Some project management information systems also include quality control and some office automation functions. (1) investment control function (1) data calculation and analysis of engineering estimation, budgetary estimate, budget, pre-tender estimate, contract price, investment use plan and actual investment; (2) Dynamic comparison of project budget, budget, pre-tender estimate, contract price, investment use plan and actual investment (such as comparison between budget estimate and budget, budget estimate and pre-tender estimate, budget estimate and contract price, etc.). ), and form various comparison reports; (3) Comparative analysis of planned capital investment and actual capital investment; (4) Make investment forecast according to the progress of the project.

(3) The schedule control function (1) calculates the time parameters of the project network plan, and determines the key work and key routes; (2) drawing a network diagram and a plane intersection diagram; (3) Prepare the resource demand plan; (4) Comparative analysis of the implementation of the schedule; (5) Forecast the progress of the project according to the progress of the project. (4) Contract management function (1) basic contract data query; (2) Inquiry and statistical analysis of contract implementation; (3) Standard contract text query and contract auxiliary drafting, etc. Third, the significance of the project management information system In the late 1970s and early 1980s, commercial software of the project management information system appeared internationally, and the project management information system has been widely used in the project management of the owners and constructors. The main significance of applying engineering project management information system is: (1) to realize centralized storage of project management data; (2) It is beneficial to the retrieval and query of project management data; (3) Improve the efficiency of data processing in project management; (4) Ensure the accuracy of project management data processing; (5) It is convenient to form various reports needed for project management.
