Although these professionals have extensive knowledge in preventing water from entering your home, very rarely do they have an engineering background. Structural engineers are trained to understand the forces and stresses acting in your home. Structural engineers can evaluate cracks and other possible structural problems to determine if repairs are necessary.

Robert and his team are consummate professionals and I have trusted his advice - and engineering plans - over the years on many DC and MD homes for guidance -- including complete restructuring of several older homes or ones that have been poorly remodeled by others.

I have worked with Robert on a myriad of large and small renovation and new home projects over the last 10 years, probably over 50 projects. Not only is he super professional and accommodating, he is also very reasonably priced for his level of service. I highly recommend him and use him exclusively for structural engineering for all of my projects.

We have worked with Robert Wixson and APAC Engineering for almost 20 years now. Extremely professional and knowledgeable in the world of high end home remodeling. APAC understands how DC area homes are constructed and has solved numerous complicated structural issues that we have brought to his firm for our projects. We recommend him very highly.

I have consulted with APAC on Architectural projects for the last 7 years and have never been happier with the level of knowledge and professionalism he has displayed. Robert, has seen and worked on buildings of all types. There is very little he has not seen. In fact, when working on older houses in the DC area, I am amazed at his ability to deconstruct a building before a contractor has started stripping the plaster.

His documents typically have very few comments from reviewing agencies and I have yet to have a contractor complain about his drawings. Most importantly he has been easy to work with offering information and solutions for issues that may arise on projects he has worked on with us, and sometimes projects that he has not worked on. I will always appreciate that level of collaboration. I would always recommend him for residential projects!

I have worked with APAC Engineering for years, on many projects, from very small and straightforward renovation and addition projects to much more complicated whole house solutions. Robert provides concrete explanations and solutions that are not just generic. He is easy to work with and treats all with respect, courtesy and will give you an honest answer.

I feel confident that my design vision will come through with Robert as the structural engineer and genuinely enjoy collaborating with him. He and his team offer top notch engineering service that has been recognized throughout the DMV as such. I have recommended him to clients and friends and would not hesitate to do so again.

My firm has worked with Robert for 20 years plus. We have never had an issue with any of his engineering solutions. In fact, we have been complimented by building inspectors on the structural designs provided by APAC. Robert is also a upstanding person and a breeze to work with. Always has a positive attitude and delivers his work on time and in a pleasant manner. I have referred Robert to other contractors and their experiences have been exactly the same.

My name is Jerry Levine, president and owner of The Levine Group Architects + Builders Inc, a locally and nationally recognized design/build remodeling company servicing the Metro DC area for nearly thirty years. We have used Robert Wixson of APAC on countless residential projects that require the skills and insight of a structural engineer. His clearly unique ability to see solutions that combine physics, building science, jurisdictional code requirements and the practical need of the remodeler and the client are rare and.in my opinion.treasured.

His approach to solving problems is a perfect addition to the philosophy and culture of my company. I would choose Robert to solve our remodeling structural problems every time.

Had Robert, a structural engineer, check out some issues with a house we were interested in buying. Accommodated our short timeline, provided a writeup of his opinion quickly, gave us cost estimates, helped us prioritize repairs, and talked through all of our options in a way we could understand. Highly recommended!
