"They were excellent. They quickly made a draft that only needed 3 minor adjustments. The final product was exactly what I needed. They referred me to a structural engineer for review. The whole process took half of the time that they initially estimated. I would definitely use them again."

"I had the pleasure of working with Mark from Bartel Engineering on my attic conversion project, and I couldn't be more impressed with the project plans he provided. Mark demonstrated a high level of expertise and professionalism throughout the entire process. From the initial consultation to the final delivery of the project plans, Mark's attention to detail was evident. He took the time to thoroughly understand my vision for the attic conversion and translated it into comprehensive and well-thought-out plans. His expertise in structural engineering ensured that the plans not only met my aesthetic preferences but also adhered to the highest safety and structural standards. Mark's communication skills were commendable. He kept me informed at every stage of the planning process, explaining technical details in a way that was easy to understand. He was receptive to my feedback and made adjustments promptly, ensuring that the final plans perfectly aligned with my expectations."

"I needed someone to provide pushback against the local permitting department. I was told I needed a structural engineer to inspect the deck and that is what happened. I got constructive input on deck problems from the consultant and the permitting department backed off and started working with me. I view this as a success. The consultant communicates well and seems very knowledgeable."

"He listen to all of my concerns, fears, wishes. He was professional. And he was patient no sales pressure to make the deal. I feel confident in the success of this project."

"Andrew accomplished what he was contracted to do, which was draft plans for an addition to get it approved through Fairfax County. The biggest problem with Andrew is that he didn't listen, didn't write anything down and had to re-draft the plans. His powers of observation are suspect as the roof lines of the house were drawn incorrectly. He was distracted at the time so it may be that his prowess as a draftsman were masked by other distractions."
