We establish survey control networks which consist of stable, identifiable points tied together by extremely accurate observations. The control stations can be adjusted to millimeter accuracy, which allows for precise stations to be in place throughout the construction activities. The control network can be produced using traditional Total Stations and traverse methods and Least Squares calculations. If the site stretches over a vast area we are able to offer Post processing GPS observations to establish the control network. This can be done to millimetre accuracy by collecting GPS observations using a static receiver. We offer static observation to establish national control networks and even measurement of boundary markers between nations.
