Senna Tower Foundation Completed as Project Advances to Vertical Construction

Overview

• The foundation phase for the roughly 550‑meter Senna Tower in Balneário Camboriú finished in mid‑July, allowing the project to move into infrastructure (embasamento) work and the start of vertical construction.
• União Fundações says it executed more than 1,000 continuously monitored CFA (helical) piles up to 42 meters with electronic tracking, while FG Empreendimentos reports 798 Auger Cast piles to 40 meters and a 70‑working‑day completion, creating a clear numerical and method dispute between contractor and developer.
• União Fundações invested in a MAIT CFA 34‑36 rig at about R$15 million to carry out deep monitored pile work, a detail the company highlights to support its claim of electronic monitoring and traceability.
• FG Empreendimentos reported commercial progress: a VGV above R$8.5 billion, R$2.48 billion in sales to date, a 228‑unit program across 157 floors, and roughly 10% of sales to foreign buyers, underlining strong demand in the ultra‑luxury segment.
• The project ties large‑scale engineering to brand and cultural elements linked to Ayrton Senna, and the foundation completion both accelerates construction jobs and raises the need for independent verification of technical tallies because those figures affect oversight, procurement and investor confidence.
