Creative concrete formwork

Customer: Dominion Constructors
Project: Creative Concrete Formwork
Published: January 2015

Having worked together with Dominion Constructors for many years on electrical projects, the team at Jackson Electrical Industries was approached in the early design stages regarding the usage of Jackson’s concrete moulding design experience and CNC manufacturing facilities. The objective was to turn a loosely discussed architectural concept into a stunning façade, located in the middle of the rapidly changing face of Nugent Street in Newmarket. Just another successful keystone project for the Dominion & Jackson teams.

In order to construct the façade for Aspect Furniture System’s new office building, Dominion Constructors commissioned Jackson to create a complex set of formwork. This would allow the intricate Voronoi pattern to be poured in situ, in just a single stage – using a special concrete mix developed by Dominion particularly for this project that later on won an award at the NZ Concrete Industry Award Ceremony earlier this year.

This methodology involved building large blocks to generate a cavity into which the concrete was pumped from the bottom to a total height of three stories.  A total of 26 ‘modules’ were constructed from multi-axis machined polystyrene with form-ply tool-faces to give a high quality mould surface, in sections that could be manoeuvred into place by hand.

Jacksons 3D CAD modelling, 5-axis CNC machining services were combined with an outside-the-box design approach to meet with project outcome, timeline and budget expectations.

Additionally a large scale jigsaw puzzle template was machined to create a 1:1 layout guide for the modules. The tooling was put together within weeks to the design prepared by Jasmax and HLK Jacob.

This finished project has been unveiled with a big two thumbs up from Nugent Street locals and passers-by alike. Another score on the board for the architectural use of concrete, a process that has been rumbling away in the background for decades – and recently seen a large local upturn due to exposure and awareness growing of what is available and achievable as turn-key solutions here at home in New Zealand.
