But generally speaking, the price is relatively low, and then make up after entering the market!
The nature of the price should be the contract price, that is, the price is determined on the basis of bidding competition when signing a contract, that is, the market-adjusted price.
The valuation basis should reflect the level of the enterprise, so the construction enterprise should compile its own enterprise quotation quota (and take it as enterprise secret) to bid. The quota shall be separated from quantity and price, which should reflect the technical level, equipment level, management level and labor efficiency of the enterprise in quantity, so as to make the direct consumption level of labor, materials and machinery teams of each sub-project scientific, advanced, competitive and standardized. Among them, normativeness means that the quotation quota of an enterprise is consistent with the project, measurement unit, calculation method and caliber in the Code for Valuation of Bill of Quantities of Construction Projects (GB50500-2003) stipulated by the state, and the quotation should be allocated to sub-projects, and the comprehensive unit price of sub-projects should be determined according to the market price information and cost index provided by the government or engineering cost agency.
2. Material cost
(1) Composition of material cost. Material cost refers to the material cost that constitutes an engineering entity and the amortization (or lease) cost of circulating materials consumed in the construction process. The material comprise that following component:
1) main materials. A characteristic of building products is that they need to consume a lot of materials, including building steel, cement, wood, glass, bricks, stones, sand, tiles, lime and so on. , a wide range. They are the most commonly used and used materials for building products, and they are also the main part of material cost.
2) components. Refers to the structural parts and accessories that constitute building products, mainly concrete structural parts, steel structural parts, wood products components and accessories, etc.
3) semi-finished products. Semi-finished products refer to ready-mixed concrete (commercial concrete) and ready-mixed mortar. In the production process of building products, semi-finished products are used more and more.
4) Auxiliary materials. Refers to the indispensable and widely used materials in building construction, such as lubricating oil, paint, adhesive, asphalt, etc. Although they do not constitute the main engineering entities.
5) Turnover materials. In addition to physical consumption, in the construction process of building projects, although some materials do not constitute entities, they are bound to be consumed in the production process of building products, and the consumption is very large and the cost is very high. It includes steel or wood formwork, supports, scaffolding, etc.
The composition of material cost shows that the material cost of construction engineering accounts for a large proportion in the cost of construction products, usually accounting for about 65% of the project cost.
(2) Calculation of material cost.
1) Material cost calculation formula:
Material cost = ∑ (fixed consumption of materials, components and semi-finished products × unit price of corresponding materials)
+∑ (Amortization amount of revolving materials × unit price of corresponding materials) (32-2)
Material consumption can refer to the consumption of the fixed subtitle, and can also be determined by the enterprise according to its own situation, but the engineering quantity must be calculated and determined according to the entity engineering quantity determined by the construction drawings. Amortization of turnover materials is a kind of consumption of construction means to ensure the realization of specific goals, which can reflect the competitiveness of different enterprises in market competition. Generally speaking, in order to win the project and reduce the bid price, the contractor should reduce the consumption of circulating materials, thus reflecting the competitiveness of the enterprise's construction technology and management level.
2) Composition of material unit price:
① The purchase price of materials refers to the market supply price of materials. All of them have included the supplier's handling fee, the loss from the place of origin to the supplier, the freight and the supplier's premium.
For materials that need to be packaged, the packaging cost should be calculated separately.
(2) Freight and miscellaneous expenses, including transportation expenses, and various miscellaneous expenses related to transportation, such as loading and unloading fees, barge fees, weighing fees, etc.
(3) Transportation loss refers to the loss of materials purchased from suppliers on the way to the on-site warehouse or designated stacking place.
(4) The purchase storage fee refers to the expenses incurred in organizing the procurement, supply and storage of materials. Such as the salary, labor insurance, travel expenses, transportation expenses, storage fees of materials warehouse, etc.
The calculation is as follows:
Unit price of materials = (material procurement fee+packaging fee+transportation and miscellaneous fees+transportation loss fee)
×( 1+ purchase warehousing rate)-packaging material recovery value (32-3)
The composition of material unit price is a summary of material price composition, and the specific material unit price should be agreed by the contractor and the employer in the form of contract according to different trading methods and supply channels.
