This
course is divided into four (4) parts:
Part
1: Basics of Surveying – Basic concepts, measurements of distances and
angles, types and classes of surveys, surveying instrumentation, methods of
linear measurement, types of measurements, chains, tapes, standard conditions
for use of steel tapes, taping accessories and their use. General principles of EDMI operation, level,
theodolite, total stations. Field
procedures for total stations in topographic surveys, surveying applications,
and field notes.
Part 2: Measurements and
Computations: Units of measurements, Methods of linear measurement, types
of measurements. Horizontal angle,
horizontal distance, vertical angle, vertical distance. accuracy and precision, errors and mistakes,
accuracy ratio, stationing, location methods, accuracy and precision, errors
and mistakes, accuracy ratio. Measure
horizontal distance, Identify and use different measurements, identify equipment of horizontal measurement,
Identify the sources of errors and
corrective actions
Part
3: Leveling: Definitions, types of leveling staff, leveling operations,
techniques of leveling, benchmark.
Leveling (vertical control survey), profile and cross-section leveling,
reciprocal leveling, peg test, errors in leveling, contours and their
characteristics, various methods of Contouring.
Contour intervals, spot elevations, contour properties, locating
contours, existing and proposed grading plans.
Examples of leveling and calculations.
Angles and Directions: Horizontal and vertical angles, meridians,
types of horizontal angles, azimuths, bearing, relationship between bearings
and azimuths. Reverse directions, azimuth and bearings computations, magnetic
declination, types of compasses.
Part 4: Traverse
Surveys: Open and closed traverses, latitude and departures, computation of
error of closure, and the accuracy of a traverse, traversing with total station
instruments. Rules of adjustment, effects of traverse adjustments on the
original data, computation of omitted measurements, area of closed traverse
methods, use of computer programs. Calculations
and examples for traversing, area, angles, bearing, and distances. Calculations
and examples for traversing, area, angles, bearing, and distances. Construction Surveying: Learning
Objectives, Introduction, Setting out a Peg on a Specified Distance and Bearing,
Setting Out Small Buildings, Sewer and Tunnel Construction, Exercise.
