Whether the choice of the construction project ofthe frame bridge is right or not, directly exert an influence on whether frame bridge can take seat, and relateto the engineering price and engineering progress.
The prediction model GM(1,N) of engineering price index in Heilongjiang province according to taking total index of engineering price as characteristic set of surface features system, taking artificial cost, lumber, cement, local material, mechanical used cost as correlation factor set. The grade of simulation precision belong to first class by means of examining forecast of model, it can accurately forecast engineering price index.
Based on the characteristics and connotation of forest ecosystem services,the physical and value assessment methods,including market value method,shadow engineering price method,production cost method, opportunity cost method and administering expenditure method,were used to evaluate forest ecosystem services in Yashushan Natural Reserve.
Referring to the many drawbacks of conventional engineering cost management, this paper brings forward the concepts, from the micro and macro aspects, of engineering price management reform and presents the rationale for the establishment of quoted price decision - making system so as to set up as quickly as possible the engineering cost management system, which will be macro directed by the government and allow the enterprises to make the quoted pjice independently with the price formed through market competition.
Nowadays, China's engineering price management is experiencing profound changes from planned economy to market economy, and the focus is the reformation of construction price foundation and price pattern.
Third, because the engineering price system changed gradually from quote to the detailed price list, and the work period of the construction engineering is widespread and longer, the risk of the price changing of the engineering should be undertaken by construction business enterprise, it is already an urgent matter of the moment to establish internal control system in construction business enterprise.
From point of view of engineering quantity list price , the paper explains all sectors of construction market how to do engineering price computation under the price computation pattern of engineering quantity list.
According to rent theory, externality theory of economics, this paper analyzes mechanism of water price forming, puts forward that water price should involve resources price, engineering price and environment price, and the re-decided water price is in distinctive comparison with existing water price which is basically engineering price.
On the basis of clear water resources value connotation and price composition, this paper analyzes ways of natural resources' price forming and states forming idea and forming principle of water price model. Analyzing relative factors of water pricing, this paper puts forward structure of water resources pricing model, makes pricing model of resources price, engineering price and environment price respectively, and sets up dynamic all-cost pricing model.
In the light of a case study and based on the prices of the products manufactured by some main fire product manufacturers in China, the comparison was done among the products, the installation of the materials as well as the prices of the products according to the base price quota for the equipment installation budget and the engineering price ratio of the three gas fire extinguishing systems under different fire extinguishing patterns has been fixed.
Compensated emitter is the most ideal emitter among micro-irrigation equipment. The emitter not only keeps a consistent discharge and improves water quality, but also slows down the blocking, does self-clcanina and cuts down engineering price. The success of developing domestic compensated emitter has filled the gap in the field in China and has paved the way for further developing compensated emitter.
The engineering price parameters in metallurgical mine construction is calculated,which is universally applicable of many kinds,according to a computer program of relevant cost quota.It is favourable to work out high-speedly the budget(budgetary estimate) and marked price.
This paper has discussed the structure and method of implement of the price catalogue software for photovoltaic water pumping system under windows3. 1 environment.In the method,Object Oriented Programming technique, Microsoft C++ and Microsoft Foundation Class (MFC) have been used to make the software reliable.The using of MFC also makes the complex Windows Programming user interface much easier. The method is also applied to other engineering price catalogue problem.
