Arrow Bridge Replacements on MD 28 and MD 450, Frederick County and Anne Arundel County, Maryland

Technology Transfer

The MD 28 and MD 450 bridge projects were included as representative projects for an HfL demonstration project showcase on July 22, 2008 in Frederick, Maryland. The focus for this showcase was PBES practices and technologies, and the meeting agenda is presented as Figure 28 .

The project showcase included projects and representatives from HfL projects in three states: Maryland, South Carolina, and Virginia. Officials from MDSHA, South Carolina Department of Transportation (SCDOT), and Virginia Department of Transportation (VDOT) along with the corresponding FHWA Divisions joined the HfL team in developing and implementing a technology transfer program focused on PBES.

In addition to the HfL project team, about 75 participants from 6 states (MD, SC, VA, PA, WV, NC) and the District of Columbia attended the project showcase in Frederick. After opening words from MDSHA (as host agency), HfL, and FHWA, each demonstration project was presented as a joint demonstration, incorporating input and comments from both the agency’s and the contractor’s perspectives. The meeting agenda is shown in Figure 29 .

Doug Rose, Deputy Administrator of MDSHA, opened the workshop with a brief welcome statement, followed by an overview of the HfL program by Nelson Castellanos, Delmar Division Administrator of FHWA, summarizing the goals and intent of the showcase meeting as well as the HfL program overall.

Vasant Mistry of FHWA gave a comprehensive presentation of the state of the industry for PBES throughout the U.S. This presentation focused on the theme of accelerated bridge construction and how these technologies have been utilized throughout the states, as well as graphical depictions of using various PBES throughout construction staging. Finally, Mr. Mistry discussed FHWA resources and initiatives available to promote the use of PBES, generally found at www.fhwa.dot.gov/bridge/prefab.

Jeff Robert, Project Engineer & Coordinator for MDSHA, and Butch Lundgren of Concrete General, Inc. delivered an overview presentation of the MD 28 and MD 450 projects. This presentation covered the pre-design summary of the projects, including site photos, traffic impact and MOT alternative studies, and comparative projects of similar scope. Mr. Robert and Mr. Lundgren also presented the review and application of strategies to these projects within the HfL program goals, primarily focused on public awareness and the utilization of PBES, from both the agency and contractor perspectives.

Khossrow Babaei and Robert Price of VDOT presented the US 15/29 over Broad Run bridge project. Special focus was given to the review and justification of multiple PBES construction alternatives and the corresponding MOT alternatives given various construction staging options. Additional discussion included details and photos of handling various construction issues (i.e. high water, beam conflicts) and the extension of abutments and piers for bridge widening.

Bener Amado and Randy Cannon of SCDOT presented their project on SC 377 near Williamsburg, South Carolina. Major focus areas of this presentation included innovative contract bidding and incentive/disincentive clauses for schedule performance and the use of self-consolidating concrete (SCC) in beam fabrication. This presentation also included significant comments from the contractor’s perspective of all aspects of the project.

The project showcase was originally scheduled for this day in Frederick in hopes to coordinate with the MD 28 project and make a site visit to the project location on the day that the precast slabs were to be placed. However, unforeseen project delays were realized as a result of inaccurate determination of bedrock depth for pile placement at the time of abutment construction. Therefore, the project was behind schedule and the site visit was replaced on the showcase agenda with a slideshow presentation of the project activities to date from Jerry Burgess, the MD 28 Field Project Engineer for MDSHA.
