Section 3: Traffic Control Plan (TCP)

Anchor: #b040019

Construction or Work Phase Requirements

Each work zone should have designated individuals from the contractor and department who are charged with the responsibility of managing work zone safety.

The district responsible person (DRP) will:

  • make routine inspections to determine if project traffic control is in compliance with the plans and specifications and the Texas Manual on Uniform Traffic Control Devices (TMUTCD)
  • document any major changes to the TCP and
  • assist in work zone accident reviews.

In accordance with the contract, the contractor responsible person (CRP) will:

  • function as the representative of the contractor who is responsible for taking or directing corrective action, as soon as possible, of the installation and maintenance deficiencies. The CRP must be accessible by phone and able to respond to emergencies 24 hrs. per day.
  • report traffic control device deficiencies to the DRP
  • assist the DRP in conducting traffic control device inspections
  • report corrections of traffic control device deficiencies to the DRP and
  • make all reasonable efforts to promptly contact the engineer if a critical situation arises that may require a change in traffic control.

The district traffic control coordinator (TCC) will:

  • accompany the DRP on the initial project inspection and
  • perform quarterly inspections accompanied by DRP, if possible.

Phase Change Inspections and Documentation

Perform an inspection of traffic control in the field immediately after:

  • initial traffic control installation
  • traffic alignment changes and
  • implementation of major traffic control phases.

Documentation of these detailed inspections may be made by photograph, video, Traffic Control Devices Inspection Checklist ( Form 599), memorandum, or other media.

Formal Inspections and Procedures

Perform formal inspections of all traffic control devices twice a month at approximately two-week intervals. Conduct at least one of these inspections at night as soon as possible after the initial set-up for projects with overnight traffic control. Provide the CRP the opportunity to accompany department staff on these inspections. Document the compliance and deficiencies on the Traffic Control Devices Inspection Checklist, Form 599. While the “Project,” “Contractor,” “Night,” and “Day” fields may be entered electronically on the form, all other entries must be written on the form while the inspection is conducted at the project site.

After the inspection, inform the contractor of corrective action needed and obtain the CRP’s signature on Form 599. Provide a copy of the signed form to the CRP. On the original Form 599, document the date the contractor completed corrective action for each deficiency and initial the verification section.

Upon completion of Form 599, file the form and related documentation separate from the project files in a folder boldly labeled “DO NOT DISCLOSE - EXCEPTED FROM DISCLOSURE BY 23 USC §409.” Form 599 folders may be separated from the primary project file and maintained at the district or the area office. Destroy copies of the form. Immediately forward requests for copies of the form to OGC with copies of all completed contract forms for the affected contract(s). The department must seek a ruling from the AG’s office on each request for copies of Form 599. Failure to seek an AG ruling may result in required disclosure of information that federal law requires the department to protect as a condition of FHWA funding. Promptly report to the DRP the date and time deficiencies are corrected for inclusion in the report.

TCP Change Documentation

With the exception of contractor proposed changes, the department is responsible for the design of the TCP and approval of any modifications. The contractor is responsible for implementing and maintaining the TCP. Ensure that the contractor is provided a copy of any revisions to the TCP.

Document changes to the traffic control plan shown in the plans prior to or immediately after implementing the changes. Document changes that alter the original TCP or the sign and traffic control design requirements. The documentation requirements for changes in TCP apply generally to project specific TCPs and changes to the requirements of non-project-specific TCP standards. Minor adjustments to meet practical placement requirements in the field do not necessarily require documentation. Place the documented changes to the TCP with the plans or in the contract files, as appropriate, and provide copies to the department inspector and the CRP.

Changes to TCP plans sheets, sketches and marked up copies of plan sheets, are under the direct supervision of an engineer and require signing, sealing and dating. The engineer’s written field instructions for the TCP changes require the engineer’s professional engineer (PE) designation and the date.
