🚧 HARRIS ROAD | EMERGENCY RESPONSE & REINSTATEMENT 🚧
A challenging project, quick thinking and a great example of collaboration!
Following a significant rainfall event, Harris Road experienced extensive erosion beneath an existing gabion retaining wall, with undermining reaching depths of up to 1.7 metres in places.
Mills Albert was called upon to mobilise quickly, working collaboratively with Porirua City Council and ENGEO Consultants to develop and deliver a practical design-and-build solution.
And this was certainly no ordinary repair!
With challenging access, a confined stream environment and an existing structure requiring careful support, our team had to think quickly on their feet, adapt to changing conditions and ensure the design and construction methodology worked hand in hand.
Environmental and ecological considerations were a key part of the planning and delivery. Working within an active waterway required a carefully considered approach to managing stream flows, protecting the surrounding environment and minimising disturbance during construction.
Our construction team worked closely with our in house environmental and ecological specialists, to ensure practical engineering solutions could be delivered while appropriately managing the sensitivities of the stream environment.
The works involved:
🔸 Temporary works and structural propping
🔸 Temporary stream diversion and water management
🔸 Complex formwork and concrete construction
🔸 Reinstatement of support beneath the existing retaining wall
🔸 Environmental and ecological planning integrated into construction activities
This project was a great example of what can be achieved when practical experience, engineering expertise and environmental awareness come together.
A big thank you to Porirua City Council and ENGEO Consultants for their collaboration and support throughout the project.
A special thank you also goes to the residents of Harris Road for their patience, understanding and cooperation while these works were undertaken. Your support was genuinely appreciated.
And of course, a huge shout-out to the Mills Albert team and our internal specialists for their hard work, adaptability and commitment to finding solutions and getting the job done.
With the works completed, it was only fitting to bring our fancy BBQ to site for a well-earned feed! 🌭🔥
Great teamwork, great people and a great result! 👏
