Vance-Granville Community College- Henderson, NC
HVAC and Fire Alarm Study and Replacements in Multiple Buildings

EDi completed a study for VGCC evaluating the existing HVAC & Electrical systems for 7 of the 10 main campus buildings, and Fire Alarm systems for all 10 buildings. The majority of buildings were originally built in the mid-1970s and include classrooms, vocational shops, administrative, bookstore, lecture halls, daycare, and civic center functions.

As part of the study, priorities were developed based on the age of equipment, building use, and construction schedules. EDi created cost estimates for each of the buildings including HVAC system replacement and associated electrical work, complete lighting fixture replacement, and fire alarm system replacement. In addition, an asbestos assessment was performed to determine the existing conditions of the buildings and to develop the costs to be included in the overall project budget. Based on these developed priorities and costs, the design phase scope of work and associated project/construction schedules were developed that met the College's budget and needs.

The project is currently in the first phase of design, which is the fire alarm system replacement for all 10 buildings. Based on the coordination with the College's classroom and facility schedules, the construction is targeted to begin in May 2019 with the majority of work completed during the summer session. The HVAC/Lighting Replacement construction will be completed in a separate phase during the summer of 2020 for two of the campus buildings. The existing HVAC system for the 35,000 sq. ft., 3-floor Bookstore, Lecture Hall, LRC building consisting of a multi-zone AHU, air-cooled chiller, and gas-fired boiler system will be replaced with a DX-cooling VAV system with high-efficient gas-fired boilers. The 23,500 sq. ft. Classroom, Office and Daycare building has existing humidity issues with the HVAC system consisting of multiple blower coil units. The system will be replaced with a DX-cooling VAV system with individual AHUs for the separate functions within the building and gas-fired boilers. The existing fluorescent light fixtures will be replaced with high-efficient LED fixtures throughout both buildings
