Pre-cast reinforced concrete panels were also installed over the front of the wall superstructure to provide an architecturally acceptable finish.

The retaining wall construction sequence was carefully designed and staged to control ground

movements and groundwater drawdown, and, minimise the risk of damage to adjacent roads and buildings.

Proposed Tioman Airport Runway Extension, Tioman Island, Malaysia (2002).

Feasibility study of the proposed extension to an existing 990m long runway.

The purpose of the proposed runway extension was to enable larger and/or more modern turbo-prop aircraft, such as the 70-seat Bombardier Dash 8 Q400 and the 50-seat Fokker F50, to operate from the existing airport facility.

An extension of the existing runway would require a large volume of granite rock to be excavated from the southern end of the site. Issues associated with the site topography, the aircraft approach paths, safety and cost made the option of extending this runway highly unattractive, and, the better option of identifying a new airport site was pursued.

St Louis City Justice Centre St Louis, Missouri, USA (2000)

The St Louis City Justice Centre is a multi-story building with a 30-foot deep basement excavation. The site is located adjacent to historic buildings and an arterial road.

Martha Mine Settlement Study, Waihi, New Zealand (1995 - 1997)

The Martha Mine incorporates a large open-cast pit located within the town limits of Waihi. Excavation and dewatering of the Martha Pit had the potential to cause settlement of the

surrounding ground surface due to a combination of ground relaxation and depressurisation.

During 1995 the mine operator commissioned a geotechnical study to assess the ground movements which had occurred due to excavation of the Martha Pit and predict the magnitude of settlement which was likely to occur in the future due to completion of the currently consented excavation. This study also included an assessment of the magnitude of additional settlement which was expected to occur if the depth and/or extent of the pit were increased.

On this project Anthony was responsible for management and documentation of the geotechnical investigations and detailed engineering assessment of settlement. This assessment included the development of several 2D finite element models using the software package “Plaxis”.

A report summarising the above work was submitted in support of the 1997 resource consent application to increase the plan extent and depth of the Martha Pit.

Geotechnical Instrumentation Review and Maintenance Programme, Martha Mine, Waihi, New Zealand (1998).

The Martha geotechnical monitoring programme includes over 230 survey marks and 100 piezometers to measure changes to the ground and ground water levels within the township of Waihi.

An audit of the monitoring results indicated the procedures, instrument installations and master database should be collated, checked and corrected, as appropriate, to ensure accurate monitoring reports were compiled and issued.

As a result of the above audit the mine operator commissioned a maintenance programme to

ensure all instrument installations were functioning as intended, reliable results were being consistently obtained, the monitoring programme was fulfilling its primary objectives, and, the all of the consent conditions were being met. This maintenance programme included an inspection of all monitoring installations, flushing of blocked standpipe piezometers, correction and updating of the digital databases, the generation of accurate summary plots, and, the creation of an integrated geotechnical monitoring plan.

On this project Anthony was responsible for all field and maintenance works, database review and correction, writing of the monitoring plan, and, writing of the 1996 and 1997 annual monitoring reports.

Thorburn’s Gully Overburden Fill Site, Stevenson’s Resources Drury Quarry, Papakura, South Auckland (2008 - 2009)

assessment identified this movement occurred on an existing shear surface in the foundation soils and slope movement was activated during times of high rainfall / groundwater pressure.

On this project Anthony was senior geotechnical engineer responsible for identifying the likely cause of the ground movement, recommendations for emergency works, and, options assessment, detailed design and construction certification of the permanent stabilisation works.

The works comprised construction of groundwater controls and an engineered fill shear key.

This project comprised the proposed construction of a new haul road to enable 50 million cubic metres of overburden material to be transported from the Awaroa 4 Pit to the Township Pit for use as backfill material.

The proposed haul road had an initial length of approximately 850 metres and was designed to be extended in the future as the Awaroa 4 pit advanced.

Fill embankments up to 16 metres high and a new multi-plate super-span tunnel structure were proposed to enable the new haul road to pass alongside the Awaroa 3 Pit and cross over an existing public road.

The design vehicle for the new haul road comprised Komatsu 730E dump trucks with a maximum laden weight of 362 tonnes.

On this project Anthony was the T&T project manager & geotechnical/civil engineer responsible for the haul road and embankment design.
