LOT 349 SENTRAL SUITES

Brickfields, Kuala Lumpur, Malaysia

A 162m-high condominium development consisting of a three block 46-storey condominium inclusive of 2 levels of basement car parking and 9 levels of elevated car parking with a 2650mm thick reinforced 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 2650mm thick dual-cast RC 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.

VERTICAL AND LATERAL LOAD PATHS AND SHEAR WALL OPTIMISATION

Value engineering figures achieved on this project include: -


  • core and shear walls concrete quantity reduced by 8,276 m3 from 33,651 m3 to 25,375 m3

  • core and shear walls concrete wall average thickness reduced from 266 mm to 202 mm

  • core and shear walls steel quantity reduced by 1,702,760 kg from 3,842,314 kg to 2,139,554 kg

  • core and shear walls steel tonnage reduced from 114 kg/m3 to 85 kg/m3

  • reduction of embodied carbon CO2e from concrete of 2,979 tonnes and steel of 3,235 tonnes

  • estimated material savings of RM 9,671,324


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.
