Have you ever looked at a large bridge or other structure whose foundation was rooted underwater and wondered how engineers ever went about constructing it or will ever fix it? When construction needs to take place somewhere that is submerged underwater, engineers use a series of large driven piles into the waterbed called cofferdams to create a dry workplace.
