Project Title:

South of Orleans Expansion - Energy Plant

 

Client:

Johns Hopkins Hospital

 

Location:

Baltimore, MD

 

Summary:

This project consisted of a new 51,800 GSF Energy Plant to be contained within a new parking structure located on the southern portion of the hospital campus.  The Energy Plant is designed for a final build-out of 21,000 tons of chilled water generation, 40 MVA of electric distribution, and 9.0 MW of electric on-site generation. 

The ultimate chilled water capacity of the plant is 21,000 tons (6 chillers @ 3,500 tons each).  The total campus generating capacity will increase to 56,000 tons of refrigeration.  The design of this plant is to operate in conjunction with the existing central plant.  The south energy plant utilizes variable primary flow.

The project included the re-distribution of entire campus 15 kV service by means of distribution through the existing Baltimore City streets and passageways.  The project also included a replacement of the existing hospital’s 3.6 MW, 480/277 volt emergency distribution substation with a central emergency power center.  All back-feeding and service replacements are to be performed while maintaining building occupancy with minimal disturbance to building occupants.   The project includes a new addressable fire alarm system which is connected to the existing campus network.  This system is capable of transmitting all trouble and alarm signals back to the existing central campus monitoring station. 

The design was started in November 2002 and completed in August 2003.  The project was recently bid and awarded within the budget of $41,000,000.  The project is currently under construction.  Construction is scheduled for completion summer 2005.
