Petaling Jaya, Selangor, Malaysia

A 193m-high condominium development consisting of a two block 56-storey condominium inclusive of 8 levels of elevated car parking with 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. Value engineering in terms of structural optimisation is done by varying the core and shear wall thicknesses and concrete grades as far as practically possible in order to minimize the need for steel reinforcement yielding significant savings whilst still satisfying the overall building performance requirements such as minimizing the vertical differential axial shortening, lateral building drift and lateral building accelerations amongst others.


Client: Sunway Serene Sdn Bhd

Consultancy Scope: Full Structural Value Engineering


Project Cost: RM250mil.


Project Status: Completed in 2023


Value engineering figures achieved on this project include: -

  • core and shear walls concrete quantity reduced by 9,541 m3 from 37,046 m3 to 27,505 m3

  • core and shear walls concrete wall average thickness reduced from 241 mm to 179 mm

  • core and shear walls steel quantity reduced by 2,057,506 kg from 4,251,076 kg to 2,193,570 kg

  • core and shear walls steel tonnage reduced from 115 kg/m3 to 80 kg/m3

  • reduction of embodied carbon CO2e from concrete of 3,435 tonnes and steel of 3,909 tonnes

  • estimated material savings of RM 10,540,621

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.
