Newmont‐Cripple Creek & Victor Gold Mine <br />Technical Specification No. 00508.DOCX <br />Squaw Gulch VLF <br />Project No.475.0106.006 <br />June 15, 2016 <br /> <br /> <br /> <br />Page 1 <br />SECTION 00508.0 TIMBER WALL FACING <br />1. PART 1: GENERAL <br />1.1. Scope <br />The CONTRACTOR shall be responsible for removal and salvage of existing crib wall timbers, <br />transportation of timbers to new wall location, and installation of the timbers as a wall facing <br />for the MSE wall. Design concepts are provided in the plan documents for timber facing <br />connections, but the CONTRACTOR is responsible for the final connection scheme. <br />1.2. Construction Sequence <br />A. A pre‐construction conference is required before construction begins. At this <br />conference, the CONTRACTOR shall have a plan prepared for the staging/timing of the <br />construction sequences; means, methods, and details showing the connection of the <br />timbers to the MSE facing; details showing timber spiking plan; and product details for <br />all steel, timber and concrete being used. The DESIGN ENGINEER shall approve these <br />details prior to the CONTRACTOR ordering and fabricating any components. <br />B. After the original SH 67 is permanently closed to traffic, remove the existing crib wall, <br />salvaging reusable timbers. During removal operations, the CONTRACTOR shall <br />consider how to reassemble the timbers as shown on the plans. Consider tagging and <br />photographing the existing wall in its current location. <br />1.3. Facing Requirements <br />A. The wall facing shall be composed of timbers salvaged from the existing crib wall on <br />SH 67. <br />a. Prior to placement, the CONTRACTOR shall verify that the timbers used are free of <br />rot, deterioration, and major longitudinal or transverse cracking. <br />b. Longitudinal timbers shall be at least 8 feet long and shall be connected to a <br />minimum of two transverse timber‐facing units. See the plan documents for <br />details. <br />c. Transverse timbers shall be cut from existing historic timbers and shall overhang <br />the longitudinal members a minimum of 4 inches. <br />B. Connections <br />a. Connect longitudinal timbers to the MSE facing in at least four locations per timber. <br />Connections will consist of a galvanized metal strap secured to the MSE facing and <br />to the longitudinal timbers. The ENGINEER shall approve the connection details. <br />b. Transverse timber facing units shall be secured in at least one place with a drive <br />spike to the timber below.
