Kuala Lumpur (Malaysia) – For the 348 Sentral project a shopping mall and three high-rise towers with up to 31 floors, which will house a hotel and residential units, are under construction in Malaysia’s capital. MRCB Engineering contracted BAUER Malaysia Sdn.Bhd. to plan and construct the foundations and underground floors on a turnkey basis.

The works started in May 2009 and comprise the installation of some 7,000 m² of diaphragm wall and 161 bored piles in 1200 mm and 1500 mm diameter.

A notable feature of the pit construction is the employment of two different techniques – top-down and bottom-up.
 

The top-down area includes the 161 piles, 58 of which with plunge-in-columns to support the top down slab. In the bottom-up area the 800mm thick diaphragm wall is retained by 300 temporary anchors and pre-stressed steel stiffening struts.

The special feature of this is that the struts tension against the permanent ceiling slabs of the basement floor, constructed by the top-down method, thus minimizing the strut lengths.
