    Abstract: Leadership in Environmental and Energy Design, LEED, is one of the most recognized green building certification systems in the world. Turkey is also one of the countries, where it is widely used. It offers different rating groups to address varying requirements of building and project types. LEED-v3 NC, the rating group for new construction, includes seven categories of credits: sustainable sites, water efficiency, energy and atmosphere, materials and resources, indoor air quality, innovation, and regional priority. The maximum achievable point is 110. Local conditions significantly affect the achievement of some of the credits, as LEED is originated in the USA. This study focuses on the assessment of 122 LEED-v3 NC certified buildings in Turkey, considering the points achieved in each category. The aim is to understand which categories are successfully fulfilled and more challenging for implementation. Analysis results show that buildings receive higher points from water efficiency, sustainable sites, innovation and regional priorities, when compared to indoor environmental quality, energy and atmosphere and material and resources categories in Turkey. The lowest category is identified as material and resources. This situation should lead the new projects taking precautions to this individual area especially at the beginning of “planning step” in construction process. Recognizing the successful implementations for earning points and the challenging issues in Turkish construction industry regarding green buildings can be of benefit for professionals in this area.

    Abstract: Damage Mechanics has become a useful theory in describing the nonlinear behavior of solids driven by the nucleation and growth of cracks and microcracks. This approach, based on the first principles of mechanics and thermodynamics, has also been combined with classical theories of plasticity to address a wide range of loading applications. In spite of the many different damage mechanics models and representations that are proposed, the foundation of damage mechanics is not well understood or at least not thoroughly published giving rise to the many inaccurate definitions and formulations. The intent of this paper is to provide the background of the continuum damage mechanics outlining the fundamentals on which this field theory is set up. The internal variable theory of continuum thermodynamics is reviewed and is shown that with Legendre transformation technique, various potential functions can be developed for damage mechanics formulation in either stress or strain space. The concept of constrained or neighboring equilibrium state is also introduced and is explained. The paper will conclude with the derivation of the general damage potential and a suggestion is given for the isotropic damage formulation with the resulting uniaxial stress-strain relation.

    Abstract: Design of green buildings involves specific processes compared to conventional construction projects that require participation of several disciplines. Having particular activities, functions, and physical aspects, green buildings impose their own difficulties during design. Building Information Modelling systems (BIM) use different software for virtual simulation of characteristics of projects, which promotes early detection of potential problems even before production of the intended design details. Implementing BIM technology in design stage, not only helps to minimize design problems, but also to shorten the stage itself. With this effect of BIM combined with sustainable practices and energy efficient technologies, design stage alone can be considered as a sustainable application of construction activities. Therefore, principles and requirements of green building certification systems can easily be performed for projects with capabilities of BIM technologies and tools. In this study, redesign of Yildiz Technical University, Faculty of Civil Engineering Building based on LEED certification system using BIM tools is presented. The project is prepared as part of a capstone project by senior civil engineering students. Design stages are planned to promote sustainability and qualify the requirements of LEED v3 BD+C (Schools). The main objective is to introduce the students to two major trends in construction industry (green buildings and BIM applications) and to create awareness of sustainable construction, green building certification systems and emerging technologies.

    Abstract: Decisions taken in the process of organizing and managing construction structures pose various risks and can adversely affect people's lives. Geotechnical risks constitute a large part of the risks of construction projects. Technical problems related to soil characteristics can lead to delays in the schedule and cost overruns in the budget of the projects. Geotechnical risks with the potential to cause major damage to projects must ultimately be prevented before they happen. Recently, many technological tools are available to use strategically for the management of such risks. The integration of various numerical methods with different technological tools might be effective for this purpose. The use of the right method or tool will greatly contribute to geotechnical risk management. Since the management of these risks can directly and/or indirectly affect the work program, the healthy progress of the project depends on the adoption of correct risk management approaches and strategies. With the aim of o determine the effect of technological tools in the management of geotechnical risks in this study, literature review about the management of geotechnical risks in construction projects was examined, and the methods used were compiled. The results of this study are expected to be a guide in terms of introducing technological tools to practitioners in the sector and improving risk management in their course.

    Abstract: Meeting the quality requirements in construction works is critical for structural safety of the buildings, particularly in seismically active regions with old building stocks. Code compliance through strict inspections is essential not only for reliable structures, but also for prevention of cost and time overruns causing financial losses. In Turkey, building inspections are mandatory during the construction phase of the projects and building inspectors are responsible from the inspection of the construction works to ensure code compliance. Building inspectors are frequently subjected to different type of problems due several defects during inspections. This study aims to identify the frequently encountered defective construction works based on a quantitative study. A questionnaire was administered to 57 building inspectors by using 1-5 Likert scale to evaluate 20 critical construction work items. The results, which were ranked according to the Relative Importance Index (RII) showed that concrete works, reinforcement works, and HVAC are the top three works where problems were frequently observed during inspections. On the other hand, less problems were observed in painting, landscaping works and prefabricated construction works.

    Abstract: A competent contractor can be regarded as a catalyst to deliver a truly sustainable building and thus help to mitigate detrimental impacts to the built environment. The prequalification phase provides confidence to the owner to achieve a project’s sustainability requirements and reinforcing a mutual relationship with the selected contractor. This study proposes a decision framework for green building (GB) prequalification, which aims to improve the owner/contractor relationship. A comprehensive literature review was conducted to identify prequalification factors. To draw attention to GB projects and trust-based prequalification factors, a focus group discussion was performed with GB experts. A decision framework consisting of 12 relationship-based factors was then subjected to a fuzzy decision-making trial and evaluation laboratory (F-DEMATEL) method. The followed methodology aided the determination of the relationship-based prequalification factors, specification of the importance of factor degrees, illustration of the interrelationship among factors and consequently reveal the most causal factors that might contribute significantly to the improvement of the owner and contractor (O & C) relationship in GB projects. Results pointed out the importance of financial factors, while the same factors were found to be the driving force behind the improved relationship between O & C. Pertinent literature on prequalification in GB projects are limited, and no prior indepth study has investigated the prequalification phase based on trust and the mutual relationship between O & C. Highlighting the gap in the literature about trust-based contractor selection models, the proposed study can be useful to minimize conflicts and claims between the O & C, which could positively influence direct owners to consider GB projects.
