Structures & Geotechnical Guidance and Manuals

The following documents provide technical direction and describe the Structures Division goals, expectations, processes and procedures for performing structural and geotechnical work for the Department.

Bridge Management inspects, monitors, reports and effectively manages UDOT’s structure inventory using in service inspection data to measure the overall condition of each bridge and prioritize projects for the Bridge Programs.

Structures Design and Geotechnical Design provide structural and geotechnical engineering services, manage structure design and construction, and establish and maintain structural and geotechnical design criteria and standards to ensure a safe, economical and reliable transportation system.

Structures Division Quality Control/Quality Assurance (QC/QA) Procedures

The UDOT Structures QC/QA Procedures define the Structures Division’s expectations, processes, procedures and requirements for performing QC/QA of structural work. The procedures are a tool and cannot replace the sound judgment and experience of competent professionals. Implement the Structures QC/QA Procedures on all deliverables and according to the stages, activities and guidelines in the UDOT Structures Design and Detailing Manual (SDDM), the Geotechnical Manual of Instruction (GMOI), and the Project Delivery Network. Structures QC/QA Procedures consist of five independent roles:

Design
QC check
QA audit
Reviews
Acceptance

Structures QC/QA Procedures – February 2015

Requests

The Structures Division maintains structure records for bridges and miscellaneous structures. The Structures Division is responsible for assigning and tracking unique Structure numbers and managing initial in service bridge inspections.

Use the following to facilitate structure specific requests:

Unique structure numbers are required for new bridges, replacement bridges, and state owned box culverts with a span as measured along the centerline of the roadway or an inside rise dimension of 10 feet or more.

Updated drawing numbers are required for the modification, preservation, or rehabilitation of existing bridge structures.

All structures over 20 feet in length (either newly constructed or rehabilitated) require an in service bridge inspection.

An in service inspection is required before opening a structure to traffic. If Structures Division schedules allow, the in service inspection may be scheduled to occur concurrently with the Substantial Completion walk through.

Findings at the in service inspection may delay opening of the structure to traffic. To avoid delays, ensure requests for in service inspection are requested far enough in advance to provide adequate time to correct any found deficiencies.

Existing Structure Plans and Reports

Existing structure plans and reports are available to local owners, consultants and contractors, and members of the general public. Different methods to request structure plans and reports are provided below:

Accelerated Bridge Construction (ABC) Information

Accelerated Bridge Construction (ABC) is common practice in Utah. The Structures Division has widely implemented the use of ABC. See below for a selection of Lessons Learned Reports and Project Highlights from some of our past ABC projects.

ABC design documents and supporting drawings have been incorporated into the Structures Design and Detailing Manual (SDDM) which consists of the Written Manual, Drawings, and Checklists. The SDDM references ABC decision making tools which are provided below.
For your convenience, hyperlinks are provided inside the drop down menu connecting to the locations where the referenced resources can be found.

ABC SDDM Resources

Resource	Description
Written Manual
Written Manual: Chapter 20	Chapter 20 of the SDDM Written manual specifically addresses ABC, providing information on the decision making process, ABC methods, and technical criteria.
Drawings
Working Standards (WS) define the form, function and requirements of commonly used plan sheets. The Working Standard identifies areas requiring engineer input by a blue note. The Working Standard sheet becomes part of the sealed plan set, and the EOR is responsible for all information on the Working Standard
WS-3	Prestressed girder shear stud and haunch details for full depth deck panels
Structures Design (SD) drawings are a design aid and list specific design requirements or details. Structures Design drawings are not plan sheets and are not included in plan sets.
SD-9 Series	Full depth precast concrete deck panel design guidance
SD-6 Series	Precast concrete substructure element design guidance
Sample sheets (SS) are examples of typical structure plan sheets and are used as a guide when preparing structure plan sets. They guide users and encourage consistency in presentation but do not depict specific requirements.
SS-14 Series	Precast concrete substructure sample sheets
SS-32 Series	Full depth precast concrete deck panel sample sheets
SS-33 Series	Precast concrete approach slab sample sheets
Checklists
Checklists are provided to assist in developing and evaluating projects and plans. Checklists are not all inclusive, but attempt to address basic requirements as well as common concerns.
ABC Heavylift Project Checklist	Heavy lift ABC projects include structures moved with SPMTs or similar equipment, lateral structure slides, structures trucked in and placed with cranes, and structures longitudinally launched.
Precast Elements Design and Detailing Checklist	Checklist for design and detailing of precast elements
Precast Elements Shop Drawing Review Checklist	Checklist for shop drawing review of precast elements

ABC Decision Making Tools

The ABC decision making process consists of two steps — completing the ABC rating procedure spreadsheet and then using the rating in the ABC decision flowchart to determine if an ABC approach is required.

ABC Rating Procedure Spreadsheet and Decision Flow Chart

Digital Delivery

Digital Delivery with Model Based Design and Construction (MBDC) is the use and transfer of digital data in design, construction, and asset management. Digital Delivery with MBDC is not solely intended to eliminate plan sheets but rather deliver data in more directly consumable formats for project stakeholders.

Go to the Digital Delivery page for more information on UDOT’s current Digital Delivery and MBDC efforts.
