This is the construction of the First Phase of the Málaga Track and Field Stadium, which consists of building sports tracks, access points and stadium seating along the side straight with the exit and entrance. All of this was set within a global project, which consists of totally enclosing the stadium, creating a sports complex formed by the Palacio de los Deportes Martín Carpena and the aforementioned Track and Field Stadium.The construction work in question consists of building the side stadium seating, which will be three stories high, one level recessed over the next and supported by a frame comprising the profile of the bleachers, which also encloses the outside of the stadium. Steps are made of prefabricated concrete plates, and the roof is made of a three dimensional metallic structure supported by porticos and roofing via sandwich type panel.

This is the construction of a metro station in a tunnel, requiring and very short project turnaround time. It was necessary to come up with a method that would enable the construction of large scale side walls, leaving open only a center strip of 4.50 m to execute thereafter.It is considered the construction work with the largest cross section in Brazil.

The Sulfuro Primario de Cerro Verde Project is a macroproject for the expansion of the Cerro Verde mine, which has the objective of tripling copper production.Experience gained from the Toquepala Project was of great help to ULMA Construcción when confronting the new challenges posed by this work. It is also worth mentioning that the largest construction companies in Peru participated in this project.The project encompassed the construction of the first, second and third crushers, Silos, Mills, Flotation System, Grinder, Recycling Chamber, Filters, Warehouses, etc. Some of the most important structures to be specially considered are the silos, which are 41 m high structures with an area of 1625 m², and the mills, which are large block structures of 5 m high and within an area of 1550 m².

A portion of the stadium seating from the fire, which devastated the old Sports Complex, was salvaged when constructing the new one in the same location. New stadium seating and a new roof were built. Likewise, various parking garage levels were added, giving way to a new modern building.
