Abstract

Perception data of assessment of contractors’ competency is necessary to be collected from any parties who involve in construction projects in order to improve contractor selection system, not only in the stage of prequalification phase, but also in the stage of tender phase or in the stage of a selection of the winning contractor. To obtain the answer of contractors’ perception in terms of the most to the least important factors of the assessment of contractors competency, a structure questionnaire survey was conducted in Palu, where the sample came from a part of small contractors in Palu. Technical and managerial strength and compliance with regulations factors are the highest rank, while financial strength is the lowest rank. Moreover, positive correlations of the techncial and managerial strength exhibit statistically significant with other factors.

Abstract

Spearman rho correlation and chi square cross tabulation techniques were employed to analyse secondary data with regards to a case study of direct cost for building constructions in 7 (seven) regencies/city in the Nanggroe Aceh Darussalam (NAD). The first technique was used to test statistically the rank differences of variables influencing direct costs among the seven regencies/city, while the second was employed to know the differences of frequencies of contractors’ perception regarding such direct cost from 7 (seven) regencies/city. The result shows that the ranks of direct cost variables from the highest to the lowest (i.e. material cost, transportation cost of materials, equipment rental cost, equipment operational cost, worker skills related costs, basic wages, wages related to location, wages related to work types) are significantly correlated between 7 (seven) regencies/city in NAD including significant correlation to the sum of 7 (seven) regencies/city. In spite of that, there are four variables influencing direct cost showing the differences of frequencies from 7 (seven) regencies/city in NAD, namely, transportation cost of materials, equipment rental cost, wages related to work types and wages related to location condition. While material cost, equipment operational cost, basic wages, worker skills related costs show no differences.
