The aim of this study was to determine the quantity of construction waste for several construction materials and to state the probable origins of this waste, depending on case studies in Turkey. There is a lack of documented quantitative data in Turkey on how much material waste the construction industry generates and what amount of such materials remain unused due to this waste. Although some amount of waste is accepted as unavoidable, the probable reasons for it are unclear. Therefore, the study focused on determining waste percentage values for certain materials based on several construction projects and assessing the reasons for this as stated by the professionals who were involved in the construction process of these projects. For practical reasons, it was confined to the material amounts in the bill of quantities, progress payment reports and invoices for four different construction materials; namely, ready-mixed concrete, rebar, brick and floor block, which belonged to eight different projects of two construction companies. Data compiled on these aspects were analyzed statistically via ANOVA and regression analyses. The results showed that waste percentage values displayed differences among materials. Design-related aspects, skill level and attitude of labor, incorrect calculation of material quantities, contractual clauses and material defects were the most effective reasons for waste within the projects analyzed.

The effects of Turkish disaster regulations on architectural design
Özyıldıran, Güler; İmamoğlu, Vacit; Department of Architecture (2007)
The aim of this study is to examine the role of ‘Turkish Disaster Regulations’ on architectural design. Although the preliminary aim of Turkish disaster regulations is to provide knowledge for designers and builders to control structural and constructional system of buildings that can resist disasters in the pre-disaster period, these regulations can create some restrictions for architects in their design process. Following an analytical examinations of Turkish disaster regulations that have been developed ...
Comparative study of the structure of traditional timber housing in Turkey and Japan
Matsushıta, Satsukı; Balamir, Aydan; Department of Architecture (2004)
The objective of this thesis was to examine the structural order of traditional timber houses in Turkey and Japan. A comparative analysis, based on literature and a case study was made toestablish differences of traditional timber structures in the two countries by examining their spatial organization, spans and pitches of the timber components. Four Houses were chosen for survey from Safranbolu, Turkey and Gokayama, Japan. Following two points were appeared as a conclusion: in Turkey, the structural order ...
Assessing thermal comfort conditions: a case Study on the METU Faculty of Architecture building; the case of ODTÜKENT
Çakır, Çağrı; Elias Özkan, Soofia Tahira; Department of Building Science in Architecture (2006)
The aim of this study was to evaluate the effects of environmental design parameters on thermal comfort conditions in the METU Faculty of Architecture Building located in Ankara. The building had some problems in terms of indoor climatic conditions, both in winter and in summer. It was evident that some design parameters caused this undesirable situation. The study therefore focused on understanding and evaluating the effects of design-dependent elements such as thermal mass, the size and orientation of win...
Bio-climatic architecture in libya: case studies from three climatic regions
Elwefati, Nahla Adel; Elias Özkan, Soofia Tahira; Department of Architecture (2007)
The aim of this study was to investigate the bio-climatic characteristics of traditional and contemporary residential architecture in three different climatic/geographical regions of Libya, which are represented by Tripoli in the “coastal region”; Gharyan in the “mountainous region”; and Ghadames in the “desert region”. It was undertaken to understand and evaluate the effects of building layout and orientation, wall thicknesses, ceiling height, construction materials, thermal mass and size of windows, on th...
Historical background of Libyan mosque architecture: assesment and criticism of mosquesin Ajdabiya city
Buhlfaia, Saeid; Cengizkan, Ali; Department of Architecture (2006)
The study attempts to trace the development of mosque architecture in Islamic history, in modern architecture in the world, specifically focusing on the history of the mosque in Libya. It investigates whether the conformity of mosque components and finishing is due to historic, current and local Islamic prescriptions; due to functional purposes and necessities, or merely as an imitation of the stereotype styles for loyalty to mental and habitual traditions regardless of functions. The main objective of this...
