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

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
