Advances in digital design, data-driven engineering and AI are helping the construction industry move beyond demolition-first thinking, writes Stephen Fernandez, global retrofit leader at Arup
We construct so many new buildings every week that they could create a city the size of Paris, while the construction industry continues to consume around 50% of all raw materials extracted globally.
At the same time, we are still demolishing vast swathes of existing building stock – and that’s despite recognition across the sector that demolition is rarely the most sustainable option.
That contradiction is not driven by ignorance but by a persistent lack of data and visibility. The scale of the challenge is clear: 10% of the world’s 40,000 tall buildings are nearing the end of their originally intended design life and are likely to face demolition, even though they remain structurally sound and adaptable.
At Arup, our new Reuse Playbook sets out to tackle one of the sector’s most persistent barriers: uncertainty over the performance and reuse potential of existing structures and reclaimed materials. The guidance gives developers, designers, contractors and insurers a practical roadmap for bringing more materials back into circulation and reducing the amount sent to landfill.
Critically, advances in digital design, data-driven engineering and AI are helping the industry move beyond demolition-first thinking by making reuse decisions more
measurable, reliable and commercially viable.
From uncertainty to decision ready scenarios
For developers and investors, a decision-ready solution depends on two fundamentals: a credible understanding of an asset’s condition and clear visibility of possible scenarios at controlled risk.
Historically, asset audits have struggled to support with scattered information across PDFs, spreadsheets and legacy records. Digital assessment, immersive 3D modelling and AI analytics are changing that dynamic by consolidating survey data, testing results and engineering judgement into integrated models that teams can interrogate early, comparing reuse and retrofit options before designs are locked in and costs crystallise.
In the UK, this approach has been demonstrated at Euston Tower, where advanced structural testing and AI enabled analysis were applied to assess in situ concrete slabs for reuse as new “precast” elements, enabling one of the earliest large scale examples of structural concrete reuse. Crucially, it showed how unknowns can be transformed into testable, investable scenarios, rather than defaulting to demolition.
Material transparency in a tightening regulatory environment
Designing and managing buildings sustainably now means keeping pace with tightening carbon standards and material related compliance across jurisdictions. In Australia, this is already playing out through planning frameworks and tools such as NABERS Embodied Carbon, while globally the EU has moved further with Digital Product Passport requirements designed to make information on material composition, environmental impact, reusability, recyclability and end of life handling more transparent and transferable.
The global momentum is pointing to the same need: the reliable, transferable data on what materials exist within buildings, how they perform and how they can be reused. A Digital Material Passport provides a live foundation, enabling materials to be tracked, managed and valued over time rather than written off when standards change.
Sydney’s Quay Quarter Tower, widely recognised as the world’s first upcycled skyscraper and an Earthshot Prize finalist, illustrates what this makes possible.
The project preserved 98% of the existing structural walls and core, retained 65% of the original structure and saved more than 12,000 tonnes of embodied carbon, demonstrating how digital material intelligence can support both ambitious sustainability outcomes and increasingly rigorous carbon-led compliance.
Technology enables functioning marketplace
Digitally enabled material data, from testing evidence to live material records, allows reused components to be described consistently, priced accurately and matched to future demand. By creating a common data layer between supply and demand, digital platforms enable reused materials to enter mainstream procurement rather than bespoke, one-off decisions.
Only when reuse is supported by market mechanisms, not just technical feasibility, can it move from individual projects into repeatable, commercially viable practice.
A clear guide to collaborate
With stronger data and clearer market pathways, reuse cannot be delivered by any single party acting alone. Asset owners, designers, engineers, contractors, insurers and material specialists all shape outcomes, yet reuse repeatedly stalls when these groups work to different assumptions and timelines.
Digital tools can help establish a shared evidence base, but delivery still depends on shared understanding of roles and expectations. This is where the Reuse Playbook plays a practical role as a guide to collaboration. By clarifying who needs to act, when key decisions should be made and what level of evidence is required at each stage, it helps teams align technical, commercial and risk perspectives.
Reuse as the industry’s new normal
From early asset assessment and scenario testing through to material transparency and regulatory compliance, technology is turning circular construction from an aspiration into a decision ready, investable proposition.
Demolition has long been favoured because it felt predictable. Better evidence and more structured collaboration are now challenging that assumption. The task is to make reuse the industry’s new normal. That means applying a Total Design approach: bringing together engineers, ecologists, planners, designers and digital specialists from the outset.
In a sector under mounting carbon, material and regulatory pressure, this integrated way of working is no longer optional it must be the default way of thinking.
