MoDOT’s three pillars of “Safety, Service and Stability” steer our leadership and employees. Our commitment to safety includes keeping both customers and ourselves safe. Our service includes providing outstanding customer service, delivering transportation solutions of great value and using resources wisely. Keeping roads and bridges in good condition, operating a reliable and convenient transportation system, and advancing Missouri’s economic development reflect our commitment to stability. Innovative concepts, such as Practical Design and design-build, are used to deliver our commitments. These and other forward-thinking concepts shape the content of the ENGINEERING POLICY GUIDE (EPG). This document provides a single reference for all engineering and engineering-related Bridge, Construction, Design, Highway Safety & Traffic, Maintenance, Planning and Right of Way guidance.

Information for Digitally Signing Documents

There are several documents (internal and external) that can be signed with digital signatures through PDF editing software. ONLY PDF DOCUMENTS CAN BE DIGITIALLY SIGNED. First you must set up your digital signature ID: - If you are an Adobe Pro/Reader user, please see the Quick Reference Guide (QRG) Digital signature for Adobe Reader DC or Pro DC to set up your digital signature ID. If you are not including an image of your signature, you can skip Section 1 regarding capturing your signature image; go to Section 2 to set up your Adobe digital signature ID. Unless you work in Construction and Materials, skip Section 3 as well. Page 7 of these instructions will also look a little different due to software updates. The Sign Document window will most likely be Sign With a Digital ID; click on Continue. If you are including an image of your signature you will have to click on Create and follow the steps (also follow the directions in Section 1 for capturing your signature image). Otherwise you will enter your password and click on Sign. - If you are a Bluebeam Revu user, please see Creating Digital IDs in Bluebeam Revu to set up your digital signature ID. The following documents may be signed with the digital signatures methods above: Professional Services Committee (PSC) Letters/Approvals Design Exceptions Letters to external partners Expense Reports. If you are not sure if a document can be digitally signed, please reach out to your Assistant District/Division Engineers for guidance. This information will be updated as needed. Please check back often. Other helpful documents and tips: Digital Signatures for Design Documents - this does not work with most Adobe Reader versions (contributed by Christopher Kelly, TPM in SL District). See E-Construction general provision in the most recent version of the General Provisions and Supplemental Specifications for additional digital signature information (suggested by Christopher Crocker, TPD in SE District). Digitally Signing Preliminary Plans in ProjectWise - this does not work with all versions of Adobe Acrobat Pro/DC (contributed by Don Saiko, TPM/Stacy Reese, ADE in SW District).

The design concepts and criteria within the Engineering Policy Guide (EPG) are intended for use when designing new construction projects on new locations or designing reconstruction projects on existing locations. Projects on existing roadways call for a flexible, practical, and performance-based approach to design. The EPG encourages flexible and practical design, which emphasizes the role of the planning and design teams in determining appropriate design dimensions based on project-specific conditions and existing and future roadway performance, more than on meeting specific nominal design criteria. Although new design values and concepts may be presented throughout the EPG, this does not imply that existing roadways are unsafe, nor does it mandate the initiation of projects to improve existing roadways. While the EPG does include nearly all engineering related aspects of roadway design and maintenance it is not all encompassing. The use of properly equipped and maintained vehicles, operated by a capable user, is also pertinent to the safe and efficient operation of a transportation facility.
