Effect of Safety Measures on the Productivity of Column Reinforcement

Abstract

      The purpose of this research is to study the effect of a safety measures provided for column reinforcement activity on productivity by studying a construction of buildings in Bangkok. The safety measures composed of (1) stable scaffolding system, (2) providing clean and not slip walkways on the scaffold, (3) installation of handrails not less than 0.90 meters in height, (4) installing stairs, and (5) providing personal protective equipment for workers. It was found that productivity rates for prior and after the used of safety measures were 11.06 and 8.80 kg. /person/hr., respectively. The productivity declines for approximately 20.43 %, the working time for column reinforcement could take longer for 13.18 % and labor cost could increase for 13.32 %.
