Patrons continued to sip their coffee in the cafe under the empty seven-storey Sky Park in Phillip on Tuesday afternoon as right next door, structural engineers were attempting to determine the cause of a major retaining wall failure at a huge Geocon development site on the weekend.

While the engineering analysis continues, property developer Geocon is not prepared to offer any comment as to the possible cause of the collapse, which occurred around 2.30pm on Saturday.
