Special Structures

Working in different ways in the execution of engineering projects is one of our hallmarks.

Plants, dams, irrigation, and other unique projects have been made possible based on the experience and expertise we have acquired over decades of constant business development and hundreds of construction works carried out.

Mananciais Program | SP


Construction activities aim to implement the Program for Sanitation, Environmental Protection and Recovery of Water Quality in Degraded Areas of River Springs in the Guarapiranga and Billings Basins.
The project will benefit more than 3,600 households in the community with urban infrastructure works, including drainage, soil and slope retention, laying sewer pipelines, and urban development works that include new housing units, street paving, walking paths and leisure facilities for the local population.

Bio-Manguinhos | RJ

Carioca was responsible for three phases of construction at the New Center for End-Stage Processing of Vaccines of Bio-Manguinhos, on a 580,000-m² block of land located in the city of Rio de Janeiro.
In phase one, more than 6,000 piles were driven. The earthmoving phase handled approximately 2,000,000m³ of soil in two years of work. In the last phase, which included blocks and straps, we used 20,000m3 of reinforced concrete and installed more than 6,000 anchor bolts in the foundation blocks and beams, in more than 20 buildings in the project.

Porto Maravilha | RJ

The Porto Maravilha project, Brazil’s largest public-private partnership, covers an area of more than five million square meters in the downtown district of Rio de Janeiro. It consists of refurbishing the port and harbor area, making significant social, economic and cultural impact on the whole city. We carried out a complex range of construction works, including new water and sewer pipelines, redevelopment of 70 kilometers of roads and sidewalks, bike paths, and major construction challenges such as dismantling the Perimetral Overpass, and building the Via Binária Tunnel and the Via Expressa Tunnel, which replaced the Perimetral Overpass.

Funil Dam | RJ

Built in 1969, the Usina do Funil plant continues to be the largest double-curvature arch dam made in Brazil. The plant is part of the Furnas power generation system, with a capacity of 216 MW. At the time, it had an important strategic significance, as it was the first hydroelectric plant built between Rio and São Paulo. The 85-meter-high dam consumed 450,000 cubic meters of concrete in its construction.

Transposition of the São Francisco River | PE

Laying the São Francisco River transposition channel, with a length of 39,128 meters, and other complementary structures, which included the construction of a 986-meter water pipeline, a 726-meter tunnel, footbridges and bridges. This stretch is part of the North Section, which is entirely located in the city of Cabrobó, in the state of Pernambuco.

Grande Moinho Aratu | BA

Setting up the M. Dias Branco Group plant in Aratu, Bahia. A climbing formwork system was used to build 21 reinforced concrete cylindrical silos measuring 65 meters in height and 10 meters in diameter, and 78 rectangular silos, in addition to construction work in the pasta and biscuit factory, the administration building and auxiliary facilities. The project also included the construction of a 292-meter long, 23-meter wide multipurpose pier.

Paraitinga Dam | SP

Construction of a 425-meter long, 8-meter wide earth dam to form a storage basin to retain floods and supply water. Electromechanical water intake equipment was supplied and assembled.

Eletrobolt Thermal Power Station | RJ

Earthmoving, drainage, paving, water catchment structure and construction of a power plant with a capacity of 386 MW in the city of Seropédica. Earthworks involved 1,200,000 cubic meters of landfill.
