Coleman Rail’s approach to operations is one that looks to manage and reduce the company’s environmental impact across all projects. Coleman Rail is dedicated to developing effective waste management solutions and initiatives that can reduce landfill and provide a better outcome for the environment and community.

During the tender process of the Preston Tram Workshops, the wooden floor blocks, located in Yarra Trams’ old industrial workshops, were identified as disposable landfill. However, through value engineering, the Coleman Rail team was able to develop a sustainable solution. Through collaborating with Earth Systems, a multidisciplinary environmental and social consulting firm, the team identified a potential purpose for the floor blocks that in turn reduced the project’s total landfill.

Earth Systems has developed a mobile biochar system called “CharMaker.” The product uses the pyrolysis technique to convert biomass to charcoal. Biochar is a form of charcoal that is regularly used for soil amendment. The product is seen to have huge potential for mitigating climate change and reducing the accumulation of greenhouse gases.

Biochar, when used as a soil additive; improves water and nutrient retention in soil, enhances the effectiveness of fertilisers, reduces soil acidity and increases soil carbon to improve the overall productivity of plant growth.

Through this initiative, Coleman Rail is not only reducing the needless contribution to Victoria’s already limited landfill, but also helping to increase the productivity of the Victoria’s farming community.

The company’s CEO Bede Noonan proudly encourages and supports the use of sustainable business practices, "We are committed to helping the environment to be sustainable into the future.

"Turning old wooden floor blocks from potential landfill into a valuable farming commodity is a fantastic example of this approach.”

Coleman Rail continues to embrace pioneering initiatives that lead to best practice models for the Australian infrastructure sector.

Coleman Rail congratulates Anthony Moore from the Preston Tram Workshops team for receiving the Safety Award for February 2015 as part of the project’s Safety Reward & Recognition Program.

The program was introduced at the $190m Preston Tram Workshops Redevelopment, to promote and advocate safety and well-being in the workplace. The aim is to facilitate discussion amongst employees and encourage workers to report potential incidents to the relevant Safety Officer. By recognising individual efforts, the company hopes to establish positive behaviour towards OH&S, which will in turn reduce the frequency of incidences in the workplace.

Project Director, Stephen Shaddock, applauded Anthony for his recent achievement, “Anthony identified a number of cracked welds that appeared on the basket of a mobile Elevated Work Platform.

“Thanks to his prompt reporting, we were able to quickly resolve what could have been a much larger issue in the long term.

“We encourage all staff to report anything they believe may pose a health and safety risk. Well done, Anthony,” said Stephen.

The Safety Reward & Recognition Program runs monthly at the Preston Tram Workshops Redevelopment Project. The next recipient will be announced at the end of March. 

Geotech’s specialist subcontracting capabilities were put to the test over the weekend of 13 February 2016, when we had three piling rigs and 30-odd employees working day & night out at Bentleigh Station on a rail occupation. The occupation ran from Thursday evening, 11 February, through Monday 15 February, as part of the Greater North Level Crossing Removal Project for John Holland. This follows similar weekend occupations at McKinnon Rd over the Australia Day weekend and two at North Rd in November.

New Royal Adelaide Hospital - Foundation Piles

Geotech was engaged by Hansen Yuncken / Leighton Contractors (HYLC JV) as a specialist civil subcontractor for the construction of foundation piles for the single largest infrastructure project undertaken in South Australia. Requiring CFA piles up to 1200mm diameter and 30m deep into some hard clays and cemented sands, it was on this project that Geotech commissioned their Enteco E25MD CFA piling rig: with 530 kNm torque, the rig is the most powerful of its type available in Australia. Throughout our involvement, Geotech continued to work with project Engineers Wallbridge & Gilbert and KBR to refine the pile design and provide further project savings. Our extensive scope included 2,000 no. deep CFA piles (up to 30m deep, 600/900/1200mm diam.), inclusive of dynamic load testing and analysis of over 100 No. test piles and break back (trimming) of all piles.

New Royal Adelaide Hospital - Permanent

Retaining Wall

Geotech was also engaged by HYLC for the construction of permanent retaining walls at the project. With the New Royal Adelaide Hospital (NRAH) building and free-standing retaining walls designed to perform under severe earthquake loading, the permanent ground anchors were a key concern for the project. Geotech used the patented Single Bore Multiple Anchor (SBMA) system to satisfy the performance based ground anchor design portion of the contract. The unitised nature of the SBMA system has the dual advantage of providing additional redundancy together with an increased load capacity when compared to traditional ground anchoring techniques in the sandy and clayey soil profile. This part of the scope saw us design and construct 450 no. permanent SBMA ground anchors; 400Lm of capping beam; 200No. soldier piles and spray 1,750m² of shotcrete infill panels.

Client: Crema Constructions

Crema Constructions engaged Geotech for the D&C of foundation piles and associated pile caps for a multi-story residential building. This saw Geotech designers undertake the D&C of approx. 180 bored and CFA cast in-situ foundation piles, consisting of up to 40m x 900mm diam. CFA piles and 45m x 1500mm diam. bored piles through Coode Island Silt and founding several meters into the underlying Melbourne Formation bedrock; and the construction of associated pile caps, ground beams, lift overruns and cores. Piling works were completed 5 days ahead of program.

M Docklands

Client: Hamilton Marino

The 2000m2 site is hemmed in by Lacrosse Stage 1 Apartments, Latrobe Street extension to north, Docklands Stadium to the south and the elevated Stadium Concourse to the west. Geotech’s specialist CFA piling plant was mobilised into site under the Stadium Concourse bridge structure with limited headroom. Our scope included the D&C of 104 no. 600-750mm dia. CFA foundation piles through Coode Island Silt founding in Melbourne Formation siltstone at 25-30m depth and subsequent dynamic pile load testing. The severely restricted access into the site during piling activities meant that Geotech was able to offer additional detailed excavation, pile trimming and pile cap/raft construction scope to Hamilton Marino Builders to ensure that the critical path works were progressed as a priority.

567 Collins Street

Client: Leighton Contractors

CFA foundation piles in challenging geotechnical conditions, on a site that required us to incorporate an existing single-storey brick retention system into the new 3 storey basement structure. With 26 storeys of structure above the Collins Street frontage it was not possible to rely on foundations sitting in the shallow finger of basalt rock underlying the site. Geotech’s D&C solution featured 900mm diam. CFA piles penetrating through the upper basalt flow and underlying weaker soils to found in the Melbourne Formation siltstone bedrock at depths ranging from 30-36m. Our scope included 100 no. passive soil nails to anchor the existing brick walls; 114 no. 600mm dia. soldier piles & anchors; D&C of 150 no. 900mm dia. CFA foundation piles up to 36m deep; and dynamic load testing and integrity testing of piles.

280 LT Lonsdale Street

Client: Brady Property Group

Brady Constructions engaged Geotech for the design and construct of a complete basement site retention and tunnel system, which required the unique solution of horizontal piles under Sutherland St to create a tunnel between the two basements. At a depth of 7 levels the project represented one of the deepest basements we have constructed and, having redesigned the piles to make the job more cost effective, we ended up installing 127 no. concrete reinforced bored soldier piles (ranging from 600-900mm dia.); 664 no. temporary anchors ranging from 250-400kN; and 2,200m² of shotcrete walls, 200-650mm thick.

Client: Pace Dg

5-level basement on a very limited footprint of only 700m². Challenges included a groundwater table at around 11m depth (retained height is typically 14-15m from St Kilda Rd level) and variable ground conditions (some ferruginous sandstone and granite). The initial design of the basement was the responsibility of Pace’s structural engineers. However, when those plans went before our designers, we were able to modify the approach in a commercially competitive way and Geotech was given responsibility for the design. Our final scope included the D&C of 73 no. 750mm dia. cast in situ soldier piles, 18-21m deep; construction of 120 lineal metres of capping beam; design & installation of temporary ground anchors – 250 no. with loads 200-400kN; and the D&C of 1,000m² of shotcrete panels.
