♦ Full span precast elements can be made under factory conditions that improve safety, precision and efficiency of works
♦ Besides work platforms at pier heads, only very little temporary structures are required on site
♦ The delivery of manufactured spans along the already made part of the bridge structure in no way disrupts the existing road traffic and no need terrain improvement works
