7 Hillsborough Elementary School Renovations 7/25/2002 Preliminary Report on Existing Facilities Page 3 • An interior that was renovated about 12 years ago. Acoustical tile ceilings anc r,Pr:c wire installed in all the classrooms. Cabinetry is inconsistent through the building. A data closet was introduced onto the corridor cutting into one of the larger classrooms. • A building program that includes classroom space for kindergarten and first grades, the school's music classroom,and a Reading Recovery room. Two of the three kindergarten classrooms are adequately sized. One of the three kindergarten classrooms and all three first grade classrooms are very small and do not meet NCDPI guidelines for primary classrooms. • Interior partitions that are primarily 4"concrete masonry. The doors and door frames are predominately original. The floors are mostly viayl composition file(some placed over vinyl asbestos tile)in corridors,and a mix of carpet and vinyl composition tile in the classrooms. Quarry tile is used in the group toilet rooms. • Odors emanate from various rooms around the building. More than likely,these smells are caused by water penetration from the 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. The HVAC system consists of a two- pipe,hot water heating system that emanates from the boiler room located below the cafeteria. Insulated and jacketed hearing pipes,that replaced the ruptured,underground steam pipes in 1997,travel across the existing covered walkways and enter the building on the west end of the building. The cold water cooling system begins in the cooling tower located north of the building, is pumped from a mechanical room in the 300 building and circulates through unit ventilators located on the floor of each classroom The 300 Building opened in 1959. The original floor plan appears to have been designed for primary classrooms. The Orange County School's Support Services Department is currently using the building for office and storage space. The 300 Building exhibits the following features: • A one-story, lightweight,structural steel forme with a concrete slab floor and a "Camesto 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 windows under the sills are made up of a 4"concrete masonry unit,a W' air space and a 4"exterior brick. The original windows were replaced in about 1990 with a thermally unbroken aluminum window system. During site investigation,it was noted that the weepholes(holes that allow the air cavity to release water)in the exterior walls were small holes(about the diameter of a pencil)and could be clogged easily. • A roof that is serviceable. It appears to be a modified bitumen roof with a granular cap sheet, and according to school system records, it was replaced in 1994(8 years old). The original 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 • An interior that has been renovated piecemeal over the past 12 years ago. Interior finishes and cabinetry are inconsistent throughout the building. • Interior partitions that are primarily 4"concrete masonry. The doors and door 5rarnes err predominately original. The floors are mostly vinyl composition file(some placed over vinyl asbestos tile) in corridors,and a mix of carpet and vinyl composition file in the classrooms.
