• 1 Exhibit F BNSF Bridge Requirements BRIDGE DESIGN,PLANS&SPECIFICATIONS: Except for the design of temporary falsework and shoring,BNSF review of the Structure plans will be limited to the vertical and horizontal clearances, sight distance for existing train signals, foundation dimensions and drainage characteristics as they relate to existing and future tracks.BNSF will not review structural•- 1l calculations for the permanent Structure unless a member or members are influenced by railroad live loads Temporary falsework and shoring plans and calculations must be 4f-wed an'i rprov-.1 ,,.

During construction, BNSF may require an independent engineering inspector to be present during certain critical activities of the Project, including but not limited to: driving foundation piles, erecting falseworlc, construction of shoring and retaining walls, placing concrete, placing soil backfill and compaction processes. The Agency shall reimburse BNSF for all costs of supplemental inspection services. Within 90 days of the conclusion of the Project and final acceptance by BNSF,the Agency will provide BNSF with a complete electronic set of the bridge plans labeled"As Built'.Those plans will reflect any and all deviations from Form 0105 Rev. 06/01/05 47
