TITLE

    Design Build Projects Design Quality Management Plans

BACKGROUND / NEEDS STATEMENT

    Agencies need different quality assurance and control protocols that are consistent with and take

    advantage of new project delivery methods. The purpose of this proposed research is to gather

    information on how Federal and State Departments of Transportation (DOT’s) are developing and

    coordinating design quality management for Design Build (D-B) projects during project development and

    contract administration. This can be accomplished by visiting agencies which have good D-B experience

    and documenting their best practices and lessons learned.

DOT’s are more frequently utilizing D-B contracting for their road and bridge projects. The D-B method

    can present special challenges to the development and review of design submittals. Under D-B, there

    may not be one set of design plans, but multiple design submittals, possibly one for each element of

    design or segment of a project. For instance, it would not be unusual for a design-builder to provide more

    than 100 design submittals to the DOT to review and approve on a large project.

    Many DOT’s may not have fully developed or well defined policies and procedures for Design Quality Management for the D-B delivery method. The recently released NCHRP Synthesis 376 Report states

    that additional study is warranted due to the “lack of clear guidance on how to properly develop and

    administer design quality management activities in the D-B context.” The topic is uniquely different than

    construction quality control and assurance which is more routinely delegated to consultant staff and for

    which there are established and quantifiable measurements.

Formal procedures may not be available for DOT’s to follow during the procurement phase to ensure

    design quality management includes:

    o Determination of % design performed prior to advertisement (this may vary by discipline)

    o Development of procurement documents based on project risks and opportunities

    o Determination of the scope of the procurement (Traffic Control Plan, Environmental Documents,

    Access requests, etc…)

    o Clear requirements for design submittals

Guidance that is not available for DOT’s to follow during the contact administration phase to ensure

    design quality management includes:

    o Determination of what needs to be reviewed

    o Determination of who performs the reviews

    o Determination of frequency/staging for the reviews

The proposers are not aware of current studies under way for this topic. There are, however, several

    agencies with meaningful experience with D-B that may be good sources of information. Such agencies

    include: FHWA Federal Lands Highway Division (FLHD), the USACE, Florida DOT, Minnesota DOT,

    North Carolina DOT, Texas DOT, and Utah DOT.

This proposed research is timely because several DOT’s have recently started large D-B projects and it

    follows a 2008 NCHRP report that details the importance of “Quality Assurance in Design Build Projects.”

RESEARCH OBJECTIVE

    The proposed research will identify best practices, policies, case studies, sample request for proposal

    requirements, and lessons learned for Quality Assurance review and acceptance of Design Build design

    plan submittals. The research will also identify essential elements that a DOT should expect from the

    Design-Builder for design quality control and assurance that it is satisfying its contractual obligations.

WORK TASKS

    Document successful practices among agencies that have established formal or informal procedures for

    the procurement phase to ensure design quality management including:

    ? Determine relevance of % design performed prior to advertisement (this may vary by

    discipline)

    ? Development of procurement documents based on project risks and opportunities

    ? Determination of the scope of the procurement (Traffic Control Plan, Environmental

    Documents, Access requests, etc…)

    ? Clear requirements for design quality management plans and design submittals

    ? Provide guidance or a summary of best practices for the contact administration phase to ensure

    design quality management:

    o Determination of what needs to be reviewed

    o Determination of who performs the reviews

    o Determination of frequency/staging for the reviews

URGENCY

    This proposal is timely because several DOT’s recently started large D-B projects and it follows a 2008 NCHRP report that details the importance of “Quality Assurance in Design Build Projects.” D-B is likely

    to be a more common project delivery method for DOT’s. Design quality, now managed by the contractor, is the first essential element of assuring quality in the constructed facility.

FUNDING REQUESTED AND TIME REQUIRED

    It is estimated that this research will take 11 months to complete and will require $99,000.
