Hilton Surfers Paradise Hotel & Residences is already making its mark on the Gold Coast skyline, with construction past half way on the first tower.

Workers have reached level 20 of Boulevard Tower, which will eventually stretch 32 storeys into the sky, and have completed four of the five basement levels.

The core structure will hit its full height in May, with the basement to be completed mid-year, ahead of total completion of the tower in late 2010.

At the same time, work is moving forward on the second and tallest tower, Orchid Tower, which is at level six and due for completion in late 2011.

More than 300 workers are on-site each day constructing Hilton Surfers Paradise Hotel & Residences, with that number expected to peak about mid-year, when up to 1000 workers will be involved directly and indirectly in the construction effort.
