A 19m deep excavation for a landmark high-rise building known as Downtown One was recently completed in Tirana Albania. The building will feature 5 floors of underground parking.
The deep excavation support system consisted of a reinforced concrete diaphragm supported by three to five levels pretensioned ground anchors. The excavation support system had to protect a neighboring four story concrete building, and a two story adjacent parking. Thus, soil and wall deformation control was very important to the project success.
The deep excavation design was completed in 2017 with DeepEx and all inclinometer monitoring is being performed with SiteMaster 2018 by Deep Excavation LLC.
