The study evaluates the production practices of small-scale sandcrete block production firms in Osun state, Nigeria, with a view to determining whether the practices would lead to the production of blocks which would meet the required standards, and what aspects of their production practices need to be improved. The study covered twelve (12) local government areas in the state. The research instruments used were a questionnaire, measuring tapes and a concrete slab of 300mmx300mmx50mm size. The instruments elicited information on the methods of production as well as sizes and quality of blocks produced. The results indicated that only 40.6% of the blocks tested passed the height drop test, 54.5% of the firms used a 1:12 ratio cement to sand mix instead of the recommended 1:8; 16.8% used ‘rule of thumb’ for batching, while 68.5% produced sub-standard sizes of sandcrete blocks. The study concluded that Nigerian Institute of Building, Nigerian Society of Engineers and the standard organization of Nigeria should be empowered to conduct verification tests and pay regular inspection visits to the firms. Key words: Small-scale, Production Practices, Building Projects Failure, sandcrete Blocks, and Height Drop Test
