BRIDGE DESIGN SECTION ORGANIZATION

CHAPTER 1 BRIDGE DESIGN SECTION ORGANIZATION

This Chapter presents the organization of the Bridge Design Section and discusses the responsibilities of the functional units within the Section.

1.1 BRIDGE DESIGN SECTION

In general, as part of the Preconstruction Division, the Bridge Design Section is responsible for the design and project coordination for new bridges, bridge widenings and, occasionally, bridge rehabilitation projects. Figure 1.1-1 illustrates the functional organization of the Bridge Design Section. The following discusses the responsibilities of each functional unit within the Bridge Design Section.

1.1.1 State Bridge Design Engineer

The State Bridge Design Engineer is responsible for the overall engineering, administrative, and management activities of the Bridge Design Section. The State Bridge Design Engineer establishes overall Department structural policies and determines the Section's coordination with units outside of the Bridge Design Section. The functional responsibilities of the State Bridge Design Engineer are to:

? lead the administrative and management activities for the Bridge Design Section (e.g., develop budgets, manpower management, schedule meetings);

? develop work programs for bridge projects for inclusion in the Department's annual and 5-year program of projects;

BRIDGE DESIGN SECTION ORGANIZATION

? participate in professional organizations related to bridge design (AASHTO, TRB, AWS, etc.) to represent the Department s interests and concerns;

? oversee the development of:

+ new and revised sheets for structural designs in the SCDOT Bridge Drawings and Details, available at the SCDOT website;

+ revisions to the SCDOT Bridge Design Manual;

+ structural specifications (in a participation role) for the SCDOT Standard Specifications for Highway Construction; and

+ the structural design criteria used by the Bridge Design Section;

? determine the Bridge Design Section's appropriate participation in public hearings and public informational meetings for projects where the Bridge Design Section is the lead unit;

? remain abreast of the key issues on individual bridge projects;

? determine the Bridge Design Section's course of action for any special studies, reports, etc., upon request from the State Highway Engineer, FHWA, etc;

? serve as the Section's focal point for coordination with FHWA, other SCDOT units, etc.;

? provide final approval to all structural plans;

? ensure that work is implemented according to the Bridge Design Section's policies and that it complies with the appropriate design standards and criteria; and

? ensure that the project design and construction plans are completed on schedule.

1.1.2 Seismic Design and Bridge Design Support Team

The Seismic Design and Bridge Design Support Team is responsible for seismic training and for maintaining the SCDOT Seismic Design Specifications for Highway Bridges and its compliance and updates. The Seismic Design and Bridge Design Support Team supports the Bridge Design Teams with any seismic-related issues from the preliminary stages of the bridge projects until the structural design is complete. The Seismic Design and Bridge Design Support Team also works closely with the Geotechnical Design Section to ensure consistency between the structural and geotechnical seismic-related elements of the design.

The Seismic Design and Bridge Design Support Team is responsible for the following:

? reviews preliminary and 95% bridge plans and provides comments to ensure compliance with the Department's seismic requirements;
