Lean construction and waste concept are two issues that have a very important position today. Lean manufacturing is a Japanese business plan born in Toyota in terms of emergence. This philosophy is the philosophy of production, which in the most basic sense qualifies as a waste and tries to eliminate everything that does not add value to the product or service, as a result, aims to reduce costs and give the business a competitive advantage. The definition of lean production philosophy corresponding to the construction sector also has a definition that includes similar goals, such as the idea phase, the preparation phase, the application, the audit and control phase, where the entire process is maintained without waste, the goal is to increase quality, the labor force and employee are valuable, an efficient construction process is created. In order to measure the level of awareness in the construction audit companies, which are one of the main branches of the construction sector, and the level of awareness on this issue, a survey was conducted by meeting face-to-face with technical personnel residing in Adana province. The results of the surveys have been converted into data sets in the appropriate format in Microsoft Excel. With the prepared data set, the reliability level of the survey was measured in the SPSS program and the analysis of the data was carried out through the WEKA program. The study used Association rule inference, which is one of the data mining methods. As a result of the results obtained, it was observed that the technical staff of the building audit surveyed did not have sufficien awareness of the issues mentioned.
