As part of our Engineering On-Call Engineering Services contract, AIE has provided MEP/FP engineering design services for the following assignments:

Kennedy High School Air Handling Unit Replacements, Waterbury, CT: AIE provided design services to replace (15) air handling units, (2) condensing units, and a mini-split system that served the building. The units consisted of a mixture of heating only, and cooling/heating air handlers. In addition, air conditioning was added to the Swimming Pool and Locker Room areas. All new HVAC equipment was integrated into the existing Building Management System, and new ductwork was designed to connect the new equipment to the existing systems. In addition, structural dunnage support was designed for new HVAC equipment.

Wilby High School Air Handling Unit Replacement, Waterbury, CT:  An air handling unit (AHU) that supplies a Music Room and common spaces was not providing heat or cooling to the areas. The AHU’s steam coil and chilled water coil were unusable and leaking, and the supply fan was inoperable. AIE provided design services to replace the AHU and specified new duct insulation to meet the requirements of the Energy Conservation Code. 

Crosby High School Cooling Tower Replacements, Waterbury, CT:  The building’s (2) existing cooling towers were part of a water-cooled, (2) 250 Ton chilled water system in the basement of the school. Both cooling towers were in a state of disrepair, and have never functioned properly. The cooling towers are difficult to access for maintenance and consistently required to be drained down during the winter months. AIE provided design services to replace both cooling towers to provide a fully functioning system. Maintenance and accessibility were taken into consideration when designing and specifying new equipment. 

International School Boiler Replacement, Waterbury, CT: AIE provided a design to replace two oil-fired steam boilers with three natural gas boilers, utilizing N+1 redundancy configuration. The existing building had a mixture of hydronic and radiator heating.  Hydronic heating utilizes old pneumatic controls. AIE’s design replaced the radiator heating with hydronic heating and replaced the pneumatic controls with an electronic control system. The boiler system was designed so that it could be shut down during the summer months.
