Our Engineers have been involved in some of the largest Civil Infrastructure projects in the World; from the first segmentally erected cable stayed bridge in the world (Sydney, Australia) to the standard pre-stressed beam and plank bridges, we are skilled in the design of segments, beams, abutments and approach slabs.

Our tunnelling knowledge extends to both NATM and TBM methods of tunnelling with specific experience on both the largest earth pressure balance tunnel Boring Machine in the World (Airport Link Brisbane) and the fastest TBM in the World (Legacy Way Brisbane). If you have any requirements in either field, please don’t hesitate to contact us.
