Key to success! The control network establishment survey is a tedious and important process to identify the benchmark position of any particular region or project extent. RVS Land Surveyors with the help of DGPS instruments (Differential Global Positioning System) and technology identifies the key referential benchmark point with data accuracy. The benchmark is the common trustworthy coordinate point important for any project success from the project planning, design, construction, to documentation phases. As the accuracy in benchmarking the project coordinate is the key success to any project, we suggest our clients identify the project coordinate before project commencement to minimize the cost of reworks. Accurate in the benchmark positioning!
