The Impact

This paper presents the use of tools and approaches of system dynamics in the analysis of the efficiency of BIM tools implementation in relation to the management and planning of investments in the construction sector. The dynamic model based on the approach of system dynamics allows to simulate the impact rate (range) of BIM implementation in strategic investment decision-making in the construction sector. Based on the analysis, the key parameters critically affecting the large construction investment projects are determined. The proposed model is implemented as a submodel in the dynamic model designed for potential refinements in the strategic planning of the extent of investments into projects of civil infrastructure of the Czech Republic. The model allows to test different strategies in the virtual world before their implementation. The prediction of future developments based on the proposed model allows to streamline planning and decision-making processes.

Collusive bidding has been a deep-seated issue in the construction market for a long time. The strategies implemented by bid riggers are deliberate, interactive, and complex, suggesting that antitrust authorities have difficulty preventing collusive behaviors. Based on game payoff matrixes, this study proposes a system dynamics (SD) model to present the deterrence of punitive measures, namely the certainty of punishment (CoP) and the severity of punishment (SoP), on regular bidders’ to-collude decision-making. Data were collected from the Chinese construction industry to test the proposed SD model. While the model was supported, the results indicate that the CoP has a greater impact than the SoP on deterring regular bidders from making to-collude decisions. Furthermore, these two punitive measures cannot be replaced by each other, given the same deterrence effects. Thus, the study demonstrates the usefulness of deterrence theory to inhibit collusive bidding in the construction sector. It also sheds some light on the formulation of competition policy from the perspective of deterrence.

Agricultural land comprises an important share of the total terrestrial land. Therefore it plays a crucial role in the health of the so-called foundation of all types of ecosystem services – biodiversity. This research aims at providing a tool for evaluating the state of biodiversity in an agricultural landscape by using different agri-environmental indicators. A system dynamics model is built that encloses agricultural land use parameters, agricultural land use intensity, landscape fragmentation patterns, crop diversity and other aspects that have an important effect on biodiversity in agricultural landscapes. This research is an attempt to use information available for public to assess the degree to which agricultural landscape may benefit from landscape greening activities, changes in crop management activities etc. At the end of this research landscape biodiversity of an intensive farming region in Latvia (Bauska district) will be evaluated.

The traditional decision-making process in construction is still driven by factors such as cost and time, not adequately addressing indicators to control their environmental impacts. So, how to improve environmental communication to incorporate sustainable building practices. The incorporation of environmental indicators may enlarge the scope of construction management tools. In the case of cost databases, widely used in the construction sector, this action can contribute to the communication and dissemination of environmental practices. This paper mapped 24 indicators from construction cost databases to assess their ability to communicate and disseminate environmental information. The research comprised: (a) a review of the use of cost bases in the environmental study, (b) identification of the most cited bases in 27 Brazilian civil engineering courses, and (c) analysis of the selected databases through of the assessment matrix, it crosses cost data versus environmental information. CYPE, TCPO, and ORSE presented performance medium, and higher results than SINAPI, BDCCM, and BCCA. The tools presented low control over environmental information, such as water and energy consumption, machine circulation and pollution generation. However, it has been observed that when adding environmental indicators, these tools can contribute significantly to disseminate good practices in its wide user base.

The Relationship

A critical analysis of the existing approaches to monitoring the main parameters of the environmental safety of industrial production is presented, a number of shortcomings are revealed associated with the limited compliance methods for assessing the compliance of environmental indicators with current standards, or the degree of information transparency of companies; the lack of consideration of the impact of dividend and investment policies of companies on the environmental safety of industrial production; lack of comparability of environmental performance in public reports. The scientific novelty of the proposed monitoring lies in the use of a systematic approach to the formation of the main parameters of environmental safety and the expansion of monitoring directions by including trends in the relationship between economic and environmental indicators calculated from the data of public reports of companies. The study was carried out on the example of the metallurgical industry in Russia, which made it possible to assess the representativeness of environmental reports and trends in the environmental safety of the industry.

Abstract Background The European building and construction sector is extremely resource-intensive. This makes the renovation of existing buildings, including the adaptive reuse of cultural heritage buildings (ARCH), important for reducing the materials and energy intensity of the sector. Currently, Europe is embarking on a Circular Economy (CE) strategy that directly affects the environmental indicators for buildings and landscapes, including ARCH. However, there is a misalignment between macro-level European CE policy goals and micro-level renovation and management of existing buildings and ARCH. The analysis shows that macro European Union-level indicators are too narrowly defined to effectively guide the implementation of CE at the micro-project level for ARCH. Results This policy study develops a comprehensive ARCH Circular Environmental Impact Indicator Framework to close this gap by: (1) defining the research question; (2) identifying the causal network; and (3) selecting the best indicators. The study compares Circular Environmental Indicators for ARCH projects to current and developing European management schemes. Best practices in environmental impact assessment at the project level are highlighted for the building and construction sector in Europe. Conclusions The proposed new framework is a comprehensive and suitable list of explicitly circular environmental indicators for ARCH. The framework has immediate practical applications for practitioners and policymakers interested in the CE regime for buildings in Europe.
