HomeMy WebLinkAboutItem #12 Construct 18" Raw Water Supply Lower Floridan Aquifer Well at South Water Treatment Plant AGENDA ITEM COVER SHEET Meeting Date: June 5, 2007 Item # 12 Contact Name: Contact Number: Charles K. Smith, P.E 407 -905-3100 ext. 4000 Reviewed By: Department Director: Charles K. City Manager: Robert Frank Subject: Construct 18" Raw Water Supply Lower Floridan Aquifer Well at South Water Treatment Plant Background Summary: The decommissioning of the Jamela Water Treatment Plant included the abandoning of its raw water supply well. The well's capacity was planned to be recaptured by constructing a new well at either the Forest Oaks or South Water Treatment Plant. Staff is recommending the new well be constructed at the South Water Treatment Plant due to the its greater future high-service pumping capacity. The well is proposed to be drilled to a depth of 1600 ft. and will have a withdrawal rate of 1200 gallons per minute. The City's geotechnical consultant, SMW GeoSciences, Inc, has recommended that the City employ Diversified Drilling, Inc. with the well construction; piggy backing from Diversified Drilling's contract with Collier County. The construction of the well does not include the motor or pump, nor the associated piping and electrical controls. The City's existing Consumptive Use Permit grants approval of a new well at the South Water Plant. The current application for Consumptive Use Permit has a request for a new well at Forest Oaks Water Plant. Issue: Should the City construct a new 18" raw water supply well at the South Water Plant to transfer capacity from the abandoned well at the decommissioned Jamela Water Plant; and award the well drilling to Diversified Drilling, Inc., utilizing Diversified Drilling's contract with Collier County? Recommendations Motion to authorize the City Manager to contract with Diversified Drilling, Inc. to drill a new well at the South Water Treatment Plant utilizing Diversified's unit price contract # 06-3887 with Collier County, in the amount of $499,950. Attachments: Copy of Collier County contract # 06-3887 with Diversified Drilling, proposal and cost to construct new well at the South Water Treatment Plant, and a copy of the letter of recommendation from SMW GeoSciences, Inc.. Financial Impact: The available funding for this well development was approved in the Fiscal Year 05/06 budget and carried forward to this year's budget in the amount of $600,000. With the well drilling costing $499,950, the remaining funds, $100,050, will be available for the install the pump and motor, plus any associated items. Type of Item: (please marl< with an ':X'?

' TO: Mr. Charles Smith. P.E. Utility Director City of Oeoee 1800AD. Mims Road Ocoee, FL 34761 April 12, 2007 SUBJECT: Recommendation on Water Well Contractor South WTP Well, City of Ocoee, Florida Dear Mr. Smith: SMW GeoSciences, Inc. recommends that the City Ocoee contract with Diversified Drilling, Inc. for the purposes of construction of a new 18-inch Lower Floridan aquifer well at the South Water Treatment Plant. Diversified Drilling, I nc. is under contract with Collier County to provide similar well construction services and they are willing to extend the same services, unit rates and fees negotiated Collier County to the City of Oeoee. For your consideration we have attached a scan of the executed Work Order and Contract Value with a breakdown of unit prices included with Collier County contract. According to Diversified Drilling, the actual contract is a one-year renewable contract with COlllerCountyfor Bid # 06-3887. Diversified Drilling has prepared a cost estimate for the City of Oeoee's proposed well using the same Schedule of Values {SOY} as in the Collier County CQntract. Please note that a reduction on the schedule of values has been made on line item A06 where an 15.inch steel at $401ft is substituted In lieu of the Collier County 16-inch Fiberglass Reinforced plastic casing at $63/ft. In addition, as the City of Ocoee will only be constructing one well, versus the four wells in the Collier County contract, Diversifled has also applied a 75% reduction on main contract items such as mobilization, demobilization and performance bonds. We trust that the attached information is sufficient for your use at this time. If you have any questions please contact the undersigned. Sincerely, SMW GeoSciences, Inc. Sarah M.
