Kern Power Plant

Silverado Contractors performed this project for PG&E. This was the third contract for PG&E on the same property. In a previous contract we removed the old boilers. The scope of work was underground removal. At the surface, the abandoned boiler foundations resembled a giant concrete checkerboard with dirt in the squares, just a hint of what was below. Other remains of the old plant poked up from the dust – a big concrete pad from a motor, a pair of smokestack foundations, and a building foundation from the old Quonset huts we’d torn down years ago. Off to the North, the tank farm stood vacant, its tanks removed; the earthen dikes broken through. We removed 120 truckloads of concrete checkerboard buried five feet in the earth. Along the way, we ran into old asbestos transite ducts, hauled off 100 truckloads of contaminated dirt, graded and backfilled 17-acres of blown dust and capped it all off with a soil binder approximately nicknamed “gorilla snot”. The schedule was 40 days.

We performed the work in less time. We moved in 380,000 lbs. of heavy equipment: a Liebherr 974 Excavator for the breaking and a Link Belt 800 Excavator for the digging and built it all up out of five semi-truck loads of parts and pieces. We added a 15,000 lb. HB 7000 Hammer standing twice the size of a man with a chisel as wide as a coffee can. We brought in our subcontractors early and worked simultaneously. We made the decision to take the foundation down to top of the old mat slab to a convenient breaking point simplifying the process. Silverado completed the project safely, within time and within budget.



South Bay Power Plant

Contracted with Dyngegy to demolish this sixthy year old decommissioned power plant and associated buildings. Activites began by isolating and terminating utilities. Hazardous materials abatement followed to make sure all materials were then safe for removal. Preparing the structure over the next several months for eventual implosion soon followed. The 750 mega-watt plant had four boilers with four 140' tall stacks. The entire structure itself was approximately 100' wide and nearly 400' long. Demolishing SBPP proved a daunting task. Due to the plant's location on the coast and active switching station, it was imperative that the immediate environment was not affected. Located near the water, there were a lot of obstacles to overcome from local community concert to multiple agency requirements. Dust and debris control were also paramount to the success of the project. A comprehensive and formalized demolition plan and site logistics plan were put into effect immediately to help mitigate any potential concerns. 

During preparation for the implosion, demolition of the turbine generators, their platforms and pedestals proceeded. An admin building, electrical shop, exterior catwalks as well as ground level equipment were also removed. Two 5 million gallen fuel oil tanks just south of the power plant were removed as well. The implosion took place on Saturday, February 2, 2013 at 7am by Dykon Blasting Company. Thousands of spectators arrived early to witness the event. Once the structures were down to a manageable size, our field crew, operators and labors, worked tirelessly to proceed the twisted tons of steel into smaller pieces, load the pieces onto trucks and off to the recyclers. Approximately 20,000 tons of steel was recycled. Another successful project.


PG&E - Humboldt Bay Power Plant

Silverado performed the dismantlement of Fossil Units 1 and 2 for PG&E at their Humboldt Bay Nuclear Power Plant located in Eureka, California. Silverado's full service contract took the plant from fully operating through the cold and dark process, abatement and cleaning of all hazardous materials and oils, dismantlement of all structures, final site cleanup, and grading operations. Included in the scope of work was the complete removal of the three million gallon liquid fuel tank, system, and associated piping. In addition Silverado was able to facilitate for the client a beneficial asset recovery program. Silverado completed the complex project ahead of schedule and with over 50,000 man hours expended had not a single accident or even a first aid incident. All work was performed directly adjacent to the Unit 3 Nuclear Reactor, which required daily coordination with the Nuclear decommissioning team at this high-level secured site.


Morro Bay Power Plant

Silverado removed all six of the fuel oil storage tanks that supplied the Morro Bay Power Plant. The tanks combined capacity was 34 million gallons. The tanks were located in an extremely ecologically sensitive sand dune with endangered species. The site was also an Indian heritage site, which required coordination with the onsite Indian representative.

The Morrow Bay Power Plant - Fuel Oil Tank Farm decommissioning consisted of the demolition of six above ground fuel oil tanks including one with a secondary containment unit with a floating lid. Each of five of the tanks had a capacity of 159,000 bbls with fixed roofs and one 54,000 bbls tank with a floating lid. Over the course of the project Silverado had to be careful not to endanger the local habitat and make sure the environment surrounding the tanks was not disturbed in any way. To help make sure this was accomplished, Silverado placed 100, 1.0" thick, 8x20 steel plates strategically throughout the tank farm basin. All of the tanks were demolished on site with all the metals processed for recycling.

GE Nuclear Test Stand

General Electric contracted Silverado to demolish a nuclear reactor test tower at the GE Nuclear Facility in San Jose. The scope included dismantlement of water supply piping, the gantry service crane for the test vessel and the surrounding five story tower.
