The City of Edmonds sought to upgrade its aging Wastewater Treatment Plant SCADA system. Ergosync supported the City through an on-call contract to replace the system and develop control strategies and wiring diagrams to guide the upgrades. At project kickoff, Ergosync developed a control strategy and accurate wiring diagrams to guide the upgrades, prioritizing the schedule to enable PLC programming. Throughout the project, control strategy documents were regularly updated to track changes. Ergosync also utilized an innovative tool to auto-generate internal panel wiring diagrams, accelerating the process and reducing costs. The existing HMI hardware was retained, with revised graphic screens integrated for the new PLCs. Ergosync implemented standardized data logging and Historian configuration, aligning with industry best practices and clearly documenting all data sources.

Erogsync was tasked for the civil systems integration and BMS design for the two stations and parking structure. Throughout the design process our engineers coordinated with all other disciplines to ensure a seamless integration between Civil and Systems contracts. This coordination required extensive 3D modeling using Revit to ensure all design elements were constructible.

The City of Edmonds required a new high-efficiency blower for their secondary aeration process, needing it installed and operational within two weeks to qualify for a significant energy utility rebate. The new blower provides a 30% energy reduction, better aeration control, and quieter operation. Ergosync was brought in for turn-key design services, quickly producing detailed wiring diagrams, network reconfiguration drawings, installation instructions, and test procedures. They modified the existing PLC logic, process control loops, and helped the plant start the blower on schedule, securing the rebate. Ergosync also developed new graphic interfaces for remote control, alarming, data logging, and monitoring blower performance, and successfully established communication between the blower and the plant SCADA system, overcoming challenges with limited original manufacturer documentation.

The SR710 freeway in Pasadena has a 5 mile gap. To support the closing of this gap, LA Metro needed to expand the fire & life safety systems for twin bore tunnels. Ergosync managed the systems design team for the preliminary engineering and cost estimate for the freeway and light rail tunnel alternatives. Systems included fire detection, fixed fire suppression system, ventilation, electrical, communications systems and the control center. The team modeled and analyzed the design of the fixed fire suppression system to contain the maximum heat release rate. This included developing the tunnel fire response logic based on the positive alarm sequence method to avoid false activation of the suppression system. Ergosync’s team also designed the ergonomic arrangement of the operation and maintenance center control rooms based on IS0-11064 standards.

Ergosync managed the design and installation of the fire & life safety systems for the Eisenhower-Johnson Memorial Tunnel on I-70. The project included upgrading the fire detection, fire suppression, emergency ventilation and electrical systems.

East Link extends Link light rail approximately 14 miles from downtown Seattle to Bellevue via I-90 and Mercer Island. The alignment includes the I-90 tunnels, bridges and aerial sections. During preliminary engineers, Ergosync served as the lead designer for the corridor-wide communications systems, overseeing interdisciplinary coordination, project management, and the development of communications systems for the 30% design phase. Later, during construction, Ergosync oversaw the design of the track bridge monitoring system for the I-90 floating bridge. This system monitors the custom track bridges that allow the transit system rails to be attached to the I-90 floating bridge. Based on CCTV analytics, the system will send alarms to the existing Sound Transit central control if abnormal conditions occur. The multi-sensor data units located at the track bridge are aggregated and analyzed and integrated with the general control system.
