26 Batch and Build Project - Construction Plans Summary
This document comprises detailed construction plans prepared by I & S Group, Inc. for the Iowa Department of Agriculture & Land Stewardship's Division of Soil Conservation and Water Quality for the Heartland Lower Cedar 25-26 Batch and Build Project in Cedar and Muscatine County, Iowa. The project involves construction of three denitrifying bioreactors and seventeen saturated buffer structures across eight sites (Sites 22, 24, 25, 26, 28, 31, 32, and 34), incorporating water control structures, drainage tile systems, geotextile fabric, woodchips, perforated and non-perforated HDPE piping, and riprap. Specific work includes excavation, earthwork, topsoil management, tile installation, water control structure placement, anti-seep collar installation, animal guards, buffer seeding, and site restoration. The construction schedule is strict, with Site 32 requiring commencement on June 16, 2026, as it will be showcased as a conservation practice demonstration. A pre-bid conference is scheduled for April 23, 2026, at 10:00 AM CDT at Belle Plaine Community Library, though attendance is encouraged but not mandatory. Written questions must be submitted by 3:00 PM CDT on April 30, 2026, and sealed bids are due by 3:00 PM CDT on May 6, 2026, with public bid opening via teleconference at the same time.
The estimated project cost ranges from $210,000 to $240,000. Bidders must submit a bid bond equal to ten percent of the bid amount and, upon selection, provide a Performance/Payment Bond equal to one hundred percent of the contract price. All contractors must be registered with the Iowa Division of Labor and the Iowa Department of Inspections, Appeals, and Licensing, with non-Iowa corporations required to provide proof of authorization to do business in Iowa prior to contract execution. The construction plans reference compliance with the 2024 Natural Resources Conservation Service (NRCS) Conservation Practice 604 (Saturated Buffer) standards for Muscatine County projects and Conservation Practice 605 (Denitrifying Bioreactor) standards for Cedar County projects. Technical questions should be directed to Spencer Pech, P.E., at spencer.pech@isginc.com, with copies to Emalyn Polz at emalyn.polz@iowaagriculture.gov or (515) 322-9073. The procurement documents contain no identified set-asides or restrictions limiting responses to particular categories of organizations, nor do they identify incumbent vendors or current contractors.

NOTES
EARTHWORK:
1.) UTILITIES. CONTRACTOR MUST CALL IOWA ONE CALL (1-800-292-8989) AT LEAST 48 HOURS (EXCLUDING WEEKENDS AND HOLIDAYS) PRIOR TO EXCAVATION BEING STARTED. CONTRACTOR IS TO IMMEDIATELY NOTIFY OWNER OF APPARENT CONFLICTS OF EXISTING UTILITIES WITH THE WORK. THE CONTRACTOR IS RESPONSIBLE FOR PROTECTION OF ANY UTILITIES ENCOUNTERED ON THE JOB SITE.
2.) TOPSOIL. FOR ALL OPEN TRENCH AND STRUCTURE EXCAVATIONS, CONTRACTOR IS REQUIRED TO STRIP AND SEGREGATE THE TOP TWELVE (12) INCHES OF TOPSOIL FROM SUBSOIL BY PLACING TOPSOIL ON ONE SIDE OF THE TRENCH AND REMAINING SPOIL ON OPPOSITE SIDE. STOCK PILES ARE TO BE PLACED SO AS NOT TO BLOCK FLOWS IN DRAINAGE WAYS. USE TOPSOIL FOR THE TOP ONE (1) FOOT OF BACKFILL FOR TRENCHES AND STRUCTURES. CONTRACTOR IS REQUIRED TO DESCRIBE TO THE ENGINEER HOW TOPSOIL WILL BE MANAGED AT THE PRE-CONSTRUCTION
CONFERENCE.
3.) SPOILS. UNLESS OTHERWISE NOTED, EXCAVATED SPOILS NOT USED FOR BACKFILL SHALL BE SPREAD EVENLY IN CONSTRUCTION AREA AS TO
NOT IMPEDE DRAINAGE. ALL EFFORTS SHALL BE MADE TO KEEP TOPSOIL ON TOP.
4.) CROP PROTECTION. CONTRACTOR IS DIRECTED TO LIMIT DAMAGES TO CROPS IN THE ACCESS AND WORK AREAS AS CAN BE ACCOMPLISHED
WITHOUT MATERIALLY SLOWING THE WORK PROGRESS.

EARTHWORK:
1.) UTILITIES. CONTRACTOR MUST CALL IOWA ONE CALL (1-800-292-8989) AT LEAST 48 HOURS (EXCLUDING WEEKENDS AND HOLIDAYS) PRIOR TO EXCAVATION BEING STARTED. CONTRACTOR IS TO IMMEDIATELY NOTIFY OWNER OF APPARENT CONFLICTS OF EXISTING UTILITIES WITH THE WORK. THE CONTRACTOR IS
RESPONSIBLE FOR PROTECTION OF ANY UTILITIES ENCOUNTERED ON THE JOB SITE.
2.) TOPSOIL. FOR ALL OPEN TRENCH AND STRUCTURE EXCAVATIONS, CONTRACTOR IS REQUIRED TO STRIP AND SEGREGATE THE TOP TWELVE (12) INCHES OF TOPSOIL FROM SUBSOIL BY PLACING TOPSOIL ON ONE SIDE OF THE TRENCH AND REMAINING SPOIL ON OPPOSITE SIDE. STOCK PILES ARE TO BE PLACED SO AS NOT TO BLOCK FLOWS IN DRAINAGE WAYS. USE TOPSOIL FOR THE TOP ONE (1) FOOT OF BACKFILL FOR TRENCHES AND STRUCTURES. CONTRACTOR IS REQUIRED TO DESCRIBE TO THE ENGINEER HOW TOPSOIL WILL BE MANAGED AT THE PRE-CONSTRUCTION CONFERENCE.
3.) SPOILS. UNLESS OTHERWISE NOTED, EXCAVATED SPOILS NOT USED FOR BACKFILL SHALL BE SPREAD EVENLY IN CONSTRUCTION AREA AS TO NOT IMPEDE
DRAINAGE. ALL EFFORTS SHALL BE MADE TO KEEP TOPSOIL ON TOP.
4.) CROP PROTECTION. CONTRACTOR IS DIRECTED TO LIMIT DAMAGES TO CROPS IN THE ACCESS AND WORK AREAS AS CAN BE ACCOMPLISHED WITHOUT
MATERIALLY SLOWING THE WORK PROGRESS.
TILE INSTALLATION:
1.) WORK LIMITS.
