Our firm has logged over 955 projects spanning a wide variety of owners and facility types. This experience gives our firm an excellent, if not unique cross-pollination of designs.

With pleasure, we conclude that our roots are in Virginia, yet our projects are worldwide. From design-build to full service, we can provide the level of detail specifically required for each project.
We know that successful relationships lead to successful projects. We build long-term relationships by earning your trust through keeping our promises and maintaining the highest level of ethics and professionalism. Our extensive experience covers both Government and private sector owners, including courts, city hall, libraries, recreation centers, universities, primary and secondary schools, churches, restaurants, hospitals, shopping centers, single/multi-family residences, and others.

AJ Engineers was the MEP consultant on 6 projects for Fairfax FMD. I also worked in the private sector previous to joining FMD, and they had been involved in about 10 other projects that I was associated with. There were all types of known issues in the building, and they responded professionally to all the
problems.
