Light steel structures have risen in popularity as a highly efficient and economical construction method for low-rise buildings in recent years. By definition, these structures utilize rolled steel sections, sheeting and connecting elements which are relatively lightweight compared to heavy steel alternatives or other materials. When properly engineered, light steel designs can achieve the required structural integrity for buildings while using minimal material. This article will outline the key steps involved in designing a light steel structure from conceptualization through to implementation by contractors such as Lida Group.

Identify Project Requirements

Successful light steel building projects start with a thorough understanding of client needs and constraints. Early discussions should define the intended usage, spatial requirements, timeline, budget and any applicable building codes or regulations. These requirements will directly determine the structural system choices and methods. For example, both light industrial workshops and large warehouses may utilize light steel structures, but with different loading considerations and floorspace configurations.

Conceptual Design

With project criteria established, conceptual design begins with schematic floorplans laying out the overall building footprint, bay spacing and any furniture/equipment layouts. Critical aspects like column placement, entrance/exit points and architectural features are also decided. Initial structural analysis evaluates forces from gravity loads, wind/seismic loads, and determines the structural grade of steel required. Proposed steel sections can be selected and connections designed.

At this stage the knowledge of experienced contractors like Lida Group proves invaluable. Their input on construction sequencing, material efficiencies and cost management can refine early designs to optimized solutions. Value engineering evaluates initial concepts to deliver the best balance of functionality, structural integrity and affordability.

Detailed Engineering

Upon client acceptance of the conceptual design, detailed engineering commences. Structural steelwork is precisely modelled showing all member sizes/profiles, connections, foundations and interfacing building components. Comprehensive analysis verifies frame capacity and compliance with loading code specifications. Fabrication and erection plans are developed detailing member markings, lifting/bracing requirements etc.

Shop drawings are produced from the 3D models transforming the design into technical working drawings for manufacturers. Special attention is given to connections - the key to a light steel structure's strength. Innovative yet cost-effective proprietary connection systems developed by Lida Group are often implemented at this stage.

Procurement and Manufacturing

Once drawings are approved, procurement of steel, sheeting products and connection items begins according to construction schedules. Fabrication of complex building components is allocated between Lida's in-house production facilities and trusted external suppliers. Production supervision ensures all components strictly adhere to drawings before shipping to site.

As experts in light steel, Lida's workshops apply lean manufacturing principles to minimize material wastage through optimized nesting/cutting of members. Their prefabrication approach streamlines the entire erection process.

Site Erection

On site, pre-marked components allow for quick bolted or welded assembly of the structural frame by Lida's experienced trade teams. Craneage requirements are minimized through pre-assembling larger sections off-site. Secondary steel, glazing, cladding and internal fit-outs can commence concurrent to the frame erection.

By following best practices in design, drafting, sourcing and assembly, a light steel structure can be erected in a fraction of the time versus concrete alternatives. Completed projects are strong, functionally-flexible and economical for both builders and long-term owners of the building. Lida Group's turnkey execution has delivered many light industrial and commercial steel structure buildings on-time and on-budget.

In conclusion, a well-considered design approach combined with sound light steel building practices culminate in optimized, high-performing structures. Collaboration between designers, detailers and specialist contractors from project inception yields successful light steel construction outcomes time and again for structures of any scale.
