The new pavilion will have attractions such as a twin-chute helter-skelter
Work to rebuild the fire-ravaged pavilion on Weston's Grand Pier will get under way later.
About 70 piles will be driven 30m (32.8yds) into the bedrock providing support for the new structure.
The piles will be forced into the sea bed from a barge which can be jacked up and down on legs depending on the tides providing a stable work platform.
The work is scheduled to last up to 15 weeks. The new pavilion is intended to reopen in time for summer 2010.
Kerry Michael, owner of the pier, said: "The beginning of the piling work is great news and is the beginning of the reconstruction of the pier following the fire.
"We're keen to get the work under way and it means we are on schedule to reopen for the summer of 2010.
"We aim to keep disruption to local people and businesses to a minimum during this work and we can now look forward with heightened anticipation as the new Grand Pier starts to take shape."
The new pavilion will include a selection of attractions including an 85m (92.9yd) panoramic tower that will rise up and revolve 360 degrees, a roof-height twin-chute helter-skelter in the north west tower and an Edwardian tea room.
"We still have a very long way to go but we are determined to achieve our goals and provide the town with a world-class facility in time for the summer season 2010," said Mr Michael.
