Quota set price tips?

The following is the related contents of the quota pricing tips brought by Zhong Da Consulting for your reference.

How to get the quota accurately?

1 What is line conversion?

Quota is the specified amount: it is to sum up a series of labor costs, material costs, machinery costs, management fees and profits to get a comprehensive unit price and evaluate the engineering quantity; The conversion is due to the price specified in the valuation table, or the labor and machinery do not meet their actual use, so it needs to be exchanged and re-priced.

Multiply by the corresponding proportion or coefficient, adjust the labor and rate, and regroup.

2 under what circumstances should quota conversion be carried out?

Principle of quota conversion: conversion is the process that the budget quota content of construction drawing is consistent with the construction drawing.

In essence, it is a process of adjusting the labor, materials and machinery of the original project according to the quota, so as to change the budget price of the project and make it conform to the actual situation.

Necessary conditions for conversion:

(1) It must be that the contents required by the design and construction drawings are inconsistent with or omitted from the contents of the quota project.

(2) The specifications of the materials and machinery listed in the quota project are inconsistent with the requirements of the construction drawing.

(3) The quota regulations allow conversion or the quota management department agrees to conversion.

What are the methods of quota conversion?

The methods of quota conversion mainly include:

(1) Classification by quota conversion position: manual conversion, material conversion, mechanical conversion and mixed conversion.

① Manual conversion: only the project quota is converted manually, and the others remain unchanged.

② Material conversion: when the quantity and price are affected by some (partial) differences in materials, specifications and quotas, the conversion shall be carried out according to the regulations, and the others shall remain unchanged.

③ Mechanical conversion: only a certain construction machinery fee is converted in the quota project, and the others remain unchanged.

(4) Mixed conversion: The construction drawing requires some changes to the work, materials and machines in the quota project, and two or more conversions to change another subtitle.

(2) Classification by calculation method:

① Addition and subtraction conversion method: that is, according to the quota regulations, reduce the consumption of labor, materials and machinery in the original quota project and increase the new consumption.

(2) Multiplier conversion: that is, the first coefficient in the labor, materials, machinery or budget price of the quota project is converted according to regulations.

General skills of quota pricing (taking frame structure as an example)

1 Earthwork: site leveling, excavation (manual, excavator), earthwork transportation (in situ, transportation), earthwork backfilling (excavation, transportation, backfilling).

Pile foundation: Take vibrating cast-in-place pile as an example: piling (pay attention to the empty part), embedding at the pile tip, reinforcing cage and drilling at the pile head.

2 Cushion: cushion, waterproof, foundation, structure: beam, plate, column (whether there is arc, slope, etc. ).

This part of the main structure should be fine.

Masonry project: what kind of brick, mortar type, one and a half bricks 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 stirrup), various component reinforcement, hanging reinforcement (at the junction of main beam and secondary beam), hole reinforcement, Rachel reinforcement when shear wall has end columns and wing columns, wall Rachel reinforcement (generally 600*600), horse stool reinforcement, column Rachel reinforcement, plate distribution reinforcement, negative panel.

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.

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.

Vertical transportation fee: generally calculated according to the construction area, and calculated manually according to the quota in some areas. This is easier to say.

There are two kinds of super-high fees: 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, the general installation hole area calculation, special calculation 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, whether it is flat inside or outside 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.

1 1 railings and handrails. Note that railings and handrails are generally calculated separately, generally calculated according to the extension meter, and the slope section * 1. 15. Note that the joint length 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 in ground engineering, ground painting is generally calculated according to the net area between load-bearing 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 is dripping, 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 periphery: 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.
