Sea Wall



    Sea Wall is a 3D printed modular green infrastructure aiming to defend, adapt and mitigate sea-level rise by robotic fabrication for pre-fabrication as well as construction sites. It will be deployed on the waterfront in multiple scales of the freeway 101 in the Bay Area, providing and sustaining habitats for sorts of species that have lost their homes due to global warming and water pollution.

  • Materiality

    Material and formal studies, such as constructed landscape permeability and bio strategies, along with local aquatic organism studies have been investigated to inform the physical forms of the design and texture, in order to justify the concept of cohabitation and sea level rise control.


    Academic Study Example - Tsing Yi 2100


    The porous structure of the prototype requires advanced fabrication skills for manufacturing. Explorations of 3D printed construction materials such as clays, geopolymer cement and carbon fiber and approaches of how to achieve it - carving, casting or assembling are our next steps. It is possible to use mixed materials to increase strength and durability of the composite materials


    The main advantages to use the 3D-printing technology for building structures include the ability to achieve a more complex geometric structure, quicker construction, lower labor and construction costs, and produce less waste.


    Investment in green infrastructure is huge in the Bay Area. The constructions often take a lot of time and resources and most of them are actually violations of environment. Combined with technology innovation the Sea Wall would significantly increase the effectiveness by robotic fabrication, which eventually costs less time and money.

  • Team

    Lili Dai conceptualized and did the preliminary research of Sea Wall during Spring 2019 and Elnaz Tafrihi joined the team in Fall 2019. Together, they are working on exploring the logistics of robotic fabrication of construction materials for environmental problems worldwide. We are currently on the residency of Autodesk Pier 9 and CITRIS Foundry at UC Berkeley and we are seeking all sorts of resources in the near future.
