Get matched with top architects/engineers in Discovery Bay, CA

"Very honest engineer. He performed a mandatory seismic inspection that was required for the city of Hayward. There was no foundation issue whatsoever. Before Mr Padir did the inspection I had a retrofit company look at my building and they told me it would cost $58k to fix the problem and I almost fell for it. It turns out that one joist was rotten from a sewer leak that was repaired. It is hard to find honest people these days. I am so glad it is only a cosmetic fix and a sister joist installed next to it to relieve the pressure on the building. Thank you once again Mr. Padir. Excellent job and quick turnaround."

"Shilpa working with her structural engineer completed all the architectural and structural plans and calculations for a 400SF single story addition, complete with drilled piers and grade beams, in just over two months for submittal to City for review. Shilpa is very easy to work with and is quite readily available to fit my work and project schedule. Shilpa is very responsive to my comments and timely completion of required documents.
