A 12m section of the Waiwaka Terrace stormwater culvert’s concrete roof collapsed and a section beneath the road also showed signs of distress. This project is to repair and replace a 60m section of the culvert. Status: Live
We require use of private property so that we have enough room for the machinery that’s required for the repairs. We’ve offered what we think is reasonable
monetary compensation and the landowner has come back with what they think is reasonable compensation, and we’re now in arbitration to come to an agreement.
This process isn’t unusual.
From March to September 2022.
An estimated $6 million, $2.5m of which is coming from the Government’s Covid-response fund for shovel-ready projects.
The cost reflects the size and difficulty of the job, mostly due to the depth that we’ll be working at. A land purchase is also part of the cost.
It will be closed for three weeks when we have people working on the section beneath the road itself. When we move to the section beneath a private driveway, the
road will reopen but there’ll be a speed limit in place.
Yes, all householders will have access to their houses. Those at the end of Waiwaka Terrace, from house numbers 22 to 32A, will have access only from Northgate
during the three-week closure of Waiwaka Terrace.
We expect that nearby houses will hear and feel vibrations when we are installing new trench walls in the first few weeks of stage two. This will be only during work
We’ll also have pumps operating the stormwater and sewage services throughout the works period, which might be heard by nearby houses. We apologise for any
disruption that this causes.
After we were notified of the failure we commissioned an investigation to determine the extent of the failure and have worked on a plan for the best way to repair the
site. It’s a tricky repair because of the culvert’s depth (4-7m deep), the restricted working space, poor ground conditions, and the need to keep both the sewer and the
stormwater systems operating during the repair.
We will put emergency measures in place to keep the stormwater and sewage flowing.
It’s approximately 40 years old.
We don’t know what has caused it or when the failure happened. It could be heavy-vehicle movements on the right-of-way, earthquake damage, construction related
or something else.
The old New Plymouth City Council files on this asset labelled it as a pipe, not a rectangular concrete culvert.
Not to our knowledge.
No, it hasn’t.
No, they are not.
