ABSTRACT
Geotechnical and structural instrumentation and monitoring have developed significantly in recent years, with the emergence of new technologies, such as medium and long-range wireless transmission equipment, that allow faster and more efficient data collection and transmission. The article proposes the performance analysis of a retention wall structure defined for an urban excavation in Lisbon using an automated geotechnical monitoring plan. It discusses the benefits and potential improvements in implementing geotechnical monitoring solutions in national projects. The monitoring plan defined uses different instruments, including vibrating wire piezometers, MEMS load cells, Shapearray automated inclinometers and biaxial tiltmeters, which provide several daily readings available in a remote and online acquisition system. The objective is to ensure the best conditions of the solution’s safety, efficiency, and cost, reducing the uncertainties inherent to geological-geotechnical conditions through the Observational Method.
