Before the project starts, a research was made on the original projects of architecture, structure, water and electric instalations. This research revealed the principles that have oriented the original project. This restoration project never intent to recreate an original situation, but the research was essencial to define contemporary interventions. The careful removal of coatings allowed the comprehension of many interventions the building suffered that had no register. This research also sustained the decisions towards the finishing materials and colors. Since 2010 there was an assumption that the overhanging shelf might be suffering a structural collapse, therefore it was propped. In 2014 prospections and measurements were made to evaluate its structural conditions. The topographic assesments presented variations that were considered within the normal parameters for this structure. The prospections revealed the existence of exposed and oxidated iron hardware without compromising its section and structural performance. All the finishings, sealing and filling material were removed. The iron hardware and the concrete treated so that the slab could be filled with light material and the new finishings executed. The rainwater capture was conceived from three original planters implanted over the shelf, collecting the water and conecting to the cast iron piping concreted inside the pillars. In a previous remodel these planters were filled with waste. The current project recover the original rainwater capture system. However the planters won't be renovated, there is an elevated floor implanted over them, so that the water can be collected through the floor.
