Graves Engineering performs detail and topographic surveys for most our engineering projects. This work is performed in the field utilizing a total station with electronic data collector and/or a GPS/GNSS receiver. The field data is then reduced and imported into an AutoCAD electronic drawing. The three dimensional survey points are then used to create an existing conditions site drawing complete with contours.
We also perform construction control layout for footings, foundations, building column lines, site utilities, parking lots, roadways, retaining walls, stormwater detention/retention systems, and more.
