Innovative Offsite Housing Systems One of the main advantages of light steel framing for residential projects is its versatility and the range of building types for which it can be used. Applications for LSF systems range from low-rise housing to multi-storey, multi-occupancy developments. The wide range of applications is in addition to the associated benefits of modern offsite methods of construction: rapid speed of build, high quality and performance, excellent safety and cost-effectiveness.
KEY BENEFITS
Advantages to the Construction Industry
• A packaged construction system in which all structural components are designed, delivered and installed by one supplier
Light steel framing systems augment the construction industry with a broad spectrum of benefits from offering predictability of costs and programme to reducing risk and enhancing building safety. The versatility of steel offers architects the freedom to achieve their most ambitious visions. Building owners value its adaptability and the benefits that steel framing solutions provide, such as the light open and airy spaces which are ideal for reconfiguring or extending with minimal disruption.
• Offsite manufacture minimises on-site deliveries. A house can be constructed from as little as 12 wall panels and up to four houses or large apartments can be delivered per lorry. • ‘Just in time’ delivery protocols reduce the need for on-site storage • LSF reduces loading on the foundations and any supporting structure • High-quality in terms of geometrical accuracy and freedom from any long-term movements due to creep and shrinkage • Good sustainability rating based on a range of environmental criteria. LSF systems can be designed for low U-values and scores A+ or A under the BRE Green Guide. • All steel components can be reused or recycled • Building extensions can be made easily to meet future requirements • Integrated BIM models are used by all construction partners
But to maximise the advantages of using LSF systems these considerations must be factored into the construction process: • Identify that LSF will be used at concept stage, and do not change track once detailed design commences • Engage early with the system manufacturers engineers and technical team • Ensure layouts wherever possible allow efficient transfer of loads from the roof to substructure • Determine if any additional elements are to be incorporated which will impose loads on the LSF structure.
