32C-319 1 VENTURES FIELD ROAD NORTHAMPTON MA_3-S2-GENERAL NOTES AND DETAILSNEW ELEVATED EXTERIOR DECK ASSEMBLY 1 VENTURES FIELD ROAD NORTHAMPTON, MA 01060 JACOB SMITH ENGINEERING AND DESIGN 5TYPICAL ELEVATED DECK FRAME ELEVATIONSCALE: 14" = 1'-0"1S21. See the General Notes on sheet S2.2. New footings depth shall be 4'-0" below final grade. Place upon exiting undisturbed natural soil.Locate new footings centered under existing or new column elements above.GENERAL STRUCTURAL NOTESLive Loads = 40 psf.Snow Load = Pg = 40 psfFOUNDATION:* Foundation are designed without an engineer's soil investigation. Foundation design criteria was assumed for purposes of foundationdesign and shall 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: 3000 psf* Minimum dead load design soil pressure: no minimum 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:Exterior Slabs:F'c = 3000 psi min.F'c = 4000 psi min.Water/Cement ratio = .5 max Water/Cement ratio = .45 maxSlump = 5" maxSlump = 4" 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). &RQFUHWHFRYHURYHUUHLQIRUFHPHQWò´IRUFRQFUHWHSODFHGDJDLQVWIRUPV´IRUFRQFUHWHSODFHGDJDLQVWHDUWK* Keep reinforcement clean and free of dirt, oil, and scale. 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.* Pressure Treated Lumber (P.T.): Southern Pine #1 grade or better (Maximum Moisture Content 19%) U.N.O.1RWH³3UHVVXUH7UHDWHG/XPEHU´VKDOOEHIUDPLQJPDWHULDORIWKHVSHFLILHGVSHFLHVZKLFKKDVEHHQSUHVVXUHWUHDWHGZLWKGHFD\DQGLQVHFWresistant 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 borate treatment).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 (Alkaline CopperQuaternary) and copper azole (CBA-A and CBA-B). DO NOT USE WOODS WHICH HAVE BEEN TREATED WITH AMMONIABASED CARRIERS. All connectors shall meet the recommendations of the pressure treated wood manufactures, but shall be not less thanHot Dipped Galvanized meeting requirements of ASTM A653, such as Simpson ZMAX. (G185). All screws, nails and bolts shall matchhangers and other connectors, and shall meet ASTM A123 for individual 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.* Nailing per shall comply with IBC Table 2304.9.1 except where more or larger nailing shown on drawings.* All wall studs shall be continuous from floor to floor or from floor to roof.* Metal connectors: Simpson Strong Ties unless otherwise noted, install with number and type of nails to achieve maximum rated capacity.Note that heavy duty and skewed hangers may require special order.* All beams shall be braced against rotation at points of bearing.STRUCTURAL ERECTION AND BRACING REQUIREMENTS.* The structural drawings illustrate the completed structure with all elements in their final positions, properly supported and braced. Thecontractor, in the proper sequence, shall provide proper shoring and bracing as may be required to achieve the final completed structure.* These plans have been engineered for construction at one specific building site. Builder assumes ALL responsibility for use of these plansat Any Other building site. Plans shall not be used for construction at any other building site without specific review by the engineer.* Observations of foundation reinforcing or framing required by the owner, lender, building department or any other party will beaccomplished by the engineer at the owner's expense. At least 24 hours advance notice is requested.* Fabricator and / or supplier of structural steel shall submit shop and erection drawings for architectural and engineering review. Submittwo prints for each drawing. Allow ten working days for review. No materials shall be fabricated until shop drawings are approved.NEW ELEVATED DECK ASSEMBLY ELEVATIONSCALE: 14" = 1'-0"2S21.
