Los Angeles, 2012 - 2015

DC Engineering Group completed work on the I-405 Sepulveda Pass Widening Design-Build Project which added a 10-mile HOV lane and improved supporting infrastructure such as ramps, bridges, and sound walls. The segment of the I-405 between the I-10 and U.S. 101 freeways was widened.    As a sub-consultant, we provided professional   engineering   services   including   traffic   engineering support for impacts caused to all local city and county streets as a result of the widening of I-405. DC Engineering Group also prepared Transportation Management Plans which included data collection and SYNCHRO analysis to facilitate stage construction work associated with Caltrans facilities and Local facilities.   DC Engineering   also supported   HNTB   with   Local   Agency Coordination  with  Caltrans,  LABOE,  LADOT,  LABSL,  LADWP,  LABSS,  Los  Angeles  County,  and  other various agencies through the design review and approval process.
