In the red-hot New Zealand construction market, reducing the time to fix and tie steel reinforcing can provide major benefits to a construction programme. Calibre Consulting Engineers utilised Dramix 5D 65/60 BG fibre to redesign this 900mm deep, 1000m2 raft slab, resulting in the elimination of a significant volume of conventional reinforcing. The combined solution (fibre + conventional reinforcing) provided equivalent structural performance and crack control with approximately 40% less conventional steel, all designed in accordance with NZS3101. The revised design was significantly faster to construct and approximately 10-15% cheaper than the original design.

Schenk facility in Jandakot Western Australia is not your usual commercial shed, there’s pits, services, and major equipment that requires careful consideration. The engineers on this project, have done an outstanding job in considering all the client’s requirements. Most of the internal slabs are constructed from BOSFA’s, tried and tested Dramix 3D product with a slab thickness of 200mm to accommodate the heavier than normal loads.

There are two large sections internally that required additional detailing due to the sensitivity of the machines being used, for this the engineers adopted a Dramix 4D Combi Slab. The combi slab allows for larger fully restrained slabs to be poured with no jointing, no saw cuts and no dowelled joints.

McVeigh Consulting again specified a “Seamless” Dramix 4D Combi Slab for the 22,000m2 Container Park to handle the huge loads from the massive forklifts and stacked containers.
Dramix Jointless slabs were used for the 15,000m2 internal warehouse as well.
And on top of that Dramix was used in the Footings throughout the facility too.

Constructed back in 2012, there are 4 major intersections between Karratha and Dampier. Each intersection constructed using a concrete slab reinforced with Dramix 3D fibres. These intersections are noted to have between 14,000 – 20,000 vehicle movements per day ranging from standard vehicle loads to major road train loadings. So if you’ve ever wondered if those little fibres can handle the load, here’s a great example of yes they can.

Built in 2016 this truck stop is located in Karratha, North West Western Australia. The facility is located on the North West Coastal Hwy, servicing many travellers and heavy haulage vehicles in the area.

Cockburn Shopping centre upgrade was a top down construction method, fairly new to Perth back in 2013 / 2014 and designed via Airey Taylor Construction. So, it was very pleasing that ATC adopted a fibre solution for the carpark basement slab on this project. It’s a great example of SFRC and is easy to access should you like to see how well a Dramix SFRC slab performs.

A Combi Slab (steel fibres + mesh or bar reinforcing) solution was used for the Internal Warehouse Slabs, the External Pavements as well as Rail Track Slab.

Dramix 4D 65/60BG at varying dosages was combined with conventional bar reinforcing for the track slabs and various mesh options for the internal slabs and external pavements.

 

Tomkins Commercial and Industrial Builders recently completed the new Distribution Facility for Miele appliances at Brisbane Airport. Tungsten Structures engineers worked closely with BOSFA and Menard Oceania to design this facility as a Dramix fibre only Slab-on-Piles using a CMC piling system.

Placed back in 2008 this slab is utilised at the Komatsu facility in Perth. These types of slabs come under enormous stress from the equipment loading on the slabs.

Placed back in 2005 this slab is still in use and standing up to the punishment of a mining slab.
Mining workshop slab was designed for heavy mining machinery and jacking loads.

Placed back in 2008 this slab is utilised at the McMahons facility in Perth. These types of slabs were designed for their heavy machinery maintenance workshops.
