Gemo a.s. Completes Structural Shell of OLOE Building Two Months Ahead of Schedule

Gemo a.s., acting as the general contractor, has successfully completed the structural shell (rough construction) of the OLOE building, the first structure within the extensive Smíchov City South urban development project by Sekyra Group. The role of general contractor involved complex coordination of all construction works, subcontractor management, quality assurance, and strict adherence to the project timeline. The successful completion of the OLOE building two months ahead of schedule is the result of precise project management led by Igor Klajmon, Development Director at Sekyra Group, and the professional approach of the entire execution team under Jiří Dostál, Manager at GEMO.

Smíchov City represents one of the most significant urban development projects in the Czech Republic. A modern district is being created on the site of the former freight railway station in Prague’s Smíchov, featuring nearly 400,000 m² of mixed-use space. This includes residential, commercial, and administrative functions, complemented by extensive public infrastructure.

The southern part of the Smíchov City project is predominantly commercial and administrative in character. It includes the new headquarters of Česká spořitelna, office buildings, a hotel, retail spaces, parks, pedestrian and cycling zones, a planned school, and a connection to the new Smíchov Station transport terminal.

Technical Complexity Requires Precise Execution

The OLOE building, with design preparation managed by the CASUA architectural and design office, presents several specific technical challenges. Construction is scheduled to take place over three years. The building’s foundations, consisting of deep large-diameter piles, were constructed within the protection zone of Metro Line B. Furthermore, 50 geothermal boreholes were drilled with a total length exceeding 10 km. These will provide the building with heat for future heating needs, while the borehole system will also allow for cooling during the summer months. All the primary advantages of geothermal energy are utilised here: renewability, stability, and environmental friendliness.

Key Project Milestones

“A crucial moment of the execution was the completion of the load-bearing monolithic reinforced concrete structure, where we managed to carry out the final ceiling concrete pour before the end of 2025,” says Project Manager Jiří Dostál, adding: “This milestone has allowed us to proceed with the subsequent phases of construction according to an optimised schedule.”

The Future Within Reach

The completion of the OLOE building represents the first stage of the extensive Smíchov City South project. In the coming years, construction of further buildings will continue, gradually creating a complete urban district with full infrastructure, public spaces, and services. Upon completion, Smíchov City will function as a compact, traditional part of the city, offering modern housing, employment opportunities, shops, restaurants, services, and civic amenities. It will feature a school, medical care, cultural and sporting facilities, as well as green spaces for relaxation.

We are very pleased that GEMO can participate in this development and be part of what is currently the largest construction site in the Czech Republic.

Key Technical Parameters of the Project:

• Foundations: Deep large-diameter piles within the Metro Line B protection zone.
• Geothermal Energy: Over 10 km of geothermal boreholes for eco-friendly heating and cooling.
• Structure: Load-bearing monolithic reinforced concrete construction.
• Construction Period: 3 years.
• Handover of Structural Shell: Two months ahead of schedule.
