After a photographic report issued by the National Institute of Roads, Inbias, on the bridge of Hissagura, citizens and authorities began to doubt the stability and security that this ambitious work could provide.
Due to the above, supervision of the Chamber of Commerce of Bucaramanga, CCB, was transferred to the site, on the road Curos-Málaga do a test on the ground.
Juan Carlos Rincón Liévano, vice president of regional investment development for the CCB, told Vanguardia Liberal that during the tour, which was done with two engineers, "it is actually observed that when the bridge is closed, multiple questions are asked. , And here comes the big question, what should be done at this time to give peace of mind. "
According to Rincón Liévano, engineers concluded that, although there are no cracks or repairs on the bridge, it is worrying how the structure is observed on the sides. That is, with the prevalence that was actually appreciated in the report of Invías.
For this reason, the vice president of regional investment development of CCB, estimated that the national government should be required to take immediate action to order structural criticism. The idea is to satisfactorily accept this kind of work. We can not ignore the significant investment made, were 100 billion pesos, and therefore deserve to be transferred under the best conditions.
In addition, Rincón Liévano said that they will ask for information to see what happens with the load tests that so far they have not been made and it has been more than two months since the managers completed the construction work.
Today it is expected that members of the inspection and representatives of the CCB make the request and the concerns encountered during the visit to the national government.
Interventoría talked about prevalence
The Liberian Vanguard tried to communicate several times with the ETA, in charge of the intervor of Hisgaura Bridge, to obtain more detailed information on the frequency that occurred. Although they did not answer calls, in an interview radial experts explained that these sinusitis are normal and occur in bridges and cable remains as Hisgaura. "It is acceptable in this type of structure because of the flexibility of these bridges.In each stage the geometry of the board changes and it is really known at the end when it is closed in the center and the cables are retensed," said Samuel Montreau, ETA's review expert. He added that "engineers will realize that modulus of flexibility of the concrete varies greatly, such factors as the temperature of cables and others, because the calculations do not go as planned."
