Article Citation - WoS: 87Citation - Scopus: 100Determining Attribute Weights in a Cbr Model for Early Cost Prediction of Structural Systems(American Society of Civil Engineers (ASCE), 2006) Doğan, Sevgi Zeynep; Arditi, David; Günaydın, Hüsnü MuratThis paper compares the performance of three optimization techniques, namely feature counting, gradient descent, and genetic algorithms (GA) in generating attribute weights that were used in a spreadsheet-based case based reasoning (CBR) prediction model. The generation of the attribute weights by using the three optimization techniques and the development of the procedure used in the CBR model are described in this paper in detail. The model was tested by using data pertaining to the early design parameters and unit cost of the structural system of 29 residential building projects. The results indicated that GA-augmented CBR performed better than CBR used in association with the other two optimization techniques. The study is of benefit primarily to researchers as it compares the impact attribute weights generated by three different optimization techniques on the performance of a CBR prediction tool.Conference Object Citation - Scopus: 2Bim Execution Process of Construction Companies for Building Projects(ISEC Press, 2017) Gercek, B.; Tokdemir, O.B.; Ilal, M.E.; GunaydinBuilding Information Modeling (BIM) has been an emerging concept in architecture, engineering and construction (AEC) industry with a vast amount of promising benefits to construction projects. Implementation of BIM, however, requires comprehensive research and strategic planning. Industry-wide and organizational implementation guidelines and standards have been published around the world either to encourage organizations to adopt BIM or to present the minimum requirements to be followed where BIM implementation is a statutory obligation. In contrast, governments or organizations in several countries such as Turkey have not mandated BIM implementation and provide no guidance. Organizations in these countries which plan to adopt BIM processes are forced to develop their own implementation plans. The purpose of this study is to provide guidance in BIM implementation for construction companies in countries where BIM implementation has not been mandated particularly during the construction phase of the building projects. 23 BIM standards and guidelines covering the BIM execution process have been reviewed. Topics that need to be addressed by BIM implementation plans have been identified and categorized under four headings. A case study of BIM implementation at a large construction company that focuses on conducting quantity takeoff and cost estimation is presented, and unique challenges of BIM implementation in Turkish AEC industry are discussed. © 2017 ISEC Press.Doctoral Thesis Using Machine Learning Techniques for Early Cost Prediction of Structural Systems of Buildings(Izmir Institute of Technology, 2005) Doğan, Sevgi Zeynep; Doğan, Sevgi Zeynep; Günaydın, Hüsnü Murat; Günaydın, Hüsnü MuratIt is desirable to predict construction costs in the early design stages in order tomake sure that target costs are met and competitive prices are realized. This study investigates the possibility of predicting the cost of construction early in the design phase by using machine learning (ML) techniques. To achieve this objective, artificialneural network (ANN) and case based reasoning (CBR) prediction models were developed in a spreadsheet-based format. An investigation of the impacts of weight generation methods on the ANN and CBR models was conducted. The performance of the ANN model was enhanced by experimenting with the weight generation methods of simplex optimization, back propagation training, and genetic algorithms while the CBR model was augmented by feature counting, gradient descent, genetic algorithms (GA), decision tree methods of binary-dtree, info-top and info-dtree.Cost data belonging to the superstructure of low-rise residential buildings were used to test these models. It was found that both approaches were capable of providing high prediction accuracy, 96% for ANN using simplex optimization for weight determination, and 84% for CBR using GA for attribute weight selection. A comparison of the Excel-based ANN and CBR models was made in terms of prediction accuracy, preprocessing effort, explanatory value, improvement potentials and ease of use. The study demonstrated the practicality of using spreadsheets in developing ANN and CBR models for use in construction management as well as the potential benefits of enhancing ANN and CBR models by using different weight generation methods.Master Thesis Passive Solar Desing Strategies for Buildings: a Case Study on Improvement of an Existing Residential Building's Thermal Performance by Passive Solar Design Tools(Izmir Institute of Technology, 2003) Bilgiç, Serkan; Günaydın, Hüsnü MuratThis thesis investigates the potentials of the use of Passive Solar Design strategies in existing low-rise residential buildings in the context of energy-efficient building design. Among the ways of developing energy-efficient building design, there are mainly active and passive systems to consider and the thesis focuses on passive ones which require integration of architectural characteristics and energy-efficiency strategies, which can likely be cost-effective and thermally comfortable as a result of that integration.In order to achieve the objective of the study, a methodology has been developed. Fist a thorough literature survey is conducted. Then examples related to subject are investigated. Finally an existing residential building is selected and analysed as the case study. Current thermal performance and improved thermal performance of this building are analysed by the help of a software called Energy-10. Results of both original and improved projects are interpreted accordingly.In buildings, Passive Solar Design strategies can provide fundamental comfort conditions related to heating, cooling for thermal and natural lighting for visual comfort or help building.s conventional mechanical systems achieve these conditions requiring less amount of energy. Some of the Passive Solar Desgin strategies are seem in traditional architecture from harsh cold to hot humid climate, they have been in harmony with their environment and provide comfort conditions adjusting the outdoor climatic features by climatic design strategies and they are called as climate-responsive buildings. Solar orientation, solar apertures, thermal mass, solar chimneys, wind captures, lattice brise-soleils or mushrabiyas are the Passive Solar Design elements which have been used in traditional buildings, now abandoned, running by means of natural air currents.To achieve a low-energy building, thermal insulation ought to be considered as the main energy-efficiency feature. Turkish thermal insulation standarts .TS 825. is deficient for designing low-energy buildings and there is no regulations that make the designers feel the desire to utilize low-energy concepts for their designs. Besides, the building.s morphological organisation should be involved with respect to climatic and environmental data. One of the most important criterion in designing an energy-efficient building is incoprating properties of microclimate of the site that the building is to be placed. Using environmental (climatic, geographic, etc.) data well in building designs can lead to energy efficiency. Solar geometry, latitude, altitude, wind patterns, vegetation, hills and neighbor buildings are the determinants of microclimate of a site.The findings of the study indicate that with the energy-efficiency design strategies by passive solar components having the additional cost of about 9% of the total building cost, it is possible to save the total annual energy used in this specific residential building by 18%. There are three types of energy need for the space conditioning and visual comfort (i. e., heating, cooling and lighting), the maximum energy saving is achieved in heating energy use by 61% decrease, lighting energy use is also decreased by 40%. However, in cooling energy need, there is an increase of 34%. This amount is overshadowed by passive solar gains in other energy savings (i. e., heating and lighting) and when the cooling strategies of the building (i. e., natural ventilation and stack effect ventilation) are considered, the building might be said to perform well in terms of thermaly in annual operation.Master Thesis Political Tactics in Building Construction Industry From the Architects' Perspectives(Izmir Institute of Technology, 2009) Ülkeryıldız, R. Evren; Günaydın, Hüsnü Murat; Günaydın, Hüsnü MuratPolitical behavior in organizations has been the subject of numerous studies. The emergent picture from these studies is that political behavior in organizations is an inevitable part of any human-based activity. Architectural design practice is one of those human-based activities. Political behaviors are inevitable reality of any human based activity. Political behavior can have functional or dysfunctional consequences. The key challenge facing architects is managing political behavior in order to reduce or eliminate dysfunctional consequences of political behavior. Managing political behavior starts with understanding and identifying political tactics used by social actors involved in architectural design practice. The research presented in this thesis builds on this premise. It empirically explores (1) the use of political tactics by primary social actors of any construction project (i.e., clients, main-contractors and subcontractors) (2) communication channel used in send politically motivated messages by social actors and (3) frequency of political tactics used throughout different stages of a construction project. The research findings reveal that political tactics are commonly used in architectural design practice and political tactics are most frequently used by social actors in the construction process. Furthermore, research findings suggest that social actors use oral communication channels rather than written communication channels for sending politically motivated messages, and the main-contractors heavily use political behavior in the architectural design practice. Key words: organizational politics, political tactics, political behavior, architectural design and construction practice in Turkey.Master Thesis The Evolution and Change of Building Facades: a Research for Developing Alternative Composite Surface Materials(İzmir Institute of Technology, 2007) Çıkış, Dilaver Turgut; Günaydin, Hüsnü MuratCladding of buildings is an important and commonly applied activity area of building sector. As it is known major purpose of cladding is to separate the indoor environment from the outdoors in such a way that indoor environment conditions can be maintained at level suitable for the buildings intended use. Therefore from the functional point of view it can be defined as, the part of the building that is non load bearing exterior wall that must defend the interior spaces against invasion by water, wind, sun, light, heat and cold, and all the other forces of nature. Besides this it must also fulfill the aesthetic, economic and security consideration. The design of the building façade has become much more complicated with development of new methods of construction, the requirements for a highly controlled interior environments, stress on energy efficiency, advent of materials and new production methods. But it seems that available technologies on ordinary building sector relay on the analog production methods. Analog production process depends on technical drawings and the interpretation of drawings. The human interpretation is the basics of the systems. On the other hand, new design tools that introduced by computer aided design programs proposes new conceptions of space that beyond the limits of Cartesian understanding of form and construction. It is known that computer aided design and production methods are applied pervasively in numerous different sectors. Articulation of computer aided design and manufacturing processes with digitally driven assemblage methods is an important task that is expected to be solved by the building sector. Building envelope systems as being one of the most important building component from the points of both identity and utility of buildings, is has to be reconsidered as a part of the adaptation of whole construction sector. It is also a measure of responsibility on the part of architects. Besides material design, production processes, and connection details of the components with the other parts of the building are the other important dimensions of the envelope systems.Conference Object Citation - Scopus: 3Izmir Municipality Housing and Zoning Code Analysis and Representation for Compliance Checking(Universiteit Twente, 2013) Macit, Sibel; İlal, Mustafa Emre; Günaydın, Hüsnü Murat; Suter, GeorgSystems for code compliance checking of building projects require representation of building codes. Building codes are complex, and the development of computer implementable representations is challenging. As a case in point, this paper reports on experiences gained while modeling ̄zmir Municipality Housing and Zoning Code (IMHZcode). First, IMHZcode was analysed to understand the various types of information contained in it in order to develop a comprehensive building code model. The rules were classified according to their formalizability and self-containedness. Then, existing modeling approaches were evaluated to find the most convenient method that meets the needs for modeling IMHZcode. A key criterion used in this evaluation was ease of maintenance by non-programmers. The paper concludes with an illustrative example of the selected methodology's application within the context of IMHZcode.Book Part Factors Affecting the Learning Process of Professionals in Architectural Design Firms(CRC Press, 2009) Ozturk-Barlak,G.B.; Arditi,D.; Gunaydin,H.M.; Kale,S.; Yitmen,I.Learning is considered to be a sophisticated process and a source of competitiveꀊadvantage. Learning is essential in project-based environments. The one-of-a-kind structure of the operations of architectural design firms triggers special learning needs and requires a continuous learning activity. Learning is considered to improve an architectural design firm’s efficiency by recognizing the role of individuals in enhancing the firm’s objectives. However, theoretical research on individual professionals’ learning process in the architectural design is rather uncommon. The process of individual learning is composed of (1) data acquisition (2) assessment of the acquired information and (3) implementation of the knowledge gained in a group setting. Ten factors were identified to assess the effectiveness of the learning processes of professionals. This study is the first study in the field of architecture that presents a conceptual model about the factors that affect the effectiveness of the learning process of professionals. © 2010 Taylor and Francis Group, London, UK.Doctoral Thesis Computer Representation of Building Codes for Automated Compliance Checking(Izmir Institute of Technology, 2014) Macit, Sibel; Günaydın, Hüsnü MuratThis dissertation constitutes a study in the field of automated compliance checking, with a concentration on building code representations. Development of compliance checking systems has been an area of research that aims to provide computational support for accurate compliance checking of building projects against applicable building codes in a time and cost effective way. Systems for compliance checking of building projects require appropriate representations for building codes. Building codes are complex documents written in natural languages, and the development of computable representations is challenging. This dissertation proposes and demonstrates a new representation model and an accompanying modeling methodology for representing building codes in computable form that can be utilized in the development of automated compliance checking systems. The model adopts the four level representation paradigm as a theoretical base and uses the semantic modeling approach for developing the building code representation. The model breaks down the representation into four levels which allows separate modeling of domain concepts, individual rule statements, relationships between rules, and the organization of the building code. The dissertation shows that decomposing a building code into four levels and modeling rules based on the semantic-oriented paradigm is an effective modeling strategy for representing building codes in a computable form that is independent of automated compliance checking systems. The applicability of the model has been evaluated through a case study. The case study successfully illustrates the modeling of building codes that constitute parts of İzmir Municipality Housing and Zoning Code, as well as a prototype implementation of an automated checking system utilizing this building code representation.Doctoral Thesis A Model for Assesing Project Management Maturity Level of Architectural Design Offices (arch-Pmm)(Izmir Institute of Technology, 2007) Beset, Doğan Arda; Günaydın, Hüsnü MuratThe aim of this dissertation is to develop a model to assess .The Project Management Maturity Level of an Architectural Design Office. (Arch-PMM). The purpose of ARCH-PMM is to develop an environment for productive and efficient design conditions. By increasing the levels of ARCH-PMM, architectural design office will create opportunity to focus on its concerns for high quality architectural design process. To determine whether Arch-PMM assessment methodology is working properly, a semi structured survey is conducted with selected architectural design offices. This study is the first attempt that focuses on architectural design offices. PM practices and processes. A 5 leveled PM Maturity Model is developed to assess architectural design offices. current PM Maturity level. Maturity levels are assessed vis a semi-structured survey. 71 Members of the Association of Turkish Independent Architects (ATIA)participated to semi-structured survey to validate the model. A list of demographical questions was asked to draw the demographical picture of the architectural design offices. Both, maturity levels and demographical data are analyzed. The results of the assessment provide the necessary information for the architects to improve their PM processes and activities. Project Integration Management was highly mature among the other function areas and it.s followed by Project Scope Management. The least matured function area was the Project Risk Management. High correlation values between the number of staff and all PM function areas are also observed. Yearly income level and overall maturity level of the architectural design offices are found to be related at correlation high levels (r.0.73). The well defined structure of architectural design process seems to support project management culture and have potentials of high project management maturity levels.
