Structures Design and Detailing Manual
Structures Design and Detailing Manual
The UDOT Structures Design and Detailing Manual (SDDM) has been developed to provide the Structures Design staff and consultants with UDOT policies, procedures, practices and technical criteria. The SDDM consists of the written manual, drawings (working standards, structures design drawings, sample sheets), checklists and SDDM Revision Memoranda. The information presented in the SDDM is expected to help fulfill UDOT’s mission of providing a safe and efficient transportation system.
For convenience, the “Current SDDM Written Manual” includes the most recent full release of the written manual along with interim revisions to date in a single document. Please verify that the copy includes the most current interim revisions. Previous published versions of the written manual, drawings, checklists, and SDDM Revision Memoranda are provided below.
Structures Design and Detailing Manual – September 2017
Revisions to the SDDM between published editions are issued through SDDM Revision Memoranda and are referred to as interim revisions. Requirements detailed in the memoranda are effective and enforceable on the effective date listed in the memorandum.

Drawings (Working Standards, Structures Design Drawings, Sample Sheets, and Borders)
Working StandardsWorking standards (WS) define the form, function and requirements of commonly used plan sheets. The working standard identifies areas requiring structural engineer input by a blue note. Update the working standard where indicated by the blue notes. Ensure that the working standard used is compatible with the design and details of a specific structure. The working standard becomes part of the sealed plan set, and the Engineer of Record (EOR) is responsible for all information on the working standard. Review the working standards, identify any areas of concern and inform the Structures Division of proposed changes to the working standard beyond the changes indicated by the blue notes. The Structures Design Manager must approve changes to a working standard in areas not indicated by the blue notes.

Sample SheetsSample sheets (SS) are examples of typical structure plan sheets. Use the sheets as a guide when preparing structure plan sets. Sample sheets depict typical layouts and information provided on structure drawings. Sample sheets guide users in developing plan sets and encourage consistency in presentation. Sample sheets do not depict specific requirements. For specific requirements refer to the SDDM written manual, checklists, working standards (WS), and structures design drawings (SD).
