The Johns Hopkins University Applied Physics Laboratory Building 13 Central Mechanical Plant (CMP) was originally designed by Henry Adams in the mid-1980s. Since then, the firm has done several small modifications ending with the replacement of the four 800 ton cooling towers with four 900-ton cooling towers.

The CMP delivers chilled water and condenser water to 620,000 SF of office, lab, cafeteria and other support areas of seven buildings within the South Campus. The current CMP is comprised of two 350-ton ice maker chillers with an ice storage capacity of 8,500 ton-hours and heat exchanger capacity of 1,900 tons; two conventional 550 ton chillers and four 900 ton cooling towers. The plant maximum pumping output capacity is 2,100 tons of chilled water and 3,100 tons of condenser water.

Building Information Modeling (BIM) software was utilized to create a 3-dimensional model of the existing conditions.  This model was utilized to complete the four major construction phases necessary to keep the plant functional while replacing the pipe, equipment, etc.
