3_IDENTIFY & DESCRIBE STRUCTURAL MATERIALS 1. Concrete (precast and in situ) -  Blinding concrete -  Strip and pad footings -  Slab on ground (top and bottom) -  Bored pier -  Columns -  Suspended slabs -  Beams 2. Solid Pressed Bricks (reinforced) -  Walls 3. Steelwork -  Welding -  Bolting -  Connections -  Roof sheeting -  Corrosion protection (internal steelwork not exposed,

external steelwork exposed) 4. Timber -  Beams built into brickwork 5. Galv Steel Strap Bracing - Diagonal roof bracing

¡  C arbo n Fo ot p r in t §  Slight increase, (production of concrete

produces relatively lower amount of CO2) §  Concrete, bricks and steel are the main

materials used

¡  Em bod ie d Ene rg y §  Very slight increase §  More energy ef ficient in production of

materials

¡  Re cyc lab i l i t y

§  Higher possibil ity of recycling the materials used
