Accuracy in surveying is essential because other engineering factors that are involved after the survey is
complete depend on the surveying results. Construction surveys deal with determining the relative
positions of points on the earth's surface. These points are used to locate and lay out roads, airfields, and
man-made structures (such as buildings, sewer lines, utility lines, and any type of proposed or existing
structure). Construction surveys also identify terrain features that are used to draw large-scale maps.
No matter what type of survey is needed, some type of surveying equipment will be required. Each
surveying operation requires certain specific types of equipment. These surveys can vary in many ways,
depending on the technical requirements needed. This lesson will familiarize you with the surveying
equipment that you will encounter in the field.
PART A - UNIVERSAL SURVEYING INSTRUMENTS
5-1. Tools and Devices. Primarily, the surveying instruments that you will be using are precise tools
with which measurements are made. Many of the instruments have similar features. These instruments
Tripods to hold the instrument steady at a convenient height.
