MOTA-ENGIL ENGENHARIA DEVELOPS REINFORCED
CONCRETE STRUCTURE FOR ASM OFFSHORE
WITH A UNIQUE SIZE IN PORTUGAL, THIS STRUCTURE REQUIRED A NEW METHODOLOGY.
At the beginning of 2018, the Prefabricated unit of Mota‐Engil Engenharia e Construção started the production of a new reinforced concrete industrial structure of unparalleled size in Portugal.
ASM Offshore, located in the Port of Aveiro, was developed with a floor area of about 20,000 m2 and a height of 21 m. The specificities of this work, namely the height of its pillars and the system of connection of pillars by sheath, implied
very tight execution tolerances.
This berth was designed for overhead cranes with a capacity of 150 metric
tons and involved the execution of post tensioning of bars on‐site, a challenge accepted and implemented by Mota‐Engil Prefabricated unit.
Given the size of some of the pillars expected for this work, with a section of 1.05x0.70 m and a total weight of 51 metric tons, and the fact that the use of piles in their foundations is necessary,
a system of “embedding” the pillars different from the usual one was defined. The in situ footings were made leaving sheaths where the pillars would later be placed and sealed, whose lower section would have ø32 irons, where the greatest length would be 3.15 m.
This work had an assembly duration of three months, with 563 prefabricated elements being produced and assembled, totalling a volume of over 3,700 m3 of concrete.
