Abergeldie invests in NZ microtunnelling experts

Abergeldie and Mike Harker, whose father Graeme founded Harker Underground’s in 1988, have collaborated to purchase the business and its equipment from Hawkins, who has owned the company for six years.

Mr Harker said “I am delighted that the Harker family will once again own a share of the business my father founded. My brother Phillip will also continue to be a key member of staff.”

“I have known Mick Boyle and Abergeldie for around seven years and I have no doubt we will work well together and Abergeldie Harker will be very good for our employees and our clients and continue our father’s legacy.”

Abergeldie Harker will bring new capabilities to the New Zealand market, such as shaft sinking by blind boring, pipe relining, excavation by blasting, as well as capabilities in the water and rail sectors.

Abergeldie Executive Chairman Mick Boyle said “Harker has a strong reputation built over 30 years, good equipment and very capable people.

“Most importantly for me Harker has a culture similar to that of Abergeldie based on safety, innovation, hard-work, fairness and building better communities.

“The investment by Abergeldie in Harker will allow Abergeldie and Abergeldie Harker to share technical expertise, personnel and equipment.

The transaction is expected to be completed by the end of the month, with Abergeldie owning will 80 per cent and Mr Harker 20 per cent of the new company.

Harker National Manager Matt Mules has been appointed General Manager of Abergeldie Harker.

Catering for growth in Sydney’s North West

The NWGC package of works commenced in 2006 when the NSW Minister for Planning announced the first release of land in the area.

The land release is collectively known as the First Release Precincts and includes North Kellyville, Alex Avenue, Riverstone, Riverstone West, Colebee and Area 20.

Package 1 of the NWGC, which has now been completed, included the construction of a new drinking reservoir and approximately 23 km of drinking water, recycled water and wastewater pipelines.

In addition to this, new services were provided in the Riverstone and Alex Avenue Precincts including:

  • A 40 million litre drinking water reservoir and associated connection work on our land at Cudgegong Road in Rouse Hill
  • Drinking water pipelines to service the new precincts
  • A wastewater pipeline to service the Alex Avenue precinct.

Sydney Water has a number of water and wastewater infrastructure projects planned as part of the North West Growth Centre (NWGC) package of works, which is designed to cater for projected population growth and new housing developments.

Packages 2 and 3A of the NWGC project commenced in early 2013. Veolia’s work on the NWGC was part of Package 2 and included the installation of three wastewater lead-ins in Riverstone. Totalling 3.1 km, these leads in were:

  • Wastewater lead in 1 – 1.4 km, DN375 PP, DN375 GRP, DN375 and DN300 PVCU
  • Wastewater lead in 2 – 0.9 km, DN300 GRP and DN300 PVCU
  • Wastewater lead in 3 – 0.8 km, DN300 GRP and DN300 PVCU.

Veolia was awarded the contract on 19 October 2015, commenced works on 10 December 2015, and completed the project on 18 July 2016.

The lead ins were constructed using open cut trenching and microtunnelling, with Veolia awarding the microtunnelling subcontract to Pezzimenti Tunnelbore.

Microtunnelling was selected to complete the work as it was determined to be a more accurate and cost-effective method when compared to horizontal directional drilling (HDD) and thrust boring.

The contracted works also covered clearing project corridors; constructing the sewer lead-in main to be connected to the existing maintenance holes on the Chain of Ponds Carrier; constructing all inlets, maintenance holes, vent shafts and other structures associated with the sewer; and constructing the connection to the existing carriers.

Excavating the access shafts and identifying areas to store potential excavation spoil were some of the key challenges of project delivery.

Community consultation was another major consideration, with commercial properties and private houses located very close to the project works.

The project has now been finalised on time, with no major non-conformance. The key to the success of this project was the high level of project management, strong planning skills, and high-level focus on safety performance.

The next stage of the NWGC project includes Packages 3B, 3C, and 3D. Work on these packages commenced in mid-2016 and is expected to be completed by mid-2018.

Vineyard, Riverstone East, Riverstone West, North Kellyville, Box Hill, Box Hill Industrial, Alex Avenue, Schofields and Schofields West Precincts are all included in these packages of works.

Lendlease brings the nbn to Orange

The international property and infrastructure group has played an important part in the nbn rollout, which has seen the use of Trenchless Technology for everything from utility location to underground cable installation.

With rollout work already underway in Orange, Lendlease and nbn anticipate that at least 18,000 homes and business will be connected to the network by August 2016.

Kelly Stevens, nbn spokesperson, said “This is great news for locals who will soon be able to rival people in the city when it comes to speed and reliability.

“They join more than 1,600 homes and businesses in outlying areas that are already able to access the network through our fixed wireless technology.”

Ashley Mason, Managing Director of Lendlease’s Services business, said “Our work will help to connect 18,000 homes and business in Orange to the nbn as well as another 18,000 in the surrounding region, including Bathurst later in the year.

“We’re excited to be the construction partner for the nbn in the region.”

In addition to the NSW rollout, the nbn is making steady progress in Tasmania, with an addition 2,500 homes and business covered by the network in Rocherlea and Newnham.

Tasmanian Corporate Affairs Manager Russell Kelly said “More than 121,000 premises in Tasmania now have access [to the nbn] with thousands more being connected each month.

“It follows a successful year for the nbn in Tasmania in 2015 – the network footprint grew by around 80 per cent over the calendar year.”

Launceston has seen many of the benefits of the network as one of the leading cities for network connection.

Mr Kelly said “In urban Launceston all suburbs are now finished construction, under construction or in planning.

“All of urban Launceston is schedules to be under construction or finished by mid-2016.”

TERRATEC MTBMs head to Thailand

Italian-Thai Development Public Company, a main contractor on the MRTA Green Line (North) Project, will use the MTBMs for the pipe-jacking installation of power cable tunnels associated with the Sky Train System. The microtunnel boring machines (MTBMs) have been manufactured for the installation of concrete pipes with inside diameters ranging from 1,500 mm to 1,800 mm with a maximum length of 3,000 mm. Designed to operate in typical Bangkok soil, which ranges from regular clay to very stiff clay, the machines are expected to encounter several challenges including wooden piles and ancient housing infrastructure. To meet these challenges TERRATEC designed the MTBMs with an integrated Cone Crusher in the cutter head. The machines also feature a laser guidance system, a data recorder and remote access capabilities. While the machines themselves were designed at TERRATEC’s engineering centre in Australia, the production and assembly of the MTBMs was completed at the company’s manufacturing site in Thailand, using parts imported from Australia and Japan.

Celebrating Saint Barbara: patron saint of tunnelling

The early Christian saint and martyr, known as Great Martyr Barbara in the Eastern Orthodox Church, was born in the mid-third century close to present-day Lebanon. Saint Barbara was the daughter of Dioscorus, a rich pagan who guarded her carefully by keeping her locked away in a tower. When Dioscorus came to Barbara with a potential husband, she rejected him and told her father that she had become a Christian. Angered by her confession, Dioscorus attempted to kill Barbara. Legend says that she escaped his wrath by being miraculously transported to a mountain gorge. Despite her escape, Barbara was pursued by her father who then cruelly tortured her in order to force her to renounce her faith. When Barbara refused he condemned her to death by beheading. Dioscorus carried out the beheading himself. As punishment for this Dioscorus was struck by lightning and killed. It is this legendary association with lightning that gives Saint Barbara her contemporary connection to the tunnelling profession and other industries that use explosives, such as mining. Although tunnelling might not be as explosive as it once was, particularly with the rapid growth of the trenchless sector, tunnel boring machines are still giving female names in honour of Saint Barbara. It is also common for tunnelling projects to celebrate Saint Barbara ahead of tunnel construction, by placing and blessing a small statue of the stain close to the launch site.

Work completed on Port Macquarie sewage pipeline

The pipeline will transfer sewage from the northern side of the Hastings River to the existing sewage system on the southern side.

The installation of the pipeline marks a significant milestone for the project, and for North Shore residents.

Jeffrey Sharp, Port Macquarie-Hastings Council’s Infrastructure and Asset Management Director, said “There are more than 280 properties on the North Shore that will benefit from the new sewage network which delivers better environmental outcomes for the community.”

With work on the first pipeline complete, the next stage of the project will be to replace street mains and connect private properties into the new network, including installing pipes to connect street mains to new pressure units.

“The majority of these connections are being under bored, rather than installed in trenches, to minimise the impacts to residents and their yards,” Mr Sharp said.

Project works commenced in May 2015 and are scheduled for completion by July 2016.

The total project value of AU$9.5 million. This is being jointly funded by the Port Macquarie-Hastings Council and the NSW State Government.

Golden Gecko awarded to innovative microtunnel project

The Wheatstone microtunnel links a 225 km long offshore gas pipeline to the onshore processing facilities, protecting the coastal area adjacent to the Ashburton River Delta. Mines and Petroleum Minister Bill Marmion presented the Golden Gecko Award to Chevron Australia at an awards ceremony on Thursday 29 October. Department of Mines and Petroleum (DMP) Executive Director Environment Dr Phil Gorey said the project project stood out to the selection committee and was a very deserving recipient of the 2015 Golden Gecko Award. “The Wheatsone natural gas development is adjacent to the Ashburton River Delta, which supports important mangrove and estuarine habitats,” Dr Gorey said. “Chevron investigated five options for a shore crossing and chose the one with the lowest environmental impact, even though it was the most expensive choice. “Their commitment to environmental excellence was evident from the level of assessment and engagement undertaken during the project’s development. “Monitoring undertaken on the Ashburton River Delta demonstrated excellent environmental outcomes with no ground disturbance and an increase in the number of mature mangrove trees adjacent to the tunnel corridor. “Other excellent environmental initiatives included using biodegradable hydraulic oils, not using chemicals for the last 50 m of tunnelling, reusing all tunnel spoil, recycling almost all recyclable waste, and formally recognising individuals who improved environmental awareness of the project through an award program initiative. “This is the first time Chevron has successfully used microtunnel technology in the oil and gas industry and it is the longest pipe-jacked tunnel in the southern hemisphere.”

Hart on civil construction outlook

Mr Hart started his presentation by joking that Australian has changed its focus from mining to infrastructure; saying this was nowhere more evident than the department he worked in, which was formerly named ‘Mining & Infrastructure’, and now is titled ‘Infrastructure & Mining’. This global shift in focus was a key theme of his presentation, in which he said that while the construction industry may feel the crunch now in an interim change period, there is a strong forecast for growth in infrastructure in Australia by 2017. Australia’s economy is growing, but struggling to rise above the 2 per cent GDP per annum we are currently in. The fact we are still experiencing growth, Mr Hart says, is attributed to the resources sector – mining, oil, and gas – but it is not going to be a long term saviour for our economy and the federal and state government need to start shifting the focus of public investment. The bust of the mining industry Mr Hart predicts the ‘mining bust’ still has two to three years to run, saying “we have not hit rock bottom yet”. Because of the declining mining and minerals industries, which have primarily boomed in Queensland and Western Australia, it is not surprising the forecast for investment across the states of Australia show definite winners and losers over the next two to three years. Predictably, Queensland and Western Australia will be hit hardest for growth and investment, with New South Wales and Victoria in a much stronger position due to upcoming infrastructure projects in road and rail. Mr Hart gave advice to those involved providing infrastructure contracting to plan and prepare for what will be a tumultuous time for the industry over the next 3-5 years by looking state by state and by sector in planning future investments. He advised to assess the opportunities and risks involved, and to strike now and lock in low level costs on projects over a long period of time if the opportunities arise. For infrastructure providers, he recommended looking at the best time to deliver long term projects to avoid ‘busts and booms’ that give increasing cost risks along the way. “Booms come through and you get higher costs of delivering infrastructure,” he said. Looking globally “Globally, economic conditions are very volatile,” advises Mr Hart. “We have a slow moving global economy at the moment. First came the financial crisis, then the stimulus money followed after that. It’s improving gradually but not dramatically so.” For China growth is slowing. However, while its growth rate is slowing, the amount they are adding to their economy each year isn’t, due to the size China grows per annum. This seems positive in representing future economic opportunities for Australia, whose trade bolsters our economy. However, the problem for Australia is that the Chinese economy is shifting; it’s no longer being driven by infrastructure investment that demands the minerals and raw materials that Australia has been supplying. Investment in infrastructure According to Mr Hart, Australia has just passed its peak in oil and gas investment. The former $40 billion dollar investment in oil and gas is falling, and Australia needs new drivers for growth. Public investment, he says, is vital to this. Public investment in infrastructure has been falling since 2010. For the past two years, the country has also had declining investment in mining, in addition to the declining investment in infrastructure. “No wonder you’ve been feeling pain, two big drivers working against you,” he said – a sentiment that would reign true for many in the civil construction industry. However, Mr Hart states that public investment is picking up from here, and that NSW is going to surge – especially in road and rail, key industries where trenchless relocation of services are required. Things still look tough for the infrastructure sectors until this shift in focus happens. “Over the next few years we will feel the squeeze from the mining investment downturn,” said Mr Hart. “After this year we expect to see housing stabilising – most states reaching a balance in the housing market. Only Sydney will still be over supplied in housing. “Engineering construction will be picking up later this decade. Currently we’re in a downturn in engineering construction that’s being driven by the mining bust, and we’ve also reached a trough in publicly funded works. However, things should start picking up again.” Mr Hart said the major question on his mind was how to package the predicted investment in infrastructure so that it effectively sustains the construction industry, not just the bigger players who can bid for billion dollar investment work. How do we involve the whole industry? What industries will see investment? Water: The key area Mr Hart pegged overdue for water infrastructure investment was in regional areas, and said we should start to see funding come through for this over the next few years. The over-investment in desalination plants and dam infrastructure would see somewhat of a general downturn for water investment. Electricity: Australia still needs to invest a significant amount of infrastructure to meet its renewable energy target. This will result in building more wind farms and potentially a solar tank to meet this energy target. Telecoms: The National Broadband Network continues to drive civil construction work in this sector. Oil and gas: Mr Hart says the bust in this industry is due to last another few years yet, but advises the construction industry to not pin any hopes on a mining recovery. Ending his presentation, Mr Hart emphasised the need for far-thinking vision, giving the Sydney Harbour Bridge as the example par excellent. Even though it was built in 1930, when very few cars were on the road, they gave the bridge eight lanes. They foresaw the population’s the future needs. While the civil construction industry will feel the downturn of the mining and resources industry, as Australia turns its focus to investment in infrastructure,

Vermeer opens flagship Melbourne facility

A burst occurred on 18 January, in one of two pipes under the Fitzherbert Bridge, disrupting water supply and affecting pressure in some parts of the city. This follows a burst in the other pipe on 8 December 2010. The council said it is quite possible it would look at replacing the 25 year-old fibreglass pipe, instead of just carrying out repairs. Palmerston North City Council Water and Wastewater Services Manager Chris Pepper said “If the pipes are susceptible to regular failure, replacement could be a better option.” Mr Pepper said that if it is decided to replace the pipe “a trenchless solution would definitely be considered.”

Auckland sewer tunnel gets geotechnical

The Central Interceptor is a planned 13 km wastewater pipe from Western Springs to the Mangere Wastewater Treatment Plant.

The 4.5 m diameter pipe will lie between 22-110 m below the surface, with the Manukau Harbour crossing to occur at a depth of 30 m below the seabed.

The project’s resource consent application and environmental assessment, published in 2012, said construction of the tunnels would likely utilise a pressurised face tunnel boring machine – similar to the equipment used on Project Hobson and the Rosedale Outfall.

Link sewers would then be constructed using a combination of microtunnelling/pipejacking techniques, open trenching and reusing the main tunnel’s TBM.

Watercare Project Manager David Ward said the June geotechnical investigations, consisting of a series of boreholes along the proposed tunnel route, were required to dictate the specifications of the TBM and its operation.

“We need to better understand the ground conditions. We believe there’s a geological faultline in the harbour and it is important we identify its exact location,” said Mr Ward.

According to the Watercare project page, the Central Interceptor has an estimated cost of $NZ950 million and will duplicate ageing parts of the wastewater network, helping to both reduce overflows and cater for future population growth.

Advertising online is a great way to cost-effectively test if a particular market is a good fit for your product or service.

Business marketing: the value of advertising online

Remember when you first developed your company website? Just like email, your website has revolutionised the way you sell your company and its products and services to the world. Search engine optimisation can only take you so far and to reach highly engaged individuals searching for vital information, it’s important for your company to be advertising on the websites that matter in your industry. But what are the benefits of advertising online? Timely promotion and flexibility The immediacy of online advertising ensures that products can be introduced to the market very quickly. There is also design flexibility so web adverts can be eye catching and alternate between different banners. This also allows you to rapidly test different messages in short periods of time to see what is most effective. Tracking capabilities The best thing about online advertising is its ability to track the performance of your campaigns. Through using online advertising your company has the ability to track every single click and every single user to see if they end up becoming customers. It is worthwhile downloading Google Analytics – it’s free and will allow you to track the pathway visitors are taking to your site and their movements within your site. Are your online ads generating traffic? Which sites are referring visitors to your site? Google Analytics can help give you the answers. Cost effective Banner advertisements offer great value due to low production costs. If you have advertised before then you know that just one advertisement may not have the phones ringing hot, so think about what your aims are and perhaps look at booking a series of advertisements and combining this with strategically placed editorial content. Most websites have packages available and these should offer the best value and exposure over varied periods of time. High volume The sheer volume of visitors to industry websites means that by advertising you are highly visible to many new readers and potential leads. Most industry websites offer site visitors a free subscription to their e-newsletter which is often sent weekly or fortnightly to thousands of subscribers. By signing up, these e-newsletters subscribers have demonstrated a high-level of engagement, and so advertising in e-newsletters is highly coveted and tends to be a more exclusive and expensive online advertising option. Test the market Advertising online is a great way to cost-effectively test if a particular market is a good fit for your product or service. If you have a well-designed online advertisement and you are advertising on the right industry website then you should get some decent traffic – and those all-important leads. Entire industry coverage The best way to get entire industry coverage is to take out advertising in print, online, and have an event presence. If your company can only initially afford one or two of these promotional opportunities, the results will speak for themselves and you will have a clear case to argue for an increase in next year’s marketing budget. TIP: If you are taking out multiple advertisements then you should be rewarded with a discount, but also ask about securing some editorial coverage to maximise your impact. Highly targeted Visitors to industry websites are usually looking for information to help them do their job better, so they are highly engaged. Every person who views your advertisement is a prospective customer and you need to convey instantly that your product or service is what they need. Just online, all online? So, you’re a convert – you have decided your company needs to start advertising online. But what about your magazine advertising and exhibiting at prominent industry trade events? The good news is that online advertising is the perfect complement to your other marketing efforts. Online advertising is rarely enough on its own but by combining it with print and event participation in a strategically planned campaign, your company will receive maximum industry coverage and make a significant impact. Writing your advertisement Perhaps you have tried online advertising and you didn’t get the great results you expected. Be warned: the advertisement you run in your print campaign will not be suitable for online. If you use the same sort of advertisement you are unlikely to get the traffic you deserve. For best results you should make an offer and be instructive (find out, how to, click here). Through the use of ‘active words’ (for example: order, reduce, choose, use, apply), you can entice people to click your advertisement and learn more about your offer/product/company.

Sale of John Holland to Chinese construction group finalised

The conditions present in the share sale agreement between Leighton Holdings and CCCC International Holding (CCCI) were finalised 20 April 2015, allowing for the transfer of shares of John Holland and its subsidiaries.

In the Australian trenchless sector, John Holland is known for the Woolloongabba Sewer Upgrade Project in Brisbane, as well as the award-winning Melbourne Main Sewer Replacement Project in Melbourne.

CCCI is a wholly owned subsidiary of China Communications Construction Company Limited (CCCC), one of the largest listed companies in the international infrastructure and engineering sector, with listings on both the Hong Kong and Shanghai Stock Exchanges.

John Holland Group Managing Director Glenn Palin said the business was excited about the bright prospects for the future, with CCCC providing a platform with its balance sheet and international customer base.

Following the transfer of ownership, CCCC wants to double the size of John Holland within five years by building its established brand and taking advantage of opportunities in PPP investment, infrastructure, and selective investment in property and building development, said Mr Palin.

President of CCCI Lu Jianzhong said there were significant growth opportunities in the Australian market and John Holland was well positioned.

“We see John Holland as a strong independent competitor in the Australian market, with a clear vision for the future,” he said.

“We will bring certainty and a clear direction for staff, clients and the market.”

Microtunnelling for Melbourne’s West

Known as the Water for a Growing West Project, the pipeline will transfer water from St Albans Reservoir to Cowies Hill Reservoir, Tarneit. The project is worth up to $A30 million.

John Holland Group, the main contractor for the project, told Trenchless Australasia that the majority of the project will be constructed via the traditional open trench method.

“However, given the constraints of working in close proximity to – and under – live rail, the project team has also chosen to undertake microtunnelling methods,” said a company spokesperson.

“This technique was chosen as it minimises impacts and disruptions to rail services.”

The water main will service 40,000 homes and is designed to transfer up to 200 million litres of water a day – the equivalent of 80 Olympic-sized swimming pools.

According to Melbourne Water, the area is one of Australia’s top three fastest growing regions. While the existing network is performing well, an additional main is required to meet future demand.

Construction of the pipeline is due for completion in late-2015, with water services not affected during the construction period.

Ground broken for Sydney’s $A2.6 billion NorthConnex tunnels

The final contracts for the project were signed between private infrastructure operator Transurban, Federal Assistant Infrastructure Minister Jamie Briggs and New South Wales Roads Minister Duncan Gay.

In an announcement to the Australian Stock Exchange, Lend Lease said that its Engineering business had secured the $A2.6 billion contract for the design and construction of the NorthConnex project – including the integration of the widening of the M2 motorway.

Lend Lease is in a joint venture with France-based Bouygues Construction to deliver the project, with Transurban announcing the joint venture as the preferred tenderer in March 2014.

An overview of the NorthConnex project:

The project is a 9 km twin tunnel link from the southern end of the M1 Pacific Motorway to the Hills M2 Motorway. Key features of the tunnel design include:

    “¢ Twin 9 km motorway tunnels built with a three lane capacity (but initially marked for two lanes each way)

 

    “¢ A speed limit of 80 km/h

 

    “¢ A high clearance height of 5.3 m

 

    “¢ A northern interchange connecting with the M1 Pacific Motorway, the Pacific Highway and Pennant Hills Road

 

    “¢ A southern interchange connecting with the Hills M2 Motorway and Pennant Hills Road

Commenting on the contract, Minister Gay said the project has cleared the final stage of the unsolicited bid process and was the first major infrastructure in New South Wales to be approved under the State Government’s unsolicited proposal process.

Sewer microtunnelling project burrows beneath railway

The microtunnelling project in Victoria’s southeast involved burrowing more than 100 m beneath the major rural highway Princes Way and the VLine railway to make way for a new pipeline.

Edge Underground carried out the microtunelling project using Vermeer’s Axis vacuum microtunnelling method and HOBAS-supplied pipelines, with Fulton Hogan as the principal contractor.

Edge Underground Managing Director Stuart Harrison said the ground conditions and a risk of failure were the key reasons for Gippsland Water and project consultant GHD to opt for slurry and displacement microtunnelling.

“Many challenges had to be overcome in order to deliver a tight tolerance in vastly changing ground conditions,” said Mr Harrison.

“The use of a 350 mm pilot shot as a form of geotechnical sample proved to be a significant factor in delivering a successful project without requiring any additional shafts.”

The works, which follow more than two years of planning and design in consultation with VLine and VicTrack, were completed over two nights without any impact to train services.

Gippsland Water General Manager of Customer Service and Communications Paul Clark said the operation was the second of three critical sections of the final phase of the Warragul Central Trunk Sewer Replacement project.

“This investment allows for future development of the Warragul township along with fast-growing areas to the west and south of Warragul,” said Mr Clark.

“Previously un-sewered properties close to the Warragul CBD will also be serviced.”

Once operational, the new sewer main will have emergency storage capacity within the pipeline system, allowing Gippsland Water to decommission two existing pump stations currently located on the western edge of Warragul.

TBM1 Elizabeth just after she broke through at Norwest Station.

TBM breaks through for North West Rail Link

The 900 tonne tunnel boring machine (TBM) Elizabeth broke through into the station area just days after the fourth and final machine, Maria, began tunnelling on the project. New South Wales Premier Mike Baird said the TBM was launched at Bella Vista in September 2014, tunnelling 2.1 km to reach the Norwest site. By tunnelling to Norwest from the Bella Vista tunnelling site, TBM1 Elizabeth had:

    “¢ Excavated more than 206,000 tonnes of crushed rock, both sandstone and shale
    “¢ Installed more than 7,300 concrete segments to line the new rail tunnel
    “¢ Been home to 85 workers, including tunnellers, maintenance crews, geologists, surveyors and engineers, who combined have spent more than 25,000 hours underground
    “¢ Had 40 hardened steel cutters on her cutter head replaced.

New South Wales State Minister for Transport Gladys Berejiklian said the North West Rail Link was currently running ahead of schedule and $300 million under budget, with the project due to be open by the first half of 2019. The North West Rail Link includes eight new railway stations, 4,000 car parking spaces and a train every four minutes during peak hours. Over the coming weeks, Elizabeth will be moved through the Norwest Station area before setting off again towards Showground Station. The other three machines Florence, Isabelle and Maria, continue their digging work.

Future-proofing quake-prone assets

Not all of the damage done to Christchurch, New Zealand, by a string of bad earthquakes since 2010, is visible from the surface. A large portion of any city’s infrastructure lies underground, and has either been destroyed or damaged from the earthquakes. This damage includes most waste water systems in the city and the surrounding foothills.

In instances where sewer pipes completely failed, emergency measures during the natural disasters included temporary pumping, haulage or diversion until either the lines were restored or individual septic systems or collection tanks could be installed. Years after the earthquakes, there are still hundreds of miles of gravity-fed, clay-pipe sewer laterals requiring rehabilitation or replacement.

A trenchless solution

The Stronger Christchurch Infrastructure Rebuild Team (SCIRT) was created to oversee the reconstruction of Christchurch. SCIRT is a consortium of government agencies, known as “÷owner participants’ and of non-owner engineering, construction and maintenance providers.

One of the SCIRT’s fundamental tasks was to investigate and select techniques and materials that would not only repair infrastructure, but would also be able to stand the test of time and survive
future earthquakes.

In many places, trenching out the old lines was not an option. The durable, long-lasting materials SCIRT has chosen for replacing affected sewage laterals included polyvinylchloride (PVC) or polyethylene (PE) pipe.

These materials could be installed without the use of open-trenching through pipe bursting replacement technique.

Pipe bursting has proven to be not only one of the quickest trenchless installation techniques but one of the least intrusive to surrounding landscape and properties, as well as bearing a lower cost than other methods.

General Manager of Ditch Witch New Zealand John Grant said about 30 HammerHeadå¨ PortaBurstå¨ units were currently being used for pipe bursting projects in New Zealand.

PortaBurst units are 30-tonne pipe bursting systems used for replacing 50-150 mm lateral pipes.

As its name implies, the units are compact. Their modular design for easy disassembly, assembly and transport gives them even greater portability. Yet, the compact units have the power to easily fracture, press aside and pull 50-100 mm diameter PVC pipe through 45 m runs of existing vitrified clay pipe at rates of up to 3.7 m per min – without requiring excavation of the old pipe.

“In a lot of cases our contractors can’t use traditional excavating machinery to get to the pipe.

“They have to hand dig or use hydro-excavators, and they have to avoid disruptions to other services using the same trench,” Mr Grant said.

Mr Grant added that while initially his clients were just using the PortaBurst product for replacing pipe infrastructure underneath footpaths, driveways and around other utilities, they began selecting it for jobs that didn’t even require a trenchless method.

Pipe bursting became their first choice,” he said.

No longer a pipe dream

The feature of the pipe bursting system that struck Mr Grant first was how straightforward it was.

“Training does not take much time, it’s mostly done right on a job, learning how to dig the pits and shore them up properly, threading cable and doing the pulls,” he said.

For some of Ditch Witch’s customers who had never engaged with trenchless techniques during pipe rehabilitation works before, the uptake was easier than expected, Mr Grant said.

“At first the pull is done slower than in typical production, but customers catch on fast and are able to work on their own after that,” he said.

Mr Grant said he had one customer who reported he was astounded by what the product allowed him to do.

“Just doing crazy things, pulling around beams and retaining walls, he had heard that the PortaBurst could be used to make 45 degree bends, but he couldn’t believe it until he actually did it,” he said.

Typical runs on a Christchurch pipe burst are about 25 m, though under-road laterals may be 10-20 m long. They are almost all completed within a standard working shift.

Straight-forward bursting process

During a pipe replacement the PortaBurst contractor digs a pit on each end of a planned run down to the existing pipe. Much of the work is in pre-worked ground with silty sand matter, so pits are hydrovacced. The hydrovaccing makes a neater hole and is easier to restore.

SCIRT selects the replacement pipe options that contractors can choose from, some contractors have used threaded PVC, whilst others prefer to work with single lengths cut from reel stock or with fused lengths of straight pipe.

As the burst head progresses through the existing pipe, it fragments it, pushing the pieces aside whilst pulling the replacement in behind it. When it exits the other side, the contractor removes the head, documents his replacement work with CCTV, trims the pipe and reconnects it.

Ground conditions will return to normal around the pipe, with very little evidence of disruption.

THE LONG ROAD AHEAD

There is a tedious process residents go through to get approval for a sewer line replacement, insurance companies first have to approve the scope of repairs and the technique that will be used to fix them. Contractors are sometimes held up, waiting to start a job until the work is approved.

But there’s no end in sight for the work yet to be done. There may be anywhere from five to ten years of work to be undertaken. Not much work has been done in the foothills around Christchurch yet. There is ground seepage, and subsidence. And the earthquakes haven’t stopped.

Several years after the 7.1 magnitude earthquake in September 2010 and the deadly 6.3 quake in February 2011, the residents of Christchurch still live with consistent earthquakes yearly. More are inevitable due to New Zealand being located on the infamous “÷Ring of Fire’.

Nicknamed the “÷Shaky Isles’, New Zealand has consequently become advanced in post-earthquake rehabilitation techniques. Now, pipe bursting with the HammerHead PortaBurst system is one of them.
