Underground Electricity
Our specialist underground
crews bring their expertise to
the construction and installation
of permanent and temporary
underground electricity
supply. Our cable layers and
jointers ensure transformers
and switchgear, cable hauling
and jointing, and sheath and
continuity testing, are installed
to exacting standards and comply
with all statutory and network
owner requirements.
We provide high and low voltage
underground electricity supply
projects from North Queensland
to Victoria and Western Australia.
We draw on our civil capabilities
in directional drilling when
required to accommodate road
and rail crossings or minimise
surface disturbance.
During the construction of Brisbane’s
$4.8 billion Airport Link Project,
we undertook all of the temporary
electrical works required to energise
this project’s multiple, heavy
equipment-intensive work sites.
(Left) The Airport Link team
relocated numerous overhead
lines and underground
electricity and gas services.
In the three-and-a-half-year
construction period, the team
installed 53.6 kilometres of
conduit, 10 kilometres of high
voltage cable, 7.3 kilometres
of low voltage cable and 75 pits.
TRANSMISSION infrastructure
Thiess’ services business is strengthening its
engineering and construction capability to deliver
substations, transmission lines, underground cable
projects and high voltage services. We bring the
systems, engineering and construction capabilities
of the broader Thiess group to these projects.
Mining and Industrial High Voltage Services
As one of Australia’s leading construction,
mining and services contractors, the
Thiess group has the expertise and
experience to deliver integrated project
solutions. Thiess’ services business
provides the specialist brownfield civil,
water and electricity infrastructure
construction and maintenance services.
On site we draw on a team of specialists
across civil, structural, electrical
installation and protection testing
works. Our teams are highly mobile and
experienced in working in challenging
locations. They construct to precise
specifications while managing schedules,
logistics and quality assurance
processes. They also have access to
an extensive range of specialist plant
including elevated platforms, cranes
and specialist transmission lines
stringing plant that complies with
strict mine specifications.

(Below) AquaSure contracted Thiess Degrémont to design and
construct the $3.5 billion Victorian Desalination Project. Part of the
work involved the design and construction of two electrical substations
to maintain a steady and reliable flow of power to the desalination
plant, smoothing out any surges or drops in voltage. The team also
built a third GIS 220/22 kV substation to power the desalination plant.
Substations and Transmission Lines
Delivering high voltage substations
and transmission line projects requires
multi-discipline capability and the
organisational ability to assemble and
project manage a team of designers,
equipment suppliers, planners, field
engineers, skilled construction and
electrical workers, and linesmen.
We team with specialist design partners to
deliver underground cable, substation and
transmission line projects at voltages up
to 330kV. Our partners are selected on the
basis of their niche skills and knowledge in
particular sector areas. To ensure optimal
results, we assign a design manager with
construction experience to lead and
challenge design concepts at the outset.
Our team can work with clients under
a traditional ‘free issue’ project material
approach or offer alternative product
supply and technology. We have key
partnering arrangements in place with
specific overseas manufacturers that
give us access to quality transmission
line structures, conductors and
componentry, high voltage cables,
substation transformers, switchgear
and secondary systems.
We leverage the
engineering and
construction capabilities
of the Thiess group.
Increasing electricity prices, the need for a reliable
energy supply and the push for reduced greenhouse
gas emissions are driving the commercial demand
for smart services. This multi-layered approach to
developing smart network solutions is delivering
lower costs, a variety of delivery choices and a
sustainable, lower carbon future .

In Focus
Mining region boost
We constructed and energised a new 132kV
tie line between the existing substation
at Isaac Plains and the new substation at
Broadlea in Central Queensland for Ergon
Energy. Initially insulated at 66kV, the line
is approximately 4.3 kilometres in length
and supported by 35 pole structures
varying in height from 12.5 to 38 metres.
The scope of work also included
installing new 132kV line entries into
the Broadlea and the existing Moranbah
substations; erecting new poles for the
55-metre landing spans at Broadlea
substation for the Moorvale and
Carborough 66kV feeders; and stringing
about 14 kilometres of optical ground
wire in an ‘underslung’ arrangement.
At locations with inadequate clearance,
the team installed the fibre optic
connection underneath a Queensland Rail
crossing using trenching and horizontal
boring techniques.
Proven gas capability
Thiess’ services business entered
the natural gas distribution sector
in 2000 when we secured an
operations and maintenance
contract for the south and east
areas of Melbourne with Multinet
Gas Distribution. We were
responsible for more than 8,500
kilometres of distribution pipe,
120 kilometres of transmission
pipelines and more than 220
pressure regulators feeding more
than 550,000 domestic, commercial
and industrial customers.
The contract services included
first and emergency response,
mains and services maintenance
and repair, systems operations,
cathodic protection, pipeline patrol
and associated works to ensure the
gas distribution network operated
in a safe and reliable manner.
Our business grew when we
acquired Champ Constructions,
a medium-sized gas construction
contractor predominantly
servicing the south and south
eastern regions of Melbourne
and the Mornington Peninsula.
We currently provide mains
and services construction, and
renewal services, for the three
Victorian networks owned by
SP AusNet, Multinet Gas
Distribution and Envestra.
relationships with
global energy
equipment providers
enable us to realise
new value and
minimise risk.
A Healthy Injection
As part of the $756 million
redevelopment project at Sydney’s
Royal North Shore Hospital,
Thiess’ construction and services
businesses installed two 2MW
cogeneration facilities to meet
the base load energy demand of
the new hospital, in addition to
two 2MW diesel generators for
emergency purposes.
The heat recovered from the
cogeneration facilities is being
used to provide domestic
hot water and heating for the
hospital. Fully operational, Thiess’
services business is currently
responsible for the operations and
maintenance of the cogeneration
facilities for a 28-year period.
Thiess’ scope included:
»» Feasibility studies during
tender stage to validate
the viability of the
cogeneration facility
»» Financial modelling to
determine optimum plant
size and pay back periods,
and operations and
maintenance costings
»» Preparation of detailed
»» Tendering and tender
»» Management of
construction contracts.
