Peer Review is an intense, in-depth review of plans critiquing the design decisions made by the engineer and/or team. This can be used as a performance evaluation but can also be used as a plancheck before submittal or a proof of design concept early in the design cycle. The suggestions in a Peer Review will include changes to the design to make the project work better, cost less, or eliminate complications during construction but may not be practical to implement given the timeline to make the changes and the number of plans that may be affected by the changes.
