QUANTITATIVE SURVEY OF SEALING MASONRY IN PERFORATED BLOCKS: comparison between SINAPI and quantitative spreadsheet using BIM technology

Abstract

In the civil construction sector, the preparation of construction budgets includes, as a preliminary step, the survey of the quantities of services and inputs. This survey makes use of reference sheets. With the use of BIM technologies this process is optimized, requiring minimal human intervention. Thus, this work aims to comparatively evaluate the quantitative surveys present in the SINAPI reference spreadsheet with the values obtained by extracting quantities from a BIM model. The methodology adopted for the modeling consisted of the study of 28 sealing masonry compositions with perforated blocks present in the SINAPI spreadsheet with the elaboration of families using Revit® software, owned by the Autodesk company. The results indicated that the quantitative extracted from the software present distortions regarding the unit coefficients present in the compositions. It was possible to show that the BIM platform facilitates project activities. However, in order to use the quantitative surveys generated by the software for budgeting purposes using the SINAPI spreadsheet, the modeling must be supplied with the coefficients present in the compositions, eliminating quantification errors and contributing to the quality of the budget.
