Concrete prefabrication and offsite construction in Brazil : a development case study in Mato Grosso

Abstract

With a large, growing, and young population, Brazil suffers from a chronic shortage of affordable housing. This crisis, in particular, negatively affects new and economically ascending entrants to the housing market. This economic crisis is unfolding concurrently with the global environmental challenges associated with climate and sustainability. This thesis explores the application of modular construction in an affordable housing project in Cuiaba, Brazil. This thesis is comprised of three distinct sections. Section I provides a historical overview of offsite construction with a particular focus on precast concrete in modular construction. It describes the forces and some of the most notable projects and figures that shaped precast construction - especially in its European cradle. It further provides a comprehensive classification of current modular construction and discusses its benefits and limitations. Section II analyzes Brazil's ongoing housing crisis and Brazil's economic trends and realities. It discusses Brazil's National Housing Policy and its flagship program - Minha Casa, Minha Vida. Section III takes the reader to Cuiaba, Mato Grosso's capital, and proposes a 528-unit affordable housing development project there. It explores the establishment of a mobile concrete precasting plant and analyzes the production and application of a novel modular concrete system in the project. Particular attention is paid to the financial viability of the project.
