Foundation design criteria was assumed for purposes of foundationdesign could be confirmed by a soils engineer, at owner's expense, prior to construction. (This procedure may require revisions tofoundation design, at additional expense to the owner, if soils engineer determines that such design criteria are inappropriate for thisbuilding site.)* Footings shall be placed on undisturbed natural soil or compacted fill tested and approved by soils engineer.* Maximum design soil pressure: 2500 psfCONCRETE AND REINFORCEMENT:* Concrete shall conform to with the current ACI-301 Standard Specifications of Structural Concrete.Minimum 28 day compressive strength (F'c) and design properties as followsFoundation elements:F'c = 3000 psi min.Water/Cement ratio = .53 maxSlump = 5" maxEntrained Air = 6% max* Deformed reinforcement: New billet steel, ASTM A615 grade 60.* Reinforcement shall be fabricated and placed per ACI Manual of Standard Practice (ACI-315).
