"ESG Design was great to work with. I contacted them through Home Advisor for an impartial assessment of the cause of cracks in my ceiling, plus a few other issues. Eli, the engineer, did a thorough inspection and developed a solid plan for repairs. ESG also offered two levels of fees, which was extremely helpful for my budget. Thank you ESG for the service and peace of mind!"

"Ryan and team did a fantastic job of helping us with a project to repair a beam that was structurally unsound. We were kept very well informed of all key events and as usual (we’ve worked with Ryan several times) everything went without a hitch. Ryan and team do an outstanding job, and we would not hesitate to work with them again."

"I used Triple V as the Project Engineer for a garage conversion to single family residence for my son’s family. Vic not only did the engineering for us, he also did the structural drawings we submitted to the county as part of our permit package. He delivered the plans promptly, and worked collaboratively with us to resolve issues we identified and revise the drawings accordingly. The county building department approved the plans and issued the permit. During the project construction Vic patiently responded to questions from us (we’re DIY’ers, not professional builders) and offered/provided certifications to revisions we jointly agreed to. Overall, Triple V provided what was promised at an outstanding value."

"Recently I had the opportunity to work with the guys from 3D Designs and Floorplans. My project was something very unusual, because I needed to build a clothes hanger rack in my new van for my mobile Dry Cleaning and alteration business. I draw myself some sketches and I explained what I want and they took over my project right away. Besides that I received the plan with all the measurements and details exact to a 1/16 in, Vasile , the drafter and 3D modeler created a full 3D image of the inside of the van with the rack mounted. When we decided with the welding company what material we are going to use and sizes, I sent Mr. Vasile all that and he adjusted everything for no extra charge. When the plan was done I received all the files with all the images and plans broken down to each section and precise sizes and measurements. One thing, the welding company thought was a joke and when I gave them the drafts and plans they just ignored the dimensions and rounded up some numbers so the frame of the rack came almost 1/2 in short. Guess what ? It did not match and fit where it supposed to be mounted, so they had to re do all over again to the exact sizes we had on the drafts. The welding technician and his supervisor said:" we never thought that 1/4 in can make such a difference" The experience I had with this company exceeded my expectations and the job was done 150%, top notch. Best affordable prices, no extra charges and great family like customer services. Now I rehired them again to work on my house plan and couple remodels we are planning to start soon, like ad two pergolas over front entrance and in the back over my deck, kitchen remodeling, and a plan for a new storage / working area shed. Amazing work, excellent prices and great ideas. I recommend this company to all my friends, and fellow veterans, since the company is managed by a veteran as well. Plus they do a great job on all VA plans to adjust your home to the disability needs."

Structural Engineering questions, answered by experts

Structural engineers are necessary for projects involving alterations to load-bearing structures, foundation work, and compliance with safety standards. This includes home expansions, retaining walls, and significant repairs that impact a property's integrity.

Dormers must be able to bear the load of their own construction and the added window. The style of the dormer, however, will determine where the weight loads onto your home's structure. A gable dormer bears the weight on the side walls whereas a shed dormer bears it on the front walls.

You should avoid drilling or cutting into load-bearing beams because removing material will weaken it and increase the risk of structural damage or even collapse. If you do need to drill into a load-bearing beam, speak with a structural engineer first to discuss where it’s safest to drill and the width and depth of the bit that’s safe to use.

On average, 6 inches of concrete can hold around 150 pounds per square foot, but the exact weight that 6 inches of concrete can hold depends on factors such as the type of concrete, the reinforcement method, soil conditions below, and structural design. If you’re concerned about the longevity of your concrete patio, walkway, or driveway, hire a professional to help you choose an appropriate concrete thickness and reinforcement method for your needs.

Building codes for spiral staircases will vary by your location. Most local codes will specify minimum tread width, riser height, handrail requirements, and headroom. These standards help ensure safety and accessibility for all users. Always check local codes before you begin the installation to ensure compliance and avoid costly modifications or fines.
