About OSD Engineers
OSD Engineers formerly known as EIS Planners and Engineers is a Structural consultancy firm possessing broad expertise of in Structural Engineering across various sectors. Under the leadership of veteran structural engineer Mr. Biswajit Som (visiting Faculty Jadavpur University) & Mr. Dipesh Chandra Barua the organisation began its journey 25 years ago. In the year 2022 OSDE was formed by Mr. Biswajit Som. We as a firm is responsible for various structural engineering tasks to ensure safe, efficient and durable structures. Starting from detailed design of broad infrastructures we also have expertise in Assessment of aged infrastructures. To corroborate our statement here’s a brief overview of the structural works involved from our project experience.
- Conceptual & Feasibility Analysis – Evaluating project requirements, site conditions, and structural feasibility while considering cost, environmental impact, and regulatory compliance.
- Structural Design & Analysis – Using advanced modelling software to design bridge superstructures (decks, girders, cables) and substructures (piers, foundations, abutments), industrial shed structures, building structure (commercial, residential), offshore structures (long span Jetty, Dolphins, Fixed ramp/ Linkspan structures) based on load calculations, seismic considerations, and material strengths.
- Material Selection & Specification – Determining appropriate materials, such as reinforced concrete, steel, or composite materials, ensuring durability, strength, and compliance with standards.
- Foundation Design – Developing appropriate foundation solutions, such as shallow foundations or deep pile foundations, based on soil analysis and geotechnical conditions.
- Seismic Resilience Design – Ensuring industrial and building structures are engineered to withstand seismic forces using base isolation, damping systems, and ductile detailing.
- Construction Support & Supervision – Assisting contractors with execution, reviewing structural integrity, ensuring adherence to design specifications, and addressing unforeseen challenges.
- Inspection & Maintenance Planning – Conducting structural health monitoring, periodic inspections, and recommending maintenance strategies to ensure long-term bridge performance.
- Structural Assessment & Retrofitting – Evaluating existing structures for strength, stability, and compliance, followed by reinforcement or retrofitting solutions to enhance longevity and performance.
