BART GES: Project

BART CBTC

Construction Management

BART Communications Based Train Control System, Oakland, CA, 2020-Present. Tarjuna is a part of a team to provide Construction Oversight services during the implementation of Contract No. 49GH-110 for the Design-Build of a Communications Based Train Control (CBTC) System for BART's Train Control Modernization Program. The construction is expected to be complete by Year 2030. The project requires to oversee the administration of a design-build, system-type contract for transitioning from a legacy fixed block Automatic Train Control System to Communications Based Train Control System that utilizes a moving block technology in accordance with the California Public Contract Code, Federal Grant Conditions and Contract requirements.

Tarjuna's expertise are in the following areas:

Project Management
Project Implementation
Deployment and testing of CBTC equipment
Deployment and integration management with Design Services During Construction
Management of agency preparedness, training, and manual development
Cost Management
Safety Certification
Risk Management and Mitigation
Claims management and dispute resolution assistance

The scope of work for Tarjuna will be worked out with CPM Team once the contract is executed with BART. Potential areas where Tarjuna can contribute to this project are as follows:

1. BART Legacy and CBTC Train Control System Overview

a. Provide Integrated Computer System: The Integrated Computer System (ICS) provides standard legacy ATS (nonvital) functions and

provides the human-machine interface. The new CBTC ATS System will interface with BART's legacy ICS System for the legacy train

control area and will be ported over to the new CBTC ATS. When the deployment of a CBTC area is cut-in, BART will retire that ICS

legacy train control system for the CBTC area cut-in.

b. Wayside ATP/ATO Train Control Subsystems:

i. Initial System, comprising the original BART Systems inbound from Concord, Daly City, Richmond, and Fremont; originally

Westinghouse, with software having been upgraded by Harmon/GE for interlocks

ii. Second generation Westinghouse stations, including the CX/MX(KE) track through downtown Oakland
iii. Third generation Westinghouse stations, including the Daly City Train Yard and turnback tracks connecting Daly City Station to

the Daly City yard
iv. GRS (General Railway Signal, now Alstom) extension stations, including lines out to Dublin/Pleasanton, Pittsburg/Bay Point,

and Colma
v. SFO extension stations (AdTranz, now Bombardier train control)
vi. WSX (Alstom) and SVBX (Alstom)
vii. VT A Phase 2 - New Greenfield Extension from Berryessa to Santa Clara Station (CBTC)

c. Vehicle Legacy ATP/ATO Subsystems: The VATC interfaces with the AFTC's via antennas through which it receives the maximum ATP

speed transmitted by the Speed Encoding System/MUX. This VATC system will be removed from the D-Car Cab area and relocate

the CBTC Temporary cabinet outside the cab and place where the old VA TC was located once all wayside CBTC deployment is

completed.

d. Yard Train Control Systems: The Yard Train Control system is a block signaling system with automatic switch control. Each yard tower

has a display and control console which indicates signal status, open routes, and track circuit occupancies.

e. CBTC Territory

i. All mainline tracks including stations, terminal stations, tail tracks, and terminal zones
ii. All spurs and sidings, mainline storage, pocket tracks and MOW tracks.
iii. Yard transfer tracks (i.e. transition area from yard into mainline territory).
iv. Hayward Test Track and other test track areas shall be equipped with CBTC for testing purposes only.

2. Project Management

a. Project Management/ Technical Oversight: The project requires to oversee the Contractor's performance of project management

activities necessary to successfully deliver a high-quality CBTC System that meets all Contract requirements and that is delivered on

schedule.
b. Project Collaborative Agreement: Project Collaborative Work Plan shall include topics such as methods and processes for project

management, integration of work sites, development of the migration plan, development of the common risk register, CORL

development and review process, design reviews, engineering management, communications, decision making, and conflict

resolution.
c. General Construction Oversight Services: The project requires to oversee the DB Contractor's design, development, manufacturing,

factory tests, construction, installation, integration, site tests, commissioning, demonstrations, safety certification and District training

for the CBTC System. The team also oversee Contractor's project management, engineering management, RAM management,

quality control, safety escorts and watchpersons, operations and maintenance support and manuals, safety and security

management, and training services to support the design and build of the CBTC System per the requirements indicated in the

Technical Specifications.
d. System Integration Services: The project requires to oversee the Contractor's management, development, delivery, installation,

integration, testing and commissioning of the CBTC System and associated elements through the agreed migration phases and

finally as a whole system.
