LTK-designed railcarStaying on schedule as plans change requires great project management skills. 

San Francisco’s 10-mile Warm Springs Extension project was a collaboration between LTK and three partners. LTK performed complex systems engineering on a Fast Track schedule, including design and communication systems. The systems engineering included more than 560 integrated design elements, all requiring coordination with civil/structural infrastructure and track design.

The project team included LTK veteran engineers from our Seattle, Portland, Denver, Ambler, PA, and Boston offices. To cover the logistics of three time zones, and the complexities of 10 miles of grade level track, aerial track structures, and deep trench track segments, LTK assembled a lead team of engineers on site in the Milpitas, CA, project office. The lead team represented the four major systems disciplines: traction electrification, automatic train control, communications systems, and system-wide lighting and general electrical design.

Despite numerous civil design changes that resulted in changes to the Systems Design Plan, LTK performed all work on schedule and without any increase in contract price. The lead team was able to keep the design work focused, and spotted hold points as civil engineering problems arose.
