An innovative solution using Dramix 5D steel fibre reinforcing to reduce the amount of conventional reinforcement required for shear, bending moment and crack control. The solution proved to be quicker, easier and more cost effective than the traditional more labour intensive option.
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.
