557 7.6 Installation on site Despite the initial delay, the mechanical phase concluded in December 2024, reducing the execution period from 145 to 90 days. The assembly of a modular station was completed in 20 days with eight operators, allowing the electrical and transport installation to be moved forward, as visualized in Figure 8. No dimensional deviations were recorded in principal structures, validating the precision of the modular design; field adjustments were limited to secondary protection elements. Figure 8 - Assembly of two modules of the last station A strategic review compressed the final installation window by 38%, from 109 to 68 days. The methodology was restructured by consolidating the stations as integral units in the pre-modularization area, moving the macro-structures with their skid chassis using self-propelled modular transporters to their final location, as visualized in Figure 9. Figure 9 - Transport of assembled station to the installation site To optimize leveling without deep foundations, a layer of lean concrete was applied, facilitating the chassis-ground interface and accelerating stabilization. The assembly of the three lines was completed in 56 days, allowing for no-load tests and automation integration before the start of operations in June 2025.
