The construction project bid evaluation is a typical multi-objective decision-making problem. Considering the content of the construction project bid evaluation, an appraisal index system of the construction project bid evaluation was established; The reasonable range of index values which can reflect the tenderer preference was utilized to perform standardization of evaluation indicators; The optimal grey relational grades for bidder were determined by gray relational model, and the optimal decision-making conclusion for bid evaluation was made after comparison of the optimal grey relational grades. The model had the advantages of complementary of theory and experience, strong operability and scientific quantify, therefore popularized the grey correlation model application in construction project. © 2011 Published by Elsevier Ltd.
