“He lived his life in search of precise solutions, honest materials and ideas that make the world around us more reliable and better.”

Oleg Ivanovych Levchenko was born on 4 September 1946 in Volochysk, Podolia, in what was then the Kamianets-Podilskyi region. In 1950 his family moved to Proskurov, now Khmelnytskyi, where he spent his childhood and school years.

He grew up in a large family as one of four children. From an early age, responsibility, independence and respect for work became part of his character — not as abstract values, but as a natural way of life. During these years he also developed an interest in exact sciences and an engineering way of thinking: calm, systematic and demanding of detail.

After school he entered the Kyiv Polytechnic Institute, choosing the Department of Microradioelectronics. He graduated with honours — as a person for whom the principle of “doing it properly” was not a slogan, but an internal standard.

Life and Work

Oleg Ivanovych continued his professional career in science. In the late 1970s he worked at the V. M. Glushkov Institute of Cybernetics of the Academy of Sciences of the Ukrainian SSR, where he was engaged in applied scientific research and engineering design. His work was connected with state and industry projects, and a number of developments were protected by inventor's certificates and patents.

In time he became head of a specialised design bureau, while remaining not merely an administrator, but an engineer — precise, demanding and focused on practical results.

After the collapse of the Soviet Union, he did not leave science and engineering behind. Instead, his attention shifted towards practical solutions for everyday life — construction, thermal and energy-saving technologies, where precise calculation directly affects durability, comfort and the quality of the built environment.

He developed new materials, built technological processes, helped establish production and brought solutions to the point where they could work for decades. For him, inventing something was never enough. It had to work.

ECOS

Formation of an engineering foundation and philosophy combining precision, responsibility, resource awareness and practical application.

Engineering Legacy

The final years of his work became a natural continuation of everything that had come before. Oleg Ivanovych sought to create materials and systems in which engineering precision, environmental responsibility and practical applicability could coexist without temporary solutions or compromises that undermine the final result.

He did not see building materials merely as commodities, but as elements of the environment that should be predictable, durable and understandable in their behaviour. For him, durability was not only a technical characteristic, but also a form of responsibility — to people, resources and time.

This is how the engineering foundation of ECOS evolved — not as a single product or universal recipe, but as the result of many years of work with mineral materials, technological processes and applied engineering solutions.

Work with mineral systems, the possibility of reducing dependence on conventional cement, thermal storage technologies and other engineering directions developed around one principle: an engineering solution should be verifiable, practical and designed for long-term service.

Today this engineering legacy continues to evolve within the ECOS technology system.

ECOS Manifesto

ECOS is an engineering project, not a product line. We are not creating just another mix. We are developing a system of solutions based on engineering calculation, responsibility and respect for resources.

When a market competes primarily on price, short-term solutions can too easily become the result. We choose a different path — engineering integrity, durability and an understanding of how a material should perform under real conditions.

We offer more than a material. We develop an engineering philosophy that must be translated into real technological solutions.

We do not consider speed and cost sufficient reasons for compromises that undermine the final result.

For us, engineering integrity matters more than short-term savings. Reliability and service life should be considered from the beginning.

We seek to work with materials and technologies that can be controlled, verified and understood from an engineering perspective.

We see durability as a form of responsibility. Buildings and materials should serve for decades — not marketing cycles.

Environmental responsibility is not a slogan for us. We seek to reduce dependence on resource-intensive solutions through work with materials, local raw materials, thermal engineering and engineering design. The environmental effect of a specific solution should be supported by appropriate assessment and data.

ECOS is being developed for those who see construction as the creation of long-term value, not merely square metres.

We do not aim to create temporary solutions. We aim to create what should work for a long time — and work properly.

They build buildings.
We create the future of construction.
ECOS LEGACY

The engineering legacy of Oleg Ivanovych Levchenko became one of the foundations for the further development of ECOS. Today, 4Bricks s.r.o. develops ECOS as a mineral technology system while preserving the principles of engineering precision, practicality and responsibility for results embedded in this work.

A new generation of the team and its partners continues this work, adapting the technology system to modern raw materials, production conditions and specific applications. One principle remains unchanged: technology must be supported by engineering and must work under real conditions.

He is gone. But engineering ideas capable of changing the way we build continue to live on.
