The sources of construction business for local firms have been shifted gradually to oversea market over years due to domestic economic recession. Nevertheless, the revenue seems standstill against to the growing contract amounts since the cost has been encroached on the present cost estimation procedure which based on personal instincts, experiences and simple formula that out of ability to identify the future uncertainties and frame the flexible management in advance under drastic business environment. To enhance the managerial insight and flexibility of evaluation process for the future uncertainties, we proposed and constructed a real optional model of risk cost upon traditional cost evaluation process. As a result of experiment, the sources of uncertainties and the flexibilities for management could be observed and directed clearly to against the risk without subjective or instinctive recognization anymore. Seveal occasions of application of real option value have been suggested in this study several important key points should be emphasized before using it: neither profit/loss nor price for accounting can be promised with the real option value; rather an expectable goal for managers to achieve. Appropriate flexible activities should be studied and approached before making decisions to acquire real option value. Maximized overall real option value could be a powerful competition tool for any company that tries to adopt real option approach to profit estimation if the interaction and synergy of real option among individual projects could be integrated effectively. Under the support of authority and interorganization commitment, the real option process should be learned and modified evolutionary according to dynamic business environment then becomes a strategic advantage.

The main aim of this research is to investigate how elements of the dynamic and temporary team environment of construction project teams influence trust, commitment, satisfaction and learning in the teams. While much can be learnt from the current literature about teams, the theories have mainly derived and focused on teams from permanent environments such as manufacturing, hospitality, health care, education and technology sectors. The uniqueness of construction project teams (for example, temporariness and multi-organisations involvement) creates a team working environment different from common permanent work teams. As such, numerous questions arise when we consider how construction project teams function and how the members are influenced by the temporary and dynamic team environment. For example, how do the project team members establish trust and commitment in the project team environment? How does the interdependency on each other to accomplish their assigned tasks influence individual members?? attitudes and learning in the project teams? The research adopted a cross-sectional mixed method research design employing both quantitative and qualitative methods of data collection in Singapore construction industry. The quantitative method involved survey questionnaires collected from 136 construction practitioners from 47 project teams. The qualitative method involved in-depth interviews with 28 construction practitioners. Quantitative statistical analysis was performed on the survey data using Statistical Package for Social Scientists (SPSS) and qualitative thematic analysis was performed on the interview data using computer-assisted qualitative data analysis software - NVivo. Amongst other things the research findings indicated that individual team members?? perceived task interdependence and reward interdependence are positively related to their trust and commitment in the team. Additionally, their satisfaction in the team played a mediating role between the relationships. With respect to team learning, the research found that team goals, task interdependence and reward interdependence influence team learning, and team learning contributes to the performance of project teams. On a broad view, the circumstances in which how team members?? trust, commitment, satisfaction and team learning are influenced appear to be similar with other work teams. However, in-depth interviews with construction professionals revealed many complex and subtle factors relating specifically to construction project teams, such as, multi-projects and multi-organisations involvement, and degree of familiarity between the members before the team is set up. These factors are central to the team members. In conclusion, this study has brought insights into how temporary construction project team environment influence members?? team attitudes and team learning experience.

Productivity improvement within the construction industry has addressed issues that are predominantly associated with activities and tasks on construction sites, and less so in the office work. The lack of an understanding of the proportion of productive time during working hours for designers, as well as the measurement method forms a significant gap in the knowledge of the design process. Productivity management cycle comprised of 4 phases: measurement; evaluation; planning; and improvement. Therefore, measurement becomes essential in productivity improvement. This study identifies the lack of defined duration for design task and measurement of design activity time as an essential gap in the productivity knowledge that relates to designers.

1 Abstract The main aim of this thesis is to analyze available information on the claim management in the international capital construction. The thesis also describes how the claim management should work and makes a comparison and evaluation of the real situation in practice. This comparison and evaluation is based on FIDIC conditions of contract available to the experts in implementation of construction projects. The thesis is divided into five chapters. The chapters deals step by step with the basic terms, the FIDIC conditions of contract, the contract price, the time for completion, the claim and the claim management. Chapter One clarifies essential terms for understanding the solved theme, the project of construction, the unification of obligations, the foreign business and the construction project organization. Second chapter deals with the FIDIC conditions of contract, which can be classified as a part of lex mercatoria, factually lex constructionis. The FIDIC conditions of contract are used in the foreign construction, but also domestically. Czech civil code inclines to the autonomy of contractual parties and gives businessmen the possibility to determine part of the content with reference to the certain contractual terms and conditions. The FIDIC conditions of contract are judged with the projects...

This thesis proposes a classification system of risk mitigation strategies based on literature search and industry interviews. Following that, a list of generic properties was generated to describe individual strategies. In parallel, populating the properties of a large number of identified strategies was attempted. The practical implications are discussed mainly focusing on knowledge management for risk mitigation strategies.

The thesis deals with evaluation of tenders for communal construction procurement. Each year the public procurement equals the value of millions of Swedish kronors, of which construction projects makes up a large proportion. These projects tend to often exceed their budgets. The aim with the thesis is to investigate if there are faults in the tender evaluation process. The theoretical framework for the study partly consists of a review on how the communal evaluation work is described in law and practice. A qualitative methodology is applied in the study where four procurement workers are interviewed. Similarities and differences between evaluation work in practice and what is described in the study's theoretical framework is been analyzed. One of several conclusions of the study is that the choice of contractual form for the construction work often determines the choice of procurement form. Hence the person that works with modeling of tender documents should be well acquainted with the construction industry. A boundary that was set for the study is that it geographically covers Sweden exclusively. Suggestions for further research include investigating why international construction companies bidding in Sweden on communal construction projects do not seem to function properly.

This study collected relevant data of construction sites between January 1990 and December 2011 to estimate the emission factors of various construction projects for Kaohsiung City using Jhang¡¦s equations. The emission factors of various construction projects are as follows: about 0.121 kg/m2/month for reinforced concrete construction, about 0.141 kg/m2/month for steel constructed buildings, 0.228 kg/m2/month for road (tunnel) works, 0.126 kg/m2/month for bridge works, 0.101 tons/ha/month for regional construction projects, and 0.223 kg/m2/month for others. Based on these emission factors, the total fugitive dust emissions for 2,011 construction projects is estimated to be about 22,087.98 tons, and the exposure of per unit area to the fugitive dust pollution is approximately 11.98 ton/km2/month. The total fugitive dust emissions of 2,011 construction projects is estimated about 10528.14 tons (based on Kaohsiung City construction information database). According to the Department of Land, Kaohsiung City Government, Kaohsiung city is 27.8 kilometers from south to north, 10.4 kilometers from west to east, and the administrative area is 153.6029 square kilometers. The exposure of per unit area to the fugitive dust pollution is about 5.71 ton/km2/months.

In the construction industry, the adoption of concurrent engineering principles requires the development of effective enabling IT tools. Such tools need to address specific areas of need in the implementation of concurrent engineering in construction. Collaborative decision-making is an important area in this regard. A review of existing works has shown that none of the existing approaches to collaborative decision-making adequately addresses the needs of distributed construction project teams. The review also reveals that fuzzy logic offers great potential for application to collaborative decision-making. This thesis describes a Web-based collaborative decision-making system for construction project teams using fuzzy logic. Fuzzy logic is applied to tackle uncertainties and imprecision during the decision-making process. The prototype system is designed as Web-based to cope with the difficulty in the case where project team members are geographically distributed and physical meetings are inconvenient/or expensive. The prototype was developed into a Web-based software using Java and allows a virtual meeting to be held within a construction project team via a client-server system. The prototype system also supports objectivity in group decision-making and the approach encapsulated in the prototype system can be used for generic decision-making scenarios. The system implementation revealed that collaborative decision-making within a virtual construction project team can be significantly enhanced by the use of a fuzzybased approach. A generic scenario and a construction scenario were used to evaluate the system and the evaluation confirmed that the system does proffer many benefits in facilitating collaborative decision-making in construction. It is concluded that the prototype decision-making system represents a unique and innovative approach to collaborative decision-making in construction project teams. It not only contributes to the implementation of concurrent engineering in construction, but also it represents a substantial advance over existing approaches.

This research is an in-depth study concerning the practice of Risk and Opportunity (R&O) assessment during the early phases of major project alliances in Australia. The particular focus is on how R&Os are assessed and how the profile of R&Os are set up and transferred during tender phases (from pre-tender, tender development, through to tender negotiation and construction start-up). The motivation for this research was that project risk assessments are reported to be inadequately assessed and ineffectively managed throughout the project life cycle in spite of the existence of well developed theories and procedures. However, little is known factually about how effectively R&Os are actually assessed in practice during the early project phases, the factors that influence the risk assessment performance and the nature of the issues causing the deficiency of the tender risk assessment system. Although much has been written on the theoretical development of risk assessment systems, tools and techniques, very few studies have been conducted to discover empirically how both risks and opportunities are actually assessed during the tender phase in construction practice. These problems suggest that there is a need for in-depth studies of the practice of R&O management, in order to better understand the fundamental nature of the issues that might be causing the reported ineffectiveness of current risk management practice as a basis for improvements. The researcher was immersed in the actual projects at critical stages in order to gain fine-grained access to investigate the issues ‘in situ.’ Four major construction project alliances were selected for in-depth investigation, from amongst twenty large mining and construction projects considered in the course of this research. The research methodology used centred on participant observations and document analysis supported by interviews, discussions and mini-surveys to triangulate the findings. Data were gathered and analysed on how information and rapport associated knowledge of R&Os were captured, converted and transferred during tender phases, from pre-tender, tender development, commercial negotiation up to construction start-up. Risk assessment systems, tools and techniques used during the tender phase in the projects studied were first examined and analysed. This revealed the R&O assessment profile transfer process plus its variatious patterns, the associated practical problems and gaps in both theoretical models as well as practical implementation. The process and analysis were then interpreted and modelled using the four modes of the SECI (Socialisation-Externalisation-Combination-Internalisation) model developed in Organizational Knowledge Creation Theory (Nonaka and Takeuchi, 1995). This provided a better understanding about the fundamental nature of the issues that might be causing the reported inadequacies of current practice. Implications of this knowledge conversion perspective for the adoption of risk assessment tools and techniques were identified. The major findings of this research are: (1) The R&O assessment profile transfer across the tender phases described as an information transfer model, reveals that while considerable effort goes into formal R&O documentation during the tender phase, there are a number of “breakdowns” in the assessment process. The two most critical issues are the disconnections between the quantitative assessment process and qualitative process, and a discontinuous process during hand-over from the tender phase to construction start-up phase; (2) These breakdowns can be explained when the R&O assessment process is modelled as a knowledge conversion and transfer process rather than an information transfer process described in finding 1. The analysis reveals subsequent knowledge losses during the process and knowledge gaps between theory and practice. People, process and technology factors influencing tender risk assessment are also discussed; (3) Viewing R&O assessment as a knowledge conversion process points to the need for the adoption of tools that can enhance the effectiveness of risk assessment through a knowledge elicitation, capture, communication and consolidation process; (4) The study proposes the SECI model as a suitable framework to better understand the nature of reported problems and reveals possible explanations for the deficiencies in the R&O assessment systems observed in practice. These major thesis findings provide an alternative way of looking at risk assessment, shifting risk assessment from an information-based process to a knowledge conversion-based approach for a more sustainable and effective R&O assessment system. Using the SECI model to describe risk and opportunity assessment processes as a knowledge conversion process has major implications for education and training in the practice of R&O assessment. R&O assessment becomes a learning process rather than a mere information passing process. Knowledge is revealed and captured and becomes internalised as an integral part of R&O assessment. This helps to explain why attempts to capture “lessons learned” as a separate of conventional R&O procedures frequently fail. Alliances and similar modes of project delivery that involve the collaboration of many stakeholders are likely to be used increasingly in construction, and it is essential we understand the ways in which information and knowledge of risks and opportunities are managed, especially in the early phases of major projects. Thus the new insights provided by these findings have significant implications for the formation and operation of risk and opportunity procedures in alliances and major projects more generally. Project alliance is recommended as a good procurement strategy that can enhance the effective transfer and use of knowledge about project uncertainties, thus assisting project organizations in achieving an effective risk management performance. Future research is needed to further explore the relationship between the characteristics of project alliances and the effectiveness of risk management over the whole project life cycle, with the support of the analysis framework from knowledge conversion process proposed in this thesis. Building on these findings, future research work is needed to understand how to effectively enhance the conversion of tacit knowledge about uncertainty into explicit knowledge. This will aid the development of a practical risk management framework across the whole project life cycle together with supporting risk assessment tools that utilize a knowledge-centered approach. The findings also point to the need for more research on the risk attitudes and related people factors, in the conduct of risk and opportunity assessments across the project life cycle.
