Timberland High School’s 17-year-old heating, ventilation and air condition (HVAC) system is being replaced with minimal interruptions to academic instruction, according to Berkeley County School District press release.
“Minimizing interruptions to instruction as much as possible is a constant focus while proceeding with our construction projects,” BCSD Capital Projects Manager Connie Myers said. “At Timberland, we are working to ensure that much of the noisy and disruptive work – including cutting, grinding, hauling off, and placing concrete – is taking place when students are not in the building.”
Six classes were temporarily moved to trailers.
During the district’s winter break, the contractor mobilized, removed ceilings, installed concrete equipment pads, opened access in the attic space, and installed lighting in the attic space.
The contractor also began running large electrical conduits, installing loop piping for the water source heat pump system, and fabricating ductwork.
The complete project will result in the school’s current HVAC system being replaced with a more reliable and efficient water source heat pump system. The new system will allow individual classroom control and better meet the demands of the school, according to the district.
The replacement increases fresh air intake — as required by recent building code changes — and will provide better indoor air quality. The new, two-pipe system will have individual units for each classroom with new boilers and a cooling tower.
The cooling tower will be connected to a special water meter in order to avoid unnecessary sewer charges.
For this project, BCSD used the Integrated Project Delivery System (IPDS), a procurement method that allows the owner, designer and contractor to identify and resolve problems before construction starts.
This system allowed the designer (RMF Engineering) and the contractor (Thompson-Turner Construction) to work collaboratively on day one. The maintenance department was able to carefully review the design to ensure that all necessary features were incorporated into the design. All parties met frequently to problem solve and discuss the various options.
Phase I is expected to be the longest phase of the project and is scheduled to be complete around March 1. During the next phase, teams will move the six classrooms that had been temporarily displaced back into the building, so that another six classrooms may be moved to the trailers.
The construction continues in phases until the summer. During summer months, HVAC equipment will be replaced in the gymnasium, auditorium, cafeteria and office areas so the entire system is installed before the start of next school year.
