TI  - Development of spreadsheet based quantity take-off and cost estimation application
AB  - Quantity take-off and cost estimation are the most time consuming and costly work items of the projectplanning phase. A structure consists of significantly many components, and quantities of all of these workitems have to be computed as well as necessary workmanship and materials should be determined. If quantitytake-off is computed incorrectly, then cost will also be estimated erroneously. Therefore, computation ofquantity take-off correctly has vital importance. Each constructed structure is unique, for this reason quantitytake-off has to be prepared for every structure. In this study, a spreadsheet application is developed for thecomputation of quantity take-off with minimum human intervention and endeavor. Positions of the loadbearing sections and architectural elements are defined by nodes and dimensions of these elements areidentified by entering related information to data cells. Topologies of the structural and architectural elementsare formed to determine the neighborhood and intersections. Voids are computed and subtracted to obtainexact quantities. Necessary materials and workmanships are determined by using database and cost isestimated by using unit prices of these items. Quantity take-off and cost is computed fast and accurately withminimized data input. Consequently, design offices can avoid purchasing expensive quantity take-offsoftware by utilizing this approach.
