Increased Tension Pile capacity and reduced the number of Tension Piles
Key Stages of Cofferdam Installation Works
Shinei Geotechnique was engaged in the Design and Construction of a large circular Cofferdam for the Inlet Works of the Regional Standard Treament Plant, Package 2, Ipoh. The Cofferdam is of diameter 49.0 meters and for excavation down to a depth of 21.0 meters. This is currently the largest cofferdam ever constructed in the Country and is located in a very complex limestone formation in Papan, Perak.
We are very fortunate to have Shinei's vast experience in handling the work with highly skilled technical input, coupled with their extended work safety culture in this extremely difficult work site.
The works have been recently completed in time and to our greatest satisfaction.
We are very appreciative of Shinei's contribution and deserves our strong recommendation to the other clients for difficult and complex ground engineering works.
