As announced earlier, work on the Kingdom Tower started in January. Thanks to Naif Saudi from Skyscrapercity forums, we can now see some movement on the site of the tower.
On the first picture we can see some construction equipments in the background. Although it is not 100% clear from the image alone, but one of these equipments resembles a pilling rig.
Although there isn’t much movement on the construction site as of yet, the fact that machines were deployed to the site on January 2012, as previously announced, is a major step forward for the Kingdom Tower project.
