How to differentiate the costing standard of construction and installation works? A class, two types, three types of projects is how to distinguish?

A, how to distinguish:

Categorized according to the standard classification of construction works to determine the classification, each province has this standard, different categories of fee rates are provided.

Taking fee refers to the process of obtaining measures fee, safety and civilization construction increase fee, enterprise management fee, fees, profits, taxes and other items in accordance with the provincial budget quota sub-total of each sub-procedure fixed base price, with reference to the fee standard multiplied by the relevant coefficients in turn.

Most of the civil construction quotas are based on direct engineering costs, while most of the installation works are based on labor costs.

For example: if a project civil engineering fixed direct cost of 100 yuan, multiplied by the safety and civilization of construction costs (assuming 1% coefficient), enterprise management fee (1.5%), fees (0.5%), profit (2%), that is, to get the increase in safety and civilization of construction costs, enterprise management fee, fees, profits were 1 yuan, 1.5 yuan, 0.5 yuan, 2 yuan. This process is the fee.

Two, distinguish between a class, two types, three types of projects:

Categorized by construction works, can be divided into the following four types of projects:

1, a class of projects

(1) span of 30m or more of single-story industrial buildings. Multi-story industrial plant with a building area of 9000m2 or more.

(2) single-furnace evaporation capacity of 10T/H or more or evaporation capacity of 30T/H or more boiler room.

(3) Multi-storey buildings with more than 30 storeys.

(4) Span 30m or more of steel mesh frame, suspension, thin shell roof building.

(5) Public **** building with a floor area of 12,000m2 or more, stadium with 20,000 seats or more.

(6) Chimneys over 100m in height. Water towers with a height of 60m or more or a volume of 100m3 or more. Pools with a volume of 4000m3 or more.

2, two types of projects

(1) span of 30m or less of single-story industrial buildings. Building area of 6000m2 or more multi-storey industrial buildings.

(2) single-furnace evaporation capacity of 6.5T/H or more or evaporation capacity of 20T/H or more boiler room.

(3) Multi-storey buildings with more than 16 storeys.

(4) Span of 30m or less steel mesh frame, suspension, thin shell roof building.

(5) Public **** building with a floor area of 8,000m2 or more, stadium with 20,000 seats or less.

(6) Chimneys with a height of 100m or less. Water towers with a height of 60m or less or a volume of 100m3 or less. Pools with a volume of 3,000m3 or more.

3, three types of projects

(1) span of 24m or less of single-story industrial buildings. Building area of 3000m2 or more multi-storey industrial plant.

(2) single-furnace evaporation capacity of more than 4T / H or evaporation capacity of more than 10T / H boiler room.

(3) Multi-storey buildings with more than 8 storeys.

(4) public **** building with a floor area of 5000m2 or more.

(5) Chimneys within 50m in height. Water tower with a height of 40m or less or a volume of 50m3 or less. Pools with a volume of 1500m3 or more.

(6) stacks, concrete storage silos, hoppers.

4, four types of projects

(1) span of 18 meters or less of single-story industrial buildings. Building area of 3000 square meters or less of multi-storey industrial buildings.

(2) single-furnace evaporation capacity of 4T / H or evaporation capacity of 10T / H within the boiler room.

(3) Multi-storey buildings with 8 floors or less.

(4) public **** building with a floor area of 5,000 square meters or less.

(5) Chimneys within 30 meters in height. Water tower within 25 meters in height. Pools with a volume of 1500 cubic meters or less.

(6) Sports grounds, concrete retaining walls, fences, baulks, brick and stone retaining walls.

Extended Information:

. p>Decorative engineering standards:

1, a class of projects

per square meter (decorative floor area) fixed direct costs (including unpriced material costs) more than 1600 yuan of decorative

decorative works; the external wall surface of all kinds of curtain wall, stone dry-hanging works.

2, two types of projects

per square meter (decorative floor area) fixed direct costs (including unpriced materials) more than 1,000 yuan

decorative works; external wall surface of the second block material surface layer of a single decorative works.

3, three types of projects

per square meter (decorative floor area) fixed direct costs (including unpriced materials) more than 500 yuan of decorative

decorative works.

4, four types of projects

independently contracted various types of individual decorative works, per square meter (decorative floor area) fixed direct costs (including unpriced

materials) of less than 500 yuan of decorative works; home decorative works.
