1. Can the parapet and gutter baffle on the exterior wall be counted as external scaffolding?
Answer: If there is a parapet on the exterior wall, the height of the external scaffold can be calculated to the top of the parapet. When the vertical height of the gutter baffle (from the bottom of the gutter plate to the top of the baffle) exceeds 50cm, the scaffold can be calculated as the parapet.
2. Can the railing protruding from the roof be counted as external scaffolding?
Answer: No.
3. If only the main structure (including roof insulation and waterproofing) is constructed, how to calculate the external scaffolding?
Answer: Calculate according to the regulations of the corresponding external scaffolding, and multiply the turnover materials in the quota sub-item by a coefficient of 0.7.
4. How to calculate the external scaffolding of the building’s additional floor?
Answer: The external scaffolding of the building’s additional floor is calculated by multiplying the height from the outdoor floor to the top of the exterior wall masonry by the outer perimeter of the exterior wall. Apply the corresponding external foot scaffolding quota sub-item multiplied by a coefficient of 0.5.
5. The building is wide at the bottom and narrow at the top. The upper external scaffolding is set up on the lower roof. What height is the quota for the upper external scaffolding?
Answer: The quota for the upper external scaffolding is based on the height from the lower roof to the upper eaves drip.
6. When calculating the scaffolding for the inner wall, is the height occupied by the ring beam deducted?
Answer: The height of the ring beam is not deducted.
7. Can the scaffolding be calculated for the frame beams and continuous beams that are integral to the slab?
Answer: The scaffolding cannot be calculated for beams and slabs with beams and slabs.
8. How to calculate the scaffolding for the footsteps of the frame column?
Answer: The scaffolding for the inner columns of the cast-in-place reinforced concrete frame is calculated according to the regulations for independent columns. The scaffolding is not calculated for the frame side columns around the building.
9. How to calculate the scaffolding for the reinforced concrete short-leg shear wall?
Answer: The scaffolding for the reinforced concrete short-leg shear wall is calculated according to the regulations for the scaffolding for reinforced concrete walls.
10. Can the scaffolding be calculated for the elevator shaft wall?
Answer: The elevator shaft is calculated by the elevator shaft hole, and the construction of the elevator shaft wall cannot be calculated for scaffolding.
11. When calculating the full-floor scaffolding during foundation construction, the quota stipulates that it is calculated according to the bottom plate area. What does “bottom plate” refer to? Is there any regulation on the depth?
Answer: “Bottom plate” refers to the bottom plate of the foundation, not the cushion layer. The depth should be greater than 1.2m.
12. The cantilever scaffolding only has a sub-item of steel pipes. If it is built with bamboo, how to apply the quota?
Answer: Apply the sub-item of steel pipe cantilever scaffolding, and do not convert it.
13. How to calculate the scaffolding of the cantilevered corridor?
Answer: When the cantilevered corridor protrudes from the exterior wall by more than 1.2m, the cantilever scaffolding can be calculated according to the length in the direction of the wall.
14. Can the scaffolding be calculated for the balcony partition wall?
Answer: Yes, it can be calculated according to the regulations for the corresponding wall scaffolding.
15. If the general contractor subcontracts the exterior decoration, can the decorative scaffolding be calculated?
Answer: No, the external scaffolding is not multiplied by the coefficient.
16. If the ceiling keel construction height is above 3.6m, and the ceiling surface height is within 3.6m, can the full-floor scaffolding be calculated?
Answer: The full-floor scaffolding can be calculated based on the construction height.
17. This chapter explains that Article 3 “the external scaffolding above 24m also includes the materials and labor of the ramp”, so can the external scaffolding above 24m be calculated separately for the ramp cost?
Answer: It has been considered and will not be calculated separately.
18. If the septic tank wall depth exceeds 1.2m, can the scaffolding be calculated?
Answer: Yes.
19. If the septic tank bottom plate area exceeds 20m², can the full-floor scaffolding be calculated? If the full-floor scaffolding is calculated, can the masonry scaffolding still be calculated?
Answer: The full-floor scaffolding can be calculated if the septic tank depth exceeds 1.2m and the bottom area exceeds 20m². The internal scaffolding is calculated separately when the wall is built.
20. What is the basis for calculating the engineering quantity of safety nets and vertical enclosures of buildings?
Answer: Calculated according to safety regulations and approved construction organization design.
21. Where is the overhead transport road used?
Answer: When two adjacent buildings are under construction at the same time, a passage is set up on the floor to facilitate the movement of people and materials between the two buildings.
22. How to calculate the scaffolding used for installing components?
Answer: The scaffolding used for installing components has been comprehensively considered in the component installation quota and will not be calculated separately.
