Building structure modularization is realized through BIM modeling technology, and rapid mass production of modules is realized through 3D printing technology, wherein, from three basic dimensions of resource, behavior and delivery of BIM design process, specific methods and practical contents of implementation standards of design enterprises are given. BIM (building information model) is not simply an integration of digital information, but an application of digital information, and can be used for a digital method of design, construction, and management. The method supports the integrated management environment of the building engineering, can obviously improve the efficiency of the building engineering in the whole process of the building engineering and greatly reduce the risk; 3D printing (3 DP), a rapid prototyping technique, is a technique that uses bondable materials such as powdered metal or plastic to build objects on a digital model file basis by means of layer-by-layer printing, and 3D printing is typically implemented using a digital technology material printer. Often in the fields of mould manufacture, industrial design, etc., are used to manufacture models, and later gradually in the direct manufacture of some products, parts have been printed using this technique.

The prior municipal engineering construction has weak safety awareness, defects in safety management and unhealthy safety system, and a complete municipal engineering construction safety control method is not formed, so that the development of municipal engineering is restricted to a great extent, and the urban construction of rapid development at present is difficult to meet.
BIM technology has become important technical support in municipal engineering construction and management work, also is the important sign of construction informatization management. The municipal engineering construction safety control system based on the 3DGIS+BIM technology is constructed, so that a constructor can accurately grasp the operation specifications of construction site personnel and machinery and whether safety requirements are met, and safety accidents caused by non-compliance behavior operation are avoided; meanwhile, the stress condition of the municipal building in the construction process is mastered in real time, and dangers possibly appearing in the construction site are predicted and evaluated in time, so that the predictability and controllability of the safety of the whole municipal engineering project construction link are enhanced, and the digitizing, visualizing and intelligent level of the municipal building can be remarkably improved.
Therefore, it is necessary to construct an engineering management platform based on the BIM model and 3 DGIS.
