Perbandingan Cost Significant Model Dengan Metode Parametrik Untuk Estimasi Biaya Gedung Bertingkat 2 di Provinsi Sumatera Barat
Abstract The estimated cost at the initial or conceptual stage is an estimate made when there is still little information about the image, description and specifications of the work to be done. This estimate is needed to provide information on the initial description of the total construction costs. Estimated costs must be accurate so as not to cause problems in the future. To obtain a method that meets these needs, we compare two estimation methods, namely the Cost Significant Model and the Metode Parametrik. This study aims to determine the components of the calculation needed by the Cost Significant Model and Parametric Method and the comparison of the two in making cost estimates and for determining the most accurate method. This research was applied to the construction of a 2-storey building in the province of West Sumatra. Data related to the study were collected from consultants in the city of Padang with 9 (nine) RAB data complete with project information originating from 2013 s.d. 2016 Based on the Cost Significant Model analysis, the regression analysis formula is obtained: Y = 1,340,187,179 + 3,175 X2 + 0,295 X10 + 7,072 X11 + 1,881 X4 - 4,134 X13, where X2 is Foundation Work Cost, X10 is Wall Work Cost, X11 is Door Work Cost and Window, X4 is Column Work Costs, X13 is Floor Work Costs. This cost estimation model has been validated with an average error percentage of 0%. Metode Parametrik Analysis using the formula set out in Presidential Regulation No. 73 of 2011 Article 14: Total Project Costs = HSBGN x K x Project Area, where HSBGN is the Price of the State Building Building Unit and K is the multiplier multiplier for multi-storey buildings. This cost estimation model has been validated with an average error percentage of 32%. Based on the results of this error percentage, it is concluded that the most accurate method is the Cost Significant Model. To obtain a small earth (near zero) resistivity value is determined by the number of planted electrodes and soil type properties.
