Bickford Terrace Major Drainage Project | The City of Holdfast Bay | Adelaide, SA | 2017-2018

The Bickford Terrace Major Drainage Project was an initiative of The Council in response to their Stormwater Management Plan and floodplain mapping which demonstrated that during an extreme weather event there was a risk to flooding in a number of areas within the suburb of Somerton Park.

After major ponding of stormwater occurred within Tarlton Street and Bickford Terrace, modelling showed that a major outfall was required to collect flows to substantially reduce the extent of flooding and prevent overflow of floodwaters further north.
Lucas TCS were awarded the contract by proposing micro tunnelling to install the 220m pipe instead of traditional open cut excavation construction techniques which would have been difficult to construct due to the depth required.

A large 83m long culvert (1.8m x 3.6m holding 530KL) detention/storage unit was constructed under the road of Bickford Terrace, designed to retain water during large weather events and then discharge to the beach.

Using a Guided Boring System over 220m of pipe was hydraulically jacked, in some areas 9m under ground level, to the precise line and level required.  This trenchless installation method ensured Lucas TCS achieved on-grade accuracy whilst eliminating some of the difficulties associated with open cut excavation.

By utilising trenchless technology, CO2 emissions for the project were cut by over 84% and continuous access to 30 properties was kept within a minimal construction footprint.

This project won a State and National CCF Earth Award and an IPWEA Award in 2018 for construction excellence.

The Mt Keith Haul Road is a 17km expansion project that is being constructed to develop a satellite mine to the main BHP Nickel West’s Mt Keith mining operation.

Lucas TCS were engaged by Qube Bulk to design and construct a 16.5km Haul Road with a 1.8m separation bund between the haul road and heavy mine vehicle access road.

The road needed to be of sufficient integrity to manage 6-wheel, 300 tonne mine trucks.

Works included:

• 15m wide heavy vehicle access track
• Heavy vehicle passing bays
• Drainage for the floodplains to handle sheet flow
• Floodways and culvert structures

Temporary water facilities for pumping and storage of construction water.

Works also included the cut and fill of over 180,000m3 of site won cut and fill material over the 17km roadway and with grade requirements of a maximum 3% for haul trucks with some cutting designed to exceed 7m on depth through hard rock material.

The project involved a detailed geotechnical investigation of the insitu soils and cut and fill materials, along with local rock sources for sub base and base course materials.

To assist the project, Lucas TCS produced our own sub base and base course onsite, crushing and screening over 200,000 tonnes.

Carrapateena Southern Access Road | OZ Minerals | Pernatty, SA | 2018-2019

Lucas TCS were awarded the contract by OZ Minerals for the localised upgrades of the Southern Access Road (SAR) at the Carrapateena Mine Site to accommodate over size and over mass vehicles.

The objective of this project was to improve safety at nine identified locations along the road, six on the public road section, and a further three on the private (OZM) section to Austroads and ARRB standards.

The improvements were specifically to enable A-Double vehicles to simultaneously pass one another while travelling in opposite directions at the nominated locations

The SAR is an unsealed road varying between 6-8.5m wide, and was generally formed below the surrounding natural surface level, particularly along the public road section, providing difficulties in terms of drainage of the road surface.

The scope also included using excavated material on site to build an embankment, in some locations up to 1.5m from the natural surface.

Works required pavement widening, provision of drainage swales, relocation of existing signage, and a full width overlay of a 200mm wearing course for the full extent of the works.

D&C Augusta, Eyre & Lincoln Highway Overtaking Lanes | DPTI | Whyalla, SA | 2018

In early 2018, Lucas TCS was awarded the D&C contract of three overtaking lanes and a junction upgrade on the Augusta, Eyre and Lincoln Highways to improve safety and increase efficiency.

Lucas TCS partnering with SMEC took the initial design from DPTI and by challenging the design requirements managed to optimise the design.

The scope of works included the following:

• Design and approvals of road geometry, traffic control devices, structures, drainage and environment
• Clearing and grubbing
• Topsoil strip and stockpile
• Sawcutting of existing pavement edges
• Cut and import to fill
• Shape and trim batters
• Supply and install culverts and headwalls
• Subgrade preparation
• Sub base and base course preparation
• Bituminous surfacing and sealing
• Traffic management
• Installation of road furniture and audio tactile line marking

One of the challenges was a lack of good pavement material so Lucas TCS selected, sourced and crushed over 46,500 tonnes from local borrow pits.

Lucas TCS completed the project with up to three work fronts working  simultaneously and also received approval for the use of a waste byproduct from the Whyalla Steel Mill which through testing was able to achieve certification of the material to a PM2/20 standard.

George Fisher Haul Road | Mt Isa Mines | Mt Isa, QLD | 2015-2016

In late 2015 early 2016, Lucas TCS successfully completed the reconstruction of a portion of the George Fisher Haul Road for Mount Isa Mines.

The scope of works involved profiling off the damaged seal over parts of the existing roadway, adding high CBR quarry products, mixing and placing these with binders to strengthening the pavement.

A 5km section of this roadway was then further resealed.

Work also included excavation of the Mullock Creek Crossing to a suitable level, followed by the placement of thick pavement slabs, edge protection and erosion control.

This project commenced directly after the completion of Glencore’s McNamara Haul Road Reconstruction, and Lucas TCS was sole sourced for the project due to our successful relationship on previous projects

McNamara Road Upgrade | Noranda Pacific/Lady Loretta | Mt Isa, QLD | 2015

Lucas TCS were required to build approximately 51km of new roadway to replace a dusty, ill formed access road which serviced two mine sites and local communities.

The project was on a gazetted indigenous reserve and had a requirement that all material for the road was to be sourced within 100m of the centreline.

Lucas TCS performed the following scope of works:

• Clear and grub and topsoil strip
• Survey and setout
• Establishment of borrow pits and pit extraction
• Material haulage, stockpiling, blending and conditioning of stockpile materials
• Crushing and screening
• Earthworks, subgrade preparation, trimming and compaction
• Road reconstruction, traffic management and diversion tracks
• Dust suppression
• Installation of culverts, shotcrete head walls and road furniture.

One of the largest challenges was the production of a suitable pavement material from the range of poor-quality bush gravel and soil and the requirement the base course should resist regular flooding.

Extensive testing was carried out with various stabilising agents including lime, cement, bitumen and a number of proprietary products.

Lucas TCS provided an engineering solution to use local materials and proposed the use of an innovative stabilising binder to reduce moisture ingress into the pavement, even during flooding, providing increased pavement strength.

Dugald River Mine Access Roads | MMG Limited | Mt Isa, QLD | 2013

Lucas TCS was engaged for construction of two Access Road contracts for the Dugald River Mine.

The first was the Main Access Road approximate 10 km in length and the second, running concurrently with the first was the Village Access road, approximately 3km in length through rocky and difficult terrain.

Construction also included an 80m bridge structure, multiple culvert crossings and a CASA specification Emergency Airstrip inbuilt into a widened section of the road.

The works were undertaken within an accelerated program and time frame due to the geographical location of the site, ensuring the works were completed before the onset of the wet season.

Lucas TCS worked closely with MMG Ltd and the Department of Transport and Main Roads (TMR) Queensland on the newly created Burke Development Road and Dugald River Access Road Intersection, to ensure the intersection was completed to TMR specifications, as well as with appropriate safety and traffic management on a critical path timeline.

Intersection works included road construction, line marking, stormwater diversions and road furniture.

The main access road was completed on time and within budget with no LTI’s, whilst maintaining access to the mine and other construction activities.

Osborne Mine Haul Road | Ivanhoe Australia | Selwyn, QLD | 2012

In 2012, Lucas TCS completed the construction of a 47km Haul Road for Ivanhoe Australia Limited, stretching from Mt Dore to Osborne, as part of the Osborne Mine.

The scope included clearing and grubbing, topsoil stripping, and the cut and fill of approximately 500,000m³ of site won material.

Also included in the scope of works was pavement construction, the construction of 50 culvert crossings and the Mort River crossing and the rehabilitation of areas impacted by construction activities.

Communications and logistics were challenging on the project due to the natural terrain and the remote nature of the project.

Considerable stretches of the road through very hard rocky outcrops required detailed drilling and blasting to achieve the road formation.

Halfway through the project, the mine changed ownership and the project involved a significant re-design and optimisation whilst under construction to facilitate redefined project objectives.

The project was completed both ahead of schedule and to the revised project budget.

Peculiar Knob Haul Road | Arrium | Near Coober Pedy, SA | 2011-2012

Lucas TCS were contracted to construct 97km of heavy haul road to service the Peculiar Knob mine site.

The road was required to withstand repeated heavy loads and was designed to handle the movement of 4Mtpa.

Lucas TCS cleared nearly 2,000,000m² of a heavily vegetated area for the infrastructure and roadworks and the road was constructed using onsite materials and approximately 300,000m³ of cut and fill earthworks to form the alignment.

The pavements in areas exceeded 500mm in depth and all materials were selectively sourced, won, and processed from onsite borrow pits, variable in nature, that were proved and tested along the main alignment.

Also constructed were rail embankments and turnouts, extensive stormwater infrastructure, turkey nests, over 150,000m² of various hard stands for crushing and ROM stockpiles and an underpass to the Stuart Highway.

Many challenges were overcome onsite including the selection and sourcing of suitable material for the cut and fill operations and pavement construction, limited water supply and quality, and construction of the haul road and maintaining access to both the Wirrida Siding and the operating mine.

The project was successfully completed within the time and budget constraints and was the third Stuart Highway underpass that Lucas TCS constructed for various clients within a 30km radius.

Tropicana Haul Road | AngloGold Ashanti | NE Kalgoorlie, WA | 2011-2012

Lucas TCS was awarded the first contract on the Tropicana Gold Project in Western Australia to construct 223km of heavy haul road to service the new Tropicana Gold mine site located 300km North East of Kalgoorlie.

Works included the clearing and grubbing, stripping and preparation of over 4,000,000m² of area, cut and fill of approximately 500,000m³ and pavement construction of nearly 1,000,000 tonnes.

The project also included the construction of turkeys nests, hardstands and the construction of a 66m long precast bridge over the Ponton Creek.

Lucas TCS also provided camp accommodation and all facilities for the contract onsite and prior to construction designed and built a 250mm diameter—24km buried bore field delivery pipeline to service the project with water.

The Project encompassed 2 accommodation camps and multiple work fronts to complete the project in the 12-month time frame, including mobilisation and establishment.

Works were completed under project budget and with a peak workforce of around 75 personnel, road production averaged 700m per day.

Prominent Hill Concentrate Haul Road | OZ Minerals | Near Coober Pedy, SA | 2007-2008

The Prominent Hill Mine is a major copper and gold mine located 650km north of Adelaide and 130km South East of Coober Pedy.

From 2006 to 2008 Lucas TCS undertook 7 major packages of work for OZ Minerals for the Prominent Hill mine site development works.

One major contract included the construction of an 84.5km roadway from the Site Access Road to the Wirrida siding which was located on the Adelaide to Darwin Railway Line.

The works included stripping an 18m wide corridor through varying terrain, some of which was heavily vegetated and cut and fill of up to 150,000m³ of site won material to construct the formation of the roadway.

Pavement material was site won from borrow pits adjacent to the roadway and selective winning and crushing of this material was undertaken to minimise costs and provide a fit for purpose haul road.

Key to the success of this project was the design input by Lucas TCS to minimise the cut and fill earthworks and pavement thickness, and the use of pavement trials and testing to prove the suitability of the existing borrow pit material for use as pavement materials.

The works were completed on time and on budget.

Mine Infrastructure

Projects

McArthur River Mine | McArthur River Mining/Glencore | McArthur, NT | 2015-2018

Since late 2015 Lucas TCS has assisted McArthur River Mining with complex civil projects.

In December 2015, Lucas TCS were consulted to develop an alternative method to dealing with problematic clay materials for the Basal compacted clay liner, and after a site visit proposed trialling a stabiliser unit to condition the compacted clay liner.

Working closely with McArthur River Mining, Lucas TCS were able to demonstrate the benefits of using a stabilising machine or the clay moisture, laying and compaction over the traditional rip, blade mix and compact methods which had proven to be inconsistent for previous projects.

Lucas TCS was awarded the next stage of the works including subgrade preparation and compacted clay liner which involved selective loading, hauling, moisture conditioning and compaction of materials in excess of 500,000m3.

Works also included construction of the 230,000m2 West PAF run-off dam (WPROD) within a very tight programme to ensure completion prior to the onset of the wet season.

Following the successful execution of the works, the Lucas TCS project team were awarded further works for the 2017 dry and wet seasons to continue NAF preparation, alluvial and batter works and final flood level clay liner construction.

Further contracts were awarded with clay liner works and the construction of the Eastern PAF Run-off dam (EPROD).

Prominent Hill TSF Uplift - Stage 4 | OZ Minerals | Near Coober Pedy, SA | 2017

In 2017, Lucas TCS returned to the Prominent Hill Mine Site for the TSF Uplift Stage 4 project for OZ Minerals.

The works were comprised of two parts, which covered the raising of the northern and southern TSF compacted clay walls along with a wearing course and filter zone and the works for the removal and replacement of the tails discharge lines.

Ten zones at approximately 550m in length were established with up and down ramps at each 550m interval. Clay was placed approx 6m wide and approx 375mm thick to achieve a 300mm compact layer once rolled.

Both the clay wall and filter zone were built 5m higher than the existing TSF wall with GPS enabled grader utilised to ensure the required levels.

The decant finger consisted mainly of a clay centre, sheeted on top with a wearing course and the decant finger walls armoured with course rock for added protection to avoid erosion and washouts.

Some project statistics include:

• 184,639m3 compacted clay to raise the TSF wall
• 131,560m3 filter zone material
• 131,113m3 clay and rock to raise the decant finger
• Approx 5,500m of tails line removed and reinstalled
• Approx 14,280 bolts used on installed tails line

TThe project was delivered on time and within budget whilst developing a collaborative working relationship with the client.

Solomon Spur Rail Embankment | FMG | Pilbara, WA | 

The Solomon Spur rail line involved the construction of a new embankment of approximately 142km and associated infrastructure to accommodate the new rail to the Solomon Mine located in the Pilbara region of Western Australia.

The works were separated amongst 4 contractors with Lucas TCS being awarded 28km of rail embankment for stages 5 & 6 of the Solomon Spur Rail project for the new FMG T155 expansion project

The work involved the sourcing, hauling, compacting and trimming of 500,000m3 of earth fill and subballast capping from local borrow pits along the alignment, and construction of over 6km of CSP culverts to withstand sheet flows and flooding regularly experienced in the region.

The works were undertaken as a 24-hour operation to meet the stringent project schedule and tight deadlines.

At peak over 120 personnel were engaged on the project across both shifts.

Lucas TCS mobilised and operated our own 170 man camp on site with overflow capacity from the main camp, as well as servicing the project FIFO operations with Lucas TCS company aircraft direct to site to avoid the long and hazardous transit from the mine back to Port Hedland.

Wonawinta TSF - Stage 1 | Cobar | Cobar, NSW | 2012

In 2012, as part of the mining contract, Lucas TCS completed Stage 1A of the Wonawinta Mine Site Tailings Storage Facility Construction.

Works included construction of the TSF which was approximately 700m x 700m in dimension with a footprint area of 49 hectares.

Stage 1A was constructed to contain a total of 900,000 tonnes of dry tailings and have the additional freeboard capacity to withstand a 1 in 100-year 72 hour flood event.

The embankment for Stage 1A was constructed up to 5m in height in controlled lifts and meeting stringent moisture and compaction specifications.

The works also included the construction of an access causeway to a central decant chamber and installation of a 550m length decant drainage pipe from the TSF central decant to process plant ponds

Prominent Hill TSF Uplift - Stage 2 | OZ Minerals | Near Coober Pedy, SA | 2011

In 2011, Lucas TCS returned to Prominent Hill for the Tailings Storage Facility uplift project for OZ Minerals.

This project was stage 2 south which included the lift of 5m around the full perimeter.

The project involved the construction of approximately 160,000m3 of clay liner, including ramps and the backfill of the wall and general plant hire.

Works were completed 2 months ahead of the original production schedule.

White Dam Process Ponds | Polymetals EXCO | Broken Hill, NSW | 2009-2010

In conjunction with the mining contract, Lucas TCS undertook the civil works for the construction of the HDPE lined leach pad.

The leach pad was for the extraction of pregnant solution from the heap leach operations at the White Dam Gold Mine.

The clay lined pad and HDPE liner was completed with a quick time frame to achieve the first gold production dates and exceeded 80,000m² in area.

White Dam HDPE Leach Pad | Polymetals EXCO | Broken Hill, NSW | 2009-2010

Lucas TCS in conjunction with the mining contract and the construction of the process ponds undertook the civil works for the construction of the HDPE lined Heap Leach Pad.

Construction consisted of two impermeable clay layers separated by a leak detection layer & 2.0mm HDPE Liner.

The Heap Leach operation was constructed during the life of the mine to a finished height of 22m. A sacrificial layer of material was placed over the liner prior to tipping ore to protect the integrity of the liner.

The ore on the leach pad was constructed in two lifts, the first being 10m and immediately followed by a 12m lift.

The material was mined selectively, and end tipped from an advancing face over the prepared pad.

The overall area of the Heap Leach operation exceeded 400,000m2.

The heap leach pad was planned to include the clay materials from the pit overburden removal, & had to progress at a rate that matched the mining of material, whilst being available for the stockpiling of ore which was contacted in the first few benches of the pit.

Due to the material balancing the leach pad was required quickly in the construction program of the mine to enable the targets of first gold production to be met.

In addition to the construction and mining, Lucas TCS also provided a Komatsu 465 60kL lime cart for the addition of lime to the stockpiles as they were constructed.

Jacinth Ambrosia Mine | Iluka Resources | Near Ceduna, SA | 2009-2010

The Jacinth Ambrosia Mine is one of the world’s largest mineral sands mines located 270km west of Ceduna in South Australia.

Lucas TCS were contracted to construct the following:

• Process water dams
• Environmental dams
• 5,500m³ of site batched concrete
• 4,000 hold down bolts
• 14km of underground services for the process facility including fire, process water and communications.

Despite the strict environmental conditions imposed by its location within a national park, the project was completed in just over 12 months with no Lost Time Injuries or environmental breaches and six months ahead of schedule.

Lucas TCS’ workforce entailed 180 personnel working across 7 contracts to complete all the civil works and trail mining and Lucas TCS were instrumental in assisting the project achieving multiple awards from industry bodies.

Lucas TCS proposed changes in the access road to reduce the cut/fill balance and adjust it to the local topography. This innovation cut three months from the project schedule and created a $4-5m saving for the client.

Jacinth Ambrosia Mine Process Water Dams | Iluka Resources | Near Ceduna, SA | 2009

As part of the Jacinth Ambrosia Mine Development Civil project, Lucas TCS undertook the construction of the process water dams, return water pond and concrete transfer weirs and spillways for the Jacinth Ambrosia Mine site, situated 300km west of Ceduna in South Australia.

The works involved the cut and fill of over 200,000m3 of material including the identification and removal of unsuitable subgrade material and the formation of batter walls in excess of 12m in height.

HDPE liner was installed to the pond including A64 cushioning geotextile and 1.5mm HDPE liner to the 300ML process water dam and 70ML Return Water Pond.

Despite the strict environmental conditions imposed by its location within a national park, the project was completed with no environmental breaches and Lucas TCS were instrumental in assisting the project achieving multiple awards from industry bodies.

Prominent Hill TSF |  OZ Minerals | Near Coober Pedy, SA | 2007-2008 

The Prominent Hill Mine is a major copper and gold mine located 650km north of Adelaide and 130km South East of Coober Pedy.

From 2006 to 2008 Lucas TCS undertook 7 major packages of work for OZ Minerals for the Prominent Hill mine site development works.

One major contract included for the construction of the starter embankment for the Tailings Storage Facility.

The Tailings dam was over 1.7km in diameter with a circumference of 5250m and required a clay liner to be installed to a thickness of 6m on the inside face of the dam.

Works included the excavation of a cut off trench through the oxidised shale material to a competent rock layer beneath, but due to the depth of this horizon, this proved difficult to achieve against the already placed waste rock forming the TSF formation.

Working with the designers, Lucas TCS work shopped a solution to use a Vermeer trenching machine to excavate a 900mm wide trench to the rock horizon to save the bulk excavation of over 3m of weathered rock.

The works also involved the moisture conditioning and compaction of over 500,000m³ of clay material, the installation of 4km of underfloor drainage and all associated infrastructure for return water systems.

The works were completed on time and under budget due to the reduction in rock excavation and at peak over 40 personnel were involved in the works.

Marine Construction

PROJECTS

West Beach Sea Wall Reconstruction | City of Charles Sturt | Adelaide, SA | 2018-2019

In 2018, Lucas TCS were contracted by City of Charles Sturt to reconstruct 280m of rock sea wall located at West Beach.

Due to storm events the stability of the rock wall had been negatively impacted, leading to wave overtopping and collapse of many sections of the wall.

The rock wall height was 6.5m in height with reinforced concrete ‘L’ walls to define the upper edge of the sea wall whilst retaining ground on the landward, coast park/car park side.

The scope of works included:

• Demolition of the existing sea wall and the sorting of rocks to maximise the reuse of rock from the existing seawall.
• Placement of all additional required rock including unloading, handling, stockpiling, placement finishing
• Reconstruction of the revetment seawall including the cast in situ retaining wall and crown wall and the precast concrete retaining wall elements.
• Construction of all required stormwater infrastucture, concrete footpaths, fencing etc.

Thevenard Marine Offloading Facility | Maritime Constructions | Ceduna, SA | 2018-2019

In 2018, Lucas TCS were contracted by Maritime Constructions for the civil works associated with the construction of the Thevenard Marine Offloading Facility, a purpose built facility for the loading and unloading of commercial fishing vessels.

Lucas TCS were contracted for three distinct activities which were undertaken in stages.

The first was the placement and compaction of core fill, placement of geotextile fabric and the placement of the primary and secondary rock armour.

Lucas TCS were also responsible for the establishment and maintenance of a haul road between the pit and the project site and the supply and installation of the stormwater system.

Each activity was run in sequence over a length of the breakwater based on forecasted weather and tide events to ensure that the potential for erosion was reduced.
