“…It has been established among factor analysts, Tabachnick and Fidell (1989); Child (1990); Siegel and Castellan (1988) and in studies by Egbu (1994); Olubodun (1996; 2000) that the property of multicollinearity is highly undesirable for tests under factor analysis. In other ways the correlations between the owner and builder maintenance attributes should not be extremely high, as this undermines the use of factor technique to detecting common variance among the attributes.…”

“…Olubudun (2000) has cited Child (1990) as having described the essence of factor analysis as likely to benefit any field of research that aspires not only to describe, but also to generate from a given set of data, generalisations, inferences and predictions; to rely on the credence of factor analysis as a statistical tool. Overall and Klett (1972) considered factor analysis, as a reduction technique concerned with relationships among test variates and relationship of the test variates to derived factors.…”

“…Undertaking a good factor analysis relies on the fulfillment of three important criteria (after Overall and Klett, 1972; Egbu, 1994; Olubudun, 2000). These are parsimony, orthogonality and conceptual meaningfulness.…”

This paper seeks to explore and detect underlying relationships between identifiable attributes that are influential to successful outcomes of home maintenance activities. The study's approach is to identify, from the perspective of owner‐occupiers, the attributes that are influential on the successful outcomes of home maintenance activities. The study is primarily based on 186 questionnaire responses from a stratified random sample of owner‐occupiers taken from 12 local authority wards identified on the basis of a Ward Index of Multiple Deprivation. The intercorrelations among the attributes influential to the outcomes of home maintenance activities demanded the application of principal component analysis to determine the factors perceived to dictate home maintenance outcomes. This resulted in the extraction of nine significant factors, which combine to exert their influence on the quality of the maintenance activities in the owner‐occupied sector.

The repercussions from design failures have been the subject of much study. With every passing moment the implications of design defi ciency presents a new set of actions and reactions. In this contemporary technological / scientifi c era, this fi eld of study acts as a ' Testing Lab ' of designers ' ideas. Any part of the globe can serve as a testing fi eld for such studies if there is building design. These studies can help both the designer to improve their skills and industry to develop new materials. Despite current technological advancement, the prevention of unplanned building maintenance is still not being achieved. This research paper highlights examples of design that were not fi nished within the required parameters and thus resulted in faults. The study also highlights the effect of faulty design on building maintenance.

“…Defective construction works can be defined as works that fall short of complying with the express descriptions or requirements of the contract. Accordingly Olubodun [23] states the majority of modern buildings and civil structures are complex and involve the use of a great variety of engineering methods and processes. Therefore, most projects face the possibility of defects and defective work, which generally result in structures that cannot perform their originally intended roles.…”

Aim: The aim of this study is to evaluate how faulty design affects construction and maintenance of building projects in Asaba, Delta state with a view to establishing their level of occurrence and providing ways of mitigating them. Study Design: It was a survey research, the study was effected via literature review and a well-structured questionnaire. Likewise, interviews were carried out to substantiate the findings of the questionnaire survey. Place and Duration of the Study: The study was conducted in Asaba, Delta State, Nigeria for a period of 2 years. Methodology: Being a survey research, 80 questionnaires were administered to the respondents and only 67 were returned which represents 84% response rate. The data collected was presented and analysed using tables, frequency, mean score and relative importance index. The analysis was aided by a computer-based software, named Statistical Package of Social Sciences (SPSS) version 22. Results: The study found out that; inadequate structural design, lack of details, lack of inspection, inaccurate measurement, not complying with specification, use of expired materials, wrong use of equipment, inadequate performance of equipment, unclear specification were rated as the most severe defects in each of the groups. Also, the findings showed that defects found in the study are categorized as design deficiencies, material deficiencies, construction deficiencies and subsurface deficiencies. Conclusion: The study concluded recommending that the designers must take into account maintenance issues during design and construction stages. Also, proper sensitization of building contractors with respect to durable materials which are suitable to the immediate environmental condition should be purse as well as the construction techniques and competence of workforce. Likewise, strict quality assurance and quality control (QA/QC) program should be encouraged during project design and construction.
