In March last year, a conservation team used 3D technology to scan the artworks and create a digital model so they can be reprinted in the future.
However, Angela Greenfield from the civic society said: “We’re hoping some of the sculptures will be saved. 3D scans don’t cut it. They’re a scan, not the piece of art.”
She said: “We’re not optimistic any real effort is going to be made and that is completely wrong.
“They’re important and Harold Gosney is a renowned sculptor. He’s celebrated in every other part of the country and yet in Grimsby that he’s connected to we just dispose of his artwork.”
A council spokesperson said: “At a meeting with Harold Gosney last year, the artist confirmed the panels were cast in situ with metal bars running through them which were integral to the car park structure, which is likely to make removal of the artwork incredibly difficult.
“Since last year, we have digitally preserved the artworks, 3D scanning and taking high quality pictures of the artwork on the ground floor too.
“Once work has started, the contractors will be able to investigate whether or not some of the original artwork can be saved.”
The council said demolition work was expected to take 12 weeks to complete.
