SCOPE OF ACTION & SERVICES
Our portfolio includes a wide range of structural and civil engineering projects across Greece, combining technical excellence, architectural quality, and long-term durability. Below are key categories that reflect the diversity of our experience:
New Buildings
We collaborate with leading Greek architects to deliver structural designs for buildings made of reinforced concrete, structural steel, and masonry.
Our portfolio includes projects of high architectural and functional standards:
Residences • Commercial buildings • Museums • Educational facilities • Hotels • Industrial complexes • Parking structures
Addressing the growing need for renovation and adaptive reuse, we specialize in the assessment, strengthening, and restoration of existing structures.
Using advanced analysis software, we design pre-seismic and post-seismic interventions for reinforced concrete, steel, and masonry buildings, as well as monuments and listed heritage structures, always respecting their architectural integrity.
We provide value engineering and redesign services for existing structural studies, aiming to reduce costs and construction time while maintaining top-tier quality and safety standards.
Our team has extensive experience in the design of civil infrastructure works, including:
- Slope retaining structures
- Temporary and permanent foundations in challenging geotechnical conditions
- Subsurface works within groundwater environments
- Box culverts and road structures
- Bridges and small-scale infrastructures
We ensure the faithful implementation of our designs through systematic on-site supervision, including:
- Regular site inspections
- Photographic documentation and reporting
- Preparation of detailed “As-Built” drawings
For private projects of small to medium scale (residences, offices, etc.), we offer comprehensive construction management services, covering:
- Coordination of contractors and trades
- Budget management and cost control
- Schedule monitoring and progress reporting
