LOCATION Hallett, South Australia 

CLIENT Ward Civil Engineering Pty Ltd 


– Structures 

North Brown Hill is one of the biggest wind farms in Australia at the time of construction, with the site located on private properties in rural South Australia and covering an expansive area of 38 square kilometers.

The project involved the construction of 63 turbines with a total installed capacity of 132MW.

The ground conditions specific to the site and remote location were drivers for an innovative rock anchored solution, resulting in significant cost savings through material and excavation reductions. Post-tensioning design techniques in conjunction with specialist geotechnical design, assisted in addressing the high loads and fatigue considerations associated with turbine foundation design.

The first power from North Brown Hill Wind Farm flowed into the South Australian electricity grid in August 2010.

CLIENT Twenty20 Energy Systems


– Civil 

Pacific Energy are delivering a 45MW gas fired turbine power plant for the MRDC. ADG was engaged to provide structural, civil and stormwater engineering services to support the project. In regard to structural engineering, ADG undertook design of all foundations and slab on ground including foundations associated with the gas turbines. All relevant PNG and applicable Australian Codes were considered inclusive of earthquake codes. Specific design considerations included the high live loads associated with the turbines on startup and developing a strategy for slab on ground which minimised slab thickness’s while ensuring sufficient set down areas for mobile cranes for ongoing maintenance.
Twenty20 required for all cabling to be located in accessible trenches below ground which ADG developed designs for belowground reinforced concrete cable trenches that were structurally adequate for all aboveground loading conditions.
For civil and stormwater engineering, ADG undertook detailed grading for the facility considering a number of factors including a thick layer of black soil and upstream catchment flows impacting the site. ADG’s earthworks strategy achieved an economical outcome through considering the layer of unsuitable black soil and graded the site to balance the earthworks cut to fill after removal of the black soil. To provide the site with high immunity against stormwater impacts of the upstream catchment, ADG’s strategy undertook calculations of the peak upstream stormwater flows and utilised the black soil as a bund to direct the stormwater flows around the site.

CLIENT Origin Energy Resources Ltd


– Civil

On the Origin Roads project, ADG optimised previously identified horizontal and vertical allignments for approximately 50kms of roads resulting in cut and fill balances for each km of the alignment. This was a design and construct contract where ADG were able to identify significant savings in the reference design for the contractor. On this project ADG utilised locally available material for road base and provided constructible options drastically reducing the amount of drainage infrastructure and imported fill required by constructing diversion bunding earthworks & independently grading table drains removing the need for some culverts as well as downsizing culverts after assessing time of closure and effect on upstream afflux level was deemed acceptable. This enabled us to provide a fit for purpose value for money outcome for the client.
Innovative drainage design was incorporated to combat heavily vegetated areas in which culverts were not suitable for installation.

ADG Engineers were in engaged to carry out the review of the earthworks filling for Stages 1 and 2 of the East Arm Wharf development. ADG were then engaged to carry out the site supervision of the filling and earthworks for stages 3 and 4 which are still in construction.
The review of the Stage 1 and 2 earthworks required ADG to review another consultant’s documentation to date, carry out site inspections, review geotechnical testing and provide advice on the current earthworks condition. To meet the land owners requirements and relevant geotechnical and earthworks specifications it was deemed that test pits in the existing fill were required to ensure the material placed on the site was deemed within specification for the site.
Upon receipt of testing and visual inspection by ADG Stage 1 and 2 were able to be certified and works could proceed on stage 3 and 4. ADG’s role in the current works in Stage 3 and 4 was to prepare a Quality Management Plan and testing regime to ensure the works meet the specifications.
ADG were faced with the challenge of taking on this project mid-way through the works with some conflict between the contractor, land owner and past consultant. ADG were able to thoroughly review all of the documentation and provide a way forward which met the needs of all stakeholders.
ADG have to date successfully carried out the scope of works for this project in assisting the Stage 1 and 2 to be certified and the continuation of the works for Stages 3 and 4.

CLIENT Northern Territory Government


– Civil

ADG was engaged by the Department of Infrastructure, Planning and Logistics to undertake the detailed design and documentation for the construction of the upgrading and sealing of a 3km section of Oenpelli Road adjacent Red Lily Lagoon.

The design encompassed lifting the existing road surface, installing relief drainage and providing a sealed surface in accordance with the NTG standard cross-section profile for rural roads.

The main objective was to:
– Improve road safety and ride quality;
– Improve flood immunity and road drainage;
– Minimise vehicle weight and type restrictions due to existing flooding/pavement

Preservation issues;
– Protect adjacent sacred sites from dust and any damage;
– Improve access for the remote communities.

As part of the detailed design for this project, ADG modelled the local flood event using a comprehensive 2D XP-STORM Hydrologic and Hydraulic model. Flood models were generated for the existing and post-upgrade scenarios and modelled for storm events up to and including the Probable Maximum Flood (PMF). Through modelling the existing flood scenario.

ADG was able to identify locations requiring relief drainage and the magnitude of flood inundation across the existing road surface. Post upgrade flood modelling was undertaken to demonstrate the proposed upgrades achieved the objective of improving floor immunity and road drainage.


LOCATION Groote Eylandt, Northern Territory

CLIENT Anindilyakwa Royalties Aboriginal Corporation


– Civil

The project comprised of the civil design to support the development of Pole 7 on Groote Eylandt which provided 16 residential allotments, a worker’s camp and warehouse for use by the Anindilyakwa Land Council. ADG provided complete civil design, tendered the project for construction and was Superintendent throughout the construction phase.

The project was located within an area outside service authority jurisdictions. Construction quality was managed closely throughout the project to ensure a high-quality product in accordance with all relevant Australian Standards and Guidelines were completed. The remoteness of the project also meant local site materials were being used which meant designs had to be suitable for use of natural materials.

Being in such a remote location, the cost of materials to complete the works were significant. ADG worked with the contractor to provide smart design solutions to minimise costs while still delivering a high-quality product that met the design brief.

– Construction Services 

ADG was engaged to provide the civil design (earthworks, pavements, stormwater drainage and footpaths), structural and temporary works design of the electrical substation.

The site was contaminated with asbestos and thus a capping layer had to be placed over the site to make it safe for living. As the existing soil was contaminated with asbestos, trenching and excavation within the existing soil was a costly and slow exercise.
ADG provided unique design solutions for stormwater to minimise the inground infrastructure saving the client time with construction programme and significant cost reductions for minimal trenching works within asbestos contaminated material.

ADG civil design helped the client to excel the construction well ahead of program and finish the project on budget and ahead of schedule.


LOCATION Point Stuart, Northern Territory 

CLIENT Northern Territory Government


– Civil 

ADG Engineers (Aust.) Pty Ltd have been engaged by The Northern Territory Government Department of Infrastructure, Planning and Logistics (DIPL) on behalf of the Department of Primary Industry and Resources (DPIR) to provide survey, geotechnical investigation, and detailed design for the upgrading of a 30km length of Point Stuart Road from the end of the existing formed roadway to the boat ramp.
The existing road to Point Stuart was a single access track, which was inundated by flooding during the wet season. ADG were engaged to upgrade the road to a two (2) lane rural road and provide a design that improved access to the existing boat ramp during the Northern Territory wet season. The design required realigning 4km of the existing road to be within the surveyed cadastral boundaries and the upgrading of roads within existing pastoral lease areas which required land acquisition.
As part of the design of the road


upgrade, ADG completed detailed flood modelling to analyse the performance of the existing road and determine the magnitude of upgrades required. The stormwater modelling was used to inform and shape a design solution that provided flood free access to the existing properties and boat ramp during the wet season.
Through the detailed flood modelling completed, ADG were able to optimise the earthworks design to minimise the requirements for imported fill, providing significant cost savings for the project.
There were areas of cultural significance in the area of the proposed upgrade works and ADG had to develop design solutions that promoted a safe driving environment without ant disturbance to the existing road within the defined Restricted Works Areas.
ADG worked collaboratively with the client and stakeholders to provide a design that provided access throughout the wet season and significantly improved the safety of the road environment.
