Abstract: The fitness of building in meeting client requirements goes further to create value in construction products. Poor constructional works affects the building quality over time and also have negative impact on overall investments for metropolitan, municipal and districts assemblies as well as the budget of the local contractors. Preventing non conformance to construction building requirements and appraising conformance to requirements results into failures found in and after constructional works. Majority of local assembly’s buildings and construction products are vastly exposed to numerous factors including building defects. These are critical as the building defects can physically affect the building appearances as well as damage the structure. This can further affect the safety of the end users. It therefore called for appropriate solutions to mitigate building and or constructional defects for Ketu-South Municipal Assembly. A failed newly constructed building requires all stakeholders including local authorities, consultants, contractors and public to be involved in remedial works. This ultimately increases the risk, delay schedule and cost for the client whiles further defeating the objective of public supplies. The study was undertaken to assess defects and failures on newly constructed buildings projects among indigenous contractors in Ghana. The analysis was done based on the sample size of sixty (60) contractors with ninety one percent (91%) response rate. This was based on four-point Likert-scale. The respondents for this study include construction industry players including K1K2, D1D2 contractors; Project Engineers and Directors from the Ketu-South Municipal Assembly (KSMA) which formed the sample frame of the study. The data was analysed to obtain mean values which were presented in tabular format and ranked accordingly (1st, 2nd, 3rd etc.) for easy reading and interpretation. It was found from the study that peeling paint, foundation failure, frequent design technology changes and dampness among others were common defects and failures on newly constructed buildings in the study area. The findings impact on the cost of construction, increase risk and delays construction scheduled for the client. Mitigating measures including adhering to technical specifications, strict adherence to health and safety regulations, engaging construction professionals among others were suggested.
