Integration and Application of Lean Principles and Six Sigma in Residential Construction Ying-hua Shan and Zhong-fu Li
Abstract China’s large population size and rapid urbanization process have made the implementation model of residential construction under huge pressure. It is vital for residential developers to adopt the best practices of production planning and control system to ensure the quality requirements of residences. This paper aims at providing a residential production and construction process management tool for homebuilding industry to achieve the quality goal of zero-defect in construction process with exploring the possibilities of integrating Lean Principles and Six Sigma. The necessity and feasibility of integrating both Lean Principles and Six Sigma were conducted. The integration content and process of Lean Six Sigma construction mode were given. Finally, a Lean Six Sigma Construction Model was established to explain the implementation process of this integrated approach in residential construction. Keywords Integration • Lean Principles • Residential construction • Six Sigma

residential construction has been considered one of main approaches to deal with the contradiction between the huge domestic demands for residential housing and relatively backward residential construction mode in China since the 1950s. China’s large population size and rapid urbanization process have propelled it into the ranks of the largest homebuilding nation, with energy consumption proportion from homebuilding continuing at a pace commensurate with its huge amount of housing completed. According to the statistics from “China Statistical Yearbook 2011”, the floor spaces of buildings under construction and completed respectively reached 4,927,636,000 and 1,831,723,000 m2. Besides, China’s urbanization rate is about 45% with 630 million of urban population. To facilitate the estimation, it is assumed that 60% of the population needs to solve the housing problem and the per capita housing area is 25 m2. Then 2.55 billion m2 of housing needs to be built in China. Additionally, the residential area of 20.7 m2 needs increased to impro
