Extra Space Steel Framed Six Storey Volumetric Building System

The design represents a primary hot rolled steel frame with light gauge steel framed elements forming floor, roof and external wall cassettes.

Durability Assessment: Minimum of 60 years

Limits of Scope

• Maximum 6 storeys subject to scheme specific structural analysis.
• Bottom members in contact with foundations/sub-structure must be fully isolated from contact with moisture from the ground or external sources. The LGSF must not be at risk of exposure to any moisture source.
• Masonry wall cladding cavities should be minimum 50mm width and ventilated.
• Conventional cladding systems should have a drained and ventilated back- cavity, or as required by the cladding manufacturer (minimum 25mm);
• Rendered external thermal insulation systems and/or insulated brick slip cladding systems applied to steel-framed structures must have a minimum 15mm drained back-cavity. Detailing should be considered to minimise the risk of water entering the structure at vulnerable junctions, for example flashing arrangements at window jamb/sill junctions
• Adequate sub-floor ventilation must be maintained to the void below the ground floor (min. 1500mm2/m or 500mm2/m2 of floor area).
• The ground below the floor must be sealed with a membrane to prevent moisture entering the void (e.g., polythene membrane + 50mm gravel ballast)
• Extraspace Solutions must be contracted for the design, manufacture, supply and erection of the structures.
• A chartered structural engineer suitably experienced in the design of this type of structure must carry out the structural analysis and design.
