Special Specifications
If track work is involved, special specifications will usually
need to be added to the PS&E. Examples include:
- Ballasted track construction.
- Underpass structure.
- Culverts or drainage pipes under track.
- Contractor prequalification for trackwork.
Any pipes underneath the track must meet Cooper E-80 loading
requirements.
Designers should pay close attention to any track specifications
to confirm the specification correctly identifies if a contractor
is:
- Providing track materials.
- Performing track removal.
- Salvaging track materials.
- Building track panels.
- Performing track installation.
- Performing track tie-ins.
RRD
and the Bridge Division can assist
the districts if special specifications are needed.The following items do not usually require special specifications
since they are provided by the railroad company:
- Crossing surface panels.
- Active warning devices (i.e., gates, cantilevers, and mast flashers).
- Passive warning devices (i.e., crossbuck signs).
