Project Scope:

Lincoln Landing (formerly Mervyn’s Headquarters Building) consisted of 335,500 square feet of a 4-story office building and an automotive shop located on an 11.33 acre site. AMPCO was contracted to complete the abatement and demolition of the buildings. The environmental scope included asbestos and lead abatement, and removal of miscellaneous hazardous waste left behind by vagrants that had occupied the building while it was vacant for the previous 10 years. Asbestos-containing materials included drywall, floor tile and mastic, pipe insulation, wall mastic and roof mastic. Lead-based materials included paint and ceramic tile.

The demolition scope included the implementation of SWPPP, and the complete structural demolition of the 330,000 square feet Mervyn’s Headquarters building and a 5,500 square feet automotive shop. All building slabs, footings and underground utilities were removed. All concrete was crushed and stockpiled onsite for re-use in the grading scope, totaling 32,300 tons.

Challenges Faced:

The 4-story Mervyn’s Headquarters building east wall was right on the back of public sidewalk. AMPCO employed a structural engineer to provide an engineered structural demolition plan, and then used a HighReach Excavator to demolish the building safely, with no safety incidents, accidents or public property damage.

The Mervyn’s Headquarters east side of the Ground Level had an existing, abandoned utility tunnel that ran underneath the public sidewalk. AMPCO worked with the Client and Public Officials to resolve this issue by using bracing to support the tunnel and public sidewalk during the structural demolition. After the building demolition was completed, AMPCO assisted the Client in slurry backfilling the abandoned utility tunnel
