Our firm provides structural engineering support for all phases in the design and construction process. Our primary function is to create structural plan packages for submission to the governing authority. We are also available to conduct preliminary field visits and structural observations during construction. In whichever service you need, we pride ourselves in carrying out the job professionally, quickly, and for an affordable price.

"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!"

"Quoted one price and kept asking for more money. They only came to the house once, and any changes I had to make (because they didn't have all the information) they changed me more."

"The work Erdelyi associates did is great, but communication and timeliness were lacking. I didn’t have a consistent point of contact throughout the project - it just seems my project was handed off from one person to the next with no continuity and I had to proactively reach out for updates."

FAQs for engineer structural projects in Rosemead, CA

The timeframe for installing an LVL beam depends on your project's complexity and scope. Factors affecting the timeline include whether walls need removal, the beam's size, and whether electrical or plumbing modifications are necessary. Your contractor should provide a specific timeline estimate based on your home's unique circumstances and the specific requirements of your installation.

Financing options are available for structural improvements like LVL beam installations. Many homeowners use home equity loans or lines of credit, often offering favorable interest rates for home improvement projects. Some contractors partner with financing companies to provide payment plans directly. When gathering quotes, ask potential contractors about financing partnerships they maintain or recommendations for lenders experienced with home renovation projects.

LVL beams become necessary when you need to span greater distances without support columns or when supporting substantial loads. Traditional lumber can't span more than eight to 12 feet without support, while LVL beams can extend up to 30 feet. LVL provides the necessary strength to create truly open concept spaces or support upper floors without columns. Consulting with a structural engineer helps determine the appropriate beam type for your specific requirements.

Beyond the core installation, the budget for build-back costs totals $400 to $2,000, depending on the extent of affected finishes. If foundation reinforcement becomes necessary, allocate $1,000 to $3,000 per pier. Permit fees ranging from $100 to $500 should also be anticipated. For installations affecting utilities, factor in electrician rates of $50 to $130 per hour and plumber rates of $45 to $200 per hour if rerouting is required.
