Abstract	Poor workmanship is a major issue in the construction industry, leading to defects, increased costs, and reduced quality of buildings. This study examines the impact of poor workmanship on construction cost and quality through a questionnaire survey and five real-life case studies conducted in semi-urban areas of Maharashtra, India. The survey results show that inadequate training, lack of experience, shortage of skilled labor, and poor supervision are the main causes of poor workmanship. Case study analysis reveals that common defects such as slab cracks, leakage, plaster failure, and poor finishes resulted in significant rework costs, with slab-related defects causing the highest losses. The study concludes that improving worker training, supervision, and site management can significantly reduce defects, control costs, and enhance construction quality.
