A correlation analysis between the capability of construction firms and efficiency of construction company using DEA

A ranking of construction capability evaluation is the one of considering fact when a owner choose construction company. However, sometimes, companies faces financial problem even if they are in higher ranking of construction capability evaluation. This study is doing correlation analysis for their connection between management efficiency evaluation and a ranking of construction capability evaluation in top 100 companies of the ranking. Output factors have a minus in chosen input-output factors for evaluating management efficiency of construction companies. Moreover, this study uses DEA and BCC Models, because they have difference in a size. There are 23 efficient DMUs for efficiency evaluation and they are scattered over the field. However, size efficiency has directivity tendency. There are strong DRS disposition in high 50% companies, and IRS inclination in the others. Evaluating the effectiveness and value of construction skills ranked 1 to 10 units divided into sectors, our analysis of the results 1 to 10 belong to the one between companies, as well as the effective number of DMU average, highest, lowest at the differences between different sectors shows the superior efficiency compared to other sectors, but no direction could not be found. At the correlation analysis result, it is not very relevant the CRS and VRS efficiency between construction ability and efficiency rank. However, scale efficiency has gotten a strong relevance
