Chinese contracting firm Powerchina has commenced piling works for the foundation of the super-tall towers in Saudi Arabia’s SR1.9tn ($500bn) NEOM development. The package awarded to Powerchina entails the drilling of cast-in-place piles with diameters of 1.5 and 2.5 metres, fabrication and installation of steel cages, and concrete pouring, excavation and chiseling of pile heads, and inspection of cast-in-place piles.
The first towers at sea level on the coast will be 500 metres tall. The building heights will then decrease in direct correlation with the rise in topography, which means all the building roofs will be 500 metres above sea level. The ultimate plan is for the towers to continue for about 100km until the land reaches 500 metres above sea level.
