TRANCAS CREEK BRIDGE PROJECT– MALIBU, CA

Summit Environmental Contractors is completing work for the Caltrans District 7 Trancas Creek Bridge Project. This includes removing and disposing of 230,000 gallons of contaminated liquid, air monitoring, engineering support, and site management.

The existing 96-year-old, 85-foot wide, 90-foot-long concrete bridge, which was constructed in 1927 to span Trancas Creek on Pacific Coast Highway in Malibu, is being replaced with a new concrete bridge which will be 105 feet wide by 240 feet long.

Summit’s dewatering services are required in order to start the project. The stream and lagoon area will be restored to the original condition or improved through additional restoration efforts. Once completed, the lagoon area will be reopened to the public. Environmental commitments and BMPs before, during, and post construction will ensure water quality and natural resources are protected throughout the entire process.

Carmenita Road Interchange – Los Angeles, CA

 

Summit Environmental Contractors (SEC) was awarded a contract by Security Paving Company for the California Department of Transportation in District 7 Los Angeles County, CA. The purpose of this project is to widen Interstate 5 by adding one High Occupancy Vehicle (HOV) lane and two mixed-flow lanes in each direction.

Summit’s scope of work included:

  • Safety and Project Plan Preparation
  • Air Monitoring and Project Oversight
  • Removal and Transportation of Hazardous Material
  • Engineering Support and Field Testing

Summit played a vital role in removing and properly disposing of 60,000 tons of contaminated soil while also SEC providing dewatering services for over 400,000 gallons of contaminated liquids out of the project site. In order for the project to start and be completed on time these services are required. Contaminated liquids not only create health hazards for project site personnel, they also can damage equipment on site if neglected.  Summit’s services are necessary to create a safe and non hazardous work environment for all personnel involved, as well as the surrounding community by removing these toxins.

Valley View Ave Interchange – La Mirada, CA

 

 

Summit Environmental Contractors was awarded the Valley View Interchange Project for the California Department of Transportation (Caltrans) in District 7 . The project consisted of the widening of both the Valley View overcrossing and the I-5 freeway.

Summit’s scope of services included the completion of the following plans: 

  • Site-Specific Health and Safety Plan 
  • Sampling and Analysis Plan 
  • Excavation Plan & Transportation Plan
  • Stockpile Management Plan

The field services Summit provided included the sampling and analytical testing for 1,200 stockpiles and 6,000 samples, soil characterization, transportation and disposal for more than 42,000 tons of contaminated material. In addition, Summit performed dewatering, sampling and disposal for more than 400,000 gallons of contaminated liquid. Maintaining the project site is crucial for completing jobs on time and on budget. If water overflows and causes an unsafe work environment, not only can the project be pushed back, but also it increases the chances of personnel onsite getting injured or exposed to unsafe liquids.
