Cost estimate for a 40 storey building
• Constructing a 40-storey building demand for considerable financial uncertainty.
• To minimise such financial risks it is important to accurately estimate the schematic construction
cost.
• For effective cost estimation schematic costs estimation model (SCEM) is applied.
• SCMD involves a number of practices such as floor plan, elevation views of the exterior, site plan,
roof plan and building section.
