Section 6: PS&E Design

Confirming PS&E Design Matches Exhibit A Design

On construction projects, the Exhibit A design is a 30% design completed 12 or more months in advance of the final PS&E. Most railroad companies will request a review and approval of the PS&E (often referred to as an Exhibit B on construction projects) to verify certain elements of the design have not changed. Key elements that should not differ between the Exhibit A and 100% PS&E include:

PS&E Requirements

As part of the PS&E plan set on TxDOT construction projects, the following railroad specific plan sheets are required:

These sheets should be identified in the Index of Sheets under the section heading ‘Railroad’. Do not include the Exhibit A in the PS&E unless there is information which is not contained in the rest of the PS&E such as track realignments.

The Railroad Scope of Work Sheet is intended to clarify project specifics such as:

    Anchor: #XPMSTTHN
  • General railroad information such as DOT number, railroad company, railroad milepost, railroad subdivision and train movements.
    • Anchor: #MPQIPVLC
  • Any work to be performed within railroad right of way identified as work to be performed by TxDOT contractors and work to be performed by railroad companies.
    • Anchor: #UGNYUGIQ
  • Railroad flagging information.
    • Anchor: #FHVLBKQN
  • Railroad insurance requirements for TxDOT contractors and subcontractors including percentage of contract work within railroad right of way (needed to obtain railroad protective liability insurance).
    • Anchor: #NDWJNYUY
  • Whether a railroad Right of Entry Agreement is required and responsible party to obtain (TxDOT on behalf of contractor or contractor).
    • Anchor: #PQPHYDMA
  • Whether a railroad coordination meeting is required as part of the preconstruction meeting.
    • Anchor: #XSIHVIHR
  • Emergency contact information at the railroad company.

It is noted that on bridge projects, railroad protective liability insurance minimum limits are $5,000,000 single occurrence and $10,000,000 aggregate. On non-bridge projects, railroad protective liability insurance minimum requirements are $2,000,000 single occurrence and $6,000,000 aggregate. Contact RRD to verify current insurance requirements.

The percentage of work within railroad right of way is determined by dividing project bid items within railroad right of way by total cost of bid items on the project. Project engineering, contingencies, and other costs are not considered.

The Railroad Requirements Sheets clarify various information for contractors, including:

Information on how to complete the Railroad Scope of Work sheet, Railroad Requirements sheets, and approved Right of Entry Agreements may be found on the RRD website.

The district railroad coordinator should assist the project designer to include these sheets in the PS&E prior to letting.

Special Specifications

If track work is involved, special specifications will usually need to be added to the PS&E. Examples include:

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:

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:

Force Account Estimates

A railroad company force account estimate should be added to the estimate for all work on the project provided by the railroad company, assuming this information is received prior to letting. RRD has posted a general guide on the RRD Crossroads site.
