The Cathedral of Saints Peter and Paul

Using The Montgomery House, a 220-year-old building in Lancaster, Pennsylvania, Existing Conditions illustrates how 3D laser scanning, point clouds, and 3D BIM models can be used in historical preservation. Existing Conditions documented approximately 5,000 square feet of the exterior, as well as the interior of the State Room at The William Montgomery House. We utilized the cutting-edge Leica RTC360 3D laser scanner to 3D laser scan in color.

To aid the historical preservation plans for The House of the Seven Gables, Existing Conditions 3D laser scanned and modeled exterior shells of The Turner-Ingersoll Mansion (also known as The House of the Seven Gables), The Retire Beckett House, Hooper-Hathaway House, Nathanial Hawthorne Birthplace, Primm House, and features of the Seaside Colonial Revival Gardens. We also 3D laser scanned the Nathanial Hawthorne Birthplace basement to create a 2D floorplan to assess the challenges related to flood-proofing. Existing Conditions' as-built data will help to identify structural issues, deterioration, and other factors affecting the historical site, and deliver our client, Union Studio, 2D plans and a 3D model to develop architectural designs for restoration.

Existing Conditions was selected to provide 3D laser scanning and construction drone services for the iconic Pinnacle Penthouse at the Woolworth Building, as the purchaser intends to restore portions of the exterior to more closely reflect the original 1913 Cas Gilbert design and finish the interior living space. With the help of Existing Conditions, this blank canvas of architectural history will be transformed into a masterpiece.
