Letter of Recommendation PREPARED BY:Lisa Bauman REVIEWED BY:Sara Kappos SKK I1H8 S-H Project No.: 4203290 May 9, 2025 Rudy Koester, Public Works Director City of Waukee 805 University Avenue Waukee, IA 50263 RE: Change Order #2 – Review and Recommendation to Approve University Avenue Area Improvements - Phase 1 Dear Mr. Koester: Please find attached Change Order #2 for the University Avenue Area Improvements - Phase 1 project. The change order includes the following items: • Temporary Traffic Control for Flaggers • Rock Check Dam • Tile Line Repair • Water Main Valve Box Repair and Backfill • Water Main Fittings – 8” 45° Bends Temporary traffic control signage is added for flaggers on 6th Street/Ute Avenue to facilitate a lane closure during paving of the 310th Street asphalt connection to 6th Street/Ute Avenue. Rock check dams are added to the project to be used for erosion and sediment control in channel/ditch locations. While attempting to shut down the existing 18" water main for connections to the newly-installed water main, an existing water valve was found to be inoperable. Excavation, repair, and backfill of the existing valve box is added so the existing valve could be operated to shut down the main and allow for completion of the connections during the scheduled outage window. During excavation for this repair, an existing drainage tile line was encountered and damaged, requiring repair. 8" 45-degree water main bends are added to accommodate the elevation difference between the new 18" water main and the existing 8" water main connection at the west side of the Waukee Public Works building. We have reviewed the change order items and unit prices, and both are in line with anticipated amounts. If City staff concurs with this change, we recommend the City of Waukee approve this change order in the amount of $7,847.85 to the construction contract for the University Avenue Area Improvements - Phase 1 with Elder Corporation of Des Moines, IA.
