Emaar have already appointed a contractor to carry out clean up and refurbishment. DUTCO. The local arm of Balfour Beatty from UK, who also have an in house MEP organisation BK Gulf. Seems Dutco will appoint a consultant to oversee the works. DUTCO built the adjacent Dubai Mall and are now extending that.
The original contractor(s) of The Address were Besix (from Belgium) when the place was first built. More info here

Presumably the damaged cladding must be replaced with new fire-resistant / fire-retardant panels and the undamaged part of the tower (maybe around 85% of the total) will also be upgraded to match? That won't be cheap.
