The company has maintained a strong presence in PNG since 2017, where is services local oil, gas and mining projects. With headquarters in Port Moresby, on the south east of the island, it is able to support the ongoing development of PNG,
The location of the office allows Nacap to recruit from the local community and support their ongoing development.
The company is part of Quanta Services, Nacap is a specialist engineering, procurement and construction (EPC) contractor. It also offers specialist design services, and works on high voltage infrastructure.
With a strong presence in the Highlands of PNG, Nacap has previously completed works on a project in Kutubu, a remote location in the area. The project required complex condensate reinjection works.
The range of services supplied by the company include complex pipeline crossings such as swamp and shore zone pipelines, infield pipelines and gathering, civil construction and HDD projects.
The TBM has begun to tunnel its way from Karanga a Hape (Karangahape) Station towards its final destination at Te Wai Horotiu Station (Aotea).
The previous breakthrough, at Karangahape was a huge achievement for the teams of workers supporting the massive infrastructure project.
In order to relaunch the TBM, workers had to transport it across to the next subtunnel and use a thrust frame to push it against the tunnel so it could start boring again.
The CRL project is still the largest infrastructure project in New Zealand. It has been undertaken while complying with a list of more than 500 conditions from Auckland City Council, as well as authorities obtained from Heritage New Zealand.
The next breakthrough will complete the tunnelling portion of the 3.45 twin-tunnels project. So far the TBM has bored 1130 metres of the second tunnel, installed 539 concrete rings, and removed over 75, 000 tonnes of earth.
The project costs $4.4 billion, and will double the number of people within 30 minutes of central Auckland – the largest employment hub in the country. When fully operational, it is believed that 54, 000 passengers per hour will utilise CRL stations during peak periods – around double its current capacity.
The tunnels connect two existing stations – Waitematā (Britomart) and Maungawhau (New Eden) – as well as containing the two new underground stations – Aotea and Karangahape.
Watercare’s renewal project aims to proactively replace more than 12,000 metres of freshwater pipes by the end of 2022. The goal is to reduce leaks and prevent water outages in the area, boosting the networks’ overall resilience for the future.
In Kelston, Watercare have replaced about 2.3 km of old water pipe. Most of the pipe being replaced is up to about 50 years old. In New Lynn the situation is similar, with a further 3.5 km of pipe being replaced.
The upgrade will also reduce operating costs, as future maintenance needs will be lessened with a new, robust system in place.
The new pipes have a projected lifeline of around 100 years, and are being installed with the help of horizontal directional drilling (HDD) technologies. Project Manager Mark Chijindu says that the HDD method allows the renewal to be undertaken much faster, and to a higher quality than otherwise, while maintaining the safety of workers on the project.
“Horizontal directional drilling is also better for the environment than open trenching as it lessens the impact on the surrounding residential assets and reduces fractures and soil disturbance,” said Chijindu.
The works commenced in February of this year, with New Lynn already completed, and the works in Kelston projected to be finished by 16 September.
The first event of its kind in Australia, AUSJET22 will bring together industry experts from around the country.
EXHIBITION
The event’s trade show will feature water jetting, drain, vacuum and hydro excavation industry leaders. The exhibitors will be spread across an indoor and outdoor footprint, presenting the newest technologies and quality supplies for their industries.
Demonstrations will be taking place throughout the event, with the schedule including interactive installations across a number of Live Demonstration Arenas, giving visitors the opportunity to get and see hands-on with the newest advances and state-of-the-art technologies.
EDUCATION & NETWORKING
Complementing the exhibition will be a two day conference program, covering industry topics and new technologies and a Key Note presentation from Steven Bradbury, Australia’s first winter gold Olympian. The program will include free floor talks presented to the exhibition-only visitor base.
The ‘Sip + Connect’ cocktail function will be held on the show floor on the afternoon of the 12 October, bringing visitors together in an opportunity to meet old-friends and find new ones.
AUSJET22 is open to anyone involved in high pressure water, drain cleaning, hydro excavation and vacuum industries, including users of these services as provided by industry contractors.
With a mission to develop a safe work environment through standards, training and advocacy, AUSJET22 is set to be an important event for the whole industry.
The company’s Southern California design and manufacturing plant is ground zero for the HDD tools that changed the way an entire industry drills.
The way Melfred Borzall does business sets them apart from the competition.
Not only has the company been the catalyst of the HDD industry movement for three-quarters of the past century, it has also been a legacy of three family generations.
When Fred Melsheimer left his position in the oil fields to start his own company it would be handed down from father to son.
Today that same family runs the company and are thriving with modern innovations and engineering to meet the needs of today’s driller.

A subsea gas pipeline was needed for Woodside Energy two transport liquified petroleum gas and condensate from two gas fields: Geographe (55 kms south of Port Campbell), and Thylacine (70 kms).
The transfer of the gas took place of a 20-inch diameter pipeline that will transport the resource to an onshore processing plant.
The transition from subsea to onshore pipeline was a key challenge in the transportation of the gas, as the area is well known for its high-energy wave conditions that could potentially damage any above-ground pipe at the coast.
Another challenge was that most of the coastline suitable for the work is classified as either National Park or Coastal Reserve, meaning environmental impact needs to be miniscule. The area was, and is, a major tourist destination, which further required that it be maintained in its current state.
The pipeline construction concept, delivered by Atteris, originally considered traditional open cut and cover methods. Microtunnelling options were also assessed, but deemed unfeasible when compared with larger-scale horizontal directional drilling (HDD).
HDD methods saw the project delivered under budget and within the recommended schedule. The study found that there was no detrimental effect on the local environment, and no lasting negative impact on communities in the area.
As oil and gas operators explore increasingly challenging areas in the search for more resources, these challenges are transferred in turn to pipeline engineers to overcome.
The Otway Gas Project formed a benchmark for trenchless solutions as a method for overcoming difficulty.
The project is being led by Melbourne-based civil engineering company Adept Civil Group for clients Winslow, and the multinational company Fraser Property, based in Singapore.
The work so far has involved a number of unique challenges, including the protection and maintenance of a detailed rock wall at the work site.
Construction centres around the building of a 1200 mm drainage outfall pipe, using trenchless construction technologies in order to minimise the impact on the local area.
Adept has extensive experience in the area, having worked on a number of larger projects in the past. Recently the company was contracted to facilitate the relocation of sewer pipes beneath Melbourne’s CBD ahead of the city’s massive West Gate Tunnel Project. The relocation required boring 30 m, installing jacking pipe, and building manholes. This had to be completed before the Tunnel Boring Machines (TBM) involved in the project could begin.
Winslow’s involvement in the project occurs alongside a broad range of projects across the country, including development and construction of residential projects, as well as roads and land remediation.
The West Harbour Tunnel will be the third harbour crossing project, alongside the Sydney Harbour Bridge and the original harbour tunnel.
The new tunnel will join the WestConnex at Rozelle with the Warringah Freeway at North Sydney. The project will include 6.5 km tunnels beneath Sydney harbour.
This first step in construction begins with excavation to pave the way for 1.7 kms of mainline tunnels connecting Rozelle and Birchgrove.
The project is aimed at easing pressure of existing arterial roads and corridors, including the Harbour Bridge and the Anzac Bridge. The tunnels will include three lanes of traffic each way, and has the potential to shave 15 minutes off commuter times between North Sydney and the Sydney Kingsford Smith Airport.
The second stage of the project involves the boring of a northern tunnel from Birchgrove to North Sydney through Sydney Harbour. The contract for the second stage has not yet been set. It is expected to be awarded later this year.
The West Harbour Tunnel Project is a major part of Sydney’s $110 billion infrastructure works, and takes place alongside the Rozelle Interchange works.
This first stage of the project, as well as construction on the interchange, is being undertaken by the John Holland CPB Joint Venture, allowing a streamline process using existing skills, equipment and resources to minimise disruption to the community.
Underneath every major city across the globe are networks upon networks of underground tunnels – many are used daily by commuters on trains or light-rail or even travelling by road.
The 3.45 km twin-tunnel rail link is being built to better connect Auckland’s rail network. It is expected to at least double the city’s rail capacity.
The most recent milestone for the CRL project is the tunnel boring machine (TBM) Dame Whina Cooper breaking through at Karanga a Hape Station on 15 July, slightly ahead of schedule.
During the works required for the CRL project, workers and partners are complying with more than 500 conditions from Auckland Council and must also comply with archaeological authorities obtained from Heritage New Zealand.
Management plans are in place to ensure compliance, and the project is being constantly monitored so that any breaches can be rectified quickly. Key to reducing the social and environmental impact of the project are the monitoring of noise and vibration, discharges, and disruption of traffic, parking and businesses. Groundwater levels are monitored in real time, 24/7.
MP for Northcote Shanan Halbert, who was present for the tour of the project, said that the completed project will ease congestion, cut commuting times and add significant peak hour capacity.
InJuly 2021, the historic announcement was made that Brisbane would host the 2032 Olympics after a vote by International Olympic Committee. The announcement triggered a series of development and infrastructure projects to lay the groundwork for the world stage.
The TBM, named Dame Whina Cooper, has finished the process of breaking through at Mercury Lane.
Boring for the final tunnel will head north, with the TBM heading towards Mayoral Drive and Te Wai Horotiu Station (Aotea).
CRL’s Link Alliance are preparing the final station for the TBM’s breakthrough in midtown.
Preparations include building a landing pad for the safe retrieval and removal of the TBM at the end of its journey.
Reinforcements are being set for the eventual platform and tracks beneath Mayoral Drive, which will be laid along the eastern tunnel that was completed last year.
Once the boring is completed, the tunnels will be fitted with:
16 km of rails
816 km of signal cables
247 km of low voltage cables
74 km of cable containment
86 km of traction cables
The TBM is being moved on rails through the tunnel cavern at Karanga a Hape Station. For some portions of this trip, there is as little as 1 cm of clearance for the machine.
Overall, the CRL is a 3.45 km twin tunnel project at a depth of 42 km beneath the city.
While the TBM only broke through at Mt Eden earlier this month, The CRL project is following a strict turnaround, aiming to respond adequately to Auckland’s annual population growth by improving movement through the city as the population grows.
The TBM is expected to break through in September.
The machine is laser guided, remotely operated, and has a diameter of only 32 cm. At its current rate of 3.75 m per hour, it is predicted to complete the 630 m tunnelling project in six months.
The tunnelling will see the machine moving between pre-dug shafts which will be filled in as each section in completed, minimising the footprint of the project.
The larger rail loop project will involve a number of larger tunnel boring machines (TBM), which will be digging twin tunnels for a new station and rail loop and is projected to commence in 2026.
The SRL project will require approximately 16 kms of twin tunnels between the suburbs of Cheltenham and Glen Waverley. Further digging will be required to complete the tunnel from Glen Waverley to Box Hill.
The longest of these twin tunnels will be approximately 6 kms between Burwood and Glen Waverly, a full 4.2 kms longer than the Metro Tunnel project at 1.8 kms.
The variety of ground conditions through which the TBMs will bore is varied enough that multiple machines will be needed to complete the project.
The project aims to have up to 10 custom built TBMs, launching from three locations in the area. The intention is that more machines will complete the project with a tighter turnaround.

The project will be utilising two tunnel boring machines (TBM) which will be shipped over by German supplier Herrenknecht.
The TBMs are each 90 m long, 4 thousand tonnes, and have a diameter of 15.6 m. Similar to Bella, one of the TBMs on the West Gate Tunnel Project.
Pre-tunnelling work has begun, with crews preparing to realign a 300 m section of road to make room for the launching point for the TBMs. Further preparations will involve site surveys and setting up construction compounds in the area.
The Urban Design and Landscape Plan (UDLP) for the project was exhibited in May 2022, and community feedback was considered in the final design stages of the project.
Tunnelling is expected to begin in 2024, and will start in Watsonia. The two TBMs will dig 6.5 km worth of tunnels, 1.9 km longer than the original design for the project. The intention of the project is to move up to 15 thousand trucks off local roads, cut travel times, and increasing open spaces in the area.
The tunnel will be bored beneath the Yarra River, neighbourhoods and a sports centre.
