We used Fredy to help remodel our 100 year old beach cottage. It needed to be retrofitted to withstand an earthquake some other minor details Our initial meeting went great I thought. We laid out what we wanted and Fredy told us what we could and couldn't do. He told us he could have the plans done pretty quickly and we were happy with how it was going until.. We wanted to add a skylight and asked Fredy about it. He quickly said we couldn't and gave no real explanation why. So we did a little research, asked another engineer and found out it was possible. When we called to ask Fredy about it he YELLED AT MY WIFE and basic said not to question him. It seemed Fredy didn't want to do the extra work to look into it. He ended up adding it after I had another conversation with him. It's not over.. Once we finally get the plans and turn them into the City for review they get sent back to us. FREDY MESSED UP NORTH AND SOUTH! It then took him over 2 weeks to correct it! THIS COST US OVER 10K DOLLARS because the project was held up and we had to keep paying the mortgage FREDY MESSED UP OUR PLANS 2 MORE TIMES AND COST US OVER 20K DOLLARS IN MORTGAGE PAYMENTS AND MONTHS OF IDLE TIME Please don't be fooled by the 5 star reviews. If you are in the market for a good, timely and competent engineer I suggest you look elsewhere. read more

Fredy did a great job with the plans for a 525sq ft addition of my house (master bedroom extension, new bathroom, additional hallway. He and Nanak were very easy to work with and responsive. He was very open to helping me conceptualize what I wanted; he offered great suggestions and options for me to choose from. They delivered plans within their estimated timelines. I went through 4 bids, and his agreement was fairly priced. I am grateful for him putting together a master plan for us and looking forward to the build. read more

Fredy and Nanak are a great team. I reached out to them because of their positive Yelp reviews and I'm happy I did. They were very responsive, made payment easy, and provided a nice detailed report along with detailed pictures. I will definitely be reaching out for my next structural engineering needs! read more

The team at OConsulting were very professional and helped me get the needed plans with many revisions to satisfy the City in order to obtain permits. I highly recommend this business for your architectural design needs. read more

Fredy is truly great! He is super reliable and on top of his work! He is also very knowledgeable on his fields! Had such a positive experience working him! Oh, forgot to mention, he is also very easy to communicate with! I definitely recommend him! read more

I reached out to several structural engineers to get plans for removing an interior wall in my home. I received mixed answers and drastically varying quotes. I paid one a few hundred dollars to come out and spend 5 minutes in my attic to tell me my wall was load bearing and it would cost $4k for plans. It didn't sit right with me and on a whim, I decided to reach out to Fredy even though he had fewer reviews. I'm SO glad I did. Fredy came out in person and after spending a bit of time looking in the attic, concluded that the wall was NOT load bearing. He even had me come up there so he could show me exactly why it wasn't. On top of that, his pricing was extremely reasonable. We received plans exactly when he said we would and was available to answer any questions that came up during the process - we've now successfully completed our project. I am so happy I stumbled across Fredy's page and would happily refer him to friends and family. read more

I worked with Fredy recently for plans for a whole house remodel. I spoke to 4-5 engineers that had either been recommended to me or I found via yelp & selected Fredy as he took the time to understand my project, walk me through the process and answer any questions I had prior to me signing a contract or him taking any payment for a consult. Fredy came out to the home himself to walk through the project & take measurements. The plans were delivered ahead of schedule and when revisions were needed he scheduled time to understand the needed edits with me via zoom. OConsulting were a pleasure to work with. They were not the cheapest, but for the piece of mind of quality work and dealing with nice people I felt well worth it. I highly recommend OConsulting to anyone needing their services. read more

Had never needed the services of a structural engineer before and found OConsulting here on Yelp. Nanak who has excellent skills dealing with people and connected us with the engineer Freddy to help us with the inspection of a load bearing wood beam. Freddy was right on time, very skillful and knowledgeable and was even able to help us with a related but side project question which was very helpful. Great service for a very fair price. Absolutely recommend OConsulting. Give them a call. read more

Fredy exceeds expectations. His structural knowledge and professionalism is fantastic. Great value for the cost. Would hire him again.

Thank you Fredy for taking my call! I really appreciate the time you took to provide me high level advice for my situation. With being such a busy time of the year for construction projects, I just wanted to say "thank you" for your time and kindness. read more

I would (and have) recommended Fredy to anyone in need of an engineer. I used him on a seemingly never ending residential remodel where we removed some interior walls. I have had to "bug" Fredy one a week, minimum, over the past couple months about various things that have come up on the job and he has been very quick to respond and has been an invaluable part of our remodel. He was also really helpful in recommending other contractors to use throughout the project. A true delight in every way! Don't let the single ridiculous 1 star review someone felt the need to write simply because the mailbox was full when they called one time deter you from using Consulting services. Worth every penny and then some! read more

I can't share any info other than I got a voicemail of a guy named Freddy and his mailbox was full. Not very professional in my opinion. Maybe he doesn't need the work... maybe he doesn't return calls... Idk read more

Where to even start? Fredy Orellana is fantastic! When looking to install our bifold doors, I talked to several engineering/architectural firms and ran into estimates that were thousands more, or people who didn't really seem excited to take on a "smaller" project like ours. As soon as I spoke with Fredy I knew he was the right choice. Over the course of a few months, he drew up full plans for our home, created all the engineering calculations and specs for our door install, and was there with a solution and quick turnaround for any issues that came up as we implemented the install. Did I mention my home is on a sloped lot with different elevation points, and had an addition room that was different from the rest of the home? Fredy took it all in stride. He was so amazingly easy to work with, and he's a great person. Hire him, you won't regret it! read more

OConsulting - Fredy's plans and calculations were crucial for the structural component of our door install. We love how it turned out! - Structural Engineers Near Me - Irvine, California

Freddy was super helpful with a last minute question about a property I was considering purchasing. He answered right away and offered his expertise that ended up saving me a lot of headaches. Definitely recommend! read more

I sent OConsulting and three other structural Engineers information on my room upstairs to determine whether it can support a home gym. Oconsulting quickly replied with the answers I needed to determine whether or not it would be ok without asking me to pay a fee. In today's world that is very rare. Most companies demand payment before they will offer any advice. I highly recommend OConsulting. read more

AMAZING! This was my first time doing an addition to our house and I called Fredy based on a referral from my neighbor. Fredy is nice, professional, caring and true to his word. He came out to the house, even though we are only adding 36 square feet (taking garage space to enlarge the bathroom), he treated me like it was his most important project. He answered all of my questions - I had a few being new to this. He provided all of the needed plans, specs and paperwork and for the best price (I compared 2 other firms). The plans were perfect and the city approved them while I was at the counter - in and out. After getting the plans approved, Fredy was there to answer follow up questions that my contractor had too. I will be using Fredy on every project moving forward and referring him to anyone needing his services. read more

I sent a request to OConsulting for some structural consulting work at my home. I heard back very promptly with an honest and detailed response from the owner. All the other companies I reached out to wouldn't provide any detailed info without an in home consultation. OConsulting was a breath of fresh air! read more

Wow! I recommend this place to all my friends and family. I have dealt with other companies and no one has been as helpful as Fredy and his staff. I was put through hell with the city of Jurupa Valley, but Fredy was beyond accommodating. He always responded promptly and mailed corrections as requested. I have had nothing but a positive experience with this company. In good hands. read more

Honest Structural Engineer! I sent a photo of a structural beam for evaluation and ask him to come to my residence for further inspection. Freddy told me that he was able to give his professional opinion from the photo and said he didn't need to come out to just take my money. Not a lot of honest and good karma people left out there. It was refreshing to cross paths with one. read more

Fredy is an incredible professional. My agent helped me find him for an urgent structural review needed in my garage as my house was completing escrow. Out of five engineers consulted, Fredy was by far the best communicator, provided options and ideas that others did not even mention, had my interests and cost savings at the forefront, provided extremely fast turnaround on his calculations, paperwork and design drawing. It accomplished exactly what it needed to, and much faster than anticipated. Besides all of that, Fredy is really just a fantastic person on a human level. So easy and great to work with. I could not recommend anyone higher. read more
