What are the sub-items that must be considered in the budget quota of civil engineering?

Take the frame structure as an example:

1. Earthwork: site leveling, excavation (manual, excavator), earthwork transportation (in situ, transportation), earthwork backfilling (excavation, transportation, backfilling). Pile foundation, taking vibrating cast-in-place pile as an example: piling (pay attention to the empty part), pile tip embedding, reinforcing cage and pile head drilling.

2. Cushion: Cushion and waterproof. Foundation and structure: beams, slabs and columns (whether there are arcs, slopes, etc.). ). This part of the main structure should be fine.

3. Masonry project: what kind of brick, mortar type, one brick and a half brick or more bricks. In some places, lighting fees are added to meet certain conditions in the basement. Note that some foundations are covered with brick membranes.

4. Concrete works: generally calculated by volume, stairs and balconies by projected area (straight lines and arcs). Some areas calculate the plate to the edge of the beam, and some areas calculate the beam to the plate. The pillar is the apex of the story. It should be noted that lintels, constructional columns (horse-tooth forks), window sills, decorative lines, balcony beams, coping and other small components, and the borders of stairs should be noted, which are basically calculated by square. Formwork: cushion, foundation, foundation beam, beam, plate, column, lintel, constructional column, small components, stairs, balcony, fence, etc.

5. Reinforcement: pile reinforcement cage (generally refer to the atlas, don't forget the calculation of fixed reinforcement and spiral stirrups), reinforcement of each component, hanging reinforcement (the connection part of the main beam and the secondary beam), reinforcement of the hole, Rachel reinforcement of the shear wall when there are end columns and wing columns, wall Rachel reinforcement (generally 600*600), horse stool reinforcement, column Rachel reinforcement, plate distribution reinforcement, etc. Prepare the staff recruitment budget

6. Roof: protective layer, leveling layer, waterproof layer, base layer and surface layer. Look at the detailed drawing and pay attention to the flooding and drainage: buckets, downpipes, grates, downpipes and elbows.

7. Scaffolding: Some places are calculated according to the external wall and internal wall respectively, while others are calculated according to the construction area. In some areas, there are single beams, columns, scaffolding, scaffolding and so on. When the storey height is more than 3.6m, full scaffolding should be calculated, and the ultra-high transportation fee should be paid attention to. Scaffolding should be calculated when the basement is not pumping water.

8. Vertical transportation fee: generally calculated according to the construction area, and calculated by fixed labor in some areas. This is easier to say.

9. Superelevation fare increase: There are two kinds: one is that the story height exceeds 3.6m (or 6m), and the other is that the eaves height exceeds a certain height. Just look at the calculation base clearly.

10. Door and window engineering: generally, the area of installation hole is calculated, and the special one is calculated according to the formula. Pay attention to whether the door is a wooden door, aluminum alloy, plastic steel or security door, a horizontal door or a sliding door, a rectangular door or an arc door, the thickness of the door frame, and whether the inner plane is flat or standing in the middle; Windows are the same as doors, but they are also divided into upward rotating windows, downward rotating windows, casement windows, sliding windows and fixed windows. Doors and windows should also pay attention to door and window plugs, hardware installation (generally excluding locks), wooden doors should be painted with varnish (according to design requirements), and windows should pay attention to the installation of windowsills, curtain boxes and guide rails. Prepare the staff recruitment budget

1 1. Handrails and handrails: Note that handrails and handrails are generally calculated separately, generally calculated according to the linear meter, and the slope section is * 1. 15. Note that the length of the joint is also calculated. If the railing is metal, it is generally necessary to brush the red lead antirust paint and the wooden handrail with polyurethane paint (according to the design requirements). The general quota will calculate these paints according to the quality (T), depending on what data you have. I usually calculate it according to 10 kg/m- 12 kg/m, and the metal handrail is generally 4.8kg/m. Please note that it needs to be multiplied by a factor, which is generally 1.7 1. Cast iron railings and fences depend on data. This is heavier.

12. Ground engineering: Ground painting is generally calculated according to the net area between main walls, without deducting wall ramming and column ramming, and without increasing the opening of doors and empty rings. The open area of the brick surface will increase. The bathroom is also waterproof, looking for slopes (average thickness) and so on. Stair wells usually include side faces and top faces. Pay attention to practice.

13. wall decoration: interior wall, painted cement mortar or mixed mortar, thickness, waterproof, thermal insulation, surface putty, latex paint or ceramic tile, ceramic tile specifications, adding side walls of doors and windows, and paying attention to dado; External wall: painting, heat preservation and surface coating (paint, granite, marble). In general, it is still necessary to hang a net and brush the interface agent at the junction of brick and concrete surface. Skirting board is generally calculated according to the extended meter, and the length of the hole is not deducted. Ceiling: paint, surface layer, ceiling, pay attention to whether there are gaps, the type of ceiling keel, and the folded part of the surface layer should be calculated. When painting, the beam side is generally included in the ceiling calculation.

14. Perimeter: steps, platforms, decorative sketches, painting of steps, surface course, handrails on both sides of steps, etc. , greening, open ditch (cover), manhole, septic tank, etc. There are standard practices, just set the quota directly.
