Jack Hawken Lane, Silverdale

Jack Hawken is a Residential Sub-division with 100 lots adjacent to the Northern Motorway, Silverdale.

The site consists of rolling contour and requires counter-fort drainage to stabilise the under-fill substructure conditions.

Jack Hawken comprises 66,000 m³ of cut to fill, however there is an additional 40,000 m³ of unsuitable undercutting due to previous motorway works.

There is an active water course which requires a complex sediment control methodology to mitigate any discharge from site.  This is crucial since much of the works are being carried out during the winter months.

Earthworks commenced December 2015.
