The latest figures reveal a steady increase in the value of construction in Tasmania over the past year.
The Bureau of Statistics figures show about $580 million worth of construction projects were finished in the final three months of 2012.
That is a 3 per cent increase on the previous quarter and more than 9 per cent higher than the same period a year earlier.
Michael Kerschbaum from the Master Builders Association says construction firms are benefiting from infrastructure projects.
"Power transmission, NBN cabling, those sorts of things coming into the figures," he said.
"That drives up the construction component overall, but I think that if you were to break that down further and look at the building side of it I think that you'd probably find that both resident and commercial have both been in decline for most of last year." Figures released earlier this month show the number of residential building approvals has been falling since the beginning of last year.
