Research conclusions:The engineering information management system is built on the base of the Internet according to the construction features of the Major Bridge Bureau． (1) The system has three － level systematical structure in the overall structure， and with the management pattern based on C /S， the system extendibility can be ensured．(2) Application of the engineering information management system can reduce the engineering management personnel＇s working strength，and the all construction informations of a project can be written into the system by one person and shared by others．(3) The system interface is simple and clear with fresh sensation． (4) This system has many functions，such as building construction standing book and consulting and revising the construction information．(5) Most information are called out and generated from the data bank of the system for user convenience． In this way，the writing of user can be much reduced and therefore，the errors caused by the writing can be reduced，the system burden can be cut and the working efficiency can be much enhanced． I
