Muddy Gates – Temporary Cofferdam

Cerecon was tasked with designing a temporary cofferdam as a vital component of the Muddy Gates culvert upgrade project near Tooradin. With existing culverts to be relined within a tidal zone, we devised a movable cofferdam to make the work possible.

Our solution was a steel-framed box fixed to the culvert’s headwall, sealing it against water intrusion. To counteract buoyancy, we added concrete counterweights on an external shelf, preventing flotation of the cofferdam and enabling effective water management throughout the works.

The design also allowed the culvert to remain partially open during the works. This simplified the setup and avoided the need for expensive pump systems.

Cerecon’s movable cofferdam shows how we combine structural engineering expertise with practical adaptability to solve complex site challenges efficiently and precisely.
