"B2 Project" switched to BIM technology

2021: Transition to BIM Technology

On February 16, 2021, Renga Software announced the transition of B2 Project to BIM technology.

According to the company, "B2 Project" needed to accelerate the working process, improve the detailing and development of project documentation, and therefore a decision was made to switch to BIM technology. In addition, from 2022, BIM will become mandatory in government order projects. To implement this transition, the Renga system was selected.

"B2 Project" began to use the system to create projects for the overhaul of apartment buildings, the company also planned to use it in the design of public facilities and industrial facilities. Later, the company participated in the tender for the development of a project for the modernization of the central heating station No. 1, located in Severobaikalsk. A prerequisite for the tender was the creation of a BIM model and the execution of the project within 190 days.

The central heat station in Severobaikalsk, with which it was supposed to work, was built in the 1970s, was repeatedly repaired, and its technical condition required complete modernization. Since it was not an old object, no original BIM model was discussed. Only DWG drawings were provided as TK. The specialists of "B2 Project" knew that in Renga they can be used as a substrate and thereby accelerate the process of working on the project. Having loaded the drawings into the program, they created the framework of the building, and then the CTP system itself (Figure 1).

The heat carrier in the design is hot water, which is supplied from boilers through pipelines to the CTP. The Automatic Routing in Renga (Figure 2) helped to cope with the creation and editing of pipelines much faster.

When constructing routes, the results of calculations obtained in the Danfos program were taken into account. Danfos performed hydraulic calculation, selected diameters of pipelines and shut-off valves. And on the basis of this data, during automatic routing, the desired diameters of network sections were immediately selected.

CTP is an object with a large number of various equipment. At the same time, some of them were already embedded in the system itself, and the remaining equipment, including heat exchangers, were imported into the system in the form of 3D models from the catalog of the Ridan manufacturer. Thus, they were able to achieve the necessary detail of the project (figure 3).

The project contains more than 170 equipment items.

On the basis of the created model, the necessary specifications and a set of design documentation were obtained (Figure 4), which is undergoing examination as of February 2021.

After the project passes the examination, installation work will begin.

It took a month to create a CTP modernization project. Earlier, when the company worked on a similar project in the drawing program, it took two months to implement it.

The company notes that now they can use the achievements of the project when fulfilling similar orders for the modernization or reconstruction of CTP in other regions. An order was also received for a project for the reconstruction of the Central Technical Center of Barnaul for the needs of Barnaul Heating Network Company JSC. In addition, in the near future, Renga plans to create projects for individual heating points for private residential buildings.
