DJ Mac Cormick project up for award
To complete the works at Pier Street and Milligan Street in Perth’s CBD, DJ Mac Cormick used a Herrenknecht AVN 600 closed faced laser guided steerable tunnelling machine to install Humes S series stainless steel band concrete jacking pipes.
The launch and receival shafts were constructed at depths of 4-5.5 m below ground level and with a combination of wellpoint and open pumping required at all shaft locations owed to the high groundwater table.
DJ Mac Cormick says the two crossings required detailed analysis and contingencies in place given the rail crossings were more complex due to the numerous lines required to be tunnelled under.
Detailed planning took eight months prior to the project, including detailed project pre-start tunnelling plans drawn up for each crossing to note location stops at every point on a daily basis.
DJ Mac Cormick said all crossings were successfully completed within the allowed shutdown periods of 10pm and 3.30am
The contractor has now successfully undertaken more than 100 rail crossings Australia wide, including 8 in Perth, 5 in Brisbane, 2 in Sydney, 1 in Melbourne and 1 in Townsville in the past 2 years.

Local servicing at its KOR
KOR’s new facility is located in Cockburn Central in the heart of Perth’s industrial zone and is a convenient 20 minute drive from Perth CBD, where it will support the industry’s growth in a region where vacuum and hydro excavation technology has thrived in recent years.
KOR says supporting WA’s growth with the equipment the industry needs is pivotal to the success of the state. Partnering with high quality product suppliers from around the world, KOR has the latest range of parts and accessories from Cobra, Southland Tools, Uraca, Duebre and an exclusive supply of Cappellotto equipment all in stock.
With Perth being the world’s most isolated capital city, KOR Business Manager for WA, South Australia and the Northern Territory Peter Jones – who lives locally in WA and is also the AUSJET ADVCA Chair – says Melbourne and Sydney are much further away than many people realise.
“Because of the significant distance between Perth and the eastern seaboard, it is important that we provide our customers the level of service and availability of spare parts they need locally in WA to confidently operate Cappellotto equipment,” says Mr Jones.
Further to its growth in WA, KOR has also opened a new facility in Preston, in Western Sydney’s industrial belt, to support Australia’s largest city with a spare parts range, unit availability and onsite industry professionals to support the product in the field.
KOR says this strategy supports the expansion of Australian cities and the large-scale infrastructure projects that continue to encourage economic growth.
“Projects including the Paramatta light rail, Greater Western Sydney Airport, a new runway at Melbourne airport, freeway upgrades and expansions across our cities and level crossing removal projects are all examples of projects where Cappellotto units operate,” said the company.
With unit parts and accessories now available in WA, Victoria, NSW and Queensland, KOR’s national footprint continues to grow, giving national fleets flexibility and local businesses access to a world leading industry equipment brand, Cappellotto.
KOR says customers trust the company because of its investment in the product, its Australia-wide operations and its continued product innovations that encourage a safer, environmentally friendly and more productive future.

VSA strides ahead with Vermeer
As an innovative trenchless technology contractor, Versatile Services Australia endeavours to use industry-leading tools and equipment – which is why the company works with industry pioneer Vermeer.
GM the go-to in WA
With 40 years of experience in the industry, the company has established itself as one of Western Australia’s most knowledgeable underground infrastructure companies.
GM Microtunnelling is part of WA’s history in the trenchless industry, with General Manager Gary Miller’s father Jim responsible for purchasing the first horizontal boring machine in the state. Gary and Jim recognised the increasing demand for this brand of underground construction and quickly established a name for themselves by winning contracts for various vital water and gas works.
The company adapted and progressed as the technology continued to improve through the decades and, although Jim eventually retired, GM continues as a family business today with Gary’s son and grandson both a part of the team.
Comprehensive knowledge
As both a primary or subcontractor, GM has installed pipelines beneath buildings, highways, railroads, runaways, rivers and environmentally sensitive areas. The company is capable of tunnelling through hard rock up to 660 m OD as well as cobbles, boulders, gravel, clay, sand and silts up to 800 mm OD, with its trenchless methods particularly suited to gravity sewer, water and drainage pipelines.
GM often works together with project engineers to provide planning and technical advice on a project and is able to set itself ahead of the pack thanks to its extensive knowledge of ground conditions throughout WA. Along with its local knowledge, the company has expert proficiency in the operation of a large variety of tunnelling machines including the Grundomat range and Essig air tools, along with auger, ramming, pipe bursting, pilot and slurry microtunnel boring machines (MTBMs).
With four complete systems in its fleet, GM can currently tunnel from 150 to 800 mm pipe to line and grade using polyvinyl chloride, concrete, vitrified clay, glass reinforced plastic and steel pipes. The company has its fingerprints over a large range of significant infrastructure projects in WA and is continuing to stay busy while the trenchless method of construction gains a greater standing as the approach of choice for many asset owners.
Some of GM’s works include the completed installation of a gravity sewer in Wungong Reach with a DN 650 Hobas pipe after a 1,200 m bore at a depth of 6.5 m. At Heron Park in Harrisdale, GM completed a 450 m bore at a depth of 9 m for a gravity sewer using DN 600 steel casing, while the company was able to bore 300 m at a depth of 5.5 m for a gravity sewer in Parkland Heights, Baldivis.
GM is a fully accredited contractor operating in line with integrated management system standards ISO9001 2015, ISO14001:2015, ISO45001:2018 and is an approved Tier 3 Water Corporation supplier.
Though it has already acquired a vast wealth of industry knowledge and experience, the company intends to lead the trenchless technology industry through its consistent embrace of new methods and innovative ideas. GM is regularly participating in and encouraging the training of new personnel in the industry and places the upmost importance on its quality of service.

No catch-22 with MCS on board
McRobert Contracting Services (MCS) is an Australian-owned and operated industry leader in the refurbishment of underground assets and polyvinyl chloride (PVC) pipeline technology. Operating out of Perth, WA, the company has been in operation for more than 30 years and has evolved into a business whose specialised services are sought out by both public and private sectors around the country.
MCS has worked on hundreds of projects across its lifetime and has developed a unique patented method for the structural relining of access chambers suffering from sulphide corrosion. The company’s strong relationships with a range of water operators across Australia are helping it achieve its vision of being the first choice for rehabilitation services, backed by its consistent ability to offer industry leading services and products to existing and future customers.
Doing what MCS does best
On 12 June 2020, MCS – in association with the Water Corporation – completed a contract to rehabilitate 22 access chambers that were deemed to be of an extremely poor condition in Cottesloe, WA. Before the actual refurbishments began, MCS employed its latest 3D scanning technology to assess the structural integrity of each access chamber and cross reference detailed measurements to determine the assets’ conditions.
These reports provided critical information for the method of rehabilitation MCS would use. The chambers were predicted to be challenging due to their high flows, silt/debris content, already fragile overall structure, advanced age and proximity to Cottesloe’s popular beach front.
After careful deliberation, it was decided to carefully jet-wash and e-duct approximately 5 m either side of each chamber to reduce the otherwise high cost to clean and e-duct kilometres of pipeline. This jet-washing/e-ducting process was also able to assist in reducing the amount of silt and debris in each chamber.
Additionally, the jet-washing and e-ducting significantly lowered the flows along with the isolations provided by Water Corporation to a workable level. This decision, as well as having the capacity to work with the prefabricated channels, allowed MCS to specifically adapt and design a solution to allow for the successful and safe installation of channel and benching with the remaining refurbishment works to be completed prior to the allocated project schedule.
The specific scope of works for this project comprised the design and development of structural rehabilitation for the current asset structure using approved remedial methods, including surface preparation for rehabilitation, channel and bench fabrications and the installation of the PVC lining system.
This also included the supply and installation of all required lining materials, supply and installation of PVC lined lids, reinstatement of property to previous conditions, spark testing completed to Water Corporation standards and the provision of quality assurance documentation.
Track record of success
When faced with a relining project, MCS uses a minimum 10 mm rigid PVC sheeting, with the chamber walls prefabricated into sleeves that can be lowered into place directly onto the asset. MCS also prefabricates the PVC channel and benching components, which are then plastic welded into place in the chamber.
After installation, the preformed sleeves, channels and benching are secured to the original asset using a minimum 40 mm of high strength grout. MCS relines the access chambers from top to bottom including pipe connections, channel and benching resulting in a 100 per cent gas tight structural PVC lining. This ensures complete protection of the asset from concrete deterioration.
Although MCS guarantees a period of 50 years for the plastic lining of utilities access chambers and sewer pumps, PVC linings should last significantly more than 100 years, provided no physical damage or prolonged exposure to UV occurs.
Continued excellence
MCS has developed its relining methodologies to ensure it maintains a safe working environment while completing tasks in the most efficient manner possible. The company aims to spend as little time in the chamber as possible, equating to less time spent onsite and minimising extra costs that can accompany issues like traffic management.
Although based in WA, MCS has, and continues to, offer and complete its services around Australia. Along with access chamber refurbishments, these services include sewer pump station refurbishments, plastic fabrication, onsite fabrication, 3D laser scans, pressure jetting and CCTV inspections.
