Bridge repair often presents some of the most unique and difficult challenges of most any construction project. Given that much of the work often has to be done on components that are submerged in water. One of the early decisions contractors have to make is how to create a safe and dry work area.
While there are several options available for dewatering a work site. There is one in particular that rises above the others – inflatable cofferdams.
Installing an inflatable cofferdam provides a unique and temporary solution for granting access below the waterline in order to make repairs. Typical cofferdams require penetrating the ground and installing several different materials.
These options increase the subsurface risk due to the piling required, which can drive up the effect on the environment. Increase the overall cost of the project, and lengthen the schedule. However, an inflatable cofferdam is easily installed and removed quickly without the need for disturbing the existing environment.
Therefore, inflatable cofferdams provide temporary and affordable access to areas that are otherwise submerged for the length of the bridge repair. This effective seal around the worksite can be installed on virtually any type of lake or riverbed.
