, • �i � TEMPORARY BRACING Contractor is responsible for bracing, without overstressing, all structural elements as required at all stages of construction until completion of this project. Provide temporary lateral support for all walls until walls are adequately braced by permanent structure. Shore foundation walls retaining earth until floor framing and basement slab are in place. Use caution when operating equipment adjacent to foundation walls. GENERAL SOIL NOTES The structure has been designed using a presumptive load-bearing value of 2000 psf in accordance with Table R401.4.1 of the 2006 IRC on virgin soil or compacted granular fill for footings. Remove all top soil, uncompacted fill,or other poor soil from the construction area. Slope the site to drain away from the building. Install gutters and downspouts. Install drain tile. Backfill with granular soils. FOOTINGS/FOUNDATIONS All footings are to be formed. All stumps, roots and debris must be removed from the soil to a depth of at least 12" below the surface of the ground in the area occupied by the building. Footings shall be placed on virgin soil or compacted granular fill. Wall footings are cast-in-place concrete with continuous reinforcing placed 3"clear of bottom and 2"clear at top and sides. Wall footings are centered under walls and column footings under columns. Wall footings shall be a minimum of 10"thick with a 4"projection each side of wall. Reinforce with 2 -#4 continuous bottom bars. Column footings shall be a minimum of 12"thick, with plan dimensions as shown on drawing. Reinforce with#4 bottom bars at 8"o.c. each way. Provide 30 bar diameter lap at splices and full crossing lap at corners and intersections.Tie all reinforcing in place. Set footing reinforcing on chairs or masonry brick to obtain 3"clearance from bottom of footing. Maintain minimum frost depth of 42"for all exterior footings. Top of footing shall be placed below the top of slabs on grade, or placed to maintain frost depth, whichever is deeper. Step footings in a uniform manner using a 2:1 horizontal to vertical slope. Cast dowels in footing for foundation walls above. Dowels shall be the same quantity, size, and spacing as the vertical wall reinforcing. Dowels shall be 30"long and extend to 3"clear of bottom of footing. Contractor shall be responsible for implementing hot weather concrete requirements per ACI 305'and cold weather concrete requirements per ACI 306. Shore all foundation walls appropriately before backfilling and compacfing. Foundations supporting wood shall extend at least 6"above the adjacent finished grade. At foundation end walls,provide perpendicular full-height blocking at 24"o.c. in the first three joist spaces. Glue and nail to joists and subfloor. Attach to sill plate with 2-USP MP5 clips or equal. The contractor shall verify the location of all existing underground utilities and tanks prior to beginning excavation. CONCRETE Provide ready-mixed concrete per ASTM C94. Portland cement shall be ASTM C150,Type I. Use only one brand of cement throughout the work. Provide concrete aggregates meeting the requirements of ASTM C33. Maximum aggregate sjze shall be 3/4"for grade beams and slabs. Water shall be clean,free of deleterious amounts of acids, alkalis,or organic materials, and shall be considered potable. Provide admixtures to reduce water content, provide air-entrainment,or alter the quality of the concrete to meet the job conditions. All wall openings targer than 12"shall have 2-#5 at all sides extending 2'-0"beyond each edge of opening with 2-#5 x 4'-0"diagonal bars at each corner of opening.
