	If the building project also involves structural works, you need to obtain approval of the structural plans from the Building Engineering Division of Building and Construction Authority (BCA) before you can commence the structural works. Structural plans must be submitted by a Qualified Person who is a registered Professional Engineer in the civil or structural engineering discipline. You should submit your application for approval of the structural plans well in advance before you intend to commence construction works. It is an offence to carry out building works if the plans have not been approved and a permit to carry out building works has not been granted by the Commissioner of Building Control.
