Exhibit F <br /> BNSF Bridge Requirements <br /> BRIDGE DESIGN, PLANS & SPECIFICATIONS: <br /> Except for the design of temporary falsework and shoring, BNSF review of the Structure plans <br /> will be limited to the vertical and horizontal clearances, sight distance for existing train signals, <br /> foundation dimensions and drainage characteristics as they relate to existing and future tracks. <br /> BNSF will not review structural design calculations for the permanent Structure unless a member <br /> or members are influenced by railroad live loads. <br /> Temporary falsework and shoring plans and calculations must be reviewed and approved by <br /> BNSF prior to beginning construction. The Agency shall perform an independent review of the <br /> design calculations for temporary falsework and shoring prior to submitting them to BNSF for <br /> approval. Temporary construction clearances must be no less than 15 feet measured horizontally <br /> from the centerline of the nearest track and 21 feet-6 inches measured vertically from the top of <br /> rail of the most elevated track to the bottom of lowest temporary falsework member. State <br /> regulatory agencies may have more restrictive requirements for temporary railroad clearances. <br /> For the permanent Structure, the Agency will submit plans showing the least horizontal distance <br /> from the centerline of existing and future tracks to the face of the nearest member of the <br /> proposed Structure. The location of the least horizontal distance must be accurately described <br /> such that BNSF can determine where it will occur in both the horizontal and vertical plane. If <br /> the permanent member is within 25 feet of the nearest track(or future track), collision walls shall <br /> be incorporated into the permanent Structure design according to American Railway Engineering <br /> and Maintenance Association Manual of Recommended Practice-Chapter 8 -Article 2.1.5. <br /> For the permanent Structure, the Agency will submit plans showing the least vertical clearance <br /> from top of the most elevated rail of existing and future tracks to the lowest point of the proposed <br /> Structure. A profile of the existing top of rail elevation shall be plotted on the bridge plans. The <br /> profile shall extend for 500 feet in each direction of the proposed overpass and a separate profile <br /> shall be plotted for each track. If the existing top of rail profile(s) is not uniform such that a sag <br /> exists in the vicinity of the proposed Structure, the permanent Structure vertical clearance shall <br /> be increased sufficiently to accommodate a raise in the track profile to remove the sag. Prior to <br /> beginning construction of the permanent Structure, the top of rail elevations should be checked <br /> and verified that they have not changed from the assumed elevations utilized for the design of the <br /> bridge. <br /> Prior to issuing any invitation to bid on construction of the Structure, the Agency should <br /> conduct a pre-bid meeting where prospective Providers have the opportunity to communicate <br /> with BNSF personnel regarding site specific train speeds, train density, and general safety <br /> requirements for men and equipment working near live tracks. Any invitation to bid and <br /> 57 of 60 <br />
