Challenges and achievement

Working within limited times restrictive and share spaces. Deep excavations and high-risk lifts around other constructions, subcontractors, structures, movement around site., crossing of an 11kV electrical easement, unknown underground pipework, and electrical cables.

Fruitful workshops, effective team effort in relation to risk management planning for Major 4hr limited shutdowns for cut-in, connections, bypassing, diversion including nighttime works.

Satisfactorily completion of all works without incidents or disruption to the treatment plant or breaches to its EPA license.
