Abstract

In the early stages of housing project planning, the project owner requires an initial cost estimate as an estimate in determining the value of the investment. For that we need to develop a cost estimation model that is more precise,easy to use, and can be justified. Cost Significant Model is one method of estimating the cost of projects that have been widely applied with fairly accurate results according to some previous research. This study aims to develop estimation model in the early stages of housing project planning in Surabaya, Gresik and Sidoarjo. The development method uses the principle of "Cost Significant Model" and multiple linear regression equation. The data were taken from 8 simple housing project packages using Bill of Quantity method from fiscal year 2012 until 2016 then compared with 1 work package to be implemented. The results concluded that the cost significant item of 85, 78% consists of work: roof and ceiling (X6), painting (X8), sanitation and channel (X11). Cost estimation model of housing development using cost significant model obtained equation Y = 1,782,020.22 + 0.893 X6 + 4.479 X8 + 4.675 X11
