The first direct reference to the plan of this new establishment appeared in an advertisement published in the Programma Guiador newspaper in January 1887. Here, the new Moinho Fluminense Sociedade em Commandita Gianelli & Cia limited partnership was introduced to the public.58
The confirmation of the Jannuzzi brothers as the entrepreneurs building these new facilities appears in the report of the members of the Instituto Philitechnicos institute, written after their visit to the Gianelli & Cia workyard.59 They enriched this report with technical information on the process used for laying the foundations of this new business, as it is located on a landfill, close to the sea.

Attributed to Antonio Jannuzzi & Irmão, the designer of this architectural project is confirmed in an article written by G. B. Ricci that was published in 1908.60 When listing the best buildings constructed by this firm, G. B. Ricci mentioned the “majestic and colossal” building that houses the Moinho Fluminense mill. This admiration is echoed by contemporary critics, who highlighted the buildings forming this mill and the old Modesto Leal jetty.
Examples of British ‘utilitarian’ architecture, these two buildings achieve a perfect balance among the selected materials, the styles used and their functions.61

Shaft Process used for the foundations of the Moinho Fluminense complex
As this is an industrial plant that involves considerable weight, and as the land acquired for this purpose is close to the shore, the plan is to lay the foundations using the shaft process. This method is based on a series of excavations. After the first, up to three meters deep, hollow wooden cylinders are seated at the bottom of the trenches. Cemented stones are placed on each cylinder. While excavation continues within the cylinder, in parallel, stones are used to build a circular containment wall. The use of this method allows the construction to move downwards under its own weight, until reaching a resistant layer. These foundations may extend to depths of eleven meters before reaching bedrock. During excavation, all inflowing water is brought to the surface by a steam-powered centrifugal pump made in the USA.
