【正文】 is imperative. Therefore, the lowest reasonable price of the successful bidder My future is the most important evaluation methods. At this stage due to the implementation of projects bill pricing model and the problems mainly against China at this stage in the minimum reasonable price of the principles of the successful bidder, most contractors have not yet set up their own enterprises of scale, panies unable to determine the reasonable Cost. This article is a scientific and fast set reasonable cost to study the key. First, from the project cost of the basic concept, of the engineering bill pricing model under the cost structure, to accurately predict costs of the project provided the basis, considering the average cost of the social cost to individual enterprises and the tender stage of the cost estimates. Followed through on fuzzy math and technology for smooth indepth analysis, through closedegree, the concept of reasonable fuzzy math and exponential smoothing technologies, construction of the project cost vague prediction model, and in accordance with the relevant information and statistics Information and experience to establish a framework structure, the parison works Construction Cost Management from the quantityone price plan model to price of separation volume model of the market, and gradually establish a market pricebased price formation mechanism, the price of the decision in the hands of the parties involved in the market, and ultimately the allocation of resources through the market in order to realize through the market mechanism to decide on project cost. This will standardize the construction marketpetitive behavior and the promotion of project bidding mechanisms play an important role in innovation. It can be said that the implementation of the project bill of quantities is a project cost management system in our country a big step forward, but also in China39。s decisionmaking ability and courage are closely related. Bidding documents is the general programme and play book of the bidding activity through the process of bidding. The bidding documents will specify that How to conduct each bidding work, how to dispatch bidding documents, the requirements for tenderer,how to rate and decide bidding and the procedures of bidding. Therefore, the personnel who is responsible for prepare bidding documents should first have a general view of the bidding work, include all the requirements and arrangements into the bidding documents. If meet problems that have not been considered previously, then resolve them one by one during the preparation. The course of bidding documents preparation is also the course of making bidding scheme . In another respect, bidding documents is also the legal instuments. Besides relevant law and rules, the bidding documents are the mon game rules that bidder,bidding agent and tenderer should subject to through the bidding. Bidding documents are the legal instuments that all the three bidding related parties should subject to, have legal force, therefore, the bidding documents making personnel required to have the awareness and quality of leagal in order to reflect the fair, just and legal requirement in the bidding documents. In building engineering bidding law enforcement and the practice of project construction supervision system on standardizing China39。曹之疾病學(xué)組。本文就是以科學(xué)、快捷的確定 “合理成本價(jià) ”為研究的關(guān)鍵。這對(duì)規(guī)范建筑市場(chǎng)的競(jìng)爭(zhēng)行為和促進(jìn)工程招標(biāo)投標(biāo)機(jī)制的創(chuàng)新發(fā)揮重要作用。本著“政府宏觀調(diào)控、企業(yè)自主報(bào)價(jià)、市場(chǎng)形成價(jià)格 ”的原則，來推行實(shí)施工程量清單計(jì)價(jià)規(guī)范。本工程招標(biāo)文件根據(jù)《中華人民共和國(guó)招 投標(biāo)法》規(guī)定，對(duì)投標(biāo)人，投標(biāo)企業(yè)進(jìn)行嚴(yán)格把關(guān)，對(duì)競(jìng)標(biāo)者提出了專業(yè)性的要求，對(duì)工程的概況進(jìn)行了說明。 從另一個(gè)意義上來講，招標(biāo)文件也是法律文件，除了相關(guān)的法律法規(guī)外，在招標(biāo)的全過程中招標(biāo)人，投標(biāo)人，招標(biāo)代理機(jī)構(gòu)共同遵循的游戲規(guī)則就是招標(biāo)文件，這是參加招標(biāo)工作三方人士必須遵循的法律文件，具有法律效力，所以編制招標(biāo)文件的人員須有法律意識(shí)和素質(zhì)，在招標(biāo)文件中體現(xiàn)出公平、公正、合法的要求。本文從降低成本、增加收入兩方面闡述對(duì)施工成本的有效控
