Eastern Creek Sewer Main

Project Type

Construction

Location

Sydney, New South Wales

Services Provided

Shoring

Challenge

Excavating four pits to depths between 12m and 17m through soft soil and rock to allow a boring machine to come through enabling the installation of a sewer main which runs under a main road.

Solution

Three levels of four sided 7m Aluminium Shoring lining the top section of each pit were used and then four sided 6m Heavy Duty Steel Shoring was used below allowing the use of a small excavator to dig in the bottom of each pit.  Specialised ladders were constructed allowing access for workers to the bottom of the trench with Davit Arms.

Result

A very safe and neat excavation in all pits with plenty of working room at both the top and bottom.
