Titusville Memorial Fishing Pier
Brevard County, Florida

DRMP provided structural engineering design for a 540-foot fishing pier adjacent to the Intracoastal Waterway to replace the existing pier that was damaged by vessel impact and storm driven waves.  The replacement pier consists of a C.I.P. flat slab superstructure made integral with 30-inch voided precast concrete piles.  The end of the pier includes a 45-foot square diamond configuration to resist wave and vessel generated forces.  Sight specific wave induced force interaction with the pier and vessel impact was evaluated by finite element modeling of the proposed pier.

Mainline Turnpike Widening from Beulah Road to SR 50
Florida’s Turnpike Enterprise

DRMP was responsible for providing transportation engineering design for this limited access facility on Florida’s Turnpike.  The design involved the widening of 4.6 miles of Florida’s Mainline Turnpike from the existing four lanes to eight lanes with a construction estimate of approximately $87 million.  The limits of the project were from Beulah Road to SR 50 within the Central Florida community area.  This project was required to increase capacity for both long distance travelers and local commuters.  This project included the reconstruction of the SR 50 interchange, which was converted from a partial diamond with a loop ramp to a full diamond interchange and also included two new ramp toll plazas.  It also included the addition of one lane in each direction for one mile of SR 50.

This project included the phased removal and reconstruction of the twin mainline bridges over Avalon Road, the removal and replacement of Winter Garden Vineland Road over the Turnpike and the inside and outside widening of the twin mainline bridges over SR 50.  The widening at SR 50 was complicated by existing MSE retaining wall at the end bents which required partial removal and reconstruction to resist additional earth loading imposed by the widening.  Two bridges north of SR 50 were modified with tie back walls to accommodate a proposed northbound on-ramp.  Also, included were over three miles of precast and cast-in-place sound walls.

DRMP provided ITS design for a 5-mile section of the Turnpike’s ITS system including Radar Vehicle Detection Sites, Travel Time System, CCTV sites, and DMS sites.  Significant analysis was performed on the installation of the Radar Detectors around sound walls to determine if the sound walls would interfere with the operation of the radar devices.  Drainage engineering for the project included the design of 14 stormwater ponds that included wet detention ponds, dry retention swales with underdrains and a cascading dry retention pond system within a landlocked basin.  The stormwater management design accommodated maintaining flows from large offsite areas without the costs of separate conveyance systems or increased volume in the treatment ponds while meeting stormwater criteria for standard Environmental Resource Permitting (ERP) from St Johns River Water Management District (SJRWMD).   DRMP’s drainage engineers were able to minimize the purchase of right-of-way by using treatment swales and minimal offsite ponds while dealing with the challenges of providing stormwater treatment for portions of the  roadway built in a cut section (below adjacent properties).

Center Fixed and South Fixed Bridge Replacement
Gasparilla Island Bridge Authority

DRMP provided structural engineering design to replace the South Fixed Bridge and Center Fixed Bridge located on GIBA’s 2.5 mile private road on the Boca Grande Causeway.  The two fixed bridges are critical to the transportation needs of the public as they are the only land link between Placida in Cape Haze and Gasparilla Island. Both bridges were nearing the end of their service life span and were considered to be “functionally obsolete” and “scour critical.” The new bridges were designed higher than the existing structures which required reconstruction of the roadway approaches.  The bridge designs also included consideration of significant anticipated scour, vessel impact and wave impact forces. Bulkhead walls were designed to protect the abutments.

Lake Mary Pedestrian Overpass  

Lake Mary Pedestrian Overpasses
Seminole County

DRMP was responsible for the design and plans production of two pedestrian bridges spanning Lake Mary Boulevard.  Each of the bridges’ main span superstructures crossing Lake Mary Boulevard consists of a single 153-foot span comprised of custom L-shaped prestressed beams.  The custom L-shaped beams included complex design analysis to evaluate prestressing of a no-symmetrical cross section and unique considerations for transporting the members to the site. The main span beams were designed such that the deck slab is supported on the bottom flange of the beams.  The ramps are comprised of ADA compliant precast slabs and landing components supported by cast-in-place columns and footing caps.  The foundations are made up of a combination of pile supported piers in pond locations and shallow spread footings at the remaining locations.  The bridge architecture features a highly decorative safety enclosure and decorative façade panels at the main span piers that reflects the look of the Rialto Bridge in Venice Italy.
