Implementing environmental management systems in construction: lessons from quality systems

Quality has been a key issue in Singapore's construction industry since the late 1980s. ISO 9000 certification is now compulsory for large construction enterprises and is an important feature of the industry. Following the global trend, environmental issues are gaining prominence in the country. A few companies have been certified to the ISO 14000 standard. It is predicted that this standard will have an impact which is similar to that of ISO 9000. Organisations are being urged to implement integrated management systems (IMS).

A study was undertaken to assess the perceptions and expectations of contractors concerning ISO 9000 certification and the costs and benefits in practice. Contractors’ expectations of ISO 14000 certification were also ascertained, together with their environmental awareness, policies and current practices, and their views on measures which could promote its widespread adoption. The study was based on a postal survey. It was found that contractors had derived benefits from ISO 9000 but were driven by short-term cost-benefit considerations. Their attitude to ISO 14000 certification was generally similar. Suggestions for increasing the likelihood of a high uptake of ISO 14000, and IMS are made.

基于GIS的城市设计工作方法探索

基于Auto CAD的城市设计工作方法存在设计与分析相独立、成果无法直接输入管理信息系统等问题,造成设计与问题研究、公众参与、规划管理等工作之间信息流通不畅,也不契合现代城市设计自身的特质。为此,提出基于GIS的城市设计工作方法,并建立起该方法的基本框架和步骤。在此基础上,基于Arc GIS10.0这一软件平台在多个城市设计项目中初步实践了这一方法,并总结该方法的优势和劣势,提出未来可能的发展方向:GIS是城市设计中多种技术、多种软件平台、多来源信息、多个工作阶段相互整合的主要平台。     

A study regarding the environmental management system of ready mixed concrete production in Turkey

The construction industry as one of the leading industries of the Turkish economy makes up approximately 60% of total investments. Because of the widespread use of concrete building systems used in construction work in Turkey, concrete production is also quite high. In this study, the application levels of the methods of environmental management in regards to the ready mixed concrete production in Turkey were determined. In Turkey a wide ranging environmental laws about this subject exists. However, it is known that there are problems in its implementation. As a result of this study, it has been determined that there are differences between plants in their environmental applications of the ready mixed concrete production in Turkey, and despite the strides taken in this area; it has not achieved the desired levels. Therefore, inspections must be increased in order to strengthen the enforcement of the rules and regulations of the environmental laws in Turkey.

On using a communication-mapping model for environmental management (CMEM) to improve environmental performance in project development processes

This paper examines the existing environmental management communications practice among project participants in project development processes. There is a growing pressure for all project participants to extend their traditional business objectives of only lowering cost and shortening project duration to improve environmental performance. In achieving better environmental performance, it is essential to collect responses from project participants including project clients, consultants, contractors and various sub-contractors to build up collaboration. As this collaboration is based largely on communications among various parties, the validity and effectiveness of the communications are essential to enable effective collaboration. By investigating practical applications, this paper identifies gaps of communications among project participants, and shows that these gaps present barriers to the improvement of environmental performance in construction. Possible solutions to communication gaps are investigated, leading to the proposal of a communication-mapping model for environmental management (CMEM). The CMEM is proposed as a method aimed at effectively implementing environmental management in construction practice. Data used for this study are collected from six construction projects in Hong Kong. A free-flow mapping approach is also employed to assist the investigations. It is believed that this study can help improving communications among project participants and environmental performance in the construction industry.

Interdisciplinary research and transdisciplinary processes for environmental management under different socio-natural conditions

Interdisciplinary research and transdisciplinary processes as part of environmental management respond to the increasing complexity of socio-natural changes in recent decades. Two similar studies of eutrophication in raw water reservoirs for drinking water production in Norway and China are used to discuss interdisciplinary research and transdisciplinary processes organised through the DPSIR framework (drivers, pressures, states, impacts, and responses) as instruments for environmental management. The conclusion is that interdisciplinary research and transdisciplinary processes can enhance the understanding of complex socio-natural processes under distinctly different institutional systems. The DPSIR framework was not necessary for achieving the desired result.
