cofferdam

[ˈkɔːfərˌdæm ]

Definition

Context #1 | Noun

construction project

A cofferdam is a temporary structure designed to hold back water to create a dry work environment for construction projects. It is typically used in situations where underwater construction is required, such as bridge foundations or pumping stations. Cofferdams can be made of various materials, including steel, wood, or concrete. They are essential in preventing water from flooding the construction site, allowing workers to safely complete their tasks. The design and size of a cofferdam will depend on the specific requirements of the project.

Synonyms

temporary dam, water barrier.

Examples of usage

  • The construction team installed a cofferdam to prevent water from entering the site.
  • A cofferdam was necessary for the repairs on the bridge's underwater foundations.
  • They used a steel cofferdam to create a dry workspace for the tunnel project.

Origin of 'cofferdam'

The term 'cofferdam' originates from the 16th century and is derived from the combination of 'coffer,' which means a box or chest, and 'dam,' which refers to a barrier built to hold back water. The word 'coffer' itself comes from the Middle French 'coffre,' suggesting a container. Historically, cofferdams were used by engineers and builders to facilitate works near or on water bodies by providing a dry area for construction. Their use has evolved over the centuries, particularly with advancements in engineering and materials. In modern construction, cofferdams can be found in various significant infrastructure projects, reflecting the continued reliance on this essential construction technique.
