KINSELLA’S ROAD EAST - MORETON BAY RAIL LINK, $1M
MCILWAIN CIVIL
As part of the Department of Transport and Main Roads’
Moreton Bay Rail Link project, AllenCon was engaged
as a specialist subcontractor to the principal contractor
(McIlwain Civil) to undertake the construction of a three
span road-over-rail bridge and pedestrian path.
The high profile project was delivered as the first package
on the future rail ink project and saw AllenCon undertake
all formwork, reinforcing and concrete requirements for the
bridge which included:
• Sub-structure pilecaps with a concrete volume of 340m3
• Abutments with 4.5m high wingwalls
• Two blade piers measuring 15m wide x 10m high
AllenCon also provided site cranage and supervision of the
placement of 21 x 1,525mm deep Super-Tee girders.
The super-structure works extended from deck pours,
placement of PC parapets and facing pours, to the
installation of both underslung deck drainage pipework and
anti-throw screens.
As a result of AllenCon’s extensive bridge building
experience and successful track record in delivering road
over rail structures, the company was responsible for the
design of all formwork and it’s certification on this project.
To ensure seamless integration with the principal
contractor’s program, AllenCon was involved in all aspects
of project staging including the planning of temporary
earthworks and hardstands. This collaboration resulted in
streamlining the employment of machinery across the work
site to ensure the most efficient use of site plant.

BURPENGARY CREEK CYCLE BRIDGE, $450,000
MORETON BAY REGIONAL COUNCIL
As part of it’s commitment to local safety and
community accessibility, Moreton Bay Regional
Council awarded AllenCon the construction
contract to build a 35m single-span bridge over
the Burpengary Creek. The new bridge is just
one section of an extensive pathway linking
Naranbga and Burpengary with Morayfield and
Caboolture.
The pedestrian and cycle bridge was completed
both on time and budget and has been certified
as Disability Discrimination Act compliant.
The 35m steel truss span was fabricated in one
section off-site, prior to its transportation to a
specialist subcontractor – South Pacific Marine,
Burpengary – where specialist painting and
surface treatment was undertaken for anti-
corrosion.
Following treatment, the truss was then delivered
to site at night by low loader for installation
under temporary road closure. In order to meet
AllenCon’s high safety standards, a dual crane
lift method was used to manage both the size
and weight of the truss and to ensure it’s exact
placement on the support structure.
The location of the site, adjacent Oakey Flat Road,
necessitated that final installation of the truss be
carried out at night, under strict traffic controls,
thereby avoiding impact to local daytime road
users.
As part of the design specifications, and in order to
minimise deliveries to site and therefore disruption
to the local community, the bridge deck – a
reinforced concrete topping slab – was a cast
insitu and set over pretensioned concrete deck
panels that were fabricated off-site. The reinforced
concrete abutments sit atop 600mm dia piles that
were also cast insitu.
The completion of this bridge allows the safe
movement of many school children, recreational
pedestrians and cyclists along Oakey Flat Road.

11. PROJECTS HOME
AllenCon was awarded this project by Moreton Bay Regional Council – a repeat-
business client – to construct a 60m, four-span pedestrian and cycle bridge to replace
the original creek crossing that had been subjected to regular flooding.
The location of the project necessitated a unique design approach to ensure that the
structure blended into its natural surroundings as much as possible. AllenCon utilised 220
precast concrete planks that simulate the effect of a timber boardwalk and therefore
minimised any negative aesthetic impact of the bridge.
The main span over the creek is a 16 Tonne steel truss, which was fabricated in 9
separate sections to allow for the galvanizing process to take place. To combat
the restrictive access and poor ground conditions on the site, these sections were
assembled and launched into position across the creek on temporary falsework and
industrial skates.
The bridge consists of five reinforced concrete pier/abutments placed on piles cast
insitu ranging from 750 - 950mm diameter. The sub-structure pilecaps have a concrete
volume of 340m3
and each of the three approach spans comprise twin 610mm
Universal Beams.
The bridge was constructed to full Disability Discrimination Act compliance and now
enables both pedestrians and the local cycling community to cross Lagoon Creek
safely and securely year round regardless of weather conditions.

The Pinkenba Common User Terminal at the Port of
Brisbane is primarily used as a berth for grain, fertiliser and
fuel vessels. As a secondary function it provides a storage
facility for clinker (an element of cement), a holding
enclosure for livestock and a workshop for carrying out
vessel repairs.
As part of the upgrade works to the terminal, AllenCon
was responsible for the demolition of two, double-
storey brickwork structures. An element of these works
necessitated the removal and disposal of materials
containing a significant amount of Asbestos. All work was
carried out with strict client/stakeholder consultation and
in accordance with all legislative requirements.
Following demolition, works were undertaken to
rehabilitate the unsuitable subgrade prior to construction
of a new heavy-duty pavement.
Other project works included installation of services
such as lighting, water, power reticulation and septic
connections for the incoming new demountable
buildings.

During heavy rains in December 2010, a significant
failure of the approach embankment to the Newport
Bridge on Griffith Road occurred. In order to repair this
breakdown, and to mitigate any future occurrence,
Moreton Bay Regional Council initially installed sheet
piles to arrest further erosion and AllenCon was
engaged to construct the permanent works design.
Construction began in April 2011 with the excavation
of the saturated plastic clays and preparation of
the work site including soil nailing and shotcreting to
temporary excavations. In order to provide a suitable
working zone, an all-weather piling rig was established
on the unstable slope to enable safe installation of 150
pre-cast piles.
As part of this flood repair project, an 80m long pile
cap was cast insitu and the construction of the
concrete wall, revetment walls and ‘ConCrib’ retaining
walls were undertaken. This product was selected due
to its open web construction and use of free draining
material that provide both long-term durability and a
resistance to rotting or warping.
The proximity of the site to the heavily utilised road
required the implementation of extensive traffic
management procedures. The works were undertaken
directly adjacent to the Newport Marina and Griffith
Road where the existing road shoulder surfacing, kerb
and channel were also replaced. AllenCon carried
out contra-flow traffic measures on the opposing side
of the median in collaboration with the Queensland
Police, local authorities and executed the works under
all necessary work permits.
Provisions for bus and heavy goods vehicle movements
were also undertaken together with pedestrian
management and detours.
Despite experiencing a slow start due to poor
weather and bad ground conditions, the project was
completed on-time, within budget and with minimal
disruption to the local community.

monitoring of stability and condition as required, in
order to complete the works within the scheduled
programme.
BIBIMULYA STREET DRAIN RENEWAL, $250,000
MORETON BAY REGIONAL COUNCIL

16. PROJECTS HOME
The small township of Dayboro, situated north-west of
Brisbane, was established in the late 1800’s and is a
popular tourist destination. The community has expanded
over the years but the town centre still boasts historic
stores including a butchers shop, post office, former bank
building, and the Crown Hotel. However, the centre’s
susceptibility to flash-flooding has caused serious impact
on daily life for local residents and business owners
alike.
In a bid to find a solution to this issue, AllenCon was
engaged by the local council to undertake the removal
and replacement of existing drainage culverts in the
town centre and therefore provide an answer to the
problem.
The close proximity of local businesses to the work site
required some unconventional staging with the upstream
portion of the culverts being constructed first. This method
required extensive weather-proofing to the exposed
excavation – the remaining road embankment – so that
Williams Street would not be subjected to any erosion
should there be a storm event during construction.
The location of the works also necessitated significant
traffic control measures that were implemented using
single lane/traffic light controls with half of the works
completed initially, and the remainder completed
following the traffic switch.
In keeping with the look and feel of the historic township,
the exposed concrete surfaces of the headwalls and wing
walls were clad with recycled hardwood resulting in the
appearance akin to an old timber bridge.
With significant clearing and landscaping undertaken and
the installation of new pedestrian paths the area remains
an attractive stopping point for tourists and locals.
The project was completed by AllenCon to the full
satisfaction of the client and stakeholders alike.

Using our highly experienced supervisors, plant operators and skilled
labour force, AllenCon self-performed all of the works comprising
the Wharf 11 stormwater drainage project.
These works included laying 377Lm of twin 1,500mm diameter Class
4 marine-cover RC pipes and the construction and installation
of seven reinforced concrete access chambers. Each chamber
was approximately 4.5m deep, 6m wide and was cast insitu. The
chambers were installed along the pipeline and included blockouts
for the future connection of shallow, small diameter drainage
pipes.
Due to the poor ground conditions it was necessary to remove
unsuitable material such as marine muds and silts, and replace
these with insitu white sand. This allowed the pipes to be laid on a
stable and compacted base of homogeneous white sand.
All of the above works were constructed below the water table
using a combination of conventional sump pumping and spear
pump dewatering techniques.

PORT OF BRISBANE LTD
drainagE
18. PROJECTS HOME
The project involved the casting of a 400mm
deep reinforced concrete slab under the
existing soffit of an operational stormwater
culvert. The casting was undertaken on site
and was complicated by the tide-affected
nature of the project’s location – on the shore
at Redcliffe, north of Brisbane.
The works were originally deemed ‘confined
space’ due to the limited amount of free-
movement area within the culvert. Following
the slab casting, the clearance distance was
increased to 1.5m and the project was re-
classified as ‘restricted access’.
The project presented several issues that
affected formation of the slab, prompting
AllenCon to develop an alternative
construction method. As an option to the
proposed design method – requiring the
placement of concrete from road-level above
the culvert – AllenCon proposed to form and
pour the concrete from within the culvert.
The client welcomed this innovative approach
and, as a direct result of AllenCon’s forward
thinking, achieved significant time and cost
savings.
The project was completed two weeks ahead
of schedule despite experiencing delays due
to storm events and tidal surges.
