215 Widening – South, Murrieta, California (2012)

In December 2010, the Riverside County Transportation Commission (RCTC) awarded a $15 million construction contract for the widening of six miles of Interstate 215 between Murrieta Hot Springs Road and Scott Road.  Road widening activities started in April 2011 and the Project is now 100% complete. As prime consultant, Southstar, led by Mr. Amr Abuelhassan, MS, PE, QSD, successfully led the construction management Team to deliver this important project.  This is the southernmost portion of a 29.25-mile stretch of freeway that RCTC— along with its project partners—plans to widen to reduce traffic congestion and delays, conserve gasoline, improve air quality and enhance the movement of goods through the region.  The project added one lane in each direction to create three northbound lanes and three southbound lanes to this section of freeway. Widening occurred on the freeway median, which minimized the project’s impact on the community and motorists during construction. In addition, the project widened the Keller Road Undercrossing, adding a median barrier, repairing existing pavement and adjusting grading and drainage.  Prior to bid solicitation, Southstar reviewed the Design Plans for this project and suggested modifications to the staging plans that reduced the construction duration by four months.  During the life of this project, approximately 110,000 tons of hot mix asphalt (HMA) was placed under the new Caltrans Section 39 Specifications for asphalt concrete.  Under this contract, Southstar provided the Resident Engineer, Structure Representative, Assistant Resident Engineer and Office Engineer as well as Inspection services.  The total capital project cost is estimated at $31 million.  This project was completed on time and under budget with zero claims.
