Construction company Dubbo Terrazzo and Concrete Industries anticipates up to 150 tradespeople, including a strong turnout of locals, will work on development to bring it to completion by the end of next year.

Plans for the 70-bed aged care facility within the Dubbo Masonic Village site located in the Keswick Estate were approved in February.

Dubbo Terrazzo signed on as the builder at the end of June and earthworks and civil works at the property in the Keswick Estate area moved ahead in recent weeks.

A fall of rain last week temporarily stopped the action that had been visible from Cobra Street, but in less than a week the crews were back at work.

Dubbo Terrazzo project manager Warrick Wheeler said they had done the first concrete pour.

With the concreters being from Narromine and a Dubbo business supplying the concrete pump, the stage was an example of what the construction project has to offer the Dubbo economy.

Mr Wheeler said the job would require a total workforce of up to 150 people and that by last week about 40 people had been inducted on site.

It is likely to be a hive of activity during some stages of construction, with "about 80 people on site at any one time".

A local electrician, plumber, roofer, concreters and air-conditioning business were being used and all the frames were being made locally, Mr Wheeler reported.

"And we're local as well," he said.

"It's a good opportunity to build an asset for the city."

Once the pour was done and cured they would start on the frames. "You should start to see some frames go up towards the end of September," Mr Wheeler said.

Dubbo Masonic Village support committee chairman Leon Burke said the laying of a foundation stone on July 30 had been momentous for the group, which had been working towards gaining the facility for about 20 years.
