Steps

  1. Fetch NYC DOB's current 'Erecting Tower Cranes: Required Protocol for Third-Party Certifications' PDF and the CN Application step-by-step guide from nyc.gov
  2. Confirm the Engineer of Record (EOR) must submit third-party certification letters, reports, and documentation before DOB's Cranes and Derricks Unit reviews the CN application
  3. Note certification letters must reference CN approval number, Crane Device (CD) number, crane serial number, model number, and project location
  4. Confirm the inspection scope required: complete inspection and non-destructive testing of structural, mechanical, electrical, and control components
  5. Confirm applications are queued and reviewed in the order received only once all required items are submitted — build filing lead time into the inspection company's schedule
  6. Contact DOB's Cranes & Derricks Unit directly to confirm current filing procedure, since DOB NOW: Build system steps can change
