Thesis Keith Gale 2013This research uses a significant amount of data obtained using the desk researchapproach due to investigation of phenomena between two batches of constructionprojects – those procured using traditional discrete methods verses those engagedthrough a framework agreement with performance mechanisms. Consistent samplingprocesses have been applied because outcomes align with contractual agreementsreferenced through standard procedures (such as start and finish notices). Supportingdata is obtained through the organisations’ controls which are linked to statutoryfunctions – for example, a legal requirement to comply with highways regulationsand a licence to operate on public highways.Comparison of ‘like for like’ data over a long period of time (four years) is assistedby reference to the organisations controls – which for contractual arrangements andstatutory functions have not changed over the period being studied. All projectsincluded within this research are subject to Public Contracts Regulations (2006) andstatutory audits regulated by the Audit Commission.4.7.3 Survey approach – questionnaires and interviewsUse of survey research is a popular method to detect sociological culture because itacknowledges developed principles, theories and accepted research to identify datasources for a discrete research study (Czaja and Blair, 1996). The use ofquestionnaires and structured interviews to gather data for a sample group enablesstatistical analysis to be undertaken and transposition toward a population (Creswell,2003). Although surveys have limitations – such as a low response rates fromquestionnaires, the methods used allow a range of issues to be discovered throughinteraction of the process.Within the paradigm of construction management the role of questionnaire andinterview account for a significant method of data collection. Questionnaires allow awide breath of study to be covered but at a shallow depth. Interviews followingquestionnaires allow probing of issues at greater depth - but resources required tocollect and analyse data is substantial. Nonetheless, as proposed by Cresswell (2003),trends, attitudes and opinions generated through a sample of that population is a validmethod. Sociological/psychological studies also support use of such methods where atechnical class (i.e. a close technical group of people such a linked professionals) isbeing observed.88
