Existing concrete structures are also deteriorating and require repair or replacement. In this study, multivariate methods of factor analysis (FA) and cluster analysis (CA), were applied to analyze the liquefied samples datasets for clean and contaminated (sewage) water obtained in Ado- Odo Ota, Ogun State, Nigeria. FA clearly identified two groups of liquefied samples and indicated that the bacterial parameters are higher in fermented locust beans water which can be likened to presence of bacillus subtilis food type. Hierarchical cluster grouped 40 samples into two which are high and low levels of bacteria contents respectively. Descriptive statistics showed all parameters significantly (conductivity, TDS, BOD, COD, carbondioxide, Calcium, Chlorine, pH, Temperature, sali...

This has led to housing shortages and the need for many housing schemes. Many Residential housing developments do not reflect the desired housing needs of the end-users in terms of satisfaction and sustainability, despite a growing interest in green buildings among the various stake holders. Previous research efforts showed that the results are still uncertain and conflicting. Nonetheless, such studies have exposed the main variables especially the human factors affecting green building projects such as different success criteria, divergent success factors and lack of common or shared perspectives among the stake holders. Incorporating green building features are at the developer’s disposal but should align with the potential end-users preferences as it affects the rentals and sales values of such developments. The aim of this...
