3.1IntroductionThischapter investigates the most appropriate methodology for the proposed researchproject, research strategy and the sample selection procedure to be used. 3.2Research DesignTheresearch in this project will use both qualitative and quantitative researchmethod.
The research was both descriptive and explanatory. The research isdescriptive as it attempts to answer the question of what risk managementpractices should be included in construction projects planning phase. Theresearch is explanatory as it seeks to show why such risk management practicesaffect the project performance. The research attempts to predict, correlate arisk management practices at the planning phase with project performance. Theresearch has a cross sectional design, which involves getting views ofrespondents or informants at one point in time.Theresearch is probabilistic rather than deterministic. Risk management is in thefield of human social behavior. The complexity of human social behavior and thesubjective, meaningful and voluntary components of human behavior mean that itwill never be possible to arrive at causal statements that are purelydeterministic.
3.3MethodologyTheproposed study was designed to obtain views from consulting architects,engineers, project managers, quantity surveyors and contractors in regard torisk management and cost and schedule performance in construction projects.This research is both qualitative and quantitative .The research will use twodata collection approaches – structured interviews and physical surveys. Theresearch sample for the interview was selected on a purposive basis, accordingto the judgment of the researcher as to who could provide the best informationto achieve the objectives of the study. The research sample comprised ofconstruction professionals drawn from commercial and civil constructioncontracting organizations around Kano Metropolis.Thetargets populations interview or survey will be related to a specific project.
The survey will obtain recollections of exact field experiences. In order togather necessary technical data, respondents were required to be constructionprofessionals such as architects, project managers or senior site engineers. 3.4PopulationThepopulation of the study comprised of professionals in the construction Industryin Kano Metropolis. There were a quite a number of professionals in Kanometropolis. The key clients in construction industry are Kano State Government,Bayero University Kano (BUK) and the Kano State University of Science andTechnology (KUT). Both clients have recently undertaken major constructionworks in Kano Metropolis.
The regulatory Authorities are the Nigerian InstituteQuantity Surveyors, Nigerian Institute of Architects, Tertiary Education TrustFund (TETFUND), Kano State Ministry of works and Housing, works departments ofBUK and KUST. 3.5Sampling FrameThesampling frame will include the list of some professionals within Kanometropolis as published by the respective registration boards. The sample forinterview will be those clients, consultants and contractors who have beeninvolved in at least two projects around the metropolis. 3.6Sample and Sampling techniqueTwosampling procedures will be use due to the nature of respondents to be involvedin the study.
Lists of professionals who have their offices based in Kanometropolis will obtain from respective regulatory boards offices. Questionnairewill be distributed to the respective professionals. Purposive sampling is auseful sampling method, which allows a researcher to get information from asample of the population that one thinks knows most about the subject matter(Walliman, 2011). This will be obtain by Using Yamane (1967:888)n=N/1+N(e)2n = 269/1+269(0.05)2n=161Where N is thepopulation size; n is the Sample size; and e is the level of 31 precision(Yamane,1967).
A precision level of 5% was assumed for random sampling survey;the sample size was 161. 3.7Research InstrumentsAquestionnaire containing sections will be developed to facilitate datacollection. The first section aimed to collect the background information ofthe respondents, e.g. their age, gender, position, education, work experienceand professional background. The second section will include the respondents’opinion on the aspects of the risk management process through the differentphases. The third section will include an investigation of theArchitect/engineer selection process and the respondents’ opinion on its impactto project success.
The fourth section of the questionnaire will explore howthe site for the project was selected, evaluated and validated. The fifthsection will explore how the needs identification and validation was done inthe project. The sixth section will explore how the budget and scheduledevelopment was done in the project. 3.8Data collection procedureAmongthe available methods in collecting data three methods were adopted. These wereliterature review, interviews and questionnaires. Literature was reviewed toestablish what others have documented on the subject matter.
Useful informationwas collected from seminar and workshop papers, journal papers and Internetsources. Questionnaires will be use to gather information for the study. Thequestionnaires will be delivered by hand. Structured interviews with selectedclient and regulator representatives will be conduct to gain information in thesubject matter.Thequestionnaire will be distributed physically to professionals, and to client ordeveloper representatives in construction projects. 3.9Data processing and analysisAnalysisis an interactive process by which answers are examined to see whether theresults are relevant to each research question (Backstrom & Hursh-Cesar,1981).
Quantitative statistical analysis for questionnaire was done by usingStatistical Package for Social Sciences (SPSS version:184.108.40.206 for MACOS).Correlation test will be carrying out to determine the relationship between theindependent and the dependent variables in the research. The qualitative datacollected through the interviews will be analyzed qualitatively using thematicanalysis.
This process involved reading verbatim transcripts, identifyingpossible themes, comparing and contrasting themes, and, identifying structureamong them (Ryan & Bernard, 2000). REFERENCENCESWalliman, N.(2011). Your Research Project: Designing and Planning Your Work (3rded.).London:Sage.Yamane, T.
