OPERATION MARHABA: Strategies for Collapse Management

Escuela Técnica Superior de Arquitectura de Madrid

Project idea

The project proposes an innovative alternative to manage the Operation Strait of Gibraltar, which causes a logistical and environmental collapse in Algeciras every summer. Instead of viewing the operation as a mere transit of vehicles, the idea is to transform it into an opportunity to regenerate urban spaces and improve the quality of life for both travelers and residents. The project, named Operation Marhaba, suggests using urban gaps created by hyperindustrialization as temporary waiting spaces, integrating ecological, logistical, and urban solutions. This intervention aims to turn waiting into part of the journey by creating resting and meeting spaces in a naturalized environment.

Project description

The project Operation Marhaba seeks to reformulate the traditional Strait of Gibraltar operation by implementing a system of territorial locks in selected urban voids, such as the Algeciras Fairground. These locks democratize and dignify the waiting process by coordinating the arrival of vehicles and the departure of ferries to prevent collapses. A process of ecological rehabilitation is proposed, where concrete pavements will be lifted to create renaturalized parks. These spaces will include modular devices allowing flexible use, functioning as ventilated parking areas in summer and as leisure and meeting areas throughout the rest of the year. The infrastructure will incorporate photovoltaic slat systems and thermal terraces to improve climatic comfort, as well as collect water and solar energy.

Technical information

The project is based on the implementation of a multifunctional urban support structure measuring 288 meters long, divided into six independent structural segments. The main structure includes a three-dimensional lattice that supports hanging tramex terraces and tensioning systems, allowing for the flexibility of the interior space. The building will house modular devices that can be deployed and retracted as needed, facilitating the transition between use as a parking facility and as public amenities. The southwest facade will be designed with photovoltaic slats for solar energy collection and to create an informative display. On the northwest facade, a hanging tramex terrace system with a metal structure acts as a thermal buffer in winter and allows for the opening of the entire building in summer. High-albedo pavement and vegetative barriers will contribute to reducing radiation and filtering air. On the roof, self-production greenhouses and water collection systems will be installed. The combination of these urban and construction strategies aims to provide flexibility and thermal comfort, adapting to different programs and seasons of the year.
