Inside the project
Kokosing constructed a new water treatment facility at the Apogee Mine in West Virginia to comply with allowable discharge limits for selenium. This contract consisted of a structural and mechanical construction package including installation of supplied equipment, erection of structural steel and furnishing and installation of interconnecting piping, valves, instruments and all associated supports.
Why it matters
Due to increased enforcement of selenium regulations and understanding of health and environmental effects, proper treatment is critical. One of the major sources of selenium is coal. Much of the coal in the eastern United States is high in selenium and is a major source of selenium for industries heavily involved in the use of coal. This includes mining, refining, coal-fired power and ash landfill. This particular treatment plant technology serves to remove selenium from stormwater runoff.
INSIDE THE PROJECT
The steam system at the McCracken Power Plant at The Ohio State University has utilized water filtration for years, but it was time for an upgrade. This unique project included work primarily in two areas of the 100-year-old building: installing a new condensate return system and installation of a new water treatment system. Completed in two phases, the first phase involved demolition and construction work to install and commission the new boiler water treatment system and condensate return system, while the second phase involved the demolition of the original treatment system. Space was tight, and a Tetris-like method of planning was needed to perform the equipment replacement. Building Information Modeling (BIM) made this planning much easier, since the Kokosing Industrial team could map out the measurements and move pieces into location with greater efficiency.
WHY IT MATTERS
The original Power Plant was completed in 1918 when university enrollment was less than 10,000 students. Since that time the Power Plant’s footprint has grown marginally, yet enrollment is now over 60,000 students. These improvements enable the OSU Central Power Plant to continue serving the campus for decades to come. As demand on the plant’s resources steadily climb, delivering the project on time and within budget was an uncompromising goal for Kokosing.
