As knowledge-intensive organizations, consultant organizations in the construction industry need to manage knowledge effectively to enhance both organizational performance and customer value. This research explores how knowledge creation (KC) opportunities for different consultant professionals such as Architects, Quantity Surveyors and Structural Engineers differ based on the nature of the job they are required to perform. The research was carried out in Sri Lanka using a survey research method. In total, questionnaires were distributed to 213 construction professionals such as Consultant Quantity Surveyors (QS), Consultant Architects, and Consultant Structural Engineers. Research findings highlighted that the job functions of these professionals are less diversified and repetitive in nature. With regard to KC, results revealed that Architects and Engineers have more opportunities compared to Quantity Surveyors. In addition, mixed results were obtained for different knowledge creation modes, namely, socialization, externalization, combination and internalization. The research finally concludes that the nature of the job of the studied professionals lead to different levels of knowledge creation opportunities. This research can be extended to other construction organizations, psychological factors, and on barriers to knowledge creation as future directions.

A widely recognized theme of construction economics suggests that the cost of construction per square metre increases as building height rises. However, after any years, research conducted regarding the height and cost issue have established a classic relationship between those two, well known as a U-shaped curve. This paper describes the study of height-cost relationship of high-rise residential buildings in Shanghai and Hong Kong. Initial findings indicated that the curved relationships of height-cost of residential buildings in Shanghai and Honk Kong exhibit different profiles. The differences suggest that, Honk Kong contractors have more expertise in multi-storey and high-rise construction that contractors in Shanghai; there are disparities in cost depending on whether the building is a private or public sector project; and, additionally, Hong Kong contractors have less experience in buildings over 100 metres. The dissimilarities also imply that different sets of criteria should be applied in the judgment of height affects cost in different locations. Many factors could be contributors, such as the history and experience in constructing residential high-rise buildings, location, linkage and relationships to the neighboring provinces, design and construction regulations, the time gap between two buildings under analysis, and government policy on residential construction.

Construction estimating is the compilation and analysis of many items that influence and contribute to the cost of a project. The purpose of this paper is to identify the essentials factors that affect the accuracy cost estimation, and to show the degree of importance of these factors, in cost estimation of construction projects in the Gaza Strip from the contractors’ perspectives. A questionnaire survey was administered to a sample of 75 project managers eliciting current trends of their perceptions towards 51 factors that were extracted from an extensive literature review and exploratory study. The study found that the main factors that may affect cost estimation are: location of the project, segmentation of the Gaza Strip and limitation of movements between areas, the political situation and closure of the Gaza strip, financial status of the owner and the increase in unit costs of construction materials. It is essentials that contracting companies of various classifications provide training programs for their junior estimators to gain experience in cost estimation. There is an urgent need to review cost estimation practices in terms of education and training required for those responsible for the estimation function.

The growth of the global sustainability agenda has led to the conception of a new business market, most commonly understood as ‘sustainability services’. This paper examines the growth of sustainability services in the built environment in the U.K; a relatively mature market backed up by supporting policy mechanisms and instruments. Drawing on the rise of sustainability services in the UK, the aim of this paper is to explore opportunities for market growth in sustainability services in the built environment and construction sectors. The paper identifies a number of policies that have supported the growth of the sustainability sector in the UK and examines the importance of these policies at the local level. A case study is presented to show the benefits of a sustainability tool being applied by a UK engineering consultancy called Arup. The case study demonstrates how a tool based approach can help to educate project stakeholders, which, in turn, supports the growth of sustainability services. The final section of the paper makes recommendations and identifies opportunities for market growth in sustainability services globally.
Since the late nineties, the theme of ‘Culture’ was seen to become more important within the international CIB-community. The existing W92 ‘Procurement Systems’ established a special Task Group ‘TG23 Culture in Construction’ to explore and investigate in more detail, several aspects related to this theme. Dr. Richard Fellows from University of Bath and Dr. David Seymour from the University of Birmingham in UK, were the ‘driving-community for this theme. They are both specialists in international procurement and business-cultural issues. Within CIB, culture-issues were found to be increasingly recognized as one of the important reasons for specific difficulties within ongoing construction processes (as was also experienced by for example members of CIB W65, ‘Construction Management’). Dr. Richard Fellows and Dr. David Seymour became the first joint-coordinators of this TG23. It also lead to one of the first TG23-publications, defining perspectives on culture in construction (Fellows & Seymour, 2002).

Many construction projects are characterized by conflict, mistrust and bad relation between the many and diverse stakeholders involved. The picture has been of general dissatisfaction, poor performance, and adversarial relationships. The major UK reports by Sir Michael Latham in 1994, and Sir John Egan in 1997 and 2002 addressed issues of mistrust between the client’s professional advisors, contractors and subcontractors, and also placed considerable emphasis on improving productivity through better procurement practices, tendering, condition of contracts and teamwork. Egan’s work, in particular, focused on the need for the Industry to develop a culture of collaboration and partnering.
