Operation in downtown Passo Fundo gathered trucks, boom pumps, steel, and ice to execute a large-scale foundation in a vertical construction. The concreting drew attention for the volume applied, the urban logistics, and the technical control required in a structure of this size.
A concreting operation mobilized 92 mixer trucks on Monday (06), in downtown Passo Fundo, to execute the central foundation block of the Ícone Building, a 33-story tower by Point Construções e Incorporações.
According to O Nacional, the block exceeded 730 m³ of concrete and became the largest in volume ever executed in the municipality.
Started in the early morning, the concreting began at 5:30 AM and required the interruption of traffic on Capitão Eleutério Street, in the section between Brasil Avenue and Paissandu Street.

To maintain constant supply, the logistics organized the timed movement of trucks between Concreteira Andreetta, on RS-324, in São João da Bela Vista, and the Point construction site in the city center.
Foundation of the Ícone Building moves downtown Passo Fundo
Built in the area where the old Giongo Building used to be, the Ícone Building occupies one of the busiest regions of Passo Fundo and is part of the advancement of large-scale vertical constructions in the municipality.
According to Sérgio Panizzon, CEO of Point, the project will have 33 floors “in the heart of the city”, in an execution phase that also welcomed engineering students during the preparation and piling.
During the continuous concreting, the 92 mixer trucks supplied two boom pumps, equipment used to transport the concrete to the application point with greater reach, precision, and agility on the site.
By 9:30 AM, according to the operation report, 32 trucks had already unloaded the material, indicating progress within the schedule planned for that morning’s work.
Due to the scale of the intervention, teams from the construction company and the concrete supplier needed to coordinate the flow of trucks, the operation of the pumps, and the circulation in a central area of the city.
In total, about 30 professionals participated directly in the stage, including workers responsible for distributing the concrete within the foundation block prepared to receive the projected volume.
Central block has 68 piles and supports 14 pillars
Responsible for the construction, civil engineer Isaac Canali explained that this stage corresponds to the central foundation block, a structure that concentrates an essential part of the building’s support.
According to him, the block comprises 68 piles with a diameter of 70 centimeters, from which 14 pillars originate, responsible for forming the structural base of the tower.
“We are executing a block that we call the central foundation block. It is a block that encompasses 68 piles with a diameter of 70 centimeters. In this block, 14 pillars are born that will provide the structure of our tower,” stated Canali, detailing the function of the set within the project.
In addition to the significant volume of concrete, the foundation received approximately 60,000 kilograms of steel, material used in the reinforcement of the central block executed by Point Construções e Incorporações.
Combined, concrete, steel, and piles form the base prepared to support the 33-story tower planned for the development under construction in downtown Passo Fundo.
Ice in the concrete helps control internal temperature
Among the technical aspects of the operation, the use of 50,000 kilograms of ice incorporated into the concrete mix drew attention for its direct role in the thermal control of the block.
The measure aimed to reduce the core temperature during the cement hydration, a reaction that releases heat and requires special monitoring in large-volume concrete structures.
Canali explained that, as it is a robust block, cooling helps prevent the internal temperature from exceeding 65 °C during the curing process.
In the engineer’s assessment, excess heat could cause cracks in the concrete and, over time, compromise the metal reinforcement due to corrosion.
This stage also included quality control of the applied material, with manual collection of cylindrical samples to verify the consistency and strength of the concrete.
This technical monitoring allows for evaluating whether the material placed in the block meets the requirements set for the foundation, especially in a structure with a high volume of concrete.
The technology also appeared in the use of boom pumps operated by remote control, a solution that assisted in supplying the block during the continuous movement of trucks.
Even with support equipment, an important part of the execution depended on the direct action of professionals on-site, especially in distributing the concrete within the prepared area.
Concrete curing should take about 28 days
After the concreting, the block goes through the curing period, a necessary step for the concrete to develop strength according to the conditions outlined in the structural project.
According to Isaac Canali, the estimated time for this process is approximately 28 days, considering the large block executed in the center of Passo Fundo.
The operation stood out not only for the number of trucks involved but also for the scale of materials applied in a single stage of the foundation.
In a few hours, the construction concentrated more than 730 m³ of concrete, about 60 tons of steel, and 50 tons of ice in a structure prepared to support the future tower.
With the central foundation underway, the Ícone Building advances into a decisive phase of construction, while the block follows the necessary period for strength development.
For Passo Fundo, the execution shows how large-scale vertical constructions can alter the routine of central areas, requiring integration between engineering, logistics, traffic, and urban operation.
Does concreting of this scale change the way Passo Fundo follows its major constructions in the city center?
