According to the management mode of large-scale design institute and the application example of Scivic Engineering Corporation, this paper presents a framework for SOA-based Integrated Management Information System of large-scale design institute and introduces the developing process and implement of this system, which can be referenced by exploration and design institute.

Currently the application of BIM technology in the decoration industry is still ina groping stage.The author choosessome key space of a decoration engineering project, and makes an attempt to establish a data integration solution with three-dimensional model using Revit as a core software. The author adopts BIM technology in the whole process of scheme design, detailed design and construction process.In scheme design stage, some key space is selected and a BIM model is built, an effect diagram is rendered and a roaming animation is produced; in detailed design stage, the decoration BIM modelis detailed, HAVC, water supply and drainage systems, electrical system, fire fighting and drenches system are integrated in the model to avoid collisions between these models, and at the same time a decoration construction plan is produced; in construction stage, the BIM model not only provides a visualized operation guidefor workers, but also exports an adornment material list to guide the materail procurement and cost control. These practices help us to summarizethe principles and methods in the whole process of BIM technology's application in the decoration engineering, and evaluate it's application effects. These experieces and practice might serve as referencesfor the application and promotion of BIM technology in decoration projects.
