The Risk Isn't the Material

I need to say something that the mass timber industry doesn't want to hear.

When timber projects fail, the timber isn't the problem. Not once have I looked at a troubled mass timber deal and thought, "the CLT didn't perform." The panels are engineered. The fire testing is extensive. The code pathways exist and keep expanding. That debate is settled.

What isn't settled is whether development teams know how to plan around the system. And in my experience, most don't. At least not yet.

The projects I've watched struggle, and I include some of my own work in that category, didn't break because someone picked the wrong material. They broke because the team introduced timber without rethinking the coordination sequence, the institutional alignment, or the procurement timeline. The material was fine. The process around it wasn't.

I don't write about this from a distance. I've had projects go sideways because of poor execution sequencing. Not mass timber projects, but complex high-performance builds. Net zero passive house work. The kind of detailed building science that demands precision at every layer of the enclosure. The buildings were exceptional. But I brought in too many voices trying to make things perfect instead of executing decisively, and the timelines stretched past what the capital structure could absorb. That experience shapes everything I think about sequencing, governance, and capital alignment now, regardless of the structural system. I've written about the broader pattern in Development Risk in Real Estate on the Durata Advisory site.

Mass timber sharpens all of these risks. It doesn't create new ones. It just punishes sloppy coordination faster than concrete or steel would.

Why Sequencing Hits Different With Timber

I explored the relationship between time and capital performance in Mass Timber and Duration Risk in Long-Cycle Development. The core argument: when schedule extends, IRR compresses. Doesn't matter what the structure is made of. Time is the variable that kills returns.

But timber has specific sequencing characteristics that most teams underestimate. I'll walk through three of them because I've seen each one create problems on real projects.

The speed trap. CLT goes up fast. Significantly faster than cast-in-place concrete. Developers love hearing that. What they don't hear, or don't internalize, is that fast erection front-loads every coordination requirement on the project. The trades have to be ready to follow the structure at the pace it goes up. If they're not? You get gaps. Dead time on site with a structure standing and nobody working on it because the next scope wasn't mobilized. The framing crew finishes in six weeks and the MEP rough-in team isn't scheduled for another month. That kind of thing.

I've seen teams lose most of the schedule advantage timber gives them because they planned the trade sequence around a conventional pace and then couldn't accelerate when the structure went up ahead of schedule. The speed becomes a liability when nobody downstream is ready for it.

The weather clock. Concrete can sit in rain for weeks. Nobody likes it, but it survives. Timber can't. Exposed CLT and glulam absorb moisture, and if they stay wet too long you've got a durability problem that shows up years later. Warping. Mold behind finishes. Callbacks that erode NOI.

This means the enclosure has to chase the structure. Not eventually. Immediately. The waterproofing, the air barrier, the cladding support, all of it has to be sequenced as part of the structural plan, not treated as a separate scope that starts whenever the enclosure sub shows up. Durata Advisory examines this dynamic in Building Enclosure Risk in Development. It's one of the most underappreciated risk factors in timber construction.

The penetration problem. Mass timber panels aren't poured around conduit and pipe sleeves the way a concrete deck is. You can't easily core through a CLT panel after the fact without compromising structural capacity. MEP routing has to be coordinated with the panel layout during design, not resolved in the field during rough-in. When it isn't, you get rework. Change orders. Delays that cascade.

None of this is the timber's fault. It's planning. And every bit of it is preventable if the construction sequence is designed around the material system before design is finalized. I've explored this across project types in Construction Sequencing in Complex Development and Why Project Timelines Determine Execution Success on the Evolve site.

This is how we approach delivery at Evolve Development Group. Sequence first. Then design. Not the other way around. Because I've learned the hard way what happens when you let the design process drive the schedule instead of the other way around. Development outcomes are largely determined before construction begins, as I've written on the Durata Advisory site. By the time you're in the field trying to fix a sequencing problem, you've already lost.

The Institutional Alignment Problem

Here's something that surprises people who haven't done a mass timber deal: some of the biggest schedule risks have nothing to do with construction. They happen in conference rooms. Insurance underwriting meetings. Credit committee reviews.

When a development team introduces mass timber late in the process, every institutional stakeholder reacts instead of aligns. The insurer sees an unfamiliar system and either prices in a fat uncertainty premium or just says no. The lender's credit committee wants a tutorial on fire performance before they'll approve the loan. Third-party reviewers expand their scope because they haven't seen enough timber projects to know what to look for.

All of that takes time. And time is money. Literally, in development finance.

I've watched projects lose three to six months to this kind of friction. Not because anyone was being unreasonable. The questions were legitimate. But they surfaced at exactly the wrong moment, during underwriting, when every week of delay adds carry cost to the capital stack. It's a specific version of the broader design-execution coordination gap that undermines projects across structural systems.

The fix isn't complicated. It's just early.

Engage your insurer during schematic design, not during the financing package assembly. Bring fire engineering documentation to the first conversation, not the third. Give the lender's credit committee reference projects and third-party data before the loan application hits their desk. Let them get comfortable on their timeline, not yours.

When you do this, timber becomes a known quantity. When you don't, it becomes a variable that triggers review cycles and extension requests and that slow drip of carry cost that quietly erodes your returns.

At Durata Advisory, this is part of what we help development teams structure. The institutional alignment process. Getting insurers, lenders, and reviewers comfortable with the system before the capital clock starts running.

Procurement Is Not a Logistics Problem

I'll say it plainly: if you think mass timber procurement is a construction issue, you're going to get hurt.

It's a capital timing issue. Full stop.

Here's why. Fabrication capacity for CLT, glulam, and mass plywood panels is finite. There are a limited number of fabricators. Lead times shift based on demand cycles, regional capacity, and how many other projects got in line before yours. You can't call up three suppliers and get competitive bids by Friday the way you can with rebar.

These panels are fabricated to your specific dimensions, often by a single manufacturer, with lead times measured in months. Sometimes many months.

So when procurement isn't locked early, the dominoes fall in a predictable sequence. Fabrication slots get committed to other projects. Your lead time extends. Material costs creep because you've lost leverage. The construction schedule shifts. And that schedule shift cascades into financing costs, contractor repricing, and the kind of investor return compression that turns a good deal into a mediocre one. This is exactly the gap between feasibility assumptions and construction reality that I examine in Feasibility Models vs. Construction Reality on the Durata Advisory site.

I wrote more about this in Mass Timber Procurement Strategy on the Evolve site.

Duration control is capital discipline. They're the same thing. And procurement is where that discipline either holds or doesn't.

What a Structured Risk Strategy Actually Looks Like

I've spent a lot of words describing what goes wrong. Here's what going right looks like. Four things, all before construction starts:

Talk to your insurer during schematic design. Not when the lender asks for a certificate. During schematic. Bring the fire engineering, the enclosure details, the moisture management plan. Give them room to evaluate, ask questions, and get to yes without a deadline breathing down everyone's neck.

Commission fire engineering early. Mass timber fire performance data is strong, but it has to be project-specific. Generic test results don't satisfy most institutional underwriting. Get the analysis done during design, not as an emergency addendum during permitting when everyone's already stressed.

Educate your lender before you apply. If the credit committee hasn't seen a timber deal, they will ask questions. Good questions. But those questions during underwriting means weeks of delay. Prepare materials, pull reference projects, assemble third-party data, and walk them through it before the application goes in.

Lock procurement before design development. Secure your fabrication slot and pricing early. This does three things at once: it stabilizes the schedule, it protects your cost assumptions, and it takes the single largest source of schedule volatility off the table.

When all four of these land, timber gives you a genuine edge. Faster structure. Less site labor. Factory-controlled quality. Compressed timelines that improve capital performance. That's what we detail in High Performance Buildings on the Evolve site.

When they don't land, the same material introduces friction that concrete wouldn't have. Not because timber is riskier. Because the team wasn't ready.

What I've Learned About Risk

I'll close with something personal.

I used to think risk in development was mostly about market timing and financial structure. Pick the right market, get the right capital stack, and execution would take care of itself. I was wrong.

The projects that taught me the most weren't mass timber. They were complex high-performance residential builds. Net zero energy. Passive house certified. Luxury work where every detail of the enclosure, the mechanicals, the finishes had to be right. And the buildings were right. They were some of the best work I've been involved with. But I let the pursuit of perfection override the discipline of execution. Too many stakeholders with opinions. Too much refinement when what was needed was decisiveness. The governance wasn't tight enough, and the timelines stretched past what the capital structure could support.

I bring that experience to mass timber because the risk pattern is the same. Different material, different technical details, but the same fundamental failure mode: coordination breakdown and capital misalignment compressing around a team that's still trying to perfect the product instead of delivering it.

That's why, when I look at mass timber risk, I don't see a material problem. I see a coordination test. The developers who pass it are the ones who plan the sequence, align the institutions, lock procurement, and resist the temptation to keep perfecting things when what's needed is to build.

The ones who don't tend to learn the same lesson I did on different projects: the building wasn't the problem. The process was.

Frequently Asked Questions

Is mass timber inherently riskier than concrete or steel? No. When I look at troubled mass timber projects, the issue is almost always late coordination with insurers, lenders, and procurement teams. The material performs. The question is whether the team around it planned for the specific coordination requirements timber introduces. When they do, timber can actually reduce overall project risk through faster erection and factory-controlled fabrication.

Why do lenders hesitate on mass timber projects? Usually because the development team introduced timber late in underwriting. Credit committees are being asked to evaluate an unfamiliar system under time pressure, which is an uncomfortable position for anyone approving a loan. The fix is early education: reference projects, fire engineering data, and third-party performance documentation presented before the loan application goes in.

How does sequencing affect IRR in mass timber development? Directly. If procurement and institutional alignment get delayed, the construction schedule extends. Extended schedules mean more months of carry cost on development financing. I've seen three to six month delays on leveraged deals meaningfully erode investor returns even when the project ultimately delivered on budget. The building was fine. The timeline killed the economics.

When should insurers be engaged on a mass timber project? During schematic design. Not during financing. Not during permitting. During schematic. Early fire engineering documentation and a construction moisture management plan let insurers evaluate the project on its merits. Late engagement forces them to price uncertainty, and uncertainty always costs more than information.

Is procurement a construction issue or a capital issue? Capital issue. Every time. Mass timber fabrication capacity is limited, lead times run months, and panels are project-specific. Late procurement means longer lead times, higher costs, and schedule shifts that flow straight into your capital exposure. I think of procurement timing as the single most controllable variable in mass timber project risk.
