For such an effort, screed rails were supported on scaffoldings which allowed the vertical installation of LVDT at the bridge mid-span, as observed in Figure 8 and 9.
Para ello se diseñaron cerchas apoyadas en andamios, que permitieron instalar en forma vertical los LVDT a la mitad de la luz del puente, como se observa en la Figura 8 y Figura 9.
