  2. Pile FoundationsProfessor Chris Gorse and Ian Dickinson These slides should be read in conjunction with Emmitt, S. and Gorse, C. (2010) Barry’s Advanced Construction of Buildings. Oxford, Blackwell Publishing

  3. Pile foundations Ground beam Piles Pile foundations. The pile foundation takes the load of the building through made-up ground or weak soil to load bearing strata. Ground beams transfer the building loads to the piles.

  4. Precast driven concrete piles Pile foundations. Columns of concrete driven into the ground by a percussion hammer

  5. Cable percussive auger. Piles can be bored to considerable depths

  6. Auger bored piles Pile foundations. Threaded cutting rigs cut through the ground boring a hole (column) which is replaced with concrete or reinforced concrete.

  7. Ground beams Piles Steel piles inserted – where ground beam reinforcement is positioned the steel piles have been trimmed so that they sit below the beam

  8. Reinforcement used to create ground beams to span between piles and carry the building loads.

  9. This ground beam is sitting on top of piles.

  10. Cardboard formwork used to contain the concrete within the ground beam and prevent excessive use of concrete. Concrete outside the designed foundation area would be wasted and add additional weight to the building.

  11. Ground beam Steel reinforcement cage for ground beam Excavation for pile cap or pad foundation Partially complete ground beam spanning onto pile cap
