Ensuring the longevity of a unique infrastructure
Built between 1981 and 1986, the causeway was designed with an anticipated lifespan of 75 years. As one of the busiest cross-border transit routes in the world, it is now midway through its planned operational duration. The King Fahd Causeway Authority requested a thorough assessment of the infrastructure’s current condition, accompanied by recommendations to extend its lifespan. This work had to be conducted with minimal disruption to traffic.
Extreme climate conditions
Crossing over the Gulf of Bahrain, the causeway is exposed to a harsh marine environment, characterized by high humidity and salinity, both of which can compromise the durability of its concrete structures.
These climatic challenges also impact project execution, especially working hours. During the summer months, work is restricted between noon and 3pm to mitigate risks associated with extreme heat and humidity.
From paper to GIS (Geographic Information System)
A detailed review of the original as-built plans and construction records provided valuable insights into the design of the structures, particularly the bridges. However, certain gaps were identified, requiring additional geotechnical analysis to better understand soil properties.
To enhance future maintenance, a digital twin of the infrastructure was developed as part of the project. This digital representation streamlined the organization and documentation of maintenance activities, ensuring more efficient management of activities.
