Tiderunner Engineering and Design PC

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.

Mr. Schwartz arrived on time, and provided a thorough examination and assessment of the foundational errors that exist in my reconstructed post-Superstorm Sandy home. He spent much time explaining the soil report and how to interpret it, and going over the blueprints for the house. His report arrived 2 days later. Overall, he was very professional and I would recommend him to anyone requiring the services of a design engineer.

I had to remind the engineer several times during the course of 1 1/2 weeks what I needed done. He seemed preoccupied with other things.

Fine job.

I wanted an engineer to size a structural beam and the supports needed to hold up the beam in my ranch. I sort of knew what needed to be done, but I wanted a pro to take a look. Lou came right down and was in and out in a few minutes. He answered all of my questions and emailed a digital report in a timely manner. A quick $400, but worth the expense knowing that a professional approved my project.

What is the screening process that Service Professionals go through in order to become members of the HomeAdvisor network?

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.

    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
  7. Legal Search for Civil Judgments
