SLURRY-TRENCH CONSTRUCTION FOR BASEMENT WALL OF WORLD TRADE CENTER

NEW YORKS CITY'S WORLD TRADE CENTER PROJECT IN MANHATTAN HAS A HUGE BASEMENT 70FT. DEEP AND 11 ACRES IN AREA. IN BUILDING THE EXTERIOR WALL FOR THIS HOLE, THE SLURRY-TRENCH METHOD WAS EMPLOYED. THIS TECHNIQUE WAS CHOOSEN BECAUSE CONVENTIONAL CONSTRUCTION METHODS WOULD HAVE BEEN DIFFICULT. AMONG THE PROBLEMS WERE (1) SUBSURFACE OBSTACLES SUCH AS OLD BURIED WHARVES, (2) DEEP LOWERING OF THE WATER TABLE OUTSIDE OF THE SITE HAD TO BE AVOIDED, (3) IT WAS DESIRABLE TO LEAVE GAPS IN THE WALL DURING UTILITY RELOCATION, AND (4) A WATERPROOF WALL EXTENDING DOWN INTO BEDROCK (AS PROVIDED BY THE SLURRY-TRENCH METHOD) WOULD MEAN A NONBUOYANT BASEMENT THE SLURRY-TRENCH METHOD AS APPLIED TO THIS PROJECT IS DESCRIBED AND THE ADVANTAGES OF THE METHOD ARE PRESENTED. BUILDING DEMOLITION OCCURRED SIMULTANEOUSLY WITH THE WALL CONSTRUCTION. COMPLETION OF THE WALL IN EFFECT SEALED OFF THE BASEMENT FROM THE OUTSIDE EXCAVATION CONTINUED INSIDE, WITH ONLY PUMPING REQUIRED TO REMOVE THE EXISTING ENTRAPPED WATER.
