Construction methodology involved deep long trenches often on low volume roads. Clients preference was for the use of barriers however due to road constraints, these were often not able to be installed compliantly, posing additional risk to workers, as well as reducing the amount of work space affecting their productivity.
A complex project to add a supplementary footbridge over State Highway 1 on the Northern Motorway in Auckland. This project requires significant construction adjacent to and over one of New Zealand’s busiest motorways. All whilst ensuring minimal disruption and retained function of the major motorway interchange that the project is dissecting. The end result will be a fantastic and safe shared use facility however not before the challenges of construction through a fully functioning motorway itnerchange are fully overcome.
Since 2017, significant government funding has bene injected into the development (or redevelopment) of housing particularly in dense residential areas of Auckland. This is managed by Kainga Ora and their appointed alliance contractor – Piritahi Alliance – engaged Parallaxx to provide TMP design, TTM consultancy and Traffic Modelling in support of their numerous projects int he Auckland Region.
Renewal of the large diameter watermain called Huia No.1 which has reached the end of its useful life. The watermain was built in the 1940s after World War II. To extend its life it was rehabilitated in the 1980s but now there is need to build a new pipe. Over the next few years, the 17km pipe is being built in sections across West and Central Auckland, in many cased through major intersection and long busy traffic routes.
This project is for Section 11 of the Hunua 4 Watermain project. This takes the pipeline from Market Rd through to Burleigh St in the city. Utilising busy, city streets as the route creates many issues involving high traffic volumes, noise in residential areas, access to businesses and residents, as well as very deep shafts that need protecting.
The Grafton Gully Cycleway project presented a number of challenges – mainly the tight working spaces adjacent to the motorway and the tunnel under Wellesley Street (it was open trenched). The high traffic volumes through this area required us to maintain traffic flows as much as possible
Widening of the Southern Motorway in Auckland over time has pushed State Highway 1 extremely close to adjacent commercial properties in this very constrained corridor. Improved noise protection was called for and due to the already constrained corridor – construction was a challenge to ensure safe working room, and limited disruption on New Zealand’s busiest road.
The DIDP actually describes a suite of projects – encompassing numerous complimentary activities along Auckland’s waterfront. This project might just be one of the most challenging we have ever been involved with – requiring unique solutions, new ideas and significant communication right from tender time. The traffic volumes, coupled with the disruptive work means this project will forever be delicately working in the sweet spot between disruption and productivity.
Network improvements through the Clevedon Area (to and from the Ardmore pump station) are necessary for network growth and resilience. Unfortunately the road network in this area is a series of narrower high speed roads giving little room to accommodate construction concurrent with normal traffic flow.
The final stage of Auckland’s Western Ring Route aiming to connect SH18 with SH1 . This was the first contract of its kind in New Zealand (a ‘Hybrid Alliance’) and Parallaxx were involved from tender time to encourage innovation in the Traffic Management space and ensure the best overall project result.
