âIt was difficult for usâ: Libermans move on after Grollo stoush Weâre sorry, this service is currently unavailable. Please try again later. Dismiss Save Normal text size Advertisement A prominent member of the ultra-wealthy Liberman family says it is too early to say whether they will work again with the Grollo family after a major fallout between the two high-profile Melbourne dynasties. Large parts of Grocon collapsed in November last year with 45 companies put into administration and one of the casualties was Libermanâs $111 million office construction project in Melbourneâs Collingwood. Liberman family members acquired the office block in 2017 through a trust managed by ethical investment fund the Impact Investment Group (IIG), which is owned by Berry Liberman and her husband Danny Almagor. The fund tore up its contract with Grocon in December. Liberman has now resumed work on the office tower with building giant Probuild brought in to replace Grocon with the project delayed by about a year.
