Comprehensive Examination

Dust pollution is a key issue that contractors ought to address in the sphere of sustainable construction. Governments on behalf of the public assume part of the responsibilities for minimizing dust emissions on construction sites. However, the measures that are useful for governments to fulfill such a responsibility have not been explored explicitly in previous studies. The aim of this research is to map out China’s practices in this area with the intention of filling the knowledge gap. Using a combination of research methods, five categories of governmental measures are proposed: technological, economic, supervisory, organizational, and assessment-based. Data from 37 major cities in China are collected for analysis. While the proposed categories of measures are demonstrated in China, the data analysis results show that governments prefer technological and organizational measures, and institutional guarantees and technological innovation are a prerequisite for dust-free construction. This research provides a comprehensive examination of construction dust control from the perspective of governments, and it can assist governments in improving the performance of dust management in the construction context.

This study aims to quantify the losses to third-parties on construction sites by determining the loss indicators and identifying the relationship between the losses and the indicators to improve the sustainability on building construction sites. The growing size and intricacy of recent construction projects have resulted in the growth of losses, both in quantity and frequency. Notably, third-party losses are rapidly increasing owing to the urbanization of the environment and increases in construction scale. Therefore, for efficient and sustainable construction management, a financial loss assessment model is essential to mitigate and manage such loss. This study uses the third-party losses on construction sites obtained from a major South Korean insurance company to describe the difference from the material losses and to disclose the loss indicators based on actual economic losses. ANOVA analysis and multiple regression analysis are adopted to identify the variance and define the loss indicators and to make prediction models, respectively. Several groups of loss indicators are investigated, including construction information and the occurrence of natural disasters. The findings and results of this research afford an essential guide to sustainable construction management, and they can serve as a first stage loss assessment model for construction projects.

Dust Generation

Construction sites constitute major sources of pollutants creating negative impacts on the environment. Sustainable construction aims at mitigating these negative externalities while promoting economic and social outcomes. Dust pollution in construction sites is an invisible hazard, which is often ignored as little more than a nuisance. Although behavioral control is a popular way of preventing dust generation, past research has paid little attention to worker behavior regarding dust mitigation. This study aims to test a model that predicts intentions to alter the conduct of workers towards dust control in construction activities. This study adopted a questionnaire survey design with construction participants in Sri Lanka, using structural equation modelling to test several hypotheses based on the Norm Activation Model. The results proved that awareness of consequences and ascription of responsibility could have a positive impact on personal norms, which in turn could influence the behavior of site employees. The study also provided new insights on employees’ awareness of dust hazards, their sense of responsibility for its control, and the importance of their company. Policymakers and practitioners are recommended to pay more attention to how to harness worker’s support to mitigate dust pollution, and construction companies should initiate educational campaigns to raise awareness about environmental impacts, to influence personal norms of the workers in building sites. This research contributes to the body of knowledge by enhancing our understanding of factors influencing employees’ dust control behavior.

The civil construction industry is one of the sectors that most consume natural resources in the world and, consequently, one of that generate more waste. Thinking about constructive techniques that generate less impact on the environment is vital to ensure sustainable development. In this scenario, the Life Cycle Assessment (LCA) has been presented as an internationally recognized approach, that assesses the potential impact of products and services on human health and the environment, throughout its entire life cycle. Aimed to identify construction techniques and vertical closing systems that generate less impact and consumption of natural resources, the impacts generated by the life cycle of the three vertical closing systems most applied in construction sites in Brazil were compared: ceramic brick masonry system (CBr); concrete block masonry system (CBk); and structural blocks masonry system (SBk). The SBk proved to be the least impacting to the “Resource Scarcity”, “Damage to Human Health”, and “Damage to the diversity of Ecosystems” interesting areas. This performance is directly related to the use of cement CPIII type and also by the fact that the SBk consumes less concrete and mortar than the others. Already the "Water Consumption" area, the CBk was the least impacting due to the lower consumption of electricity during its life cycle. The reliability of the results was proven through a sensitivity analysis of the normalization and characterization factors, which consisted of comparing the results obtained by applying two different methodologies. It is believed that the LCA study carried out can assist in the decision-making process regarding the choice of the most sustainable construction method.

New Criteria

In Austria, the public procurement of construction works is mainly based on two different types-the lowest acquisition costs and the most economically advantageous tender. The first one only considers the price, which means, that the contract is awarded to the bidder with the cheapest price. The other principle refers to the most economically advantageous tender, which has to be chosen for projects that exceed a certain overall tender value or are related to projects with higher complexity. This principle focuses on considering other awarding factors besides the price, but it often fails its purpose due to the lower weighting of these issues. Over the last years the market has not expanded very much, therefore there is a lot of competition related to the lowest price, which results in inadequate quality and opens up the field for further claims. In order to end the tense price competition among the competitors and to increase the quality of the projects, new criteria with serious weighting will be needed and to fulfill the most economically advantageous tender and supporting the focus on construction quality. Even though there are acknowledged guidelines dealing with environmental aspects of construction sites, like the RUMBA guideline (Richtlinien für umweltfreundliche Baustellenabwicklung-Guidelines for Sustainable Construction Site Management). However aspects of sustainability are no common standard within construction processes. To capture the common standards of sustainable measures on construction sites, and the industries’ understanding for environmental topics, research on experts in the field was done. Based on the authors’ acknowledgements, the paper targets the aspects of an environmental friendly construction site and introduces new criteria for the awarding process, and mentions some of the findings such as the “technical equipment expertise” or “sustainable construction site management”.

Performance Evaluation Model

Abstract: This paper proposes a performance evaluation model of sustainability for construction sites. This model was developed bringing together the Lean Construction, Green Building and the Well-being concepts addressed through the triple bottom line concept of sustainability. Following the Design Science approach, the model was applied in three construction sites at the city of Fortaleza, northeast of Brazil. Results are presented to validate the performance evaluation model proposed. It can be observed that the model can handle a range of variables both in terms of possible management actions and in terms of their sustainability outcomes. Different from others performance evaluation models, this artefact takes in consideration actions that are theoretically deemed to promote sustainability (according to particular construction phases) and managerial actions that are actually implemented. Finally, graphical displays help to guide how sustainability might improve over time, either evaluating individual sites against their previous records or benchmarking different building projects among different construction companies.

Growth Indicator

Construction industry is an important growth indicator because it generates investment opportunities across multiple related sectors. The construction task or work environment is very risky and hazardous and its susceptibility to accident. The major cause of the accident is the employees' poor safety performance in construction sites. These root causes of accidents and factors influencing them need to be studied in order to improve safety results. In pipeline sleeper construction, safety is a dynamic decision issue close to normal construction cases. The study identifies the critical risk factors affecting the safety performance and ways to achieve sustainability in pipeline sleeper construction to counteract the risk of accident occurrence. Based on the evaluation of the questionnaire survey, the study explains twelve most important factors and sub factors, which were rated to have more than a moderate effect on safety performance.
