The Conference That Grew Up With the Industry

The International Mass Timber Conference turns ten this year. I've been watching this industry evolve for a long time, and the shift from niche material curiosity to serious institutional conversation has been remarkable. Portland, March 31 through April 2. Over 3,000 attendees, 200+ exhibitors, and 60+ sessions across five tracks.

But I'm not going to IMTC to browse. I'm going with specific questions, and most of them sit at the intersection of construction systems, capital structure, and project risk. That's where the real tension lives in mass timber right now, and it's where most of the agenda's strongest sessions land.

Here's what I'm paying attention to and why.

The Boardroom: Developers Pitching Real Projects to Real Capital

This is the session I'm watching most closely.

On Tuesday afternoon, developers will pitch actual mass timber projects to investors in front of a live audience. Not hypothetical case studies. Not renderings with optimistic pro formas. Real deals, real capital, real questions.

This matters because mass timber's biggest constraint right now isn't structural engineering or code compliance. It's capital confidence. Institutional investors still treat mass timber as a novelty in many markets, and developers have struggled to underwrite it with the same confidence they bring to conventional systems.

The Boardroom will reveal how developers are framing mass timber risk for capital allocators. Are they leading with sustainability narratives or with schedule and cost discipline? Are they stress-testing their underwriting or leaning on base-case assumptions? The answers will tell you a lot about where the industry actually stands versus where the marketing says it is.

I've written about the gap between capital structure and development timelines extensively: Stress-Tested Investing for Institutional Capital → Long-Duration Real Estate Capital Durability →

The Insurance Question Nobody Is Answering Well Enough

Here's a topic I wish had its own session at IMTC: insurance.

The insurance market for mass timber remains one of the most underexamined risk factors in the industry. Developers are designing and building mass timber projects while the insurance and underwriting community is still figuring out how to price them. Carriers are inconsistent. Some treat mass timber like heavy timber with favorable rates. Others treat it like an unproven system and price accordingly. A few won't touch it at all.

This creates a disconnect that shows up late in the development process, often during financing. A lender requires a specific insurance structure. The developer discovers the available coverage is more expensive or more restrictive than they modeled. The pro forma shifts. Sometimes the deal shifts with it.

Fire protection is part of this, but it's not the whole story. Duration of construction, moisture exposure during erection, and the limited claims history for mass timber buildings all factor into how carriers assess risk. And because the insurance market moves slower than the construction market, developers are building faster than the risk transfer mechanisms can keep up.

If you're at IMTC and you work in insurance or risk management for mass timber projects, I want to hear what you're seeing. This is a conversation the industry needs to have more openly.

Making Mass Timber Financially Feasible

Thursday morning, Track 4. Presented in partnership with the ULI Mass Timber Council.

This is the session that will separate the optimists from the operators. Financial feasibility in mass timber is still a live question in most markets. Material costs, connector detailing, insurance, fire protection, hybrid structural systems: each one adds complexity to the pro forma, and most developers are still learning where the real cost drivers sit.

What I want to hear is whether the conversation has moved past "mass timber costs more but tenants pay a premium" and into actual cost discipline. Are teams achieving cost clarity through early manufacturer engagement and integrated delivery, or are they still discovering budget surprises during construction documents?

The answer matters for anyone trying to scale mass timber beyond one-off trophy projects.

Achieving Cost Clarity and Early Manufacturer Engagement

Two sessions on Wednesday and Thursday tackle this from different angles. "Achieving Cost Clarity for Mass Timber Projects" runs Wednesday morning in Track 2. "Engaging Mass Timber Manufacturers Early to Improve Cost Certainty and Constructability" runs Thursday afternoon in Track 3.

These are the sessions where the construction reality meets the development pro forma. In my experience, the projects that struggle with mass timber aren't the ones that chose the wrong structural system. They're the ones that engaged the supply chain too late, locked in design decisions before understanding fabrication constraints, and treated the mass timber manufacturer like a commodity supplier rather than a design partner.

Early engagement isn't just a best practice. It's risk management.

But there's a deeper issue here that I think gets overlooked: construction sequencing. Mass timber changes the sequencing logic of a project in ways that most teams don't fully account for until they're in the field. The erection sequence is faster, but it front-loads coordination requirements. Enclosure has to follow structure more quickly because exposed timber can't sit in weather the way a concrete frame can. MEP rough-in has to adapt to a structural system with different penetration constraints.

When sequencing isn't planned around the material system, you get schedule gaps, trade stacking, and rework. Those aren't construction problems. They're planning problems. And they show up in the pro forma as cost overruns.

This is central to how we approach delivery at Evolve Development Group. We plan the construction sequence around the enclosure and structural system before we finalize design, not after.

Moisture Management: The Enclosure Question Nobody Wants to Ignore

Wednesday morning, Track 3. "Moisture Management in Mass Timber: Planning, Protection and Response."

This is building science, not marketing. And it's one of the most important technical conversations happening at the conference.

Mass timber is hygroscopic. It absorbs and releases moisture. If you don't control the enclosure environment during construction and operation, you introduce durability risk that no amount of structural engineering can solve. I've seen projects where the timber was beautiful at installation and compromised within two years because the moisture strategy was an afterthought.

This connects directly to how I think about enclosure performance as a development risk variable. The enclosure is not a finish. It's the primary control layer for heat, air, water, and vapor. Get it wrong and the long-term asset performance degrades regardless of what the structure is made of.

I've written about this in detail: The Importance of the Building Enclosure →

Also Worth Watching

The agenda is deep this year, and several other sessions connect to the themes above even if they aren't where I'll spend most of my attention.

Kengo Kuma's keynote ("Buildings That Breathe," Wednesday morning) is the design event of the conference. Kuma treats wood as a living system, not a decorative choice. What I'm listening for is how he thinks about the relationship between architectural ambition and long-term durability, because the best mass timber projects are the ones where the structural system, enclosure strategy, and architectural expression all work together rather than pulling in different directions.

Amazon and Meta's keynote (Thursday morning) matters for scale logic. When companies operating at that level commit to mass timber, they're stress-testing fabrication capacity, procurement timelines, and delivery systems at volumes that reveal supply chain constraints the rest of the industry hasn't encountered yet. Whether they're expanding or hedging tells you something real about where supply chain maturity actually stands.

Affordable housing (Wednesday morning, Track 1) is where the industry's aspirations meet its economics. The question isn't whether mass timber can be used in affordable housing. It can. The question is whether it can be delivered at cost parity with conventional systems in a way that makes it the rational choice rather than the aspirational one. If mass timber is going to matter for housing at scale, that cost conversation has to get more honest. I've written about the structural forces constraining housing supply in Housing Shortage as a Systems Failure and Misaligned Capital Flows.

Mass timber in medical and health spaces (Thursday morning, Track 1) is interesting because healthcare is one of the most demanding building typologies. If mass timber can meet infection control, air quality, acoustic, and durability requirements in that environment, it can meet them anywhere. The convergence of biophilic design research with material choice is worth tracking. More on this in Healthy Buildings: Why Indoor Air Quality Drives Real Estate Value.

Industrialized Construction: The Real Scalability Question

Two sessions on Wednesday afternoon map the spectrum of industrialized mass timber, and together they tell a more important story than either one does alone.

"From Custom to Production" in Track 1 has five builders discussing the transition from one-off mass timber projects to repeatable, production-scale delivery. "From Panel to Pod" in Track 2 presents case studies across the prefabrication continuum, from panelized CLT and MPP systems to fully finished volumetric modules.

This is the conversation I care about most at the conference. And it's the one where the industry has the most work to do.

The panelized question. Panelized mass timber, flat CLT or mass plywood panels shipped to site and erected with a crane, is the most mature form of mass timber prefabrication. The economics are understood. The erection sequences are well documented. The constraint isn't whether it works. It's whether it can be standardized enough to drive costs down through repetition. That means standard panel dimensions, predictable connection details, and design processes that accommodate fabrication constraints from day one rather than resolving them in shop drawings.

The volumetric question. Volumetric modular mass timber, factory-finished room-scale units with MEP, finishes, and fixtures installed before they ship, is the more ambitious play. The theoretical advantages are significant: compressed schedules, controlled factory environments, less site labor. But the integration challenges are real. Tolerance stacking between mass timber structure and modular infill creates detailing problems. Moisture management during transportation and storage adds risk. And coordinating factory production timelines with site-erected structure requires sequencing discipline that most project teams haven't developed.

The automation and AI question. What I don't see on the agenda, and what I think IMTC needs to address more directly, is the role of factory automation and AI-driven fabrication in making industrialized mass timber economically viable. CNC fabrication of mass timber panels is already standard. But the next generation of manufacturing, robotic assembly of wall and floor cassettes, automated quality inspection, AI-optimized cutting patterns to reduce material waste, is where the cost curve actually bends.

The builders who figure out how to move from craft production to systems production will define the next decade of this industry. I want to hear whether the teams on these panels are thinking at that level, or whether they're still solving problems one project at a time.

This connects to a broader thesis I've been developing about construction productivity and the physical constraints on housing delivery: Construction Productivity: Unlocking the Physical Ability to Build at Scale → Why Construction Labor Productivity Has Declined Since 1970 →

Supply Chain Resilience

Thursday morning, Track 2. "Supply Chain Resilience: Forests, Markets, and Mass Timber."

The supply chain conversation is where long-term industry viability gets tested. Mass timber's growth has been constrained by fabrication capacity, fiber supply, and transportation logistics. As demand scales, the question is whether the supply chain can keep pace without introducing the kind of lead-time volatility that makes mass timber uncompetitive with conventional systems.

For developers, supply chain risk is duration risk. If your mass timber procurement adds three months to the schedule because of fabrication backlog, that's three months of additional carry cost. And in a rising rate environment, that carry cost erodes returns faster than most pro formas assume.

This is why I treat construction system selection as a capital allocation decision, not just a design decision: Mass Timber Risk Strategy → Mass Timber and Duration Risk →

What I'm Really Looking For

IMTC has matured from a materials conference into a development and systems conference. That's the right evolution. The technical questions about mass timber are largely answered. The structural engineering works. The fire performance data is strong. The code pathways exist.

The questions that remain are operational and financial. Can you build it at cost parity? Can you insure it without blowing up the pro forma? Can you sequence it without field surprises? Can you procure it on a predictable timeline? Can you industrialize it beyond one-off projects? Can you underwrite the risk with the same confidence you bring to concrete and steel?

Those are the questions I'm bringing to Portland. And they're the same questions that run through everything I write about development systems, capital discipline, and construction delivery.

If you're attending IMTC and want to talk about mass timber from a development risk perspective, find me. That's the conversation I'm most interested in having.

Frequently Asked Questions

What is the International Mass Timber Conference? IMTC is the largest mass timber event in the world, held annually in Portland, Oregon. The 2026 conference marks its tenth year, with 3,000+ attendees, 200+ exhibitors, and 60+ sessions covering design, construction, development, manufacturing, and supply chain across five focused tracks.

Why does mass timber matter for real estate development? Mass timber offers potential advantages in construction schedule, carbon performance, and occupant experience. But it also introduces procurement, cost, and durability risks that differ from conventional systems. The development case for mass timber depends on whether teams can manage those risks with the same discipline they apply to concrete and steel.

What are the biggest risks in mass timber development? The primary risks are cost certainty, supply chain lead times, moisture management during construction, insurance and fire protection requirements, construction sequencing complexity, and the limited availability of experienced erection crews in many markets. Each of these risks compounds across longer development timelines.

Why is insurance a challenge for mass timber projects? The insurance market for mass timber is still catching up to the construction market. Carriers vary widely in how they price mass timber risk, and some won't underwrite it at all. This creates uncertainty that typically surfaces late in the development process, often during financing, when coverage gaps or unexpected premiums can shift project economics.

How does construction sequencing differ in mass timber? Mass timber front-loads coordination requirements compared to conventional systems. Structure goes up faster, but the enclosure has to follow closely because exposed timber can't tolerate prolonged weather exposure the way concrete can. MEP rough-in adapts to different penetration constraints. Teams that don't plan the construction sequence around the material system tend to encounter trade stacking, schedule gaps, and preventable rework.

How should developers evaluate mass timber as a structural system? Developers should treat structural system selection as a capital allocation decision. This means evaluating mass timber against schedule risk, procurement timeline, cost predictability, enclosure integration, and long-term asset durability rather than choosing it based on sustainability marketing or aesthetic preference alone.

Is mass timber cost-competitive with conventional construction? In some markets and building types, mass timber is approaching cost parity with conventional systems, particularly when schedule savings and reduced site labor are factored in. In other markets, it remains a premium choice. The cost picture is evolving rapidly as fabrication capacity expands and design teams gain experience with the system.
