Construction industry is one of the devoting force of any country's economy. Around the world, Small Scale Contractors (SSC) has been found to play a significant role in creating jobs, infiltrating new markets and growing the economy in an inspired and inventive way. However, performance of SSCs in developing and minor developed countries is still not in adequate level due to various factors. Poor QS practices is one of the significant factor which affect to the current performance of the SSCs. Hence, this research aims to implement better QS practices to mitigate adverse impact to the small scale contractors due to plenty of poor QS practices. Particularly qualitative research approach was used for this study and accordingly data was collected from semi- structured interviews and analyzed using manual content analysis. Project delays, cost overruns of projects, cash flow problems, unable to win tenders, poor construction quality, delays in payments and contractual disputes were identified as major issues caused by the poor QS practices. This research suggests government to impose laws and regulations, offer tax relieves to contractors and impose legal requirements to participate in CPD sessions to minimize poor QS practices. Further clients and consultants can make timely payments to contractors and key suggestions to contractors are hire experienced and qualified professionals, provide well-coordinated training, adopt new technologies, keep clear and completed drawings and specifications, use cost and time controlling techniques and maintain good record keeping system.
