GE 271 — Engineering Surveying I

BSc BSc Geomatic Engineering · Kwame Nkrumah University of Science and Technology

Coordinate systems for engineering works: Setting out of engineering works- controlling verticality; setting out invent levels. Mensuration- areas of irregular objects trapezoidal rule, Simpson’s rule, area from coordinates, use of planimeter. Longitudinal sections and cross sections- formation level, calculation of cross-sectional areas- Volumes- the end areas method, the prismoidal method, volumes of large earthworks:- from spot heights, rectangular base method, triangular base method. Balance of cut and fill, volumes from contours. Mass haul diagrams cumulative volumes bulking and shrinkage factor correction. Road surveying:-horizontal and vertical curves types of horizontal curves:-simple curves, compound curves, reverse curves, spiral curves. Elements of a horizontal curves, length of curve , tangent distance, long chord (lc), external distance (e), middle ordinate (m), degree of curve (d) and its definitions using arc or chord. Stationing, solution of a simple curve, location of tangent points on the field and setting out of simple circular curves. Compound curves, reverse curves, transition curves, and super elevation. Elements of curve design. Vertical curves, uses, equation for vertical curves, selection of grades for design, K-values, and its relation to length of curve and grade, elements of vertical curves, setting out of vertical curves
