«He lived his life in search of precise solutions, honest materials and ideas that make the environment around more reliable and better»
Oleg Ivanovich Levchenko was born on 4 September 1946 in Volochysk, in Podolia, in the then Kamenets-Podolsk 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, one of four children. From an early age, responsibility, independence and respect for work were formed in him — not as abstract values, but as a natural way of life. It was during these years that his interest in the exact sciences and engineering thinking took shape — calm, systematic and demanding of details.
After school he entered the Kyiv Polytechnic Institute, choosing the department of microradioelectronics. He studied with distinction and graduated with a red diploma — as a person for whom the principle of “done correctly” was not a slogan, but an internal standard.
Life Path
The professional path of Oleg Ivanovich continued in the scientific environment. 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 and design activities. His work was connected with state and industry projects, and the developments were protected by numerous author’s certificates and patents.
Over time he headed a special design bureau, remaining not a desk administrator, but an engineer — precise, demanding and oriented toward real results.
After the collapse of the Soviet Union he did not abandon science and engineering. On the contrary, his interest shifted to practical solutions for real life — to construction, thermal and energy-saving technologies, where precise calculation directly affects durability, comfort and the quality of the environment.
He developed new materials, built technological processes, raised production facilities and brought solutions to a state in which they can be used for decades. For him it was important not simply to invent. It was important — to make it work.
Milestones
Birth in Volochysk, Podolia.
Family move to Proskurov (now Khmelnytskyi).
Kyiv Polytechnic Institute. Department of microradioelectronics, red diploma.
V. M. Glushkov Institute of Cybernetics. Applied research, state and industry projects, author’s certificates and patents.
Development of materials, technological processes, creation of solutions oriented toward durability and real application.
Formation of an engineering system and philosophy that united precision, environmental responsibility and practicality.
Engineering Legacy
The last years of his work became the logical outcome of the entire path travelled.
Oleg Ivanovich strove to create materials and systems in which engineering precision, environmental responsibility and practical applicability exist simultaneously — without compromises and temporary solutions.
He saw building materials not as a commodity, but as an element of the environment that is obliged to be honest: predictable, durable and understandable in its behaviour. For him durability was not a technical characteristic, but a form of responsibility — before people, resources and time.
This is how the ECOS system appeared — not as a separate invention and not as a commercial product, but as the assembled formula of his entire engineering life. Dry building mixes with minimal Portland cement content or without it, technologies of concrete heat accumulators, ecological fillers and crushed stone of a new generation became a continuation of the same principle: engineering must serve for decades, not marketing cycles. ECOS became not the result of one project, but the outcome of engineering thinking formed by years of precise calculations, practice and responsibility for the result.
Манифест ECOS
ECOS is an engineering project, not a product line. We do not create yet another mix. We create a system of solutions based on precise calculation, responsibility and respect for the resource.
While others compete on price and participate in a race to the bottom, the result is faceless and short-lived buildings — first harming the environment during production, and then during demolition. We do not participate in this race.
Others sell bags of cement and sand. We offer an engineering philosophy embodied in the material.
Others make compromises for the sake of speed and cost. We refuse simplifications that destroy the result.
For us, engineering is above accounting. Decisions are made based on reliability and service life, not short-term savings.
We work with honest materials: controlled in composition, predictable in behaviour and transparent in logic.
We perceive durability as a form of responsibility. Buildings must serve for decades — not marketing cycles.
Ecology for us is not a slogan. Reduction of CO₂ is achieved through the material, thermal engineering and engineering calculation, not through “green” marketing.
ECOS is not created for everyone. It is intended for those who build a legacy, not simply square metres.
We do not make temporary solutions. We make what must work for a long time — and work correctly.
They build buildings.
We create the future of construction.
ECOS LEGACY
ECOS is based on the engineering work of Oleg Ivanovich Levchenko and is commercially developed by the company 4Bricks s.r.o.
Today the technology is being developed by a new generation of engineers and partners who continue this path. The principles of precision, durability and responsibility for the result remain unchanged — and are applied to modern construction tasks in different countries, climates and regulatory environments.
He is gone. But the ideas that change the approach to construction live on.
