Improving Productivity through Mistake-proofing of Construction Processes

Résumé fourni par la source

Construction defects are always the key concern of the construction industry. Research shows that, the estimated costs of rework for residential construction are almost equal to 4-5% of contract value. One of the successful devices in lean production to eliminate waste caused by errors is 'mistake-proofing' or 'Poka-yoke'. Mistake-proofing is one of the effective approaches that prevents inadvertent errors and helps workers to be mistake-proof and does not allow defective products to flow to next processes. In this paper, application of Poka-yoke to construction industry is investigated. The results show that the construction operations have high potential of mistake-proofing, and therefore the application of Poka-yoke devices can finally lead to drastic promotion in construction industry. At last section, a case study related to the simple operation of a trolley hoist also conducted to evaluate productivity improvement due to the process mistake- proofing in practice.
