"Dee is fantastic! We loved the design Mike came up with for our backyard makeover. Then once construction started we realized we had made choices that needed to be changed. In every case Dee's suggestions (stucco the walls instead of paint, don't use DG next to the pool, run wood fence topper horizontally) turned out to the best. We are so glad we listened to him. Our finished backyard looks like an art installation but one where you can feel comfortable and at home. Now a year later we had them come back for a few tweaks and again Dee's suggestions were the right ones. We are happy we choose G & L and plan to use them again next year when we tackle our front yard."

"Stuff happens, and this business knows how to handle it! We had a stain on the ceiling. Ofri from BTB came over and turned on the water from the upstairs bathtub and then the shower stall. The ceiling became moist after the shower was turned on. Ofri then came back with a plumber. He turned on the upstairs bathtub. After they left, water dripped from the ceiling. Ofri had the plumber immediately send over a team for a service call. They broke open a hole in the ceiling and found that a pipe leading to the bathtub was so rusty it had holes. They took videos showing other pipes leading to the bathtub were also very rusty. While the team was still there, Ofri gave us prices, sent over the paperwork and the pipes were replaced within a of couple hours. Fabulous! Ofri had thought it would take a lot longer to complete the plumbing work. Therefore, her pricing did not align with the actual work performed. She brought in Alon, who substantially reduced the price to our satisfaction. Their responsiveness and reasonableness earned them my highest rating. Thank you Ofri, Alon and the BTB team!"

"I worked with Alpha once before, and they assisted with a second project 2 years ago which, now finally completed, I'm able to write a review about. Alpha helped with structural plans for windows in a garden level unit in order to prepare the proposal for city approval. Alpha is a big company and it took them a little while to complete everything; however I can certainly say that the engineer and contact people were knowledgeable and thorough. The plans were approved with their help and now that the unit is permitted for occupancy, the windows are a lovely attribute to the space."

FAQs for engineer structural projects in Newbury Park, CA
In most cases, yes. You’ll get a complimentary assessment based on your home’s size and the project scope. Simple inspections come with a flat fee tied to your foundation type and square footage, while larger jobs call for an on-site evaluation before the formal estimate. Either way, an up-front quote gives you a clear budget before work begins.
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.
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.
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 often 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.
