Discussion and Consideration of Change Order #9 – Boomerang Corp - North Park Road Improvement Project – Motion to Approve

AGENDA ITEM # K-6 AGENDA INFORMATION TIFFIN CITY COUNCIL COMMUNICATION DATE: August 29, 2025 AGENDA ITEM: Discussion and Consideration of Change Order #9 – Boomerang Corp – North Park Road Improvements Project ACTION: Motion Approval Scope of Change This change order adds three new bid items to ensure compliance with NPDES permit requirements for stormwater intake protection: 1. Grate Intake Sediment Filter Bag (EC-604) – 5 units at $192.50 each 2. Maintenance of Grate Intake Sediment Filter Bag – 5 units at $5.50 each 3. Removal of Grate Intake Sediment Filter Bag – 5 units at $5.50 each These items are necessary for protecting grated intakes (I-07, I-09, I-11, I-12, I-13) not covered by existing open throat sediment filter bid items. Cost Justification All unit prices were reviewed and found to be reasonable based on recent bid tab analyses: • Grate Intake Bags: $192.50/unit is above the average ($148.38) but well below the max ($450.00), including a 10% contractor markup. • Maintenance and Removal: $5.50/unit is significantly below average and maximum bid prices. Recommendation Staff recommends approval of Change Order #9 in the amount of $1,017.50 to Boomerang Corp. for the addition of stormwater intake protection items required for NPDES compliance. The change is minor, federally eligible, and necessary for environmental permit adherence. ATTACHMENTS: Change Order #9 1
