Structural Fabrication Design for Pitched Tile Roof (BMI Monier Elabana)
Budget: ₹1,500 – ₹12,500 INR
Project Overview: I am looking for a structural designer to provide a fabrication-ready drawing package for a terrace roof covering. The structure will be supported by existing RCC columns and must be designed for BMI Monier Elabana Concrete Tiles (approx. 41kg/m²).
Technical Specifications (Mandatory):
Roof Type: Multi-sloped / Multi-hipped.
Preferred Pitch: 22 Degrees (for aesthetics and monsoon drainage).
Columns: 6" x 6" SHS (Square Hollow Section).
Trusses: 2.5" x 5" RHS (Rectangular Hollow Section).
Rafters: 2" x 4" RHS.
Battens/Purlins: 1" x 1" SHS (Critical: Spacing must be exactly as per Monier technical specs, approx. 330mm–345mm C/C).
Required Deliverables (The Package):
General Arrangement (GA) Drawings: Plan, Elevations, and Sections showing clear center-to-center dimensions for all columns and rafters.
Batten Layout Plan: A precise mapping of the 1"x1" battens to ensure the concrete tiles lock perfectly.
Hatch & OTS Framing: Detailed structural framing for a 2ft x 4ft (600x1200mm) Hydraulic Access Hatch and a separate OTS (Open-to-Sky) terracotta/glass section.
Connection Layout: Basic shop-drawing level details showing how members meet (Miter cuts, overlap, and base plate positioning on RCC columns).
Material Summary Table: A simplified table listing total linear meters of each steel section and total count of Main Tiles, Ridges, and Hips.
Contractor Requirements:
Must provide a 3D wireframe or 3D model for geometry confirmation before finalizing 2D drawings.
Experience with pitched roof systems and heavy tile loads is essential.
Ability to work from PDF/Image architectural plans (no CAD file provided).
Budget & Timeline:
Budget: ₹12,500 (Fixed).
Timeline: 3–5 Days for first draft.
