"Erinn was my initial contact and he gave a very through and fair estimate. We had structural work done to support floor joists and large beams under the garage that needed replacing. Ernesto and his team, Julio, Salvatore and Gilder worked tirelessly to complete the work and were respectful, punctual, informative and good humoured throughout the entire process. I would not hesitate to use them again or recommend them to others. A really great company!!"

"Structural Engineer Ehab contacted me about my residential property inquiry. He had already reviewed my property and the general situation I was inquiring about when I called him back. We spoke to me about his concerns with the project and answered all my questions over the phone. He was excellent to work with. Professional & Knowledgeable. Would highly recommend reaching out for technical issues concerning residential engineering. The reason he wasn't hired was that he provided feedback that dissuaded us from taking on a costly project that would not have achieved our stated goals. I will definitely reach out to Ehab in the future prior to beginning any major residential addition or remodel."

"Raj, is a stand-up guy full of integrity. We needed Structural Engineering Design and Calculation services for a retaining wall in our backyard- the wall is neighbor adjacent and retaining a slop, and would exceed 75LF in length and 4FT height. It needed to be designed thoughtfully; And we needed it to be prepared and presented to the City for a Building Permit, so it also had to adhere to our city's unique municipal codes and ordinances. And we needed it done ASAP. Raj, took the challenge and delivered! Raj, came over immediately, he worked over the weekend for us, and delivered all the necessary designs, calculations and drawings, such that it can go to the City by Monday morning. All while putting up with our countless questions, emails, and phone calls. And of course the Engineers at the City Planning & Building Department granted the permit without hassle. His patience, professionalism, and calm demeanor is why we will call Raj again for all of our Engineering needs in the future."

"We recently added a full master suite and a new retaining wall at ground level of our existing home. We interviewed several contractors and decided on Shenon Construction to build our addition. Tom Shenon is the principal owner and licensed general contractor of Shenon Construction. The estimated costs were reasonable and within our budget, and Tom worked with us to keep our costs down without sacrificing quality. More importantly, we felt a connection to Tom Shenon, as he is sincere and honest, but knowledgeable and professional in his approach to our needs. The work is now complete, and we are entirely pleased with the outcome of our new addition. Needless to say, the process of adding nearly 400 square feet to a structure, especially in Southern California, is a very complicated and detailed endeavor. There are many strict building and environmental regulations and permitting requirements set forth by numerous governmental entities, as well as homeowners association requirements that we had to navigate. The difficulty of getting through architectural planning, engineering, and city permitting was compounded during the COVID pandemic, but Tom and his design/architectural/engineering team did an excellent job to design our project and guide us through the processes and procedures necessary to complete the process timely and thoroughly. He is a competent contractor and knowledgeable in his field. He allowed us to select and purchase all owner-supplied fixtures and materials ourselves, or use his design and supplier team to obtain required items at the best prices. We used a mixture of contractor-recommended suppliers as well as obtaining our own selection of items based on our personal preferences. All of the subcontractors, project supervisors, and trade craftsmen were superb. They were courteous and respectful of our property, trustworthy, and extremely skillful in their trades. The craftmanship is amazing and resulted in a beautiful, comfortable addition. All the suppliers and subcontractors used by Shenon Construction went above and beyond to help us obtain needed items at reasonable prices in a timely manner. Based on the results of our project, we feel we definitely made the correct choice in Shenon Construction to complete our addition, and we consider Tom and all the craftsmen involved in our project to be long-term friends. We have no regrets, and we look forward to living in our lovely remodeled home."

"We had our 30+ year-old deck rebuilt, and the experience was fantastic! From the start, the team worked closely with us, patiently refining designs and offering expert advice. Once finalized, they got to work right away, building a rock-solid structure designed to last for decades. They used high-quality materials, secured it properly, and even added custom dog ramps for our pets. The finished deck is beautiful—exactly what we envisioned. The team was professional, efficient, and a pleasure to work with. Highly recommend!"

FAQs for engineer structural projects in San Dimas, CA

To determine if a wall is load-bearing, start by checking your home’s original plans or asking a structural engineer. Exterior walls always carry weight, but interior ones only do if they sit over a beam or run perpendicular to floor joists. If a wall lines up with posts in the basement or falls directly under the roof ridge, assume it’s load-bearing and call a professional before attempting to remove it with a sledgehammer.

Calculating the wall load and sizing the beam must be performed by experts to ensure structural safety. You need a structural engineer to evaluate all load aspects and determine the proper beam dimensions. A professional engineer performs precise calculations and advises on any necessary enhancements, such as larger footings for support. An inspector then verifies that the revised structure meets all safety and code regulations before the finishing work begins.

Hiring a structural engineer is essential for ensuring your home remains structurally sound during any major renovation. Their responsibility is to deliver expert assessments and design recommendations for load-bearing modifications. The average cost to hire a structural engineer is $500, with rates ranging from $350 to $800. Consulting a licensed, experienced engineer guarantees that every structural project, whether constructing a new home or remodeling an existing one, is completed safely and efficiently.

Almost all load-bearing wall removals require a permit as they support everything above it, and building departments want proof that the new beam can handle the weight. Pulling a permit triggers plan review and inspections that confirm the work meets local code and safety standards. Skipping this step can lead to fines or being forced to rebuild later, so have your contractor pull the permit before work starts.

Removing a load-bearing wall to create an entrance for a carport or covered patio is a task that comes with defined cost implications. This modification requires extra structural adjustments to ensure safety and proper integration with the adjoining space. When you convert a wall into an entryway, you can expect to pay between $3,200 and $9,500, with an average cost of $6,400. The additional work required for this conversion reinforces the home’s integrity and ensures compliance with applicable building codes.
