What gets missed, and why
The project risks that cause the most damage tend to share a common characteristic: they are knowable early, but they require someone to look thoroughly.
Access and transport are the most persistent offenders on out-of-hospital and primary care estate projects. Sites get shortlisted because they’re available, because they’re in the right place geographically, or because a GP practice or community trust already holds a long lease on adjacent land. Whether an access arrangement can actually be delivered, accounting for blue-light vehicle tracking, patient drop-off and pick-up volumes, and staff parking, is rarely stress-tested until the planning application is sent out. By then, the scheme is committed, the business case is drafted around it, and funding amendments are not a realistic option.
Flood risk and drainage in clinical settings pose a specific risk that is often overlooked. Sequential and exception test arguments can usually be made to work. What’s harder to overcome is the cost of a drainage scheme on a constrained site – and harder still is the operational reality that arises for the end users. Diagnostic equipment, in particular, carries genuine flood vulnerability that can’t be fully designed out. An MRI suite or a sterile services area at ground-floor level on a site with a residual flood risk is not just a planning problem but a clinical risk that someone eventually has to own.
Utilities deserve more serious attention than they typically receive in healthcare scheme appraisals. The assumption is that a hospital or health centre is a straightforward connection with the NHS, being an established institution, gaining permanent use. The reality is that modern diagnostic and treatment facilities have significant electrical demand, and reinforcement costs in areas with constrained grid capacity can be material. A pre-application utilities capacity assessment is cheap relative to the cost of a reinforcement quote that arrives after the OBC has been submitted.
Ground conditions and environmental constraints follow the same logic. Phase 1 desk studies are standard. What’s less common is conducting a detailed investigation before a site is formally approved for the business case proposal. The cost of remediating unexpected discoveries in the ground, even if they are beneath a car park earmarked for development, is not a minor line item. The same goes for ecology constraints.
