BIM in Practice: ASPRO Engineering Company on Delivering Project Using Renga Professional

Success in modern design and construction belongs to those who can work not only quickly but also comprehensively. Building Information Modeling (BIM) technology has moved beyond being just a trend – it has become a new standard that defines the quality, speed, and efficiency of creating complex facilities. However, for many companies, the transition to BIM is still associated with myths about complexity, high costs, and lengthy implementation processes. The successful experience of Russian design companies proves otherwise.

ASPRO, Chelyabinsk-based engineering company has completed the design of one of the largest resort facilities in the region – 'Magic of Warmth' thermal complex. The project's distinctive feature is that it was developed entirely in the home-grown Renga Professional BIM software, demonstrating readiness for complex and non-standard design challenges.

Covering more than 6,000 square meters and designed to accommodate up to 1,400 visitors, the complex includes a main building with two indoor pools, three outdoor pools, and a bathhouse. The design team faced a challenging task: the building featured complex floor plan geometry, an expressive elevation with diverse finishing materials, and numerous custom-made elements.

“We immediately felt the advantage of working with a complete 3D model of the entire building rather than with fragmented drawings," says Polina Gorshkova, Development Director at ASPRO Engineering Company. The company selected Renga Professional in 2018 after recognizing the benefits of enabling all project stakeholders to collaborate within a single environment.

The architects modeled all walls exclusively using the profile tool, despite the large number of inclined surfaces. Windows and curtain walls, most of which were custom-manufactured, were assembled as complex assemblies. One of the team’s main achievements was the modeling of the pools, featuring curved shapes and numerous technological openings.

Structural engineers produced 456 reinforced concrete drawings, while MEP engineers fully developed the ventilation, heating, and water supply systems. The ventilation system schedule alone consisted of 111 sheets. A key factor in the project’s success was the ability for 8–10 specialists to work simultaneously within a single model, allowing them to coordinate solutions efficiently and avoid clashes.

The company went beyond conventional design practices by providing the completed digital model to interior designers. This allowed creating a design concept that incorporated all engineering systems from the outset rather than serving merely as visualization.

The project successfully passed a non-state expert review based on drawings generated directly from Renga Professional. All review comments were addressed in a timely manner. The development of the working documentation took 11 months, while construction required approximately the same amount of time.

“We have observed approximately a 30% reduction in the time required to produce architectural and structural working drawings. More importantly, we can see how accurately our digital model is translated into reality,” notes Polina Gorshkova.

ASPRO’s experience is a clear example of how a domestic BIM solution can successfully address real-world, large-scale challenges while reducing project timelines and improving design quality.
