systems will be identical and similar in nature in order to standardize operations . The system will generally consist of lime slurry and CO2 storage tank(s), feed systems for both , make-up water for the CO2 feed system , and modifications to the existing clearwell to improve mixing of the CO2/Lime feed streams to the degasified blended permeate stream . Consultant will size the storage tanks for lime and CO2, size the lime feed pumps and CO2 feed system , and will select pumps for the lime feed system and make- up water ( if necessary ) for the CO2 feed system at both facilities . Consultant will evaluate the impacts on the CT calculations which were prepared for each water plant and update the calculations for each facility . Consultant will provide updated CT calculations for Owners use and if necessary , submittal to FDEP. Consultant will coordinate and attend up to two (2 ) site visits with IRCU plant operations staff to other lime feed and CO2 feed systems currently in operation or being installed at other water treatment facilities in South Florida. Consultant will design interior modifications to the clearwell which will be necessary for the enhancement mixing of lime and CO2 . It is assumed that each clearwell bay (2 — South Oslo Road plant, 4 — North Hobart plant) will house a mixing chamber and/or device . Consultant will evaluate procurement methods for purchase of Cal �Flo due to its proprietary status and evaluate options for purchase of CO2 from multiple vendors . Consultant will provide structural calculations and design of the lime slurry and liquid CO2 tank slabs in accordance with the new Florida Building Code adopted March 15 , 2012 . Consultant will design a make- up water supply for the CO2 feed system which may require more than 100 gpm of supply water, consisting of two options : finish water supply from the distribution system , or booster pumps which draw water from the clearwell . Consultant will prepare an operating philosophy for the operation , control , and monitoring of the feed systems . Operating logic will be included in the technical specifications used in bidding the project . Consultant will provide electrical engineering services to serve the proposed chemical feed and storage systems , PLC systems , and instrumentation and control system . The design will consist of power distribution , electrical load calculations, site lighting, conduit and wire design , and panel design . The electrical engineering scope will consist of coordination , meetings, field investigation, drawing production, schematics , panel schedules , technical specifications , and opinions of probable construction costs . The Consultant will submit an updated opinion of probable construction cost for the project, based on 90% submittal and after final documents are prepared . Task 2 . 2 — Prepare Drawings and Specifications The Consultant will prepare design drawings of the proposed improvements at both water plant sites , consisting of the following sheets : KAWPB Civil\044572022 - IRCU stabilization\Scope\Finish Water Stabilization Scope - IRCU, tlnal . doex Page 3 of 7
