The speaker highlights that manual reviews of site diaries capture only about 60% of legitimate change events, causing significant revenue loss—approximately £200,000 on a typical £5 million project with a 10% variation rate. This loss turns a 5% margin project into a 9% margin project, representing an 80% profitability boost if captured. To address this, the QS AI Agent, embedded within the Gather platform, continuously scans all project data (site notes, resource reports, weather logs, progress updates) in real time, interpreting them with the expertise of a senior quantity surveyor. It tags and documents commercial events as they occur, delivering actionable insights within the contractual window. The agent is trained on the user’s contracts and methods, integrates seamlessly without disrupting existing workflows, and augments—not replaces—the commercial team, providing them with “super‑human” reach to capture missed revenue opportunities.

Manual diary reviews only capture 60% of legitimate change events, the rest buried under sheer workload and time pressures. On a typical £5 million project with the standard 10% variations, that's £200,000 in missed revenue. Revenue that turns a 5% margin project into a 9% margin project. That's an 80% improvement in profitability. And yet those opportunities slip by because no human team can review every site diary, every detail, all in real time. With our QS AI agent, the opportunities, they find you. It lives inside Gather, scanning every data point the moment that it is captured. Site notes, resource reports, weather logs, progress updates— it interprets them with the precision of a senior quantity surveyor that never sleeps. It doesn't wait to dig through the site diary weeks after. It interprets the commercial event as it happens. It tags it, documents it, and puts it in your hands while you've still got the contractual window to act upon it. It's trained to use your contracts, your methods, your data, and it's wired directly into the platform that you already use. It won't disrupt your workflow, and it doesn't replace your commercial team. Instead, it gives them superhuman reach. Every day of manual review is potential revenue slipping away. The moment to recover value is now. With our QS AI Agent, you will see it in black and white while you still have the time to do something about it.
