Perform surveys for determination of existing land contours, and structures for design and construction purposes. The horizontal control for most surveys is the North American Datum of 1983. We utilize Trimble Global Positioning System Receivers and Topcon total stations which are used for horizontal control. The vertical control for most of our surveys is the North American Vertical Datum of 1929. We will use the North American Vertical Datum of 1988 if it is in the area of our survey.

Types of Surveys Performed:

-  Conventional survey with handwritten notes showing the existing topographic    features and levels performed with an engineering level, i.e. self-leveling direct    reading level.

-  Electronic data collection survey with Topcon Total Station. The information    collected will be broken down on TDS and Microstation/Eagle Point Software.

-  Aerial survey with the aerial targets set at predetermined positions.

-  Perform precise levels in areas where there are problems with settling or the    bench mark control is poor.

-  Perform replacement bench mark work if a bench mark is going to be destroyed.    Perform Monument Inspections of Tract Maps and Parcels Maps.

-  Perform extensive Global Positioning System surveys with other agencies, federal    government, and various colleges and universities.

Perform Construction Surveying for the Following:

-  Road construction stakes: Slope stakes, various grade stakes, Con stakes, curb    stakes

-  Utility stakes

-  Structure stakes

-  Bridge staking

-  Railroad track staking

-  Elevations of existing ground before and after construction to determine    quantities Flood control channels, ditches and catch basins

-  Monumentation

-  Perform Quality Assurance surveying for inspectors on projects to assure the    construction stakes of others were set within the accuracies necessary for the    task.

-  Perform property surveys and setting property corners.
