#Cofferdam is #temporarystructure to enclose the #construction area to build the #permanentstructures like #dams, #seawall, #oilplatforms , #bride'sfoundation or #piers. After constructing cofferdams, construction teams dewater the area to make it dry to work #safely in that dry area. The dry area is also important for good #workmanship and #quality of the works. Cofferdam also can be used to repair all the above-mentioned structures. After completion of the main work, it gets dismantled.
