Abstract: In order to promote information technology management and to improve construction management technology, the project realizes information technology management through the establishment of BIM5D application platform, connection of cloud coordination office platform, and BIM virtual model guiding system. Through the application of BIM technology in intelligent backform platform and supporting on-site resources progress control, the project improves the management of on-site quality, safety, progress and cost, improves the quality and efficiency of project managers, realizes on-site data summery, builds up database for the company and greatly improves the project construction management technology. Based on BIM cloud platform, the project realizes standardization through information technology, specialization through standardization, refinement through specialization, which improves construction efficiency, realizes refinement management and the general contract management of the project.
