This pulp mill expansion project was built as a floating structure, since it has a series of underground tunnels interconnected by openings, commonly called manholes. These structures have an interior slope and a water stop on all their exterior walls in order to decant liquid. They serve as foundations for huge silos. Due to its circular shape, this type of structures represents a significant challenge when it comes to accommodating rebar vs. anchorages. The meshing of foundations of these characteristics are developed orthogonally with bars of Ø6 and Ø2 while the anchors of the silos are arranged circularly - and for each anchor, a confined pedestal is developed which ends up being a large circular wall. Furthermore, all the interior walls must support the high loads of the silos. The team utilized Dowco.s workflow and expertise in order to deliver the project effectively in close collaboration with the client and their specific requirements.
