chapter investigates the most appropriate methodology for the proposed research
project, research strategy and the sample selection procedure to be used.
research in this project will use both qualitative and quantitative research
method. The research was both descriptive and explanatory. The research is
descriptive as it attempts to answer the question of what risk management
practices should be included in construction projects planning phase. The
research is explanatory as it seeks to show why such risk management practices
affect the project performance. The research attempts to predict, correlate a
risk management practices at the planning phase with project performance. The
research has a cross sectional design, which involves getting views of
respondents or informants at one point in time.
research is probabilistic rather than deterministic. Risk management is in the
field of human social behavior. The complexity of human social behavior and the
subjective, meaningful and voluntary components of human behavior mean that it
will never be possible to arrive at causal statements that are purely
proposed study was designed to obtain views from consulting architects,
engineers, project managers, quantity surveyors and contractors in regard to
risk management and cost and schedule performance in construction projects.
This research is both qualitative and quantitative .The research will use two
data collection approaches – structured interviews and physical surveys. The
research sample for the interview was selected on a purposive basis, according
to the judgment of the researcher as to who could provide the best information
to achieve the objectives of the study. The research sample comprised of
construction professionals drawn from commercial and civil construction
contracting organizations around Kano Metropolis.
targets populations interview or survey will be related to a specific project.
The survey will obtain recollections of exact field experiences. In order to
gather necessary technical data, respondents were required to be construction
professionals such as architects, project managers or senior site engineers.
population of the study comprised of professionals in the construction Industry
in Kano Metropolis. There were a quite a number of professionals in Kano
metropolis. The key clients in construction industry are Kano State Government,
Bayero University Kano (BUK) and the Kano State University of Science and
Technology (KUT). Both clients have recently undertaken major construction
works in Kano Metropolis. The regulatory Authorities are the Nigerian Institute
Quantity Surveyors, Nigerian Institute of Architects, Tertiary Education Trust
Fund (TETFUND), Kano State Ministry of works and Housing, works departments of
BUK and KUST.
sampling frame will include the list of some professionals within Kano
metropolis as published by the respective registration boards. The sample for
interview will be those clients, consultants and contractors who have been
involved in at least two projects around the metropolis.
Sample and Sampling technique
sampling procedures will be use due to the nature of respondents to be involved
in the study. Lists of professionals who have their offices based in Kano
metropolis will obtain from respective regulatory boards offices. Questionnaire
will be distributed to the respective professionals. Purposive sampling is a
useful sampling method, which allows a researcher to get information from a
sample of the population that one thinks knows most about the subject matter
This will be obtain by Using Yamane (1967:888)
n = 269/1+269(0.05)2
Where N is the
population 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.
questionnaire containing sections will be developed to facilitate data
collection. The first section aimed to collect the background information of
the respondents, e.g. their age, gender, position, education, work experience
and professional background. The second section will include the respondents’
opinion on the aspects of the risk management process through the different
phases. The third section will include an investigation of the
Architect/engineer selection process and the respondents’ opinion on its impact
to project success. The fourth section of the questionnaire will explore how
the site for the project was selected, evaluated and validated. The fifth
section will explore how the needs identification and validation was done in
the project. The sixth section will explore how the budget and schedule
development was done in the project.
Data collection procedure
the available methods in collecting data three methods were adopted. These were
literature review, interviews and questionnaires. Literature was reviewed to
establish what others have documented on the subject matter. Useful information
was collected from seminar and workshop papers, journal papers and Internet
sources. Questionnaires will be use to gather information for the study. The
questionnaires will be delivered by hand. Structured interviews with selected
client and regulator representatives will be conduct to gain information in the
questionnaire will be distributed physically to professionals, and to client or
developer representatives in construction projects.
Data processing and analysis
is an interactive process by which answers are examined to see whether the
results are relevant to each research question (Backstrom & Hursh-Cesar,
1981). Quantitative statistical analysis for questionnaire was done by using
Statistical Package for Social Sciences (SPSS version:220.127.116.11 for MACOS).
Correlation test will be carrying out to determine the relationship between the
independent and the dependent variables in the research. The qualitative data
collected through the interviews will be analyzed qualitatively using thematic
analysis. This process involved reading verbatim transcripts, identifying
possible themes, comparing and contrasting themes, and, identifying structure
among them (Ryan & Bernard, 2000).
