BARTLogo Bay Area Rapid Transit System (BART) San Francisco Bay Area

The Bay Area Rapid Transit District (BART) is a rapid transit rail system which provides service to passengers in San Francisco, Contra Costa, San Mateo, and Alameda Counties. The system includes 48 passenger stations and approximately 109 miles of double track. HSQ Technology has worked extensively with BART on its expansion projects. This included designing and installing Station Communications and a SCADA system to support both the existing BART system, as well as the new BART facilities.

eBART Contra Costa County Transfer Station (November 2015 - May 2018)

The project called for design and implementation of a communication system for the new rail passenger service comprising approximately 10 miles of new track between the existing Pittsburg/Bay Point BART Station and the City of Antioch. The eBART Project will use independently propelled railcars known as Diesel Multiple Units (DMUs), that will operate on standard gauge rail and transfer to BART traditional light rail trains. This project was a fixed bid project that consisted of the integration of the network infrastructure for communications back to BART Central for the various subsystems consisting of Mobile Radio BDA System, SCADA, CCTV Security, Emergency and PBX Telephones, Train Monitoring System, Public Address System, Variable Messaging and Displays, Access Control, and local monitoring.

University Link and South Link Extensions (June 2012 - December 2016)

This project involved adding three new stations to the existing Seattle Sound Transit light rail system as well as updating several communications subsystems. The installation, configuration, and commissioning of the entire communications package, which included Access Control, Closed Circuit Television, Public Address / Variable Message System, Tunnel Radio System,and Telephone.

Angle Lake Station (April 2014 - September 2016)

The management design and implementation for the new south link station extension at Angle Lake. This is a design build project for 1.6 mile light rail segment that will run south from SeaTac Airport on an elevated guideway along 28th Avenue to South 200th Street. HSQ project scope includes the integration for the network infrastructure for communicating back to Sound Transits Operation and Maintenance Facility (OMF) for the various sub-systems consisting of CCTV Security, Emergency and PBX Telephones, Public Address System, Train Monitoring System Variable Messaging and Displays, Access Control, and local station monitoring.

East Link Light Rail E130 Project (November 2017 - June 2018)

This project consisted of design and implementation for the East Link Mount Baker and Mercer Tunnel Projects. The scope of work included the integration of the of the network infrastructure for communicating back to the Sound Transit Operation and Maintenance Facility for the various subsystems consisting of Access Control, Emergency Telephones, and a Radio BDA System. Fourteen miles long, East Link includes ten stations from Seattle's International District to Judkins Park, across I-90 to Mercer Island and South Bellevue, and through downtown Bellevue and the Bel Red area to Redmond Technology Station.

Conventions Place Center Project (July 2018 - May 2019)

HSQ was responsible for the management, design, and implementation of the Convention Place Station Bus Service Decommissioning Project for the discontinued bus service monitoring and scheduling. The HSQ project scope included the integration for the systems for communicating back to the Sound Transit Operation and Maintenance Facility for the various subsystems consisting of Emergency Telephones, Access Control, Tunnel Radio BDA System, Station Control Unit (SCU), Field Control System (FCS) I/O EVS, BMS control modifications, and SCADA / HMI modifications and controls.

Tunnel Control, Traffic Control, and SCADA Equipment (May 2010 - December 2014)

This project included providing tunnel and traffic operation equipment (including CCTV equipment and traffic control cabinets with PGRS communication), fiber optic cable, distribution, communication equipment, SCADA equipment (Wonderware HMI and GE PLCs), and a carbon monoxide monitoring system. It also included installation, startup, field testing, system integration testing,and training associated with the equipment provided by HSQ.

The tunnel SCADA system monitors circuit breaker statuses, ventilation fan statuses (vibration, on/off, fail), fire control statuses, and CO levels and controls ventilation fans and lights. The SCADA Submaster is a WonderWare InTouch node which communicates with the SCADA System at the Caldecott Tunnel Operations Center. Redundant GE RX3i PLCs communicate over a RS-485 network with 13 GE Durus controllers located throughout the Tunnel. A third GE RX3i PLC located at the SCADA Submaster provides an interface for I/O local to the Submaster. All three RX3i PLCs communicate with the SCADA Submaster over Ethernet. An additional GE RX3i PLC is provided for lighting control. There are approximately 450 I/O points in this SCADA System.
