Wangsa Maju, Kuala Lumpur, Malaysia

A 154m-high condominium development consisting of a two block 46-storey condominium inclusive of 9 levels of basement and elevated car parking, a facility level and a 2200mm 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 2200mm 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.

Client: Sunglobal Resources Sdn Bhd

Consultancy Scope: Full Structural Alternative Design Engineer


Project Cost: RM200mil.


Project Status: Completed in 2023


Value engineering figures achieved on this project include: -

  • core and shear walls concrete quantity reduced by 2,048 m3 from 19,284 m3 to 17,236 m3

  • core and shear walls concrete wall average thickness reduced from 177 mm to 159 mm

  • core and shear walls steel quantity reduced by 1,771,622 kg from 3,394,238 kg to 1,622,616 kg

  • core and shear walls steel tonnage reduced from 176 kg/m3 to 94 kg/m3

  • mega columns concrete quantity reduced by 774 m3 from 3,942 m3 to 3,168 m3

  • mega columns steel quantity reduced by 737,803 kg from 1,020,393 kg to 282,590 kg

  • reduction of embodied carbon CO2e from concrete of 1,016 tonnes and steel of 4,768 tonnes

  • estimated material savings of RM 7,256,658 (core and shear walls) & RM 2,803,652 (mega columns)

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.
