Dmytryka Jacobs Engineers, Inc.

(DJE) specializes in the design, development, and implementation of instrumentation and control systems for water and wastewater facilities. A significant history of past experience has been developed. Here we identify several projects of what might be similar in nature to this effort with which DJE has been involved.

All of the projects identified as complete were under budget and within the time schedule required. Specific to these projects is DJE’s experience with PLCs, MMI software, and modes of communication.

Toledo, Ohio Water Treatment Plant

DJE replaced the existing Bristol SCADA system for the City of Toledo’s water treatment facilities and distribution system. DJE was awarded the contract to perform the upgrade as a design/build method of delivery late in 2014; the final contract amount was over $5,000,000. A second, parallel contract just over $1,000,000 was awarded to DJE to provide radio telemetry from the remote sites to the water plant. This new control system is Allen Bradley Logix based, with Allen Bradley FactoryTalk HMI software.

DJE’s scope of services included all network design and configuration, development of all PLC and HMI software, configuration and installation of all servers, all panel design/construction and installation, and configuration and installation of all microwave and VHF radio based telemetry. The emphasis and planning revolved around the plant's need to continuously produce water with the least amount of disruption. Implementation of the new PLC programming almost imediately produced improved operation of the high service pumps and more efficient filter operation. The final effort included more than 1000 engineering drawings, over 70 PLC panels, workstations and servers at three different locations connected via a fiber and microwave backbone, and approximately 25 remote telemetry locations connected via microwave, VHF, UHF, and cellular radio.

Northeast Ohio Regional Sewer District – Automated Program Management

The Northeast Ohio Regional Sewer District (NEORSD) is in the process of upgrading the PLC systems at both the Easterly and Southerly WWTPs and for the collections system throughout the District’s service area. In short, all three projects consist of PLC lifecycle upgrades and I/O expansion, network switch upgrades, DeviceNet conversions, UPS upgrades, and instrumentation additions. A team consisting of a local electrical contractor and DJE was the low bidder for all three projects and was awarded the projects. DJE is providing all of the panel designs and assembly, instrumentation supply, and field start-up once installed by the electrical contractor.

Cleveland Water Department; Morgan Pretreatment and Residuals

DJE was the controls system integrator for Project No. 414 at the Cleveland, Ohio Morgan Water Treatment Plant. DJE was a subcontractor for this work with tasks including the design and construction of the PLC control panels, VFD pump control panels, factory testing panels, verifying communication network, specifying, purchasing, and field commissioning of primary devices. DJE’s subcontract was for almost $2,000,000 and a sub-bond was provided by DJE to the general contractor for this amount.

Cleveland Water Department; Fairmount Pump Station Rehab

DJE provided the controls system integration for the Cleveland Fairmount Pump Station Rehab Project No. 412 as a subcontractor. The project was performed for the rehabilitation of the Cleveland Baldwin water plant finished water pumps. Tasks included the design and construction of new PLC pump control panels with manual hardwired controls, factory testing panels, verifying communication network, specifying, purchasing, and field commissioning of primary devices. DJE’s subcontract was for approximately $1,200,000 and a sub-bond was provided by DJE to the general contractor for this amount.

Columbus, Ohio Hap Cremean WTP

DJE was the Systems Integrator during the construction of the Columbus, Ohio HAP Cremean Water Plant Treatment Improvements project. The subcontract amount was in excess of $3,100,000. DJE was responsible for the design and construction of the Allen Bradley ControlLogix PLC control panels, the factory testing of approximately 75 control panels built by DJE for this project, the verification of communication networks to verify the proper transmission of data, and the selection, purchase and commissioning/start-up of field instrumentation for this project.

Granville, OH WTP Control System Upgrade

DJE was hired as a Design/Build contractor at the Granville, OH water treatment plant and was tasked with replacing an antiquated control system that was failing regularly. DJE hired subcontractors for the electical and equipment installation. The control valves and magnetic flow meters in the filter gallery were specified/selected/purchased by DJE, mounted and wired by our subcontractors, and then tested and comissioned by DJE. New computers were supplied with Wonderware InTouch HMI and TopView Alarm dialing software. Allen-Bradley CompactLogix was used within the plant for high service and filter control. A PanelView touchscreen operator interface was supplied and programmed for plant control while on the plant floor. A new 153 MHz Elpro licensed radio telemetry system was provided and installed at 4 remote sites.
