Building of the cross-Tagus bridge in Portugal

The new bridge, connecting Carregado and Benavente is at present the largest public works project in Portugal. The bridges are being built across the River Tagus, without damaging the environment or interfering with farming activities. PVE Cranes & Services and Dieseko Verhuur BV, both linked to the Van Es Holding Group supplied all necessary equipment for the on site piling job.
PVE Cranes & Services supplied 9 crawler cranes, ranging from 50 up to 250 tons, and Dieseko Group supplied their largest vibratory hammers with power packs, 4 models of PVE105M and 2 models of PVE200M. This is the philosophy of the Van Es Holding Group, SYNERGY. The group of companies is able to offer a complete package of heavy equipment with local service, anywhere in the world.

The Lez_ria Grande area of Vila Franca de Xira (a town about 30 km north of Lisbon) where farmers cultivate their fields alongside the largest public works project now under construction in Portugal. The cross-Tagus bridge links Carregado and Benavente. This 14 km long suspension bridge is to expand the nation’s road system to cross both the river and the Ribatejo Lez_ria without a negative impact on the environment or farming activities. This presented an interesting challenging for the builders. Each company of the consortium, SPFE, OPCA brought in its people and resources, and started with intensive teamwork.

Magnitude is the correct word for a project involving massive figures
For example, it required 54,000 linear meters of piles and foundations reaching depths of 55 meters. The pre-casting plant turns out 4 concrete beams daily. Each beam is 35 to 44 meters long and weighs up to 120 tons (metric tons). The project uses 150 tons of cement per day. On the section spanning the river, concrete will be poured which is transported through a 900 meters long pipeline. There are 5 concrete batching plants set up along the 14 km construction site and 14 bridges have been built on the service road.

These bridges span the rivers, brooks and drainage channels that flow through the alluvial plain. One thousand persons, of 14 different nationalities are working on the project, including 850 living in accommodations at the jobsite. This international spirit is
an integral part of other aspects of the project as well. The floating equipment and vibratory hammers are Dutch, the cranes, which can lift up to 250 tons are Japanese, German and English. Italians designed the precasting plant and the foundations are the responsibility of the Brazilian company Brasfond. The client is Portuguese, Brisa Engenharia e Gest_o, a subsidiary of Brisa Auto-Estradas de Portugal, the largest tolroad operator in the country.
