Who We Are

Precision Land Surveyors was founded by David Hembd in 1988. David started surveying at the age of 14 on weekends, holiday breaks and summer vacations in 1972 and has been fortunate enough to have worked on many prominent projects, both domestic and international. These include first order traversing and elevations for over 70 monuments at O’hare Airport, mapping an enormous amount of Northern Illinois. Building bridges, Tunnels, Buildings, Subdivisions, Highways, Railroads, Navy Pier Expansion, McCormick Place expansion, Fermi Labs NuMi project and Traditional boundary surveying. Our key employees have all been with us a minimum of 17 years to as much as 29 years. This shows, not only our dedication to them, but their dedication to the company and our clients.

 

These are the services we currently provide:

  • Civil Engineering - We began our Civil Engineering division in 2003 when we hired Dai-Min Lin. Dai- Min is a Engineering graduate of Oregon State with an emphasis on Structural Engineering. Dai-min originally came through the ranks of Heavy Highway Morrison-Knudsen. He then worked for several very large Joint Ventures before he settled in Deer Park, Illinois. We since have been involved in many residential, commercial and public projects.
  • FEMA Elevation - We perform FEMA Elevation Certificates and Letters of Map Amendments for flood insurance reduction and property development.
  • Preconstruction Videos - We record and produce videos for preconstruction records of construction activities.
  • Erosion Control inspections - Teratek/PLS has two certified employees for performing Erosion and Sedimentation control of Construction activities.
