What Is Most Important in 2021 Feat. Charlie Dunn

Why Construction Is 230 Years Behind Manufacturing

Most construction projects start the same way. Raw materials arrive at the site. Workers measure, cut, fit, and assemble everything in the field. They work in rain, heat, cold, and unsafe conditions. They bend, reach, and overextend to install components in awkward positions. They coordinate on the fly. They rework mistakes. They generate waste. And when the project finishes, everyone moves to the next site and does it all over again the exact same way. This is not progress. This is repetition. And it is costing the industry productivity, safety, quality, and the ability to attract the next generation of workers.

Here is the uncomfortable truth. Construction is about 230 years behind manufacturing. Manufacturing had its industrial revolution in the late 1700s and early 1800s when standardized interchangeable parts enabled assembly lines, automation, and focused study. Construction has not had that revolution yet. We are still adapting the worker to the work instead of adapting the work to the worker. We are still treating every project like a prototype instead of leveraging design reuse and standardization. And we are still defaulting to stick-building everything on site when prefabrication could solve most of the problems we complain about daily.

The failure pattern is predictable. Teams wait until design is 100 percent complete. Then they reverse engineer it, break it apart, and try to figure out how to build it. Sometimes they do a halfway decent job of that planning. Sometimes they are in the field trying to figure it out while the clock is running. Either way, the default assumption is that everything will be built stick by stick on site. And prefabrication, if it happens at all, is treated as the exception. A nice-to-have. An innovation. Something you consider if you have extra time or budget. This is backwards. Prefabrication should be the default. And stick-building should be the negotiated exception.

I worked on a research laboratory project where we prefabricated everything we could. We prefabricated all of the overhead MEP in spools on the first two floors around priority walls that were 80 percent complete. We pre-cut all of the studs, box headers, jams, and stud lengths. Everything came out pre-cut. We had drastically reduced waste. We did room kitting inside where we had people prefabricate the interiors. And when I look back on that project, prefabrication was the best thing we did. Not just because it improved safety and quality. But because it vetted the design issues earlier. If we could not build it on paper and prefabricate it in the shop, then we never had the right information to build it in place in the field. We were missing a dimension or a coordination issue or something else. Prefabrication pre-vets the design before it becomes a schedule impact. And it takes the work out of the chaotic field environment and puts it into a controlled environment where standard work, safety, and quality can actually be managed.

Why Prefabrication Matters More Than You Think

Prefabrication is not just about moving work offsite. It is about fundamentally changing the presumption of how construction happens. And there are three reasons why this shift matters more than most people realize. The first is empathy. The second is production design. And the third is design reuse. Together, these three shifts will create more value for construction over the next decade than any other innovation. And prefabrication is the engine that makes all three possible.

Empathy means beginning with the worker in mind instead of adapting the worker to the work. Construction has traditionally forced workers into unsafe conditions, awkward positions, and congested environments. Workers bend, reach, and overextend because that is just considered part of the challenge. But with prefabrication, we can adapt the work to the worker. We can create safe environments. Well-lit environments. Decongested environments. And we can provide super clear visual explanations like we are used to seeing in other industries. This is not just about being nice. This is about recognizing that the future of construction capital is threatened if we cannot grow the workforce, create excitement about the industry, and create safer and more inspiring working conditions. Vertically integrated owners with large portfolios of projects are starting to demand this. They are saying they will not accept the kind of safety numbers on construction sites that they would never tolerate in their manufacturing facilities. And prefabrication is one of the primary tools that enables that shift.

Production design means designing the building with the end in mind. In other industries like automotive or home appliances, you would never design a new product without strategically knowing how you plan to build it. But in construction, this is foreign. We get 100 percent design and then reverse engineer it to figure out if we can build it. Production design flips that. It starts with understanding what the supply chain can do, what factories can do, and what the workforce can do. And it designs the building with production design principles so that it can be delivered safely, with high quality, and with good productivity. This requires designers and builders to work together earlier. It requires integrated delivery methods. And it requires a mindset shift from designing in isolation to designing with production in mind.

Design reuse means not starting from zero on every project. Right now, every project goes through the same long runway of design, price, redesign, coordinate, price, and redesign. And that cycle repeats on every single project even when the building type is the same. Data centers, healthcare MOBs, pharmaceutical plants, and other building types with repetitive programs are still designed from scratch every time with different designers, different design components, and different coordination processes. This is wasteful. What if we could get to 70 percent design reuse? What if vertically integrated owners could say here is our standard design for this building type and we are only customizing the last 30 percent? That would eliminate years of rework. It would reduce chaos in the field. And it would allow teams to focus on the unique aspects of the project instead of reinventing the wheel every time. If your project needs superintendent coaching, project support, or leadership development, Elevate Construction can help your field teams stabilize, schedule, and flow.

Signs You Are Stuck in the Old Default

Here are the signals that your team is still defaulting to stick-building instead of prefabrication:

• You reverse engineer the design after it is 100 percent complete instead of planning production during design
• Workers are bending, reaching, and working in unsafe or awkward positions because that is just how the work has to be done
• You generate significant waste from cutting materials on site instead of pre-cutting in a controlled environment
• Design issues and coordination problems surface in the field instead of being caught during prefabrication planning
• Every project feels like a prototype instead of leveraging standardization and lessons learned from previous projects
• Prefabrication is treated as an innovation or exception instead of the default approach
• You assume everything will be stick-built unless someone makes a compelling case for prefab

These patterns are not inevitable. They are choices. And they can be changed by shifting the default assumption.

How to Shift the Default

Changing the presumption from stick-building to prefabrication requires intentional effort. It requires leadership to make the case. It requires trade partners to adjust their approach. And it requires designers to think differently about how buildings are designed. Here is how to start. First, change the language. Stop saying we are going to try prefabrication on this project. Start saying everything will be prefabricated unless there is a compelling reason not to. Make stick-building the negotiated exception instead of prefabrication being the innovation. That language shift changes how teams approach planning.

Second, engage the supply chain early. Do not wait until design is complete to figure out what can be prefabricated. Bring trade partners and fabricators into the conversation during design so they can inform what is possible and what needs to be coordinated. This is production design in action. And it requires integrated delivery methods that allow the team to collaborate before the design is locked.

Third, invest in design reuse. If your organization builds the same building types repeatedly, stop designing from scratch every time. Develop standard designs that can be customized for specific sites and user needs. This does not mean cookie-cutter buildings. It means baking in the lessons learned, the coordination, and the production planning so you are starting from 50, 60, or 70 percent instead of zero. The time saved in design and coordination can be reinvested in making the unique aspects of the project better.

Fourth, create the right environment for prefabrication. Lean manufacturing works because the environment supports standard work, visual management, and continuous improvement. Construction has been trying to bring lean to the chaotic field environment. But prefabrication flips that. It brings the work to the controlled environment where lean principles can actually function. Safe, well-lit, decongested spaces with clear visual instructions enable workers to do better work faster with less waste.

Fifth, push through resistance. Some people will resist prefabrication because it requires them to think differently, plan earlier, and coordinate more intentionally. Do not let that resistance stop progress. As one lean manufacturing leader said when asked what to do when trade partners resist the plan, you whip them in the ass. That is not about being cruel. It is about being firm. Prefabrication will not work if it is optional. It has to be the expectation. And teams need to experience it for six weeks before they can truly choose. Until they have both options in front of them, they cannot make an informed choice. So push it down everyone’s throat until they see how great it is. Then it becomes self-sustaining.

The Challenge

Walk your next project and ask yourself this question. What are we building stick by stick on site that could be prefabricated in a controlled environment? What design decisions are we making without understanding how the building will be produced? What lessons are we learning on this project that we will have to relearn on the next one because we are not capturing design reuse? And what are we doing to our workers by forcing them to adapt to unsafe, inefficient, and chaotic conditions instead of adapting the work to the worker? If the answers to those questions reveal opportunities, you have a choice. You can keep doing what you have always done. Or you can shift the default. Default to prefabrication. Make stick-building the exception. And watch what happens when you stop treating every project like a prototype and start building with empathy, production design, and design reuse.

Construction’s industrial revolution is not in the past. It is in the future. And prefabrication is the engine that will get us there. As Charlie Dunne said, “Fall in love with your problems, not your solutions.” The problem is that we are 230 years behind manufacturing. The solution is prefabrication. And the time to shift the default is now.

On we go.

Frequently Asked Questions

Why is construction 230 years behind manufacturing?

Manufacturing adopted standardized interchangeable parts in the late 1700s, enabling assembly lines and automation. Construction still defaults to stick-building everything on site without standardization.

What are the three big shifts prefabrication enables?

Empathy for workers by adapting work to the worker, production design that plans how to build during design, and design reuse that eliminates starting from zero.

How do you overcome resistance to prefabrication?

Change the default assumption so prefabrication is expected and stick-building is the exception. Push through resistance by requiring teams to experience it before choosing.

What is production design?

Designing the building with understanding of how it will be built, including supply chain capabilities, factory capabilities, and workforce capabilities, rather than reverse engineering after design is complete.

What does design reuse mean for repetitive building types?

Starting from 50-70 percent standardized design instead of zero, eliminating the rework cycle of design, price, redesign, coordinate on every project for building types like data centers or healthcare.
