"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 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!"

Structural Engineering questions, answered by experts

No, a structural engineer is not the same as a builder. A structural engineer is an expert in all things related to the structural integrity of a building. The structural engineer is responsible for calculating the correct materials in terms of load-bearing capacity and overall structural safety. Structural engineers do not perform the actual building of the house or other structures. Rather, the builder executes the plans and designs specified by the structural engineer.

Because of their composite structure, cutting or drilling LVL beams can compromise their integrity. We strongly advise contacting a general contractor or structural engineer before making any alterations to LVL beams. Professionals can also answer questions about choosing between a pier and beam versus slab foundation when designing your project.

By careful planning and reinforcement to maintain structural integrity.

Yes, unresolved damage can decrease property integrity and market value.

A structural inspection report will include a detailed description of the structural engineer’s findings, applicable photographs, and recommendations to correct the issue. The contents of the report may depend on the scope of the inspection but might also include a time and cost estimate for recommended work to correct any structural problems found during the inspection.
