"
2018
Kingdom Holding Company signed a deal with Orange Business Services to provide information and communication technology (ICT) infrastructure to Jeddah Tower. Construction of the tower moved forward after a short delay.
There was steady progress but building owner JEC halted structural concrete work with the tower about one-third completed due to labor issues with a contractor following the 2017–19 Saudi Arabian purge. JEC said they plan to restart construction in 2020.
2020
Resumption of construction works was made impossible by the Covid-19 pandemic."
