Project Name: Barret Traditional Middle School

Project Description:

Barret Middle School is a three story traditional school that was in need of HVAC renovation. Like most schools in Jefferson County, repairs of this extent had to take place during summer break, which meant that Hussung Mechanical had approximately 10 weeks to complete this project. With 25 plumbers and pipefitters working 6 days a week, Hussung Mechanical replaced 4 boilers, 7 air handling units and 6 pumps. Also, 67 Fan Coil Units and 39 unit ventilators were installed, in each classroom, for individual temperature control. In order to accommodate the renovation of the HVAC system the electrical scope of work included routing power to all new mechanical equipment along with other associated electrical system renovations.
This challenging project required meticulous planning and coordination, from Hussung Mechanical, of 22 subcontractors and vendors

The 10 week time frame also included asbestos removal, demolition of existing HVAC, plumbing, and electrical systems. Approximately 15,850 feet of piping (3 miles) had to be removed and replaced; the majority of this piping was located in 4-foot high tunnels and crawl spaces underneath the first floor of the building. All electrical switch gears, main transformers, and electrical service to the building had to be replaced. Temporary power was required for 5 weeks. This challenging project required meticulous planning and coordination, from Hussung Mechanical, of 22 subcontractors and vendors.


Project Name: UofL Biomedical Research Facility

Project Description:

In the new Biomedical Research Facility, Hussung Mechanical installed five custom built air handling units ranging from 75,000 to 100,000 CFM. Each unit consists of four separate tunnels that can operate independently. There is an additional 15,000 CFM unit to serve the BSL3 Lab on the sixth floor. Ten laboratory exhaust fans were installed in conjunction with two energy recovery units. The office areas are served by VAV boxes with reheat coils while the lab areas utilize Phoenix supply valves with reheat coils. Phoenix exhaust valves were installed for lab general exhaust and fume hood exhaust. Lab gasses, vacuum and water were provided throughout the lab areas to work stations and fume hoods.

The basement area of the new facility is devoted mostly to animal holding and procedure rooms. These areas have extensive automated air pressurization and lighting controls. Also serving this area is an automatic animal watering system. To aid in LEED certification, low flow flushometers were installed on all closets and urinals. AHU condensation and rain water is collected to a harvesting system utilized to provide site irrigation. An Aircuity Optinet Facility Monitoring System was installed to intelligently control each room’s airflow in order to increase safety and minimize energy use.
