Impact of Risk on Performance of Design and Build Projects in Lagos State, Nigeria

＂Design and Build＂ procurement method has been in use in Nigeria and this method has been latent with a lot of risks. This study intends to identify the risk inherent in ＂Design and Build＂ and also to evaluate the impact of the identified risks on project performance. A descriptive research survey is undertaken for this study. Snowballing sampling technique was used via the use of questionnaires. Population of the study includes contracting organizations, consultants and clients＇ organizations that are recently involved in ＂Design and Build＂ projects. A total of 39 questionnaires were distributed and 27 were returned and used for the analysis. Statistical Package for Social Sciences was used for analyzing the data collected. Descriptive statistical tool of mean item score was employed for the analysis. The results show that the most prominent risk is change in quantity/scope of work in terms of cost related risk while in terms of time related risks the most prominent risk is design changes. Errors and omissions during construction are the risks prominent in terms of quality. In conclusion, ＂Design and Build＂ procurement has a lot of inherent, unresolved and undefined cost, time and quality related factors that can trigger off risks that will affect performance of DB project. Implications of this study to practitioners in the construction is such that the findings of this study can create awareness for stakeholders and construction practitioners of the prominent risks that affect DB projects and this can help in better management of future DB projects in Nigeria and other developing countries. Design and Build procurement in spite of these plethora of risks is still strongly recommended for clients, stakeholders and other practitioners in the construction industry for use in their future projects. This procurement method delivers project faster, within cost and offers good quality of workmanship and product to users of this method.

ASSESSING THE LINK BETWEEN PUBLIC OPINION AND SOCIAL SUSTAINABILITY IN BUILDING AND INFRASTRUCTURE PROJECTS

Increasing the use of social sustainability in the decision-making process for build-ing and infrastructure projects requires that it be defined such that it can be evaluated objectively.One potential indicator of social sustainability in infrastruc-ture projects is public opinion,which can provide a means to evaluate the level of social sustainability on a project based on personal values.Public opinion includes both support and opposition for a project.In this study,the causes or triggers for public opposition to a construction project are identified and then compared to principles of social sustainability to determine if they are related.Eight case study projects were used to identify common triggers of public opposition.The results suggest that common triggers of public opposition are related to land acquisition,escalating construction costs and the presence of endangered species on the project site.Eight of the twelve principles of social sustainability that were identified were determined to be related to public opposition.The results of this study suggest that public opposition could be used as a measure for some elements of social sus-tainability but that further research into other measures for social sustainability is necessary.

Inter-Organizational Conflict (IOC) in Building Refurbishment Projects;an Exploratory Factor Analysis (EFA) approach

Over the past years,there has been an expanding intrigued in building refurbishment projects because of the alter in financial conditions and the accentuation on sustainable development.Increasing demand for building refurbishment projects will lead to an increase in organizational interactions in the construction works as building refurbishment works involve interactions among many different organizations and it can cause Inter-Organizational conflict(IOC)among organizations involved in projects.This paper adopted an Exploratory Factor Analysis(EFA)approach to analyses IOC in building refurbishment projects.For this study,a fivepoint Likert Scale was adopted to ensure the instruments of the study are reliable.The researcher ultimately sent questionnaires as a web-link and email invitation to 1050 construction firms and 733 architectural firms.The questionnaire sent to managers and professionals from construction and architectural firms in Malaysia.Finally,one-hundred-seventy-nine(179)refurbishment projects formed a database for this paper.The finding of this paper shows the IOC factors that contribute to the improve the performance of building refurbishment project can be conflict during the construction stage,conflict between the client and the consultant,task expectations,basic responsibilities,final duration,project’s goals,conflict between the client and the contractor,final cost,final quality,standards of behaviors,conflict between the contractor and the consultant,interference and conflict during the design stage.

Development of Human Resources for GEN （Generation） II1＋ New Build Projects

After a long period without new NPPs （nuclear power plants） being designed or constructed in Europe, new build projects have been prepared, planned and are now under construction. The majority of these projects involve a new design with an enhanced level of safety, called GEN （Generation） III＋. Although the serious events at the Japanese Fukushima Daiichi NPP caused by a tsunami led to a reduction in the number of new projects or even a phase out of nuclear power in some countries, only a slight reduction or delay of projects is expected globally. GEN III＋ new build projects give rise to several economical, technical, human resource and organizational challenges. The paper starts with a discussion of these challenges and presents several activities that have been started to deal with them. It focuses on the development of human resources, coordinated approach of operators and suppliers can lead to the needs-oriented human resources development. particularly with operators and suppliers of GEN III＋ NPPs. Only a successful execution of these projects. The focus must be on the

Analysis of Causes of Delay in Middle and High Income Self-Build Housing Projects (SBHPs) in Wa, Ghana

Self-build housing projects (SBHPs) among middle and high income developers are faced with many challenges that cause delay in the delivery time of the house(s). The focus of this paper is to analyse the factors that cause delay in SBHPs in order to identify the critical delay factors. Review of literature and expert input revealed 20 variables which were used in a structured questionnaire for data collection from owners, consultants and builders in Wa Municipality. Reliability test, t-test analysis and mean ranking were used in the data analysis. The results revealed that “Delay in obtaining permit from Local Authorities” was the first delay factor followed by “Poor site management and supervision”. The delay factor ranked least was “Inadequate cost estimation and related details” from consultants. The paper recommends that Government agencies that regulate physical development should intensify public education, particularly on responsibilities and obligations, especially among self-builders. The paper recommends further study into labour-related issues as well as communication and information management among participants and its impact on self-build project success.

Contract Types That Bring Most Value by BIM to Construction Project Involving BIM

Building information modelling(BIM),which is a new tool to manage information relating to a construction project throughout its entire life cycle,has been a hot discussion topic in the industry in recent years.With the many capabilities it can offer,some early adaptors have applied it to solve problems in various areas including utilities.From their practical experience,it is learnt that we need to change our current workflow to apply BIM before the maximum benefits can be gained.The selection of project delivery method or contract type to manage a project defines the workflow and plays an important factor to the success of BIM adoption.This paper will study the problems in applying BIM on traditional project delivery method;other new contract types available in the market;and how they can bring further value in BIM implementation with examples from different countries.
