The document discusses mapping the networks of project-based work in London's architecture and construction industries. It proposes using social network analysis to map connections between people and companies working on building projects. This would provide a quantitative understanding of intra-city networks in a highly project-based industry. Qualitative research methods like interviews could then complement this by providing insights into how project-based work is actually practiced. Comparing projects across cities could also show the international scope of certain firms and individuals as well as the global nature of construction supply chains.
