Project Description
Sector: Buildings
Client: Amarilo
Medellín, Colombia
Project details:
The Arkadia Shopping Center, located in Medellín, required the construction of six basement levels, reaching depths of more than 20 metres over an area of approximately 16,000 m².
The project presented significant geotechnical challenges, including high-strength rock layers and height restrictions due to its proximity to Enrique Olaya Herrera Airport.
To address these conditions, an anchored retaining system was implemented, enabling a large-scale open excavation while optimizing the construction schedule.
The solution included 80 cm-thick diaphragm walls extending to depths of between 18 and 24 metres, combined with more than 19,000 metres of high-capacity temporary ground anchors with capacities exceeding 140 tonnes.
During the works, approximately 340,000 m³ of material was excavated, with excavation rates reaching up to 4,000 m³ per day.
The entire anchored retaining system was completed in less than 12 months, allowing construction of the permanent slabs to proceed and helping meet the project’s demanding schedule.
Six basement levels and 340,000 m³ of material excavated in less than 12 months.
