Blockchain and Smart Contracts for Sustainable Asset Management in Construction

Introduction

The role of blockchain in construction lifecycle management is evolving from hype to real-world impact. While the buzz often feels split—either overly technical or full of buzzwords—there’s a deeper shift underway. These technologies aren’t just tools for improving workflows; they’re challenging the way we think about trust, responsibility, and the long-term value of the built environment. If you’re working in construction, or researching it, you’ve probably come across the terms “blockchain” and “smart contracts” already. But what do they really mean in practice? And how might they reshape the way we manage assets—not just during handover, but years into a building’s operation? This piece tries to unpack some of that, with a focus on what’s actually worth investigating further.

Blockchain and Smart Contracts—What They Represent, Not Just What They Are

There’s been plenty written about blockchain as a “decentralised ledger” and smart contracts as “self-executing code.” While these definitions are technically accurate, they don’t quite capture why construction researchers and professionals are paying closer attention. At its core, blockchain creates a shared space for information—one where records, once entered, can’t be modified without consensus. That permanence, while technical in nature, also speaks to issues of trust, accountability, and governance.

Smart contracts, on the other hand, represent more than just automation. They are, in essence, decision rules embedded in code. When certain conditions are met—say, a delivery is confirmed, or a milestone is achieved—they trigger actions automatically. In a sector where delays, miscommunications, and disputes are common, the idea of rules being applied impartially and instantly is understandably compelling. But it also raises deeper questions: what if those rules are wrong? Who wrote them? Who benefits?

Blockchain in Construction Lifecycle Management: Beyond Silos and Snapshots

In many construction projects, asset data is fragmented. Design lives in one system, procurement in another, and maintenance logs in a third. Over time, it becomes difficult—even impossible—to reconstruct an accurate picture of what happened, when, and why. This isn’t just a technical failure; it’s a problem of institutional memory.

Blockchain offers an alternative model. If project data—from property transfers to inspection dates—is recorded sequentially in a single, shared system, the result isn’t just better records. It’s a foundation for real-time decision-making and long-term accountability. Imagine being able to review the full history of a bridge’s construction and upkeep with a few clicks, or to prove that sustainably sourced materials were indeed used in a building project. The potential here is less about “tech” per se and more about changing how we build and maintain trust over time.

Trust, Disputes, and the Politics of Verification

If you’ve ever worked on a construction site—or managed a project—you know how quickly things can get messy when trust breaks down. Delays happen, paperwork gets lost, and more often than not, everyone has a different version of events. Blockchain promises a kind of digital paper trail that’s shared by all and edited by none. Sounds great, right? But the real story is more complicated. Sure, it could help reduce finger-pointing when things go wrong. But it also changes how verification happens—and who controls that process. Is that always a good thing? Maybe. Maybe not. These are the kinds of questions researchers should be asking.

Automation and Its Discontents

On paper, smart contracts sound like the perfect fix for construction delays. Milestone reached? Trigger a payment. Inspection passed? Release the next tranche of work. But as anyone in this field knows, real-life projects aren’t that clean. Sometimes rules need to bend; sometimes what’s fair isn’t what’s written. So while automation might help reduce disputes, it also takes decision-making out of human hands. That raises a few important questions. Who gets to define the conditions in these contracts? Can we ever make automated decisions feel “fair”? And what happens when the software says yes, but the site says no?

Rethinking Sustainability: From Reporting to Verification

Sustainability has become a central theme in construction discourse. Yet, despite an abundance of ESG frameworks and carbon calculators, many sustainability claims are still difficult to verify. Blockchain could provide the infrastructure for more credible reporting.

Consider a scenario where every batch of steel used in a project comes with a digital token, proving its environmental origin. Or where building energy performance is continuously monitored and recorded. These ideas aren’t futuristic; they’re being tested. But their real power lies not in novelty, but in their ability to embed sustainability into the operational core of projects, rather than leaving it on the periphery.

Projects and Pilots: Early Signals

We’re already seeing some governments and companies take blockchain out of theory and into practice. Dubai’s real estate system is experimenting with digitised land transactions. The UK is looking at blockchain for infrastructure oversight. And in China, it’s being used to trace materials in massive construction projects. These pilots are interesting—not just for what they achieve, but for what they reveal. What kind of political and regulatory environments allow these ideas to take root? And what lessons can other regions take from them, especially when the context is totally different?

Research Opportunities in Blockchain for Construction Lifecycle Management

For postgraduate and doctoral students, blockchain offers more than a trendy topic. It presents a multidisciplinary challenge. Those in computer science might explore system design or security. Students in construction management could study procurement models or smart contract compliance. Scholars of law, ethics, or public policy might focus on data ownership or the unintended consequences of automation.

Some pressing questions include: How can blockchain be integrated with BIM or digital twin technologies? What governance frameworks support equitable use of smart contracts? How does automation affect labour dynamics and professional accountability?

Concluding Thoughts

Blockchain and smart contracts are not panaceas—but they are signals of a deeper shift. They invite us to reconsider how knowledge is produced, shared, and preserved in construction. And they offer researchers an opportunity not just to critique or adopt them, but to help shape their development in more inclusive, thoughtful, and sustainable ways.

For the academic community, this is a space wide open for exploration. The next wave of innovation will not be led by code alone—but by those who ask better questions.
