Inefficiency stands as a major problem in construction industry. Lean thinking is a relatively new process improvement philosophy which approaches inefficiency by reducing the waste. Although the inefficiency of design stages has been associated with the poor results of construction projects, less attention has been paid on the relationship between lean thinking and architectural design process. While there is a strong potential for improvement in the design processes via application of lean thinking, an analysis of waste items has never been done. Thus, this study aims to identify, categorize, and rank the waste items in architectural design sector. In the first stage of the study 28 design waste items were identified and classified under 8 lean production waste categories as a result of semi-structured interviews conducted with senior architects performing in Ankara, Turkey. In the second stage, a questionnaire was executed over a larger population of architects to examine the "frequency of occurrence", "impact over cost", "impact over duration", and "impact over quality" for each design waste item. The findings were statistically analysed and an evaluation of risk was completed. The statistical analysis of the questionnaires shows that there is a shared understanding of impacts of waste items over architectural design processes, with strong statistical evidence over their validity. The results of the study can be utilized for the strategical implementation of lean production philosophy in architectural design process.

Lean design management – an evaluation of waste items for architectural design process Mazlum, Salih Kaan; Pekeriçli, Mehmet Koray; Department of Building Science in Architecture (2015) Waste is standing as a major problem in the body of construction industry. Lean thinking in construction accepts any inefficiency as waste which results with more usage of equipment, materials, labor, time or capital in larger quantities than those considered as necessary. Although inefficiency of design stages has been identified as a major factor that reduces the efficiency of construction projects, less attention has been paid on the relationship between lean thinking and architectural design process. Th...
Lean Project Management using Unmanned Aerial Vehicles Ersöz, Ahmet Bahaddin; Pekcan, Onur; Tokdemir, Onur Behzat (2019-02-01) As the construction industry is one of the dominant contributors to the world’s total CO2 emissions and it has huge negative impacts on the environment, sustainable construction has become a key aspiration in the field. Through utilizing eco-friendly design and resource efficiency, sustainable construction is considered as the main concept to create and operate a healthy built environment. Although sustainability has been demonstrated as a timeless objective for continuous development in Turkey’s government...
An investigation into the implementation of construction automation and robotics technologies for construction waste management Kılıçkan Öztürk, Sabire Melek; Elias Özkan, Soofia Tahira; Department of Architecture (2022-8) The construction industry is responsible for tons of construction waste. It is crucial to take the necessary precautions to avoid the impacts of construction waste on the environment. With the help of developments in automation technology and building information modeling systems, robotics in the construction industry is getting more common every day. It is argued that construction robots can be effective in the management of construction waste. This study aims first to understand the reasons for construct...
Project-based innovation performance assessment in the housing sector: a case study using innovation radar Bilgin, Pınar; Dikmen Toker, İrem; Department of Civil Engineering (2019) Unique and complex nature of the construction industry brings a high number of injuries in construction sites. Although the importance given to the health and safety practices increased recently, still there exists inadequacy of preventative practices along with poor risk management policies. One of the reasons that cause a high incidence of injuries is inability to identify scenarios that create injuries effectively, which in turn makes finding optimal risk mitigation strategies difficult. So, the objectiv...
Safety risk assessment for tunnel construction: application of AHP to Marmaray project Pehlivanlı, Umuthan; Dikmen Toker, İrem; Department of Occupational Health and Safety (2019) Apparently, construction industry has one of the highest work accident rates in the World. While construction industry has many sub branches, each and every one of themhasitsowndistinctives. Thesevarietyofprojectsbringspecialtypesofhazards and hazard sources together. Tunnel construction is a very speciﬁc area to work on and creating a safe working environment especially for the underground projects is a challenging task. While conﬁned space works carry different kind of risks, management should be more att...
