DEMOLITION FCC PROVISIONAL OVERPASS

March, 2016

Demolition of a provisional overpass over the river Pámanes (PK 9 + 400) of the Solares - La Encina highway. The company contractor of the work has been FCC Construccion SA.

The overpass was built for use as an interim step during the construction of the motorway. Once this work ended, we proceed to demolition. This is a step composed of three concrete beams (60 cm thick), with a reinforced concrete slab (30 cm thick), 5.5 m wide and 9 m long. The weight of the structure was 54 tons.

Lifting and removal of the structure was made in just one piece, embracing the three beams and the board together. Previously it was necessary chopping the board joints with a backhoe with hammer, thus ensuring separation between the two structures.
The pieces were raised and deposited in the bank of the river, where a backhoe with hammer finally chopped the beams and slab, for transport to an authorized landfill.
Also the bridge abutments were mechanically demolished, leaving the debris generated for transport to an authorized landfill.
