Structure Kingspan Metro Building System 2

Overview Scope of the Metro system • General scope of Metro framing • Load-bearing capability • Floor types and spans • Roof integration • Foundation options 3

General scope of Metro Building System • Up to 30 m [effectively 8 -10 storey] • Concrete or Steel cassette floors • Range of off-site roof solutions • Suitable: Ø residential Ø student accommodation Ø health & education 4 Concrete Compartment Floors Steel / Timber Hybrid

General scope of Metro Building System • Buildings up to 30 m in height [Max 3. 5 m 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 5

Components of Metro Building System The system includes: 6 • 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, 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 Concrete Compartment Floors Steel / Timber Hybrid

Scope: Limitations on Metro system 7 • 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

Kingspan Metro Building System Typical Examples Felstead Street, London Glassford Street, Glasgow Falkirk Block, Newcastle 8

Load-bearing capability • 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 • 4 mm gauge 100 mm 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 9

Load-bearing capability • All projects fully modelled in parametric software including ALL hot-rolled elements for full integration and peace of mind 10

Floor 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 6 m • New Kingspan Multideck 146 allows long span floors up to 6. 45 m with 215 mm deep floors • Allows open plan apartment solutions with up to 9. 15 m spans for 305 mm deep floors 11

Floor 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 8 m for 300 mm joists • Spans up to 6. 5 m for 200 mm deep joists • Safedek / Caberdek factory fitted 14

Roof integration Four main options: 17 • • 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 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 18
