Henry Boot Developments Ltd was selected by councillors as the preferred bidder for the new Aberdeen Exhibition and Conference Centre project in November 2013.
The company taking forward the proposals for the site at Bucksburn has held a series of consultation events to allow the public to view the ambitious plans.
The main arena of the venue would house up to 15,000 people standing, while there would be enhanced conference space and a four-star 200-bedroom hotel.
A “green energy” centre which would generate enough power for the new AECC and potentially, the wider area, is also planned.
Chief among the issues raised by members of the public were traffic congestion in the Dyce and Bucksburn area.
Nick Harris, regional manager for Henry Boot, said the company was “acutely aware” of the roads issues around an “almost unprecedented level of development” in the airport area.
He said council officials were working on a “holistic” study of the road network, which takes into account all of the proposed schemes, including the AECC and two new business parks.
However, it has been the finances and the long-term running cost of the operation that has caused the most concern among local politicians.
Members of the ruling Labour-led coalition have clashed repeatedly with opposition SNP and Liberal Democrat members.
The SNP said at the time the deal was first agreed that there was no business case for the scheme, and warned the taxpayer could potentially be left to foot a large bill.
The administration had previously announced it was writing off a debt in the region of £26million that had been run up at the existing Bridge of Don site.
The council is understood to be considering bringing in a private sector partner to run the new facility, if it goes ahead.
Henry Boot Developments has so far declined to comment on recent reports on the AECC.
