MORRINSVILLE ROAD
'PEANUT' ROUNDABOUT
Client: Hamilton City Council
Location: Morrinsville Road, Newstead, Hamilton
Date: Feb – May 2026
CONTEXT
As part of part of a four-stage process of fit-for-purpose improvements on this section of SH26, the roundabout construction was the highest priority. This project involved transforming this intersection to improve safety, traffic efficiency, pedestrian accessibility and cycling connectivity along a key arterial corridor.
PROJECT SCOPE
A key component was the delivery of modern multimodal transport infrastructure incorporating shared paths, protected cycle facilities, raised pedestrian crossings, cycle separators, tactile paving and upgraded pedestrian connectivity.
The project also included urban design and landscaping elements such as decorative exposed aggregate concrete, coloured concrete finishes, river boulder features, central island landscaping and streetscape enhancements.
SUMMARY OF WORKS
Physical work began with demolition and clearance on the brownfield site, involving extensive removal of existing pavement, islands and kerbing. Works then moved on to pavement reconstruction, drainage upgrades, kerb and channel construction, asphalt surfacing, traffic signal infrastructure, lighting and landscaping.
PAVEMENT
Pavement reconstruction works including subgrade preparation, geotextile installation, GAP65 subbase construction and asphalt surfacing comprising AC20 and AC14 pavement layers.
STORMWATER AND DRAINAGE
Infrastructure upgrades included new pipelines, raingardens, treatment swales, catchpits, subsoil drainage and filtration systems. These was installed while maintaining existing network functionality.
SERVICE LOCATION / PROTECTION
A major project challenge was the density of existing utilities, which included 33kV and 11kV power infrastructure, gas mains, telecommunications, fibre networks, water reticulation, stormwater and wastewater assets. In coordination with utility providers, extensive investigations, hydro excavation and potholing were required to locate and protect existing infrastructure prior to excavation and construction.
TRAFFIC MANAGEMENT
HCC and NZTA approved temporary road closure enabled Base Civil to accelerate delivery of the works, reduce the project programme from (potentially) nine months to four, and to minimise disruption to motorists and the surrounding community.
COMPLETION
All works were completed in accordance with Hamilton City Council requirements and Waikato Regional Infrastructure Technical Specifications (RITS), one week ahead of schedule.
RELEVANCE
This project demonstrates our ability to work collaboratively to deliver high-quality outcomes for complex urban transport and intersection upgrades.
GREAT SOUTH ROAD ROUNDABOUT
Client: Waikato District Council
Location: Great South Road, Ngaruawahia
Date: February - June 2025
CONTEXT
This roundabout at the intersection of Great South Road and Old Taupiri Road, was part of a broader infrastructure programme to support growth in Ngaruawahia North.
SUMMARY OF WORKS
This roundabout formed the final stage of a multi-phased development that included earlier roading and stormwater upgrades along Festival Way and Galbraith Street.
The intersection, located on a high-volume arterial route and adjacent to the North Island Main Trunk railway, presented multiple constraints requiring precise staging, rigorous traffic management, and close coordination with KiwiRail.
KERB AND CHANNEL
The project included major civil works at the intersection, involving the removal and disposal of old kerb and channel, and the installation of new kerb and channel, with mountable kerbs on the central island.
SURFACING
We removed and disposed of existing pavement surface and reinstated it with a new structure consisting of AP40 sub-base, M4 basecourse, and two-coat chip seal surfacing.
Deep Lift asphaltic concrete (AC) surfacing was applied in high-stress areas, including roundabout approaches and the central circulating lane.
CONCRETE
New concrete works included the construction of over 420 square metres of footpaths and shared paths, as well as concrete splitter islands and tactile paver panels.
STORMWATER AND DRAINAGE
Upgrades included the installation of new stormwater pipelines, new manholes, catchpits, and pre-treatment devices to ensure water quality compliance. Existing services were protected and relocated, following utility location and hydro-excavation.
LIGHTING, SIGNAGE AND ROADMARKING
Streetlighting upgrades included new LED light poles, ducting and cabling, ensuring compliance with AS/NZS standards. We supplied and installed permanent signs and line marking, including roundabout edge markings, centreline, limit lines, and thermoplastic arrows.
LANDSCAPING
Screened topsoil from stockpile was applied to grassed areas to establish an even surface before hydroseeding. Planting areas were prepared with imported screened topsoil, compost, biodegradable Ecowool mulch mat and biodegradable retaining pins.
CONSTRUCTION MANAGEMENT
Given the importance of Great South Road as a strategic detour route for SH1 closures, maintaining two-way traffic flow was critical. We used a five-stage construction methodology, starting with peripheral works and progressing through quadrant-based build-outs. Full closures were limited to overnight and weekend windows for centre works and final surfacing. Traffic management plans were created for each stage.
TIMEFRAME
The project was delivered on a compressed timeline, with physical works commencing in February and substantial completion achieved by the end of April, in accordance with Waka Kotahi and Kainga Ora funding requirements.
ENGAGEMENT
Our team worked closely with WDC staff, KiwiRail, utility providers, local residents and road users throughout the project. Focused collaboration, planning, and quality execution led to the successful upgrade of this intersection with minimal disruption and significant long-term benefits for the Waikato District.
RELEVANCE
This project showcases our ability to minimise disruptions and manage expectations of residents and road users, and shows we can work quickly and efficiently under time pressure.
CLAUDELANDS EAST
Client: Hamilton City Council
Location: Claudelands, Hamilton East
Date: October-November 2022
CONTEXT
Heaphy Terrace and Grey Street between Brooklyn Road and Claudelands Road was a known high-risk area for pedestrians and cyclists.
SUMMARY OF WORKS
This intersection upgrade for Hamilton City Council was completed in four weeks - one week ahead of schedule. The 300 metre long construction site straddled the Grey Street level rail crossing of KiwiRail’s East Coast Main Trunk line.
DRAINAGE IMPROVEMENTS
We added seven new catchpits and associated pipework in the pavement and kerb lines around existing services, and adjusted manhole lids to suit the new levels.
SERVICES RELOCATION
We relocated traffic signal ducting, installed new ducting, and positioned 30 new signal poles.
KERB AND CHANNEL
We removed existing kerb and channel and installed new kerb and channel in existing pavement. This included depressed kerb for crossings, pinned-on median kerb, and 600mm wide dish channel.
CONCRETE WORKS
We constructed new asphalt and coloured exposed aggregate concrete footpaths. We installed six large raised speed platforms (RSPs) with thermoplastic marking, and positioned new lighting poles, signs and bike racks.
SURFACING
Our surfacing team milled and resurfaced over 5,000 square metres of asphalt and fully reconstructed 1,057 square metres of pavement.
MANAGING DISRUPTION
We worked with HCC and WDC to create bus diversion routes around the construction site and ensure bus stops remained accessible. We maintained pedestrian and vehicle access to businesses by providing access to nearby parking, and placed signage on pedestrian routes to let people know businesses were still operating while the site work progressed.
PROTECTING THE ENVIRONMENT
Our permitted works were in a location where stormwater could potentially discharge directly into the Waikato River. We put strict environmental control measures in place - including stormwater catchpit bags and silt socks around catchpits - so that no site sediment runoff entered the natural waterway.
WORKING NEAR THER RAIL CORRIDOR
Temporary fencing, pedestrian footpaths across the rail crossing and traffic controllers monitoring, ensured the rail corridor was inaccessible to vehicle and pedestrian traffic.
SUSTAINABLE PRACTICES
All milled asphalt was recycled and used on another project.
RELEVANCE
The project demonstrates our ability to manage the logistics of urban roadworks and drainage upgrades, while protecting the surrounding natural environment. It shows we can reduce work duration by managing road closures and maintaining traffic flow.
