Top and bottom plates shall be of Douglas Fir-Larch or Hem-Fir #2 or better. Plates in direct contact with concrete or masonry shall be of pressure treated Hem-Fir #2. Preservative treated lumber requires all connections and nailing be galvanived per code. E. For all solid or built-up columns bearing through floor joist spaces, provide blocking in joist space with cross sectional area to match column above. F. Except as otherwise noted, the minimum nailing shall be provided as specified in the "Nailing Schedules (IBC Table 2304.9.1). G. Bolts used for wood framing connections shall be installed with standard washers and nuts. H. Unless noted otherwise, steel connectors such as those manufactured by the Simpson Company shall be used to join rafters, joists or beams to other beams at flush-framed conditions. Use all specified nails. Connector conditions not otherwise noted shall utilize Type U or Type HU hangers of a size specifically designed for the member supported, as shown in the manufacturer's published tables. Contact structural engineer for details as required. I. Laminated Veneer Lumber (LVL) shall have the following stress properties: x Flexural stress 2800 psi x Modulus of elasticity 2,000,000 psi x Tension parallel to grain 2100 psi x Compression parallel to grain 3000 psi x Compression perpendicular to grain 900 psi x Horizontal shear 285 psi L. For multiple member beam connections, unless noted otherwise in L. For multiple member beam connections, unless noted otherwise in manufacturer's specification, use the following guide: x Strong-axis Loading of Beams (vertical loading): 1. For members 12" deep or less, nail each member to the next with (2)-rows of 12d nails @ 12" o.c. 2. For members greater than 12" deep, nail each member to the next with (3)-rows of 12d nails at 12" o.c. x Weak-axis Loading of Beams (lateral loading): 1. For two or three member beams, nail each member to the next with (3)-rows of 12d nails @ 12" o.c. 2. For four member beams, bolt through with (2)-rows of 1/2" dia. bolts at 12" o.c. M. Framing Notes: x Exterior Walls: a. All exterior walls are 2x6 studs @ 16" o.c. to a maximum height of 12'-6", 2x6 studs @ 12" o.c. to a maximum height of 14'-6", and (2)-2x6 studs @ 16" o.c. to a maximum height of 16"-0" unless otherwise noted. Walls taller than 16'-0" shall be framed with manufactured versa-lam studs, contact engineer for spacing requirements, if not indicated on plans. Cap with a double top plate installed to provide overlapping at corners and at intersections with other partitions. If overlap is not possible, strap top plates together with metal strap ties (Simpson ST292 or equivalent). b. At beam bearing locations in stud walls, provide multiple-studs post equal to width of bearing member unless noted otherwise. x Floor Construction: a. Provide 5/8" thick APA rated Sturdifloor rated @ 16" o.c., tongue and groove, exposure 1. Glue and nail panels with 10d nails @ 6" o.c. along panel edges and @ 12" o.c. at intermediate supports, unless noted otherwise. Install sheathing with long dimension perpendicular to joists and end joints staggered. b. Provide solid blocking for floor joists at each bearing end and at mid span. Blocking material shall match floor joist material and shall be a rim or ledger at the ends and pressure blocking at mid-span. c. Panels shall be identified with the grade-trademark of the American Plywood Association and shall meet the requirements of U.S. product standard PSI, latest edition for plywood. Structural Steel: A. Structural steel shall be detailed, fabricated and erected in accordance with the latest provisions of AISC "Manual of Steel Construction". B. All structural steel rolled shapes, including plates and angles, shall conform to ASTM A36. Tube shapes shall conform to ASTM A500 Grade B. Pipe columns shall conform to ASTM A53. The latest editions of these requirements shall be used. Steel supplier may optionally provide ASTM Grade 50. C. All structural bolts used in steel framing shall be A325-N, installed to a minimum snug nut condition. All anchor bolts shall be of ASTM A307. D. Typical Framed beam connections with steel bolts shall use the maximum number of bolts per AISC "Manual of Steel Construction" Table IIA and/or AISC "Simple Shear Connection Manual" with A325-N bolts. E. All welding shall be performed by an AWS qualified welder. F. Delay painting within 3" of field welds until welds are completed. General Requirements: A. Structural erection and bracing: The structural drawings illustrate the completed structure with all elements in their final positions supported and braced. The contractor, in the proper sequence, shall provide shoring and bracing as may be required during construction to achieve the final completed structure. Contact engineer for consultation as required. B. Existing structures: Where construction adjoins an existing structure, the contractor shall be responsible for verifying dimensions, elevations, framing, foundation and anything else that may affect the work shown on the structural plans. Under pinning, shoring and bracing of the existing structure shall be the sole responsibility of the contractor. C. Dimensions: Check all dimensions against field and architectural drawings prior to construction. Do not scale drawings. D. Construction practices: The general contractor is responsible for means, methods, techniques, sequences and procedures for construction of this project. Notify structural engineer of omissions or conflicts between the working drawings and existing conditions. E. Coordinate requirements for mechanical/electrical/plumbing penetrations through structural elements with structural engineer. Prior to installation of such equipment or other items to be attached to the structure, the contractor shall obtain approval for connections and support. Contractor shall furnish required hangers, connections, etc. required for installation of such items, unless specifically noted on plans. F. Jobsite safety is the sole responsibility of the contractor. G. The structural engineer may make periodic observation visits to the jobsite for determination of general conformance with the construction documents. Such observation visits shall not replace required inspections by the governing authorities or serve as "special inspections" as may be required by Section 17 of the International Building Code. H. Though every effort has been made to provide a complete and clear set of construction documents, discrepancies or omissions may occur. Release of these drawings anticipates cooperation and continued communication between the contractor, architect and engineer to provide the best possible structure. These drawings have been prepared for the use of a qualified contractor experienced in the construction techniques and systems depicted. NO. ISSUE PROJECT: JOB NO. SHEET NO.
