iQ DALLAS BRICKHOUSE, JR., PE CONSULTING ENGINEER 1012 Bayfield Drive Raleigh, North Carolina 27606 (919) 851 -2465 / Cell (919) 302 -8728 Email: gdbrick2 @yahoo.com September 6, 2012 Mr. Derrell Mullins, AIA Mullins- Sherman Architects 1503 Old Catbonton Road Sanford, NC 27330 Re: Inspect Two Building Structures 1254 Sanford, NC Dear Mr. Mullins: As requested, the undersigned visited two buildings in Sanford to perform a structural inspection and review of the condition of the existing building structures for possible purchase by Lee County. The two buildings are located at 408 Summit Drive and 130 Steele Street in Sanford, NC. They are currently privately owned. The following structural observations were noted during this inspection: 408 Summit Drive: I This 1980's vintage building structure is steel framed with steel joist girders, steel joists at approximately 4' -9" to 5' -0" on center and steel columns along the exterior walls and at the center of the building. The roof is exposed metal deck, trapezoidal rib, Galvalume coated, steel roof panels, 2' wide, over standard plastic faced, metal building insulation draped over the steel joists with a center ridge cover in the long direction of the building, similar to a pre - engineered metal building. The Galvalume finish on the roof deck looks to be in good condition. There are gutters on the two long sides of the building. The footprint of the building walls is approximately 121' -6" x 81' -6 ". There is a 4' wide overhang on all four sides. The brick exterior wythe extends to just above the soffit of the overhang. Above the brick appears to be a sheet of fiberboard insulation and no vapor barrier. There is haft insulation on top of the acoustical tile ceiling. 2. The roof eaves are level all around the building. The framing at the center of the building has a very slight rise resulting in a maximum roof slope of 1 /2" per foot or less which decreases to zero at the ends of the building which results in the deck being completely level at the ends. The resulting level deck does not drain. Manufacturers' minimum slope for a standing seam metal roof by current standards is 1 /2" per foot. The present flat roof does not meet minimum slope requirements. The roof deck needs to be replaced and the slope adjusted for proper drainage or overlain with additional insulation and a lightweight membrane roofing material such as TPO or EPDM, with proper slope, if the roof structure can support the additional weight. Additional roof insulation can be added with either system. 3. The gutters and downspouts are clogged with debris from the trees overhanging the roof. They need to be cleaned, repaired and the adjacenttrees trimmed or removed. 4. The surrounding landscape seems to indicate that the building was wholly or at least partially constructed on fill materiaijudging by the height of the floor level above the street. As a result, there is some settlement of the floor slab and exterior wall cracking on the southwest long side of the building. Patch the brick cracks to prevent water and insect intrusion or use screw piling to underpin
