Fort Warren, situated on Georges Island in Boston Harbor, boasts a rich history spanning over a century and a varied role in national defense. The construction, which commenced in 1833 and underwent multiple adaptations driven by evolving warfare technology, culminated around World War II. The Massachusetts Department of Conservation and Recreation (DCR) often faces tight design schedules from when a project is funded to when the project needs to go out to bid. This trend is expected to persist for the next two decades, with numerous independent projects slated for Fort Warren. Given the substantial size of the fort, hand-measuring the existing site would have been a nearly impossible task. Especially considering elements like non-perpendicular walls and arches, obtaining accurate measurements would have been highly challenging.
