Johns Hopkins Wyman Park Boiler Plant, Baltimore, Maryland

Mechanical Systems Design & Installation: Piping, Boilers & HVAC Systems

The Industrial Facility Project

Johnson Controls, Inc. was contracted by Johns Hopkins University to renovate and upgrade the existing steam plant to a central heating plant. The existing plant serviced the former Marine Corps Hospital located in the Wyman Park campus that is now owned by the Johns Hopkins University. The upgrade of the steam plant was part of Johns Hopkins University’s redevelopment plan for the Wyman Park campus. The steam plant provides heat to radiators during winter months and general domestic hot water through existing heat exchangers in the summer months.

Poole & Kent Mechanical Contractor Role

In our role as the mechanical contractor, Poole and Kent worked with Ross Infrastructure to complete the design and installation of the following mechanical systems/equipment:

• Removal of three existing steam boilers and piping; and
• Installation of two new 200 HP / 6,700 MBH hot water boilers and one new 30 HP / 1,050 MBH steam boiler.

The new HVAC system was connected to the existing medical center by new underground piping between the boilers and the building and routed to the 8th level attic space connecting to existing pumps and piping. The hot water piping was also routed to the building’s west mechanical room to generate domestic hot water through a heat exchanger for the winter.

Challenges/ Achievements/ Goals

Poole and Kent commenced work in the spring of 2005 and maintained a fast-track project schedule in order to complete work in October 2005 prior to the winter season.
