Staff recommends replacement of Venetian Gardens Bridges with wooden structures similar to existing, through a design-build procurement method, with a total budget not to exceed $365,000.
Several months ago, Commission received a briefing on the condition of the Venetian Gardens bridges, maintenance issues associated with the bridges and several possible options for replacement. Following that meeting, the City Manager directed staff to further evaluate the options and develop the project.
It was apparent that the cost of steel or aluminum replacements exceeded the funds available for the project. It is also apparent that all but one of the bridges require replacement.
After further review, staff reached several conclusions: first, funding constraints limit the style and materials of replacement bridges to wooden bridges; second, replacement wooden bridges should address maintenance and durability issues; third, replacement bridges must conform to ADA requirements.
Staff sought input from two separate contractors. One contractor was recommended to the city by a reputable local contractor who specialized in highway and site work; the other contractor was the one who had originally constructed the bridges. Independently, both contractors offered the opinion that replacement with wooden bridges was likely to be the most cost-effective solution. Both contractors opined that it may be possible to salvage some of the pilings, but at the expense of aesthetics. Both contractors gave similar informal estimates of cost. One contractor recommended that a design-build approach offered several advantages to the city.
In addition, staff sought input from an engineer with experience designing and constructing similar bridges in park settings throughout Florida. He concurred with the design-build approach. He also offered a number of suggestions for cost-effective replacements.
In aggregate, the recommendations from contractors and the engineer lead staff to make the following recommendations:
1. Replace Venetian Gardens bridges as described with a total budget of $365,000; or,
2. Such alternative action as the Commission may deem appropriate
for this project, if approved will be 2004 b ond
