Diaphragm Wall & Barrette Piles

22,000m2 of diaphragm wall and barrette piles to form the permenant box for the new Circle Line Iterchange Station at Serangoon Central. The contract requires two load bearing tests on the barrettes to test end bearing and skin friction. The load on the station comes from a commercial development above and requires penetration in to the bed rock.
