Battling floods, difficult soils and the environmentally sensitive nature of the Amazon rainforest, crews are building a 3,600-meter-long, $400-million bridge with a 400-m-long cable-stayed central section over the Negro River using a 400-barge working platform. The project, marked by a death and environmental controversy, is intended to boost economic development in the Amazon. Brazil’s Manaus-Iranduba Bridge, scheduled for completion by year’s end, will straddle the river close to where the waterway merges with the Amazon River. The span will create a land link between the city of Manaus and the town of Iranduba as well as 30 other, smaller municipalities.
The market is generally healthy and steadily growing, and margins are up for large specialty contractors. Further, advances in design tools and owner demand for collaboration are giving subcontractors a seat at the table early on in projects.
