I doubt it has anything to do with construction. It's being built in the wrong spot. Any parades around the corner as it look almost like the base for temporary stands. They could also be building fly forms for a neighbouring construction site.
They also don't need hoarding to excavate. They do need shoring rigs, excavators, concrete and steel. I'll wait until that is parked on site before I get a little excited. I'll still hold off until the tower is at least topped out considering the parent company is in and out of bankruptcy protection with over a dozen stumps between Almaty and Astana. Gotta feel for R Varacalli.
