Commercial Building Demolition in Sunnyvale

Tilt-Up R&D Building Demolition in Moffett Park and Peery Park

The typical commercial building we demolish in north Sunnyvale is a one or two-story tilt-up: concrete wall panels cast flat on site and lifted into place, a wood or steel panelized roof with built-up roofing, and a slab on grade. Inside there may be offices, open labs, clean rooms or light manufacturing space. Both Moffett Park and Peery Park are governed by specific plans that encourage replacing these buildings with denser campuses, and in Moffett Park's case, housing as well.

Tilt-up panels are heavy and come down in a planned sequence. We release the roof diaphragm, brace or pull panels inward so they fall onto the slab, then break them into pieces that can be loaded. The slab and footings follow. On a site with several buildings, we phase the work so trucks and equipment have room to move and the owner can keep part of the site active if needed.

Hazardous Materials Closure and Surveys Before Commercial Demo

Before a former lab or manufacturing building can come down, the tenant or owner usually has to close out any hazardous materials permits. In Sunnyvale that runs through the city's fire prevention and hazardous materials program. The owner's environmental consultant typically leads the closure. We coordinate our schedule around it and do not start until it is signed off.

Every commercial demolition also needs an asbestos survey and a Bay Area Air Quality Management District notification. Older R&D buildings commonly have asbestos in floor tile, roofing, wallboard and pipe insulation. That material goes out with a certified abatement crew before anything else happens. Fluorescent lamps, ballasts, mercury switches, refrigerants in rooftop HVAC units and other regulated items are removed and handled as separate waste streams before the building is opened up.

Parts of north Sunnyvale have a history of groundwater and soil contamination from past industrial use. If your site has an existing soil management plan or environmental restrictions, we follow it during slab and footing removal.

Utility Abandonment and Site Controls

Commercial buildings have larger and more complex utility services than houses: high-voltage electrical gear, gas service, domestic water, fire sprinkler lines, sewer laterals and sometimes process drains. PG&E handles gas and electric removal, and the City of Sunnyvale handles water, fire service and sewer abandonment. We plan these with the owner early because they set the start date.

Larger sites need stormwater controls, dust control, and a traffic plan for trucks on busy roads like Mathilda Avenue, Java Drive or Lawrence Expressway. Sites that disturb an acre or more also fall under the state construction stormwater permit. We set up fencing, inlet protection and street sweeping as the site requires.

Retail and Small Commercial Demolition Along El Camino Real

Not every commercial job is a campus. Along El Camino Real and in pockets around Fair Oaks Avenue, older strip retail, small office buildings, gas stations and restaurants are replaced with mixed-use projects. These sites are tighter, closer to neighbors, and often share driveways or walls with businesses that stay open.

We schedule noisy work around neighboring tenants, keep sidewalks open where the city requires it, and stage trucks so they do not block access. Fuel tanks and canopies at former gas stations are removed under their own closure process before the rest of the site is cleared.
