ABSTRACT
Muzium Negara MRT station was constructed within 16m of the National Museum, a historically significant building in Kuala Lumpur. The 27m deep station excavation was constructed using diaphragm walls and top-down method. The museum building is founded on shallow footing in Kenny Hill Formation. Built in the 1960s, the building may have had previously undergone some degree of settlement apparent from a series of upgrading works over the years before the station box construction. It was therefore considered it would be more sensitive to ground movements making the challenge of controlling the impact of construction-induced settlement even greater. This paper presents the actual performance of the settlement sensitive heritage building responses to a deep excavation carried out in close proximity.
