Big projects carry big risks. We are there for you every step of the way. Concelex is the turnkey solution for construction works. The company provides fully integrated design & build services across most areas of expertise – buildings, civil engineering, infrastructure and energy.


25 years ago, development in the construction sector was a sprint. Nowadays, we see it as a marathon full of innovative solutions, trustworthy execution, flexibility, reliability, and time-value efficiency. Our portfolio includes design and build solutions for office buildings, exhibition centers, hotels, educational units, residential compounds, nuclear facilities, cooling towers, slag and ash storage facilities, complex metallic structures, logistic spaces, water supplies, draining systems, and road networks.


From shopping centers to residential compounds, workplace solutions, industrial projects or educational units, we deliver complete design & build solutions for your projects, as well as warranty-period monitoring.


We manage every stage of a building project, providing highly skilled workforce, harnessing innovation and using advanced equipment.


We become partners for institutional companies – real estate developers, private equity funds and the public sector (Government, national companies, local authorities), helping them turn their investment plans into reality.


In our energy projects, we bring power generation infrastructure solutions into the 21st century for cooling towers, nuclear facilities, turbine equipment halls or electrolysis stations, always with a keen attention to detail.


With the country’s largest energy suppliers and the National Nuclear Company as our partners and clients, as well as erecting the only hyperbolic cooling tower newly built in Romania in the last 30 years, we are engaged in energy projects across Romania, leveraging the company’s top assets: engineering services, specialized workforce, quality execution works, comprehensive view and attention to detail. We analyze every detail of a project, set up clear objectives and priorities, carefully manage and supervise the process, and identify and resolve problems in the shortest possible time.


Be it roads, bridges, railways or stadiums, we provide every construction site with interrelated professionals to keep the project in sync, on-time, and on-budget, for bringing people closer together in order to support progress and economic development.


Our project managers have extensive experience in high-profile projects, identifying potential problem areas early on and leveraging their practical knowledge to manage virtually any type of infrastructure project.

Civil Engineering

Encompassing protective structures, retaining walls, large-scale sewage treatment plants, water treatment facilities or industrial buildings, we expertly provide cost-effective planning, engineering and building services.


We provide nation-wide civil engineering services, assigning specialized technical and management teams that can provide turnkey solutions for each project. To Concelex, civil engineering translates into the ability to manage large-scale projects meticulously while keeping the big picture in mind as such large-scale works require.
