Design organizations play a major role in the construction industry: they are the media that transfer the requirements of the client to the contractor and ensure that they are met. Thus they need to provide a high quality of service to ensure that their client's project achieves the best possible standards of cost, time and quality. Seventy quality practices (QP) were identified as having a bearing on the quality of service provided by the local design organizations. These quality practices were grouped into fifteen sections termed quality sections (QS). The prevalence of these practices among the local design organizations was surveyed and determined. The results indicate a significant need for improvement in the quality sections ‘working relationship’, ‘employee training and education’, and ‘performance quality audit’. The study reveals the need for the establishment of a design code, and evaluation standards for local design organizations.  相似文献

This study evaluates primary and secondary data from two districts to assess the status of asset management practices, and to examine requirements for improved asset management. Asset inventory data shows that asset management practices in the districts are currently poor, leading to high rates of nonfunctionality and low service levels. The existing ‘fix on failure’ approach to water systems’ repair has become a common practice. However, many repairs which relied on ‘fix on failure’ were found to have delayed, often due to the length of time it takes to mobilise financial resources from ‘post‐paid’ water users. This paper contends that without an improved asset maintenance, system it is likely that rural water systems in Ghana will continue to provide unsustainable services. The Findings demonstrate that improving the current asset management practices is dependent on human and financial resources, access to timely water service monitoring data at district levels, and planning and budgeting regime to reflect life cycle costs of water systems.  相似文献

The construction industry of Hong Kong has a very poor site safety record. The overall accident rate has gone down a little during the last few years, but the number of fatalities has risen dramatically. In the past, the Hong Kong Government adopted a laissez-faire approach in managing construction safety, hoping that market forces would regulate the safety performance. However, the approach has proved to be ineffective. Since 1986, the Government has taken a proactive approach in combating construction site safety, and has introduced a series of safety programmes, which consist of encouraged and mandatory schemes aiming at nourishing a proper safety culture in the construction industry. Recently, the Government decided to criminalize site accident cases by introducing a so-called ‘Supervision Plan’, aiming at changing the safety attitude and culture of construction practitioners. This paper applies an attitude-changing model, ‘reinforcement theory’, to predict the changing attitude of people in the construction industry. The results show that the attitude of construction practitioners in Hong Kong will change to be more positive when they receive more messages to confirm that people really are put into jail for negligence under the Supervision Plan.  相似文献

Knowledge management (KM) is of increasing interest to a number of leading UK construction organizations. Companies are keen to find out what other organizations are doing both within the construction and other industry sectors. There are important lessons to be learned from Canadian oil and gas organizations on how they manage their knowledge. A case study is used to explore the KM activities of eight leading organizations and investigate the opportunities for construction organizations to adopt some of their ideas. Three areas are covered: KM strategy and implementation, people aspects of KM and metrics for KM performance. There are several potential lessons for UK organizations: the need for KM to be driven by senior management if it is to have any notable success; the use of people‐centred techniques for sharing tacit knowledge and IT tools for sharing explicit knowledge; the importance of selling solutions to project teams to obtain employee support for KM; peer recognition has a more sustainable impact than financial reward; and KM measurement should be considered as a way of improving its impact, rather than justifying expenditure.  相似文献

‘Collaborative working’ and ‘prototyping’ have both been identified by many within the industry as two methods of working that can help organisations become more profitable and productive. However, when used collectively the potential exists to bring improvements to the Architectural, Engineering and Construction sectors through the eradication of waste and re-work. The concept of ‘Collaborative Prototyping’ provides a process that challenges existing cultural attitudes and working processes and advocates a change in the way conventional projects are managed, in order to achieve a more competitive industry. This paper presents the results of a study on the evaluation of current Collaborative Prototyping practices within the Architectural, Engineering and Construction industry. It reviews existing collaborative methods of working along with current developments. An evaluation of the role of 3D modelling and prototyping practices has also been conducted, and the current levels of the industry's use are established. This paper concludes that the industry makes little use of Collaborative Prototyping, and therefore at present does not maximise the potential that prototyping and collaborative working offer in improving working practices.  相似文献

The risks to a system must necessarily be well managed for it to be sustainable. In this paper risk, opportunity and vulnerability are clearly distinguished. Managing them for sustainable systems is a set of ‘wicked’ problems with interlocking issues and constraints which can only be solved through a social process. This process can also identify new opportunities to add value. There is a strong need to integrate our understanding and ability to manage ‘hard’ and ‘soft’ systems and this may be done through a way of systems thinking about processes introduced recently (Blockley and Godfrey, 2000). The methodology enables appropriate attributes of processes to be chosen and defined so that evidence can be collected from the past, present and future to steer a ‘wicked’ process to success. This includes a proper consideration of hazards, risks and vulnerabilities and the incorporation of the basic ethical values of sustainability. An example of a (partial) set of processes for sustaining a water supply is given based on an actual case history.  相似文献

The water industry in England and Wales has developed over the last century, from small organisations serving local communities to large integrated companies in private ownership, overseen by a government regulator. Asset management practice has developed greatly in the 17 years since privatisation, with companies able to plan their operations and investment as they believe appropriate for the provision of customer services, subject to justifying their plans to the economic, quality and environmental regulators. Investment has flowed into the industry to replace deteriorated assets and to improve the quality of drinking water and rivers. The asset base is complex and, with a replacement value of approximately £231 billion at the 2002–2003 price base index suitable approaches are required to ensure that both the water service and the sewerage service are delivered at the most appropriate long‐term cost. The 2004 UK water industry price review was supported by the introduction of a Capital Maintenance Planning Common Framework to help companies understand and explain their maintenance investment requirement. In this paper, a service‐performance model is proposed to improve managers' understanding of the way in which businesses and the environment change over time, taking account of maintenance and other strategic requirements. Although developed with the water industry in mind, the model is equally applicable to other asset‐intensive industries.  相似文献

It is possible to detect a shift in the way we think about environmental issues, in particular climate change, from what academics call ‘ecological modernization’ to what can be termed ‘resilient cities’. This is both a consequence and a cause of city regions emerging as the pragmatic scale of governance. This article will use a case study of Greater Manchester in the northwest of England to show how thinking on the environment was centred around ‘ecological modernization’ with an emphasis on business opportunities associated with a move to a low-carbon economy. It will argue that this approach has been enhanced by a new focus on resilience. The case study will use examples of the Ecocities project, green infrastructure and flood risk to show how a concern for resilience has emerged. It will then revisit the issue of energy to show how the new concerns have influenced the low-carbon strategy.  相似文献

‘Plan, monitor and manage’ has recently emerged as the UK government's preferred approach to provision of housing land through the planning system. However, the transition from the previous system of ‘predict and provide’ has been driven by events and lacks conceptual underpinning. The full potential of a more flexible response to changing circumstances may remain unrealized unless allied to changes in the conceptual basis for planning policies involving quantities and dates. The article describes the way in which national policy has evolved, the relevance to this problem of ‘strategic choice’ theory and, using case studies, the implications for practice.  相似文献

Work–life fit occurs when people have the resources required to meet demands such that role performance (both at work and in non-work life domains) is effective. Interviews were conducted with 59 construction workers based in Melbourne, Australia to explore how demands and resources were experienced. Using a systems framework, data were analysed using thematic analysis. Results identified two demand typologies associated with demand-to-demand interaction. Demands operating as ‘influencers’ have a major impact on the conditions of the interdependent demand, while demands operating as ‘creators’ generate a new demand and shape the conditions of that demand. One resource typology related to resource–demand interaction was identified. ‘Enabling resources’ enable an individual to manage multiple demands across multiple domains, and may also enable an individual to manage multiple demands within a single domain. A new conceptual contribution is made to an area in which theory is under-developed, by adopting a systems approach to understanding the dynamic interactions between demands and resources. A lack of fit is damaging for the individual; therefore, it is useful to know that demands and resources are interdependent and these interdependencies will vary according to individuals. Using a systems approach to understanding demands and resources will be helpful to organizations seeking to support workers to achieve optimal work–life fit.  相似文献

Capturing and sharing experiences that may be applicable in several projects is generally recognized as a way of enhancing the performance of construction projects. Several studies have reported difficulties in applying learning approaches that could be applicable for a wide range of projects. The learning behaviour in three types of construction project: housing, service and infrastructure, is examined by the means of a questionnaire study including 51 construction projects and more than 800 responses from clients, designers, contractors’ managers, contractors’ workers and subcontractors. The effects of leadership, openness and influence are considered. Based on a factor analysis, three approaches to learning were identified: organizing for learning, experimenting and networking. While housing project organizations do not demonstrate any specific preferences, service project organizations show a focus on networking and infrastructure project organizations show the highest interest in experimenting. On the basis of these results it can be concluded that learning approaches are dependent on the type of project. Thus adopting different learning approaches for different types of construction project seems to be a more relevant strategy than implementing a ‘one size fits all’ learning approach for all construction project organizations.  相似文献

The wherewithal of achieving best value in private finance initiative (PFI) projects and the associated problems therein are documented. In the UK, PFI has offered a solution to the problem of securing necessary investment at a time of severe public expenditure restraint. In PFI schemes, the public sector clients must secure value for money, while the private sector service providers must genuinely assume responsibility for project risks. A broad‐based investigation into PFI risk management informs the discussion in this paper. It is based on 68 interviews with PFI participants and a case study of eight PFI projects. The research participants comprised of contractors, financial institutions, public sector clients, consultants and facilities management organizations. The qualitative software Atlas.ti was used to analyse the textual data generated. The analysis showed that the achievement of best value requirements through PFI should hinge on: detailed risk analysis and appropriate risk allocation, drive for faster project completion, curtailment in project cost escalation, encouragement of innovation in project development, and maintenance cost being adequately accounted for. Factors that continue to challenge the achievement of best value are: high cost of the PFI procurement process, lengthy and complex negotiations, difficulty in specifying the quality of service, pricing of facility management services, potential conflicts of interests among those involved in the procurement, and the public sector clients' inability to manage consultants.  相似文献

Small construction knowledge‐intensive professional service firms (SCKIPSFs) are becoming increasingly important agents of innovation within the construction industry. The nature and process of innovation in SCKIPSFs, however, is generally considered through the constraining prism of research results generated from significantly different contexts, such as from manufacturing sectors or non‐project based firms. A theory of innovation for SCKIPSFs is developed from a longitudinal 22‐month case study of a small architectural practice. Two forms of knowledge‐based innovation were discerned from the empirical work: exploitative innovation and explorative innovation. ‘Explorative innovation’ was found to be located in immediate ‘new’ project domains, and entailed search, variation, experimentation, activity to solve project‐specific problems; while ‘exploitative innovation’ concentrated on developing generic organisational infrastructure to ‘refine’ and ‘improve the efficiency’ of the firm operations to nurture capability for future activity. The key challenge for SCKIPSFs is to develop and manage an appropriate balance between explorative and exploitative innovation over time in order to generate sustainable competitive advantage.  相似文献

The United States has experienced swings of public and private operation of its water services for more than 150 years. This paper examines the most recent swing, that of remunicipalization. We argue that much of this remunicipalization is taking place for ‘pragmatic’ reasons related to cost savings and service quality, but there are also signs of more ‘politicized’ forms of water remunicipalization taking place, similar to efforts elsewhere in the world where the process has often involved heated ideological debates and mass mobilizations. Combined with a growing politicization of other social, economic, and environmental issues in the US, water remunicipalization could become more politicized in the future, but a fragmented ‘pro-public’ movement, combined with ongoing efforts to outsource water services and growing resistance to remunicipalization from private water companies, may constrain this potential.  相似文献

Decision makers must keep in mind that water services have an invaluable ‘price’ for the public budget and society’s welfare. However, due to the specific features of the service, water utilities are prone to inefficiency. Thus, performance evaluation becomes indispensable to face this constraint. Besides the application of the traditional technique of Data Envelopment Analysis to evaluate the performance of Portuguese water utilities, this study also implements the robust technique of order-m to assess the influence of operational environment on water utilities’ performance. In spite of several reforms, the Portuguese water sector still reveals significant levels of inefficiency, partially caused by an inappropriate operating scale. Concerning the operational environment, it was possible to observe a positive influence of private sector participation, economies of scope, and groundwater sources on efficiency. The influence of the ‘quality of service provided’ was also studied in this performance analysis.  相似文献

Transition to a water-cycle city, a sustainable urban water management future, requires the implementation of centralised and decentralised systems to augment potable water supply, protect waterways and enhance urban liveability. Risk is simultaneously driving and impeding this transition. However, risk perceptions of water practitioners and how they affect practitioner receptivity to future modes of urban water supply are poorly understood. This study characterises risk perceptions and attitudes of Australian urban water practitioners towards alternative water systems and uses a receptivity framework to suggest how receptive practitioners are to these systems. Differences between cities are identified, suggesting how familiarity might influence receptivity. These results can inform strategies to enhance receptivity, including improved communication within the water industry and beyond with its various stakeholders, improved cost-projection frameworks to provide a quantitative metric of the benefits of sustainable water options, and a shift from ‘learning to manage’ to ‘managing to learn’.  相似文献

There has been a frequent misconception in analyses of construction sectors of the national economy: the tendency to describe these activities as ‘an industry’ or a small and stable set of ‘industries’. This has led to confusion. Construction was inappropriately assimilated to various forms of manufacturing industry. Characteristics of the construction process were treated as ‘problems’, to whose solution substantial energies were unnecessarily diverted. There has been muddle about the extent to which macro-level planning is appropriate, notably on R&D strategies and innovation for improved industrial efficiency. Construction projects increasingly use unfamiliar technological bases, comparable to ‘technology fusion’ in other sectors. A more fruitful emphasis may be to regard construction as organized as agglomerations of projects - rather than as a discrete industry or a fixed constellation of firms. The idea of the ‘demand chain’ is introduced.

The paper concludes that a ‘technological paradigm’ should replace the ‘industry paradigm’ and that an enduring question remains to explore what is meant by construction ‘capacity’.  相似文献
