Gilman Bridge Underground and Duct bank 

I-5 Bridge SRK worked on.jpg

Owner: University of California 

Client: MCTC

Year Completed: 2018

Estimated contact value: $400,000


Work Completed: 

Install electrical and telecommunication lines in Medical Center Drive and the new Gilman Bridge that spans over Interstate 5.  Challenges included excavation and installation around numerous existing utilities, and coordination with the bridge construction crews to install conduit and duct banks in the bridge.


We have many highly experienced underground installation crews that have been involved in numerous challenging pipeline projects in Southern California. 

SRK went above and beyond by performing the construction on the UCSD Health property maintaining a clean, safe and secure construction site in a highly visible and busy street area. Provided excellent communication and coordination with the other contractors and trades constructing the bridge.

Mid-Coast Corridor Transit Project

The Mid-Coast Corridor Transit Project will extend the Trolley Blue Line service from the Santa Fe Depot in Downtown San Diego north to the University City community, serving major activity centers such as Old Town, the University of California, San Diego (UCSD), and Westfield UTC. 

The proposed project would be funded in partnership by SANDAG and the Federal Transit Administration (FTA).

The Trolley extension route – known as the Locally Preferred Alternative (LPA) – was approved by the SANDAG Board in July 2010. It begins just north of the Old Town Transit Center and travels in existing railroad right-of-way and alongside Interstate 5 to serve UCSD and University City. The extension will serve nine new stations: Tecolote Road, Clairemont Drive, Balboa Avenue, Nobel Drive, VA Medical Center, Pepper Canyon (serving UCSD west campus), Voigt Drive (serving UCSD east campus), Executive Drive, and the terminus station at the Westfield UTC transit center.

Project type: 5 retaining walls  

Work completed:

5 counterfort retaining walls totaling over 1.4 miles in length and 90,000 square feet. Walls were up to 2700’ long and 23’ high, support 4 rail road tracks designed for E-80 loading.  Three walls were built within the Rose Creek Channel with extreme flood and scour potential.  The unique precast panel retention system eliminated shoring and saved SANDAG and the contractor several million dollars with value engineering. The wall design was thoroughly reviewed by over 40 engineers, including engineers for SANDAG, NCTD, and the City of San Diego.

This light rail extension will improve the quality of life and mobility for San Diego residents and visitors, offering an alternative to increasingly congested freeways and a reliable connection to employment, education opportunities, health care, retail centers and attractions.

With our experience on both the owner’s side and the contractor’s side of projects we understand how to meet everyones needs fairly to keep a project moving. We can manage contracts, submittals, claims, or entire projects. Our time managing projects for large civil construction companies has taught us a lot.

Walls were constructed much faster than the originally planned walls, allowing the project schedule to stay on track. One wall was built in 48 hours. Walls were designed and built by SRK Engineering.
