McConnell Dowell pleased to announce that Gisborne District Council has awarded the Stage Two of the upgrade of Gisborne Wastewater Treatment Plant to McConnell Dowell.
Located in New Zealand’s North Island, this project involves the construction of a secondary clarifier and tertiary treatment facilities to treat domestic wastewater after the existing biological trickling filter. This new infrastructure will be more resilient in the event of natural disasters and will improve water quality.
This is an exciting project for the McConnell Dowell team to continue to build on our extensive track record in wastewater plant construction throughout New Zealand, Pacific, Australia and South East Asia.
McConnell Dowell worked in collaboration with Gisborne District Council and designers BECA to ensure the project’s key requirements around performance and social outcomes were met within budget.
McConnell Dowell Managing Director for New Zealand and the Pacific Islands, Fraser Wyllie says; “We are excited to work for Gisborne District Council to deliver an upgraded and more resilient infrastructure which responds to the region’s growth”.
Stage two includes construction, installation and commissioning the following new processes:
- New clarifier pump station to transfer the effluent from the biologically trickling filter (BTF) to the new clarifiers
- Ground improvements including engineered rafts
- Lamella type, secondary clarification to remove the gross solids from the effluent
- Scum and sludge underdrain removal system
- Disc-cloth type tertiary filtration system for effluent polishing prior to disinfection
- An in-channel type, ultra-violet disinfection system
- New screw presses for dewatering
- New recycled effluent system which will be used to provide wash water for process related equipment
- Civil works (pipelines, drainage, stormwater, stormwater treatment, pump station, chambers, roadways, hardstands etc)
- Structural works (concrete pads, steelwork platforms etc)
The work will commence in early September 2021, with completion due in Mid-2022.
McConnell Dowell is pleased to announce that construction on the new Ports of Auckland Outfall Upgrade Project will begin in late 2021.
The project team will construct the last and most challenging section of the Stanley Street catchment network upgrade. The upgrade will mitigate future flooding risks in the area and importantly for the Britomart Train Station.
A new 270-metre inverted siphon pipeline will be installed using a three-metre in diameter micro-Tunnel Boring Machine (m-TBM). The outfall alignment will run under Quay Street behind the Ports of Auckland (POA), near Freyberg Wharf. The old stormwater culvert will also be repaired and reinstalled. Once complete, the new outfall will increase the stormwater network’s capacity and improve the resilience of downtown Auckland’s infrastructure.
This stormwater outfall upgrade will draw on McConnell Dowell’s extensive track record in marine outfall construction using trenchless methodologies.
Work on this project includes:
- Service relocation works
- Piling works for both the outlet and inlet shafts
- Excavation works for both shafts
- Tunnelling under Quay Street to a maximum depth of 20 metres
- Chamber and outfall construction
- Culvert strengthening
McConnell Dowell is pleased to form part of the Alliance that will deliver the detailed design and construction of the Westhaven to Akoranga section of the Northern Pathway.
Following the announcement from the Minister of Transport (Friday 4 June 2021), we are now able to confirm that the preferred option for the Northern Pathway, Westhaven to Akoranga is a separate structure for walking and cycling alongside the Auckland Harbour Bridge, protecting its heritage and structural integrity. Alliance partners McConnell Dowell, Aurecon, Fulton Hogan, HEB Construction and Freyssinet, have been actively working on a preferred solution that is fit for a growing Auckland.
The Northern Pathway Westhaven to Akoranga project will provide a seamless, dedicated walking and cycling link between central Auckland and the North Shore. It will connect with existing local paths to extend the region’s walking and cycling network providing people with real choice in the way they travel and significantly improve climate outcomes.
McConnell Dowell's New Zealand and Pacific Managing Director, Fraser Wyllie says this project will enable a modal shift on this strategic connection for Tamaki Makaurau.
"McConnell Dowell has successfully delivered complex infrastructure projects with our customers and communities across Aotearoa for the past 60 years. We are excited to partner with Waka Kotahi and our Alliance project partners to deliver the Northern Pathway project."
Alliance Project Director, Hugh Milliken, says he is feels privileged to be involved in such a transformative project for the city and shares the excitement of the Alliance project team.
“I’m proud to lead the Alliance to deliver this project which will provide an important strategic connection enabling people to travel across the harbour on foot and on bikes for generations to come.”
The Northern Pathway, from central Auckland to the North Shore, is split into three connected sections for delivery:
- Westhaven to Akoranga, Te Ara Pae Moana (harbour bridge component) and land component between Sulphur Beach Reserve and Akoranga.
- Akoranga to Constellation Drive.
- Constellation Drive to Albany is under construction as part of the Northern Corridor Improvements project.
Once complete, the Northern Pathway will provide a fully separated pathway between Westhaven and Albany with local entry and exit points.
The Midland Junction Alliance (MJA), an alliance comprising of McConnell Dowell, Georgiou Group, Arcadis and BG&E, has been named preferred proponent to deliver the new METRONET Midland Station in Western Australia.
Work includes decommissioning and demolishing the existing 53-year-old train station and the design and construction of a new facility between Helena and Cale streets.
The station's contemporary design will incorporate three platforms catering for up to six-cars, a publicly accessible pedestrian overpass connecting both sides of the railway, a bus interchange and cycling facilities.
McConnell Dowell Managing Director, Jim Frith said McConnell Dowell are excited to be partnering with the Public Transport Authority of Western Australia (PTA) and the alliance partners to deliver this important project as part of the METRONET program.
“McConnell Dowell has successfully delivered complex infrastructure projects with our customers and communities for the past 60 years. We are proud to be to working with PTA and our partners to deliver this exciting piece of infrastructure for Perth and support the ongoing development of the skills and expertise in the local construction industry.”
Alliance General Manager, Leonard Munday said he is proud to be leading the delivery of the Midland Station
“I am excited and look forward to working with PTA on a project that will expand connections, set a platform for invigoration and importantly, leave a legacy for the Midland community”
Once open, the new station is expected to have 3,300 daily boardings, growing to 3,700 in 2031.

McConnell Dowell is pleased to announce that the Wynyard Edge Alliance won the Engineering New Zealand, Arthur Mead Award for Engineering Excellence for Projects greater than $10 million for the 36th Americas Cup infrastructure project. The awards night at the Royal New Zealand Yacht Squadron in Auckland was attended by many members of the WEA project team lead by Kurt Grant (McConnell Dowell) who accepted the award on behalf of all that were involved with this outstanding project.
The Wynyard Edge Alliance delivered the stage for the 36th America’s Cup and a waterfront consisted of McConnell Dowell, Downer, Beca, T+T, Auckland Council, Panuku and MBIE.
The Alliance was recognised for numerous innovative materials and techniques including:
- pre-casting of the wharf and breakwater components and transporting them to site by barge, saving numerous truck trips through downtown Auckland,
- laying the groundwork for future development of the Wynyard Point land on which decades of heavy bulk fuels had been stored,
- provided a language skills programme for the construction workers that has assisted the workers to confidently move to other construction projects as well as engaging deeply and successfully with stakeholders and partners in a highly sensitive environment.
Most importantly, they got it all done in time for the 36th America’s Cup races to begin, meeting all of the project milestones and completing the project with 1.1 million worker hours LTI free.
Congratulations to everyone that worked on this outstanding project, deemed a Beacon project by MBIEs Construction Sector Accord, helping Emirates Team New Zealand win the 36th Americas Cup.
