During the joint review of drawings, the following problems shall be reviewed: (1) building part: whether the position of the plane layout of buildings (structures) on the general building drawing is unclear or insufficient, and whether the plane layout of buildings (structures) is inconsistent with the actual situation on site（ 2) First small then large: first look at the small sample drawing, then the large sample drawing, and check whether the detailed practices marked in the plan, elevation and section drawings are consistent with the practices of the large sample drawing; Whether there is any contradiction between the number, type and model of the adopted standard components and accessories atlas and the design drawings; Whether there is missing mark in the index symbol; Whether the detail drawing is complete（ 3) Building before structure: first look at the architectural drawing, then the structural drawing; Compare the architectural drawing with the structural drawing to check whether the axis size and elevation are consistent, whether there are contradictions, whether there are missing dimensions and whether there are unreasonable structures（ 4) First general and then special: the general parts and requirements shall be looked at first, and then the special parts and requirements.
At the same height of the podium roof and the standard floor, because the balcony elevation of the standard floor is generally set with a water drain reduced by 50mm, if it is also reduced here, it will be uneven with the podium roof.
