NCCER SURVEYING SITE LAYOUT
EXAM QUESTIONS AND ANSWERS
Backsight - Answer-when measuring angles, the sight taken with the instrument or line
being used as the starting point.
benchmark - Answer-permanent reference point with a precisely determined elevation
datum - Answer-permanent horizontal & vertical reference for a project.
relief - Answer-the difference in elevation between the highest and lowest parts of an
area
traverse - Answer-measurement of a continuous series of angles or distances
Control surveys - Answer-Establish a network of horizontal and vertical monuments that
serve as a reference framework for initiating other surveys.
preliminary surveys - Answer-used to locate existing natural or man-made features
Longitude - Answer-distance north or south of the Equator, measured in degrees
latitude - Answer-Distance east or west of the prime meridian, measured in degrees
Prime Meridian - Answer-The meridian, designated at 0° longitude, which passes
through the Royal Observatory at Greenwich, England.
International Date Line - Answer-An arc that for the most part follows 180° longitude,
although it deviates in several places to avoid dividing land areas. When you cross the
International Date Line heading east (toward America), the clock moves back 24 hours,
or one entire day. When you go west (toward Asia), the calendar moves ahead one day.
RAPS - Answer-one or more control points on or off the site. (Shell station)
primary control points - Answer-secondary network of control points
secondary control points - Answer-stakes set out by contractor to aid in construction
Building layout/work control points - Answer-locate corner of building
Control points - Answer-avoid abbreviations or use standard abbreviations on control
point. all sides can be used. put down alignment info, center line, elevation, description,
grade, offset, etc
Philly rod - Answer-two sections 13'
