"Mr. Ohi came to our home to inspect the foundation and support walls prior to us doing home renovation work. He did a thorough visual inspection and level measurements and located some small issues, but, thankfully, recommended that no foundation work be done. Mr. Ohi was pleasant to be with and knowledgeable about residential support structures."

"We hired Bitarchitects for a major renovation of our home and were extremely pleased with the experience. It was a substantial investment, and we valued the architects' expertise and guidance throughout the project. From the beginning, we had the opportunity to speak with several professionals, hear different perspectives, and make informed decisions. We worked closely with the architectural and design teams, followed by the structural and mechanical engineers, before moving into permitting. Although permitting presented some challenges, the team remained engaged and continued working with us until we successfully completed the process. Bitarchitects then helped us navigate construction and coordinate the different contractors, subcontractors, and agreements involved. Having one integrated team guide us step by step made a complex project much more manageable. We appreciated their knowledge, persistence, and continued support, and we highly recommend Bitarchitects."

"We tasked Gary with a very quick turn around on a project involving a total renovation of an existing structure as well as an addition. We had a very tight time constraint and Gary was able to accommodate us, utilizing his expertise to help us make thoughtful changes to our original design and educating us on Maryland code where needed! His final product is beautiful and it was exciting to see the “after” Reno elevations! I would use him again without a second thought and recommend him to my friends. Kelly Z."

"Todd has been a pleasure to work with. We asked him for help in designing plans for a renovation for our 1960s home. The existing home had a one-car garage, and we wanted to expand that to a two-car garage and add an extra room for a second work-from home office, as both my husband and myself work remotely. After reviewing our lotâ s survey, it was discovered that we were too close to the property line to expand the current garage, which necessitated putting the new garage on the other side of the house. This added another layer of complexity to the project, as we now needed to incorporate the existing single-car garage space into our home as usable living area. Todd listened to our ideas for repurposing the space, and provided good recommendations of his own. As others have mentioned, he worked well with our builder and quickly answered questions from the county permit office, expediting the permit approval process. We would have no hesitation in using Todd for our next project."

Structural Engineering FAQs, answered by experts

In Gaithersburg, schedule a structural engineering assessment if you notice stair-step foundation cracks, uneven floors, or doors and windows that suddenly stick. These issues often result from shifting clay soils and seasonal moisture changes. It’s also wise to book an inspection before major remodels or after heavy rainfall. Early summer is ideal, helping you avoid delays from permit backlogs and unpredictable weather.

Helpful?

Combining structural engineering with upgrades like basement waterproofing or energy-efficient window installation in Gaithersburg can streamline your project and reduce disruptions. Coordinating these improvements allows for shared inspections and more efficient contractor scheduling. This approach is especially effective in spring or fall, when weather is milder and permit processing tends to move faster, helping you avoid unnecessary project downtime.

Helpful?

In Gaithersburg, unexpected costs may arise from additional permit requirements, last-minute plan changes, or extra inspections due to local regulations. Issues like discovering hidden water damage, unmarked utility lines, or the need for mold or asbestos remediation can increase expenses. Weather-related delays and limited equipment access on older properties are also common, so it’s smart to budget for unforeseen repairs and restoration needs.

Helpful?

To keep your Gaithersburg home safe during structural work, schedule major repairs when children are at school or away. Secure basement and crawl space access, since these are frequent work zones. Use dust barriers and air purifiers to minimize allergens, and store tools and materials out of reach. Setting up temporary fencing or gates helps protect both kids and pets from entering hazardous areas.

Helpful?

When hiring a structural engineer in Gaithersburg, prioritize professionals with experience handling local soil movement and knowledge of area-specific building codes. Ask about their familiarity with regional home designs and check for recent project references nearby. Confirm they carry proper insurance and understand the city’s permitting process, as this ensures smoother coordination and helps prevent project delays or compliance issues.
