1) The BART Concord Station
The BART Concord Station is part of Earthquake Safety Program, the Program includes construction of structural modifications to portion of the existing system to provide adequate resistance to forces of a major seismic event. The result will reduce the risk to and improve the safety of patrons and personnel during an earthquake. The Work in this contract includes construction of structural and related sitework, architectural and mechanical/electrical modification to improve the seismic safety of Concord Station. Concord Station is an operating BART station and the Work shall not interrupt Revenue Operations. (Cost 5.5 Million).
ABA provided construction management for this project.

2) The BART Pleasant Hill Station
The BART Pleasant Hill Station is part of Modernization Program, the Program includes construction of structural modifications to portion of the existing system. Pleasant Hill, now with a sub-name of Contra Costa Center and the station receiving new inverse black text on white signs is an elevated BART station with two side platforms for the two track Pittsburg/Bay Point Line and opened on May 21, 1973.
These two side platforms have concrete walls with brown framing for individual canopies only in the middle of the platforms. From here fare control is directly beneath the platforms. Just west of the platform along Sunne Lane is a modern 3,111 space 7 level parking garage that charges $1 for parking and opened on June 30, 2008. This parking garage replaced surface lots to allow the building of the Contra Costa Center Transit Oriented Development around the rest of the station. This development is slowly coming together but plenty of original BART parking lots still sit fenced off an abandoned around the station. The development has also modernized the station, in addition to the new signage, the lights in the lampposts towards the ends of the platforms are new with LED lights. Outside the station BART logos dot the sides of the station and the concrete just looks cleaner. Clocks now dot the sides of the elevator shafts.

4) San Bruno Grade Separation Project
This public works project consists of constructing a grade separated rail alignment from I-380 in South San Francisco to San Felipe Avenue in San Bruno. Major elements of work include addition of new control point CP Scott, shifting of main line tracks from South Linden Ave to Scott Street, construction of a two track shoofly, track raise on an MSE embankment, three grade separated street crossings involving lowering current street grade, three pedestrian under crossings, relocation of San Bruno Station onto an elevated structure, temporary station, pump station, vehicular traffic signals, train signals and communication system. The work is more fully described in the Contract Documents.

5) Regional Connector Transit Corridor Project
The Central Station is located on the south side of 1st Street, diagonally between Central Avenue and Alameda Street and will be constructed using conventional cut-and-cover construction methods. The station alignment and box location were established to meet the requirements of the tunnel portal locations on 1st Street and Alameda Street, as well as providing connection to the existing north bound and east bound Gold Line tracks. The provision of a “Wye” intersection to the north and east bound tracks also influenced the location of the station box. The depth of excavation will be approximately 45 to 50 feet below the existing ground surface.
