In order to formulate effective waste reduction strategies in construction projects, it is essential to continuously monitor and analyze the waste generation and improve the existing processes continuously. This requires to establish a waste benchmark, based on the previous experiences in the organization, to assist the project team in taking efficient and timely actions to prevent the waste at source, and enhance the corporate waste management capability. The current study is carried out to explore the waste management in prefabricated steel structure construction companies in Turkey and develop a process model using an integrated waste management tool, to facilitate and improve the efficiency of existing waste management procedures. A classified set of materials and potential waste causes were listed through detailed literature review, studying real project records and interviewing with experts in the sector. A questionnaire survey has been carried out in collaboration with the Turkish prefabricated steel structure building companies to investigate the current performance of companies in material waste management and identify the most waste-prone materials and the main causes of waste generation. Also, the existing deficiencies in waste management processes were explored and factors plugging the way of effective waste management were identified. An integrated waste management process model and a supporting application were developed for the Turkish prefabricated building companies, in order to facilitate waste estimation, management, monitoring and controlling. Finally, the developed tool, the “Waste Tracker”, was tested and verified by the sector professionals. The testing and verification process gave favorable results. Although the findings on waste-prone materials and waste management practices reflect the situation in the Turkish prefabricated construction industry, it is believed that the proposed process model as well as the tool are generic and be modified to other countries and industries after some modifications.

Identifying the barriers of implementing lean construction principals in developing countries Markazi Movaghar, Ehsan; Elias Özkan, Soofia Tahira; Department of Building Science in Architecture (2016) The construction industry is congested with many types of project management systems to control and manage construction projects but none of them really look in-depth to maximize the efficiency of the work flow and minimizing waste. The implementation of the lean construction principles into the local construction scene can improve the problems. However, lean construction is complex and can be risky if not properly managed. Lean construction efforts in some other countries have not been successful due to th...
Development of a knowledge-based tool for waste management of prefabricated steel structure projects Mirshekarlou, Babak Rahmani; BUDAYAN, Cenk; Dikmen Toker, İrem; Birgönül, Mustafa Talat (2021-11-01) Although the construction industry is critical for sustainability goals due to the high amount of waste it generates, its waste management performance is still not at the desired level. One of the main reasons for this can be attributed to the lack of enough knowledge of construction companies on the sources/reasons of waste and amount of waste. The major aim of this study was to develop a knowledge-based tool for capturing, storing, and disseminating waste-related knowledge for prefabricated steel construc...
Development of a knowledge-based risk mapping tool for International Construction Projects Yıldız, Açelya Ecem; Dikmen Toker, İrem; Birgönül, Mustafa Talat; Department of Civil Engineering (2012) Due to its high-risk nature, international construction projects are more vulnerable to adverse changes in project environment and company objectives. To achieve successful project outcomes, early provision of risks has a vital place in managing construction projects. Within the literature, several risk assessment methodologies have been offered to simulate probable consequences of risks. The majority of the proposed methodologies are limited in reflection of real project conditions as they require probabil...
A Multi agent risk analysis and sharing platform for international construction projects Dağkıran, Gülşah; Dikmen Toker, İrem; Tanyer, Ali Murat; Department of Civil Engineering (2015) The risks and complexities that are naturally inherent with construction projects and the diverging interests of the parties involved, cause deviations from the project objectives and make claims an unavoidable consequence in construction projects. Risk management is accepted as one of the critical success factors to handle the claim management process effectively. In construction management literature, while there are several studies to develop a mechanism for risk management, decision making and dispute r...
Development of an IT-based tool for portfolio assessment and management for construction companies Bilgin, Gözde; Dikmen Toker, İrem; Özorhon Orakçal, Beliz; Department of Civil Engineering (2019) Development in the construction industry has leaded most of the construction companies to undertake more complex projects than before, which are generally executed concurrently. Therefore, project management routines of the companies may not support effective management of multi-projects. Project portfolio management approach has been suggested to meet requirements for coordinating multi-projects to meet strategic objectives under limited resources. Since project portfolio management requires a comprehensiv...
