Structural Design
The Structural Design today faces challenges of increasing complexity. Computational calculations and predictive models enable optimization of structures beyond traditional limits.Interdisciplinarity between structural engineers, geotechnical experts, and architects becomes crucial for conceiving high-performance buildings that meet contemporary safety, functionality, and aesthetic requirements.
Structural Design: Integrated Solutions for Industrial Buildings and Complex Infrastructure
The Structural Design is the foundation of every complex construction work, ensuring safety, functionality, and durability. 3i Group has developed an integrated approach that surpasses traditional compartmentalized vision, combining multidisciplinary expertise to tackle highly complex industrial projects.
The integration between Structural Design and MEP Design constitutes a fundamental competitive advantage, enabling space optimization, interference reduction, and full functionality assurance for every system.
3i Group engineers employ advanced calculation software to simulate structural behavior under various load conditions, including exceptional events such as earthquakes, fires, or unexpected overloads. This analytical approach enables identification of potential critical issues before the construction phase.
The Structural durability is ensured through careful selection of materials and construction technologies, considering specific environmental and operational conditions of each industrial project. Proposed solutions optimally balance technical requirements and economic sustainability.
Structural Project: BIM Methodology and 3i group Multidisciplinary Approach
Structural project today means adopting innovative methodologies that surpass traditional approaches. 3i group fully integrates Building Information Modeling (BIM) as the central tool of its design process, creating integrated digital models containing all relevant information about the work.
This methodology enables real-time interdisciplinary coordination, drastically reducing inconsistencies between different design components. The BIM approach also enables advanced clash detection, ensuring that structures, systems, and finishes can coexist without conflicts.
The Information traceability becomes a strategic advantage, facilitating change management and keeping project documentation constantly updated. Every element is coded according to international standards, facilitating communication and interoperability.
The work lifecycle is integrally considered, from initial conception to final demolition, enabling informed choices regarding maintainability, future flexibility, and sustainability. This holistic approach translates into more efficient and forward-looking projects.
