Geotech was engaged as Principal Contractor by Orange City Council to increase Suma Park Dam’s storage capacity and make the dam compliant with dam safety standards. The construction of these works was carried out under asbestos conditions due to the dam being founded on naturally occurring asbestos rock. Part of the works required an obsolete earthen saddle dam to be upgraded with an auxiliary fuse plug structure. Geotech identified a risk that the fuse plug structure may affect structural performance in a flood event, and so proposed the design and construction an alternative concrete fuse gate structure – an approach that was approved by council. The concrete structure is able to be maintained and routinely tested to ensure its operational capabilities, providing security to the City of Orange.
