Learner Outcomes:

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.

Instruction:

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.

Credit recommendation:

In the lower division baccalaureate/associate degree category, 2 semester hours in Introduction to Surveying (4/16) (4/21 revalidation). NOTE: Course content is duplicative of the Construction: Total System Fundamentals course. Care should be taken to avoid awarding duplicate credit.
