Developer Jody Gosling told the Central Western Daily she was already fielding calls.

“I’ve had a lot of local contractors contact me and I’ve been getting back in touch with all of them,” she said.

“Handymen, electricians, plumbers, which will be needed.”

Ms Gosling, a director of Queensland-based Verde Property, said they would be seeking many local contractors for the work on the $70 million three-storey building which will become the new home of the DPI in Orange in late 2020.

She said they were looking at starting work on the Prince Street site in December or at the start of February next year.

Ms Gosling said Verde Property was committed to a long relationship with Orange.

“We are in Orange to stay,” she said.

Ms Gosling said remediation work would ensure they had a “clean site” to work with.

Orange City Council spokesman Nick Redmond said final demolition clean up work started this week and should be completed by mid-August.

“Large piles of dirt were removed and disposed of appropriately,” he said.

“The final stages were waiting on an assessment of the waste material to determine how best to dispose of it.”

He said dust suppression water sprays were used and asbestos specialist consultants were on site this week.

Mr Redmond said the site would be levelled, grass seed planted, a retaining wall would stay to protect trees and the fence would be repaired and kept on site.
