Construction—South America—Brazil—Bridges
The beams were produced in a factory on
the job site, and 5 Type 12-0.5" DSI Prepron
Strand Post-Tensioning Tendons were
installed in each segment. The strand tendons
that were inserted in ducts were stressed
using a jack supplied by DSI Prepron.
Due to the very limited time frame, DSI Prepron
and Acciona planned all the steps necessary
for a faster construction progress.
Thanks to the optimized workflow,
DSI Prepron successfully carried out the
complete stressing and grouting work
on the tendons of the 70, 40m long
prefabricated beams in only 3 weeks.
Work at this major project has not yet
been finished, and DSI Prepron continues
to support Acciona with high-quality
products and technical know-how.
