Summary

The video records the opening event of the exhibition ‘Infrastructure in a Time of Flux: Methods, Conditions, and Situations’ at Harvard GSD. Dean Sarah Whiting introduces the event, then curator Rahul Mehrotra presents the exhibition’s theme: exploring how infrastructure can be designed to embrace change rather than permanence. Mehrotra traces his research trajectory from his thesis on Mumbai to the concept of the ‘kinetic city’ and the ephemeral urbanism. He discusses the exhibition’s three sections: methods (lightweight structural systems), conditions (environmental and political forces), and situations (specific spatial formations like refugee camps and festivals). The presentation includes a discussion of the Kumbh Mela, the tent as an architectural object, and the work of Christo and Jeanne-Claude. The event also features a presentation by Vladimir Yavachev of the Christo and Jeanne-Claude Foundation about the Running Fence project. The talk concludes with a Q&A session.

Critical Evaluation

Value of the Information & Strength of the Argument

The talk provides a comprehensive overview of a critical rethinking of urban infrastructure. The argument for integrating impermanence into design is presented logically, drawing on multiple case studies and theoretical frameworks. Mehrotra’s notion of ‘reversibility’ as an epistemological category is compelling and well-illustrated. The presentation is persuasive, though some concepts may require prior knowledge.

Scientific Rigor, Source Quality, Title Accuracy

The speaker is a renowned professor and the content is based on published research and an extensive curated exhibition. The talk references specific projects and publications, but lacks direct citations of external sources. The title accurately reflects the focus on infrastructure and flux. No comments were provided, so audience feedback is not analyzed.

Chapters

Cited Sources

  • Running Fence (1977) documentary film — Mentioned in introduction and presentation as an example of temporary public art infrastructure.
  • MAG magazine issue on tents — Curated by Rahul Mehrotra, discussed in relation to the tent as an architectural archetype.
  • Mapping the Ephemeral Mega City — Book by Rahul Mehrotra on the Kumbh Mela, cited as a foundational research output.

Contribution & Novelties

The presentation advances the concept of ephemeral urbanism, challenging the traditional association of infrastructure with permanence. It offers a taxonomy of methods, conditions, and situations to analyze and design for impermanence, introducing ‘reversibility’ as a new design principle. The talk also bridges urbanism, architecture, and structural engineering, and highlights the role of art in prompting public engagement with these ideas.

Pour aller plus loin :

  • Temporary urbanism — Related concept in urban planning.
  • Ephemeral architecture — Design approach focused on transience.
  • Kumbh Mela — Example of a large-scale ephemeral city discussed in the talk.
  • Christo and Jeanne-Claude — Artists whose Running Fence illustrates temporary infrastructure.
