5NEW ENTRY AND RAMP FOUNDATION PLANSCALE: 12" = 1'-0"1S01. See General Notes on this sheet for soils conditions.2. Coordinate all dimensions, elevations and openings with Architectural drawings.3. Footings to bear on undisturbed soils centered under bearing elements (U.N.O.) and set minimum 48" below finished grade.4. Footings to be exact size as shown.GENERAL STRUCTURAL NOTES:DESIGN LIVE LOADS: 2009 I.B.C. and Commonwealth of Massachusetts, 8th Edition Amendments* SnowPg = 40 psf* Live100 psf* Wind90 mph, exposure C, 3-Sec gust* I = 1.0FOUNDATION:* Foundation are designed without an engineer's soil investigation. Foundation design criteria was assumed for purposes offoundation design and shall be confirmed by a soils engineer, at owner's expense, prior to construction. (This procedure mayrequire revisions to foundation design, at additional expense to the owner, if soils engineer determines that such design criteriaare inappropriate for this building 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 = .5 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).

Oil forms prior to placing reinforcement.* Do not use Calcium Chloride in any add mixtures with reinforced concrete.* Appearance of finished concrete shall be approved by the Architect.WOOD FRAMING:* Dimension lumber is designed and shall be supplied using Jacob Smith Engineering and Design values design criteria.* General Framing: Spruce Pine Fir #1/#2 and better (Maximum Moisture Content 19%) U.N.O.* Pressure Treated (P.T.): Southern Pine No. 1 Grade or better.1RWH ³3UHVVXUH7UHDWHG/XPEHU´VKDOOEHIUDPLQJPDWHULDORIWKHVSHFLILHGVSHFLHVZKLFKKDVEHHQSUHVVXUHWUHDWHGZLWKGHFD\and insect resistant solution, meeting all current standards for wood in contact with concrete or earth.Sill plates in contact with masonry or concrete foundations, footings or slabs may be treated Timber Strand LSL (zinc boratetreatment). Sodium borate treatment may also be acceptable for sill plate applications when protected from weather.Acceptable treatment mediums for wood in contact with earth or in exterior applications include ACQ-C and ACQ-D (AlkalineCopper Quaternary) and copper azole (CBA-A and CBA-B). DO NOT USE WOODS WHICH HAVE BEEN TREATEDWITH AMMONIA BASED CARRIERS. All connectors shall meet the recommendations of the pressure treated woodmanufactures, but shall be not less than Hot Dipped Galvanized meeting requirements of ASTM A653, such as SimpsonZMAX. (G185). All screws, nails and bolts shall match hangers and other connectors, and shall meet ASTM A123 forindividual connectors, and ASTM A153 for fasteners.For durability, it is our recommendation that connectors used in exposed conditions with treated limber be stainless steel.Do not mix galvanized and stainless products.Do not allow aluminum to contact treated wood.*Roof Sheathing: minimum 12" thick DOC PS-1 plywood, APA 3216 nailed.* Nailing per shall comply with IBC Table 2304.9.1 except where more or larger nailing shown on drawings.* All roof rafters, joists, beams shall be anchored to supports with metal framing anchors.* Cross bridge all dimensional lumber roof and floor joists at midspan and provide solid blocking or rim joists at all joistsupports and joist ends.* Solid blocking between trusses at bearings.* Metal connectors: Simpson Strong Ties unless otherwise noted, install with number and type of nails to achieve maximumrated capacity. Note that heavy duty and skewed hangers may require special order.* All beams shall be braced against rotation at points of bearing.* Unless otherwise indicated, install two lengths of solid blocking x joist depth x 12 inches long in floor framing under columnloads. Columns must have a continuous load path to foundation.* Lead holes for lag bolts shall be 60% to 70% of lag shank diameter in compliance with AITC criteria.STRUCTURAL ERECTION AND BRACING REQUIREMENTS.* The structural drawings illustrate the completed structure with all elements in their final positions, properly supported andbraced. The contractor, in the proper sequence, shall provide proper shoring and bracing as may be required to achieve the finalcompleted structure.* Observations of foundation reinforcing or steel framing required by the owner, lender, building department or any other partywill be accomplished by the engineer at the owner's expense. At least 24 hours advance notice is requested.* Fabricator and / or supplier of roof trusses shall submit shop and erection drawings for architectural and engineering review.Submit two prints for each drawing. Allow ten working days for review. No materials shall be fabricated until shop drawingsare approved.
