Rails. 10. Radio transmitters, spares and allied equipment
Rails. Assemble joints before fastening rails to ties, using joint bars with full number of track bolts and spring washer for each bolt, first removing loose mill scale and rust from contact surfaces or joint bars and rails. If necessary to force joint bar into position, strike lower edge of bar lightly with 4-lb. maul. Do not drive bolts in place. Tighten bolts in sequence, beginning at joint center and working out to ends. Bolts to be tightened to a range of 20,000 to 30,000 lbs. tension. If a bolt tightening machine is not used, a standard track wrench with a 42" long handle may be used. In laying secondhand rail, care must be taken to rail end mismatch at the joints. Under no circumstances must rail be struck in web with tool or any metal object. The right-hand rail facing in direction of increasing construction shall be spiked to ties, and the opposite rail shall be brought to gage of 4' 8-1/2", measured at right angles between the rails, in a place 5/8" below top of rail. Gage to be checked at every third tie. Rail shall be laid with staggered joints. Joints shall be located as nearly as possible to the middle of the opposite rails with the following variation: (a) except through turnouts, the staggering of the joints on one side shall not vary more than 6' in either direction from the center of the opposite rail. Continuous welded rail (CWR) will need to be de-stressed as soon as possible after laying.
Rails wheels, guide bearings and all drive components shall exhibit no abnormal frictions, abrasion, binding or wear on or between contract surfaces.
Rails. 3.11.1 A track rail running from one side of the pit wheel lathe shed to the other shall be used to enter and exit trains.
Rails. Install rails as shown on drawings. Set rails as nearly parallel to the grade as possible and at the specified height. Gates. Xxxxx shall hang plumb and true, and swing easily either direction with no interference. Use lockable fork latches. REVISION OF SECTION 607 - FENCING Fabric. Fabric to be stretched taught to where there is no movement in the mesh when compressed. Top rail and bottom rail ties shall be 12" on center. Posts ties shall be 12" on center. Basis of Payment: PAY ITEM PAY UNIT Chain Link Fence (10') (Coated) Linear Foot Chain Link Fence (4') (Coated) Linear Foot REVISION OF SECTION 608 - SIDEWALKS AND BIKEWAYS Add the following to Section 608 for Concrete (5") (Post-Tension): Description: The contract work to be performed under this section consists of furnishing all required labor, materials, equipment, implements, parts and supplies necessary for, or appurtenant to, the construction of a 5" thick post-tensioned concrete slab. Work shall be performed by a contractor with a minimum of 6 similar, successfully completed projects within the past 3 years who is a member of the American Sports Builders Association, and has a Certified Tennis Court Builder on staff. Contractor shall be a member of the Post-Tensioning Institute (PTI). Installing xxxxxxx shall be a certified by the Post-Tensioning Institute (PTI) as a Level 1 installer and all work to be supervised by a PTI Certified Level 2 Inspector. To eliminate potential liabilities of construction, the contractor or subcontractor for the post- tension slab shall assure single-source responsibility by completing all work with his own forces, to include fine grading, construction, tendon fabrication and placing, concrete placement and tendon stressing. Contractor shall submit its final design and calculations for review 2 weeks prior to the start of construction of the slab. Contractor shall provide the following documentation:
Rails. 1.1.15 Assembly on Surface
Rails. The crane runway shall consist of jointed flat bottom rail and shall be installed to within +2 mm. of level for its full length. Each section of each crane runway rail shall be interconnected and the rails shall be connected by grounding conductors to the Powerhouse grounding system.
Rails. 1. The selection of rail section and steel grade to be used for high-speed track installation shall be determined from assessment of the axle load in order to provide a rail with acceptable beam strength to support the load on standard ties at the appropriate spacing and a reliability in accordance with the Contract Requirements.
