SR520 Montlake Lid Design/Build

The SR520 Montlake project is a four-year reconstruction of the existing highway that adds a landscaped lid and reconfigures the Montlake Boulevard interchange for improved travel safety, traffic capacity and transit system integration. The project completes a regional, cross-lake bicycle/pedestrian path along the entire corridor, with connections to local trails on both sides of Lake Washington.
Ergosynch is leading the integration and commissioning activities. Systems include traffic signals, intelligent transportation systems (ITS), CCTV, lighting, fire detection and suppression for the Montlake underlid, irrigation, electrical, and mechanical systems – all integrated with the WSDOT regional traffic management center.

Federal Way Link Extension

This project extends light rail from Angle Lake Station in the city of SeaTac to the Federal Way Transit Center. The 7.8-mile extension with three stations and three garages.

Ergosynch is serving as the Communications Systems design lead and Integration Manager. Work includes communications systems and building management system design. Integration management coordinates interfaces between all civil and systems disciplines.

SR 525 Mukilteo Multimodal Terminal

The Mukilteo Multimodal Project provides for the design and construction of a new Mukilteo ferry terminal and multi-modal transit facility connecting commuters to train and bus transit. The facility includes passenger and maintenance buildings, a supervisor’s building, transit center and new toll booths. Ergosynch performed communication and control systems design and fire detection system design including plans, specifications and estimates. Communications systems include network infrastructure, public address, visual paging, CCTV monitoring, telephones, fare collection, marine radio systems and ferry vessel wi-fi. Control systems include thebuilding management systems, weather monitoring, and PLC control of the overhead passenger loading hydraulics.

Link Light Rail

Ergosynch staff have been involved with Link Light Rail from the beginning. For the initial Central Link alignment, we provided communications and control systems design. During construction we provided construction management services until rail opening day. We also provided major design work for the communications systems and building management systems for all Link extensions including University Link, North Link, East Link and South Link. One of our significant contributions was the retrofit of the downtown tunnel where our personnel have extensive and special expertise with tunnel control systems and fire/life safety systems. We helped Sound Transit achieve final occupancy from the Seattle FireDepartment. We repeated this for the Hill tunnel. We also wrote the control system user manual and provided system operational training to the Seattle Fire Department.

E360 East Link Light Rail Project

Erogsynch was tasked for the civil systems integration and BMS design for the 2 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.

LAMTA Gold Line

Ergosynch staff lead the SCADA design for the Los Angeles Gold Line extension light rail project. Our responsibilities included design of the communication network and interfaces to traction power, signaling, fire and emergency management system, mechanical and electrical systems. Our engineers also designed the access control and intrusion detection system.
