The works comprised site formation, mini-piling and superstructure construction.

Environmental Concern The site were surrounded by the Sha Lan Villa and the Tung Wah Group - Wu York Yu Old Aged Home. Construction dust arising from exposed dusty materials, drilling, rock-breaking and traffic on the haul road were the major concern of environmental pollution to these nearby residents.
