The Florida Fish and Wildlife Conservation Commission (Commission) has identified a need for the inspection and repair of aquatic revegetation fences on Lake George, and potentially other water bodies in the St. Johns River. Aquatic revegetation projects frequently require fence enclosures to reduce grazing pressure on planted vegetation. Reducing herbivory often results in more predictable establishment of vegetation in less time. The Commission’s fenced enclosures are constructed using fencing wire attached to steel T-posts. To increase visibility for navigation, and to reduce chafing, all posts are covered by PVC pipe. Fences are normally constructed in less than four (4) feet of water. Table 1 provides specifications of fencing products utilized in fence construction and to be used to fulfill the provisions of this bid. All materials necessary for repair under this bid will be provided by the Commission. Figure 1 pictorially depicts basic construction methodology. The fences are meant to be temporary but may be required for several years before vegetation has become sufficiently established to warrant their removal. Over time, fence enclosures are subject to damage from wind and wave action, accumulation of vegetation and other debris, damage from birds, turtles, alligators, unwary boaters, and vandalism. As such, the structures require periodic inspection and repair to preserve their structural integrity and function until the fence is removed.
