"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."

"The process working with Char to develop a set of design plans for my master suite addition has been fantastic. She has worked with me step by step, explaining the process at each point and what I can expect. She also listened to what I was looking for, drew up various designs, and then worked with me on modifications. She was a partner in the process the entire time, not only treating me with respect and professionalism, but talking through options and pros and cons with me so I ended up with the design I really wanted. Throughout the entire process I felt like I was in good and trustworthy hands. So much so that I will continue to use Char's assistance as I move forward on next steps with this project."

"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."

Structural Engineering questions, answered by experts

The average cost to hire a structural engineer is about $550, with prices generally ranging from $200 to $1,500. Structural engineers may charge a flat rate, by the project, by square footage, or an hourly rate, which is typically between $100 and $250. Many jobs, such as inspections and structural calculations, are billed at a flat rate, which often falls between $300 and $800. The final cost depends on several factors, including the project's type, scope, size, complexity, ease of access for inspection, and your geographic location.

Many horizontal cracks in home foundations result from water and soil pressure from outside of the building or from a footing that is shifting. Under those circumstances, horizontal cracks are a structural problem that requires repair before they become worse and more difficult to fix. However, in very specific cases, thin horizontal cracks may simply be a cosmetic blemish due to concrete shrinkage.

Accurate measurements, sturdy materials, and seamless integration with other structures.

Precast concrete can be reinforced with rebar, wire mesh, or other materials to improve its strength and add stability. Precast concrete for large construction projects is often pre-stressed as well for greater structural strength. Reinforced concrete is durable and strong, making it an ideal choice for many construction projects.

It's safe to assume that all exterior walls are load-bearing, or at least have load-bearing characteristics. Some older homes feature porches or bump-outs that don't rest on the home's foundation. However, they still must carry the weight of the roof section they support. Walls containing floor-to-ceiling glass or other non-structural elements must use post and beam configurations to meet load-bearing criteria.
