The plans included caissons, structural beams and slab, with void-forms to address problems with expansive soils. Despite coming in a bit behind schedule, the Prostruct plans were in such good shape that there were no go-backs or comments from the Building Dept so that the permit issued quickly and work started back on schedule. Prostruct also then supported the caisson and form inspection with the required "Engineer's' Letter." Thanks Prostruct! Well done!

I would not recommend Liftech based on my experience. The biggest concerns were the lack of proper…read moresubgrade preparation, the lack of transparency, and the difficulty getting clear, consistent answers throughout the process. I specifically chose and paid extra for high early cement because my goal was to regain access to my garage parking as soon as possible. I expected clear guidance on the product's performance and realistic timelines. Instead, I received conflicting information ranging from not being able to walk on the concrete for 48 hours to not being able to park on it for anywhere from 2-10 days. When I asked for clarification, the responses were vague. Liftech's production manager stated, "There are no specific specs for high early since it is mixed with concrete at the plant," and also said, "There is varying information because no concrete is created equally." I would expect concrete professionals and concrete plants to have more consistent information regarding the product being installed. Another major concern was the subgrade preparation. Liftech subcontracted the concrete work, and when the crew arrived, they did not even have a compactor onsite. I asked the workers if they planned to compact the subgrade, and based on their responses and actions, it did not appear that proper compaction was part of their plan until I contacted their Project Manager and requested that a compactor be brought to the site. A video documenting the work can be viewed here: https://youtu.be/YBubb-Wx-ac. In the video, it appears that only about 50% of the area was properly compacted, with some areas not compacted at all. The subbase also does not appear to have been watered down as part of the preparation process. The video speaks for itself regarding the preparation that was completed before the concrete was poured. For a project of this size and cost, I expected better communication, transparency, and attention to detail. Unfortunately, my experience left me questioning both the workmanship and the information provided throughout the process.

He would stop by when requested by the building department's inspectors. He also provided certified letters for me to upload to my permit for the inspectors' review. I will definitely reach out to John when I'm ready to do other major home-improvement projects that will require architectural & structural designs for the permit application process.
