Bro)lvn, County Administrator Approved as to form and legal sufficiency: Dylan T. Reingold, County Attorney EXHIBIT A Work Order Number 3, Indian River County Department of Utility Services South Oslo Rd Water Plant Floridan Well Deepening and Performance Improvement PROJECT UNDERSTANDING Indian River County Utilities (IRCU) owns and operates six (6) Floridan supply wells which are the raw water supply and source water for the South Oslo Rd water treatment facility. During drilling and construction of the new wells S-7 and replacement well S -4R, it was discovered that enhanced well performance and potential for improved water quality can be achieved through deepening of the existing wells. The specific capacity (gpm/ft) of well S -4R was improved 10 -fold over the existing and abandoned well S-4 by drilling the new well S -4R deeper by more than 120 ft. Therefore, it is recommended to consider deepening the existing wells while the contractor is.on-site and incorporate additional drilling into their rehabilitation scope while the contractor is still mobilized. Improved water quality and well performance result in lower operating costs since the pumping energy is less and the membrane feed -pressures are lower with better water quality. The project will consist of deepening the borehole of wells' S-2, S-3, S-5 and S-6: o Mobilization of a larger rig Removal & restoration of electrical gear ® Specific capacity pump testing Drilling a 15 -inch borehole ® Acidizing and developing well Restoration of site and wellhead The following scope consists of additional oversight during drilling, and coordination tothe existing work order with IRCU. The well contractor, All Webbs Enterprises, Inc. (AWE) is already onsite and mobilized: SCOPE OF FORK TASI< 1- PROJECT MANAGEMENT Consultant will review schedule prepared by the contractor, provide coordination with IRCU operations and subconsultant, JLA Geosciences, Inc., and provide oversight of the well deepening procedures and activities by AWE. KAWPB_Civil\044572039 - SCRO Well S-4 ReplacemenADeepeningURCU Floridan Well Deepening Scope - IRCU 6.11.18.doexPage 1 of4 Consultant will assist with the processing of the change order to deepen each of the existing wells, as well as provide supporting information and technical evaluation into the merits of deepening these wells. Consultant will respond to contractor questions, and provide written responses for IRC to process for the work prepared by KHA. Consult will review change order proposal from contractor and provide review summary and recommendation to IRCU. TASK 2 - UFA WELL DEEPENING & CONSTRUCTION PHASE SERVICES Consultant will prepare guidelines for the deepening of four (4) Floridan aquifer production wells located in the South -Oslo Road Wellfield, which is in addition to the existing rehabilitation scope to be performed by AWE. Consultant will provide scope coordination and answer questions by the existing contractor. Consultant will provide construction phase services including hydrogeological services, performance testing of each well, and preparation of a supporting well completion report for wells #.S-2, S-3, S-5, and S-6 Floridan Aquifer wells. Consultant will utilize subconsultant services of JLA Geosciences, Inc. for the Hydrogeologic Consulting Services (JLA). Consultant will provide hydrogeological support and observation services during Upper Floridan Aquifer well deepening, including pilot hole drilling and reaming, geophysical logging, completion interval drilling and associated testing, preliminary well development, acid treatment, pump development and testing, post rehabilitation development testing and specific capacity testing; and witness post- rehabilitation videos. Consultant will also provide well performance testing, including water level measurements, specific capacity analysis, and basic water quality testing (conductivity, chlorides, silt density indices -SDI's and sand testing). Consultant will provide up to 280 hours of on-site hydrogeological services (JLA) for well deepening. Consultant will review completion interval drilling and testing data and review acid treatment and testing plans. Consultant will review pump test results and provide recommendations for permanent pump setting depth and recommended in service pumping rate. It is assumed that the existing pumps will be re -installed in the existing wells. . Consultant will coordinate water quality testing, which includes additional water quality data for membrane projections. It is assumed no FDEP permit will be required. Consultant will provide additional wellsite review pre- and post- deepening and rehabilitation since contractor must remove the existing wellhead equipment to allow an alternate deepening rig on-site. KAWPB_Civil\044572039 - SCRO Well S-4 ReplacementMeepening\IRCU Floridan Well Deepening Scope - IRCU 6.11.18.docxPage 2 o174 Consultant will attend meetings and make onsite site visits for each of the four (4) existing wells to be deepened; provide coordination during construction, review of individual well geophysical and video logging,, review contractor's submittals including acid treatment plan, onsite hydrogeologic observation during critical elements of deepening, well logging. Consultant will prepare four (4) copies of a hydrogeologic technical memorandum for rehabilitation of each well summarizing the results of these modifications. KHA will prepare a well completion report for the deepened wells #2, 3, 5 and 6, including a summary of the lithologic logs, field logs, hydrologic and water quality data, and preparation of figures, data, lithogic logs, and appropriate attachments. It is anticipated that the additional construction phase that will be added will be up to 380 calendar days from notice to proceed with the deepening scope to final completion. The re -installation of the well pump, column piping, and electrical service for the deepened wells is assumed to be included under the drilling and rehabilitation phase. Consultant will attend up to four (4) onsite progress meetings to discuss progress, review construction related issues, and provide coordination where needed. It is assumed that NO FDEP permitting will be required since the size of the well casing, and capacity of the wellpump will not change. The Contractor will provide the SJRWMD well construction and well completion reports. TASK 3 - SUMMARY TECHNICAL REPORT Consultant will prepare a summary technical report for the deepening of four (4) Floridan aquifer production wells, and submit DRAFT versions to IRCU staff for review.
