Nitsch Engineering provided laser scanning and traditional land surveying services for Old City Hall, located at 45 School Street in Boston, to support exterior building renovations, courtyard improvements, and a planned archaeological dig on the historic site.

While the building, constructed between 1862 and 1865, is historically significant, the site of Old City Hall is also historically important. The Boston Latin School, Boston’s first public school and the oldest educational institution in the country, was built at this location in 1635. When Boston’s City Archaeologist found records showing that the portion of the property which housed the original schoolmaster’s house had not been built on since the 17th century, they realized that they had the opportunity to excavate a spot in the heart of the City.

To support this dig, the Architectural Heritage Foundation, which operates the building under a 99-year lease with the City, asked Nitsch Engineering to prepare a site survey that would serve as the base drawing to define the dig boundaries, support archaeological submissions to the City and the Massachusetts Historic Commission, and support future courtyard and exterior building renovations.

Using a combination of traditional land surveying and laser scanning techniques, we located a number of site features, including fences, statues, terraces and significant plantings, and scanned the building façade. We prepared existing conditions site plans, researched and compiled utility records, and provided boundary line determination for the site.
