Northwest Demolition was contracted for the removal of heavy equipment inside of an underground military installation dating back to the 1930s.  The project scope spanned over 20,000sf across four individual rooms, including the demolition and removal of a myriad of switchgears, compressors, chiller units, storage tanks, overhead structural steel framing and piping, as well as several large turbine generators, including one weighing over 65,000 lbs.  The presence of combustibles and other potential environmental unknowns dictated that removal operations could not be spark-generating.  Additionally, the limited ventilation/exhaust capabilities of the tunnel environment prohibited the use of combustion engines.  As a result, Northwest Demolition mobilized a fleet of specialized equipment, including a demolition robot and electric-powered skidsteer, and a skilled mechanic crew to perform the removal operations as efficiently as possible.

The sensitive nature of this high-profile, time-critical project required significant logistics planning to coordinate concurrent operations with abatement and electrical contractors also working inside the tunnel system.  Northwest Demolition completed the project without a safety or first aid incident and nearly one month ahead of schedule.
