Old Ways Burn
DESIGN, AND DEVELOPMENT. OUR WORK IS ALWAYS AT THE INTERSECTION
OF DESIGN AND TECHNOLOGY.
Why LEFF Makes a Difference
LEFF is not just another construction company—we are redefining how modern structures are built. Our difference lies in combining engineering excellence, advanced technology, and prefabrication expertise to deliver buildings that are safer, faster, and smarter.
Safety & Resilience – Our Cold-Formed Steel systems are non-combustible, mold- and termite-resistant, and engineered to withstand wind, seismic, and moisture challenges.
Precision & Technology – Using Revit, AGACAD, Tekla, and Navisworks, we deliver BIM-driven accuracy from design to installation. Every panel and connection is modeled, validated, and prefabricated to millimeter-level precision.
Speed & Efficiency – Prefabrication shortens timelines, reduces site waste, and eliminates costly rework. With LEFF’s EPC model, the entire process—from design to installation—is managed under one roof.
Architectural Freedom – Our systems enable long spans, large openings, and creative designs without compromising safety or performance—empowering architects and clients with true design flexibility.
Sustainability & Value – Built with recyclable steel and optimized processes, LEFF structures minimize environmental impact while delivering higher property value and long-term durability.
Choosing LEFF means choosing a smarter way to build. This is where engineering innovation meets structural reliability—and where your vision becomes a stronger reality.

Our
Services
- Design
- LEFF by using modern Technology and combining it with the latest achievements in the world, having its professional experts, and using creative designers, has been able to take a huge step towards achieving its short-term and long-term goals, which is to improve the quality of building industry and achieve uninterrupted performance level in project implementation. Therefore, with our precise design, we are able to deliver the right solutions for customers. Also, we manage to provide BIM as a prestigious way of delivering construction projects from concept design to in-site construction. With such service, the project can take various advantages, some of which are as follow: – Comprehensive building analysis – Clash detection (3D coordination) – Cost evaluation – Digital fabrication and forecast site issues – Supports Prefabrication and Off-Site Construction
- Permit
- In the end of design part, we prepare full designs packages to obtain Building Permit and pass city requirements.
- Shop drawing
- We produce highly detailed Structural Steel shop drawings that meet customer custom standards while adhering to guidelines set by CISC-ICCA (Canada) and AISC (USA).
- Fabrication
- One of the main missions of our company is that being able to use our specific Design-build method in order to provide Prefabrication and modular construction on projects to shorten the construction duration, reduce material wastage and costs, improve quality, and control labor costs. With Having a higher degree of detail earlier in the design phase we are able to prefabricate sections of the project becomes more viable. The BIM model is used to create shop drawings for prefabrication, and implemented as an information source in automated manufacturing processes that use digital machines. Therefore, based on the engineering drawings approved by the Client, our manufacture department is responsible to fabricate the structures according to the shop drawings in the factory. After CNC cutting and drilling, sections are formed and painted, and after passing the inspection control, they are ready to be transported and installed.
- Installation
- LEFF offer the whole solution for your project which are Design, Shop drawing, Fabrication and Installation to make sure we could achieve all goals in the below: – Efficient Design – Cost Saving – Time Saving – Harmony and Accuracy in Installation The Installation process: All panelized Load bearing walls are Installed with the crane in the jobsite. The Floor system is varied for each project, and it depends on Project character. Installation Category: – Installing all Columns and Main Beams – Installation the floor system – Installation Load bearing Walls – Installation Non-load bearing walls – Concrete slabs
