They posted the "official" updates just before xmas at :
http://novacentre.ca/construction-updates/december-2015
GENERAL UPDATE:
95% of the structure is complete at this point and now sits 283 feet above Argyle Street.
To date, roughly 40,000 cubic metres of concrete have been poured.
184 sections of building glass and 17 pieces of the ‘blue box’ glazing have been installed.
The deck over the ballroom is nearly complete with roofing schedules to start in the new year.
The main structure of the convention centre is almost complete.
Installation of the aluminum framing for the levels below L3 is underway.
Installation of the curtain wall system is underway up to level 8. The installation will now begin to ‘corkscrew’ around the building on two elevations.
Nova Centre is only the second project in Atlantic Canada using a unitized glazing system. The unitized system reduces a significant amount of on-site labour and helps to enclose the building faster by installing prefabricated glass and frame units, which are lifted into position using a crane.
WHAT’S COMING UP IN DECEMBER:
The installation of elevators and escalators will continue.
Installation of the ‘blue box’ glazing is underway and the face of Argyle will be completed before the end of December.
Interior framing will begin in both the convention centre as well as the cores.
