The implementation process of the construction project is the transformation of the design drawings to the construction entity, but also the process of human and financial resources. Because the construction period is generally very long, during the period of the workers wages, the consumption of a variety of building materials, the purchase of materials and equipment, and market supply and demand changes in the construction process plays a vital role. At this time, we must make reasonable use and control of the project cost, to ensure that the budget expenditure is based on the efficient completion of the construction, guarantee the entire cost of reasonable and effective.
1, the impact of the construction cost of the accuracy of the factors
1.1, design leakage and change
The design of the project is very common in the design of the design of the project and the change is very common, and these additional items will be reflected in the total cost. This situation is usually caused by the following aspects: first, because of the lack of clarity on the relevant national design standards, and the design of the program is not enough to lead to a sound, and secondly, the design work is not enough to cause. Design units due to lax supervision, design tools and standards have not reached the national standards, so that in the specific project construction, the means to increase investment to carry out the contents of the adjustment and change.
1.2, the extension of the time limit for a project
Construction period is one of the main control targets in the construction project implementation phase. If there is a delay in the construction period, the benefit of the whole project will fall, but also will increase the additional cost of the loan interest, which will make the cost of the project beyond the scope of the budget.
1.3, environment, market and other factors.
The construction project is very large, and the time limit for a project is very long, which makes the whole process of the whole project is influenced by the market price, the market supply and demand. Although the project will do it in the early adequate budget, but can not the market made to figure out the full budget, which makes in construction process will still be beyond the budget range.
1.4, construction equipment material price error
At present, China's domestic production of the same products are very many, but the standard is not uniform, the price is also uneven, which makes the difference between the price of the same kind of construction equipment is very obvious.
1.5, the management level of the budget
The budget establishment personnel can not carry on the detailed estimate to the entire project implementation process and the cost budget situation, this makes the thing which the budget is out of the ordinary, also cannot make the concrete appraisal. Cost budget will be due to the blind and the lack of consideration in the actual construction process to play the utility and is not big, and the behavior of the super budget often occur, which is to ensure the smooth implementation of the project and the quality of the clearance.
2, construction project implementation phase of the project cost control measures
Project cost management in the implementation of the entire process of the project. So it is not right to pay attention to the pre budget and the settlement of the project. In other words, in the construction process, must be on the construction site, engineering change management, in order to avoid the waste of resources.
2.1, do a good job in the construction contract signed
Construction contract is the main constraint of the project construction, and it has important meaning and function to the restriction of investment and construction units, the power and obligation of the parties, and to regulate the construction of the contractor. Is also the investment side and the construction unit to control the progress of the project, effective measures and means of effective supervision of the quality of the project. When the contract is signed, it can be carried out in accordance with the provisions of the terms of the responsibility and the right to implement, in particular, the contract in terms of default, schedule planning and project progress, clearing the way, etc.. When the contract is signed, the contract is not clear enough to reach an agreement through conciliation and negotiation.
2.2, construction organization design optimization
For the construction organization design, its content covers a number of aspects, including not only the construction scheme and methods, but also including the construction progress of the target and various security measures, etc.. In order to achieve the best construction quality, we must strike the most reasonable construction scheme, and to judge whether a construction scheme is reasonable, we must take full account of its economic factors. For the supervision unit or construction unit, they should carefully examine each content, especially from technical and economic point of view to analyze and evaluate the construction scheme, the construction scheme is not only reasonable, but also should be as low as possible, so that we can achieve the purpose of improving the construction efficiency.
For example, the municipal pipe network of a construction project, in the construction plan, determine the artificial excavation in this way, but the site after the discovery can be used in mechanical excavation method, at this time the corresponding part of the construction plan should be adjusted in time, so that can reach the purpose of saving costs.
2.3, strengthen the construction budget review
For the project settlement, it is a key basis for the construction budget, which is also the key to the construction stage of the cost effective. From the actual situation of the project, the construction unit in order to achieve the purpose of personal purpose and deliberately to improve the amount of work, and the construction unit deliberately repeated calculation. For the project cost management, must read through each construction drawings, but also to the charging standards and the existing quota have a full understanding, so that they are in the process of auditing the project budget will be able to eliminate the problems of the engineering budget, so that the actual project cost can be truly demonstrated through the budget.
2.4, strict engineering materials, equipment prices
To build a set of perfect system of inquiry, not only contains the material inquiry, but also contains the equipment inquiry. For any construction project, the cost of material in its cost structure will usually reach more than 60%, so the cost of control materials becomes a more important part, it will directly determine the cost of engineering construction can be effectively controlled. Under the environment of market economy, there are a variety of material supply channels, so for project cost management personnel to pay close attention to the materials market, for price fluctuations of material should be well aware, for materials for the future price changes have a certain pre judgement ability, so that you can make evaluation on pricing for the Party of the first part of the, or request Party A to replace the low price of the material, or request Party A to set the price of materials. Through these measures, to a certain extent, the cost of the project can be guaranteed.
2.5, to strengthen the construction unit site management personnel, technical personnel management
To continuously improve the construction of technical personnel and management personnel of the personal qualities, to instill their practical ideas, making them in the work process should try to comply with the facts, in accordance with the provisions and requirements to implement. At the same time, but also let them see the key and the importance of saving investment, and ultimately achieve a win-win situation both a and B.
2.6, to strengthen the engineering change, on-site visa and claims management
In the construction process, because of the actual situation and the ideal situation there are some differences, which lead to the actual process of the planning and the existence of a certain deviation, which requires the construction of the construction process to adjust, or adjust the project quantity, or to adjust the construction project, which requires them not only have higher professional quality, but also requires them to have a strong sense of responsibility, only in order to make the best response. On the other hand, to effectively control the project cost, but also from the contract management, which requires management to fully understand the relevant terms of the contract.
3, concluding remarks
With the rapid development of the construction industry in our country, the most important point is to start from the implementation stage for the construction project. This paper analyzes and studies the problem of cost control in the stage of implementation. The factors that affect the cost control of the implementation stage are obtained, and some countermeasures are also put forward, which can greatly improve the investment benefit of the construction project, which has a certain theoretical and practical significance.
