SYNOPSIS

Probably one of the deepest underground basement ever constructed for a high-rise building in downtown Kuala Lumpur, a 37m-deep excavation was conducted for the upgrading of the MAS Building, on Jalan Sultan Ismail. The construction started with the demolition of the front podium of approximately 1,700m2 in area. The semi top-down construction method with kingposts was adopted akin to a strut-slab system, in place of the conventional steel strut and walers system.

This system has been proven effective in controlling the retaining wall deflections and adjacent ground deformations, while attaining a timely construction period.

The talk will outline the key construction challenges involving removal of the existing 450mm CBPs, and 1,000mm diameter building piles; installation of new CBPs ranging from 600mm to 1,350mm in diameter, of an average depth of 45m; 3,000mm diameter foundation bored piles of an average depth of 70m, and its load test performance; sequential ring slab construction and excavation in a semi top-down fashion; pre-loading against the CBP wall along St. Mary building. The problems which arose during the construction stage and the performance of the underground structure throughout construction will be discussed.
