Demolition Contractor in Moffett Park, Sunnyvale
Moffett Park is the large office and R&D district in north Sunnyvale, between Highway 237 and the Bay, next to Moffett Field. Its specific plan is reshaping the area, and that means older buildings and the acres of asphalt around them have to come out first.
Why Moffett Park Buildings Are Coming Down
Much of Moffett Park was built out over several decades with one and two-story R&D buildings and low office buildings surrounded by surface parking. The district's specific plan, updated in recent years, allows much denser development and opens parts of the area to housing and new public open space. Owners are replacing older buildings that no longer fit modern tenants, or assembling parcels for larger campuses and mixed-use projects.
For a facility manager, that often starts with a vacant building after the last tenant has moved out. Before redevelopment, the owner may want the building down to cut security, insurance and maintenance costs, or the new project's schedule may call for demolition as the first phase. Either way, the steps are similar.
Pre-Demolition Work on Moffett Park R&D Buildings
Former R&D and manufacturing tenants in this district often used regulated chemicals. Before demolition, the tenant or owner closes out hazardous materials permits with the city, usually led by an environmental consultant. Some Moffett Park parcels also have soil or groundwater restrictions tied to past industrial use, and those rules carry through to how slabs and footings are removed.
An asbestos survey of the whole building comes next, covering roofing, flooring, wallboard, mastic and pipe insulation. A certified abatement contractor removes anything positive. Lamps, ballasts, refrigerants in rooftop units, batteries in backup systems and other regulated items are pulled and handled separately. With all of that documented, the air district notice and the Sunnyvale demolition permit go in, and structural work can begin.
Structural Demolition and Parking Lot Removal in Moffett Park
Tilt-up concrete panels, steel frames and panelized roofs come down with large excavators and shears, in a sequence planned around the site layout. Concrete is broken, steel separated, and both sent to recycling. Slabs and footings come out to the depth the new design calls for.
The parking lots are often the larger quantity. Moffett Park sites can have acres of asphalt with landscape islands, light poles, storm drain inlets and buried irrigation. We grind or break out the asphalt depending on whether the base is reused, keep it separate from concrete for recycling, and protect inlets because storm drains here flow toward the Bay.
Site Logistics Near Moffett Field and Highway 237
Truck access in Moffett Park is good, with Mathilda Avenue, Java Drive and Highway 237 close by. We still plan haul routes so trucks avoid peak commute periods and the VTA light rail crossings that run through the district. Neighboring campuses often stay occupied, so we fence work areas and keep shared driveways clear.
The district sits next to Moffett Field. Tall cranes or equipment near the airfield can require aviation review, which is usually handled by the general contractor for the new building. For demolition, we keep equipment heights within what the site allows and let the owner know early if anything could trigger that review.

Demolition FAQs
Moffett Park Demolition FAQ
What has to happen before an R&D building in Moffett Park can be demolished?
Hazardous materials closure, an asbestos survey and abatement, removal of regulated items, utility disconnects, air district notice and a city demolition permit. We coordinate the order.
Can we demolish before the new project is fully approved?
Sometimes. Owners often demolish vacant buildings to cut holding costs. Check with your planning team, since some approvals tie demolition timing to the new project.
What drives cost on a Moffett Park demolition?
Building size and construction type, hazardous and regulated materials, soil restrictions, the area of asphalt and concrete, and phasing around occupied neighbors.
How much of the site gets recycled?
Concrete, asphalt and steel make up most of the weight and recycle well. We separate materials on site and keep tonnage records for the city.
Do you work with our environmental consultant?
Yes. On sites with soil management plans or closure requirements, we follow the consultant's procedures for excavation, stockpiles and testing.
