Qualified Retaining Wall Inspector (QRWI) Certification


There is a formal certification process for Qualified Retaining Wall Inspectors (QRWI) as per the NYC Rules and NYC Administrative Code.

In order to be certified as a QRWI inspector, the candidate must be a registered professional engineer in New York State.  In addition, the QRWI candidate will be required to document to the Department a minimum of three years of structural engineering experience in:

  • retaining wall design

  • support of excavation

  • structural design, and/or

  • forensic structural engineering assessments.

The QRWI candidate will be required to submit a detailed curriculum vitae (CV) with three sample engineering projects, regarding either the design of retaining walls and/or inspection and retaining walls structural repairs or forensic investigations.

*Note: In lieu of retaining wall-specific design and/or investigations projects, the QRWI candidate could also submit Support of Excavation (SOE) related projects.*

Upon the review of the QRWI candidate’s CV and sample engineering reports and projects, the Retaining Wall Unit will schedule an interview with the candidate. The interview will consist of a series of questions designed to examine the candidate’s knowledge of structural engineering and of the NYC Building Code and Rule requirements regarding retaining walls.
