A Cofferdam is one of the best watertight structures specially designed to help construction projects and buildings in a particular region that are usually submerged, like piers and bridges. With exclusive features, the excellent construction permits workers to enact repairs, build structural supports and perform some other jobs in a hassle-free and dry environment. If the construction is not installed properly, then it may create more hazards to the workers. In order to avoid dangerous issues, engineering advancements create a unique work setting and protect the workers properly.
There are several kinds of materials used to create a cofferdam. It is a temporary structure, but it has the capability to hold water back from the particular work area. Along with this, it also has specialized features to withstand greater pressure. The basic cofferdam utilizes sheet metal in order to create an effective watertight wall which can be very expensive and time consuming to install. Other types are built from concrete or wood and other prefer double walled techniques along with filler. There is a wide array of cofferdam constructions available including braced, rockfill, double wall, earth embankment, cantilever sheet pile and cellular cofferdams.

Cofferdams are a very effective way to provide dewatering solutions for a number of different projects. They can be utilized for construction sites, shoreline restoration projects, building bridges, and much more.
Each project’s specifications are extremely individual and can often change depending on the time of year and location. The experts at Water World, an influential online flood control industry news site, have provided 5 important aspects to consider when you begin your dewatering and cofferdam projects:
1. Depth and Flow
These conditions change from season to season. Water World suggests reviewing the timing of the project and consulting the U.S. Geological Survey (USGS) to gauge fluctuations in water levels at the site to determine the best timetable for the project.
“Turbidity requirements, contamination concerns, right-of-way restrictions, and time constraints for working in the water” are all items that may need permits or permission to conduct construction. Even though it is usually the responsibility of the project engineer to understand and obtain these permits, it is important for the contractor to know these as well.
3. Navigating the Subsurface
Water world suggests that knowing, “the silt levels, slopes, vegetation and composition of the subsurface” to determine the best cofferdam technology and specifications to meet the projects needs.
4. Contractor Experience
Because of the complexity of dewatering projects, it is important to hire contractors who have experience working in and around water. Experience affords the contractor the ability to understand and respond to changing conditions of the work site. They may have come across overlapping aspects in previous jobs to determine the best solutions for the current project.
5. Engineering and Design Criteria
The last aspect a contractor needs to know before beginning the dewatering project is the right cofferdam technology for the project and if the cofferdam’s construction cost meets specifications. “Further, he or she should conclude if the project calls for Professional Engineer Stamped Calculations. The contractor should be well-versed in dam safety protocol and standard operating procedures and also able to provide engineering support in an emergency.”
Understanding and utilizing each of these five tips can better prepare your project for a quick and efficient delivery. Hydrological Solutions is highly experience in dewatering projects, and understands the uniqueness of each site and the necessary processes for effective cofferdam installation.
There are a variety of cofferdam formations for different project requirements.
Repairs and construction can be very time consuming and expensive. You have to factor in the materials, time, and labor that produce the best results. When a project worksite requires a dewatering process, it is important to consider factors such as ease of installation and removal, labor requirements, and effectiveness.
The Aqua Barrier Cofferdam provides the best of all three. The ease of use and installation allows you to commence your projects in a timely manner without delay. Each worksite is extremely different, and considering a cofferdam for your project requires many details and specifications to be met. The Aqua Barrier Cofferdam is extremely versatile in its design and can be used for multiple projects and worksites given the variety of available formations. Each formation provides the most effective water and flood control based on the worksite requirements. Below is a list of the different formations and protection that cofferdams can provide:
Complete Enclosure Formation
A complete enclosure formation is beneficial when access to the shoreline is difficult or when a large amount of linear footage is required to reach your work area in the water.
Partial Block Formation
When projects are located in moving water, a partial block formation can be the best option for a cofferdam design. Since it is not feasible to use a pip diversion or a water pump to maintain upstream water levels, the Partial Block formation of a cofferdam can be the most viable option for dewatering your construction or building site.
Canal Block Formation
A Canal Block Formation is beneficial when working in narrow channels because the system requires only one installation and removal. Water pumps can be utilized to maintain appropriate upstream water levels.
Straight Shoreline Formation
A Straight Shoreline Formation is best utilized when a work area is located in a recessed cove.
Entire Shoreline Enclosure Design
An entire shoreline enclosure design is useful when only one installation and removal is required in the work are.
Multiple Staging Configuration
Multiple Staging Configurations are beneficial when the scope of work involves a large expanse of shoreline because the barriers can be installed and removed in short order.
