Techniques for measuring distances, relative heights,
and angles have improved significantly during the last
decades. Some of these techniques can be used in the
Architecture, Engineering, and Construction industry to
improve the precision of measurements being made
currently using traditional equipment. Other techniques
can be used to record information that could not be
obtained practically using the traditional equipment.
Cost comparisons are made for different scenarios to
show that the substantial initial cost of the new
hardware can be compensated for by lower labor cost and
shorter duration. This paper also points out some of the
salient features of the new metrology options. For
example, locating the three-dimensional coordinates of a
point is necessary for robotic control. In this case,
new equipment must be used if the traditional equipment
cannot obtain the coordinates at a rate that is useful
to control the movement of the robot.
