REHABILITATION SOUTH COUNTY WATER TREATX%ENT PLANT Background The South County Water Treatment Plant is approximately 18 years old. Raw water is supplied by six wells constructed into the Floridan Aquifer. The depth of the wells reportedly ranges between 600 and 700 feet below ground surface. Wells 1 through 3 were the initial wells constructed with the original plant. Wells 4 through h were installed at a later expansion to the facility. Potential problems with the wells were identified by the County through the implementation of previous Work Authorization No. 13. Obstructions in the boreholes were identified in well nos. 1, 2, 3, and 5 that are potentially impiictin,g the performance of these wells. Based on the conditions of these wells, it has been determined that entering each of the wells and reaming out the borehole is the best means of,removing these obstructions. Services Task 1.0 Well Construction Related Contract L]ncumenls Preparation The Engineer will prepare contract documents for the reaming of each well under this subtask. Specifications will be prepared for ramming of the wells which will include requirements for: a construction sequence ■ qualikications r experience ■ equipment e drilling/reaming F+ casing protection ri cement r well development ■ rcporting and records r drilling fluids r disposal of drill cuttings and site cletuiup Task 2.0 Contract Administration The Engineer will conduct under this subtask administrative tasks associated with the construction management of this project. These activities include the prernnstrtiction meeting, biweekly progress meetings with the County and the contractor to discuss construction issues related to the project, generate monthly project summary reports, review appli,,:atiuns for 63399.d. 1-3-1 pity muitt, and coordination of the work. Permitting issues regarding reaming activities with the St. Johns River Water Management District are also included. Task 3.0 Monitor Contractor Progress lite Engineer will provide a qualified Resident Project Representative (RPR) to observe the contractor's progress and to determine, in general, if lite contractors executed work is being done in accordance with the contract documents. in addition, the RPR will be on-site to describe the lithology encountered, observe reaming operations, and monitor development activities. It is anticipated that the RPR will be onsite 70 percent of the time when well construction activities are occurring. In the event the contractor is late in completing; thu required work, the Engineer may require additional compensation for additional time -dependent services which may be required. CDM anticipates that it will take a contractor Gil days to substantially complete this project. Task 4.0 Flowmeter Evaluation The Engineer will evaluate proposed replacement flowmeters for Well Nos, 1, 2, and 3 at the South County Water Treatment Plant. Included in this task is assessing the condition of the existing meters, flowmeter alternatives and options, and evaluating perfeirmance characteristics of the proposed flowmeters. _ Task 5.0 rump Bearing [Wplacement Services associated with the previous workauthoriration included inspection of well pump bearings. The pumps at Well Nos. 7 through 4 are no longer manufactured and rephicement parts are not available. The well rehabilitation contractor had to have the replacement bearings specially made. Replacement costs total approximately $32,000. Contingency Services in the previous work authorization accounted for $25,040 of the cast. Tile remainder is included in the outside professional crisis. Contingency Services The pump and column of Well No -4 were idontified as being; slack during fieldwork associated With a previous work authorization. It is unknown how much effort will be requirutl to remove the pump and column at Well No. 4. he condition of the well is also unknown, so it is indeterminate if Well No. 4 requires reaming. The County has directed the Engineer to make an attempt to remove the pump and column at Well No. 4. To cover the potential costs of pump and column ren°roval and the reaming of Well No. 4, a Contingency Services allowance is provided for in thie, proposal. Activities designated under this allowance of 20% of the total amount will be performed only after receiving formal approval by Utilities Department personnel. Well No. 4 or the pump may become damaged as a consequence of the removal of tine pump and column. if this occurs, repair to the well and/or the pump could exceed the contingency funds that have been set aside.
