Space Construction Bidding And Evaluation Research

Bidding is one bargaining way in construction market. With our country's entry to WTO and the deeper reformation and opening, there are more and more construction projects in our country .it's same to aerospace construction engineering. This paper firstly made some research on bidding actualities of construction engineering in China and analyzed the existed problems. Then in order to consummate the bidding in aerospace system, this paper established bidding system based on these researches and analysis, and improved the comprehensive quantificational bidding evaluation method and analyzed some problems which appeared in the process of applying the lowest method of evaluating bid price. Finally, considering the bidding flow, it gave some constructive suggestions in this paper about how to avoid the risk of bidding in aerospace construction engineering. The main contents of this thesis are outlined as follows:(1) It made some investigation and study on the present construction engineering bidding methods, rules and bidding evaluation methods, and analyzed the problems existing among the process of bidding presently. Then it summarized some technique of process controlling to evade the risks of bidding of aerospace construction engineering.(2) It summed up the universal content of bidding indexes in construction engineering, and proposed the means of choosing and building the bidding index system based on investigating to the experts according to the characteristics of a special engineering project. This method would help to avoid the lack of the constantly unchangeable indexes system in present bidding evaluation methods.(3) It analyzed the present bidding evaluation methods contrastively. To resolve the disadvantages of the present comprehensive quantificational bidding evaluation method, it made some improvement by integrating Analytical Hierarchy Process (AHP) and fuzzy Optimization. And then it proposed the bidding evaluation method based on AHP and comprehensive fuzzy evaluation, and analyzed the principles and methods to quantify and standardize the indexes. At the same time it found a biding evaluation model with a practical example of aerospace construction project.(4) With an example, it summed up the preconditions to use the lowest reasonable method of evaluating bid price in aerospace construction engineering, and it summarized the methods to optimize the bidding price (considering capital current-valued cost and economical converting of the time limit for a project).This work made the lowest reasonable method of evaluating bid price more standard and reasonable.
