(1) Metallic materialsMetal materials are the most important engineering materials, including metals and metal based alloys.Metals and their alloys are divided into two major parts in industry:(1) Ferrous materials - iron and iron based alloys (steel, cast iron and ferroalloys).(2) Non ferrous materials - all metals and their alloys except ferrous metals.Nonferrous metals can be divided into light metals, fusible metals, refractory metals, precious metals, rare earth metals and alkaline earth metals according to their properties and characteristics.

In accordance with national regulations;The capital construction project budget is carried out in stages along with the construction procedure.Due to the different budget system basis and work depth at each stage, the budget of capital construction projects can be divided into two categories: first, budget estimates;The second is budget.The budget estimate includes the investment estimate of feasibility study and the budget estimate of preliminary design. The budget can be divided into the construction drawing design budget and the construction budget. The capital construction project budget is the general name of the above estimates, budget estimates and budgets.
1. Investment usually refers to the economic activities of purchasing and constructing fixed assets and purchasing and reserving current assets.twoThe investment used to purchase and construct fixed assets is called fixed asset investment.Such as buildings, structures, machinery and equipment, transportation tools, etc.threeThe investment used for current assets is called current asset investment.For example, raw materials, semi-finished products, cash on hand, bank deposits, etc.fourAccording to the degree of centralization of investment decision-making, investment can be divided into highly centralized, decentralized and comprehensive investment system models.fiveInvestment regulation mainly guides and adjusts investment direction through finance, taxation, loan interest rate and financing means.
Prohibited acts.It is prohibited to contract construction projects in parts.The contracting unit of a construction project may contract out the survey, design, construction and equipment procurement of the construction project to one general contractor.However, it is not allowed to divide a construction project that should be completed by one contractor into several parts and contract them out to several contractors

Main factors affecting project cost in project design stage1) General layout design;2) Process design;3) Auxiliary facilities, public facilities and construction standards.
This information is the basic knowledge of project cost and cost accounting, ppt format, 28 pages.This courseware introduces that target cost is the difference between expected revenue and target profit. For enterprises, the target profit rate should reach the level of similar enterprises so as not to fall behind.For engineering projects, only when the target profit reaches the level required by the Engineering Bureau, can the enterprise's goal be achieved.Target cost management emphasizes that we should take action rather than remedy problems when they occur.
(1) Meaning of project cost information All data that play a role in the determination and control process of project cost can be called project cost information.(2) The beautiful editors who manage the project cost information can best reflect the characteristics of the change of the project cost information, and the project cost information that plays an important role in the market mechanism of the project price mainly includes the following categories: 1) labor price;2) Price of materials and equipment;3) Machine shift price 4) comprehensive unit price;5) Others.2、 Project cost data (I) Classification source of project cost data: 1. Different project types: divided according to their different project types (such as factory buildings, railways, residential buildings, public buildings, municipal works, etc.), and listed their individual projects and unit projects respectively.2. Different stages: according to their different stages, they are generally divided into project feasibility study, investment estimation, preliminary design budget estimate, construction drawing budget, completion settlement, project final account, etc.3. Different scope: construction project, single project and unit project cost data,
