Project Overview: We require a structural analysis, member optimization, and a detailed 2D/3D drawing package for a lightweight, single-slope steel structure. The structure will be built completely indoors beneath an existing outer "Iskurit" shell (fully protected from wind load/uplift).The entire frame is strictly restricted to Standard Steel Hollow Sections (SHS/RHS) and must be designed for a 2-person construction crew to manually lift, align, and bolt together on-site with zero crane access. All longitudinal beams must sit flush inside the primary rafters to maximize interior vertical clearance. Key Deliverables Required: 1. Structural Calculation Report: FEA/Analysis optimizing member sizes to achieve the absolute minimum steel weight. 2. 3D BIM Model & 2D CAD Drawings: Native Autodesk Revit (.rvt) or AutoCAD (.dwg) files. These must be clean, editable, and ready to pass to a local structural engineer for final stamp/sign-off. 3. Connection Details: Detail sheets for ground-welded shop plates and on-site bolted connections. 4. Final Bill of Materials (BOM): Fabricator-ready cut list with weights. Technical Constraints & Dimensions: * Footprint & Geometry: Stepped layout. Total length is 9.00 meters. Main span width is 5.80 meters, stepping down to a narrower 4.20-meter width at the top bay. (See attached sketch). * Roofing Cladding: 100mm Polyurethane insulated sandwich panels (Dead Load \(\approx 0.14 \text{ kN/m}^2\)). * Structural Hierarchy (Flush-Frame System): --Columns: Uniformly marked C1 (Low side, 2.70m) and C2 (High side, 2.80m) using SHS profiles. --Primary Rafters (R1/R2): Full-span RHS 200x100x4mm (or engineered equivalent). --Internal Purlins (P1/P2): Splitting the center spans, nested flush between primary rafters via welded side shear fins to keep a single, flat roof plane. * Internal Purlins (P1/P2): Splitting the center spans, nested flush between primary rafters via welded side shear fins to keep a single, flat roof plane. Preferred Software Stack: * Analysis: SkyCiv, Robot Structural Analysis, or SAP2000. * Drafting/BIM (Mandatory for hand-off): Autodesk Revit or AutoCAD. Information Needed from Freelancer in Proposal * Please confirm your estimated turnaround time. * Confirm that you can deliver editable native Revit/AutoCAD files. * Provide a brief example of a similar lightweight steel framing project you have engineered.

Flush-mounting the purlins inside the rafters instead of on top will drive the section choice more than the load case itself, since it caps usable depth on the primary members - do you have a target rafter depth or is that open for me to optimize? Also, is the 2-person lift limit per member (so no piece over roughly 25-30kg) or total assembled weight? I've done structural drawings and load calculations for aluminum framing in production settings, including spec sheets and fabrication drawings, so I can build the SHS/RHS model and calc report from your span and clearance requirements.
