Sacyr canceled the cargo test on Hisgo, after agreement Local

The stress test on the Hisgaura bridge on the Curos-Málaga road, which was scheduled for Tuesday, November 20, was canceled by the construction company Sacyr.

The decision was made after submitting an application for ETA control to postpone the deadline to draw up one road map for the last phase of the work.

As it turned out, after the meeting, the National Road Institute, Invías, Adaptation Fund, construction company Sacyr and Interventoría expressed their readiness to develop the stages proposed by the Fund and Invías, which provide a comprehensive review and analysis to the load test report and protocol in such a way to measure actual bridge capacity.

To this end, work tables will be developed, in which all involved are involved.

After learning the applications from these tables no later than November 29, they will be sent to the contractor to present the load test schedule.

What does the Fund say?

Édgar Ortiz Pabón, director of the Fund, stressed that the aim is not to obstruct the process, but to carry it out, it is necessary to take the earlier steps to be followed.

"The main goal is to provide a job that primarily guarantees user safety, and therefore complies with all technical and security standards, securing the public funds invested," he said.

According to Ortiz Pabón, after receiving, together with Invías, an ETA audit office report – last Wednesday – a route covering four stages was proposed.

First, review and comprehensive analysis of the report and load test by Invías, which measures the actual stability of the bridge. Second, a specific answer on behalf of Interventoría to Invías' insights.

"The load test schedule should also be clearly defined, taking into account the comments made by the auditors and Invías, and finally the load test results will be analyzed to see if the bridge meets the technical safety and strength requirements because they have been contracted," noted Ortiz Pabón.

Therefore, he officially stated that without adherence to the route there will be no certainty as to the relevance of the results with regard to whether they correspond to new structure modeling, loads and geometry.


Hisgaura, considered the tallest cable-stayed bridge in South America, started construction in 2014 and invested 100 billion pesos, financed entirely by the Adaptation Fund.

Although the work is 100% ready, there is no load test that would guarantee the bridge's behavior with respect to the structure. And, of course, the safety of users.

According to the protocol and schedule, the test consists of two stages: static and dynamic.

The static test consists in loading the bridge with dump trucks and performing the topographic reading of the structure's behavior due to its mass.

In dynamics, the goal is to load and circulate the tippers by reading the frequency of vibrations through the motion effect.

Adaptation Fund and Comptroller have prepared a technical table

After the completion of the round technical table, organized by the Adaptation Fund and the Comptroller General of the Republic, it was clarified that, according to Interinstitutional Agreement No. 014 of 2012, Invías' participation consisted of validating monthly audit reports, participation in visits and visits. working committees and approves the road map of each act on labor and supervision.

Regarding the bridge lighting, it has been clarified that the contract provides that the contractor's obligation is to install the necessary safety components and new road traffic signs and road safety in accordance with the applicable standard.

"The 2015 road signs manual. Warns that the design must be compatible with the color and size characteristics, which are appreciated during the day, at night and during periods of limited visibility," said the adaptation fund manager.
