Title
Joint committee action approving Change Orders Number One, Two, Three, Four, and Five for the Highland Lake Water System Project (Phase-2 New Water Supply Well Drilling and Testing) with Municipal Well and Pump resulting in a cost increase from $520,059 to $691,292.
Staff Summary
• Using awarded ARPA funds, on November 25, 2024, a contract was issued to Municipal Well and Pump to drill and test a new well on Lakeside Drive that will serve the Highland Lake Water System.
• Existing well log data provided a high level of confidence that sufficient water production would be found in the limestone formation aquifer, within 300 feet of the surface; sufficient production was not found within 300 feet of the surface, and the most prudent course of action is to drill additional well depth to the sandstone aquifer.
• Change Orders #1, 2, 3, 4 and 5 direct the contractor to continue well drilling, install casing pipe, compensate the contractor for unexpected downtime, modify the path of pumped test water, as well as descope unnecessary project elements, which resulted in a net increased cost of $171,233 (contract $520,059 to the final contract $691,292).
• The original contract received ARPA funds, and the contract was executed by the County Administrator; the additional funds ($171,233) necessary will be provided by the Department of Public Works enterprise funds and an emergency appropriation is requested.
• In accordance with Section 33.082 of the Lake County Purchasing Ordinance, when the total of change orders, contract modifications, or price adjustments on any contract approved by resolution by the County Board exceeds 10 percent of the original contract amount, approval of the standing committee in charge of the contracting department or agency and the Financial and Administrative Committee is required.
• This joint committee action authorizes and directs the Purchasing Agent to execute contract change orders one through five with Municipal Well and Pump increasing the original contract value from $520,059 to $691,292.

RE: Committee action approving Change Orders One through Five to the agreement with Municipal Well and Pump
Using awarded ARPA funds, on November 25, 2024, a contract was issued to Municipal Well and Pump to drill and test a new well on Lakeside Drive that will serve the Highland Lake Water System. Existing well log data provided a high level of confidence that sufficient water production would be found in the limestone formation aquifer, within 300 feet of the surface; sufficient production was not found within 300 feet of the surface, and the most prudent course of action is to drill additional well depth to the sandstone aquifer.
1. Change Order #1 directs the contractor to drill the well deeper into the sandstone formation until a better water production was estimated, resulting in an increased cost of $84,972.
2. Change Order #2 directs the contractor to install a 6” casing pipe through the limestone formation up to the sandstone layer, resulting in an increased cost of $193,532. Installing the 6” casing pipe is required for the well in accordance with IEPA requirements.
3. Change Order #3 is to compensate the contractor’s downtime caused by the decision-making process for drilling deeper described in Change Order #1, resulting in an increased cost of $46,290.
4. Change Order #4 is to remove scope from the original contract and the Owner’s Directed Allowance, resulting in a decreased cost of $165,341.
5. Change Order #5 directs the contractor to modify the path of pumped test water, resulting in an increased cost of $11,780.
6. Change orders #1, 2, 3, 4, and 5 result in a net increased cost of $171,233 from the original contract $520,059 to the final contract $691,292.
7. The original contract received ARPA funds, and the contract was executed by the County Administrator. The additional funds necessary will be provided by Department of Public Works enterprise funds.
8. In accordance with Section 33.082 of the Lake County Purchasing Ordinance, when the total of change orders, contract modifications, or price adjustments on any contract approved by resolution by the County Board exceeds 10 percent of the original contract amount, approval of the standing committee in charge of the contracting department or agency and the Financial and Administrative Committee is required.
9. This joint committee action authorizes and directs the Purchasing Agent to execute contract change orders #1 thru #5 with Municipal Well and Pump increasing the original contract value by $171,233 from $520,059 to $691,292.
