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!"

This was a no brainer in choosing him and Decoland to do my backyard. Anyone looking to do landscaping and/or any house remodeling should definitely look into using him.

"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."
