Application:    
Laguna Bridge consist of 1000 meters elevated road, including 105 meters over the Pinheiros river. The conforming project design had 2 temporary columns in the river. The redesign to construct the bridge with cantilever method saved 30% of the budget. The road beside the river was constructed over running traffic. The solution was to use scaffolding systems to construct the bridge over the 4 lanes of road. The SAS thread bar system was used to tie down and secure the weight of the scaffolding system and temporary steel structures.
