The objective of this thesis is to reveal the perception of the Turkish contractors toward ISO 9001 Quality, ISO 14001 Environmental and OHSAS 18001 Occupational Health and Safety Management Systems using questionnaires. All of the companies participating in the survey have already been ISO 9000 certified. Thus, the questionnaire prepared included more details for the Quality Management System. The results of the questionnaire outcomes are statistically analysed. Analysis of the survey results show that the most common motivators of Management Systems for Turkish contractors are to qualify to tender for local and international projects and to increase competitiveness in overseas markets, however the vision approach of top management is not less important than the financial issues. Most of the companies stated that they implement Management Systems as a part of their improvement strategy as well. This proves that the companies are aware of the benefits of certification in the long term period. Although the most expected advantages of the systems are qualification to tender for projects both locally and internationally, as well as gaining competitive advantage, it has been observed that other benefits are realizedby the Turkish contractors such as; more systematic record keeping, higher company prestige, increased client satisfaction. The major disadvantages realized by practicing the Management Systems are increased documentation and workload. The solution is proposed as to set an internal network and to integrate the systems to reduce paperwork. In conclusion, all of the Management Systems were believed to be as useful tools and Turkish contractors think that their advantages overcome disadvantages.
