McConnell Dowell is pleased to announce the award of the St Marys Bay and Masefield Beach Water Quality Improvement Project by Auckland Council’s Healthy Waters department.
This project continues to build on McConnell Dowell’s extensive experience constructing ocean outfalls. Our award-winning trenchless technology reduces the amount of trenching required in the landward section and disruption to nearby stakeholders.
It also minimises impacts for people travelling through the area – important considerations in confined residential environments and Auckland’s busy transport network.
The St Marys Bay and Masefield Beach Water Quality Improvement Project is one of the first and largest Water Quality Targeted Rate funded projects to get underway in Auckland and will reduce the number of overflows from an average of 100 a year to an average of 20.
McConnell Dowell Managing Director for New Zealand and the Pacific Islands, Fraser Wyllie says that “McConnell Dowell has considerable expertise in this area having constructed all of the largest marine outfalls in New Zealand. We are proud to be able to help improve water quality in our harbours and beaches and help provide a better life to communities. “
The work will involve:
- Installing almost two kilometres of new pipeline
- Only 25% will be installed using traditional dig and lay methods
- Over 50% of the alignment will be tunnelled (1120m) using a brand new Herrneknecht TBM
- And 1.8m ID reinforced concrete pipes will be jacked into place
- The final 25% of pipeline will be constructed from HDPE and will form the outfall which will be joined in Kaiaua then towed to the city before it is lowered into place on the seabed in a controlled sink
Construction will commence in January 2020 and is scheduled to be completed by late 2021.
Waka Kotahi NZ Transport Agency held an official event to mark the start of construction for the Old Māngere Bridge project at the Waterfront Reserve on Friday 22 November.
Representatives from the Transport Agency, McConnell Dowell, Te Ākitai Waiohua, local politicians, Police, walking and cycling advocates and members of the community gathered to celebrate the start of work.
The speakers all acknowledged the close relationships that have developed, the shared journey everyone has been on and the pleasure of reaching this milestone.
Fraser Wyllie, Managing Director of McConnell Dowell’s New Zealand and Pacific business noted “it was great to see so many people passionate about improving infrastructure in their communities and we are proud to be helping deliver such a striking new bridge for them.”
Caring for the harbour, the environment and people during construction was also a shared theme. “Being good stewards of the Manukau Harbour, keeping everyone safe and being valued members of the local neighbourhood is important to the team,” says Project Manager Phil Kearney.
McConnell Dowell would like to invite the community down to Waterfront Reserve on Saturday 30 November, from 10am to noon to meet the team. “We will be there to answer questions and tell people about the upcoming work like the deconstruction of the old bridge which starts in early 2020. Bring the family and come down for a sausage, a chat and some entertainment for the kids.
The replacement bridge will be a critical community connection and an additional link in Auckland’s walking and cycling network when it is completed in early 2022.

The McConnell Dowell Decmil Joint Venture has been awarded the contract to design and construct the Mordialloc Freeway in Melbourne’s south east.
The 9-kilometre Freeway will link the Mornington Peninsula Freeway at Springvale Road in Aspendale Gardens to the Dingley Bypass in Dingley Village, creating a continuous freeway from Frankston To Clayton.
With more than 75,000 motorists predicted to use this route daily by 2031, the Freeway will be vital to ease congestion and improve safety by removing 13,000 trucks from local roads.
As part of the project, bridges will be built over Springvale, Governor, Lower Dandenong and Centre Dandenong Roads, along with new freeway entry and exit ramps.
A bridge will also be built over Old Dandenong Road to keep it open for Dingley Village residents, and a twin bridge will be built over sensitive wetlands to ensure rainfall and natural light reaches vegetation below.
A new shared walking and cycling path will also be constructed along the entire length of the Mordialloc Freeway, to ensure safe and reliable journeys for members of the public enjoying more active forms of transport.
Motorists using the Mordialloc Freeway can expect quicker and safer and journeys, with north and southbound traffic separated and road safety barriers installed along the inside and outside of each carriageway.
McConnell Dowell is pleased to be partnering with Decmil to deliver this unique and vital part of Melbourne’s road infrastructure, said Jim Frith, Managing Director of McConnell Dowell Australia. “We have a strong team in place to deliver a complex design and construction program, with innovative solutions to building in a sensitive environment.”
Construction of the Mordialloc Freeway will create 400 jobs, which will include 10% of total labour hours allocated to training apprentices, trainees and cadets, building much needed skills within the industry.
Decmil Managing Director, Scott Criddle said, “Decmil is very pleased to be partnering McConnell Dowell and Major Road Projects Victoria on another largescale transport infrastructure project. Our project team working on the early works package will now continue into the main works package to progress the project and delivery programme”.The Mordialloc Freeway has been funded by the Victorian Government and is being delivered by Major Road Projects Victoria. It is due to be completed by late 2021.
In addition, the Joint Venture is committed to sourcing at least 96% of material and employment locally, benefiting the local community and broader economy.
The first major milestone was reached on the Puhinui Station Upgrade recently with the successful deconstruction of the central station ramp during a rail closure recently. The joint venture between McConnell Dowell and Built Environs has developed an early works strategy for the Puhinui Train Station Upgrade project with safety at the core of the construction. This is imperative as a large portion of work needs to be carried out over the live tracks and around the electrified lines in the rail corridor.
All together 350 tonnes of concrete were also removed during the controlled demolition stage which was finished in mid-October 2019.
The first requirement for this stage of the work was to support the three footbridge ramps that lead to the overbridge and train station. Scaffolding was erected to support these segments before each were cut using a wire saw and carefully removed over the tracks during a ‘Rail Block of Lines’ or track closure.
The project team continue to remove all the existing platform assets to clear the way for the next stage of the construction and have begun piling the station’s foundations.
A 50-tonne drilling rig is installing 32 bored piles, some over 30m deep, to form the foundation for 23 pile caps to support the station structure.
The next milestone for the team is the installation of a protection shield over the track. The shield is an innovative new methodology to maintain safe access and egress for staff in and out of the rail corridor, allowing allow work to continue safely without delay or disruption to rail operations.

McConnell Dowell is pleased to announce the award of the Old Māngere Bridge Replacement project by the New Zealand Transport Agency.
The project includes the demolition and complete removal of the 250 m long Old Māngere Bridge that was originally opened in 1915 and the construction of a new shared walking and cycling bridge between the ends of the existing causeway. The new 300 m long bridge features a central 60 m span in structural steel together with nine approach spans in reinforced concrete.
The replacement bridge will provide up to 6.5 m of clearance for vessels to pass underneath and will reinstate a walking and cycling link between the communities of Onehunga and Māngere Bridge, which has been restricted since the old bridge closed in late 2018. The new bridge will provide key recreational space for people to sit and enjoy the views of the surrounding landscape or those who enjoy fishing in the Manukau Harbour.
McConnell Dowell Managing Director for New Zealand and Pacific, Fraser Wyllie welcomes the announcement, saying
“McConnell Dowell has a strong track record of delivering iconic and multi-award-winning bridges such as the Waitaki River Bridges, Lower Hatea River Crossing, SH1 Russley Road’s Memorial Road Bridge, and Kawarau Falls Bridge.
We look forward to working closely with the New Zealand Transport Agency to deliver the communities of Māngere Bridge and Onehunga an iconic bridge.”
