Special Details

24: Guardrail Anchored in Back Slope Types 4B, 4T, & 4MGS-8: Reduced the length of the Type 4MGS-8 terminal on sheets 2 & 4 from 37’-6” to 34’-4½” using a non-standard beam element (length=9'-4 ½"). R-60-J: Guardrail Types A, B, BD, T, TD, MGS-8, & MGS-8D: Reduced the length of the transition from guardrail Type MGS to guardrail Type B or T by 3’-1½” (sheet 10) using the non-standard beam element (length = 9'-4 ½") on sheet 11. R-66-E: Guardrail Departing Terminal Types B, D, & MGS: Reduced the length of the departing terminal Type MGS on sheet 2 by 3’-1½” using a non-standard beam element (length=9'-4 ½"). R-72-D: W-Beam Backed Guardrail & Guardrail Long Span Installations: Deleted the 2’-8” offset from the face of the post to the hinge point in the detail at the top of sheet 8, since it is only applicable to the MGS long span details.

BRIDGE DESIGN 2.05 BRIDGE DESIGN QUALITY ASSURANCE & QUAILTY CONTROL (5-23-2016) 2.05.01 Overview A. To ensure bridges are designed correctly,

with no errors once the design calculations, drawings, and specifications are finalized, MDOT requires QA/QC procedures in accordance with this section.

B. The MDOT Bridge Design QA/QC

program consists of organizational procedures established to ensure a deliberate and systematic program that reduces the risk of introducing errors and omissions into bridge design final contract documents. The MDOT QA/QC program provides checks and balances within the organization to assure quality in final contract plans and specifications. The MDOT QA/QC program is implemented at different levels or phases of project activity, as defined in the MDOT Bridge Design Manual, the MDOT Road Design Manual, and the MDOT Quality Assurance and Quality Control Process Guide for Project Managers and as included in this section.

C. The rigor and level of resources allocated

to QA/QC applications on a given bridge are tempered by the size, complexity, and degree of redundancy in the structural system involved, and by the degree of standardization of the design. For major projects involving unusual, complex, and innovative features, a peer review may be desirable to raise the level of confidence in the quality of design and construction.

2.05.02 Definitions A. Quality Control (QC). Procedures followed within a unit or

working group to check the accuracy of the calculations, drawings, and specifications for the purpose of detecting and correcting design omissions and errors to accomplish the overarching goal of producing complete and error free final plans and specifications. QC occurs continuously throughout the course of a project.

B. Quality Assurance (QA). Review procedures followed by staff

outside the unit or working group to ensure the QC procedures were effective in preventing mistakes and promoting consistency in the development of bridge design calculations, drawings, and specifications.

C. Program Level Quality Assurance (PLQA). Review procedures followed by

management to assure the effectiveness of QC and QA procedures in verifying and measuring the level of quality of the entire bridge design QA/QC program.

D. Peer Review. A high-level QA review by a separate unit

or consultant not intimately involved with the design of the structure. Determination of the need for a peer review is made by the Bridge Design Supervising Engineer, with guidance provided by the State Bridge Alignment Team (SBAT).

E. Designer. An individual directly responsible for the

development of design calculations, drawings, and specifications, and review of shop drawings related to a specific bridge design.


BRIDGE DESIGN 2.05.02 Definitions (continued) F. Checker. An individual responsible for performing

technical review of design calculations, drawings, and specifications.

G. Reviewer. An individual responsible for performing

QA procedures that ensure that QC procedures were performed properly.

H. Engineer of Record (EOR). An individual responsible for all aspects of

the design of the structure, including the design of all of the bridge’s systems and components. This individual is appointed by the bridge owner, and must be a licensed Professional Engineer in the State of Michigan. For MDOT in-house projects, the bridge squad leader is the EOR, and signs, but does not seal the final contract plans. For consultant-designed projects, the EOR is the consultant Project Manager, and is required to seal and sign his/her portion of the final contract plans.


BRIDGE DESIGN 2.05.03 Implementing and Documenting Procedures A. Qualification of the Designer, Checker,

and Reviewer. The Designers, Checkers, and Reviewers

are key personnel providing well-designed, accurate, and constructible plans for use in the construction of bridges. The Designers, Checkers, and Reviewers must be experienced in structural designs and familiar with the current AASHTO bridge design and construction specifications and the MDOT Bridge Design Manual, Bridge Design Guides, and procedures.

1. Designer and Checker.

The following are the requirements for a bridge Designer and Checker.

a. Possess a professional engineer

(PE) license in Michigan with experience as a Bridge Engineer. A Designer or Checker without a PE license works under the direct supervision of a professional engineer licensed in Michigan who is the Reviewer and Engineer of Record for the project.

b. Non-engineer staff are often

utilized to design and check CADD drawings, develop quantity calculations and perform other non-structural design functions during the course of a project. As noted above, all work is done under the direct supervision of a professional engineer licensed in Michigan who is the Reviewer and Engineer of Record for the project.

c. The Designers’ and Checkers’

experience is commensurate with the complexity of the bridge being designed. Whenever possible, the experience of the Checker exceeds the experience of the Designer.

2.05.03 A. (continued)

2. Reviewer.

The Reviewer possesses a professional engineer (PE) license in Michigan, and has significant experience in bridge design and is familiar with MDOT’s bridge design and construction practices, procedures, and policies.


BRIDGE DESIGN 2.05.03 Implementing and Documenting Procedures (continued) B. Minimum Items/Areas Required to Be

Checked. Design calculations, design drawings, and

contract documents are required to be verified by a Checker with a thorough and comprehensive understanding of the project and design methods. In particular, the following minimum items/areas must be checked:

1. Design Computations and Checks.

All structural components, including deck, superstructure, and substructure components. The assumptions of the bridge design including general conditions and loadings are documented. Computations needed to determine type, size, and location of the bridge are checked including grade and quantity calculations.

2.05.03 B. (continued)

2. Bridge Contract Drawings Checks.

All components (as described above) of bridge design drawings are checked in detail. Plan notes are checked, including verification of correct materials specified. Plan notes must not alter the work, materials, or method of payment for standard pay items. All quantities and pay items are verified to be in conformance with plan details, and pay item wording checked against MDOT Standard Specifications for Construction or associated special provisions. In cases where the Designer is not the drawing Checker, the Designer at least reviews the drawings to ensure that they are in conformance with the design. After any required changes are made, names or initials are placed on the drawings indicating the individual who prepared the drawing, the individual who modified the drawing (as needed), and the Designer. The plans include the name of the unit or work area responsible for the plans. Consultant plans include their company logo.

3. Bridge Design Contract Document

Checks.

All special provisions are reviewed for appropriateness with respect to the contract plans and pay items and MDOT Standard Specifications for Construction. All permits, certifications, clauses and other supporting information are reviewed to ensure they are complete and correspond with the plans and remainder of contract package and that there are no conflicts between any documents.


BRIDGE DESIGN 2.05.03 Implementing and Documenting Procedures (continued) C. QC Procedures.

1. A supervisor or team leader is responsible for determining the necessary technical knowledge and experience of the Designer and Checker for that specific design. Designers and Checkers are assigned to bridge projects by matching experience and performance to project complexity.

2. The Checker is responsible to the

supervisor for quality control of the design, which includes checking the design calculations, plans, and specifications to assure accuracy and constructability. One hundred percent of all design calculations, quantity calculations, plans, and specifications are checked as part of the QC process.

3. All bridge plan sheets include the

names or initials of the person who drafted the details along with the Checker of the sheet and the date last revisions were made to that plan sheet. See Guidelines For Bridge Plan Preparation (MDOT Sample Plans Bridge) of Development Guide (Design Submittal Requirements Chapter 7) for guidelines related to drafting and plan preparation.

2.05.03 C. (continued)

4. All special provisions include the author’s initials and work area identifier, and are subject to a well-defined review process facilitated by MDOT’s Quality Assurance Section that includes various subject matter experts.

a. Unique special provisions

authored specifically for a project are drafted by the Designer or support area and submitted for review and approval during the course of the project.

b. Previously approved special

provisions can be used, and are reviewed by the Designer to assure that the entire content is appropriate for a project.

c. Frequently used special provisions

are utilized on projects as noted in specific use statements and are incorporated into the project without any changes.

5. Software programs such as MDOT’s

Bridge Design System, MDX, or Leap Bridge, various finite element modeling programs, among others, are often too complex for a Designer and Checker to review and confirm directly. The Designer and Checker must fully understand the methodology, assumptions, and limitations of each program prior to utilizing output on a project. This can be accomplished through review of all available program documentation and independent verification with hand calculations, spreadsheets or other known and proven software.


BRIDGE DESIGN 2.05.03 Implementing and Documenting Procedures (continued)

6. All design calculations include name or initials of the Designer and Checker along with the date designed and checked.

a. Hand calculations have a

“prepared by”, and “checked by” notation for each page of the calculations.

b. Spreadsheets, MathCad

calculations, and computer programs have a “prepared by” and “checked by” notation on the user input and results pages. These sheets are generated specifically for a project, or are utilized from a previous project, sometimes generated by others. The Checker is responsible for reviewing the data input, and the Designer and Checker must have a full understanding of the methodology, assumptions, and limitations of the program or spreadsheet and be able to verify that they are appropriate for the design.

7. All calculations are checked vs. the

Final Package Submittal for the project.

a. All dimensions, member sizes, bar

sizes from design calculations are verified to match plan dimensions.

b. Reinforcing steel takeoffs are

performed and verified for consistency between detail drawings and Steel Reinforcement Detail sheets.

c. A final cost estimate (project

verification estimate) is printed, and the wording for each pay item is verified for consistency between the cost estimate, plan drawings and (if applicable) special provisions.

2.05.03 C. (continued)

8. Calculations. At the completion of the project,

provide a set of design calculations for all elements of the bid package for the design file. All calculations include completed “prepared by” and “checked by” fields. Consultants provide calculations sealed/stamped and signed by the Engineer of Record for the project, who is licensed in Michigan. Design calculations are stored within the project file in ProjectWise and hard copies (if applicable) are stored in the MDOT Design Unit in accordance with the MDOT plan retention policy.

9. The design file includes (but is not

limited to) the following.

a. Design calculations.

b. Check calculations (e.g. to verify computer output, if applicable).

c. Supporting reports (e.g.

geotechnical recommendations).

d. Cost estimates including quantity calculations and supporting documentation

e. Review comments/resolutions.

f. Documentation substantiating the

completion of Quality Control and Quality Assurance procedures in accordance with this document and other accepted standards.


BRIDGE DESIGN 2.05.03 Implementing and Documenting Procedures (continued) D. QA procedures.

1. The MDOT Quality Assurance and Quality Control Process Guide for Project Managers provides a deliberate and systematic process for plan development and quality assurance. These processes are further defined in other sections of the MDOT Bridge Design Manual and the MDOT Road Design Manual.

2. The MDOT Design Division Quality

Assurance Section performs QA during The Plan Review, Plan Completion (Omissions and Errors Check) and Final Package Submittal stages of each project. The Quality Assurance Section reviews all project contract documents, facilitates department wide review, and documents all review comments in accordance with section 14 of the MDOT Road Design Manual.

3. In accordance with National Bridge

Inspection Standard requirements, a load rating is performed for each bridge rehabilitation and bridge replacement/new construction project. For bridge rehabilitation projects, a preliminary load rating is typically performed at The Plan Review stage, and finalized at the Plan Completion stage. For new or reconstructed bridges, load rating is typically performed at Plan Completion stage. Load rating calculations serve as a QA of structural design of the beams for projects, and feedback is provided to the Designer if deficiencies are discovered.

4. MDOT’s Bridge Field Services (BFS)

section performs QA at the Plan Completion (Omissions and Errors Check) stage of each project. BFS maintains a plan review checklist

2.05.03 D. (continued) comprised of focus areas for plan reviews based on past experience with construction issues. BFS focuses specifically on constructability and structural fabrication aspects of bridge projects and provides feedback to the designer for incorporation into the final project package.

5. QA is performed by the project

supervisor or team leader at various times during the project and at The Plan Review, Plan Completion, and Final Package submittal stages. While QC is performed on one hundred percent of project documents, the level of QA performed by the supervisor or team leader is subject to the supervisor’s discretion based on a combination of factors such as experience of the Designer and Checker, complexity of the project, uniqueness of project parameters and details.

6. PLQA is performed by the Bridge

Design Supervising Engineer to ensure that the bridge design units, consultant coordinators, and consultant design teams are performing adequate QA/QC in accordance to this document. This involves periodic review of a representative sample of bridge design units and consultant coordinator projects at selected project milestones. The Bridge Design Supervising Engineer may assign peer reviews to promote consistency and uniformity between MDOT working units and between MDOT in-house and consultant designers. Performance measures will be developed and used to track progress in key areas.

7. If the QA review shows evidence that

the proper QA/QC process is not being properly followed, a more rigorous review of the QA/QC process documentation is performed, and recommendations are provided.


BRIDGE DESIGN 2.05.03 Implementing and Documenting Procedures (continued) E. In-House Design Quality Control/Quality

Assurance. All bridges designed by MDOT are

reviewed in compliance with this document and the referenced manuals and procedures. Each work unit documents a process for implementing the procedures to assure consistency within the Bridge Design Section.

F. Design Consultant Quality Control/Quality

Assurance.

1. Every consultant performing bridge design for MDOT is required to have its own QA/QC process in place. As part of the prequalification application, each consultant must submit a Quality Control Plan in accordance with the MDOT Consultant Prequalification Instructions. The QA/QC program document is available to the MDOT consultant coordinator to review as necessary throughout the course of a project.

2. Project proposals define the QA/QC

program and responsibilities specific to a project. In general, each prime consultant and sub consultant follows their own documented QA/QC procedures on file with their prequalification. Additionally, the prime consultant for a project is responsible for project level QA of sub consultant’s deliverables to assure uniformity within the project and to assure that sub consultant’s procedures are being followed. Documentation of QA/QC procedures for a specific project will be furnished to MDOT at any point during a project upon request.

2.05.03 D. (continued)

3. At the completion of a project, the consultant furnishes the completed design package, including all design calculations, quantity calculations, and documentation of completed QA/QC along with a letter certifying completion of QA/QC.

4. Consultant design contracts have

clauses protecting MDOT from design errors and omissions by requiring that the consultant’s work meet “sound, prudent, appropriate, and required professional standards and practices,” and that the consultant will promptly revise work that does not meet MDOT criteria, at no additional cost to MDOT.

5. The consultant coordinator or project

manager assures that the documented QA and QC program is followed by the consultant in accordance with this document and the project QA/QC program by performing cursory checks of submittals and contract documents throughout the course of the project and requiring changes as appropriate. Additionally, consultant coordinators will verify reasonableness of the design based on knowledge of design standards and engineering judgement.

6. At the completion of each project,

consultants are rated via performance evaluations. Past performance is a part of the scoring criteria for proposals for all Quality Based Selections. Consultants are also scored based on the experience of their QA/QC review team and the quality of their QA/QC plan as detailed in a project proposal.


BRIDGE DESIGN 2.05.03 Implementing and Documenting Procedures (continued) G. Corrective Actions.

QA/QC procedures are implemented on all projects. Through the PLQA, the overall program is continually monitored for effectiveness. When level of QC or QA is found to be insufficient, corrective actions are required.

1. The following actions are taken if QA

or PLQA reviews indicate that a specific design unit, consultant, or consultant coordinator is not following the process.

a. The representative sample of

projects for that unit or coordinator is increased until the Bridge Design Supervising Engineer is satisfied that the issue is corrected.

b. Concerns with consultant’s

performance are noted on consultant’s review at the completion of the project.

c. Concerns with MDOT staff

member’s performance are reflected in the staff member’s annual performance review or interim performance review, depending on severity.

2. If, during the review of project

submittals, it is evident that the consultant team has not followed QA/QC practices, payment for hours associated with QA of a project as negotiated prior to the start of a project can be withheld.

2.05.04 Role of Federal Highway Administration (FHWA) A. Initial Review and Approval of Program. The general role of FHWA Division Office

is to review each State Highway Agency (SHA) QA/QC Program and to ensure the QA/QC program is thorough, effective, documented, and followed. Further, it is the role of the FHWA Office of Bridge Technology to assure uniformity within division offices regarding implementation of this guidance.

B. Periodic Program Reviews. FHWA division offices may perform

periodic reviews of the MDOT’s programs. Upon request, MDOT will provide project documents to the FHWA division office for review, in accordance with the Federal-Aid Stewardship Agreement. The need of periodic reviews depends on the complexity of the bridge projects.


BRIDGE DESIGN 2.05.05 References and Other Sources of Information A. MDOT Bridge Design Manual The procedures involved in preparing

bridge plans, quality control and quality assurance are interlaced within Chapters 2 – 6 as well as Chapter 15.

B. MDOT Road Design Manual

Procedures for plan preparation are addressed in Chapter 14.

C. The Quality Assurance and Quality

Control Process Guide for Project Managers

Documents the MDOT QA/QC process for

preparing road and bridge projects, and is based on a well-documented plan development procedure.

D. Program/Project Management System

(PPMS) Task Manual Documents the preconstruction process

as it pertains to project development. Networks based on the PPMS Tasks are used to plan and to track virtually every aspect of a project design schedule.

E. Guidelines For Bridge Plan Preparation

(MDOT Sample Plans Bridge) Bridge sample plans including plan sheet

examples of typical plan set detailing preferred details and drafting procedures.

CHAPTER 6

PLAN SHEET EXAMPLES

6.00 INTRODUCTION (5-23-2016) Plan sheet examples can be found at Guidelines for Bridge Plan Preparation (MDOT Sample Plans Bridge). The document presents samples of detail sheets that can be used as guides in preparing plans of highway bridges. The samples were selected and tailored to provide as much reference data as possible on a limited number of sheets. Each of the detail sheets of a typical set of plans is represented. At the same time, detailing procedures for a variety of bridge types are illustrated. Commentary is provided for more clarity and background on guidelines and detailing procedures. Also included are abbreviations, symbols and naming conventions for files. In general, adherence to these guides is recommended. Many of them result from past construction experience, and while other methods of presenting structural details may be equally effective, it is possible that they would create problems. The format shown is preferred if for no other reason than the familiarity that the state contractors have developed following it on previous jobs. On rare occasions, the guides may not be appropriate, but before electing to deviate, drafting personnel should be sure there is ample justification. (2-23-2001)

MICHIGAN DESIGN MANUAL BRIDGE DESIGN

CHAPTER 9 DETAILING PRACTICES 9.00 DETAILING PRACTICES (5-23-2016) Drafting details and practices, cell libraries and other miscellaneous files can be found on the MDOT Design Services Website. (8-20-2009) (5-28-2013) Various details have been standardized and appear on specific sheets. See Guidelines For Bridge Plan Preparation (MDOT Sample Plans Bridge) of Development Guide (Design Submittal Requirements Chapter 7) for various details, practices and sample plan sheets. It also contains drafting degrees of accuracy, abbreviations and symbols used on plans. For naming convention of files see Chapter 3 of Development Guide (Design Submittal Requirements). Structure designations and additional bridge/structure information is available in the Michigan Structure Inventory and Appraisal Coding Guide. Checking of all detail drawings must be done to assure the accuracy of the plans. The drawings shall comply with the design calculations, existing design guides, and the practices listed in Guidelines For Bridge Plan Preparation and Section 2.05, Bridge Design Quality Assurance & Quality Control.
