DESIGN BUILD

DRMP is responsible for the design and plans preparation for this design build project in conjunction with Lane Construction Corporation.  The project is located within the City of Titusville, Brevard County east of US 1 along SR 406. The principal intent of this project is to replace the existing A. Max Brewer Bridge (Bridge No. 704049) and South Relief Bridge (Bridge No. 704125) with a replacement bridge, which will be one single structure with a length of 3,500 feet.  The high-level bridge shall be designed to carry two 12-foot lanes (one in each direction) with 8-foot outside shoulders, and 5-foot wide sidewalks separated from the shoulder by a standard F-Shape traffic railing barrier. A pedestrian/bicycle railing was provided on the outsides of the sidewalk.  A proposed recreational fishing pier will be located at the end of the West Causeway and will extend into the river parallel to the proposed high-level bridge.

DRMP served as the lead design firm responsible for nearly all aspects of design, except for the architectural plans of the toll plaza, and geotechnical design.  DRMP performed this project with the contractor, Southland Construction.  This project entailed expanding the Leesburg Toll Plaza from 10-lanes to 14-lanes, and a positive concrete barrier wall was installed to eliminate the possibility of head-on collisions.  The improvements included a trench drainage system to collect stormwater runoff from the wide expanses of pavement of the Plaza.  The existing barrier was extended to the east, including extending the access tunnel beneath the roadway, and exclusive electronic toll collection lanes created to serve the growing percentage of users that utilize the SUNPASS system of Electronic Toll Collection.  Due to tourist traffic to Florida, this particular plaza experiences the highest number and highest percentage of cash toll transactions, so maximizing the capacity of conventional cash lanes while maintaining a high level of traveler safety was appropriate.

DRMP served as the lead design consultant along with Southland Construction as the lead contractor and Middlesex Corporation as the asphalt contractor for this project.  This project reconfigured the interchange serving as the main entrance into Orlando International Airport, by constructing a new fly-over directional ramp for the westbound to southbound movement, replacing an existing cloverleaf ramp in the northwest quadrant, so that weaving and merging traffic operations were significantly improved.  The project also widened and repaved 1.3 miles of SR 528 (six-lane expressway), widened and repaved 1.1 miles of SR 436 (six-lane divided primary arterial).  Two new bridges were constructed, a curved steel box girder over NB SR 436, and a steel plate girder bridge over SR 528, as well as widening on three AASHTO girder bridges.  Extensive retaining walls were required, of MSE wall construction and tie-back (Schnabel) construction.

DRMP was involved in this design build project as a subconsultant to URS Corporation and Granite Construction, Inc. for FDOT District Five.  Design build was the chosen method of procurement in order to get the project open to the daily commuter traffic quickly.  The entire project called for a complete replacement of the bridge over the St. Johns River, plus reconstructing several interchanges and adjacent crossroads over I-4.  Specifically, DRMP was responsible for providing topographic survey, bridge design, roadway and drainage design, signing and pavement marking and signalization for the cross road of Enterprise Road over Interstate 4.
