Land Surveying
Horsley Witten Group (HW) feels that having surveying as an in-house service complements other engineering and wetlands services creating a streamlined process in completing project planning, design and construction. Often times design engineers and other integral personnel are involved with field survey, creating a familiarity of the site conditions that result in a better, more efficient design.
HW has the ability to complete surveys for many types of projects, including; topographical surveys, existing conditions surveys for site development, wetlands delineations, permitting, planning, and feasibility studies, property-line surveys for subdivisions, easement plans, and lot stakings, construction surveys for layout and As-built drawings,
In the field, HW uses total stations and state of the art data collectors which capture field information quickly and accurately. This system produces a quick time frame between field survey and finished plan. HW also has experience in various GPS applications. RTK GPS provides the accuracy of a total station and is effectively used on larger project areas (> 40 acres).
HW also uses a submeter hand held GPS unit for gathering preliminary site information, and locating wetland flags. When project are in planning stage and accuracy is not as critical these handheld units can be a useful tool in determining feasibility.
