Requirements, Guidelines and Tools

Additional Guidance  

When is a POR seal needed?

Specific work products that require a POR seal are determined by the Department of Transportation's Chief Engineer. These directives include the following:

  • TSB11-01(D) - Professional Sealing of Project Special Provisions
  • TSB11-02(D) - Documents Requiring the Seal of Licensed Engineers, Land Surveyors, Geologists, Landscape Architects and Photogrammetrists.

Applicable statutes, rules and policies

The following apply to work performed for ODOT by licensed engineers, land surveyors, geologists, landscape architects and photogrammetrists.

Oregon Revised Statutes:

Oregon Administrative Rules:

Agency Policy:

The following is an excerpt from this policy.

The Department shall hire and contract for qualified professionals licensed in the state of Oregon to perform work under the responsible charge of licensed professionals in accordance with Oregon statutes, administrative rules and the legal opinions of respective Oregon licensing boards.

Work products required to be sealed by licensed professionals under Oregon statutes, rules, and applicable licensing board rulings/legal opinions shall be prepared by, or under the responsible charge or, qualified professionals.

Each licensed professional who seals a work product shall be the Professional of Record (POR) for the work product bearing the seal. A change or modification to a work product that requires a POR seal must be approved by the POR or an authorized licensed professional who will be responsible for the change. Changes not requiring approval of a licensed professional are not covered under this policy.

Questions about value engineering should be forwarded to Zach Davis, 503-986-7168.

What is value engineering?

It is the systematic application of recognized techniques by a multi-disciplined ​which:

  • Identifies the function of a product or service;
  • Establishes a worth for that function;
  • Generates alternatives that provide the needed functions and reliability;
  • Select an alternative with the lowest overall cost.

When is a value engineering study advantageous?

While value engineering studies are required for projects of a certain dollar amount, they can be beneficial for lower cost projects that include complex elements such as:

  • Interchanges;
  • Major structures;
  • New alignments;
  • Extensive traffic control;
  • Special processes;
  • Special procedures; or
  • Unusually expensive projects.

Problem-solving procedures

The formal problem-solving procedure used to carry out a value engineering study is composed of eight parts.

  1. Selection -- Value engineering studies are required for any project estimated at $50 million or more, and for bridge projects estimated at $40 million or more.
  2. Investigation -- Investigate the background information, technical input reports, field data, function analysis, and team focus and objectives.
  3. Speculation -- Brainstorming function of design elements: What else will perform the function? Where else may the function be performed? How else may the function be performed?
  4. Evaluation -- List advantages and disadvantages. Establish evaluation criteria. Rate each idea. Select the best alternatives for development.
  5. Development -- Develop alternative concepts. Prepare sketches, calculations, and cost estimates.
  6. Presentation -- Prepare written proposals and oral presentations to share alternatives to decision makers.
  7. Implementation -- The design team evaluates the value engineering recommendation and implements those that are acceptable to them.
  8. Audit -- Performance measure of the recommendations are complied and reported to the Federal Highway Administration.

Questions about constructability reviews should be forwarded to Kent Belleque, 503-986-3536.

Request a Constructability Review

Why conduct a constructability review?

ODOT reviews selected design projects to improve the overall quality and cost effectiveness of a construction project.

Reviewers include ODOT staff and members of the contracting community.

Upcoming Reviews


Background information

What is the difference between the review types?

  • Internal reviews -- Informal reviews will be incorporated into all projects and participation is limited to ODOT staff. This review type will generally be conducted near 30 percent completion.
  • External reviews -- External reviews will include members of the private sector and are more formal that internal reviews. This review type will generally be conducted near the 30 percent completion mark as well.
  • Post-construction reviews -- Depending on the project, post-construction reviews may be optional or required. These reviews focus on lessons to be learned from the project.
