4 Scope of Work: Perform an annual railroad bridge inspection to identify deficiencies as well as the overall environment of the railroad bridge, following FRA Regulations 49 CFR 237. (1) General The Inspector shall perform a detailed physical inspection and rating of the under grade bridges on the East Rail Line from Denver Union Station to Denver International Airport, Northwest rail from Denver Union Station to Westminster and Gold Line from Denver Union Station to Arvada/Wheat Ridge. The Inspector shall furnish all professional, technical, and support services, and provided all equipment and material necessary to perform both the field and office portions of this project. A-Line (East Corridor) is approximately 22.8 miles long that includes 26 railroad bridges and culverts. B-Line (North West Electrified Segment) is approximately 6.2 miles long that includes 8 railroad bridges and culverts. G-Line (Gold Corridor) is approximately 11.2 miles long that includes 12 railroad bridges and culverts. o For further information on bridges per FRA Regulations, specifically 49 CFR section 14 refer to Appendix A. (2) Special Detailed Inspection The Inspector s inspection team whose qualifications have been submitted to and approved by Denver Transit Operators shall perform the Special Detailed Inspection. The Inspector is required to supply all the equipment necessary to perform the inspection and prepare the report. The results of the inspection shall be documented using photographs, sketches, and appropriate commentary. The documentation shall include system-wide indexing of individual components. System-wide indexing of individual components means that there is a unique label for each component, such as G1 or stringer S10. If there is a unique label for each component in the erection diagram found in the plans, then the erection diagram labeling shall be used. If not, then a unique labeling system shall be used and crossreferenced to the erection diagram labeling. The Inspector shall report indications of overload or failure in any part of the bridge. The Inspector shall report indications of overload or failure in any part of the bridge. The Inspector shall observe the general behavior of the bridge during passage of live load, where practical, noting excessive vibrations, deflection, side sway, and movement at pier supports. If a condition jeopardizing safe passage of railroad traffic is discovered, the Inspector shall immediately notify the Engineer of the situation and follow up with a detailed written report. The Inspector shall recommend a remedy to correct the situation.

5 In order to facilitate rating of the structure, sufficient measurements shall be taken from running rail to bridge to determine eccentricity (if any) between track centerline and bridge centerline. Sufficient measurements shall be taken to determine depth of ballast (ballast dead load) for ballasted deck bridges. Two overall photographs of the bridge (one in each direction) shall be taken at track level. Sufficient information shall be provided about any other superimposed dead loads such as passenger platforms, access roads, etc. Information shall be provided whether tracks are curved or tangent, whether cross ties are concrete or timber and whether deck is open or ballasted. Track designations shall be verified with field personnel providing protection. The condition of any ballast retainers shall be noted. Three overall sketches showing plan, elevation and cross section shall be included in the report. Measurements shall be taken and sketches made for all primary steel members supporting active tracks, such as, but not limited to, stringers, floor beams, troughs, girders, truss members, columns and cross girders. Measurements shall be taken to verify cross section information found in the plans and to measure section loss. Sufficient measurements shall be taken in order for the Inspector to load rate the bridge. It shall be made clear whether measurements are remaining section or estimated loss. Cross-sections differing from those indicated on the plans, and undocumented repairs shall be described in detail. Connections for these members shall be inspected in-depth and descriptions shall indicate whether they are pinned, riveted, bolted or welded. The condition of rivet heads shall be noted. The location and length of any cracks shall be noted. The presence of trough or deck weep holes shall be noted. Other active track supporting primary members, such as solid timber decks, concrete slabs, masonry piers, and abutments, and secondary members under active tracks shall be inspected in-depth. Their condition shall be described in detail in the report. Location of structural defects, significant deterioration and/or member section loss shall be noted. Members not supporting an active track shall be inspected as follows: For members supporting inactive mainline tracks, it shall be inspected and rated with the assumption that the track will be made active in the future. For members supporting inactive siding or non-mainline track, it will be given a cursory inspection for safety flag type items. The Inspector shall inspect substructure elements submerged in water to a depth of 3 feet or less by visual inspection and probing. For substructure elements submerged in water greater than 3 feet in depth, the Inspector shall notify Denver Transit Operators for the need of Special Underwater Inspection for each of the substructure portion below 3 feet, which is not included in this Scope of Work. No permanent marks are to be made on the structure. Temporary marks needed to identify or highlight deficiencies for photographs may be made provided they are removed prior to the completion of the inspection. A copy of all plans shall be available for referral at the bridge during the inspection. If a copy of a plan is used for note keeping, the recorded information shall be legible and included in the report. In addition to structural elements of the bridges to be evaluated, the Inspector shall also note the presence of homeless encampments, breached security fencing, damage to vandal screening and presence of debris, which can impede water flow around the substructure

6 elements. All photographs shall be taken with a digital camera. An overall photograph shall be taken of each type of primary member. A photograph shall be taken of each condition evaluated as poor or worse and/or described in the report. Two overall photographs (side views) of the bridge (one in each direction) shall be taken. For more information regarding bridge inspections refer to RAILROAD BRIDGE SAFETY MANAGEMENT PROGRAM in Appendix B of this document. For a better understanding of requirements for bridge inspections refer to 49 CFR 237, specifically Subpart E. Bridge specific inspection procedures will be provided by DTO as an attachment. (3) Rating The Inspector shall rate the members of the bridge based on a Cooper E - loading in accordance with the AREMA Manual for Railway Engineering, with and without fatigue, and for both the as-built and as-inspected conditions. The results of the rating shall be included in the report in tabular form. The rating table shall include columns for: Span Number, Element, Span Length, Full Impact, Normal and Maximum Ratings for Bending, Shear and Axial Tension & Compression, if any, and Fatigue. (4) Non Destructive Testing The Inspector shall conduct dye penetrant testing in tension zones and at connections with category E or E fatigue details. The Inspector shall provide a detailed description and location of cracks and other anomalies found. The Inspector will provide qualifications and credentials of all personnel associated with the testing procedure and interpretation of the results. The interpretation of the results shall be included in the inspection report. (5) Report The Inspector shall prepare a Special Detailed Inspection report of the findings for each structure. The report shall be signed and sealed by the Program Manager and shall include a cover with an elevation photo of the bridge, table of contents, executive summary, bridge location, bridge description, method of investigation, bridge conditions, rating, recommendations, drawings, sketches, plan index and photographs.

The BSMP will be distributed to RTD and Assignee bridge management, maintenance of way, operations personnel, and consultants and contractors working on bridge related projects for use and compliance. RTDC s BSMP was developed to comply with the FRA Final Rule that railroad track owners adopt a bridge safety management program, and complies with the requirements of 49 CFR Part 237, Bridge Safety Standards. Bridge management practice for RTD Light Rail Transit bridges is subject to separate FTA regulation is not included in this BSMP. This document will be revised in the future as new rail lines are taken into service in order to provide additional inventory of bridges and to update other relevant information. Portions of the RTDC Railroad will be operated and maintained by Denver Transit Operators (DTO) under a concessionaire agreement with RTD; RTD may supplement this BSMP on behalf of DTO in the future with additional bridge safety management directives applicable to their jurisdiction SYSTEM DESCRIPTION The RTDC Railroad is currently in various stages of development and construction. Ultimately the Railroad is planned to include Denver Union Station and the East, Gold, North Metro and Northwest Rail Lines. The East Rail Line, Gold Line, and Northwest Rail Line will be operated and maintained by DTO and will begin operation in A. Denver Union Station (DUS) includes six tracks for commuter rail lines and two tracks for Amtrak. Bridges at DUS include those over the underground bus concourse and the 20 th Street Underpass, all of which carry both commuter rail and Amtrak lines. Commuter rail trains at DUS will be operated by DTO, and structure maintenance will be the responsibility of RTD. Amtrak will begin service at DUS in February 2014 and commuter rail operations will begin operations in B. The East Rail Line is a 22.8 mile long route through Denver and Aurora between DUS and Denver International Airport. RTDC Bridge Safety Management Program Page 1 Version 1.1 December 16, 2013

31 C. The Gold Line is 11.2 miles long between DUS and Wheat Ridge. Bridges west of MP have been assigned to the BNSF Railway for inspection, maintenance, repair and replacement. D. The Northwest Rail Line will initially consist of a 6.2 mile segment from DUS to 71 st Avenue and Lowell Blvd. in Westminster. Ultimately the Northwest Rail line is planned to extend to Longmont with a total length of 41 miles; completion schedule for the ultimate configuration is undetermined. E. The North Metro Rail Line is an 18.5 mile long line that runs from DUS to Highway 7 in North Adams County. The alignment will occupy the right of way of a segment of UPRR Boulder Industrial Lead (BIL) from approximately BIL MP 9.0 at 72 nd Avenue in Commerce City to the North Metro end of the line at MP 33.2 north of Highway 7. This initial segment of this line from DUS to 124 th Avenue is under contract and is expected to begin service in F. The Boulder Industrial Lead was purchased by RTD from UPRR in 2009 and runs 33 miles from Brighton Boulevard in Commerce City to the Valmont Power Plant in Boulder. UPRR currently operates one train per week for a single client on the BIL from MP 0.0 to about MP 9.2. There is one bridge on this track segment over the South Platte River at 74 th Avenue, for which responsibility is currently assigned to UPRR. The Boulder Industrial Lead from MP 9.27 to MP 33.2 is currently not in service and the segment from the future North Metro end of the line to MP 33.7 is currently planned to remain out of service RESPONSIBILITY FOR COMPLIANCE (49 CFR 237.3) RTD is the owner of RTDC track and is responsible for compliance with 49 CFR Part 237 Bridge Safety Standards with the exception that RTD may assign responsibility according to the provisions of 49 CFR (b). RTD retains responsibility for Denver Union Station bridges. Responsibility for the Boulder Industrial Lead from MP 0.0 to MP 9.27 is currently assigned to UPRR. Responsibility for the East Rail Line, Gold Line, and Northwest Rail Line initial segment* will be assigned to DTO prior to opening. BNSF will remain responsible for the Golden Subdivision from MP to MP Responsibility for the North Metro Line is currently undetermined. * Box culverts at the Northwest Rail Line with spans over 10 feet, which qualify as bridges per FRA definition, will remain the responsibility of BNSF ROLES OF RTD AND DTO As owner of RTDC bridges, RTD takes responsibility for BSMP documentation, including future revision as the system is expanded, and for coordination with the FRA for BSMP evaluation. RTD will retain or assign responsibility for compliance with the BSMP at portions of the system as noted in the preceding System Description. RTD will provide oversight of Assignee implementation of the BSMP to the extent of reviewing bridge inspection records, maintenance and repair recommendations, and documentation of maintenance and repair completion.

32 oversight will generally be on an advisory basis; however, plans for any repairs or modifications that change a structure s load carrying capacity or configuration that are designed by DTO s railroad bridge engineer shall be provided to RTD for acceptance prior to implementation. DTO will be assigned responsibility for BSMP compliance for bridges on rail lines noted in the System Description, and will comply with BSMP requirements for the bridges on those rail lines. DTO will provide RTD with records for all bridge inspections, maintenance and repair recommendations, and maintenance and repair documentation ROLE OF THE FEDERAL RAILROAD ADMINISTRATION (49 CFR APPENDIX A) FRA inspectors conduct regular evaluations of railroad bridge inspection and management practices. The objective of these evaluations is to document the practices of the evaluated railroad, to disclose any program weaknesses that could affect the safety of the public or railroad employees, and to assure compliance with the terms of the Bridge Safety Standards. If the evaluation discloses problems, FRA seeks a cooperative resolution. If safety is jeopardized by a track owner s failure to resolve a bridge problem, FRA will use appropriate measures, including assessing civil penalties and issuance of emergency orders, to protect the safety of railroad employees and the public ROLE OF THE EMPLOYEE Employees of RTD or Assignee, consultants, and contractors whose work is related to RTDC railroad bridges or the operation of trains over these bridges must comply with the requirements of the Bridge Safety Management Program. Violation of the requirements of 49 CFR 237 upon which the BSMP is based is subject to civil penalties, and falsification of records is subject criminal penalties.
