Since 1986, Wong has been performing project management, design, construction management, inspection, testing, and startup on numerous systems, civil and structural projects for SANDAG (formerly MTDB) in San Diego.

Wong's staff designed the systems for the initial 16-mile South Line and provided construction management, testing, and startup services. The initial South Line was built in record 30-months, from preliminary engineering to opening of revenue service. This was the first modern LRT system to be implemented in the United States and proved that cost effectiveness and efficiency in timely implementation was possible. It has since been used as a model for the implementation of Light Rail Transit throughout the United States.

Due to the high success of the system, SANDAG has specifically requested Wong to provide design and construction management services for multiple large-scale projects to which were all completed on-schedule and within budget. The total construction cost for these projects is $500 millions.

Wong has proven that the firm is an invaluable partner to SANDAG in design, construction management and system startup. Wong's participation in key San Diego projects is summarized as follows:

General Construction Management Services
San Diego Association of Governments (SANDAG) desires to develop and construct public transportation improvements, some of which could be within the right-of-way of other local agencies. These other local agencies include the California Department of Transportation (Caltrans), Metropolitan Transit System (MTS), North San Diego County Transit Development Board (NCTD), and all other local cities, counties, and government agencies which make up SANDAG's Board for regional decision-making. SANDAG needs flexibility to management, develop, and/or assist other agencies in the development of high quality transportation related improvements.

SANDAG selected Wong as a Prime Consultant to perform General Construction Management Services on these transportation related projects for a contract maximum amount of $10 million. The construction management services include construction contract quality assurance and safety compliance, field inspection, transit inspection, field office engineering and administration, project scheduling, contract dispute assistance, materials sampling and testing, material/product inspection, constructability review, geotechnical investigations, storm water monitoring and research, surveying and construction staking, and other support services on as as-needed basis to support the development and construction of various transportation and transit projects.

Mission Valley West Extension Project
Wong was responsible for the preliminary systems engineering and final design for the 6.3-mile extension. The work included systems implementation for bridges and for at-grade and elevated stations. Wong also played an instrumental role in the inspection, testing, and sytems startup of the Mission Valley West Extension. The firm was specifically contracted to bring their rail transit expertise of construction, testing, and systems startup to help SANDAG achieve a successful and timely completion for Superbowl XXXII.

East Line, Bayside, Santee, and Old Town Extension Projects
Wong was responsible for the construction management of the systemwide elements of four major extensions of the San Diego Rail Transit System which included the East Line, Bayside, Santee, and Old Town LRT Extensions - over 24-miles. The Santee and Old Town Extensions involved extensive coordination with freight railroads and Amtrack which operate in the same right-of-way as the LRT system. In the course of this assignment, Wong was involved in numerous field design enhancement to reflect the actual field conditions.

Rail Yard Expansion Project
Wong was responsible for the design and construction management of the expansion of the existing rail yard, as well as several new maintenance/shop facilities. The design and specifications for this project were developed to avoid disruption to existing yard operations.

Testing and Startup/Rail Activation
Wong has participated in major roles in the successful startup of every light rail extension in San Diego. Wong developed test plans, procedures, and test reports in the testing and startup, including the monitoring of the tests and performing full investigations into any problems uncovered through the course of the testing.

LRT and Railroad Signaling
Wong was responsible for the design and construction management of the double-tracking on the SR-94 and the La Mesa Curve Straightening Projects. Wong has provided design and construction management for railroad signaling on numerous SANDAG projects involving joint use track and/or shared right-of-way.
