The reason for all the scaffolding and bracing is to support the outward thrust of the diagonals. They need to provide that temporary support until the top side of the triangle is fully poured and cured - could be 3-4 weeks for a full cure.
I'm interested to see how they reinforce the top side of the triangle - lots of tension load there so I expect it to be pretty dense with rebar.
