Months of meticulous work has gone into the creation of a 400-metre synthetic athletics track, which together with a new 600-seat grandstand, could lure significant championships to the city.

Dubbo City Council has been determined its Barden Park Centre of Excellence for Athletics will meet international standards.

Contractor David Payne Constructions has shared the commitment in redeveloping the humble oval that will soon cater for pole vault and other new disciplines as well as long-time favourites.

The progress of the project, which the contractor estimated had provided about $1.5 million in wages and of its sub-contractors, 90 per cent were local businesses, was on display to media on Wednesday ahead of a public open day on Saturday.

Council parks and landcare services director Murray Wood spoke enthusiastically about the redevelopment - funded by three tiers of government - on Wednesday.

The quest for the seal of approval from the International Association of Athletics Federation, the sport's governing body, included engaging a Bangkok-based company to complete the track's linemarking, one of only about three in the world certified to do the work to standard.

"Nowhere else in the central west has that certification," Mr Wood said.

"It's exciting - this will be fair dinkum international standard.

"If someone sets a record here, we want it to be counted."

The council has been pursuing hosting rights for future NSW Country Championships.

The director said Barden Park would be flexible.

The ground floor of its grandstand could provide low-cost accommodation to sporting groups from outside Dubbo, underlining that Barden Park would be a regional facility, Mr Wood said.

When not in use for its priority - athletics - it could host development camps for other sports, he said.

"We want to get as much use as possible out of this," he said.

The revenue policy would reflect that potential hirers would host events of varying scales from school sports carnivals to "high-end events".

"We've tried to make it flexible," Mr Wood said.

The walls and roof of the grandstand are now being lined, seating installed and the canteen nearing completion ahead of handover in mid to late September.

The location of the track is visible, with the asphalt foundation in place ready for the synthetic track to be laid once warm enough in mid-September, in a three-week process.

Mr Wood said all residents interested in attending Saturday's open day must book in for a tour by calling the council's customer service centre on 6801 4000, with tours scheduled to run every half hour between 11am and 1.30pm.
