What People Say About Us

Over the past several years I have found DVR Consulting to be my “go to firm” whenever a code question has arisen.  Kevin and DVR have always been quick to respond to any question and their knowledge of the code is unsurpassed.   Whether it is a quick question on a small project or full report for a multi-million dollar development DVR has always come through and it is comforting to know that this valuable resource is a phone call away.

Kevin Riley, President, KPR Owner Representation

I entered into a subcontract agreement with DVR for third party fire alarm review services for the DC Marriott Marquis, and I was very pleased with their services.  DVR completed a very thorough review of the fire alarm shop drawings, calculations, and submittals and was extremely helpful in communicating directly with the vendor to resolve all issues.  Mr. Vander Roest was readily available as a source of information throughout the process and promptly responded to all inquiries related to the complicated system under review.

I would highly recommend the services of DVR Consulting, LLC for third party fire alarm reviews and plan to utilize their services in the future for my fire alarm review needs.

James Herndon, PMP, Truland Systems

Without the assistance and guidance provided by DVR, we could still be dealing with issues from the authority having jurisdiction!  DVR was able to resolve many issues and calm a difficult situation with the County and Owner through intimate knowledge of the applicable codes and standards and extremely logical approaches to fire protection and life safety strategies for a challenging day care occupancy.  DVR was on top of its game, and coupled with reasonable rates, proved to be a value added bonus to keep our costs in line.  I really enjoyed working with DVR, and they saved us from significant modifications due in large part to the AHJ, but also from some deficiencies they found in our design documents.  DVR is on our list for upcoming projects, and my partner and I both thank you big time!
