Abstract: Under the current tendering system,the role of tender documents is very important in specifying business competition for project works. A recently growing number of industrial evidences have demonstrated that many industrial problems,such as tendering rigging,collusive tendering,rent seeking,low bid price with low quality,labor dispute,are due to the inefficiency in construction business competition which is usually laid down in tender documents. Through content analysis on 376 used tender documents,this research serves to identify the most frequently factors for tender evaluation. The identified factors can be classified into three groups,namely conditional factors(CF),evaluating factors(EF) and decision factors(DF). It is found that practitioners has paid more attention to DF than the other two,and this consequently fails to favor an orderly operation of construction market and sustainable development of the industry. To improve the efficiency of the tendering system,it is recommended to develop and implement a credit system in the construction sector nationwide.
