"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."

"The project went great. Peter is very professional, super knowledgeable, responsive and timely. The plans were done on time and there were no problems with the city review. They answered the questions the contractor had during the construction. Couldn't be happier with the whole process. I thought it would be more difficult than it was. Thanks to Peter and his team we feel very safe with the new addition. We are planning on putting a second story on our house (when we can afford it) and we will absolutely use Peter.

"Eran quickly responded to my inquiry regarding a load bearing structure of my home. He sent his structural engineer to determine if the structure was a load bearing problem. The engineer was able to determine 100% that it was not a load bearing structure. I would definitely recommend them to anyone who needs structural engineering solutions."

"I was referred to 800 Remodeling by Angie's List, and the owner, Amir, called me literally minutes after I received the referral. I described my situation to him and we scheduled a meeting at my home for the following day. He arrived promptly and immediately introduced himself with a picture ID and his state contractor's license. After inspecting the cracks that were of concern to me in a structural post supporting a major beam, he took some pictures and promised to get back to me with some recommendations. The next day, he called just as he had promised, told me that after talking with a structural specialist he did not believe the post needed to be replaced, but nevertheless gave me a rough-order-of-magnitude estimate on what a replacement would cost, should I decide to have that done. After some additional research, I concluded that the cracks are typical and not impairing the structural integrity of the post, and decided for added insurance simply to reinforce the post with some wrap-around steel bands. Since that is a small and simple job, Amir offered to refer me to someone else to do that job for me. He did not charge me for the consultation or the time he spent in discussions with other specialists. So although I ultimately didn't hire him for this job, I was impressed by his professionalism and shall definitely be contacting him again for some larger jobs I am planning in the future."

Structural Engineering questions, answered by experts

Homeowners in Pasadena often underestimate the impact of local soil conditions, especially when foundation repair or seismic retrofitting is needed. The time required for city permit reviews, utility coordination, and compliance with historic preservation guidelines can also be overlooked. Additionally, seasonal weather and the availability of specialized materials can unexpectedly extend project timelines, making careful planning essential for a successful outcome.

Helpful?

Signs of thorough structural engineering in Pasadena include detailed, stamped structural drawings, comprehensive seismic calculations, and documented approval from city inspections. On-site, expect to see quality materials suitable for the local climate, secure foundation work tailored to Pasadena’s soil, and robust seismic connections. Complete inspection records and clear communication from your structural engineer also indicate a job done to high standards.

Helpful?

To ensure a smooth structural engineering project in Pasadena, begin by reviewing local building codes and determining if your property is within a historic district. Schedule a pre-project consultation with city staff, arrange for a geotechnical assessment, and coordinate with utility providers early. Notifying neighbors when required and allowing extra time for the city’s plan review process can also help prevent delays and keep your project on track.

Helpful?

Watch for quotes that skip a site visit, lack mention of Pasadena-specific code compliance, or ignore the need for permits. Be wary of professionals unfamiliar with local seismic requirements or historic property considerations. Vague communication, missing references, and failure to address foundation assessment or soil analysis are also warning signs that the structural engineering professional may not deliver reliable results for your project.

Helpful?

Completing structural engineering projects in Pasadena offers immediate benefits like improved safety and smoother permit approvals, especially for earthquake-prone areas. Over time, your home gains increased structural integrity, better protection against wildfires and weather extremes, and enhanced property value. These upgrades also help maintain the historic charm of older homes and reduce the likelihood of costly foundation repairs or structural issues in the future.
