Kurfees Self-Storage

In 2016, the historic Kurfees Paint Building located at the northeast corner of Brook and Market Street was redeveloped into a self-storage facility. Constructed in the early 1900’s, this well preserved building is on the National Register of Historic Places. The original, west-most section of the building was built in the year 1915 and served as the production plant for J. F. Kurfees Kurfees Paint Company. In 1928, a large addition was constructed along the east side of the building, providing almost double the original square-footage. Overall, the facility stands four-stories tall with a total enclosed space equaling approximately 110,000 square-feet. Structurally, the building is primary framed of reinforced concrete. Each level of the building specifically contains a grid of columns with the exterior walls composed primarily of multi-wythe brick and window glazing. The floors are 2-way, flat slab construction with perimeter spandrel beams and drop panels at interior column locations. The building also contains a basement, which in some areas, extends beneath the sidewalk located at the exterior of the building.

Leonard Engineering was privileged with providing structural engineering services for the renovation of this historic building. Leonard Engineering was initially tasked with conducting a series of structural analyses on the suspended floor systems to determine the live load rating. The process was necessary to ensure that the building had adequate strength to support the storage load conditions. Leonard Engineering also provided a full set of structural plans which included permanent shoring designs for the vehicular unloading area, floor infill designs at demolished stairs, elevator foundation designs, and concrete repairs to the building framing. In addition to design services, Leonard Engineering also provided Construction Administration services, as well as Special Inspection services, during the construction phase of this project.

Furthermore, in addition to the building renovation, Leonard Engineering also provided structural engineering services for the sidewalk rehabilitation project that is to commence along both Brook and Market Street. Leonard Engineering was tasked with providing retaining wall designs so that the portions of basement located beneath the exterior sidewalk could be backfilled and capped with a new sidewalk slab. It is anticipated that this design approached will increase public safety as well as prevent a reoccurring issue with sidewalk deterioration and water leakage into the basement space.
