The American Society of Civil Engineers (ASCE) promotes and supports the use of peer reviews for projects. Peer review is the practice of obtaining an independent, unbiased evaluation of the adequacy and application of engineering principles, standards, and judgment from an independent group of professionals having substantial experience in the same field of expertise. Peer reviews are in addition to the normal quality control and checking procedures required on any engineering assignment. 


Projects are expected to meet industry standards of performance. Peer review is a separate, important step in the design process for selected projects to provide an evaluation of design concepts and management to meet performance objectives. Peer reviews are recommended on projects:

  • That are critical or could endanger public health, safety, welfare, the environment, or national defense or security.
  • Where performance under emergency conditions is paramount.
  • When using innovative or untested materials, techniques, or design methods.
  • That could result in significant financial or operational losses. 

Peer reviews should be initiated or requested by the owner/client or regulatory agency with full cooperation from the designer or consultant. Reviews address a defined scope as set forth by the initiating party. The number and timing of peer reviews vary by project. Reviews should normally occur before critical decisions or criteria are adopted as well as prior to the completion or release of contract documents. Peer reviews should be performed by independent or external professionals not associated with or accountable to the original design team.


Quality control and checking of engineering project deliverables is an important but separate process normally undertaken by the designer, associated team members and organizations. Peer review can add a measure of increased confidence to the designer or consultant which leads to improved practices and benefit the public health, safety, and welfare.
