Every story below is a real engagement, anonymized at the customer's request. The leaks were real. The exposure caught is real. Construction is hard enough — let the data do some of the lifting.
Independent research across US commercial construction puts average cost overruns at roughly 16% of project value. Rework alone runs 5 to 12%. On a $14M project, that's $2M to $2.6M of margin walking off the site — most of it never added up in one place, most of it never argued for.
That's the baseline. Tantalon's job is to surface a meaningful slice of it before it becomes irreversible. Typical engagements catch $150K–$400K per project. The Meridian story below is one engagement on a problem project where the dashboard caught a lot — that's the upper end. The point is the math is real either way.
Mid-size GC in the Midwest. Eleven open RFIs and eight submittals on a $14M project — with a clearly underperforming electrical sub already pulling the schedule apart. Three days into the engagement, Tantalon traced $199K of combined exposure to that one sub, and another $478K spread across schedule and cost across the project.
Above the typical $150–400K engagement range. We lead with this story because the math is the cleanest. Most projects don't run this hot — but most projects still leak more than the dashboard costs to catch them.
