Bridge Design and Construction
The City of Cape Coral has over 400 miles of canals and 130 bridge crossings. As the project design report was initiated, it was decided that this project would be the first to establish aesthetically pleasing bridges. Accomplishing this would prove to be a challenge in order to meet the crash criteria in accordance with FDOT road and bridge standards.
The Texas DOT had a prototype design that was used as a basis for the Del Prado project. All cast-in-place walls produced a functional look that blended well with much of the residential architecture throughout the City. All of the bridges were further decorated with ornate aluminum railing which also fulfilled the bicycle rail requirements for these bridges.
More than 200 parcels needed to be acquired when the project began. In an effort to expedite the construction, it was decided that kicking off the bridge construction before the roadway improvements would provide a solution. Working closely with the Public Works Real Estate Division, the City Attorney, and outside legal counsel, Balfour Beatty was able to seamlessly organize the construction according to acquisition and successfully complete all five bridges.
As the main corridor for all telephone communication in the North Cape, Del Prado Boulevard private utility companies were brought in early in the construction planning process to make sure everyone's concerns were understood and taken into consideration. As a result, teamwork allowed for more than two miles of telephone lines to be relocated in accordance with the construction schedule.
Digital As-Built Technology
Eye level digital photography technology was used to update roadway construction each month. Unique to transportation projects, this technology allows a 360-degree view of the roadway every 100 feet. As a means to track pre-existing conditions as well as construction progress, this is an effective tool that Balfour Beatty was able to share with the client, property owners, and anyone interested in looking at the project from their PC.
Low Impact Development (LID) systems and bio swales were used to remove silt pollution. The project has incorporated the use of rain gardens - a growing trend in protecting water quality. The planted depressions capture and absorb water runoff from impervious paved areas, such as streets and parking lots. Rain gardens improve water quality by keeping surface water, including pollutants, from flowing into storm drains or nearby ponds and streams.
