Considerations for Building Projects Execution, Monitoring and Control in Parts of Nigeria (Published)

There are several materials used in building construction projects. The choice and use of these materials depend on availability, local conditions, technology available and practices of the industry among others. Therefore, this study assessed factors influencing lack of knowledge of properties of materials by the building project supervisors and the effects of not considering their properties during execution of the projects in the study areas. Using survey design to obtain the relevant information through questionnaire administration, a sample size of 222 professionals involved in various building projects design and supervision and urban development in the study areas were selected using a stratified random sampling technique. Descriptive and inferential statistical tools were used to analyse the data collected. The findings revealed that non familiarity with the properties of fresh concrete (4.07), neglect of considerations for strength of materials during execution of building projects (4.06) (F=106.476; p<0.05). Building failure (3.83), and building collapse (3.42); F (129.749; <0.05). These were the factors and effects of not considering properties of materials in the study areas, thereby leading to structural failure. It was recommended that Building Ccollapse Preventive Guide of Nigeria should be organising on the job training for construction workers in the informal sector of the construction industry.
