Solid Energy, Huntly (2005).
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.
 Federal Route 1, Seremban to Gemas
Malaysia (2002).
On this project Anthony was the Senior
Geotechnical Engineer responsible for structural
evaluation of 94 kilometres of two-lane federal
highway. This project included a visual surface
condition survey; FWD testing, investigation cores
through the pavement surface, test pits, in-situ
CBR testing, and pavement rehabilitation analysis
and design.
 Cyclone Dani Repair Works,
Bauerfield International Airport,
Port Vila, Vanuatu (2000/2002)
During 1999 severe tropical storm Dani
caused extensive scour and erosion damage to
the river bank immediately adjacent to the
northern end of the main runway. For this
project Anthony was responsible for detailed
design of the repair works which comprised a
230-metre long by 4.5-metre high reinforced
earth and gabion basket retaining wall, Reno
mattress scour protection, stormwater outfall
structures, and, reinstatement of the airport
perimeter road and security fence.
 Auckland Airport Eastern Link
Puhinui Stream Crossing,
Manukau City, Auckland, New Zealand (1996)
Geotechnical engineer responsible for the
engineering analysis and construction
supervision of manchette grouting works at
the toe of existing large-diameter bridge piles
to mitigate settlement.
During construction these bridge piles
exhibited an undesirable amount of vertical
settlement during launching of the bridge
deck structure. Tony was part of the design
team who investigated, designed and
supervised the post-construction pile toe
grouting remediation works to limit future
settlement to acceptable levels.
 Miscellaneous Residential Developments
Nelson Region, (Ongoing)
Over the past 5 years Anthony has provided senior
engineering support to the T&T Nelson office. In
this role he has been directly involved in the design
and/or construction certification of numerous
earthworks and retaining wall projects including:
- Tied-back timber pole retaining walls.
- Cantilever steel pole retaining walls.
- Cantilevered timber pole retaining walls..
- Remediation of failed retaining walls (designed by
others).

14.  Rock Fall Remediation Works
Glenorchy – Queenstown Road (2010).
On this project Anthony acted as the lead
Geotechnical Engineer for the investigation,
options assessment, detailed design and
construction certification of works to stabilise three
blocks of schist rock that were assessed to be at risk
of falling on to the road below. The remediation
works comprised scaling to remove small loose
fragments and the installation of rock bolts and
shotcrete.
 Assessment of Ground Settlement,
Gilmore Property, Waihi (1996).
This project comprised investigation, assessment
and reporting as to the likely cause of ground
settlement on a property in Waihi Township.
The property owner claimed that parts of her site
had settled by up to 1.0m over the previous 3 years.
Geotechnical monitoring and engineering
assessment confirmed the magnitude of ground
settlement was significantly less than that claimed
and the settlement which had occurred was
primarily due to reasons other than the present-
day mine activities.
