The MG4 is a complex that encompasses three integrated recording studios and was built with the most advanced technology, with the objective of ensuring the compatibility of the equipment and infrastructure facilities and the station's technology area.
The total built area of the new building is 27,000 m², divided into three large blocks: support building, studio building and storage building.
The constructive solution adopted in the project is mixed. In the case of the support building, the project design sought to consider as few pillars as possible to provide greater layout flexibility in the environments provided for in the program. There are three floors of predominantly horizontal architecture, the ground floor, the first and second floors, in addition to the roof. The building also has a mezzanine, technical floor and a metal structure roof. The external seals are made of brickwork and the internal ones, for the most part, are made of drywall. The largest span area of this building is located in the ice-water plant, located on the 2nd floor, with approximately 24 m.
The studio building, on the other hand, was conceptually designed to form “large boxes” with the highest possible insulation, acoustic efficiency, safety and flexibility of use. They are composed of walls, pillars and reinforced concrete roof slab, internally covered with fire-resistant agglomerated reforestation wood wool acoustic panels. This building has the largest free space in the project: 48 m. The two support areas between the studios are divided into three floors (ground floor, 1st and 2nd floors), following the same concept as the support building: reinforced concrete pillars and beams and unidimensional ribbed slabs. The concrete walls of the studios are being executed with climbing shapes.
The storage building was designed to be a large warehouse and as such the project was designed to allow the spaces to be adapted according to the customer's demands. For this purpose, prefabricated concrete pillars and concrete block fences up to the level of the first floor were considered, complemented by metal braces up to the roof level around the entire perimeter of the building, which provide a free ceiling height of 10.50 m, and the roof in a trussed metal structure guarantees free spaces of up to 33 m. Internally, the building has two areas with operating environments, both developed on two floors with a metal structure.
In general, each area of the new module has a specific size for permanent and accidental loads, varying between 100 and 500 kg/m² according to the type of use. In the case of studio floors, due to the variety and size of equipment to be used and, especially, the unpredictability of the type of use, a maximum distributed load of 5,000 kg/m² and a maximum concentrated load of 3,000 kg/m² were considered.
The entire project was developed on the BIM platform, which allowed greater compatibility between all disciplines (architecture, structures and installations), whether in areas where building systems are prefabricated or molded on site, which brings greater efficiency in the execution of areas that require special attention.
