HVAC Upgrades Ensure Greater Efficiency for Savannah Post Office // April 2017

Energy efficiency is an important priority at U.S. government facilities, but so is serving the public.  MJW Consolidated recently helped the main U.S. Post Office in Savannah, GA accomplish both objectives by completing a major upgrade of the facility’s heating, ventilation and air conditioning (HVAC) systems without disrupting operations.

The 10-month project completed in early 2017 involved replacement of outdated equipment with high-efficiency systems, including two boilers, two chillers, five air handlers and all of the associated pumps and controls. MJW self-performed most of the work and subcontracted with Johnson Controls on system controllers.

The modern boilers save energy through greatly reduced environmental heat loss, the chillers are driven by compressors that use magnetic fields to reduce motor friction, and the new pumps are equipped with variable frequency drives that adjust automatically to demand loads. These advanced features and many others will result in significant energy savings for the 1950s-era facility.

In addition to serving as the main mail distribution center for Savannah, the facility provides lobby service to postal customers.

“Completing the project while allowing the facility to continue performing its vital role in sorting and distributing mail, as well as serving the public, was vital to the client and to us,” said MJW project manager Ralph Harrison. “Our project supervisor, Wade Douglas, myself and the entire team worked closely with the post office staff to ensure safety and continuity of operations."


MJW Audits Fire Systems for Westinghouse Nuclear Sites // March 2017

MJW Consolidated has completed a comprehensive fire hazard analysis (FHA) at two Westinghouse Electric Company facilities in western Pennsylvania that provide critical services to the nuclear energy industry.

The purpose of the two analyses was to ensure compliance with fire protection and suppression measures required under National Fire Protection Association (NFPA) standards for nuclear facilities of all types. The FHAs were performed at a Westinghouse facility in the George Westinghouse Research and Technology Park in Churchill, PA which performs structural and chemical integrity testing of small samples of material used in the construction and operation of the nuclear reactors, and at the Westinghouse Waltz Mill, PA site which performs decontamination, repair, modification, assembly, and checkout of equipment and systems used to service and operate nuclear power plants handles operating and servicing equipment used at nuclear energy facilities.

Performance of a nuclear facility FHA requires specialized knowledge of industrial fire protection engineering that few companies are qualified to perform. The Westinghouse FHAs required MJW to evaluate the condition of structures and processes within both sites’ radiologically controlled area boundary, with particular attention to the separation or control of hazards; the control or elimination of ignition sources; and the suppression of fires. The goal of the audits was to confirm compliance and identify any areas that might be in need of attention. Ultimately, an FHA ensures the possibility of injury to people or damage to facilities, equipment or the environment is within acceptable limits.

MJW is well qualified to perform nuclear facility fire system audits because of its combination of capabilities in large scale fire suppression design and installation services, in major industrial construction projects, and in engineering services for both fire suppression and construction projects. The successful completion of the FHA represents an expansion of MJW’s partnership with Westinghouse and provision of services for the nuclear energy industry.
