Wong has been providing engineering services for design and construction management projects as a Prime Consultant to the Sacramento Regional Transit District for over 18 years. Wong's exceptional management skills, close attention to detail, and stringent QA/QC procedures were critical elements which led to the success of many Sacramento Regional Transit District's Projects. These projects totaled over $180 Millions and are summarized as follows:

Sacramento Sunrise/Gold River Extension
The systems design, performed in two segments, included traction power substations, power distribution system, train control with automatic block signaling and highway grade crossing warning systems, and traffic signaling. Systems integration and coordination between civil/trackwork and systems construction contracts were critical elements of the work. Wong was responsible for the overall systems integration for the extension project including integration with civil contracts prepared by a separate civil consultant. The first phase of the project, the Mather Field Extension, included tie-ins to the existing system, modifications of existing single track segments to add a second track, and upgrading substations.

Sacramento Mather Field Extension Project
As prime consultant on the Mather Field Extension Project, Wong provided Design, Construction Management, Integrated Systems Testing, and Startup services. This extension project included a half-mile double tracking to the Starter Line and an additional 2.3-mile segment extension from Butterfield Road to Mather Field Road. Careful consideration of tie-ins to the existing system was taken into account, enabling the construction to be completed with minimal impact on Regional Transit's daily operations. The entire alignment was built adjacent to active Union Pacific tracks, which required nearly daily coordination with the railroad. Wong also managed the testing and systems startup, bringing the system into operation within schedule and budget.

Systems Design Criteria
Prior to implementation of the major extension projects, Sacramento Regional Transit retained Wong to enhance the systems design criteria for traction power, train control and wayside signaling, and communications.

South Sacramento Corridor Project
As prime consultant to Sacramento Regional Transit, Wong performed constructability reviews for the bid documents of the South Sacramento Corridor Project. The objective was to minimize change orders and avoid claims. The independent constructability reviews were conducted for construction of the civil/trackwork, wayside signaling, systems integration, and stations. The utilization of Wong's construction management database software led to effective and timely reviews.

Double Tracking Project
Wong designed the systems including traction power distribution and signaling systems for the double-tracking between 59th Street and Stockton Boulevard. In addition, Wong was prime consultant providing construction management services for three double tracking projects.
