Effective designing of technological processes of maintenance and repair of engineering products is currently difficult and complex engineering problem with many inputs and constraints. It should be resolved at the interface of such areas of knowledge as engineering and construction of buildings and structures. Engineers-mechanical engineers to build computational models and design of means of mechanization used methods of theoretical mechanics, theory of mechanisms and machines, strength of materials, machine parts and design principles. Civil engineers (architects), in turn, responsible for the development of infrastructure for a specific production, climatic and other factors.

In now terms of rational combination of architectural and engineering features engineering project, consisting in the use of so-called BIM-technology (from the English Building Information Modeling) - a process of collective creation and use of information about the facility, forming a reliable basis for all decisions throughout the life cycle of the object. In Fig. 1 shows the BIM-model of the building fixed the maintenance and repair of vehicles executed in the environment of architectural CAD.

BIM-technology involves the construction of an accurate virtual models of buildings in digital form. The use of models facilitates the design process at all stages, providing a more thorough analysis and control. Once finalized, these computer models contain precise geometry of the structure and all necessary data for material procurement, fabrication and construction works. Among the main advantages of using BIM technologies - digital precision projects, absolute clarity and understandability for the customer at the expense of 3D imaging with huge savings of design time, significant reduction in the cost of construction and operation.

But most important, in our opinion, the advantage of this design technology is a unique capability of integration in a virtual environment BIM-models of any other objects of technological environment, as designed by the user in the environment, different CAD and borrowed from other libraries and databases of 3D-models. This approach provides a great opportunity to implement integrated (cross-cutting) the design of any infrastructure facility, which is called "turn-key" from its saturation with any hardware, create any project documentation (specifications, drawings, etc.). Moreover, in the electronic model can be built and saved several variants of structures and placement of equipment. All of this could be the basis for impressive presentations, discussion and choosing the most rational version for further implementation "in the metal".

In Fig. 2 shows a fragment of the implementation of BIM technologies in image e model stationary vehicles maintenance and repair of vehicles with a high degree of detail, performed in the environment of architectural CAD. The machines and equipment of work posts imported from third-party libraries. Digital model of the electromechanical drive the traction conveyor (Fig. 3) performed by the authors in the engineering CAD environment.

The detailed calculation of the working body of the pipeline comprising: master and slave sprockets and the traction plate chain were run using Excel spreadsheets (Fig. 4) and parallel digital simulation in environment engineering CAD. This technology allows to obtain not only optimal from the point of view of the theory of the strength of the design, but also to test each pair for intersection, and ensuring the required degree of freedom with subsequent visualization, animation, and, if necessary, the implementation of the working project documentation in semi-automatic mode.
