The Expansion and Development Plan for the Port of Santos was commissioned by the Brazilian Special Secretariat for Ports and funded by the Inter-American Development Bank to serve as a planning and managing tool to support the prioritization and selection of projects needed to accommodate increasing demand for port services. The Louis Berger Group conducted pre-feasibility assessments (environmental, economic and strategic evaluations) of 25 development alternatives at 16 sites. We also performed technical and financial/economic pre-feasibility studies for five selected terminal development options to be implemented in the short term. LBG prepared five-year strategic development plans in close coordination with Brazilian Secretariat. Our work involved the development of quality and operational efficiency programs, programs for improving and expanding the ports infrastructure, including modernization and expansion programs; development of a demand-analysis model to analyze national and regional cargo flows; and implementation of tools to monitor the development plans. We also incorporated sustainable development into the plan to develop the Santos port complex in harmony with the city’s requirements for improved traffic and to limit the environmental impacts. Our multidisciplinary professionals conducted an extensive array of analysis. We evaluated the port’s connectivity, including an in-depth analysis of road, rail and channel planned improvements. LBG professionals also conducted a strategic diagnosis of the port’s competitiveness, developed a 15-year demand forecast for bulk and general cargo, and developed a demand allocation model connecting the production and consumption centers in the country’s central and southeastern regions with foreign destinations or origins.
