Safety in the construction segments is one of the most unprotected within the unorganised labour sector in India. The purpose of the study is to apply data envelopment analysis (DEA) to evaluate safety performance of construction segments in India. Essentially, DEA takes into account the input and output components of a decision making unit, calculates technical efficiency, and is treated as an indicator for safety performance of Decision Making Units (DMUs). Fifty Indian construction organisations under infrastructure and real estate segments are selected for the study. The findings show that safety performance in the real estate segment is consistently low.
