Construction performed in dense urban environments like New York City can create serious effects on surrounding buildings and infrastructure. To minimize the risk of damage to adjacent structures, project teams must mitigate potential issues with protections and controls. These measures range from simple safety steps to very complex installations requiring specially engineered systems. In this presentation, we will explore typical and atypical risks associated with construction operations on adjacent buildings and review protections required under the New York City Building Code. 

After attending this seminar, participants will be able to: 

  • Identify common risks to adjacent structures during construction.
  • Discuss unique situations and concerns affecting adjacent structures during construction.
  • Identify minimum code requirements for protecting adjacent structures.
  • Recognize typical systems and controls used to protect adjacent structures.

Nathaniel Smith has extensive engineering experience involving structural design, building damage and collapse investigation, repair and rehabilitation projects, and foundation installation monitoring. His background in geotechnical engineering and understanding of soil and foundation types help him perform structural evaluations of existing buildings and investigations of structural damage and collapse. He also draws from his experience as a full-time field engineer in his design and investigation projects. Nate has worked on numerous projects related to the effects of construction on adjacent structures including pre-construction mitigation and risk assessment, damage assessment, and repair design, and has presented widely on the subject.
