July 12, 1994 BKPR Mr. Ryan Schroeder City of Ramsey 15153 Nowthen Blvd. NW Ramsey, MN 55303 RE: EXISTING BUILDING OBSERVATION Future Public Works Facility Ramsey, Minnesota Dear Mr. Schroeder; As requested, we have performed a visual observation of the two buildings presently owned by Minnesota Sawdust and Shavings, Inc. Our observation of the building took place on July 7, 1994. The purpose of our review is to highlight any significant deterioration in the building's condition, as well as comment on the appropriateness of the existing structures for their future use as public works maintenance facilities. Our review consists of a visual site observation of the existing building for signs of obvious deterioration, and does not include any testir~g, survey, or quantitative structural review of existing building documents. At the time of our observation, a Xerox copy of the original plan and elevation for the masonry building was obtained. Dimensions for the original masonry and precast structure were obtained from these plans. The original site of the Minnesota Sawdust and Shavings complex consists of two buildings. The first building reviewed is a masonry structure with a double-T precast roof. The building was originally constructed in 1977 by the firm of Bendeski Concrete. The overall dimensions of the building are 136'-0" long by 90'-0" wide to the outside face of the masonry. The perimeter masonry walls are constructed of 12 inch concrete masonry units erected to a height of 18'-8". The exterior walls are stiffened by 16 inch by 16 inch masonry pilasters spaced 20'-0" on center. The long dimension of the building is oriented north/south, with the east and west walls acting as bearing walls to sup¢ort the precast double-T roof system. A 12 inch wide by 16 inch high bond beam provideS bearing for this double-T roof system that clear spans the interior of the building in the east/west direction. Three large openings in the west wall of the building provide access to the rail spur that occurs on the west side. Two large openings occut' in the north wall of the building to provide truck access. The precast double-T's making up the roof structure are 2'-8" deep, and support the original four-ply built-up roofing system installed in 1977. The original built-up roofing contains a roofing contraction joint running north/south at the center span of the double-T roof. Drainsge is provided by relying on the camber of the precast double-T's. Water is drained to the east and west walls, where it is collected by a 4 x 4 double wood cant, and allowed to drain through three perimeter scuppers. The cant is flashed with galvanized sheetmetal flashing. No mechanical rooftop equipment is presently supported on the precast roof. The only mechanical provisions consist of a small 3 inch plumbing vent at the northeast corner of the building. The clear span precast roof provides a minimum clear height of 16 feet. The existing floor slab is detaited in the original documents aS a 6 inch deep slab on grade. The condition of the existing floor slab appeared to be in relatively good shape, with very little cracking or differential settlement observed. The floor slab does not slope, and no interior drainage has been provided. o75
