Welcome to A & A Structures LLC, proudly servicing Bethesda and the surrounding areas. We provide Structural Engineering services for residential buildings, which include: modification to the building structures, structural damage assessment and solution, structural plans for building permits, and similar projects.

"I had a great experience working with A & A Structures LLC for the structural engineering work on my home renovation in Bethesda. They were easy to work with, extremely fast, and delivered permit-ready documents that were clearly tailored for Montgomery County DPS—right down to the correct file naming conventions, which matters more than people realize. When the county requested minor revisions, A&A responded immediately, made the updates without hesitation, and even worked directly with my developer to clarify requirements. All of this was handled under the original fee, which I felt was an excellent value. Professional, responsive, and clearly experienced with Montgomery County’s approval process—I would absolutely recommend them and would use them again without hesitation."

"Initial rep was great and informative. Felt comfortable with initial sale. Hardly had any contact from customer service except for the payments. There were several delays that we were not informed about unless we called to ask. Took 7 months before they showed up to begin project. Only 1 person was sent to build steps. Took a week. Hard worked, hardly took a break. Had to call again to see when they would come to pour patio. Never knew when they were coming, they just showed up. Hardly spoke with the homeowners. Inspection paperwork was just left on porch. Additional paperwork that is "required by the County" had to be completed by homeowner and taken to Court house to be notarized and filed and also provide a copy back to Long Fence. Time sensitive materials which added to homeowners to-do list. Gave this contract to LF on the surface of their history and appearance of a 'good local company' but should have stayed with original contactors in VA. Puddle of water forms when it rains"

Daniel started his construction career in 1983 as an apprentice in Switzerland, Europe. There he learned from experienced old school carpenters how to timber frame and build log houses. Cutting mortise and tenons for structural posts is still something that's done today. Since the late 80's, Daniel has learned all about the ever-changing U.S. construction industry. Daniel started his own remodeling company in 2001 and has since designed and built many additions and remodels in and around Montgomery County, MD. Due to years of experience, Daniel is able to make design changes that make construction easier and cheaper. He has proved himself to be a great communicator so that all parties involved in a remodeling project work as one. His ability to plan, schedule, and execute projects have made jobs less stressful and more rewarding for his clients. Things most frequently mentioned in client reviews are that Daniel and DK are staying within budget, getting the job done on time, are responsive and available, have clean and organized job sites, and are experienced.

Family owned and operated for nearly a century, we understand the value of our own reputation like very few others. Over the years, we've continued a tradition which goes deeper than quality work, advanced technology and superior service. Hawkins today is every bit as focused on customer service, and getting the job done right, as it was back in 1918. As technology advances, so do we. In fact, Hawkins' trains its staff regularly, and has always been quick to adapt to new ways of doing things. We remain as innovative and prepared as the days when the traffic lights we were installing were among Maryland's first. But there's just no replacement for some old-fashioned values. We simply say we're Wired for Service. It's who we are. Additional phone numbers - Baltimore & local areas, (877) 927-0900, Virginia area - (301) 419-3214. Additional contact name - Todd Shatzer. Additional service areas - portions of DC, Charles & Calvert Counties. Award winning.

FAQs for engineer structural projects in Gaithersburg, MD

To determine if a wall is load-bearing, start by checking your home’s original plans or asking a structural engineer. Exterior walls always carry weight, but interior ones only do if they sit over a beam or run perpendicular to floor joists. If a wall lines up with posts in the basement or falls directly under the roof ridge, assume it’s load-bearing and call a professional before attempting to remove it with a sledgehammer.

Calculating the wall load and sizing the beam must be performed by experts to ensure structural safety. You need a structural engineer to evaluate all load aspects and determine the proper beam dimensions. A professional engineer performs precise calculations and advises on any necessary enhancements, such as larger footings for support. An inspector then verifies that the revised structure meets all safety and code regulations before the finishing work begins.

Hiring a structural engineer is essential for ensuring your home remains structurally sound during any major renovation. Their responsibility is to deliver expert assessments and design recommendations for load-bearing modifications. The average cost to hire a structural engineer is $500, with rates ranging from $350 to $800. Consulting a licensed, experienced engineer guarantees that every structural project, whether constructing a new home or remodeling an existing one, is completed safely and efficiently.

Almost all load-bearing wall removals require a permit as they support everything above it, and building departments want proof that the new beam can handle the weight. Pulling a permit triggers plan review and inspections that confirm the work meets local code and safety standards. Skipping this step can lead to fines or being forced to rebuild later, so have your contractor pull the permit before work starts.

Removing a load-bearing wall to create an entrance for a carport or covered patio is a task that comes with defined cost implications. This modification requires extra structural adjustments to ensure safety and proper integration with the adjoining space. When you convert a wall into an entryway, you can expect to pay between $3,200 and $9,500, with an average cost of $6,400. The additional work required for this conversion reinforces the home’s integrity and ensures compliance with applicable building codes.
