THE cost of replacing the piles on the Urangan Pier has increased by $400,000 after the Fraser Coast Regional Council elected to use composite fibre piles instead of steel.
At Wednesday's council meeting in Hervey Bay, councillor for infrastructure and planning Trevor McDonald said it would be worth it.
Cr McDonald said using the composite material piles would increase strength and longevity.
He said using the composite piles instead of steel would extend the lifespan of the structure from 40 years to 100 years.
The Chronicle contacted the council for more information about the cost blow-out, but did not get a response before going to press.
In March, the council announced the $5 million upgrade to replace the wooden pylons with steel piles encased in a plastic sleeve and refurbishing 660m of the pier.
The contract was awarded to Sydney Marina Contracting, the same company that worked on the pier in 2009.
Work began in July and will be undertaken during daylight hours in winter during the next three years.
