6 Hillsborough Elementary School Renovations •7/25/2002 Preliminary Report on Existing Facilities Page 2 E drainage. Tapered insulation and large,galvanized steel gutters were added during the reroofing to provide minimal slope and to collect the rainwater and divert it to the grade. According to The Garland Co..,a roofing consultant that assessed the condition of the roof earlier this year, the existing single-ply roofing membrane and the roof insulation needs to be replaced and the perimeter flashing needs major repairs. • An interior that has not changed significantly in 40 years. Metal lockers line the corridors. Some of the existing home economics cabinetry is still in use. • A building program that includes classroom space.for grade two through five, the school's media center, the school's administrative offices and the data distribution room. The building serves the program adequately,but does not meet NCDPI guidelines for school construction. A computer lab located near the media center works well,and a campus television studio which is prized by school staff. • Interior partitions that are primarily 8"concrete masonry. The doors and door frames are predominately original. The floors are mostly vinyl composition tile(some placed over vinyl asbestos tile) in corridors and storage rooms and carpet in the classrooms, offices and media center. An elevator with a first floor machine room was added in 1990. • Odors emanate from various rooms around the building. More than likely,these smells are caused by water penetration from the roof,walls, windows or other source,and mold. • A lack of ventilation. When the air conditioning was provided.in 1990,no ventilation vents were created for the unit ventilators in the classrooms or offices. The HVAC system consists of a two-pipe heating system and a two-pipe cooling system that feeds unit ventilators located on the floor in each room The boiler is located in the old boiler room. • A rodent problem. Rodents from the boiler room travel along the pipe chase along the north side of the First floor. The 200 Building opened in 1952. The 200 Building exhibits the following features: • A one-story, lightweight,structural steel flame with a concrete slab floor and a"Cemesto Insulation Roof Deck". • An exterior wall consisting of 12"thick masonry end walls,8 W'thick masonry walls below window sills and aluminum windows that extend the length of the building. The walls at the ends of the building are made up of a 8"concrete masonry unit and a 4"exterior brick and, the walls under the sills are made up of a 4r concrete masonry unit,a rh"air space and a 4" exterior brick. The original windows were replaced in about 1990 with an aluminum window system that allows heat to transfer through the window frames. During site investigation, it was noted that the weepholes(holes that allow the air cavity to release water) i.. .he Lxtrerior walls were small holes(about the diameter of a pencil) and could beclogged easily. •, A rooPthat has reached its useful life and needs to be replaced. A four-ply,coal tar built-up roof that was replaced in 1984(18 years old). The origins!roof deck was truly flat and has no gutters or other internal drains,so the rainwater drains off the edge of the roof onto the ground. According to The Garland Co.,a roofing consultant that assessed the condition of the roof earlier this year,the existing built-up roofing and the roof insulation needs to be replaced and the perimeter flashing needs minor repairs. According to the consultant's report,there are two roof layers that must be removed prior to reroofing of the building. (919) 942-8586 Telephone R051602existingfacilities.doe (919)929.4802 Pax
