Due to the logistic constraints and limited head room allowances, micro piles were envisaged for the captioned project, I.e.,The Supply, Installation, Testing & Commissioning of Gas Insulated Line (GIL) Between 400 KV GIS at DREP and Step up Transformer at K-III and Associated Modification Works in Jebel Ali.
Methodology
Drilling was performed by Swissboring by rotary drilling methods using bio-degradable polymer mud as the flushing medium.
Since there were limitation head room tolerance small drill rigs were employed for the construction of micro piles.
