E2PM was involved in supporting a new commercial reconstruction project within the Gansevoort Market Historic District (a.k.a. Meat Packing District) at 402 West 13th Street in New York City, New York.
The new reconstruction activities were located within the Gansevoort Market Historic District (a.k.a. Meat Packing District), which was designated on September 9th, 2003 by the NY City Landmark Preservation. The district is bounded by the High Line to the west and Greenwich Village Historic district to the south. NY City Department of Buildings Technical Policy & Procedures Notice # 10/88 dated June 6, 1988, requires that for any structure designated a NY City Landmark or located within an historic district and is contiguous to or within a lateral distance of 90 feet from a lot under development or alteration shall institute a monitoring program where the structures of interest shall be monitored for vibrations.
E2PM was contracted to inspect the structures adjacent to the proposed reconstruction. Initially, when E2PM became involved with the project, the site property was an empty lot with the former structure recently demolished. E2PM was responsible for conducting a Pre-Construction Assessment Report; installing five (5) seismographs (Instantel Minimate Plus advanced vibration); conducting baseline vibration monitoring; installing survey target crack gauges; measuring bi-weekly to make sure no movement was occurring during construction/underpinning activities; creating and implementing monitoring protocols, video and photo documented all activities and completed a final inspection report at the end of all site activities.
