Exh 8BAGENDA ITEM #SB AUGUST 27, 2001 CITY OF ATLANTIC BEACH CITY COMMISSION MEETING STAFF REPORT AGENDA ITEM: Professional Engineering Services -Assessment of the Buccaneer Floridan Aquifer Production Wells SUBMITTED BY: Donna Kaluzniak, Utility Director DATE: August 3, 2001 BACKGROUND: The City is in the process of renewing the potable water Consumptive Use Permit for the Atlantic Beach and Buccaneer districts through the St. Johns River Water. Management District (SJRWMD). During apre-application. meeting, the SJRWMD noted that the City would be required to perform geophysical and video logging of our eight wells as part of the permitting process. This process includes pulling the well pumps, inspecting and televising the wells, and measuring various parameters to determine the integrity of the well casings and sanitary seals, checking for voids in the open hole section of the wells, and determining their overall condition. In addition, one of the wells at Water Plant #3 (902 Assisi Lane) has been steadfly losing production capability. Performing the logging and inspection activities noted above would allow us to determine the exact cause of the problem, and make needed repairs before reaching a critical stage. Camp, Dresser & McKee (CDM) is assisting the City in the permitting process and staffrequested a proposal to perform the above work and provide an analysis and recommendations based on their findings for the four wells in the Buccaneer District. Wells in the Atlantic Beach District will be logged and inspected during the lower demand period in the fall. CDM has submitted a proposal to perform the above work in the amount of $39,597. They will use W. Earl Floyd & Son, the contractor who has performed the majority of our well installation and repair work, to pull the wells and conduct the video and geophysical logging. CDM will provide a professional geologist to be on-site during this work, to observe and review the findings and make recommendations for well repairs, rehabilitation or replacement. CDM will provide drawings for any modifications recommended or made during the project. The expected time to complete this work is 2 - 3 days per well. If the findings show that immediate repairs or modifications are needed, staff would like to perform this work immediately, while the wells are already off-line and the pumps pulled, if possible. For this work, the City would contract directly with W. Earl Floyd & Son, at a rate of $85.00 per hour, plus materials. In order to determine if the actual cost of the logging and hourly repair rates were reasonable, staff requested quotes on these items from two other well contractors. W. Eazl Floyd & Son's logging rates were mid-range, and their hourly repair rates were less than half of the other well AGENDA ITEM #SB AUGUST 27, 2001 drillers' costs. Because staff has been very pleased with the quality of work and expertise provided by W. Earl Floyd & Son, and expects there will be some repair work required, we recommend using this firm, as proposed by Camp, Dresser & McKee. BUDGET: A total of $100,000 is available in the Water Utility Fund, under account number 400-4101-533-6300. This amount was originally budgeted for the Church Road Water Main, for which we received CDBG funds. RECOMMENDATION: Award the' contract for Assessment of the Buccaneer Floridan Aquifer Production Wells to Camp, Dresser & McKee in the amount of $39,597, and authorize. the City Manager to sign the contract. Authorize staff to proceed with necessary repairs, with a follow up report on the activities and costs as soon as they are available. ATTACHMENTS: 1. Proposal from Camp, Dresser 8c McKee. REVIEWED BY CITY MANAGER: ~s_ AGENDA ITEM #8B AUGUST 27, 2001 This is EXHIBIT A, consisting of _ pages, referred to in and part of the Agreement between OWNER and ENGINEER for Professional Services dated , 2001.

ENGINEER shall provide Basic and Additional Services as set forth below. PART 1 -BASIC SERVICES CDM Project No.: Title of Project: Assessment and Maintenance of the Buccaneer Floridan Aquifer Production Wells 1.0 DESCRIPTION OF TASK ORDER The work effort to be completed by CDM for Task Order No. 2000- consists of the resident oversight of contractors involved in removing the pumps from four Floridan aquifer production wells located at the Buccaneer Water Treatment Plant. The pumps will be inspected for build up of minerals (calcification) and general maintenance, repair and evaluation. Following the removal of the pump from the well, the well will be logged with video and geophysics to evaluate the condition of the well. 2.0 SCOPE OF SERVICES TASK 1 Project Planni ~ and Scope Development CDM will develop a scope of services for the evaluation of the Buccaneer Floridan aquifer production wells. CDM will work with the City of Atlantic Beach and their contracted Well Driller on scope, costs and scheduling. TASK 2 Review Existing Data This task consists of reviewing data on existing Buccaneer Floridan aquifer production wells including location, casing diameter, depth of casing(s), total depth of the well, date of installation, yield, size of existing pump, and water quality data. K:~andieW,iw135.tlx AGENDA ITEM #8B AUGUST 27, 2001 TASK 3 Resident Project Representation For this task CDM will place professional geologist in the field while the pumps aze pulled from the wells. The geologist will work with the well driller in determining the need for maintenance or repair of the pumps. The geologist will also review the findings of the geophysical and video logging in determining the condition of the well and the possible need for well rehabilitation, as needed. It is estimated that it will take two to three days to complete this work for each well. CDM will subcontract with the city's well driller for all downhole services including pulling the pumps, geophysical logging, and video logging of the wells. Any maintenance or repairs to be performed by the well driller will be approved by the City prior to completing the work. Any costs for pump or well repairs/rehabilitation will be billed directly to the city at the well drillers hourly rate. After completion of the field work, CDM will send a letter to the city describing the work performed along with a summary of the conditions of the wells. This,letter can then be sent to the SJRWMD in support ofthe CUP application. 2.0 ASSISTANCE OR DATA TO BE PROVIDED BY THE CITY The city will provide to CDM the results of any recent well maintenance records or well logging performed on the wells in BuccaneerService Area.
