Section 2: Bridge PS&E Review

Anchor: #i1007817

Overview

As of September 2013, the Bridge Division will provide a 30, 60, 90, 95, and/or 100% review of any bridge project at the request of the Districts. A bridge project is defined as any project which includes structural items in the PS&E. Structural items include the 400 Standard Specification Series and the 4000 Special Specification Series. The 400 Items are contained in Part II, Construction Details, Division IV, Structures, of the Standard Specifications for Construction and Maintenance of Highways, Streets and Bridges. The 4000 Items are statewide, district-wide, and project-specific items pertaining to structures not covered in the standard specifications. The Bridge Division review typically takes two weeks from the date of submittal. The submitted PS&E is reviewed by the following branches, as applicable at the given percentage of the PS&E development:

The Bridge Division PS&E submittal process is as follows:

    Anchor: #SDBPLRAT
  1. The district bridge engineer must approve PS&E prior to submission.
  2. Anchor: #FPBKUKPQ
  3. The PS&E is submitted to the Bridge Division PS&E Review Branch for review.
      Anchor: #LLOOWONT
    1. Email the submittal to the lead PS&E Review Engineer.
    2. Anchor: #CDIBABUB
    3. Email Subject: XX%, PS&E, CSJ, County
  4. Anchor: #XCULKKAF
  5. Division review comments are sent to the Districts for their consideration.

The current fiscal year’s PS&E schedule is available on the Bridge Division’s internal Project Development web page. The current fiscal year’s Letting schedule is located on both TxDOT’s external web page and the Bridge Division’s internal Project Development web page.

NOTE: Access to the internal website is available only to TxDOT personnel. If you need assistance accessing these internal documents, please contact the District with which you are working, or the Bridge Division project manager.

It is essential to prepare proper plans, specifications, and estimates (PS&E) in order to prevent delayed letting dates. For information on projects with no bridge bid items, refer to the PS&E Preparation Manual, which contains general requirements for PS&E. Requirements specific to projects containing structural items are provided below to further assist in PS&E preparation.

Plans

For projects with bridge plans, follow these preparation guidelines.

    Anchor: #JKBRLFHT
  • Obtain preliminary bridge layout approval prior to any percent PS&E submittal. Include preliminary retaining wall layouts with this submittal when necessary. See Section 1 of this chapter for more information.
  • Anchor: #DLBGNUJS
  • Include bridge plan sheets prior to submitting final PS&E for review.
  • Anchor: #VIRWDFAG
  • Ensure information on the title sheet corresponds with information on Design and Construction Information System (DCIS).
  • Anchor: #AOLHLLHC
  • Include the most current standards. All standards used must be clearly listed on the index of sheets even if unavailable at the time of submission.
  • Anchor: #PSTBKQSA
  • All modified (MOD) and special (SPL) standards must be signed and sealed by the responsible engineer. Include a brief description of the modifications, typically shown in the Revisions area of the title block.
  • Anchor: #TSDAWABP
  • Show all hydraulic documentation correctly in the final plans as required by the Hydraulic Design Manual. Hydraulic comments based on the preliminary submissions must be addressed prior to submitting final PS&E.
  • Anchor: #QOKEDDER
  • For projects involving a highway-railroad grade separation, an executed railroad agreement is required prior to letting. On federal oversight projects, send a copy of the agreement to the Federal Highway Administration (FHWA). Further information concerning railroad agreements can be found in Chapter 4 of this manual.

Specifications

For projects with bridge specifications, follow these preparation guidelines.

    Anchor: #NLPVHMDH
  • List approved names and addresses of manufacturers of proprietary designs included in a project.
  • Anchor: #LPBAOGLD
  • For projects involving a railroad agreement, it may be necessary to add a fiber optics note when required by the executed railroad agreement. The Traffic Operations Division’s Rail Safety Section will specify the requirement for the fiber optics note during the PS&E review process.
  • Anchor: #DHPDJKWR
  • Special provisions and special specifications must be in Rich Text Format and in the appropriate template. See the following link for templates: http://www.txdot.gov/inside-txdot/division/construction/txdot-specifications.html
  • Anchor: #YXDTSTMT
  • New special specification or special provision. After determining that standard specifications and any approved existing special provisions (SP) or special specifications (SS) do not cover the specific work item required in a bridge project, request a proposed new SS or SP. See the Memo dated July 15, 2015 on the Bridge Division’s internal Project Development web page for more information.

NOTE: Specification Item 6 contains general information on how to handle hazardous materials.

Estimates

Prepare an estimate using the following guidelines and methods described in the Project Development pages of the Bridge Division’s internal website.

All bid items pertaining to each bridge or bridge-class culvert must be broken out and listed separately.

    Anchor: #HJCJWWJJ
  • Estimate items. Show the following items on the estimate:
  • Anchor: #WBGGDVFB
  • Bid items. Cost estimates for bridge work are shown on the DCIS P4 screen. Bridge items, including bridge-class culvert structures, are broken-out separately from roadway items. This break-out arrangement provides information requirements for the reporting of bridge construction cost information to the Federal Highway Administration, Legislature, Commission, Administration and users within the department, and other public agencies.
  • Anchor: #DNVNWOHY
  • New bid codes. A new bid code may be requested if there is no existing bid code that covers the specific work item required in a bridge project. See the memorandum dated July 15, 2015 on Bridge Division’s internal Project Development web page for more information.
  • Anchor: #PMMXEPVX
  • Alternate bid items. Contact the Bridge Division plan review engineer for preparing estimates with alternate bid items.

Final PS&E

The Districts are responsible for the preparation, final review, and submission of the ready-to-let bridge PS&E package. Once the District Engineer has signed and sealed the bridge project, the plans will be submitted to the Design Division to process for letting.

It is imperative to enter information on the BCI screen and P3B screen correctly so that staff can calculate the unit cost data for all bridge projects and to ensure federal reimbursement on any federally participating bridge projects. Section 3 of this chapter provides the information needed to enter this data into DCIS accurately. Please contact the Bridge Division’s PS&E Review Branch if you have any questions.

For bridge projects with Federal Highway Administration (FHWA) oversight, the District will submit the final (100%) PS&E for FHWA’s review a minimum of six weeks prior to letting.

If a bridge project crosses railroad ROW, the District will submit a final (100%) set of railroad approved plans to the Traffic Operations Division a minimum of six weeks prior to letting for inclusion in the Exhibit B set of PS&E in the railroad agreement. Exhibit B railroad agreements are only needed for Railroad Underpass projects. Examples of railroad PS&E and Exhibit B submittals are located on the TxDOT internal website here: http://crossroads/org/TRF/_includes/documents/5-Sample_Exhibit_B.pdf

For assistance accessing these or other internal website documents, please contact the District with which you are working, or the Bridge Division project manager.
