SUNWAY BELFIELD RESIDENTIAL TOWERS 1 | 2 | 3
Kuala Lumpur, Malaysia
A three block 56-storey 205.9m-high tower development inclusive of 2 basement levels and 9 levels of elevated car parking and a 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 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.

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 243 m3 from 9,381 m3 to 9,138 m3 (B2 – L5) and by 582 m3 from 29,238 m3 to 28,656 m3 (L5 – L53A)
core and shear walls concrete wall average thickness reduced from 248 mm to 241 mm (B2 – L5) and from 176 mm to 173 mm (L5 – L53A)
core and shear walls steel quantity reduced by 208,518 kg from 994,386 kg to 785,868 kg (B2 – L5) and by 524,982 kg from 1,900,470 kg to 1,375,488 kg (L5 – L53A)
core and shear walls steel tonnage reduced from 106 kg/m3 to 86 kg/m3 (B2 – L5) and from 65 kg/m3 to 48 kg/m3 (L5 – L53A)
estimated material savings of RM 2,309,154
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.
