"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."

"I've had the recent good fortune to work with Tolga on renovation projects in Los Angeles and Manhattan Beach for which I am the Architect. The success of renovation work relies heavily on collaborative and creative structural engineering in order to realize interior and exterior architecture goals. Tolga instinctively understood my design goals and in a very professional manner he crafted solutions to bring them to reality. Many thanks Tolga. I look forward to our next collaboration."

"I hired Beginnings Engineering for a structural project on my 45-year-old home and worked with Jonathon Sipe and Nada. I spoke with several other firms in Orange County first. Most of the alternative proposals leaned toward complicated, expensive “perfect” solutions that might make sense on a new build, but didn’t feel grounded in the reality of an older home. Jonathon took a different approach: he listened to what I was trying to accomplish, worked through the constraints with me, and came back with a solution that made sense in the real world—while still being safe and code-compliant. On top of that, the experience was just… easy. Communication was straightforward, follow-through was solid, and they were genuinely friendly people to deal with. They weren’t the lowest engineering quote, but they were the lowest-cost path overall because their design avoided the unnecessary construction scope other firms recommended."

"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!"

"He consulted on the project and gave very valuable information and advice that would ensure that my project was safe and up to code. He was quick to arrange a visit to my site where he immediately surveyed the work - you could see his mind actively engaged😊. He is very professional, personable, and he listens intently, and communicates at a level I could understand. I highly recommend him to diyers and pros alike. Louie"

FAQs for engineer structural projects in Whittier, 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.
