Chestnut Street Pump Station (2001)
Renovations to the existing pump house on the Erie Bayfront, with the addition of offices, storage, and a visitor’s area. Our work involved demolition of part of the existing pump station and addition of a new masonry building. The new building re-used the stone archways from the old structure. Work also included new tile roof, new windows, and landscaping.

Johnson Reservoir Geodesic Dome (2008)
This interesting project was done at the Johnson Reservoir in Erie. It involved removing the existing concrete roof structure and replacing it with a new 170' diameter aluminum geodesic dome.
After cutting up and removing the concrete lid, we drained the reservoir. Then the dome was assembled and hoisted up to be set on the reservoir wall.

Erie Wastewater Treatment Plant
We’ve done dozens of projects at the Erie Wastewater Treatment Plant through the years, including work on the new Overflow Retention Facility in 2005, where we modified an existing sludge holding tank into a chlorination tank.
The scope of work included 30’ high concrete baffle walls, 60” diameter piping, and slide gates. Also in 2005, we built concrete duct banks and equipment foundations for an electrical systems upgrade and concrete foundations, paving, and polymer feed system for an equipment building.In 2006, we installed a new 12’ diameter, 18’ deep storm water concrete lift station, complete with valve vault, piping, pumps, and removal of the existing lift station.
In 1980, we built a new 27,000-SF sludge thickener building that included site shoring, massive excavation, slurry walls, dewatering, concrete structure, as well as process equipment, pumps, process piping, and electrical controls.
