Title
Consider a resolution authorizing the Mayor to execute Supplemental Contract No. 1 with Carollo Engineers, Inc. for the Hesters Crossing and CR 172 Water System Improvements (GR-07) Project.
Body
The City’s 2023 Water Masterplan Update identified Project GR-07 near Hesters Crossing and County Road 172 where water pressures are low due to local topography. Additionally, as development continues in that area, water pressure during peak usage is anticipated to decrease.
The master plan concept for GR-07 was to shift the area into a higher pressure plane. The Basis of Design Report (BODR) identified a less-invasive alternative that meets the intent: a supplemental interconnection from the 1031 pressure plane to support the existing 971 pressure plane under higher-demand conditions.
This item is for the approval of Supplemental Agreement No. 1 with Carollo Engineers, Inc., for detailed design and construction phase engineering support to implement the BODR recommendation. The project includes approximately 2,700 LF of ductile iron waterline and a Pressure Reducing Valve. The connections will generally be located at CR 172/Hesters Crossing Road and north of West Louis Henna Boulevard near Frontera Drive. The not-to-exceed Supplement Contract No. 1 amount is $266,300.00, bringing the total contract value to $365,237.00.
Cost: $266,300.00
