User experience / Creating Industrial Building 3D Model with Renga BIM System

Renga Software provided Saratovzapsibniiproyekt-2000 with server-based worksharing in order to design the industrial building project.


Enterprise: Saratovzapsibniiproyekt-2000

Field of work: residential and commercial buildings design, MEP building systems design, general land use planning

Location: Saratov


Saratovzapsibniiproyekt-2000 is the research, development, and design institute, established in 1997 in Saratov. Since 2006 Saratovzapsibniiproyekt-2000 has been providing front-end engineering design services for dozens of major projects, including construction works and building renovation projects. Company experts design complex building systems including HVAC, plumbing and electrical systems using AutoCAD software.

Managing all their design workflows separately, team members failed to communicate effectively. This resulted in missed construction deadlines, hampered team perfomance and misunderstanding. It was essential to find a new tool to improve multi-discipline coordination and facilitate team cohesion.


Designers were familiar with worksharing, a design method that lets multiple team members work on the same project model at the same time, which is critical for collaborative design in BIM. That is why company experts were searching thoroughly for the right BIM software. They tested many products, but eventually decided on the Renga Software BIM system. The benefits of Renga for BIM project team are quantifiable. Renga users are provided not only with collaboration feature, but with the wide range of tools meaning to aid project delivery and asset performance. To test all the Renga features, it was decided to implement a pilot project of the control building for submersible pumps with open spaces for equipment storage.


The control building for submersible pumps is a single story rectangular-shaped building with sandwich panel walls. External walls are 100mm thick and heat insulated with the mineral wool. Internal walls are 80 mm thick. They are also heat insulated with the mineral wool. Walls of fire compartments are designed in compliance with the fire safety regulations. REI 150 fire-resistant walls are 120 mm thick. Roof is cladded with sandwich panels and designed with 7 degree pitch (fig. 1).

When designing reflected ceilings and partitions (interior walls), engineers used Knauf product catalogue on

The Room tool helped to create inner layouts and define room boundaries (fig. 2).

Renga BIM system provided designers with required room schedules and 7 degree cabinet projection (fig. 3).

Designers also generated all required elevations and sections (fig. 4).

Renga community server has allowed multiple team members to work on the same project model at the same time. Community server provided early access to architectural model for MEP engineers. Worksharing helps MEP engineers and architects to coordinate the design process, make the right space-planning decisions, adopt rational  structural concepts and capture design intent, saving time and boosting  productivity. This feature reduces the chance for discrepancies between architectural, structural and MEP models, validating the accuracy and consistency of the model.

The exhaust duct system was designed in stages. To start with, MEP engineer installed vent hoods on the roof in the 3D view. Then, the engineers specified the routing points of the vertical vent stacks. Finally, using Automatic Routing tool, engineers generated ventilation routes between the points and the exhaust hoods. The tool combined all model objects into one system,  assigned sections and materials to the ducts according to the engineers' intent.

Similarly, the supply duct system was designed by creating a route between start and end points. Air handling unit, reducers, and elbows were installed on the duct route.

Ventilating grills provide natural ventilation in the process rooms.

Engineers used handy and helpful Automatic Routing tool to layout duct routes in the project. When the adjustments were needed, MEP engineers relocated the routes to the correct place.

Water distribution and sanitary waste systems were also created mainly in the automatic mode (fig. 6).

Right after the routing part had been completed, engineers generated all the required documents (fig. 7).

The design of the technological parts of the project was being initially implemented in 2D AutoCAD software. Afterwards designers switched to KOMPAS-3D.

It took two months for the team to create the control building 3D model. Notably, designers didn't give up their other tasks.


Using Renga BIM system, company experts implemented a pilot project of the control building for submersible pumps with open spaces for the equipment storage. The Renga community server was used at all stages of the design process, improving the collaboration between all project members and increasing efficiency. The server undoubtedly sped up the stakeholders' work, allowing multiple team members to work on the same project model at the same time.

Building Information Modeling technology helped to unveil and amend errors introduced during the 2D design process. 3D modeling also automatically provided stakeholders with all the required drawings and schedules. BIM also significantly reduced the time for document preparation.

Olga Shustova, architect of Saratovzapsibniiproyekt-2000:

«Companies of all sizes are facing a digital imperative: introduce new technologies effectively or face competitive obsolescence. Our company's management always strives to build a better design workflows. As a young professional I was delighted when our management decided to implement Renga BIM system. Renga highly qualified specialists were happy to provide corporate training. This software is intuitive and easy-to-use. After a couple days of training, the group was ready to start working on the project. Renga software supports worksharing, a design method that allows multiple team members to work on the same project model at the same time. This efficient feature provides a more consistent modeling experience and enables better collaboration among stakeholders»
