Design & Engineering
From architectural vision to structural certainty.
Design & Engineering
At LEFF, design and engineering are not isolated steps—they are the backbone of our entire execution process. We transform architectural intent into coordinated, code-compliant, and constructible systems by combining decades of engineering expertise with the most advanced digital tools available.
BIM-Driven Structural Design
Revit + AGACAD Automation: We develop Cold-Formed Steel (CFS) framing models from schematic layouts to LOD 300–400 detail, automating panelization, stud spacing, headers, jambs, and bracing with AGACAD.
Rhino Geometry Integration: Complex geometries and free-form façades are rationalized and exchanged back into Revit, ensuring architectural vision is never compromised.
Parametric Data: Every wall, joist, and connection carries metadata for fire rating, acoustic performance, structural load paths, and sequencing. This ensures one single source of truth from design to fabrication.
Engineering Analysis & Code Compliance
Structural Simulation: Load paths for dead, live, wind, and seismic forces are calculated and validated.
Tekla & Navisworks: Used for connection detailing, tolerance analysis, and clash detection with ARC/MEP systems.
OBC/NBC Conformance: All systems designed to meet or exceed Ontario and National Building Code requirements, with documented calculation packages for AHJ review.
Visualization & Communication
3ds Max + Lumion: Realistic renderings of structural layouts for quick stakeholder approvals.
Unreal Engine VR: True-to-scale immersive walkthroughs, allowing architects and clients to experience the structure before it’s built.
AutoCAD Outputs: Clear 2D sections, elevations, and detail sheets extracted from the BIM model for rapid reviews and permit submissions.
Deliverables
Coordinated BIM models (.rvt, .ifc, .nwc/.nwd)
Structural calculation reports and compliance documents
Permit-ready drawing sets (stamped and sealed)
Shop drawing-ready LOD 400 models for fabrication
Visualization packs (renders, VR scenes, animations)
Design and engineering at LEFF is where vision meets precision.
Every decision, every joint, and every panel is modeled, analyzed, and validated—before fabrication begins—ensuring the end result is safe, efficient, and faithful to the original design.
