Building Addition and Renovation
This project included the engineering for an addition to and renovation of a two-story, 16,700-square-foot office building in downtown Indianapolis, in support of a local architectural firm. The HVAC design included the addition of three new rooftop gas-fired air handling units and associated distribution ductwork to serve the new addition. The electrical design included new lighting throughout the building, a new electrical service, voice/data cabling, and video conferencing planning. One of the primary engineering challenges was mechanical and electrical design considerations to support the glass-enclosed, two-story entrance and conference room. Estimated mechanical and electrical construction cost was $550,000. Project construction was completed in February 2003.
Indiana State University
Chilled Water Study
Applied Engineering was retained by Indiana State University to analyze their existing chilled water system. The chiller plant has a capacity of 5,200 tons and is able to thermally store cooling at night through a bank of ice storage tanks (15,750 ton hours available). The existing plant is nearly at capacity, and there are new building plans for the campus. The existing ice storage was analyzed to determine the long-range effectiveness of ice storage and peak capacity of the plant under a new operating philosophy. The load profile was analyzed to determine pressure and temperature requirements at the existing building connections. The distribution system mains were analyzed to determine the hydraulic characteristics associated with each connected building and identify pinch points in the system. Finally, new locations were investigated to develop an option for the addition of a satellite plant on the west side of the campus to serve additional load. All findings, calculations, observations, conclusions, and recommendations were summarized in a bound report that was completed in early 2005.
Indiana University / Purdue University at Indianapolis
Barnhill Parking Garage
This project included the engineering for a new 1300-car, five-story parking garage on the IUPUI campus in downtown Indianapolis. The mechanical design included a dry pipe fire protection system and the floor wash down system. The electrical design included the primary and secondary electrical service, power distribution, interior and exterior lighting, and telecommunication systems. The internal lighting of the structure included day lighting control as an energy savings measure. Communications included fire alarm and a patron emergency telephone system. The overall construction cost was $10.9 million, with the estimated mechanical and electrical cost at approximately $1.1 million. Project construction was completed in August 2004.
Purdue University
Steam and Condensate Flow Modeling Study
Applied was retained by Purdue University to complete a steam and condensate flow model for their West Lafayette, Indiana campus. The Purdue steam distribution system consists of two services (125 psig 600°F superheated steam service and a 15 psig 450°F steam supply) serving a total peak heating load of 237,500 MBH. This includes a total of 225 buildings on the campus and approximately 16.5 miles of pipe ranging in size from 18 inch to 4 inch. In addition, there are 16 locations throughout the campus where the high pressure steam line is reduced to 15 psig through PRV stations that feed the low pressure system. Condensate is pumped back to the steam plant by means of a condensate return system, which is returned at a rate of approximately 90% to 95% of steam load. The project scope included five phases — software evaluation, test model, model building and calibration, report completion, and training. Applied utilized the KYPipe® software program for both steam and condensate models. This study was completed in June 2004.
This project was awarded a Merit Award from ACEC Indiana in its 2005 Engineering Excellence Awards Competition.
