Preliminary Structure Design Report
Supplemental Site PlanStep 8- Stage 1 Detailed Design L&D 1403.7
 Maintain a construction clearance of 13 feet [meters] horizontally from the center of tracks and 22 feet [meters] vertically from a point level with the top of rail.
1) Excavation does not encroach upon a 1 ½ horizontal: 1 vertical theoretical slope line starting 1foot 6 inches below top of rail and at 12 feet minimum from centerline of track.
2) Track is on level ground or in a cut section and on stable soil. (see railroad design manual)
1) a protection shield shall be erected over the track to catch falling debris
2) track may be protected by timber mats placed over the track structure (see railroad design manual)
NARRATIVE OF BRIDGE ALTERNATIVESThe Structure Type Study shall include a brief narrative identifying the structure alternatives and their costs. The narrative should provide insight into why the particular proposed structure was chosen. Factors that need to be considered in selecting a structure for a particular site include geometry, economics, maintainability, constructability, right-of-way constraints, disruption to the traveling public, waterway crossing requirements or grade separations requirements, clearances for railway and highway crossings, foundation considerations, historical and environmental concerns, debris and ice flow problems and appearance.
A. A 1” = 100’ [1 to 1000] scale plan of the alignment of the railroad and the highway extended at least 1000 feet each way from the proposed point of intersection, taken from actual surveys.
B. Profile of top of rails of all railroads, extending at least 1000 feet each way from the proposed intersection.
C. Sufficient cross sections along the railroad and highway to determine approximate earthwork limits and encroachment on railroad property.
D. In case a highway underpass type of separation is at all possible, the submitted information should show the line and profile of the nearest or best outlet for drainage.
E. Intersection angle between highway centerline and railroad centerline.
F. Highway stationing and railroad mile post stationing at intersection.
G. Railroad right-of-way lines.
H. Railroad pole lines, signal control boxes, communications relay houses, signal standards and drainage structures.
I. Centerlines of all tracks and location of switch points.
J. Location of buildings or other structures within the railroad right-of-way.
K. Railroad traffic counts including type of movements and speed.
L. Location of all utilities occupying railroad right-of-way and the names of the owners of these utilities.

Standard Railroad General Notes
608 RAILROAD GRADE SEPARATION PROJECTS608.1 CONSTRUCTION CLEARANCEObtain the actual dimensions used in the text of this note from the "Agreement" (a legal document signed by the Director and Railroad). To help limit project construction problems, validate those dimensions with the district railroad coordinator before the note is considered complete. Revise the note to define the agreed upon restraints, including items such as short term clearances, if different than the construction clearances; maximum period of time for restricted clearances; or other project specific controls.
608 RAILROAD GRADE SEPARATION PROJECTSSECTION 600 TYPICAL GENERAL NOTES CONSTRUCTION CLEARANCE: Maintain a construction clearance of * feet horizontally from the center of tracks and * feet [meters] vertically from a point level with the top of the higher rail, and * feet [meters] from the center of tracks, at all times. * The Designer shall fill in the dimensions.
608 RAILROAD GRADE SEPARATION PROJECTS608.2 RAILROAD AERIAL LINESModify the note below to match the specific requirements of the "Agreement" (a legal document signed by the Director and Railroad). Contact the District railroad coordinator to confirm whether the railroad will move, maintain, or re-construction their lines or other cable systems attached to the bridge or whether the note must specify this scope of work as part of the project. RAILROAD AERIAL LINES will be relocated by the Railroad. Use all precautionsnecessary to see that the lines are not disturbed during the construction stage and cooperate with the Railroad in the relocation of these lines. The cost of the relocation will be included in the railroad force account work.
608 RAILROAD GRADE SEPARATION PROJECTS609 UTILITY LINESUtilities shall be coordinated by the District Utility Coordinator. The District utilities coordinator shall be contacted for required notes. If existing utilities contain asbestos, or other hazardous materials, plan notes will be required to define what material, what utility line and where located. Designer shall assure any plan notes added are coordinated with the bid item descriptions to assure the Contractor properly bids the item. The following note should be used only if utilities are involved and as modified by the district utilities coordinator. UTILITY LINES: The Utilitiy(ies) shall bore all expense involved in relocating (installing) the affected utility lines. The Contractor and Utility(ies) are to cooperate by arranging their work in such a manner that inconvenience to either will be held to a minimum.”
608 RAILROAD GRADE SEPARATION PROJECTSConstruction Clearance:Maintain a construction clearance of 12 feet horizontally from the center of tracks and 21 feet vertically from a point level with the top of the higher rail, and 6 feet from the center of tracks, at all times.? How do you paint the beams ?
608 RAILROAD GRADE SEPARATION PROJECTSThe utility shall bear all expense involved in relocating (installing) the affected utility lines. The contractor and utility are to cooperate by arranging their work in such a manner that inconvenience to either will be held to a minimum.
ERECTION PROCEDURE:THE CONTRACTOR SHALL SUBMIT A DETAILED SUPERSTRUCTURE ERECTION PROCEDURE REPORT FOR ERECTING THE SPAN OVER THE RAILROAD TRACKS. AS A MINIMUM THE REPORT SHALL CONTAIN INFORMATION EXPLAINING THE LENGTH OF THE TIME PERIOD NECESSARY TO ERECT EACH BEAM, HOW CONSTRUCTION WILL BE COORDINATED WITH THE TRAIN TRAFFIC, THE SEQUENCE OF PERFORMING ALL WORK LOCATED OVER THE RAILROAD TRACKS, THE CAPACITY OF CRANES, THE LOCATION OF CRANES WITH RESPECT TO THE TRACKS AND THE ESTIMATED LIFTING LOADS. PRIOR TO BEGINNING WORK OVER THE TRACKS, THE ERECTION PROCEDURE REPORT MUST BE APPROVED BY THE CSX DIVISION MANAGER. THE CONTRACTOR SHALL ALLOW FOR 30 CALENDAR DAYS FOR THE CSX RAILROAD REPRESENTATIVE TO REVIEW THE SUBMISSION (859-344-8137 CSX).
AS-BUILT PLANS FOR THE RAILROAD PRIOR TO RECEIVING PAYMENT FOR THE FINAL PROJECT ESTIMATE, THE CONTRACTOR SHALL PROVIDE ASBUILT DRAWINGS TO THE PROJECT ENGINEER FOR SUBMITTAL TO THE ENVOLVED RAILROADS FOR THEIR PERMENANT RECORDS. THE PLANS SHALL CONSIST OF AND INCLUDE THE FOLLOWING:1. MICROSTATION FILES2. SHOW ALL ACTUAL HORIZONTAL AND VERTICAL CLEARANCES3. SHOW ALL ACTUAL FOOTING DEPTHS, LOCATIONS AND DIMENSIONS4. SHOW ALL LOCATIONS OF UTILITIESPAYMENT FOR THIS WORK SHALL BE AT THE CONTRACT LUMP SUM PRICE FOR ASBUILT RAILROAD PLANS
