This project examines the history of construction technology of modern architecture and investigates how tropical modernism emerged through technoscientific practices of building such as reinforced concrete construction, formwork systems, scaffolding, material logistics, and labor organization across South Asia during the postcolonial period (1950s-80s). Drawing on architectural drawings, construction photographs, technical reports and institutional correspondence housed at Consortium member institutions, the study reconstructs how architects, engineers, development agencies, local actors and builders tested and adapted imported construction technologies on site. Existing scholarship on tropical modernism has largely privileged canonical architects and modern buildings as finished architectural products, overlooking the hidden layers of technological processes, labor negotiations, and material experimentation that made these works possible. By foregrounding construction as a site of knowledge production, this project reveals tropical modernism as a processual, labor-intensive, and technoscientific practice shaped through adaptation rather than transfer, contributing to the history of construction technology and postcolonial technoscience in the Global South.
