As large size hardwood is becoming more difficult to access, engineers are looking for innovative alternatives such as Fibre Reinforced Polymers (FRP), also known as Fibre Composite (FC).

 

The use of traditional concrete culverts can also be problematic as they can restrict the water flow when debris builds up against the box legs, resulting in scouring both around the crossing and further away along the road as the flood waters seeks an alternative path.

 

In recent years BAC has been developing fibre composite bridge and walkway solutions for new and replacement bridges.

 

• The benefits of BAC’s designs include: 

  • Low weight 

  • Corrosion resistant 

  • High strength to weight ratio 

  • UV resistant 

  • Pest/vermin resistant 

  • Expected service life of 75+ years 

  • Low Maintenance requirements 

 

Design 

​

The bridges are designed in accordance to Australian Standards AS5100 Bridge Design, Aust-roads guide to Road design and European FRP Structural Design and are independent certified by CPEng/RPEQ where required.

 

Our structure consists of beams, cross beams and decking made as one structure.

 

We use our own proprietary software that is engineered specifically for our production methods and innovative materials that has been developed specifically for these bridge applications.

 

Finite element analysis has been conducted on the designs and delivered very good correlation in stresses and deflections to BAC’s software.
