Tunnelling project hits milestones

The West Gate Tunnel Project will upgrade the West Gate Freeway and link it to the city and CityLink, providing road users with an alternative to the West Gate Bridge.

In preparation for the beginning of major tunnelling works in 2019, the North Yarra Main Sewer – a 100-year-old, 2.6 m diameter brick sewer routed below Whitehall Street in Footscray and Yarraville, carrying 20 per cent of Melbourne’s sewage – needed to be diverted.

A Herrenknecht microtunnel boring machine (MTBM) named ‘Mollie’ was launched in September and subsequently excavated 600 m in 35 days.

Moving at approximately 12 m/d, the MTBM created a new route as it installed glass reinforced plastic lining inside the tunnel to seal and strengthen the new infrastructure.

With breakthrough achieved, the MTBM has now been transported from the northern portal project site in Melbourne to Herrenknecht’s Thailand plant, where it will be sent off for use on another project.

At the northern portal, excavation of the launch shaft for the two tunnel boring machines (TBM) – ‘Bella’ and ‘Vida’ – ordered in January is almost 100 per cent complete.

The 15.6 m diameter TBMs will build a 6.8 km tunnel between the Maribyrnong River and the West Gate Freeway.

The gantry cranes are now in place to lift the heaviest parts of the machines into place, with one of the 450 t cutterheads already on site and ready to be lowered into the shaft.

On the western side of Williamstown Road, a pipejacking machine is now being used to relocate a 300 m section of a City West Water sewer main that crosses under the freeway.

Once this relocation project is completed, the TBMs will have the space required to breakthrough safely.

Contractor planning start of microtunnelling

The project to install a NZ$400 million (AU$378 million) water pipeline – Hunua 4 – from Manukau City to Auckland began in 2012 and is currently in service up to Epsom.

In October 2018, Watercare awarded McConnell Dowell the design and construction contract for the final section of the Hunua 4 Water Main Project, Section 11, valued at NZ$74 million (AU$70 million).

The scope of work comprises the construction of a 1.6 m diameter, 3.5 km pipeline from Market Road to the Khyber Pass Reservoirs in Auckland, primarily using microtunnelling.

A Herrenknecht microtunnel boring machine will install three of the five pipe sections under the road reserve.

According to McConnell Dowell, Section 11 of the pipeline will be the longest pipe jack completed in New Zealand.

The company said the project is underway and on schedule for microtunnelling to commence in the middle of this year.

Microtunnelling facilitates drainage culvert installation

In addition to completing the pipe jacking installation, the contractor also managed the design and construction of launch and receival shafts; safety, quality and environmental management; as well as monitoring.

Recently, D.J. Mac Cormick Contractors completed a microtunnelling project to install drainage culverts under the Pacific Motorway in Brisbane, Queensland.

The culvert installation is part of the Pacific Motorway Upgrade – M1/M3/Gateway Merge Project which is upgrading approximately 3.8 km of southbound lanes of the Pacific Motorway between the Gateway Motorway and Rochedale Road.

Installation

The project involved the installation of four culverts crossing beneath the motorway, ranging in length from 69 to 90m, with a total distance of almost 300 m. The pipelines were microtunnelled in close proximity to existing culverts, using jacking pipe with an outside diameter (OD) of 1,800 mm.

Launch and receival shafts were designed and constructed by D.J. Mac Cormick, while the required shoring was supplied by GSS Australia. The detailed temporary design of the shafts was supplied to the client as part of the scope of the project.

The MTBM pipe jacking the 1,800 OD pipe.

A closed face slurry shield microtunnel boring machine (MTBM) was used for the installation, with minimal overcut to the OD of the pipe. The four crossings under the motorway formed a critical component of the project. Ongoing settlement monitoring on all crossings was undertaken, with minimal settlement reported.

In addition, safety, quality and environmental management plans specific to the project were developed and implemented by D.J. Mac Cormick.

Equipped for trenchless installation

D.J. Mac Cormick has a fleet of Herrenknecht and Iseki MTBMs suitable for pipeline installation from 150 to 3,000 mm in diameter. The MTBMs are remotely controlled from the surface and are laser guided and steerable making them perfect for high accuracy grade requirements.

The company is also equipped with various cutting wheels suited for soft ground, mixed and rock geology. D.J. Mac Cormick has been executing microtunnelling projects since 1995 across Australia, as well as internationally in the Middle East.

NZ utility awards major construction contract

On Thursday 14 March, Watercare signed the contract with the GhellaAbergeldie Joint Venture (JV) from the group of contractors the utility had previously shortlisted to construct the tunnel and its associated infrastructure.

The 13 km wastewater pipeline is a vital infrastructure project and forms part of a strategy to protect and enhance the natural environment.

In addition to the Central Interceptor, Watercare has announced it will deliver other projects in the area including separating stormwater and wastewater tunnels.

https://www.youtube.com/watch?v=wvkLV50dVyU

The largest of these projects is the Grey Lynn wastewater tunnel, a 2 km extension of the Central Interceptor.

“We want everyone to be able to enjoy clean waterways, beaches and estuaries – that’s why we’re building the Central Interceptor,” said Watercare Chief Executive Raveen Jaduram.

“It will run underground from Western Springs to the Māngere Wastewater Treatment, collecting wastewater along the way via link sewers and drop shafts.”

“We are delighted to announce that the Grey Lynn wastewater tunnel has been included in our construction contract with Ghella Abergeldie JV,” said Mr Jaduram.

“This is an extremely good outcome for Aucklanders because it means a better result for the environment without any extra cost for customers.

“Together, the Central Interceptor and our western isthmus projects will reduce overflows in the area by at least 80 per cent.

“Because it is a key part of our region-wide wastewater strategy, it was important to find the best company in the world to construct it.

“So, after a vigorous tender process we chose Ghella Abergeldie JV with over 150 years’ experience working on major tunnelling and wastewater projects across the globe.”
 
Construction will start with site works in August and the whole project is expected to be completed by 2025.

Townsville pipe jacking nears completion

The microtunnel boring machine (MTBM) has nearly completed its drive to install jacking pipes on Townsville City Council’s Haughton Pipeline Duplication Project (HPDP).

The AU$215 million Queensland Government funded pipeline is considered an essential piece of infrastructure for Townsville’s water security.

It includes the installation of a 36 km, 1.8 m diameter pipeline connecting the Ross River Dam to the Burdekin Haughton Water Supply Scheme.

The pipeline will pump raw water into the Ross River Dam to top up water levels during periods of very low rainfall and is a key part of the town’s three-point water security solution, which includes the new pipeline, recycled water reuse scheme and a water smart package.

Townsville City council contracted the microtunnelling to D.J. Mac Cormick, which was supported by local supplier Humes.

“Long-term water security is still a crucial issue for Townsville even though the dam is full,” said Townsville Mayor Jenny Hill.

“The unprecedented monsoon shows exactly how unpredictable our weather can be.

“Our city needs to be prepared for the next time we enter into drought conditions and that’s why council is totally committed to building the pipeline.”

Townsville Water and Waste Committee Chair Russ Cook said the MTBM starting work was an important milestone.

“The floods have had an impact on the project’s timeline and we are working to complete the pipeline by March next year,” said Mr Cook.

“The pipeline is still council’s top infrastructure priority and we are working closely with all companies on the project to maximise the number of local jobs created.”

Member for Townsville Scott Stewart said it was good to see the project forging ahead where possible, despite severe weather.

“The Palaszczuk Government is investing AU$225 million to ensure water security for Townsville for years to come and it’s important that work continues and milestones such as this one continue to be realised,” he said.

The project was initially planned for completion in December 2019, with the delay pushing back its in-service date to March 2020.

WATCH: First TBM arrives in Melbourne

The machine, which will be used to build Melbourne’s AU$6.7 billion West Gate Tunnel, was shipped in parts to the Port of Melbourne, where Victoria’s Acting Premier James Merlino joined the Minister for Transport Infrastructure Melissa Horne were waiting to meet the cargo.

The rest of the pieces that will make up the TBM will be delivered over the coming weeks to the West Gate Tunnel’s northern portals in Footscray, before being assembled in the coming months.

The 90 m long, 15.6 m diameter Herrenknecht TBM is one of the biggest in the Southern Hemisphere weighing in at 4,000 t, and was manufactured in Nansha, China where its first test assembly was completed.

Specialised training for the project has now also started for more than 30 tunnel workers with a hyperbaric chamber installed on site so workers learn about operating in pressurised conditions.

Workers will work up to 35 metres below ground level and will need to spend up to two hours depressurising before returning to the surface.

Up to 20 people will work in the TBM at any one time.

The Victorian Government also announced a AU$124 million contract has been awarded to Liberty to supply 92,200 t of steel to be used across the corridor from Docklands to Laverton to reinforce the lining of the project’s twin tunnels, bridge segments, noise walls and retaining walls.

Last week, a microtunnel boring machine named Mollie made the first breakthrough as part of works to create a new diverted section of the 110-year-old North Yarra Main Sewer, which will make room for the West Gate Tunnel.

Tunnelling is expected to commence in mid-2019.

Spencer Street Sewer Upgrade reaches completion

The two-year City West Water project – completed ahead of schedule and within budget – has increased the capacity of the 122-year-old sewer to 25 times the capacity of the existing one.

A CCTV camera records the inside of the new sewer pipe.

In order to install the infrastructure, project delivery partner Quinn Civil and its sub-contractor Bothar Boring used a 9 m long, 1.5 m diameter microtunnel boring machine to install more than 700 m of new sewer main 11 m underground in Melbourne’s CBD.

Crews worked weekends and around the clock for over a year to complete the construction of the sewer, with minimal disruption to commuters.

Its completion has been commemorated with a plaque laid underground in the sewer.

The upgraded sewer is now connected and working, ensuring safe and reliable service to residents and workers at a time of unprecedented and rapid population growth along Spencer Street.

The sewer installation shaft.

This constitutes a milestone for the utility’s 10-year capital improvements plan for Melbourne to meet future demands and population expansion for the next 35 years.

“Our thanks to everyone, on and offsite,” said City West Water General Manager Infrastructure and Delivery Maree Lang.

“Especially to the local community and businesses, visitors to the city and the countless commuters who showed great patience and tolerance while works have been underway.

“It was, without doubt, a massive team effort.”

McConnell Dowell sets Direct Pipe world record

The MTBM, located at Watercare’s Army Bay Wastewater Treatment Plant in Whangaparaoa, New Zealand, completed what is currently the longest ever stretch of pipe laid by the Direct Pipe® tunnelling methodology.

According to the contractor, McConnell Dowell, the installation is a new world record.

The MTBM is being used to replace an old 2.8 km outfall pipeline.

On Friday 13 July, the NZ$6.2 million (AU$5.8 million) Herrenknecht MTBM surpassed the previous record of 1,495 m set in Texas, US last year.

Direct Pipe is a Herrenknecht trademarked MTBM that combines the benefits of microtunnelling and horizontal directional drilling into one machine, allowing the borehole to be excavated as a prefabricated pipeline is installed in one long drive.

The Direct Pipe system has been designed to achieve drive speeds of up to 30 m a day and is generally used to install pipelines under rivers and other large bodies of water in Europe.

“This is the first time the Direct Pipe system has been used in New Zealand,” said McConnell Dowell Project Manager Chris Powell.

“As a consequence we weren’t constrained by traditional applications and were able to use the Direct Pipe system it in ways not explored before.

“We set some pretty high expectations, we learnt much and achieved a real global step-change in how this new tunnelling technology can be used.”

Herrenknecht Asia Pipeline Expert and Area Sales Manager Ben Hayes congratulated McConnell Dowell on using the method to achieve a world record.

“The hands-on site team have been particularly impressive in their ability to adapt and overcome hurdles encountered – along with the support of Herrenknecht site personnel with their considerable Trenchless Technology expertise – to ensure an efficient and safe execution with a technology that was essentially new to them,” said Mr Hayes.

Construction upgrades to the treatment plant began in August 2017 and is expected to be completed in early 2019.

MTBM completes major works under Melbourne

The 9 m long, 1.5 m diameter MTBM has been installing more than 700 m of new sewer main under Melbourne’s CBD between Lonsdale Street to Flinders Lane as part of City West Water’s Spencer Street Sewer Upgrade.

The new sewer will connect with an existing pipeline to support the population growth in city over the next 35 years.

Quinn Civil is the Principal Contractor of the project, with microtunnelling operations subcontracted to Bothar Boring.

Update

On Friday 21 December 2018, City West Water announced that the Spencer Street Sewer Upgrade was complete, finished ahead of schedule, safely and within budget.

The upgraded sewer has been connected to service residents and commuters who live and work along Spencer Street, increasing the existing capacity of the 122-year-old sewer by approximately 25 times.

Project update: Forrestfield-Airport Link

Having safely installed more than 18,000 segments and completed 33 per cent of the route, TBM Grace has been fitted with new cutterhead teeth, with Sandy to receive the same treatment in the coming weeks.

The machines are now tunnelling between Airport Central and Redcliffe Station, so tunnel one has been closed between the Airport and Forrestfield for the construction of two new cross passages to start.

Microtunnelling works

At the 400 m long dive structure in Bayswater – forming the entry and exit point of the tunnels – more than 30,000 t material has been excavated so far.

The microtunnelling to install a main drain has also been completed, and a section of road along Whatley Crescent has been reopened.

Emergency egress shafts (EES)

The three emergency egress shafts along the alignment of the tunnel are now well underway, with the EES near Abernathy Road now poured and set to begin staircase, lift shaft and ancillary building construction.

Bulimba Creek hits milestones

The utility’s microtunnel boring machine (MTBM), Sewey, has completed its journey two years after it began work on the AU$55 million Bulimba Creek Stage 2 Sewer Upgrade which will carry wastewater to the Gibson Island Sewage Treatment Plant.

On 12 November, the MTBM made the breakthrough into Settlers Street Park at Carindale, marking the end of tunnelling for the Bulimba CreekSewer Upgrade.

Following this, a 22 m sewer pipe supplied by RPC made of glass reinforced plastic was successfully lifted and lowered into a 25 m deep shaft in Carindale for a maintenance hole on the sewer line.

Queensland Urban Utilities Project Manager Will Campbell said reaching breakthrough was a significant milestone for the project.

“After months of chewing her way through hard rock, Sewey emerged without the colourful design created by Easts Mt Gravatt Junior Rugby League Club member Caitlin Gamble,” he said.

“Most importantly though, she completed her mission.

“The new trunk sewer from Carindale to Mansfield will meet the needs of future growth in southeast Brisbane until 2050 and cater for an additional 271,000 people.”

During the project, 4.25 km of new sewer main was installed, with the majority using modern trenchless technology.

“As it’s a gravity trunk sewer, we’ve been working at depths of up to 50 m below ground, so using modern technology was paramount to reduce the impact on the wider community and environment,” said Mr Campbell.

“We thank residents for their patience while we’ve constructed this essential infrastructure, which enhances the liveability of our communities.”

Weather permitting, final works are expected to be finished by March 2019.
