Project Description
Sector: Buildings
Client: San Francisco Investments
Cartagena, Colombia
Project details:
The Four Seasons Hotel & Residences Cartagena, located in the historic Getsemaní district, presented an exceptional challenge due to its proximity to the sea, the presence of heritage buildings and the complex geometry of the excavation.
For San Francisco Investments, GEO developed a top-down solution covering an area of approximately 3,600 m², combining ground preparation works with nearly 10,000 m² of diaphragm walls and deep foundations using piles, barrettes and micropiles.
The solution enabled approximately 20,500 m³ of excavation beneath the slabs, while controlling uplift pressure, water ingress and potential movements of adjacent structures.
The project is part of an approximately 30,000 m² hotel complex combining historic buildings with new construction.
The successful completion of the foundations and basement works strengthened the client’s confidence and led to GEO’s scope being extended to include construction of the superstructure, making the project a benchmark for integrated solutions, from deep foundations through to the structure.
A 6.5 m-deep excavation carried out in a sensitive coastal and heritage environment, with groundwater control and protection of adjacent historic structures.
