The scarcity of space in coastal towns due to rising sea levels and limited land availability in rapidly growing coastal communities has prompted the practice of land reclamation. The SEAform project aims to create settlements that are seamlessly integrated with the maritime environment using a system of modular floating platforms. This thesis seeks to evaluate and compare the SEAform technology solution with the current methods used in Land Reclamation (Infill and Hydraulic Fill land reclamation) to help decision-makers select the most appropriate option for their specific project needs. This thesis intends to evaluate and compare the costs, marine environmental impact, and contribution to global warming of floating platforms and Land Reclamation Infill and Hydraulic fill methods to identify the most efficient approach for land reclamation projects.
