Ground shoring “Andén Retiro”, Madrid


Incye was hired by Ferrovial Agromán S.A. to design and install the groundshoring solution for Andén Retiro development, located at 58 Cavanilles st, in Madrid. The shoring system reached 5 levels below ground and the excavation comprised diaphragm walls, concrete piles and micropiles. The lot will house 216 households, offices, commercial premises, garages and storage rooms.

Additional information

The lot is L-shaped with a length of 56 meters on the long side and 33 meters on the short side, and a width of around 18 meters. 

At level 1 the shoring system is anchored to the cap beam, while in the rest of the levels the shores withstand earth pressure acting on concrete piles in one area, and micropiles in another. Therefore, it was necessary to use INCYE300/INCYE450 waling beams in conjunction with the shoring elements.

When it comes to design, Incye’s goal is to always conceive a clutter-free plan so the construction teams can optimize working times thanks to minimal interferences with the shoring system. When the lengths of struts do not exceed 20 meters, the best option is the PIPESHOR tubular shores. As they do not need lateral bracing, they provide a very clean design that allows the rest of the construction trades to work at higher yields.

Moreover, the two lower levels had to be dismantled under their respective slabs. Thanks to the use of tubular struts with no need for lateral bracing, the reticular formwork system for the slabs was easily set up.

The conception of the design was carried out in collaboration with Valladares engineering and Ferrovial’s technical services. Incye fosters, whenever possible, joint work with the engineering firm that designs the diaphragm walls. The shoring-diaphragm walls system must be conceived as a whole, because the stiffness of both systems influences the design and cost of the global solution.
