Abstract

Paper presents a Geographic Information System (GIS) based quantity takeoffs methodology, which is helpful in increasing the productivity of quantity estimator by reducing the manual work in quantity takeoffs. Proposed methodology also reduces the missing or duplication of various items of work by visualizing each components corresponding to the items in space. Several scripts developed within ArcView3.2 were used to extract the necessary dimensions from the drawings and to perform various calculations for quantity takeoffs. Accurate Bill of Quantities (BOQ) may be generated on the basis of dimensions of various data themes in GIS.
