"I searched many and started off with others and nobody came close in handling what we needed.

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 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."

"Satisfied customers reporting! We're writing this review four months after the completion of our bathroom renovation. We've been thrilled with the final product and the experience of signing with Ouri from day one was a pleasure. This was our first large project and we would undoubtedly hire Ouri again. Project We instinctively knew Ouri was the best fit for us after the on-site consultation. Not only are his reviews overwhelmingly positive, but he's knowledgeable, respectful, patient, and honest, with competitive pricing to boot. He's also a very responsive communicator. We needed some time after signing the contract to shop for materials. Ouri kindly rolled with our uncertain timeline, checking in periodically without any pressure to see where we were at and advising on any questions we had along the way. From the beginning of the project, his crew was respectful, clean, and always checked in with us as any questions came up. The project went smoothly and for one very minor hiccup that came up, Ouri & crew were quick to address without question. And months later, he sent a member of his crew to come troubleshoot something minor, again without any hesitation. It's challenging to keep these brief when you have such a great experience, especially when you read and hear about horror stories from other people. Selfishly, maybe we should keep this to ourselves so he isn't so busy when we need him for another project in the future :) Scope The bathroom was totally gutted save for some sections of drywall. A full tiled shower with a bench was installed (replacing a tiny old corner unit!), along with added lighting & exhaust fan, new floor tile, and all new fixtures/ cabinets/ paint. The plumbing and the shower drain were relocated. An old window was removed and replaced by a new one on an adjacent wall."

Engineer structurals FAQs
Look for walls that run perpendicular to floor joists, directly above foundation walls, or other walls stacked above them on upper floors. Walls with large beams or posts are load-bearing. However, visual inspection alone isn't always reliable. The safest approach is to consult with a structural engineer or experienced contractor who can examine your home's construction, possibly review building plans, or perform small exploratory openings to make a definitive determination.
Most municipalities require permits for wall removal, especially for load-bearing walls. These permits ensure that structural changes meet building codes and safety standards. Even non-load-bearing wall removal might require permits if electrical or plumbing modifications are involved. The permitting process includes submitting plans, paying fees, and scheduling inspections. Working without required permits can result in fines, complications when selling your home, and potential insurance issues if problems arise later.
A non-load-bearing wall removal project might take only one to two days for demolition and basic cleanup. Load-bearing wall projects require three to five days or more, depending on the complexity and need for structural support installation. The timeline will extend if your project involves rerouting utilities or extensive finishing work. Larger projects in multi-story homes may take up to two weeks to complete. Additionally, obtaining permits can add several weeks to your project timeline before work begins.
