Refer to the for information to include on the Traffic Control Plan Sheets.

Traffic Control Plan (TCP) sheets, appropriate for the complexity of the project, provide direction to the contractor and construction staff on the required configuration of TCP measures to move traffic through or around the construction work zone in a safe, expeditious, and clear manner. TCP sheets provide a plan for using traffic control devices to protect the traveling public, work forces, pedestrians, and construction equipment from accidents.

When practical, TCP Standard Sheets developed by the Divisions or Districts should be used. Each work zone is different and the existing standard sheets may not cover all situations. In these cases, the standard plan sheets can be used as a starting point from which the traffic control plan can be developed and tailored to the project’s needs. If the existing standard sheet is not used, the TCP sheet must be signed, sealed and dated accordingly.

The Conflict Layout Sheets, if used, provide information for conflicts that are not certified to be cleared before letting. This can include, but is not limited to, State-Owned or Non-State-Owned utility conflicts, ROW conflicts, ROW encroachments, ROW relocations, Environmental Conflicts, etc. It should be evident from the layouts the location of conflicts and type of conflict relative to proposed and temporary work.

The TCP Narrative describes the sequence of work to be performed as shown in subsequent TCP sheets. The sequence of phased construction should be described in detail if the proposed work causes complicated traffic movements or construction procedures within the project limits. Phased construction is broken out into phases and steps (e.g., Phase 1 – Step 2, Phase 3 - Step 1, etc.).

TCP Typical Sections of different construction phases are included in the plans to illustrate the TCP Narrative sheets. The typical sections are helpful in detailing the width of work zones and the method of traffic handling. Explanatory narrative can be included on these sheets, in the General Notes (under Item 502), or in a triple-zero Special Provision.

TCP Layouts, if used to provide additional information, should be divided by construction phase. TCP Layouts identify where construction is occurring in each phase/step and what measures are in place to safely handle traffic in the vicinity of the construction work. It should be evident from the layouts what arrangement of construction signs, pavement markings, work zone pavement markings, traffic control devices, lane widths, etc., are needed to control traffic at all locations in every phase of work. The TCP Layouts reflect the projects’ construction staging including taper lengths and locations of traffic shifts (include STA and offset for constructability review).

Miscellaneous TCP layouts and details are included in the plan set to depict items such as temporary ramp details, temporary retaining wall/shoring details, detours, etc. Refer to District go-by plans for example miscellaneous TCP plan sheets and details.

Work zone traffic control standard plan sheets are available on TxDOT’s .

Refer to the for information to include on the Roadway Plan Sheets.

The Horizontal and Vertical Control Sheet must be signed and sealed by the registered professional land surveyor (RPLS) directly responsible for the surveying. Control point location maps should be drawn to scale and provide sufficient information so that the point can be located.

Removal Layouts are typically included on major reconstruction projects when the ROW is cluttered with many existing features. The sheets consist of roadway plan views showing the items and call-outs for contractor removal, such as structures, pavements, guard rails, and other existing appurtenances.

Alignment Data Sheets must be provided for all 3R & 4R projects

. 3R projects that do not involve substantial alignment changes (< 10% of the total project length) can use data from previously completed plans to evaluate criteria.

The purpose of the Plan and Profile (P&P) Layouts is to show the horizontal and vertical alignments and may describe other work to be done. These sheets also show existing roadway and utility features which are typically obtained by survey and/or aerial photography.

The plan and profile views are normally shown on the same sheet but may be shown on separate sheets where plan views take up a great deal of space and it would be impractical to show the profile view on the same sheet. shows the recommended scales used for P&P Layouts.

A Crash Cushion Summary Sheet should be included if any new attenuators are proposed in the project. At least

two

(2) attenuator systems must be included for each description type specified for use on the project (from different producers) unless a specific location dictates that only one system is available meeting the size and functionality requirements. The decision to specify one attenuator system must be documented in the project files.

Information describing the attenuator’s details (i.e., direction of traffic, design speed, foundation, backup support, backup width, and/or transition options) is required at each location.

Refer to TxDOT’s for more details and more information on the types of crash cushions available for use.

For larger projects, some of the information which might normally be located on P&P Layouts can be located on other plan sheets such as the roadway and bridge layout sheets to improve clarity and completeness.

Miscellaneous detail sheets may be prepared for items such as curb types, traffic barrier modifications, sidewalk details, curb ramp details, etc.

When storm drain and inlets are part of the proposed project, plan and profile layouts should be developed to indicate the location, type and construction of the appurtenances.

Include Miscellaneous Drainage Details for items such as:

These include standards such as for single and multiple box culverts, wingwalls, headwalls for pipe culverts, safety end treatments, etc. Drainage standard sheets can be found on TxDOT’s .

Refer to the for information to include on the Utility Plan Sheets.

Existing utilities (if available) should be included in the plan set and are

required on the bridge layout sheets

. Existing utilities should also be shown on the proposed utility layouts for joint bid work but can be provided separately if the sheets are too crowded. Utilities that will not clear prior to the start of construction are to be shown on a Utility Conflict plan sheet (to match the Construction Management Plan SOP – See )

Proposed utility layouts must be provided for joint bid utilities when the work is to be done by the contractor as part of the construction contract. The proposed utility layout sheets should be signed, sealed and dated if provided.

Include utility standards if applicable.

Refer to the for information to include on the Bridge Plan Sheets. For detailed information on structural detailing refer to TxDOT’s .

Every bridge and bridge class culvert throughout the nation is assigned a PSN. The PSN is comprised of the following:

PSNs must be unique to each structure; they cannot be changed after a bridge is added to the inventory, nor can they be reused when a bridge is replaced. Bridges that are being widened or rehabilitated retain their PSNs.

Refer to TxDOT’s for more information on obtaining a new PSN for on-system and off-system bridges.

Each bridge and bridge class culvert should have its own Bridge Hydraulic Data Sheet to convey delineated drainage areas, floodplain cross sections used in hydraulic modeling, run-off calculations used, and other elements to document the hydrology and hydraulic design for these structures.

Refer to TxDOT’s for information on drainage design for bridges and bridge class culverts.

Each bridge and bridge class culvert to be constructed or widened should have its own Bridge Layout which clearly illustrates the proposed work and the location of any boring logs. Preliminary and Final Bridge Layouts have plan and profile views drawn at the same scale (horizontally and vertically) of:

Boring logs can be shown on the bridge layout or on separate sheets as indicated in TxDOT’s .

Refer to TxDOT’s for other specific requirements for bridge and bridge class culvert layout sheets.

The Bridge E&Q sheet is a summary of the bid items for all bridges, also including PSN identification and bearing seat elevations (if applicable for the bridge type).

Structural details sheets cover all the details and plan sheets that convey the construction of bridge superstructure elements (i.e., rail, slab, and girders), and substructure elements (i.e., bent caps, columns, and foundations).

These include standards such as for miscellaneous standards, bridge rail standards, prestressed concrete beams, steel beams, etc. Bridge standard sheets can be found on TxDOT’s .

Bridges that require a United States Coast Guard (USCG) Bridge Permit must adhere to bridge permit requirements outlined in the USCG Bridge Permit Application Guide. The Environmental Affairs Division (ENV) has put together the TxDOT.gov that designers should reference for all applicable information needed to assemble plans in accordance with USCG requirements.

Refer to the for information to include on the Traffic Plan Sheets.

Refer to the for information to include on the Railroad Plan Sheets

TxDOT's Traffic Safety (TRF), Bridge (BRG), Rail (RRD), and Construction (CST) Divisions, along with the Class 1 railroad companies, have developed Railroad Requirements General Note sheets that are required by the railroad companies to be included as part of both:

These sheets assist in ensuring that all bidding contractors will be made aware of UP Railroad (UPRR), BNSF Railroad, & KCS Railroad requirements. Although these sheets were developed with the Class 1 railroads, they are also required on projects with shortline railroads due to the generic requirements shown when working on railroad ROWs.

There are two versions of the Railroad Requirements sheets shown on the TxDOT.gov for:

Both versions contain generic, non-project specific information such as Right of Entry, insurance, safety certification requirements, etc. For Bridge Construction Projects, demolition guidelines, construction window constraints, and railroad submittal requirements information are also included.

Sheet 1 of the is to be modified by the designer for project specific details (rail survey and fencing) and signed, sealed, and dated. All other sheets (Bridge Construction and Non-Bridge Construction Projects) do not require a P.E. seal

Additional information for specific railroad lines can be found on the TxDOT.gov .

The identifies project specific work and requirements. It describes the scope of work at the crossing location(s), other project work in railroad ROW, the flagging requirements, any construction work to be performed by the railroad, the railroad insurance requirements, the right of entry agreement, any railroad coordination meeting requirements, and the emergency contact information. Railroad Scope of Work sheets must be initialed and dated per RRD review.

Additional information and a copy of the Railroad Scope of Work sheet can be found on the TxDOT.gov .

If railroad work is included in the project, necessary plans may include plan and profile of new track, grade crossing layouts (planking, signal location, delineation of TxDOT/RR work responsibilities), track typical section, and track details, etc. If a bridge overpass or underpass is included, a railroad Bridge Layout Sheet would be included with other project bridge layouts, if any.

Refer to TxDOT’s for specific requirements for railroad bridge layout sheets. Also refer to TxDOT’s for additional information concerning railroad plans and the Exhibit A.

Refer to the for information to include on the Environmental Plan Sheets.

The EPIC sheet is a summary of all the environmental requirements the Contractor must meet during the life of the construction activities. The EPIC sheet must be completed by the District and list all environmental permits, issues, commitments, conditional requirements affecting the contractor and their work on that specific project. The

EPIC sheet is a communication tool to the contractor and should not include EPICs that are for TxDOT to resolve

- language on the EPIC sheet must be clear and actionable to the Contractor.

The EPIC sheet can be supplemented by specific details shown on other plan sheets, but the areas of concern should be called out on the EPIC for the Contractor’s information. Include everything from conditional requirements from resource agencies to environmental commitments made to landowners and other entities (e.g., tree preservation) on the EPIC sheets.

Late changes to commitments that affect contractor work requirements are to be included in the PS&E by an addendum (see ). Changes in commitments after letting will require either a written notice to the Contractor (e.g., for identifying a restricted area) or a change order for added or reduced work.

Refer to EPIC Standard Sheet on the for a template of the EPIC sheet and the EPIC sheet Guidance document for detailed information on completing the EPIC sheet.

The SWP3 outlines erosion control, sediment control and behavioral best management practices (BMPs) to prevent or minimize sediment and other pollutants originating from construction sites from reaching surface waters of the state during those construction activities. Pollutants can enter waters of the state through direct discharges to water bodies or municipal separate storm sewer systems or can be carried in stormwater as it flows over a construction site. Refer to the TxDOT.gov for more information on the SWP3 requirements including the SWP3 Summary Sheet and required contents of the Environmental Layout sheets.

SWP3 requirements apply to both Construction and Maintenance projects

disturbing 1 acre or more of soil

that meet the definition of a construction activity per the Texas Pollutant Discharge Elimination System Construction General Permit (TXR150000) (CGP), and for projects that disturb less than one acre of soil but have Environmental Permits, Issues, and Commitments (EPICs) dependent on stormwater quality controls and water quality measures (such as US Army Corps of Engineers permits and Best Management Practices (BMPs) for aquatic species). More information about these requirements in discussed in Section 1 of the TxDOT.gov .

For jobs which disturb no soil (seal coats, overlays, etc.), a will serve as the SWP3 and the SWP3 Summary Sheet is not required for the plans. An environmental layout sheet may still be required if there are other resource areas that have information that needs to be conveyed on a layout sheet and described in the next sections.

Refer to TxDOT’s for more information on how to fill out the SWP3 Summary Sheet and the for templates to be used in the plans.

Water resources include rivers, streams, wetlands, lakes, coastal areas, aquifers, and a wide variety of other similar aquatic features. Many water resources are regulated by both the state and federal government and require identification in the plans.

Refer to the for more discussion on water resources requirements for project development.

Biological resources include species listed as threatened or endangered by the U.S Fish and Wildlife Services (USFWS) or the Texas Parks and Wildlife Department (TWPD). Biological resources also include species of greatest conservation need (SGCNs) listed by TPWD. Each SGCN has BMPs and different forms of mitigation and avoidance measures. The engineer will need to coordinate with the District environmental staff and in some cases the ENV SME to determine the appropriate measures to incorporate into the plans. Use “wildlife friendly” erosion control products from the Erosion Control Approved Products List when project BMPs require these products to be used, especially when near sensitive habitats. Include in the General Notes notation of any work time restrictions related to biological resources (e.g. migratory bird nesting season, prairie chicken work restrictions, etc.)

Refer to the for more discussion on biological resources requirements for project development.

The wildlife crossing structure plan will consist of the detail design of each wildlife crossing, wildlife guard, fencing, exits/ramps, and gate requirements for the wildlife crossing structures on the proposed project. Additionally, reference the wildlife crossing structure plan on the EPIC sheet.

Historical resources can be impacted during project construction if not carefully considered during the preliminary engineering phase of project development. Projects with the most potential to impact historic resources include sidewalk projects, projects with culvert work, and projects in historic downtown areas. Historic resources need to be clearly shown on the plans and include appropriate protection notes in the General Notes and on the plan sheets. Special specifications and special provisions can also be implemented to address historic resources.

Protected archeological resources need to be captured in the plans to avoid unpermitted impacts to them. In general, no ground-disturbing activities can occur within the areas of these sites, unless the plans explicitly note an acceptable depth of construction impacts in the site area. Some sites will be buried sufficiently deep that typical construction impacts will not affect them. Depth of excavation needs to be discussed with District environmental staff as part of the environmental clearance process and include a note in the plans indicating the acceptable depth of impacts in the site area.

During the environmental review for a project a noise study may occur. This study might occur during preliminary engineering or early final design phase. Based on the study, noise abatement for traffic noise impacts may be proposed if reasonable and feasible. Noise abatement locations need to be refined during the final design phase of project development. Design staff should assist environmental staff with performing a constructability assessment on the proposed noise abatement and provide design information for noise workshops with affected property owners.

Engineers should be in communication with environmental staff and be aware if noise abatement is being considered. Refer to the TxDOT study “ ” for additional detail.

Approval of walls (and subsequent incorporation into preliminary plan sets) will not be known until after the noise workshop is held. This workshop should be held when enough information is available to present a plan to adjacent property owners and residents. This may be during later phases of final design. This means that changes to the plans could occur as late as the Final (90%/95%) milestone based on the results of the noise workshop

See for more information on Retaining/Sound Walls.

Due to the nature and location of TxDOT projects, there is potential for encountering hazardous materials and wastes before and during construction. Hazardous materials and wastes can be found in existing, adjacent, and proposed ROW. Studies are conducted during the project planning phases to identify potentially hazardous material sources and locations.

Refer to the for more information on hazardous materials.

Human environment impacts evaluated during the environmental phase of the project come in different forms. Some may require specific considerations during PS&E, and others are incorporated into other TxDOT processes, such as public involvement.

The following is a general list of elements impacting the human environment:

There is no one location to address human environment impacts in the plans. Depending on the issue or concern the appropriate solution might fall in the sequencing of construction, additional design considerations (like sound walls), additional outreach during public involvement, or restrictions on the type of equipment that can be used. Information might need to be documented in the General Notes, plan sheets, EPIC sheet, pay items, or a combination of PS&E elements to ensure the Contractor is adequately aware of the commitments made to the public.

Environmental standards such as rock filter dams, sediment control fence, construction exits, erosion control logs, etc. can be found on the .

Refer to the for information to include on the Miscellaneous Plan Sheets.

Landscape and irrigation sheets include appropriate layouts and details if such aesthetics treatments are included in the project.

Refer to TxDOT’s for more information.
