Surveying is the technique of measuring to determine the relative positions of points above, on, or below the earth’s surface. Surveying is as old as civilization. Its origins can be traced back to the Egyptians who utilized surveying to reestablish property after flooding by the Nile River.
The Survey Section of the Design Divisions is composed of two four person crews who have the responsibility of providing any surveys necessary for maintaining and updating of Henrico County’s roadway and drainage systems. These surveys include topographic surveying, boundary surveying, construction stakeout, construction surveys and geodetic surveying.
As an integral part of Henrico County’s Geographical Information System (GIS), more than 140 high accuracy survey monuments were installed throughout the County to support GIS. These monuments measure 6″ x 6″ x 3′ and are made of reinforced precast concrete with a brass cap. Stamped in this brass cap are the words, “Henrico County Monument”, the year of installation and a unique identification number. You can see more information on Monumentation, here.
