PROJECT DESCRIPTION:

Awarded “Construction Project of the Year” by ASCE to S2 Engineering on this $177 million project, SANBAG, in cooperation with Caltrans, the City of San Bernardino, and the Federal Highway Administration improved 7.5 miles of I-215 through the City of San Bernardino. The project broke ground in late 209 with construction completed in early 2014. Reconstruction and Widening project was a unique and complex project with an innovative design. The project included 15 new bridges, including one temporary bridge, 20,8151f of cast-in-place concrete retaining walls with a combination of spread footings and footings on piles, 2,368 linear feet of mechanically stabilized embankment walls, 3,208 linear feet of sheetpile shoring to support an existing railroad, 80,250 cy of concrete pavement, 88,600 tons of AC pavement, a storm drain system with pipe sizes ranging from 8 in diameter to 96 in diameter, landscape and irrigation, and freeway and city street electrical systems. This section of highway represents a major corridor in Southern California that was used by 83,000 vehicles per day on average in 2003, and is projected to carry 135,000 vehicles per day by 2030. The project’s design increases traffic flow, eliminates fast-lane entrances and exits, widens freeway bridges, aids traffic merging by adding auxiliary lanes, improves air quality, reduces noise with sound walls, and enhances access to both east and west sides of the city.

S2 Engineering provided construction management & IQA services on the RE, SR, inspection, and office engineering. S2 reviewed & processed CCOs, claims, CPM schedule, monthly reports, and prepared & participated in DRB hearings.

Construction activity required extensive coordination with Burlington Northern Santa Fe Railroad (BNSF), which has approximately 100 trains using the tracks each day in this area – an average of one train every 15 minutes. Additional and continuous focused coordination was required with SCE, The Gas Company, SB Water Company, City of San Bernardino, City Chamber of Commerce, CHP, Caltrans TMC, Caltrans Safety, Caltrans District and Structures Designs, Caltrans METS, RWQCB, AQMD, FHWA, and consultant designers, among others.
