Beyond the barriers : road construction safety issues from the office and the roadside

Conceptually, the management of safety at roadworks can be seen in a three level framework. At the regulatory level, roadworks operate at the interface between the work environment, governed by workplace health and safety regulations, and the road environment, which is subject to road traffic regulations and practices. At the organizational level, national, state and local governments plan and purchase road construction and maintenance which are then delivered in-house or tendered out to large construction companies who often subcontract multiple smaller companies to supply services and labor. At the operational level, roadworks are difficult to isolate from the general public, hindering effective occupational health and safety controls. This study, from the State of Queensland, Australia, examines how well this tripartite framework functions. It includes reviews of organizational policy and procedures documents; interviews with 24 subject matter experts from various road construction and maintenance organizations, and on-site interviews with 66 road construction personnel. The study identified several factors influencing the translation of safety policies into practice including the cost of safety measures in the context of competitive tendering, lack of firm evidence of the effectiveness of safety measures, and pressures to minimize disruption to the travelling public.

Analyzing causes for reworks in construction projects in China

Although rework is a common phenomenon in the Chinese construction industry and significantly affects project success, the reasons for rework remain largely unknown and most construction companies are unable to manage the issue effectively. To investigate the causes of rework in construction projects, a total of 39 causes were first identified through a comprehensive literature review and semi-structured interviews with 13 experienced construction professionals in China. A questionnaire survey was further conducted to prioritize these causes, in which unclear project process management, poor quality of construction technology, and the use of poor construction materials rank the highest. Finally, a factor analysis revealed 11 major underlying dimensions of these causes, relating to design management, communication management, field management, project scope management, project process management, active rework, project plan changes, subcontractor management, contract management, owner capability, and the external environment. The contribution of this work lies in its examination of the underlying causes of rework perceived by construction professionals in the world’s largest developing country, which is characterized by its unique economic and social systems. In particular, newly identified causes of contract management, active rework, and scope management help expand existing knowledge of the underlying causes of rework for the global construction community.

Barriers to good occupational health and safety (OHS) practices by small construction firms

The construction industry has long been considered to have unacceptably high injury and fatality rates. Previous research has shown that small construction companies sustain higher injury rates than large companies. However, despite the industry being dominated by a very large number of such small companies, little is known of their occupational health and safety (OHS) needs, practices and constraints. This paper takes a first step in aiming to identify the principal barriers that affect good OHS performance of small construction companies so that effective OHS practices can be developed to improve this in future. The contents of the literature are first summarised, in which three critical barriers to good OHS practice in small construction firms are proposed. They are : cost, time, lack of safety awareness and concern. The results of a questionnaire survey carried out with South East Queensland construction personnel are presented, which largely confirm what is suggested by the literature research and also succeed in providing an indication of their ranking in terms of importance and suggestions for overcoming these barriers. The research results provide a better understanding of the issues that restrict good OHS practice in small construction companies and potential measures for improvement.

How Australian construction contractors responded to the economic downturn

The Global Financial Crisis (GFC) in 2008 had a significant impact on the world economy and the construction industry was no exception. This study investigates the major impacts of the 2008 GFC on the Australian construction industry and, in particular how the Australian construction contractors responded to the economic downturn. A total of 35 senior managers from the Top 100 Australian construction companies were interviewed. The findings indicate that construction companies, particularly the large ones were not affected in any significant way but are expecting some difficult financial times over the next few years and are taking actions to minimize the upcoming adverse impacts. The most common strategy adopted by Australian construction contractors is to concentrate on core business while avoiding aimless bidding. Similarly, great focus is placed on retaining human resources in order to maintain the skill set so that the company can respond quickly when market conditions improves. The research findings will provide construction contractors with insights on how to establish and sustain competitive advantages during economic slowdown and become more resilient in the future.

Identification of Materials from Construction Site Images Using Content Based Image Retrieval Techniques

The capability to automatically identify shapes, objects and materials from the image content through direct and indirect methodologies has enabled the development of several civil engineering related applications that assist in the design, construction and maintenance of construction projects. Examples include surface cracks detection, assessment of fire-damaged mortar, fatigue evaluation of asphalt mixes, aggregate shape measurements, velocimentry, vehicles detection, pore size distribution in geotextiles, damage detection and others. This capability is a product of the technological breakthroughs in the area of Image and Video Processing that has allowed for the development of a large number of digital imaging applications in all industries ranging from the well established medical diagnostic tools (magnetic resonance imaging, spectroscopy and nuclear medical imaging) to image searching mechanisms (image matching, content based image retrieval). Content based image retrieval techniques can also assist in the automated recognition of materials in construction site images and thus enable the development of reliable methods for image classification and retrieval. The amount of original imaging information produced yearly in the construction industry during the last decade has experienced a tremendous growth. Digital cameras and image databases are gradually replacing traditional photography while owners demand complete site photograph logs and engineers store thousands of images for each project to use in a number of construction management tasks. However, construction companies tend to store images without following any standardized indexing protocols, thus making the manual searching and retrieval a tedious and time-consuming effort. Alternatively, material and object identification techniques can be used for the development of automated, content based, construction site image retrieval methodology. These methods can utilize automatic material or object based indexing to remove the user from the time-consuming and tedious manual classification process. In this paper, a novel material identification methodology is presented. This method utilizes content based image retrieval concepts to match known material samples with material clusters within the image content. The results demonstrate the suitability of this methodology for construction site image retrieval purposes and reveal the capability of existing image processing technologies to accurately identify a wealth of materials from construction site images.

Cross-Cultural Intelligence (CQ): its impact on British Expatriates Adjustment in International Construction Projects

Purpose: The purpose of this paper is to investigate the relationship between the facets of cultural intelligence (CQ) (cognitive, meta-cognitive, motivational and behavioural) and the dimensions of cross-cultural adjustment (interaction, general and work adjustment).

Design/methodology/approach: Interviews and questionnaire survey were carried out with British expatriates from the architectural, engineering and construction sector. A total of 191 respondents, with experience from 29 different countries, actively participated in this research. Structural equation model was subsequently developed to investigate the relationship between elements of CQ and cross-cultural adjustment.

Findings: Results of structural equation modelling revealed that collectively all the four aspects of CQ have significant influence on general, interaction and work adjustment, particularly motivational and cognitive CQ. Cognitive CQ which empowers the expatriates with in-depth knowledge about different cultures was a significant predictor of interaction and work adjustment, whereas, motivational CQ is a significant predictor for general and work adjustment. However, no support was gathered for meta-cognitive and behavioural aspects of CQ.

Practical implications: Globally, construction companies and projects are entering an era of increased internationalisation which has prompted the migration/promotion of British construction professionals to different parts of the world for their specialised capabilities and skills. Thus, it is of utmost importance that these professionals adjust to their new world of varied culture and still be productive in their work.

Originality/value: An understanding of these essential factors can actually help British construction organisations to select and mentor individuals and to provide necessary training for successful international assignments.

Linking response strategies adopted by construction firms during the 2007 economic recession to Porter’s generic strategies

The time period bridging the years 2007 to 2012 will be remembered as one characterised by dramatic changes in the Irish and UK construction industries. Construction companies witnessed unprecedented changes in the environment, namely the coincidence of a sharp economic downturn, the significant decline of public works, a reduction in lending, increased competition, and structural changes in the marketplace. Nevertheless, little has been documented on what response strategies construction companies adopt as a result of an economic recession. Based on four exploratory case studies, a taxonomy framework of the response strategies adopted by Irish and UK construction companies during the 2007 economic recession was developed relative to Porter’s (1980) generic strategies of cost leadership, differentiation, and focus. Porter’s model (1980) is a well known theoretical framework among business strategists and industrial economists worldwide. The analysis provides strong support for the adoption of cost leadership strategies as a means to surviving the 2007 economic recession. The case studies further suggest that cost control initiatives are one of the most important attributes in companies’ responses to the 2007 recession. The findings provide valuable assistance for construction contractors in developing effective strategies and thus reducing business failures during recessionary periods.

Construction sector: Need for strategic reorientation

The construction sector in Portugal declined sharply over the past 10 years. The current crisis can wiped out the entire industry. Can the industry survive? What lessons can we learn? What can be done to revive the sector? These are questions this study intends to answer. By analyzing the best practices of the industry and of the largest construction companies in Portugal, as well as the difficulties and constrains that they all faced, I found that retrenchment (operational costs and selling assets) are the main measures companies resort to, and that strategic reorientation is essential to turnaround. I found that internationalization is a key driver on strategic reorientation and diversification and concentration are complementary strategies that can enforce and strengthen the main one.

Exploring context-awareness in the construction logistics services delivery

Managing a construction project supply chain effectively and efficiently is extremely difficult due to involvement of numerous sectors that are supported by ineffective communication system. An efficient construction supply chain system ensures the delivery of materials and other services to construction site while minimising costs and rewarding all sectors based on value added to the supply chain. The advancement of information, communication and wireless technologies is driving construction companies to deploy supply chain management strategies to seek better outputs. As part of the emerging wireless technologies, contextaware computing capability represents the next generation of ICT to the construction services. Conceptually, context-awareness could be integrated with Web Services in order to ensure the delivery of pertinent information to construction site and enhance construction supply chain collaboration. An initial study has indicated that this integrated system has the potential of serving and improving the construction services delivery through access to context-specific data, information and services on as-needed basis.

Forum - The Stern review: implications for construction

The SternReview(2006) on the economics of climate change has changed the ground onwhich arguments over climate change are fought. In making the economic case for mitigation over adaptation, Stern has sought to undermine one of the primary arguments against decisive early action - that the immediate costs outweigh the long-term benefits. While this argument is made at the global level, it is appropriate to ask what implications Stern's arguments might have at the construction sectoral level. The implications of the Stern Review for construction can be divided into three main questions. How construction would be different if Stern's economics were applied? How would construction companies act differently if Stern's ethics were adopted? How will the political response to the Stern Review change construction's policy and regulatory landscape? The impact of the Review has shifted the debate from the natural science community into the public policy domain and onto an economic rationale. There seems to have been a pronounced shift away from the debate over the science and towards the economics of mitigation versus adaptation. In this context, the academic debate over Stern's methods is irrelevant - it is his findings, authority and use of the hegemonic power of economic argument that carry the day. This is likely to be Stern's true legacy, and through this will come his greatest impact on construction.

SPICE: a business process diagnostic tool for construction projects

The construction sector is under growing pressure to increase productivity and improve quality, most notably in reports by Latham (1994, Constructing the Team, HMSO, London) and Egan (1998, Rethinking Construction, HMSO, London). A major problem for construction companies is the lack of project predictability. One method of increasing predictability and delivering increased customer value is through the systematic management of construction processes. However, the industry has no methodological mechanism to assess process capability and prioritise process improvements. Standardized Process Improvement for Construction Enterprises (SPICE) is a research project that is attempting to develop a stepwise process improvement framework for the construction industry, utilizing experience from the software industry, and in particular the Capability Maturity Model (CMM), which has resulted in significant productivity improvements in the software industry. This paper introduces SPICE concepts and presents the results from two case studies conducted on design and build projects. These studies have provided further in-sight into the relevance and accuracy of the framework, as well as its value for the construction sector.

Critical operational management in international construction

The construction activities of a contractor may physically take place in the home country or overseas, and the latter, particularly of a large company, has an increasing proportion with the globalisation. Globalisation of the construction industry and its market is a trend in every country, Which increases the opportunities of both international construction, and competition or collaboration with foreign construction companies. International construction project management is undertaken in a complicated circumstance, and requires a synthetic management approach. This research aims to establish a primary framework for the critical operational management in achieving international construction projects in a novel construction market.

A preliminary study on human resource management in international construction

As construction companies continue to explore foreign construction markets, various international construction projects are being undertaken in all corners of the world. In an international construction project with many unique and complicated characteristics, human resource management can play a significant role in promoting the efficient use of complex human resources. The aim of this paper is to establish a valid foundation for further research on measuring the impact of human resource management economically for international construction projects. The paper examines human resource management literature and identifies the application of the related management techniques to the construction industry. In addition, the paper uses the literature analysis to describe the nature of human resource management with particular reference to international construction projects. In particular, the research described in this paper identifies economic performance factors in the implementation human resource management in international construction projects. This paper also identifies the social effects of human resource management practices.

The risks and rewards of international construction from an Australian perspective

Very little research has been carried out regarding the risks and rewards of the international construction industry/market from an Australian perspective. A survey was sent to Australian based construction companies known to be operating internationally, to obtain their insights and perspectives on the risks and rewards of the international construction industry/market and international construction projects. Australian based companies have expanded their operations in order to benefit from inducements such as growth, profit and diversification. Continuing globalization and the openness of new markets has also provided significant opportunities to expand for Australian companies. Those Australian construction companies that have been operating abroad have been doing so for 20+ years in the Asia-Pacific and Australasian regions. This is significant as it shows that easily accessible markets are a stepping stone for further overseas expansion. The most commonly rated rewards for operating overseas were growth and profit; which matched the initial reason most companies chose to expand overseas. It was established that the ability to increase long term profitability through diversification was the biggest inducement for Australian construction companies expanding their operations overseas. When asked to rate the risks associated with international construction not one risk was rated significantly higher than the rest which supports the conclusion that the types of risks and rewards associated with each market rarely vary; only the severity and likelihood of occurrence. From an overall Australian perspective this research has established that the reasons and rewards for expanding overseas were the identical. Further that the risks associated with international construction were established as being different and varied depending on the market.

Strategies for the implementation of continuing professional development for SMEs in construction

The Victorian government (in Australia) intends to mandate that all registered building practitioners (RBP) undertake a minimum level of Continuing Professional Development (CPD) as part of the registration process. The introduction of CPD increases the travel costs for construction practitioners; due to the necessity to undertake a minimum level of training. This places an increased burden on construction companies' especially small regional-based firms that are not in a position of financial strength. This research is based on study of training needs of 73 construction companies in Victoria, Australia. The results show that training costs are being unequally weighted towards small regional-based firms; suggesting that the location of the company is a major contributing factor to their ability to meet registration requirements. Regional companies have comparatively high costs for training compared to metropolitan-based firms. Company location is a limiting factor that impacts on the ability of regional firms to implement training programs. This research investigates the notion that increasing registration requirements will improve outcomes for all participants.
