St. Louis-based mechanical contractor Haberberger, Inc. was recently recognized by the Associated General Contractors (AGC) of St. Louis for its work on Ameren Missouri’s Maryland Heights Renewable Energy Center. AGC St. Louis presented Haberberger with a Keystone Award at the 16th annual Keystone Awards ceremony in November. The annual awards honor St. Louis construction firms for their achievements in building the facilities that support and enhance the quality of life in Greater St. Louis.
Haberberger was recognized as a Specialty Contractor/Subcontractor in the category of Industrial/Infrastructure projects over $5 million. A five-judge panel selected Haberberger and the other winners based on the challenges each firm faced during construction and their effectiveness in achieving solutions.
Haberberger, which oversaw work on the mechanical, plumbing and HVAC systems during construction of the Renewable Energy Center, was faced with a very challenging schedule, with over 800 RFI’s (request for information) and 176 piping design changes. Even with these challenges, Haberberger was able to complete the project 108 days ahead of schedule and under budget. The project was completed in 2012.
The Maryland Heights Renewable Energy Center is located in Champ, MO, at the IESI landfill and is one of the largest landfill gas-to-electricity generating energy centers in the US. The landfill generates methane gas, which is collected and used in gas turbine generators. These generators produce 15 megawatts of electrical power, or enough for roughly 10,000 homes.
Haberberger’s team on the project was led by Project Manager Pat Reilly, Pipefitter Superintendent Tim Waldorf and Sheetmetal Superintendent Dan Hancock. Construction management and engineering was overseen by HR Green, of St. Paul, Minn. Subcontractors included Bieg Plumbing, Dynamic Controls and Thornburgh Insulation.
