Design Considerations  as per Malaysia Local Code and equivalent of Chinese standard    
Design Loads and Safety Factors 
   
""The loads considered are as follows:
·        
Dead Load (self-weight of the building structural components)
·        
Live Load
·         Earth quake load.""  
  
The design method is Limit state design and the load factors considered on the basis of the Malaysia Building Code Standards and equivalent of Chinese standard are as follows:

         1.2 for dead load(Modified)
          1.4 for live load(Modified)
   
The partial safety factors used in the design are:

1.5 for concrete        
1.15 for steel
    
3.0 for derivation of the allowable bearing capacity for the foundation design.
     
2. Basement & Basement roof slab(if any) shall be in RC Concrete.

3.Staircase&Lift shaft will be in steel structure.
