CAMI Assembly Plant

Scope of Work
The subcontract work involved the selective demolition and removal of the old paint shop, encompassing an area of approximately 188,000 square feet. Key requirements included:

• Preserving the structural integrity of the main building’s framing and services.
• Protecting adjoining areas of the plant during demolition activities.
• Removing redundant equipment and structures, including paint booths, ovens, conveyors, mezzanines, support structures, and associated mechanical and electrical systems.
• Cleaning pits and removing 25 roof stacks, some extending up to 75 feet above roof level.

Project Execution
Planning and Preparation
Delsan-AIM developed comprehensive plans and procedures before commencing work. The site was set up with a trailer complex, equipment, and scrap laydown areas secured by construction fencing to isolate operations from ongoing plant activities.

Demolition Activities
A combination of mechanical and manual demolition techniques ensured efficient and safe execution:

• Mechanical Demolition: Utilized a fleet of 16 mid to large excavators supported by front-end loaders, skid-steer loaders, telescopic handlers, forklifts, and ride-on sweepers for demolition and cleanup.
• Selective Demolition: Workers employed 14 elevated work platforms (60’ to 80’) and cutting tools, including reciprocating saws and torches, for precise separation of equipment and final trimming work.

Stack Removal
Delsan-AIM safely removed 25 stacks using a 500-ton mobile crane with a luffing jib. The furthest stack, located 265 feet from the building edge, was dismantled following an engineered lifting plan.

Material Management
Debris and scrap materials were processed and managed with efficiency:

• Five roll-off trucks transported demolition debris to an on-site laydown area for sorting and processing.
• Materials were then shipped off-site to licensed recycling or disposal facilities.

Project Success
Delsan-AIM executed the project within the required timeframe, employing advanced demolition techniques, detailed planning, and a strong focus on safety. This efficient operation ensured minimal disruption to ongoing plant operations while meeting the client's needs for the new paint shop installation.
