HomeMy WebLinkAboutFoundation Plans 58 Miss Way 2022 Standardized Concrete Foundation Drawings SCOPE OF WORK: These drawings apply to the construction of cast-in-place concrete foundation walls for typical residential cases. These drawings are not to scale and all conditions are to be verified by the contractor. Means and methods of construction for shoring, water-proofing, insulation, flashing, control and construction joints, and all other non-structural requirements are to be by others in accordance with the Code and standard industry practice. These drawings are valid until the end of 2022. The drawings are to only be used by the contractor noted below or his authorized sub-contractors/clients. These drawings are to be provided to the building inspection department as part of the permit package. INDEX: S1 - Scope, Index, and Certification S2-General Notes S3- Step Footing Detail S4- Frost Wall Detail S5- Lookout Wall Detail S6- Full Height Wall Detail MATERIALS: Reinforcing Steel:Grade 40 (40 ksi)for#4 and smaller bars Grade 60 (60 ksi)for#5 bars and larger Rebar Substitution Notes: 1. Two#4's bundled may be used to substitute (1)#6 and vice versa provided they are of the same grade steel. 2. For vertical bars on S6,#5's may be used in lieu of#6's at two-thirds of the noted spacing. Concrete: Mix design is to be prepared by the concrete supplier to meet the project's requirements Minimum 28 day compressive strength of 3000 psi for walls Minimum 28 day compressive strength of 5000 psi for footings Footings may be 3000 psi if an approved admixture is used to achieve a water and vapor resistance equivalent to 5000 psi Backfill Soil: Sand-30 psf/ft effective lateral pressure Sandy Clay (SC)-45 psf/ft effective lateral pressure Clay-60 psf/ft effective lateral pressure hereby certify that this plan,specification,or SITE ADDRESS: report was prepared by me or under my direct supervision and that I am a duly licensed professional engineer under the laws of the state Street: of Minnesota.

Wall thicknesses noted are nominal unless specifically stated otherwise. 2. Maximum wall to footing centerline offset is 2". A minimum of 2"of footing is to extend on each side of the wall. 3. Bar laps when required are to be at least 40 bar diameters for grade 40 and 60 bar diameters for grade 60. 4. Bend horizontal bars or provide matching hooks around all wall corners and intersections. 5. Horizontal bars may be placed anywhere within the wall thickness provided 2"minimum cover is provided. 6. Allowable bar placement tolerance is 1/2". Tying is not required if tolerances are met and maintained. 7. Dowels may be drilled and installed after footing pour unless otherwise noted. Vertical bars may be embedded into footing in place of dowels at the same embedment. Vertical bars and dowels do not need to align. Dowels may be bent down for safety and covering then bent back before wall placement. 8. Sill 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. Sill plates may overhang the face of the wall provided the overhang is not loaded vertically and all anchor bolt/connection tolerances are met. 9. Anchor bolts 1/2"or larger in diameter do not require corrosion protection per IRC section R317.3.1 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"minimum 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 and fully anchored. 14. Maximum inside window well dimension is 72". Well walls are to be at least 8"thick placed monolithically with house walls with horizontal bars extended into them and around corners. Provide two additional vertical bars and one additional anchor bolt each side of opening. Opening header by others. COLD WEATHER GUIDELINES: The following information is 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 accelerators 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 advised. 4. Do not add additional water. Using water-reducing admixtures is recommended 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,snow,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 degrees F.
