Upon successful completion of the course, students will be able to: describe the difference between a transit and a level; identify three types of advanced layout instruments used; list and demonstrate proper hand signals; identify the components of a field book, and describe the purpose of each; record information in a field book neatly and accurately; identify six tools commonly used in surveying procedures; measure the distance between two points using a surveyor’s tape or chain accurately to within ± /02'; measure from a given point and set a hub on a line; read and set angles on the vernier; given a point, correctly set up and level an instrument over the point; turn angles off of a base line and set new hubs; set up the instrument between two points; define the terms: angle, arc, baseline, chord, contour, diameter, radius, and right triangle; complete basic geometry problems on a worksheet and calculate area and volume for basic geometric shapes; accurately add and subtract angles; find the length of a vareity of objects using both the U.S. standard and decimal systems (80% correct) given common construction measuring equipment; convert measurements given in the standard system to their decimal equivalents; given a hand-held sight level (Locke level) device and a benchmark, find the elevation of various points; demonstrate basic surveying procedures for horizontal and vertical measuring, and controlling elevation with a margin of error not greater than .05" (five hundredths); given scenarios involving station designations on a construction site, calculate distances using station equations; given locations marked on a grid system, calculate their coordinates; explain the difference between in line and right angle referencing; describe the procedure for finding points from offset stakes; describe the procedure for finding both curb grade and top of curb elevation from the offset stakes; given dimensions from two known points, find a hidden point using swing tie referencing; find vertical and horizontal distances to a point from the information given on slope stakes; given a slope stake and the proper tools, set jump stakes showing the correct cut or fill along the slope; explain three types of slopes used on a roadway job and where and why each would be used; explain the procedure for making cuts and fills in a roadway construction project; explain the purpose of grade sheets and how they are used to find elevations for roadway construction; given a problem with earthmoving on a roadway project, find the number of cubic yards of dirt that will need to be cut or filled; given a problem with sub-base fill, find the tonnage of aggregate that will be needed; and given problems with quantities of surfacing material, find the tonnage of asphalt and the cubic yards of concrete that will be needed.

Major topics include the skills, knowledge and aptitude necessary to operate a variety of surveying instruments and to record information for maintaining elevation and alignment control points on heavy and civil construction projects.

In the lower division baccalaureate/associate degree category, 2 semester hours in Introduction to Surveying (4/16). **NOTE:** Course content is duplicative of the Construction: Total System Fundamentals course. Care should be taken to avoid awarding duplicate credit.
