About us: "At LEVEL, we are committed to common sense, real-world solutions. We pioneered LEVEL because, after years spent exploring all disciplines of civil and structural engineering in the building industry, we continually encountered the missing fundamentals in our own trade. These lost elements of service culture & exceptional business practice inevitably cost owners & entities untold stress and frustration; contractors lost time & money, realtors & lenders were left unable to satisfy their client's needs. We concluded that our capacity for A&E services could function at a higher level, thus, LEVEL Engineering & Inspections was founded. We serve your interests & provide knowledgeable, expert design, inspections, analysis, forensics, recommendations, and reporting. Whether your need is for permitting, forensics; new, remodel, or repair engineering designs; foundation problems; civil or architecture - let us help you navigate your Civil, Commercial, Residential Structural Engineering needs."
