Research On Optimization Of Construction Project Bid Evaluation Method

The construction industry is one of the important pillar industries of national economy in China. Due to the end of 2014, there are 81141 construction enterprises and 49.6058 million employees all over the country; and the total value of output in the construction industry is up to RMB 17671.3 billion and occupies 27.76% of the gross national product (GDP) of this year. The sustainable, quick and healthy development of the construction industry has an important and profound effect on the national economy of China.In comparison to the Western developed countries, it is not long before the construction industry introduced the bidding system in China. Both the theoretical research and the practical application start relatively late. Facing the development brought by the deep reformation of our country, the existing construction project bid evaluating and determining methods are not adapted to and matched with the reality and cannot play the huge promoting role of the construction project bidding system. For over thirty years, the base price winning method in the early stage, the base price-free winning method in the medium stage and the reasonable low-price bid winning method and comprehensive bid evaluating method applied for the recent ten years cannot reach an agreement in theory and thoroughly solve the developing problem of the construction project bidding of our country in practice. The lowest-price bid winning method commonly used in the Western developed countries accords with the market economy competition and is provided with theoretical scientificity and practical feasibility, but does not accord with the national situations of our county; and from the practical operation, the low-price bid winning method cannot effectively reduce the construction cost, but brings many problems to the building market, for example, power rent-seeking, security accidents an quality accidents frequently occur in the bidding process so that the quality degrades, the phenomena such as bid failure, bid accompanying, bid colluding and subcontracting frequently occur, and the enterprises in the building industry compete for the cost in the long term so that the condition of high output value and low profit exists in the long term.Based on the specific historical background,research status of our country, and the research of the development of the construction project bidding system of our country in detail and a lot of facts, the test proves that the lowest-price bid winning method is not suitable for wide application at present and a brand new construction project bid evaluating and determining method is raised:a weighted average compound base price method. Based on the value of u determined by the communication of the tenderers and the bidders, this new methodmeans that the final contract price equals the bidding price multiplied by u, with the addition of other bidding prices multiplied by (1-u). Subsequently, the text demonstrates the advancement and feasibility of the method through correlative theories and raises a series of correlative supporting measures to ensure the smooth implementation and the function exertion according to our national condition...
