The facility is being built at Bucksburn by the council, along with partner Henry Boot Developments and main contractor the Robertson Group.
Last month, two specialised cranes lifted the 88-metre long, 84-tonne steel beams spanning the width of the main arena into place. Work is also underway on an Energy Centre that will provide power, heat, and cooling to the new venue.
Once completed in 2019, the new exhibition and conference centre is expected to attract major artists and events to the city.
Council Leader Jenny Laing said: "Work at the site of the £333million new AECC is continuing at a great pace and it shows what a significant development this is for Aberdeen.
"With the delivery of the main beams last month and along with the foundations being laid for the energy centre, I'm delighted to see the progress at the site.
"We are confident that the scale and quality of the new AECC will ensure it competes with the best national and international venues and it will play an important role in helping to grow our local economy."
Nick Harris, Scottish Director at Henry Boot Developments said: "It's amazing to think that in two years' time, this fantastic new facility for Aberdeen and the north-east should be open.
"Work is continuing to go really well on site and remains on schedule. In particular, the main beams for the new arena that were lifted into place recently really begin to give an idea of the impressive scale of this project."
