Bill Seery of Consigli Construction argues that construction should become an assembly of parts, starting with single-trade prefab on every job. He points to repeatable owner playbooks, like healthcare networks, as the way past one-off projects.

How Bill went from industrial engineering in medical devices to co-founding what he says was the first US manufacturer of modular bathroom pods, about 20 years ago.

His case for single-trade prefab on every job, built around a warehouse tote labeled for each hotel room with everything pre-wired and pre-tagged.

Why comparing a prefabricated medical headwall with one built in place means pricing schedule, quality, safety and contingency, not just the part.

His bike-riding analogy for why firms avoid new methods: the first panelized facade might deliver 60 to 70% of the value, but the third or fourth pays off.

How healthcare networks are building the same ambulatory surgical center from a standard playbook, with bath pods, headwalls and facades already priced.

What he thinks will never change: construction is still the interface of putting something new on a piece of land, with new variables every time.

There's no reason not to be doing single-trade prefabrication on every project, on almost any scope.

Chapters

From medical devices to bath pods

Bill's route from manufacturing into construction, and what industrialized construction means next to building in place.

Pricing prefab against in-situ work

How Revit and as-built scanning helped prefab fit the job, and what to count when comparing a prefab headwall with one built on site.

Crawl before you walk

Single-trade prefab as the starting point, the harder multi-trade work, and the GC's job in preconstruction and with its subs.

Prefab and the housing shortage

Why he is excited about ADUs and a fast, non-combustible cold-formed steel system for dense urban housing.

Why the industry holds back

Lack of understanding, siloed architects and CMs, and an industry that will not pay for a first attempt.

Playbooks, not projects

Healthcare networks building from a standard kit of parts, and what he expects AI and the cloud to change.

This is the largest industry in the world that has no R&D budget.

Takeaways

There is no reason not to do single-trade prefab on almost every project, such as kitting each room's electrical in a labeled tote back at the warehouse.

Comparing prefab to in-situ work means pricing schedule, quality, safety and contingency, not just the unit cost of the part.

Owners siloing architect and CM from day one blocks design for manufacturing, unlike Toyota, which keeps design and manufacturing engineers together.

Construction is the largest industry with no R&D budget, and teams reject new methods because the first attempt might only deliver 60 to 70% of the value.

Healthcare networks building the same surgical centers from a standard kit of parts show what repeatable partnerships can do, and copycats will follow.

Never underestimate the value of copycat, because once somebody's proved out that it can work, everybody else will pile in.
