Best Structural engineers in United States

I used RESolutions in 2021 to design an enlarged beam and change it to a flush beam rather than a drop beam when we enlarged a patio door and just now to determine load bearing walls and a foundation crack. Matt was an absolute treat to work with each time. He is both personable and thorough in sharing the structural engineering of your situation. I even learned why there are so many nail pops in my house with a hip and ridge truss system

ANCO Environmental did an outstanding job removing an oil tank from my basement. Ernesto and the crew worked efficiently and cleaned up spotlessly. Angela and the office staff went above and beyond to make it a painless experience. Highly recommend.

I'm so pleased that I chose ANCO to extract the oil tank & clean up. Angela has been extremely helpful keeping me inform of the progress. The men onsite were extremely professional. I would always recommend this company to anyone who needs this sort of job to be done correctly.

The people at ANCO did a great job of draining and removing our oil tank, and removing the oil which had leak out of the tank.

Ernesto is Best Gentelman in this company !
Professional, always on time ! Means ( if you are not 15 min before - means you Are LATE)
Never missed an oil tank !

I'm so happy that I chose ANCO with extracting the oiltank and clean up. The owner Mark has been so helpful with keeping me in the loop of the progress. Everybody in his team has been great,,from the staff in the office to the crew in the field.
Thank you Mark for going out of your way to help me.
I can easily recommend this company to anyone who needs this sort of job to be done efficiently and professionally.
Thanks again

I worked with Anco when I had an oil tank removal and soil remediation. Mark explained the EPA regulations and kept me informed through the process. His company worked with me to apply for a grant and is still helping to complete the application. Staff is grateful also & very professional.

Fantastic experience working with Charlie. Our recently built, 7-unit condo building was experiencing flooding in the bottom units. Charlie oversaw the entire process from investigation, excavation, to eventual repairs. This was nearly a year-long process and our condo was lucky to be working with Charlie. He was honest, thorough, prepared professional-level documents (including for legal use), and overall was just great to work with. Would recommend to anyone looking for a structural engineer.

Exceptional team and leadership with exceptional knowledge! Project lead by Charlie and his support team of Avi. Their pricing fit the budget perfectly for the work that was needed and communication was amazing. I can’t wait for the next opportunity to work with this team again. They truly get it!!!! This is the team you definitely want on your jobs.

As an architect, I am working on a project with CG Consulting engineering. I have found his work to be very professional, detailed, service oriented, and the principal Chris has the long-term interests of the client in mind. I would gladly work with him again.

Awesome Company! Workers were very professional and did an excellent job removing a 550 gallon oil tank that was buried in our driveway. Removal of the tank was amazingly fast and went well. After the tank was inspected by the city, Anco removed the tank safely away from the property. I highly recommend Anco Environmental.

Wonderful Company who skillfully removed a 550 gallon oil tank that was buried in our driveway for over 60 years! Great experience with very pleasant Workers who painstakingly did an hours-long job on a very hot, humid Summer day. Anco Environmental stayed on the job site until the tank was inspected by the city. Then they removed it. Awesome experience!!

I had the pleasure of working with John and his team on a complicated healthcare project. We needed assistance from his team and their expertise on seismic monitoring. They provided assistance using their knowledge and positive team approach. They provided a seismic monitoring solution through Sensequake that delivered real peace of mind.

- Robert Hartelust - PX Skanska

We have worked with Robert for about 10 years. After meeting and working with Robert we have no desire to ever work with a different engineer. He works with Smiley Renovations to come up with practical and reasonable repairs / engineering designs for new projects. He has always been an absolute professional and we look forward to many more years working together. We would not hesitate to recommend APAC to anyone.

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.

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 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.

I have known Robert for almost 20 years, and since the first project that we worked together, I knew that I was not going to need or use any other structural engineer for my projects. I would not be able to do any of my residential projects without his help. Thanks to his extensive construction knowledge, attention to detail, honesty, excellent customer services, and quick thinking to resolve any structural issues that may come up during construction, we have designed and built 100’s of projects together.

I would recommend APAC Engineering for any of your structural needs if you want your projects to be successful, keep your clients happy, and have your project comply with any permit jurisdiction.

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 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.

I've worked with APAC Engineering both professionally and personally for close to 15 years. Robert has completed structural design work for me, my family, and my professional clients. We have literally worked on hundreds of projects together. He is my "go-to" structural engineer. He is always professional and has a firm understanding of both the permitting requirements and practical designs for me and my clients. I don't leave many google reviews, but seeing the completely off base negative review inspired me to comment. Robert is one of the most honest, ethical and professional consultants I work with and a track record of 15 years of quality service and hundreds of successful projects stand behind that assessment.

Pretty responsive for scheduling. Awesome job with the consultation. Inspector was very informative and made sure to clearly explain everything to me.

I hired Structural Solutions to design a roof deck, giving them $475 as a retainer. They'd given me an estimated schedule of 2-3 for completion. Two weeks after receiving my retainer and not returning my calls I was informed that the engineer working on the project left the firm. Personnel changes happen, but then I was then informed that it uncertain when anyone else in the firm would be able to perform my job. Okay, so I'd like my retainer returned. He refused to refund my retainer because the engineer who left had already started to work on it -- no usable product to me though! I shouldn't have to absorb the cost of their personnel problems. Only after some pestering did they return my original drawings.
