Our firm provides structural engineering support for all phases in the design and construction process. Our primary function is to create structural plan packages for submission to the governing authority. We are also available to conduct preliminary field visits and structural observations during construction. In whichever service you need, we pride ourselves in carrying out the job professionally, quickly, and for an affordable price.

"I searched many and started off with others and nobody came close in handling what we needed. I found Richard, he came in and took care of it all; it was completed in a timely manner with his accurate thinking. He definitely thought ahead and it saved me a lot of time, grief and money. He got ahead of any issues and resolved potential problems that could arise. He knew exactly what the city would require and did what needed to be done which saved us an untold amount of time and money. I did not know him from Adam, he works at a very different level of ability and knowledge. His pricing for me was the best! He is a gem, get him if you can!"

Engineer structurals FAQs

You should bring in a structural engineer any time you’re adding or removing something that carries weight—think new construction, a major remodel, or moving a load‑bearing wall. Call one during a real‑estate deal, after storm damage, or when you spot cracks in the foundation, beams, or chimney. An engineer’s report confirms that the structure is sound and tells your contractor exactly what fixes—or reinforcements—are needed to keep the home safe long‑term.

Who you hire depends on the task. Hire an architect to shape the look and layout of your home. Call a structural engineer to verify that load‑bearing elements—walls, beams, foundation—can handle the plan or to diagnose structural issues. Bring in a home inspector for a broad health check during a sale, after a storm, or for an appraisal. Matching the pro to the job keeps costs down and problems in check.

During the visit, the engineer checks your foundation, framing, walls, roof, and insulation, then compares what they see to any existing plans. If the structure matches the specs, you get the all‑clear; if not, the engineer outlines the fixes. Their sign‑off is what lets the next phase of work move forward, so expect clear notes on what’s solid and what needs attention.

Civil engineering is the broad field that covers roads, bridges, and other infrastructure. Structural engineers focus on the loads and forces inside a building or bridge—foundations, beams, and walls—while mechanical engineers design and keep power systems running, from elevators and turbines to HVAC equipment. In short, civil handles the big picture, structural makes sure it stands up, and mechanical keeps everything moving.

Most structural engineers offer free quotes. They’ll look at your home’s size and the scope of work to decide whether a flat fee or hourly rate makes sense. Simple inspections are usually priced by square footage; bigger, more complex jobs require a site visit and a detailed written estimate. Getting that number up front lets you nail down a budget before any drawings or inspections begin.

The engineer reviews every load‑bearing part of the home—floors, foundation, walls, roof, and major beams—along with insulation and the soil around the structure. They also factor in local weather risks and nearby water sources. The goal is to confirm that the materials and construction can handle day‑to‑day loads and extreme events alike, and to flag any spots that need reinforcement.
