HGST building 5

HGST Building 5

Hitachi Global Storage Technologies (HGST) is a wholly owned subsidiary of Western Digital that sells hard drives, solid state drives, and external storage products and services. The HGST Great Oaks Parkway Campus are in the process of demolishing several buildings, some of which are in close proximity to an operating FAB (Building 006), which was very sensitive to ground vibration. One such building was Building 005, located approximately 200 feet North of Building 006. Building 005 was a 200,000 SF manufacturing building with an additional 52,000 SF of mezzanine areas. HGST and General Contractor Rudolph & Sletten (R&S) had conducted several vibration monitoring studies to analyze the best possible method of demolishing Building 005 without compromising the manufacturing processes of Building 006.  Based on the recommendation of vibration monitoring studies, the only possible way to demolish Building 005 was to perform the demolition during maintenance shut down. R&S started to search a reputable competent demolition contractor with enough manpower and equipment to take on the task of demolishing 252,000 SF building within 5 days. 

In December 2014, R&S approached Silverado Contractors, Inc. (Silverado) for this project. With a proven track record, Silverado gladly accepted this challenge. Silverado not only provided pricing to demolish Building 005 but also submitted different logistic plans to safely demolish Building 005 within the allocated time.

Bank of America Clock Tower

In order to make way for two new 60 story concrete towers in the new Rincon Hill district of San Francisco, the distinctive Bank of America Clock Tower (formerly the Union 76 Tower) had to be removed. The 240 foot tower was demolished, one triangular shaped floor section at a time. The entire tower was safely brought down to the ground in only 40 shifts. Additionally, Silverado demolished the attached 3 level parking structure and 100,000 square foot office building.






Boarding Area A SFO airport

Boarding Area 'A' San Francisco International Airport

After San Francisco International Airport constructed its new international terminal, the old Boarding Area A impeded the airports expansion to allow more international jetways. Silverado's project managers and superintendents have done extensive work at the airport, and were awarded the contract to demolish the 140,500 square feet boarding area building and its foundation. The extensive foundation system for the rotunda portion was removed in 6 working days, enabling a rapid expansion.
