Survey control establishment is one of the most important and critical tasks to carry out to ensure that a job will be completed accurately and within the design constraints. Poor survey control can lead to some costly and inaccurate survey results on any job, large or small.
Once survey control is established accurately, repetitive and accurate set-out and as-built information can be provided. This also allows the surveyor responsible for the control to place marks in key locations across a job site. Having accurate and well placed control marks will enable a fast and coordinated setup. This in turn will increases productivity and can save the client valuable time and survey resources on a job.
