enera otes: 1. Wall thicknesses noted are nominal unless specifically stated otherwise. Maximum tolerance is 1/2". 2. Maximum walf to footing centerline offset is 2". A minimum of 2"of footing is to extend on each side of the waii. 3. Place matching hooks around all wall corners and intersections for each horizontal bar. 4. Horizontal bars may be placed anywhere within the wafl thickness provided 2"minimum cover is provided. 5. Bar laps when required are to be at least 32 diameters for grade 40 bars and 48 diameters for grade 60 bars. 6. Allowable bar placement tolerance is 1/2". Tying is not required if tolerances are met and maintained. 7 Oowels may be driUed and ins#alled after faoting pour unless athennrise noted ��'e+-tical bars may be embedded into footing in place of doweis at the same embedment. Vertical bars ano dow�is e�o not need to align. Dowels may be bent down for safety and covering then bent back before wall placement. 8. Sil!plate sections require at least two anchors with one within 4"to 12"of each end and at all corners and intersections. Walls less than 24"in length require only one anchor. 9. Anchor bolts 1/2"or larger in diameter do not require corrosion protection per IRC section R319.3 exception 1. 10. Anchor bolts may be substituted with 1/2"diameter threaded rod epoxy grouted at same spacing with 7"embed. 11. The presence of form oil on the reinforcing is acceptable for the conditions contained in these drawings. 12. Slope grade 6"rninirnum downward away from foundations within first 10 feet or provide Code adequate swale. 13. Do not backfill until the concrete has reached at least 70 percent of the 28 day concrete strength. Use of adequate shoring is required when the final floor and slab systems are not in place. Cald Weather Guidelines: The following information is considered to be general guidelines for the placement of concrete in cold weather conditions. It is the contractor's responsibility to ensure proper means and methods are followed and that the final in place product is adequate. 1. The contractor is to work with the concrete supplier to obtain a mix design which accounts for the conditions expected. Use of extra cement, early-strength concrete, and acceterators are recommended at temperatures below 20 degrees F. 2. Concrete is to be delivered to the site in a timely manner. 3. Placement of concrete earlier in the day to take advantage of latent heat of sunlight is adviced. 4. Do not add additional water. Using�rvater-reducing admixtures is recomrnended when required. 5. Forms are to be free of snow and ice. Do not place concrete in contact with frozen ground ,snow, or ice. 6. Preheating of rebar is not required, however it is to be free of frost,snaw,and ice. 7. Use of form blankets or other approved protection is highly recommended for the top of the wall at temperatures below 10 degrees F and for the whole wall when below zero de rees F.
