Builder Fletcher Niven, who is also vice-president of the Orange City rugby club which has been hit by the fire, has won the tender to pull down and re-build the structure he built several years ago.

Mr Niven said he had mixed emotions.

"At first I was devastated," he said.

However Mr Niven said the grandstand would be rebuilt with a better layout than before the fire.

He said the original configuration of 80 raised seats and 80 at ground level would be replaced with a layout of 200 raised seats.

"It was never quite right," he said.

"We now have the opportunity to reconfigure the whole thing better."

Mr Niven said three of the grandstand's five sections would be removed because of structural and damage to the steel caused by the fire.

"Unfortunately we [have to] throw away all the steel work because of all the smoke damage," he said.

"It won't be ready for the start of the season."

Mr Niven said it was likely the structural work, and the provision of some seating, would be completed by the middle of the year.

He said the club would be seeking a grant through the state and federal governments and the Australian and NSW rugby governing bodies to pay for the completion of the project.

The club is also still seeking money through a GoFundMe account to pay for property and equipment destroyed in the fire that was not insured.

"The building as such was insured but the contents, all our set of goalpost and corner post pads, all our 22-metre markers have gone and melted, tables and chairs have gone and melted," he said.

Mr Niven said the junior rugby club had also lost playing kits in the blaze.

"That's $25,000 worth of material, there were three giant marquee tents there [too]," he said.

Mr Niven said the club had been heartened by the response of other rugby clubs.

The GoFundMe amount currently stands at $5236.

That includes $1500 donated by the Orange Emus Club.

Mr Niven said the Kinross Wolaroi rugby program had also donated $1000 outside of the GoFundMe account.

Fire crews raced to the scene about 2.15pm on Saturday, December 1, when the fire was first reported.

They extinguished the blaze before handing the site over to police as a crime scene.

Police forensic experts then combed the remains to search for evidence.
