The project scope for the historic renovation of a powerhouse building that once powered a textile mill consisted of filtration of 976,000 gallons of contaminated water, abatement of five 2-story boilers, window caulk, and roof.

Alloy Group had the goal to leave the structural steel and four walls of historic powerhouse in accordance with National Park historical requirements.

The Powerhouse University Center Project included various responsibilities, such as:

• Lead removal of the entire building
• Pressure washing of the entire building
• Demolition of seven boiler equipment pads
• Demolition of turbine pads
• Demolition of architectural salvage
• Demolition of catwalks (all interior components)  

• The location of the boiler room (approx. 10’ below grade) created a challenge for moving materials. By cutting a future doorway and creating a ramp we were able to move steel, ACM waste and brick out more efficiently.
• The structure was originally built on an existing spring which caused flooding in the subbasement. Throughout the abatement and demolition, we needed to continually pump out and maintain water levels.
• Because the site is a brownfield site with existing contamination, we worked with our team, the owner, and the city to ensure water could be safely discharged into the sanitary sewer system. Our team designed a filtration system to filter particulates from the water and eliminated any contamination.
• Performing heavy industrial demolition of boilers and steel inside the structure’s tight footprint required us to size an excavator and shear to fit through a roll-up door and ramp down into the basement. Thus, eliminating the need for all work to be completed by hand.
