CP&Y provided electrical <br />engineering design services for the 69th Street Wastewater Treatment <br />Plant. The first project was an emergency work order to replace most <br />of the plant's medium voltage distribution infrastructure. The second <br />project was for the replacement of existing Eddy Current clutches with <br />Variable Frequency Drives (VFDs) for the digested sludge pumps at <br />the thickener facility. The third work order was the replacement of 40 <br />low -voltage motor control centers at the lift stations within the reactor <br />complex and at the sludge pump station. The work order also included <br />replacement of the VFDs associated with the return activated sludge <br />pumps at each one of the associated pump stations. <br />Walnut Creek WWTP Water Reuse Initiative Tank Assessment <br />& Repairs, City of Austin, TX.* Electrical/Instrumentation QA/QC. <br />Project included tank inlet mixing improvements, addition of high <br />service pump, and evaluation and recommendation of new flow <br />meter. A bulk water filling station was also included in the project. <br />Addition of a UV Disinfection System at Village Creek WWTP, <br />City of Fort Worth, TX.* Electrical/Instrumentation Design Engineer. <br />The project for the UV disinfection system associated with the new <br />Reuse Pump Station included new variable frequency drives, 480V <br />distribution panelboards, modifications to existing MCC, lighting, <br />instrumentation and control design to connect the new UV system into <br />the existing DCS. Responsible for reviewing the project submittals and <br />answering contractors RFIs during the construction phase. <br />2016 Water Reclamation Facility Rehabilitation, City of <br />Cedar Park, TX.* Electrical Design Engineer. The project included <br />design services for rehabilitating the aeration system and providing <br />miscellaneous facility repairs and safety improvement items throughout <br />the plant. Aeration system options were developed for increased oxygen <br />transfer as well as an evaluation of energy consumption and power <br />requirements for the proposed alternatives. Evaluation criteria included <br />air requirements, treatment efficiency, reliability, operational complexity, <br />maintenance requirements, constructability/ease of access and 20-year <br />life cycle cost. It was recommended that a diffused aeration system <br />be installed in the existing aeration basin. Project challenges included <br />installation of the diffuser grids without taking the basin out of service <br />and a fast -tracked schedule for both design and construction activities. <br />Basin Pump Station Improvements, San Antonio Water System, <br />TX.* Electrical OA/QC. The project consisted of a pump station and <br />miscellaneous chemical system upgrades associated with an 80-MGD <br />high service pump station facility. The improvements included the <br />replacement of all major electrical equipment, pump improvements, <br />planning upgrades for the chlorine and fluoride facilities, and adding <br />an emergency dry scrubber system. Other project improvements <br />included structural and architectural improvements, wells design for <br />TCEQ compliance, high service pump motor actuated valve replacement, <br />switchgear replacements, and yard piping replacement. <br />Central WWTP HVAC System Upgrades, Trinity River Authority, <br />Dallas, TX.* Electrical/Instrumentation Design Engineer. The <br />project consisted of the addition of a new chiller plant building and <br />modification of the HVAC system at five of the existing buildings atTRA <br />Central WWTP. Project included 15 kV pad mounted switchgear, pad <br />mounted transformers, generator termination cabinets, low voltage <br />motor control centers, panelboards, transformers and instrumentation <br />and control design for the new chiller plant and the new outdoor air <br />handling unit building. Responsible for review of contractor's submittals <br />and RFIs. <br />Mountain CreekWWTP Plant and Collection System <br />Improvements, Trinity River Authority, Midlothian, TX.* <br />Electrical Design Engineer. Responsible designer for the addition of <br />filter cells, clarifiers, sodium hypochlorite system and modification of <br />the HVAC system atTRA Mountain Creek WWTP. Oversaw the design of <br />modification to the electrical system for the addition of generators at <br />the influent lift stations. Project included modifications to existing MCCS, <br />addition of 480V distribution panelboards and transformers, site lighting <br />and generators. Responsible for utility coordination and preliminary <br />power system studies. Responsible for reviewing the project submittals <br />and answering contractors RFIs during the construction phase. <br />East Side WTP Improvements to the Transfer Pump Stations No. <br />1 and 2, Dallas Water Utilities, Sunnyvale, TX.* Lead Electrical <br />Design Engineer. Designed the new electrical system that included 5 kV <br />metal clad switchgear, 5 kV motor control centers, variable frequency <br />drives, pad mounted transformers, low voltage motor control centers, <br />panel boards and transformers. Developed the one -line diagrams, <br />electrical site plans, power and control plans, lighting and receptacle <br />plans, interconnection diagrams and duct bank schedules for transfer <br />pump stations No.1 and 2. Coordinated with instrumentation designers <br />to capture their requirements as part of the electrical design. Delegated <br />tasks to designers and drafters. Coordinated with subconsultants to <br />ensure all of the disciplines designs were concurrent with the electrical <br />design. In charge of project schedules for the electrical portion of the <br />project and ensuring project deliverables were dispatched on time. <br />Responsible for reviewing the electrical submittals and answered <br />contractor's RFIs during construction. <br />*Work performed prior to joining Ardurro <br />ARDURR A B-34 City of Santa Ana Water Resources Division <br />RFP 22-002 1 May 24, 2022 <br />
