Bukit Bintang, Kuala Lumpur, Malaysia

A 233.75m-high condominium development consisting of a 63-storey and a 50-storey condominium inclusive of 4 levels of basement car parking and 13 levels of elevated car parking and facilities with a 2000mm thick post-tensioned (PT) concrete transfer floor. The building superstructure consists of RC flat slabs, RC core walls and RC shear walls within the residential units offering a superior architectural product without any structural protrusions whatsoever. These shear walls are subsequently founded upon a structurally efficient 2000mm thick dual-cast PT transfer plate which separates the residential floors from the elevated car park and facility floors beneath, transferring both the vertical and lateral load functional framing systems. Lateral stability in the X-direction is provided by the longer dimension of the coupled core wall whilst lateral stability in the Y-direction is provided by the shorter dimension of the coupled core wall and virtual outriggers at the transfer levels 5 and 36 onto RC shear walls.

Client: BBCC Development Sdn Bhd

Consultancy Scope: Full Structural and Civil Engineering

Project Cost: RM400mil.

Project Status: Completed in 2022


Value engineering figures achieved on this project include: -

  • core and shear walls concrete quantity reduced by 1,910 m3 from 17,967 m3 to 16,057 m3

  • core and shear walls steel quantity reduced by 1,005,841 kg from 2,468,474 kg to 1,462,633 kg

  • core and shear walls steel tonnage reduced from 137 kg/m3 to 91 kg/m3

  • slab concrete volume and steel tonnage reduced

  • reduction of embodied carbon CO2e from concrete of 688 tonnes and steel of 1,911 tonnes

  • estimated material savings of RM 7,776,847

Often in our value engineering exercises, the factor of safety of the building is increased. This is because the building is only as strong as its “weakest link”. Thus in simple terms, the value engineering exercise increases the capacity of the “weakest link” and reduces the capacity of the “stronger links”. The graph of capacities with respect to demands are presented hereafter with respect to the storeys that the building carries.
