PLAN DROP OFF FOR FAIRFAX: Due to security protocols at the Herrity building, access to the ESI Fairfax office is limited to staff only. All plans submitted for ESI MSR review must be logged in at the Records and Information Management (RIM) counter on the 5th Floor. Engineers reporting for Peer Review or to meet with ESI staff must call 703-324-1942 or 5167 to announce their arrival on the 5th floor in order to be escorted to the ESI office.




The ESI Peer Review Program in Fairfax County consists of a Minimum Submission Review (MSR). This program provides a plan quality control review to save the time of the regulatory reviewers and speed the process of the plan approval.   The Minimum Submission Review involves peer review performed by ESI’s Peer Review Team (PRT), which consists of rotating private industry/governmental peer review engineers and an ESI Staff Engineer. The PRT is committed to review the plan within 48 hours from the receipt of the plan by ESI.  The peer review is done according to the appropriate established current checklist as listed in the following lines.  The Peer Review Team makes a final determination whether the result of the plan reviewed is AcceptableAcceptable with Inserts, or Non-Acceptable according to the checklist and/or response letter prepared by the submitting engineers.  If the plan review result is unacceptable, the submitting DPE engineer will get a non-acceptable grade and is subject to a disciplinary action from the Fairfax County Advisory Plans Examiner Board (APEB) as a built-in accountability measure. The submitting engineers will be notified of the status of the plan review results by phone or email by the PRT once the review is completed.
