The Port Authority of Valencia has awarded these works as an emergency to SACYR Construction, due to their ruinous state, impossible to restore, and the danger to navigation. A 136-metre-long floating pontoon with a crane installed that has the capacity to load pieces weighing up to 1,400 tonnes is already working on the Port of Sagunto’s marshlands. With this operation, the concrete blocks and hoppers (devices similar to a large funnel used for depositing and channelling granular materials) will be removed from the structure of the marsh. These actions are part of the works to dismantle the Sierra Menera Dam deck, which the Port Authority of Valencia put out to tender by emergency procedure and awarded to the company SACYR ConstrucciónPreviously, the workers have been working on the preparation and cutting of the slabs of section 3, the supply and assembly of load lifting outriggers, the placement of anchors with auxiliary vessels on which the pontoon carrying the crane will be fixed, etc. Some 50 blocks, mostly weighing 250 tonnes, are to be removed. The technicians will first proceed to remove the 5 hoppers weighing approximately 10 tonnes each, followed by the metal structures at the end of the pontoon and finally the concrete boards of the deteriorated structure of the pontoon.The works on the Pier are in response to the emergency plan activated by the PAV after the last collapse of part of the infrastructure on 28 September 2023, where three spans fell, specifically 9, 10 and 11, those in the worst condition “without the need for a storm with the sea calm at sea, which showed the poor state of the installation which cannot be repaired”. The whole area was already marked out by Valenciaport after the first incidents. After studying and analysing the state of the marsh, and for safety reasons given the impossibility of limiting access to the area despite the signage, it was decided to dismantle the part at risk and these works were carried out to guarantee safety in the area.
