Construction of a new hospital within the footprint of the existing one, to increase capacity with 520 additional beds. Studies for excavations by micro-blasting in rocky ground, with modelling of the interaction of blasting with the existing hospital. Reinforced concrete earthquake-resistant structure, columns, beams and windbracing walls. The structure consists of 20 independent freestanding blocks. Construction is performed in several phases (decanting operation) without interruption of hospital activity.
