How Much Does a Cofferdam Cost?
Cofferdam cost varies, and there is no simple answer to the question, “How much does a cofferdam cost?” The cost depends on many factors, including size and transportation costs.
More important, is the question only about the cofferdam itself? Or, rather, the cost of a temporary cofferdam system? There is a big difference between the two.
The base cost of a temporary cofferdam depends on three factors – length, width and height. If you know the dimensions of the cofferdam(s) your project requires, call us for a free cofferdam cost estimate. (Note: When estimating the total cost of a cofferdam, be sure to factor in transportation.)
A cofferdam system includes the cofferdam itself, in addition to all labor and materials needed to install, monitor, maintain and remove the system. The size and duration of the projects vary tremendously, and therefore, the costs associated will vary as well.
Selecting a contractor (or contractors) to manufacture and install a temporary cofferdam to meet your specific needs is one of the most important decisions you will make to ensure the success of the project.
There are several factors to be considered in cofferdam cost:
- Number of Contractors
- Cofferdam Size
- Who will provide the following equipment that is recommended for cofferdam installations?
- Project Personnel
- Who will be responsible for provide the following project personnel?
In Stationary Water
Two to four workers are typically required to install small (less than 4 feet in height) cofferdams in stationary water.
Three to six workers are typically required to install large (4 feet or higher) cofferdams in stationary water. Ropes are usually not needed but can be used to maneuver the cofferdam in deep water depths.
In Moving Water
Three to seven workers are required to install small and large cofferdams in moving water.
Please refer to the chart below for the personnel requirements and their effect on cofferdam cost:

Workers in the Water
Workers Manning Pumps
Note: Strong water currents require more personnel to ensure proper installation and the safety of all workers.
Adding the cost of each item, in addition to any contingency amount for conditions beyond your control, such as weather, will be a good indicator of the cost of your cofferdam system.
