SOUTHERN PRECINCT OF MANDURAH OCEAN MARINA, MANDURAH, WESTERN AUSTRALIA

Project managed the construction of the southern precinct of the Mandurah Ocean Marina. The construction work involved construction of a dewatering bund around the sea side of the marina, dewatering the internal part of the marina in sections using large capacity pumps, removing weak ground, preparing foundations for mechanically stabilized seawalls and backfilling the seawalls. A number of bridges were also constructed to provide access to the marina. My role included observing and approving excavation of soft soils from the base of the marina, preparation of mechanically stabilized seawall foundations, preparation of bridge foundations and backfilling behind the seawalls.

Investigations were also conducted during the construction to better delineate subsurface conditions where little investigation was available or where unusual subsurface conditions were noted and to confirm that the design was appropriate.

Following completion of the project several geotechnical investigations were conducted for multi storey buildings up to 9 stories high to be located on lots adjacent to the seawalls. These projects required an assessment of the subsurface conditions, foundation and stability analyses, provision of advice on dewatering and earthworks and preparation of reports. In almost all cases, pile footings were required for the portions of buildings closest to the seawall.

INNER HARBOUR, PORT OF BUNBURY, BUNBURY, WESTERN AUSTRALIA

Conducted geotechnical studies for minerals sands storage sheds for Cable Sands and BHP to be located in reclaimed areas immediately behind the wharf structures. The fieldwork comprised cone penetration testing across each of the sites. Office based work comprised, foundation analysis, provision of recommendations on suitable footings and earthworks and preparation of reports.

BANDY CREEK HARBOUR, ESPERANCE, WESTERN AUSTRALIA

Involved in geotechnical studies for the Bandy Creek Fisherman’s Harbour and provided geotechnical advice during construction. Subsurface conditions comprised sands and the harbour was built in the dry by construction of a bund across its entrance into the ocean and a concrete weir across a narrow section of Bandy Creek immediately upstream of the harbour. The area was dewatered using a large pump located in a sump at the upstream toe of the bund.

Excavation was achieved using scrapers and wharfs and other infrastructure items were constructed in the dry. Once the works had been completed, the bund was breached and seawater allowed to fill the harbor. The concrete dam maintains fresh water within Bandy Creek.
