_ srn <br />GENERAL NOTES <br />t Prior to excavation check the area for underground facilities. <br />7. All reinforcing shall be intermediate grade deformed bars conforming to ASTA1 A615 Grade 40 (40, 000 psi min <br />yield) and shall be provided by the foundation contractor. <br />3. All concrete shall have a minimum ultimate compressive stress of 3, 000 psi @ 28 days. The requirement for the con- <br />crete shall be as given in the ACI "Standard Building Code for Reinforced Concrete", ACI 318, the latest edition. <br />4. Concrete shall be placed against undisturbed soil to the depth indicated on the foundation drawing. The portion <br />above grade shall be formed. If an area is excavated beyond the limits shown, this volume shall be filled with con- <br />crete or formed. After the forms are removed the excess excavation shall be replaced and compacted. <br />5. The tops of piers at the some elevation shall be level with each other within ! inch. Trowel tops of piers smooth for <br />direct steel bearing. <br />6. Anchor buts shall be provided by Micruflect Co. , inc. They shall conform to ASTM A 572 requirements or equivalent <br />The piers ore designed to resist 206 hips of uplift on a single pier Thr max. calculated uplift per pier is L7 <br />=2_- as per EIA ' .tandurd RS 222C The following conditions ore <br />kips Factor of solely is 2`hkips / +'.i kips <br />assumed in the footing design. <br />A. In uplift it is assumed that the base of the pier engages the frustrum of on inverted cone of earth whose sides <br />form an angle of.aP with the vertical. <br />B. The soil 1s cotiF,dered to woigh 100 pcf with a "Normal Soil" bearing capacity to 4,000 psf. <br />C. Concrete is assumed to weigh 150 pcf <br />8 DR•Y PA.CibING PROCEDURES: <br />Mix 2 ports sand, one part cement, <br />and odd just enough water to allow <br />molding o shape by hand. Restrict <br />the water content to a minimum, <br />[This minimizes the pussibility of <br />shrinkage when the mortar, dry - <br />mixed for maximum density and <br />strength, is pocked in place. ) The <br />packing shall be done by hand, ram- <br />ming with bars or calking tools, or <br />a combination thereof. <br />gervv vANcfowq5OL7C-NTfo5=g; i <br />1I t� <br />cENreRcoroleR rarAwreROrPwoe <br />Fo41NDgT1CW PLAID <br />rv1 Deac K.".Om P <br />
