3. "Recommended Nailing Schedule" of referenced framing standard and with AFPA's <br /> "National Design Specifications for Wood Construction." <br /> 4. "Table 23-I-Q, Nailing Schedule" of the Uniform Building Code. <br /> G. Use common wire nails unless otherwise indicated. Use finishing nails for finish work. Select <br /> fasteners of size that will not fully penetrate members where opposite side will be exposed to <br /> view or will receive finish materials. Make tight connections between members. Install fasteners <br /> without splitting wood; pre-drill as required. <br /> H. Use hot dipped galvanized or stainless steel nails where rough carpentry is exposed to <br /> weather, in contact with the ground or in areas of high relative humidity. <br /> I. Countersink nail heads on exposed carpentry work and fill holes with wood filler. Paint to match <br /> existing trim, fascia, etc. <br /> 3.05 BLOCKING & NAILERS: <br /> A. General: <br /> 1. Installing wood nailers, blocking and sleepers where shown and where required for <br /> screeding or attaching other work. Form to shapes shown and cut as required for true line <br /> and level of attached work. Coordinate locations with other work involved. <br /> 2. Attach to substrates to support or withstand applied loading. Contractor shall consider the <br /> safety factor for the fastener and substrate being attached to. <br /> 3. Recess bolts, washers and nuts flush with surfaces unless otherwise indicated. <br /> 4. Do not install fasteners within 1-'/2" of edge of concrete surfaces to prevent spalling of the <br /> substrate. <br /> 5. Minimum linear uplift resistance of nailers shall be 200 Ibf/ft. <br /> 6. Withdrawal and pull-over resistance of fasteners shall be 100 lbs. minimum. <br /> 7. Install fasteners in a staggered fashion. <br /> 8. Length of fasteners to secure secondary nailers or blocking shall be sufficient to penetrate <br /> preceding blocking by 1- 1/4". <br /> 9. Install nails at an angle. <br /> 10. The fastener length shall be sufficient to penetrate through steel decks a minimum of 1/4" <br /> and 1" depth into concrete substrates. <br /> B. Provide a '/4' gap between each section of wood blocking. Terminate nailers at control joints <br /> and expansion joints. <br /> 1. Before roofing commences, all carpentry such as wood nailers, wood curbs, wood cants <br /> and similar items shall be installed. <br /> C. Fasteners, Spacing & Depth: The fastener type, spacing and depth are provided for general <br /> guidelines only. Contractor shall verify by testing or empirical means that the fasteners <br /> prescribed meet the minimum uplift resistance specified herein. <br /> D. Nailer for Securing Metal Fascia & Gravel Stops: <br /> 1. Stack nailers as shown on drawings. <br /> 2. Wood blocking shall not overhang the deck no more than 2". <br /> 3. Secure nailers to substrate to achieve the minimum uplift resistance. <br /> 4. Discontinue nailer at expansion joints. <br /> 3.06 EQUIPMENT CURBS: <br /> A. Fabricate curbs sturdy to withstand anticipated loads. <br /> B. Locate curb so that it is supported by one or more major purlins or beams. <br /> C. For larger units, contractor shall furnish and install welded metal curbs, designed, and <br /> prescribed by the equipment manufacturer. <br /> D. Curbs shall be a minimum of 8" above the membrane surface and as shown in the details. <br /> E. Secure to substrate with 18 gauge angle brackets and appropriate fasteners, spaced a <br /> minimum of 24" on center. <br /> SEA00511 / Prologis - SEA00511 06 1000 - 5 Rough Carpentry <br /> - FY24- Everett 1 - Capital <br /> Roofing Project <br />
