ST. LOUIS - Mechanical contracting company Haberberger Inc. has announced it soon will begin work on three recently awarded projects for Lemay Wastewater Treatment Plant and the main branch of the U.S. Postal Service here.

Haberberger recently was hired by Tarlton Corp. to work on a wet-weather expansion project for the wastewater treatment plant. The project involves the construction of four primary clarifiers, a primary sludge pump station and a grit building. Led by general superintendent Phil Jones and project manager Jeff Roberts, the Haberberger team also will upgrade the plant’s HVAC system, replacing associated pipe valves and fittings. Construction is expected to be completed in December 2009.

Haberberger also has been enlisted for work on two separate projects for the post office. The first project involves upgrading the air-conditioning in the emergency power storage area in the UPS IPSS room. During the second project, Haberberger will be in charge of replacing all of the heating and ventilation units in the vehicle maintenance facility’s maintenance garage. Charlie Bott, general foreman, and Mike Conway, project manager, will be heading up the Haberberger team for the projects. J.E. Novack Construction Co. is serving as the general contractor for the UPS IPSS room construction, and Klinger Construction Co. will act as general contractor on the vehicle maintenance facility project. R.F. Meeh Co. has been hired for the sheet metal contracting work on both projects, which are expected to be completed by May 1, 2008.
