The Road To GEMZ: Part One
It’s All About the Data, By Tim Warneford
The Road to GEMZ (Great Estate Management Zero) is a four-part blog series highlighting the challenges academies face in achieving strategic oversight of their estates, often leading to misinformed decisions and poorly costed outcomes. This is the first blog in the series, read the second instalment here.
Over the past two decades, successive governments have undertaken three national programmes to collect data on school conditions: the Property Data Survey Programme (PDSP) and two iterations of the Condition Data Collection (CDC 1 & 2). The goal? To better understand the state – and cost – of managing the 160,000 buildings that make up our 22,000-school estate.
In my view, the methodology has been fundamentally flawed – especially if success is measured by how effectively the data informs efficient, cost-effective investment decisions.
The data returned to the Department for Education (DfE) has consistently been too high-level. These surveys, based on visual-only assessments, skew the results by underestimating both condition severity and priority grading. This has been repeatedly disproven by more detailed, school-commissioned surveys, which often reveal far worse issues – and significantly higher investment needs.
The old adage “measure twice, cut once” was effectively reversed. The data lacked the depth and accuracy needed to drive meaningful action. This shortcoming has had serious consequences – most notably in the delayed response to RAAC. Despite widespread awareness of the risks, RAAC was not even factored into the national survey methodologies.
Without robust condition and cost data, the DfE was unable to make a compelling case to the Treasury. The result? Chronic underfunding for an ageing, deteriorating estate. Time after time, the DfE underestimated both the scale of the problem and the cost to fix it – while the gap between need and investment grew ever wider.
True asset management relies on proactive planning. It’s a long-term strategy that delivers value by anticipating problems before they escalate. Yet, the DfE has defaulted to a reactive maintenance model – sacrificing long-term efficiency for short-term fixes. That imbalance will only worsen as schools face the added pressure of decarbonisation targets.
You can’t plan effectively without first qualifying and quantifying your data. Accurate, up-to-date, and costed information is not a luxury – it’s a prerequisite. Without it, planning becomes guesswork. And where guesswork prevails, risk multiplies. When clients can’t define what they need, contractors price in the unknown – raising costs and compromising delivery.
Whether you’re an individual school, a multi-academy trust, or the DfE itself, the same truth applies: investing in detailed asset intelligence delivers clearer scopes, more predictable costs, and less risk. Cutting corners in the assessment phase may save money now – but the long-term price can be steep.
It’s a curious thing when government fails to follow its own guidance on best-practice estate management – while individual schools, supported by the right consultancy, often achieve far better outcomes.
Next up in our four-part series, ‘The Road to GEMZ’: I explore how to shift from reactive fire-fighting to strategic estate planning – and why the future depends on smarter data, not just more of it. Stay tuned.
