At the present stage of the development of the construction industry, based on the principles of sustainable development, special attention should be paid to the formation of construction waste. Reserves for improving the level of efficiency of waste management can be found in the application of modern information technologies and their adaptation to resource-saving problems. The use of information systems is advisable at all stages of the life cycle of a building. Today, the technology of building information modeling (BIM) is actively developing, which can significantly reduce the amount of waste generation in construction. This is possible with its implementation at the design stage, in order to avoid irrational design decisions, collisions, etc. Information systems for data transmission allow rapid exchange of information between project participants, promptly warn about changes in space-planning decisions, materials, structures and equipment. At the stage of operation, in the presence of the information model of the building, it is possible to create a planning system for the organization of works of major overhaul or reconstruction. This article also proposes a description of the functions that an information system must have aimed at coordinating the management of construction waste in the region.

Purpose The purpose of this paper is to address two research questions: which are the key factors that stimulate entrepreneurs to invest in ecopreneurship, and how ecopreneurhsip contributes to environmental sustainability. Design/methodology/approach To answer these questions, a framework has been developed to identify the incentives that lead entrepreneurs to invest in firms in the ecopreneurship through institutional and resource-based thinking. Findings From a survey of 91 Greek firms from the green service sector, it is shown that some specific institutional and resource-based view factors play a critical role in green entrepreneurs’ decisions, as well as some certain environmental practices that are frequently used by entrepreneurs to address environmental issues. Research limitations/implications First, the answer of the second research question through data collected by a questionnaire survey may be faced with skepticism by some authors, as it could be seen that entrepreneurs and managers of firms could have overstated their company's environmental activities. Second, although the sample selection of 91 firms is a representative sample (response rate 12.35 percent) of the total population of Greek green firms (761) and equal to other relative studies, a higher number of firms and a wider variety of green entrepreneurship ventures is necessary in future research. Practical implications The findings are useful for scholars, practitioners and policy makers since it provide information regarding the behavior of green entrepreneurs. Originality/value The paper analyze the types of green entrepreneurs in relation to the different features and strategies which are emerged from two theories, such as institutional and resource-based theory.

The Malaysian construction industry although it plays a crucial function in stimulating the economy, is lagging behind other economic sectors. This is due to its unique characteristics such as fragmentation and slow technology adoption. These very characteristics make the industry susceptible to construction disputes. Construction disputes were found to incur high transaction costs (TCs), affect the parties involved, and subsequently increase overall project costs. Because TCs measure the costs that incur from transaction activities, they can be used to better understand the benefits within each transaction. Additionally, TCs are the best mechanism for analysing the ‘unseen’ costs of construction procurement. Previous studies on the traditional, design-and-build, and public private partnership (PPP) procurement methods have demonstrated TCs affect the organizational dynamics of construction and selection of procurement. The emerging Building Information Modeling (BIM) technology is said to be beneficial in addressing the problems associated with disputes and overall project costs. Consequently, many projects embark on BIM adoption in procurement. Hence, this preliminary study seeks to identify the TCs of BIM-adopted procurement by employing a structured literature review to determine the components and activities within the BIM procurement within the BIM implementation. The initial framework for the components of TCs of BIM procurement was drafted by referring to RIBA Plan of Work with BIM overlay. The components are categorised into pre-contract and post-contract components. These components can serve as the basis for developing a framework that can serve as a guideline for construction players involved in managing the TCs of BIM procurement.

Building Information Modeling (BIM) is considered among the most challenging developments in the Architectural, Engineering, and Construction (AEC) industries. BIM is a software based three-dimensional design process that helps the AEC staff obtain and manage the digitally represented building data to support engineering, construction, procurement, and installation activities. The diffusion of the BIM approach in the construction industry has gained acceleration in the last decade. With the advances in information technologies, existence of highly capable commercial software packages, and mandates dictated by the clients, many construction companies have started to employ BIM in their projects. This study aims to investigate the BIM transition process in the construction companies. An interview has been conducted with the executives of a Turkish construction company to analyze the BIM transition process, through three main phases: pre-transition period, transition period, and post-transition period. In the pretransition period, the motivations of the company to adopt the BIM approach are examined. In the transition period, the challenges encountered and preventive measures taken are indicated. In the post-transition period, the short- and long-term effects of adopting the BIM approach are discussed. The study is expected to guide the construction professionals that intend to implement BIM in their transition process.

Interdisciplinary cross-cultural and cross-organizational research offers great opportunities for innovative breakthroughs in the field of smart cities, yet it also presents organizational and knowledge development hurdles. Smart cities must be large towns able to sustain the needs of their citizens while promoting environmental sustainability. Smart cities foment the widespread use of novel information and communication technologies (ICTs); however, experimenting with these technologies in such a large geographical area is unfeasible. Consequently, smart campuses (SCs), which are universities where technological devices and applications create new experiences or services and facilitate operational efficiency, allow experimentation on a smaller scale, the concept of SCs as a testbed for a smart city is gaining momentum in the research community. Nevertheless, while universities acknowledge the academic role of a smart and sustainable approach to higher education, campus life and other student activities remain a mystery, which have never been universally solved. This paper proposes a SC concept to investigate the integration of building information modeling tools with Internet of Things- (IoT)-based wireless sensor networks in the fields of environmental monitoring and emotion detection to provide insights into the level of comfort. Additionally, it explores the ability of universities to contribute to local sustainability projects by sharing knowledge and experience across a multi-disciplinary team. Preliminary results highlight the significance of monitoring workspaces because productivity has been proven to be directly influenced by environment parameters. The comfort-monitoring infrastructure could also be reused to monitor physical parameters from educational premises to increase energy efficiency.
