The overall system concept and the authorization to proceed <br /> with Phase I of the above work plan are requested under this Agenda Item . Subsequent Phases will be <br /> brought before the Board of County Commissioners for acceptance under separate agenda items as the <br /> scope of work and fee schedule for each has been fully developed and verified by the SCADA Team . <br /> At the present time the SCADA Team has completed its development of the Phase I Scope of Work _ <br /> Staff has obtained a price quote from ROCHA Controls Inc . in the amount of $ 18- 084 for their portion of <br /> Phase 1 . work ( See Attachment-A) . The County ' s Computer Services Department will be involved in any <br /> computer hardware and / or software upgrades as necessary to link the Utility plant sites to the Counrv ' s <br /> network system . ROCHA Controls has been used previously by the County for software and programming <br /> changes at both water plant sites . ROCHA have also provided initial support / design for the North County <br /> Reverse Osmosis plant re-pump site in 1993/ 1994 along with design and support for the new North Beach <br /> Re-pump Station in 1999/2000 . They have provided design and support for the South Countv Reverse <br /> Osmosis plant upgrade in 1992 and support work at the Grand Harbor Re-pump station. The staff of the <br /> Computer Services Department has reviewed the attached proposal for ROCHA Controls and provides <br /> their endorsement of the scope of work and associated fees . <br /> It is expected that the outline system upgrades will require a minimum of a year to complete . <br /> The proposed SCADA system improvements will reduce the current leased/dedicated telephone lines by <br /> converting to wireless (radio) telemetry communication type equipment thereby allowing the removal of <br /> leased based telephone lines . The deletion of select leased telephone lines will result in a net saving of <br /> approximately $4, 840 per year in operating expense . <br /> BUDGET / FINANCIAL HISTORY : <br /> The Department of Utilities has over the last 5 -years been planting for a countywide SCADA system <br /> to monitor and if necessary control vital infrastructure components such as the Reverse Osmosis Plants . <br /> Miscellaneous projects such as the North RO Plant Construction, South Regional Wastewater Treatment <br /> Facility and the North Beach RO Plant conversion to a Repump Station initially incorporated a part of the <br /> overall SCADA system plan . I If <br /> The construction of the North RO Plant was one of the first integral pieces in the start of a countywide <br /> SCADA system. However, the Board may recall that the contractor for the RO Plant construction was in <br /> excess of 250 days behind schedule and was levied monetary damages as a result of their performance . <br /> The same contractor had also been awarded the contract for the South Regional WWTF Expansion prior to <br /> their downturn in performance. Again, the contractor was behind schedule and was levied monetary <br /> damages as a result of their performance . <br /> On December 7, 1999 the Department of Utilities recommended to the Board of County <br /> Commissioners that SCADA system improvements be deleted from the South regional WWTF contract and <br /> that the funds be reserved for use in implementing SCADA system improvements . The December 7, 1999 <br /> Agenda further requested that Staff be authorized to negotiate with the local vendors, suppliers, and <br /> subcontractors affiliated with the project and who were able to perform the required work ( see attachment- <br /> C) . <br /> The Board of County Commissioners has finalized three major construction activities related to the <br /> proposed water production pumping system upgrade. Contained within all three major projects, were <br /> originally designed elements of instrumentation and control technology and can be illustrated as follows : <br /> January 9 , 2001 <br /> 49 <br /> BIt 1 8 9 <br /> 5 <br /> kSe0x ° R 11 <br /> `:Y3 .�.� , <br /> tF*;� - <br /> , �a ' ` 7ys <br /> e <br /> Y <br /> i�v ,r,. . . -� rr ' «1{... � t.; rn z. s .aT � '. t +. �c�' � , 9 1 �, �zs•. �' <br /> s , r <br /> rx„£ >bh i➢=�krisr:u's- 'ay^,;-. a <br /> E4K <br /> ✓' :z .cv ,. , !
