, Outline
❑ Calculation of Areas
❑ Earthwork Computation
Reference book; figures are obtained from (unless specified):
J Uren; W. F Price (William Frank), Surveying for Engineers, 5th ed. Basingstoke : Palgrave Macmillan 2010
, Learning outcome
• Knowing the methods to calculate areas of irregular shapes,
sizes of parcels of land
• Learning the methods to calculate volumes of
material/soil/earthwork
• Transfer the above knowledge to solve other problems

, Areas Enclosed by Straight Lines
• Areas from Triangles
– straight-sided figures can be divided into well-conditioned triangles
