Over the past twenty-five years Evans Brothers Inc. has completed over 1,000 projects of varying size and difficulty. As the demolition industry evolved and environmental concerns were brought to the forefront, EBI repositioned itself to better serve it's clients' demolition and hazardous waste remediation needs. The following select projects exemplify Evans Brothers Inc.'s ability to find feasible solutions that meet the differing needs of clients and environment:
DECONSTRUCTION OF LETTERMAN HOSPITAL
San Francisco, CA The Presidio Trust
Demolition of former Letterman Hospital Complex, consisting of a 10-story hospital structure and a 4-story laboratory/research facility. Over 1,000,000 square feet of building space included. Asbestos, lead, & hazmat abatement included in scope of work. Concrete & asphalt generated from project recycled and turned into 3/4" aggregate base on-site for use in future development.
MOSCONE CENTER EXPANSION PROJECT
San Francisco, CA City and County of San Francisco Public Works
Demolition of a six story concrete structure at the corner of Fourth Street and Howard, Downtown San Francisco. The top two floors of this structure were built using structural steel; the remaining floors consisting of poured-in-place concrete. The building had a glass facade that looked out over Fourth St. During the demolition process it was discovered that the building was constructed substandard concrete and the engineering demolition plan had to be altered during the project to ensure public safety. Instead of felling all six stories of the structure, the top two floors had to be dismantled by hand and the structural steel was hoisted from the building with live traffic moving below. The project was completed without a safety incident.
DEMOLITION OF SB I-680 TEMPORARY VIADUCT AT I-680/24 INTERCHANGE
Walnut Creek, CA C.C. Myers
Demolition of eleven freeway overpasses including a 2,100 of two-lane bridge. The 90-foot high structure spanned the newly designed interchange that had three bridges facilitating traffic below. Bridge demolition was performed at night. 24 steel girders in lengths of 140', weighing 22 tons each, were carefully unbolted and removed unharmed from the five south spans to be used in the Olympic blvd. off-ramp.
DEMOLITION OF FORMER ELEMENTIS PIGMENTS PLANT
Emeryville, CA City of Emeryville Redevelopment Agency
Hazardous soils, heavy metals, corrosive, asbestos, hazardous liquids, storm water management, water treatment, ecology, and archeology. This former paint pigment plant was built in the early 1900's on top of a Native American Shellmound in Emeryville, CA. With Temescal Creek running through the project and feeding the San Francisco bay within a quarter mile this project, the heavy February rains were managed and rainwater was collected over the 5-acre site and processed without any storm water contamination. Nine buildings and two large tank farms with over 100 tanks were cleared from the site and all of the structural steel, tanks, and piping was salvaged for recycle.
FURNISHING AND OPERATING A CONCRETE RUBBLE CRUSHING PLANT
Harbor Transportation Center-Oakland, CA Port Of Oakland
Provide crushing service to furnish the Port with 3"-minus subbase and 3/4"-minus aggregate base. Maintain raw materials and finished product stockpiles. 850,000 tons of material produced.
DISMANTLING OF MAGNETIC FUSION TEST FACILITY (MFTF)
LLNL, CA Lawrence Livermore National Laboratory University of California
Dismantled and removal of the Magnetic Fusion Test Facility, a 64-meter-long vacuum vessel containing 26 coil magnets banding the center of the vessel and two 400-ton yin-yang magnet mirrors at either end. The vessel, magnets, and all associated piping and electrical gear were removed from a concrete building that was saved for future use. A laboratory remained active in the basement while the dismantling took place eliminating the possibility of disconnecting the power to the building and an elaborate lock-out/tag-out program was implemented. The end result was over 5,000,000 pounds of stainless steel and copper recovered for recycle. from the project. NOTE: Honored with LLNL Safety Award
REMOVE ABUTMENTS AND RESURFACE IN THE CITY AND COUNTY OF SAN FRANCISCO FROM FREMONT STREET TO MAIN STREET
District 04, Route 880 State of California Department of Transportation
Demolish and remove two bridges abutments, footing, wingwalls. Lead contaminated embankment ramps excavated and disposed of as hazardous waste of varying degrees (Class III To Class I) - over 15,000 tons of material excavated. Performed sitework including paving, sidewalk, curb, and gutter for new parking lot.
