The Facts on the Ground
When liability comes down to precise measurement, not opinion.
When a case hinges on a sidewalk height differential, a disputed property line, or an easement no one can quite agree on, opinions won’t hold up — precise, defensible measurements will. Frank S. Ferrantello, PLS brings decades of licensed surveying expertise to insurance defense teams, carriers, and counsel who need fast, objective, litigation-ready evidence.
From §7-210 sidewalk claims in Manhattan to boundary disputes in Brooklyn and accident site mapping in Queens, Expertmapco turns complex site conditions into clear exhibits that adjusters, judges, and juries can understand — and that hold up under cross-examination.
