On the construction project cost control and management

[Abstract] project cost construction of a large content, which is due to cost control, efficiency will directly impact the construction of the economic benefits. Engineering units should be prepared to cost control, cost of Investment in all aspects of strict control, this is the ultimate task of the modern project management in order to guarantee the construction cost at a reasonable range, the need to continuously improve the project management of production process Technology and economic management for these, this paper focuses on analysis of construction cost control related issues .

[Keywords] construction, cost control, management

Market economic system changes making the construction Industry as an Investment hot spot, which has a role in promoting the construction cost. A direct impact on project cost management of construction Investment in the economic interests of the whole market and economic development unit has a role in promoting self-employed from the actual situation , China's construction cost management of lower quality, higher capital Investment cost of the project, project cost management system also need to face more issues that hinder the sustainable development of the construction Industry.

1 to reduce the significance of construction cost
Project cost involves multiple aspects, such as: construction and installation costs, equipment, apparatus purchase costs, other expenses and so on. Construction project cost management is the focus of the daily management of Engineering units, a direct impact on construction projects to create economic value from the perspective of Engineering units, only the production process for project management and implementation of technical economic management, in order to achieve the desired effect of the construction.

Construction cost management efficiency level of Investment for the entire project has a great impact, not only affects the economic return on Investment, but also on the Engineering units of the survival and development. Because of large-scale construction projects, long construction period, high technical difficulty, resources consume more, to show the full economic value, we must ensure the accuracy of Investment if the cost of policy failures Engineering units, will result in economic losses in many areas. Thus, in order to achieve reasonable control of project cost must be in all construction stage multiple pricing, refer to the operation of process control and reasonable cost.

2 Construction cost management principles to be adhered to
2.1 and harmonious relations, quality control
Here's "relationship" refers to the project cost and construction quality of the relationship of project cost is the end of a project requires major Investment in labor, machinery, materials, comprehensive costs, according to the investor, designer, construction, contractors, auditors and other units of nature, need to invest in construction cost are not the same, such as: Investment estimation, design estimates, construction drawing budget, contract price, settlement price, completion of settlement, etc. project quality is mainly completed, the building use performance standards to be consistent and drawings, the technical parameters should meet the standard drawings. taking into account the project cost and the link between the quality of the project, but also to follow the project life-cycle project cost and quality of the project with changes, We are more stringent project cost controls. Note that Investment in construction projects can not only focus on reducing costs and saving money for the project must be fully expense the cost of inputs, this would avoid the cost and cost of the project was missing, leading to Construction work is difficult to proceed smoothly.

2.2 new concepts to optimize the management
Value engineering can be seen as value analysis, these buildings for improved internal quality of great significance. The function of the construction analysis and evaluation of the implementation, reducing the cost of the project in many ways, this is the pursuit of each project unit in the building design aspects, the functional requirements of the project and investment combined with each other, according to the specific requirements of construction, by means of effective measures to reduce the cost of inputs, each construction unit is to actively think about. engineering aspects of the value in active use Engineering is an effective combination of technical and economic model In addition, the use of value management rapid progress in the construction Industry, which gave the project management to create the conditions usually, use the value of the entire construction project management can reduce The initial investment of 5% to 10%, and reduce project operating costs of 5% to 10%.

3 stages of construction cost control and management measures
3.1 Decision stage of cost control and management
Investment decisions during the biggest task is to undertake a comprehensive project feasibility analysis to determine whether the options put to practical work. Engineering in the period when the project cost management tasks must be completed, including identification of program, preparation of plans, estimates and other investment Investment in the project estimate has a significant role in the project, it is the project decision-making, design, construction, completion of accounts, etc. part of the main basis of the total investment projects have a decisive role. Both units during the decision-making according to their point of view, and factors associated with the complex needs of the development of a line, then according to programs of a reasonable valuation, while the accuracy of estimates of investment will be related to the effectiveness of project implementation. This required engineering units can be based on the actual situation, arrange a high level of unit investment estimation process.

3.2 Design phase cost control and management
Design work is the construction of the soul, for processing and economic relations between the operational aspects of guiding significance for project cost control effect is particularly significant. Engineering solutions to optimize a direct impact on construction projects, one-time investment size, and the completion of delivery after the economic benefits of the project will create an effect. review the design units in the development of programs, the construction unit must do to optimize the design work from the construction of long-term situation, the project implementation plan before improvements can be optimized to reduce the amount of the cost of accounted for 75% of these are to remind the engineering units in order to fundamentally reduce the project cost, you need to focus on pre-program optimization work. the use of different optimization measures to promote the construction process of simplification, to avoid material , equipment, waste of resources, in many ways to achieve financial savings. design-time cost control measures include: (1) ceiling design of a project construction plan design, funding will be rated as the design basis, the design process to fully adhere to the principles of the design limit, the amount of decomposition of investment and engineering in the design process in carrying out the limit is a common way to its main stage to the design and construction validation of the investment amount of the first decomposed into different industries, then break it down into various units of work and the division of engineering, so that layers can be allocated down from the grasp of all aspects of the use of funds, the design specifications, design standards, project number, budget indicators strict control (2) change management in construction projects often encounter this situation, after a good project design needs to make adjustments or modifications, which will bring the project cost for the direct impact of the project management adjustments to be as early as possible, if the construction plan will be adjusted have a big impact.

3.3 phase of the bidding cost control and management
Engineering units in the preparation of tender documents must be integrated more than one point of view, let Daijiandanwei, tender side of the project cost control more convenient. Need to design content to relax, all use of the funds must be identified through a professional auditor for project contractors, in addition to considering their construction techniques, but also need to focus on study contract given its price. In addition, we need to adjust the list price for the relevant provisions in the BOQ quantities error, resulting in project engineering change the amount specified in the contract with the errors, you need to add the appropriate funding, while the fees, taxes and other timely change. This is to ensure the stability of the project cost, in order to avoid too large changes affect the cost management construction signed a contract unit is particularly important, need to focus on the content defined in the contract. with the actual situation of the construction market, construction of the project cost of materials used to strictly control and avoid the high cost of factors caused the problem. Example: Material price changes is too large to be scientific adjustment, the magnitude of the cost of change in the effective control range.

3.4.1 Strengthen the construction and site management:
Construction units and the construction side to do the construction site of the transfer of management, reducing unnecessary losses, such as the construction of an office building, due to poor management of the construction unit, have other sites caused by the construction site for dumping construction waste 18000 m3, the garbage The collection, transport and disposal costs up to 28 million. To improve site management, site earthwork balance control, arrangements for the construction process, especially outside of the construction of various district to make reasonable arrangements in order to avoid unnecessary waste.

3.4.2 improve the engineering change management:
Engineering change projects carried out mainly for the change after the adjustment, the different designs in the impact after the change are not the same, while the project is the result of a direct impact on project costs, in particular, most of the change project price and bidding price competition there is a big gap between the final price need be negotiated engineering units, and thus to control the total project cost of the larger obstacles in the change management process, the need to give attention to the visa Information . When it comes to data changes must go through the Party representatives, representatives of the construction and supervision units three signed, sealed, so the contract agreement to be effective. And if they consider the cost of cost, not all of the engineering change can calculate the contract price, If this process does not have enough Information, formalities, it is difficult to get a good price.

For the project after the visa part of China's legislature is issued in the early documents related to give clearly defined. Example: the Ministry of Construction, the State Industry and Commerce issued the preparation of the "Construction Contract model text>> that the file clearly provides: When the engineers at the exact time could not give a written confirmation, the contractor engineers need to be given verbal instructions in writing within 7 d after the manner of identification, engineers made sure the contractor after 48 h if not to reply, is seen as the default instruction. If an exception occurred during the construction accident problem, as once a visa is required, issue a visa and, as Daijiandanwei visa management system in the field need to strengthen the management requirements for all visa requirements to meet the standards may not appear unauthorized visa phenomenon.

3.5 completion of final closure of cost control and management
Completion of the settlement will be engineering units often overlooked, this part is to ensure cost control costs. For settlement according to the design drawings and projects should be strictly contract operations, must produce a single final acceptance, for example: when a change in the acceptance of single-pointed, settlement amount will have to be removed. carry out a comprehensive project budget to negotiate changes in visa and work accounts, check for detailed engineering materials price control of the audit and when the original tender document control, where projects not included within the original base price of secondary settlement. completion of the settlement agreement must comply with the contract and the contents of the proper allocation of awards ahead of schedule, quality awards and other expenses, the project involves a system for full compliance.

4 Conclusion
All in all, construction cost management is an integral part of construction projects, the construction process to do many aspects of construction preparation, control of the entire cost of investment in the effective range, in order to achieve the project create greater economic benefits. Construction unit to be active with science and Technology principles and economic and legal means to handle the engineering work at various tasks for different periods of construction, to fully take control of cost effective strategies, according to market trends to develop the economic cost management solutions, and ultimately maximize economic benefits.
