Engineering bidding work often facing cost exceeds the problem, how to effectively control the cost become the focus of research. This paper analyzes the engineering bidding on the significance of the work cost control system, discusses the cost control of the existence of the main problems, and puts forward some improvement, countermeasures for the future of the tender to provide help.
Control the cost of scale is engineering bidding work one of the important targets, but the cost is related to many factors, and throughout the project always, budget over budget and final accounts more than the budget occur frequently. So in the bidding work of the implementation of scientific management, and to increase the cost control of the initiative is necessary.
A, engineering bidding work the importance of cost control.
The bidding work for engineering in recognition of the importance of cost control, should make clear above all the connotation of cost control. “Control” the basic connotation of the project budget and final accounts is to prevent the too high, and serious than expected. But “control” has its relativity, too high and low cost is not reasonable. The higher cost of increased the pressure of the enterprise, and there are also not reasonable pricing. Similarly, low cost, were likely involved in construction quality, because the cost control is not only related to investment funds, and the future project quality closely linked. The project construction cost is raw materials, artificial, construction technology and so on various factors of result, made of high quality raw materials, hire a professional construction personnel, and adopt scientific and reasonable design, the overall quality of engineering can have positive effects. Therefore, the cost control also should prevent not reasonable low cost budget appear, the importance of the work is that how to set out the optimal cost input. Especially in the bidding work, through the design scheme, the paper analyses the reasonable cost budget, the actual cost of the future construction will try to keep within the budget, the whole project also will more smoothly.
Second, the bidding work of engineering cost control problems.
First, the raw material price change risk to cost control impact. Raw materials in all kinds of project construction cost is the main form factors, relative labor costs, the change of raw material price change risk loss caused even more serious. For example, the 2008 financial crisis raw material prices fluctuate; Begin in early 2011, the trend of rising prices of raw materials and is very significant. When the tender price is determined, the late once the rising prices of raw materials, the project will be forced into a passive in. The tender period relatively low price and can’t avoid the happening of the late price risk, price low expectations become a major problem. In the bidding work, make the tender inviting party design scheme, would have the tendency of lower prices, hope to find the bid price lower contractor, this is the cost control of security, but also can lead to changes in prices for the future of the tender inviting party insufficient attention.
Second, the construction of the influence of cost control visa. In the tender period, each bidding unit in accordance with project called for the construction scheme will also have a difference. Some bidding unit in design will increase construction link, and cost budget will be improved. Some unit cost budget is not high, in construction process can produce visa problems, and make the anticipated cost increase. Although construction with the tender belong to different link, but the bidding phase of the cost control of construction has the effect of visa recessive, tender inviting party for basic comply with the design requirements of the unit, largely from the point of view of cost price implementation of screening, the cost of probability increase later appear be higher. The tender inviting party faces bidders construction experience and technology are different, some bidders can discover in time design plan in the construction of the lack of link, which in the late stage of the bid to construction technology to improve it, this is to avoid the important measure of cost changes.
Therefore, in the bidding work of the cost control of more wide range should implement, in order to reduce the occurrence of of all kinds of risk.
Third, construction and supervision of the cost control with influence. In the bidding phase, the tender inviting party required to choose supervision unit responsible for future construction supervision, the choice of different ways. Some units are based on long-term cooperation, some units are based on the specific engineering, some units are based on supervision brand. No matter choose which kind of way to establish supervision unit, supervision work there are difficult, for example, the construction units will try to reduce the quality of the bit, directly on the supervising units; The subcontract, sub-contract in raw materials, construction technology, quality problems, supervision found that the problem is difficult to solve the system. Construction and supervision in with the problems on the cost will have direct impact, but these problems in the bidding phase can from the point of view of the contract for the corresponding hedging and this is often ignored in the tender inviting party.
Three, project bidding for cost control measures.
First, strengthen the expected cost analysis. Raw material price change and economic operation of the whole is closely linked, the analysis of the use of science, can for a period of time in future trend of raw materials to make expectations. The bid invitation unit tender in screening are gambling process, actually is a choice of the unit price low, still choose to offer slightly tall, but the unit more persuasive is short-term interests and long-term interests of the game. Therefore, combined with engineering construction period cost analysis in expected is very important. The bid invitation unit should be in comprehensive analysis of international and domestic raw materials on the basis of price trends to establish the optimization of cost budget, especially for raw material rises in price risk of further detailed research, choose reasonable pricing tenderers.
Second, set up the cost control public evaluation system. Based on the cost of the complexity of the budget, and the bid invitation unit can take public evaluation way, choose the design unit of industry veteran as public evaluation party, the common participation in engineering bidding budget work, from the bidding phase of construction technology to a strict analysis and improvement, in order to reduce the cost of visa cause change frequency. Public evaluation units be adept in engineering design of the overall review, and find may have caused by lack of construction cost and increase the link, and then put forward rational Suggestions for improvement. At the same time, the tender inviting party should be taken to modes of encouragement, encourage bidders from design scheme found problems, this paper puts forward more rational process changes, the tender inviting party and public evaluation units to evaluation, and choose excellent unit.
Third, the bidding process of the system in operation and supervision of the subsequent agreed responsibilities. The bid invitation unit in the choice of bidding unit, should be clear that are involved in the construction of dispute solution to problems and supervision, from the point of view of the right to supervision unit, stronger supervision, and with strict engagement in the contract, subcontract, the engineering problems, such as the process changes have allowed conditions, and illegal operations should bear the legal responsibility. Through the ascension of their contract, and the bid invitation unit can choose cooperation unit with high quality, establish long-term cooperation relations, reduce the follow-up construction has cost problems disputes, form a virtuous circle of the cost control mode.
Cost control is a systematic work, in the bidding process, and the bid invitation unit should be based on long-term development, scientific choice of the design scheme, the comprehensive analysis of the engineering covers the cost factor, that estimate, estimates, the budget and final accounts to the results as far as possible, the service is good the whole process of construction.
