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.

Current SDDM Written Manual

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.

Written Manual

The written manual provides technical direction and expands upon and clarifies design and construction requirements as specified by AASHTO Specifications.

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 Standards

Working 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 Sheets

Sample 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).

Borders

The standard Structures Division border, StructBorder.dgn (45 KB), is for use on UDOT projects.

Checklists

Checklists are provided to assist with the development and review of plans, design detailing and working drawings. Not all checklists are submittal documents, refer to the PDN and description on the individual checklist to see if submittal is required. Regardless of submittal requirements, checklists are recommended for use as appropriate, however checklists are not all inclusive and the engineer must review the documents and include all information required to construct the structure and meet the design intent.

SDDM Revision Memoranda

Revision Memoranda

A SDDM Revision Memorandum establishes interim revisions to SDDM policies, procedures, practices and technical requirements. The Structures Division issues memoranda as needed to ensure that the SDDM remains up to date and appropriately reflects changes in needs and requirements.

Requirements detailed in the memoranda are effective and enforceable on the effective date listed in the memorandum and in the SDDM Revision Log.
