The most complicated and time-consuming step in estimating construction costs in determining the amount of material is a calculation of all areas for masonry works involving tedious processes. A simple estimating tool could assist estimators in estimating the amount of materials with reducing working time. The purpose of this research is to study the proportion of the masonry wall quantity to the building’s area and develop an estimating factor to estimate the masonry wall area of two-stories houses in 59 drawing construction for a case study. Using multiple linear regression analysis for independent variables that influence the dependent variable showed that the building area was an independent variable affecting the masonry wall area. The modeling to test, found that the masonry wall area less than the detailed estimation
as 0.50 - 6.78 %. Therefore, the model derived from this research, theref can apply for cost estimation and validation of the masonry wall area calculation of new project quickly.
