•Up to 30m [effectively 8-10 storey]
•Concrete or Steel cassette floors
•Range of off-site roof solutions

General scope of Metro Building SystemGeneral scope of Metro Building System
• Buildings up to 30m in height [Max 3.5m storey height]
• 10 storeys using steel cassette floors
• 8 storeys using concrete composite floors
• Most efficient solutions where load-bearing walls align vertically in a regular repetitive building
• Hybrid options with integrated hot-rolled steel components provide differentiation of floor plate layouts and longer spans/voids.
• Transfer deck solutions [podiums] facilitate radical floor plate span changes e.g. for ground floor retail space / undercroft car parks

Steel / Timber HybridConcrete Compartment Floors
Components of Metro Building SystemComponents of Metro Building System
• Ringbeam levelling interface to foundation
• Loadbearing structural wall frame units
• Floor and ceiling cassettes or concrete floors
• Compartment walls
• Internal non-loadbearing partition walls
• Roof structure and truss systems
• Components for integration of staircases, lift shafts shafts, balconies, brise soleil etc
• Components for integration of staircases, lift shafts, balconies, brise soleil etc
• Openings, penetrations for windows, doors, louvres, etc
• Building Services integration and routing
• External facades and roof envelope solutions
• Hot-rolled sections to accommodate: high point loads, over large openings and balcony and brise -soleil supports
The system includes:

Scope: Limitations on Metro systemScope: Limitations on Metro system
• Predominately open plan wide grid structures e.g. offices
[better constructed in hot rolled frame with cold rolled infill]
• Large and / or irregular clear span areas with high imposed loads e.g. Retail / Conference / Car Park floor plans
• Vertical support of masonry cladding – localised areas can be supported e.g. Gables in stepped terraces
• Discontinuous load paths require hybrid solution
• Cantilevered structures - modest balcony structures can be supported often in combination with tie rods or posts
• Significant relocation or demolition of load-bearing walls once complete without retro-fit steel support structures – knock-out panels for future Lifetime Homes provision [lift/hoist etc] can be easily detailed in

• Wide range of stud sizes allows optimisation of steel usage
• V-bracket riveted centrally in load-bearing studs and bolted for positive mechanical connection self-clamping to allow automation
• 4mm gauge 100mm wide Jumbo studs for tall structures/wide fenestration
• Over-bent track to ensure full bearing is achieved between stud and track
= High load capability allows tall structures and longer spans= Negligible vertical settlement in building lifespan= Full compliance with disproportionate collapse requirements

• All projects fully modelled in parametric software including ALL hot-rolled elements for full integration and peace of mind

Floor types and spansFloor types and spans
Site installed concrete composite Multideck floors:
• Asymmetric channel factory fitted to wall frames
• Asymmetric channel supports Multideck floor
• Floor spans generally most efficient up to 6m
• New Kingspan Multideck 146 allows long span floors up to 6.45m with 215mm deep floors
• Allows open plan apartment solutions with up to 9.15m spans for 305mm deep floors

Floor types and spansFloor types and spans
Factory assembled steel cassettes with ledger angles:
• Ledger angles on cassette edges provide temporary support and level guide on site
• Cassettes bolted to sides of stud walls
• Spans up to 8m for 300mm joists
• Spans up to 6.5m for 200mm deep joists
• Safedek / Caberdek factory fitted

Roof integrationRoof integration
Four main options:
• Timber trusses• Steel purlin / cassette [room in roof option]• Lattice trusses for barrel vaults etc.• Kingspan Topdek Offsite solution for early weather protection
• Green and Brown roofs can be accommodated
• Roof coverings accommodated:• Top-dek / Single Ply membrane• Standing Seam• Traditional tile slate / concrete / clay
• Sloping roof cassettes in Metro system eliminate cost of tapered insulation on shallow pitch roofs

Foundation OptionsFoundation Options
Metro compatible with range of foundation solutions:
• Podium deck• Raft• Strip foundations• Screw piles and Vibro-ground improvement
• Certified foundation details have been thermally modelled to assess thermal bridging and condensation build up
