Project Title:

Central Power Plant Modernization & Infrastructure Upgrades

Client:

Johns Hopkins Hospital

Location:

Baltimore, MD

Summary:

The Principals of the firm have provided continuous infrastructure planning, analysis, design and commissioning to Johns Hopkins Hospital for the past 20 years.  The generation and distribution systems include chilled water, steam, 15 kV electric, emergency power, telecommunications, and domestic water.  The total capital infrastructure expenditures managed by the Principals of the firm exceeded $60,000,000.

The chilled water projects consisted of the addition of 16,200 tons of chilled water generation to the existing central plant.  The project included a new three story, 40,000 SF addition to the existing Central Power Plant (CPP).  This addition was constructed on a privately owned alley within Baltimore City requiring significant public and private utility relocation. 

The first phase of the project was to install four 2,700 ton chillers within the existing plant.  This project from the start of design to the successful operation was completed within a remarkable 14 months.  The first phase was completed in 1998 within the budget of $10,000,000.

The second phase of the project was to construct an addition to the existing central plant and install two additional 2,700 ton chillers.  The plant expansion has space for 7,200 kW of engine generators as well as a 10 MW cogeneration system.  The second phase was completed in 2001 and also was within the budget of $7,000,000. 

Since the plant addition, 3,600 kW of engine generators and a new north campus substation (60 MW) are being installed.  In addition to the chilled water and electric projects, the sequential recase and retube of the five boilers has been successfully bid as well as a state of the art PLC plant control system.
