1. General procedures for joint review of drawings: the owner or supervisor speaks → the designer makes drawings disclosure → the representatives of the construction party and the supervisor ask questions → study one by one → form joint review records → take effect after signing and sealing.
2, must organize a preliminary review before the blue prints.the design. The problems found in reading pictures should be summarized, and a representative should make a main speech at the meeting. Others can make appropriate explanations and supplements according to the situation.
3. The construction unit and design unit shall assign special personnel to record the questions and answers raised for inspection.
4, the blue prints.the design record, signed and sealed by representatives of all parties.
5. Unit participating in the joint review of drawings: Article 5 of GB503 19-20 13.1.2: "Project supervisors shall be familiar with the engineering design documents and attend the joint review of drawings and design disclosure meeting hosted by the construction unit, and the minutes of the meeting shall be signed by the chief supervision engineer." This proves that the blue prints.the design and design disclosure should be presided over by the construction unit.
The main contents of the joint hearing:
1, whether it is unlicensed design or leapfrog design; Whether the drawings have been formally signed by the design unit. Whether it has passed the drawing review of relevant departments.
2. The geological exploration data is complete.
3. Whether the design drawings and descriptions are complete and whether there is a timetable for drawing in stages.
4. Whether the designed seismic intensity meets the local requirements.
5. Are there any contradictions between several design units and design drawings? Whether there is any contradiction between professional drawings and vertical section drawings; Mark if there are any omissions.
6. Whether the geometric dimensions, plane position and elevation of the general plan and the construction drawing are consistent.
7, fire prevention, fire control whether meet the requirements.
8. Whether there are errors and contradictions between the building structure and the professional drawings themselves; Whether the plane size and elevation of the structural drawing and the architectural drawing are consistent; Whether the representation methods of architectural drawings and structural drawings are clear; Whether it meets the drawing standards; Whether the embedded parts are clearly marked; Steel bar list; Whether the structural requirements of steel bars are clearly shown in the drawings.
9. Does the construction unit have any standard atlas listed in the construction drawing?
10, whether the material source is guaranteed and whether it can be replaced; Whether the requirements in the drawing can be met; Whether there are problems in the application of new materials and technologies.

12. Is there any contradiction between process pipes, electrical lines, equipment, transportation roads and buildings, is the layout reasonable and meets the design functional requirements?
13. Is construction safety and environmental sanitation guaranteed?
14, whether the drawings meet the requirements of the supervision outline.
Extended data:
Be familiar with the dimensions of construction projects, and then check whether there are any mistakes in the construction drawings. The main inspection contents are as follows:
1, check whether the slope direction of parapet concrete coping is inward.
2, check whether there is a beam under the brick wall.
3, beam on the structural plane, whether all the reinforcement in the beam table.
4. Check whether the height of the main beam is lower than that of the secondary beam.
5. Beams, slabs and columns are similar in the same span, but there are great differences in reinforcement. If there are any, they need to be re-inspected.
6. When the beam and shear wall are arranged on the same straight line, check whether the width of the beam exceeds the thickness of the wall.
7. When the beam is supported on the shear wall and column respectively, check whether the center line of the beam is parallel or coincident with the axis, and check whether the width of the beam extends out of the wall or column. If yes, it shall be submitted for design treatment.
8. Check whether the minimum spacing of reinforced beams meets the requirements of construction acceptance specifications. When ribbed threaded steel bars are used in this project, because the workers bend the steel bars when processing them, the diameter of the steel bars should be the original steel bar diameter plus the rib thickness of about 21mm.
9. Check whether there is an awning on the door of the indoor balcony, and check whether the center of the awning on the structural plane coincides with the center line of the door of the construction drawing. ?
10, when the design requirements and construction acceptance specifications are different. As often mentioned in the list, on the same section, the number of columns that can overlap on each side is less than 4 columns. However, the construction acceptance specification requires that the overlapping area of steel bars in the same section shall not exceed 50%.
1 1. Check whether there is any contradiction between the structural description and the structural plane, details, content and construction description in the beam-column table.
12, the single foundation system is stressed in both directions, and the reinforcement along the short side is generally placed on the reinforcement along the long side. Check whether the reinforcement in the foundation details of the construction drawing is wrongly drawn.
