A barge-mounted Manitowoc Model 1015 duty-cycle crawler crane is creating drilled shaft foundations on a replacement bridge project in Brunswick, Georgia, US, as part of road improvement work on Interstate 95. It is working for Coastal Caisson, a subsidiary of geotechnical engineering company Bauer.

“On this job we needed a crane that would give us the extra reach from the barge to the pile positions that our traditional foundation equipment doesn't provide. When we looked at what was available, the 1015 was the ideal choice,” said a Manitowoc spokesman.

The job includes more than 420 piles with diameters of 1.4 and 1.5 m, installed to depths of up to 46 m. The 1015 is working with 32 m of main boom, with a Bauer B 36 attachment to drill the caissons. It started work in February and is due to leave the site in mid-2008.
