Construction of the cast in place concrete connection between the ends of two precast reinforced concrete beams. This connection will make them a single reinforced concrete beam, which will then be post-tensioned to become the tension tie beam that carries the outward thrust of the cantilevered arches of a V-shaped bridge pier. The beam ends and this construction point are supported from the ground by a steel truss scaffold erection tower, of which we see only the top part. Wood forms will be built around the bottom and sides of the space between the two beams, into which ready-mix concrete will be placed. After this concrete has gained its strength, post-tensioning cables run through tubes the length of the two beams will be tensioned to create the post-tensioned tie beam.
