This $1.6 billion design-build highway project comprised an addition of a 10-mile northbound HOV lane on the I-405 between the I-10 and US-101 freeways, 3 major bridge replacements, 27 on/off-ramp realignments, 13 bridge widenings, addition of 18 miles of retaining walls and soundwalls. It also entailed coordination with Caltrans, the City and County of Los Angeles, and numerous affected utility companies and telecommunication firms.
High-profile elements of the project, among other things, were the demolition of the Mulholland Drive Bridge on two separate occasions. Nicknamed "Carmageddon I and II," the I-405 was closed between the I-10 and US-101 interchanges on two separate weekends beginning on Friday evening and reopening Monday morning to demolish the bridge safely. The KKCS project controls manager and senior scheduler assigned to the project coordinated the schedule with the design-build contractor beforehand to ensure the demolition could be completed on time. The demolition during Phase I was completed ahead of schedule with the freeway reopening 17 hours ahead of schedule.
KKCS provided construction management, claims management, project controls, scheduling, cost estimating, inspection, third party coordination, document control, and other services as required throughout design and construction. KKCS is currently serving as the Deputy Project Manager assisting Metro in the claims settlement and project close-out.
