Abstract:
Project cost estimates must be prepared before the project is implemented. The model for estimating the total cost of
construction using the Pareto principle from past cost data is called the cost significant model.The purpose of this
research is to apply the method of cost significant models to a building project to determine the initial cost of a
building project. The estimated cost per m2 model is Y = 11.564 (X3) + 2949750.72, where X3 is the cost per m2 of
foundation, sloof, and floor work. The accuracy of the Cost Significant Model ranges from -9.4% to 4.8%. This
estimation model is feasible to be used to check the estimated offer.
