Chain Drain: Why the Built Environment Can't Learn

How can rethinking the handoffs between design, real estate, and construction rescue the built environment from decades of declining productivity?

In this special episode of Practice Disrupted, host Evelyn Lee explores the systemic productivity crisis in the built environment through the lens of "Chain Drain", a paper from the University of Michigan. Evelyn sits down with co-authors Bryan Boyer, who teaches architecture at Taubman College and co-founded the studio Dash Marshall, and Greg Lindsay, an urbanist in residence at the University of Toronto School of Cities. Together, they examine how fifty years of falling productivity stems from value and intelligence leaking out at the handoffs between stakeholders, rather than failures within individual firms.

The conversation covers how traditional architectural firms face immense pressure, why AI acts like a "microwave" that accelerates existing workflows without solving core strategic problems, and how accountability ultimately rests with the asset owner. The guests detail their four VCR-inspired scenarios - Play, Fast Forward, Eject, and Pause - evaluating how digital transformation, supply chain innovation, and radical reuse will dictate the future of practice.

Ultimately, the discussion challenges practitioners to rethink their business models, improve decision-making workflows, and look beyond the traditional atelier. By embracing technical skills and engaging directly with the broader supply chain, professionals can reclaim their agency and help shape a more resilient built environment.

"We need to break the addiction to the idea of the architect's identity being an architect who is in, if not leading, an atelier. It's also limiting our ability to meet the needs of society and to produce a high quality built environment if we say that our work can only happen in this one setting." - Bryan Boyer.

This episode serves as a vital wake-up call for the AECO industry, proving that addressing structural inefficiencies requires more than better tools, it demands a complete reimagining of how we organize, collaborate, and make decisions.

Guest:

Bryan Boyer is an architect, educator, and co-founder of the architecture and strategic design studio Dash Marshall. At the University of Michigan, he directs the Master of Urban Technology at Taubman College and is the first faculty director of the U-M Center for Innovation in Detroit. Before Dash Marshall, he co-founded Helsinki Design Lab at the Finnish Innovation Fund, and he started his career in tech, designing and programming user interfaces for early-stage startups.

Greg Lindsay is an urbanist, journalist, and urbanist-in-residence at the University of Toronto’s School of Cities. A former senior fellow at Cornell Tech and co-author of Aerotropolis, he writes and researches extensively on the future of cities, technology, and the built environment, frequently collaborating with practitioners to analyze systemic trends.
