Tasmanian union leaders are concerned construction workers will leave the state if there are no more big projects.
The Brighton Bypass was Tasmania's biggest road project but now it is completed, many workers are worried about securing their next job.
The construction union says it is crucial major building jobs get started to prevent an exodus of skilled workers.
The CFMEU's Noel Washington says it is frustrating, considering there are major projects in the pipeline, including Hobart's Parliament Square and other stages of the Royal Hobart Hospital redevelopment.
"A significant number of our members are looking for work interstate," he said.
"I'm concerned that there are a number of projects now on the drawing board that don't seem to be getting started.
"That's very frustrating...from our members point of view who are waiting to take jobs up.
"It's encouraging that there is work to happen but it would be nice if some of it could get started." The Parliament Square project is set to begin within weeks, creating hundreds of construction jobs.
