Specialised Structures

In order to demonstrate our track record in our fields of expertise, we have summarised a selection of our projects, which have been recently completed or which are ongoing.

For each of the selected projects we provide a descriptive summary of the project itself, as well as outlining the nature of our involvement and our responsibilities in its execution. We also provide some general project data. The projects are of a diverse nature, and include large stadium structures, buildings, bridges and tunnels.
We are proud of the diversity of skills and expertise, which we can offer to our clients.

  • Overall Length : 343,5 m
  • Overall Width : 67,0 m
  • Foundations : Ø 1 829 mm and Ø 1 219 mm cased piles, up to 70 m long with a free height of 22,0 m,  excavated and concreted under polymer.  Berthing forces are resisted through pile flexure.  Reinforced concrete pile caps measuring 2,50 x 2,50 x 0,59 m
  • Superstructure : Composite concrete deck consisting of 1,70 m deep pre-tensioned T-beams, spanning 21 m and weighing 55T acting compositely with a 350 mm thick in-situ deck slab.  There are three 21 m spans, which are partially continuous for dead load.  The T-beams are in turn supported by and monolithically connected to 2,0 m deep pre-tensioned spine beams weighing 60T and spanning 10 m between the piles.  The spine beams rest on the pile caps.  The pile cap to spine beam connection is pinned in a longitudinal direction to allow for settlement differentials and temperature movements, while being rigid transversely in order to allow moment transfer from the deck to the piles for the purposes of resisting berthing forces.
