▓ Quantities overview

Fixed pricing system: is the product of the planned times, in a specific historical context to determine and measure the standards of construction and installation cost, standardized the construction market, the price has been established by virtue of certainty.

Quantities: refers to the owner or owners delegate has qualified intermediary, by engineering calculation rules and uniform classification of construction projects, according to design drawings and construction site to the actual situation as the tenderer provide real engineering project and technical measures the number of items; the tenderer in accordance with the requirements of bidding documents, the number of construction projects, in accordance with the level of the enterprises of construction, technical and mechanical equipment, management level, price information to grasp the situation and take full account of the various risk factors, on the tender documents in the quote list.

Quantities of nature: mandatory, practical and competitive.

Project list mode item prices constitute

First, the quantity of Fund

The project's expenses include sub-project engineering fees, charges, and other measures to project the project costs, fees and taxes.

1. the minutes portion of the project fee: means the complete project list lists the distribution breakdown of quantities. Generally include artificial fee, material fee, construction machinery fees, management fees, profits and risk costs. Including artificial fee, material fee, toll was constitute construction machinery distribution sub-item project fee of the main cost is in construction direct cost of project entities and contribute to the project entity formation fees.

2. measures of project expenses: in addition to the quantities in the cost of the project, in order to ensure the smooth progress of the project, according to State existing construction projects construction and acceptance of, procedures required, must match the content of the project is completed. The entity measures and supporting measures fees.

3. other project costs: $ gold, material purchase costs, General Contracting services, ad-hoc project costs estimates the amount of the sum.

4. fees: the Government and relevant departments required to pay the costs. As works of sewage charges, fixed determination of costs and unemployment insurance.

5. taxes: according to the national tax rules of construction and installation the project to be included in the cost of the business tax, city maintenance tax and education expenses surtax.

Second, the cost calculation

1. the minutes portion of the project fee

Includes complete all parts of the project of the artificial fee, material fee, construction machinery fees, management fees, profits and risk costs.

A. personnel cost calculation: directly engaged in the construction and installation the project construction of production workers spending of fees, not including managers, support staff, and other expenses.

Labour cost = Σ (artificial shadow days price × artificial shadow days consumption)

B. material fee: refers to the construction of the composition of consumption during the project entities to various types of raw materials, spare parts and finished products and semi-finished products, and other major material costs and project costs while not constitute works of entities, but help engineering entities formed by the various costs of expendable materials. There are main materials and consumables.

Material fees = Σ (material price × material consumption)

Material price determination involved are: material price, packaging, purchase maintenance costs, transportation costs, materials testing laboratory fee and other fees (customs, port charges, insurance premiums), etc.

Determination of material consumption should note the following aspects:

1) quantities calculation rules, list of works by net metering, therefore the amount of the cost of materials in addition to the calculation of the quantities of material outside of the net amount should also consider the amount of the loss of material.

2) quantities, already provide part of the main materials, this part of the material should be the net amount and the amount of the loss and for pricing. For a list of the main materials are not available, the calculation of the cost of materials cannot be ignored, should be based on project needs and the other material consumption indicators.

3) it should be noted that distinguish the main materials, consumable materials, working materials, low value difference, its consumable materials fee calculation.

C. construction machinery toll calculation: refers to the use of construction machinery operations occur in mechanical royalties and machinery, demolition and

Access fee. Do not package management staffing of car and vehicle used to access tasks.

Construction mechanical royalties = Σ (mechanical comprehensive price of rent price × machinery rent consumption) + construction machinery and farm and dismounting fee

D. fee calculation: Organization construction of production and management. Formula: a formula method and prediction method.

1) formula calculation method:

Management fees, management fees calculation base × = rates

Note: the formula of calculation base for direct costs or labor, or for labor and machinery costs aggregates, depending on the circumstances. When you install works bear management fees to labor for the Cardinal, civil works bear management fees to direct costs to the base.

2) prediction method:

E. profit calculation:

F. risk fee calculations. Formula: a formula method and prediction method.

Risk costs = cost of project risk rates *

2. measures of project costs

3. other items fee

4. fees: the fees = calculation base × fee rates

5. taxes: tax = (cost + profits before tax) × tax rate
