51x51m PEB & RCC Warehouse Design

I’m building a fish-feed factory and need a 51 m × 51 m warehouse dedicated to raw-material storage. Side wall height will be 9M out of which 8 feet will be brick wall and remaining will be cladding. The structure must combine a PEB super-structure with RCC foundations and grade slab, optimised for both cost and durability. The job covers the full design cycle—no partial work. I want clear structural calculations, economical member sizing, and a presentation-ready 3-D model Please factor in: • Uniform floor loading for stacked ingredient bags (exact figures follow) • Provision for a 5-ton EOT crane on the central bay • Future extension on the north and east sides • Standard wind/seismic loads to IS codes (or equivalent) Deliverables I will review and sign off: • Complete structural design report with load assumptions and calculations • GA, fabrication, and shop drawings (DWG & PDF) for the steel frame • RCC footing, pedestal, plinth beam, and grade-slab drawings with bar schedules • Connection details and bolt schedule • Material take-off / BOQ showing steel and concrete quantities • Fully navigable 3-D model/render (Tekla, Revit, or similar) Time is critical—I’d like to break ground as soon as the package clears local approval, so work to an ASAP schedule. Submit a detailed project proposal outlining your methodology, the software you plan to use, interim milestones, and the hand-over format. I will supply the geotechnical report and any remaining load data immediately after kickoff.
