About us

Hello, my name is Louis Schwartz and I am the owner of Tiderunner Engineering & Design, P.C. I started my civil engineering business in 2004 to focus on the residential construction Industry. With over a decade of experience in the industry I have substantial knowledge in preparing plans for renovations and/or additions. I have also been reviewing plans in Suffolk and Nassau counties for code compliance written by others, structural analysis, and residential sanitary system design. I work very close with both contractors and homeowners and I enjoy supplying engineering support for contractors in the residential construction field. My company has been very successful over the years because I provide such a variety of services as both a structural engineer and a plan preparer. I have helped several residential contractors with building permit application preparation, grading and drainage plans, as well as acquisitions. If you are looking to work with the best in the business; look no further than Tiderunner Engineering & Design, P.C. Call me today to set up an appointment.

Louis was very professional and attentive to details. I wanted him to design an Ibeam for me because I was removing a load bearing wall to have an open concept. I hired Louis because I wanted to have a piece of mind, and he made sure he did the calculation and recommended the exact size beam I should get to withhold the load in the house. I’m totally satisfied and I’m glad I hired him.

You will be impressed with how quickly your home will be evaluated and all of your concerns will be addressed before you utter a word. I am an Engineer's engineer and I was deeply impressed he accounted for storms in my house's history, like Superstorm Sandy 8 years ago.

Knowledgeable professional advice resulted in contractor plans that eliminated the need to apply for a variance, and expedited the approval of a construction permit. Our project is now complete and the the results are outstanding, I highly recommend Tidewater, and will use them again should the need arise.
