US COAST GUARD AIR STATION SAN FRANCISCO SEAWALL REPAIR

  • SAN FRANCISCO SEAWALL REPAIR
  • Client: US Coast Guard
  • Location: San Francisco, CA
  • Date: 2005
  • Contract #: HSCG88-05-J-623009
  • Value: $647,155

Project Details

Cerrudo Services repaired 800 feet of riprap and approximately 325 feet of concrete curb paving at the US Coast Guard Air Station in South San Francisco.  A seawall protects the Air Station flight line and parking lot from tidal erosion and wind waves.  Rip rap consisted of 1,500 tons of 200 lb class and ¼ ton class stones.   The curb repair required the demolition of a 20” high existing curb and 1,650 SF of asphalt with underlying concrete slab.  Unlike the demolished curb, the new curb and slab contain rebar reinforcement.

Communication and coordination with the Air Station was critical to the success of the project.  Due to the frequency of HH-65 Dolphin rescue helicopter operations in and around the construction site, an ongoing exchange of schedules and work plans from both Cerrudo Services and the Coast Guard were crucial for maintaining construction deadlines and work site safety.  The use of heavy equipment, the dumping, loading, and hauling of materials, and riprap installation all occurred in Coast Guard fueling areas and rescue helicopter flight paths.  The overlapping of construction efforts and helicopter operations required meticulous attention to job site cleanliness to eliminate any potential foreign object damage to the helicopters.

 

NAPA CONCRETE RUBBLE REMOVAL

  • Client: US Army Corps of Engineers
  • Location: Napa, CA
  • Date: 2001
  • Value: $ 72,853

Project Details

The Sacramento District Army Corps of Engineers began construction of the Napa River flood protection project with Contract 1 A in August 2000. Work was completed in October and concrete rubble was left at the edge of the lower terrace. The material appeared to be old highway concrete bridge railing and concrete paving, with more than 250 pieces ranged in length from three to eight feet in diameter and 3.5 feet high. The rubble protruded above the surface of the marsh plain terrace. At higher tides this rubble was covered by water, making it a navigational hazard for small craft.

As prime contractor, Cerrudo Services removed all concrete rubble that protruded one foot or more above the edge of the marsh plain terrace, approximate elevation 0.0 NGVD on the West bank of the Napa River from C-Line Station 32+00 to 52+00 (River Station 640+00 to 659+00) without disturbing the marsh plain sediment and worked around endangered species and wildlife habitat without impact. Approximately 176 tons of concrete were removed and recycled.
