That could have threatened the structure that sat atop those piles: columns in the underground parking garage. The building was under construction for more than six years. >> Fast-growing trees close to the foundation of a structure can cause unequal settlement when active tree roots dry out the soil causing differential soil shrinkage. Clues to any of those problems will be clear only after the rescue operation ends, recovery begins and engineers dig all the way to the bottom of the debris pile, Mr. Peraza said. The brickwork was finished up to the sixteenth floor, and the structure was generally encased from the second to the fifteenth floor.
