With project starts forecast to rise, the UK construction sector is entering a period of renewed optimism. However, despite this resurgence, some persistent risks continue to quietly erode profitability. Here, Brittany Harris, CEO & Co-Founder of Qflow, explores how adopting the use of smarter data can both protect margins and meet modern demands for quality, compliance, and sustainability.
Delivering more with less – less carbon, less waste, and fewer errors – is fast becoming the benchmark for success in construction. Yet, two disruptive challenges persist: project waste and unmonitored material substitutions. Far from being just environmental headaches or compliance issues, these problems stem from poor-data management and quietly erode profitability, pose serious commercial vulnerabilities, and are capable of destabilising even the most rigorously managed projects.
The hidden danger of fragmented data
Despite significant investment in digital innovation, the construction sector continues to struggle with inconsistent, siloed data that impedes informed decision-making. Too often, architects and contractors are forced to operate with incomplete information, causing inefficiencies that begin from the earliest design stages and continue throughout the entire construction process. In fact, according to the State of Data Quality in Construction report, a typical project in the UK loses around £2 million to rework, delays, and procurement errors, all of which are rooted in poor quality or ill-managed data. This is far from a back-office issue: it directly impacts how buildings are conceived, costed, and delivered.
When it comes to protecting margins, waste plays a significant role. Globally, the sector is responsible for producing a staggering two billion tonnes of waste annually. And, in the UK, construction accounts for around 61% of all national waste, which equates to about 100 million tonnes each year. These numbers go beyond environmental impact; they represent substantial monetary losses stemming from over-ordering, needless material purchases, inefficient storage, costly disposal fees, and administrative burdens.
Material substitutions: an expanding risk
But the problem goes beyond just surplus materials. Supply chain issues, inflationary pressures, and regulatory changes mean that material substitutions are more frequent than ever. These amendments to specifications, though sometimes necessary, do not always deliver equivalent performance or compliance. As Cheri Haynes noted in a recent IRMI article, “you can put your boots in the oven, but that don’t make ‘em biscuits.” Here she underscores that substituting materials under pressure has no guarantee of like-for-like outcomes. And she’s quite right: even when done with the best intentions, poorly managed substitutions introduce unexpected risks – from invalid certifications to increased costs, safety issues, and potentially expensive project delays.
These risks are only heightened in today’s interconnected world as global events continually impact supply availability and pricing, increasing the need for material substitutions across the sector. However, regulations such as Gateway 2 place a greater focus on evidencing that as-built outcomes fully align with design intent. This means that any discrepancy discovered late in the process risks significant delays, project halts, mandatory rework, and compliance issues, all of which significantly erode already tight project margins.
Treating data as a core utility
With regulatory demands intensifying, compliance is now a continuous obligation throughout every stage of design, delivery, and occupation. Only robust, up-to-date data can provide the necessary certainty that the standards required are being met and delivered on site.
By adopting digital tools that capture and verify on-site realities against strategic requirements, project teams can ensure that final outcomes remain true to initial designs, therefore, reducing risk and avoiding costly last-minute adjustments. This means that treating data as integral project infrastructure enables teams to cut waste, enhance quality assurance, streamline compliance, and, crucially, eliminate needless costs such as over-ordering and excessive admin.
In one example, Morgan Sindall rolled out digital waste tracking for its Surrey Quays Overground station upgrade and saved £7,000 in administrative costs as well as achieving a 93% reduction in landfill waste. These gains came not through major expense, but by using better data to streamline operations and trim inefficiencies.
Seizing the digital opportunity
As the sector recovers, UK construction faces a pivotal moment. Embedding strong data disciplines throughout every phase of design and delivery is now vital commercially, while also playing a fundamental role in meeting sustainability targets. With proven tools already available and the business case clear, proactive firms can use data to reduce the risks – and the costs – caused by both waste and material substitutions, transforming administrative challenges into opportunities for operational excellence.
Ultimately, the future of construction will be defined not by grand promises, but by tangible results and decision making that is backed by reliable, actionable, data. Optimism is on the horizon, but it will only be felt by those who ensure that every decision, every material, and every process is underpinned by sound data that not only protects profits, but ensures that the places we build provide a comfortable and safe environment for those who will use them.
