3CV+2: quality model for dwelling construction

Salvador García Rodríguez, Juan Pablo Solís Flores


This paper presents the model and the results that have been achieved during the development of the National Quality Certification Program based on the model 3cv +2 from June 2005. This program has been developed based on an agreement between the Monterrey Tech and the National Chamber of Housing Industry. Nowadays, the program has 52 voluntary real estate companies from different states of Mexico. The 3cv+2 quality model is a methodology that is always looking for the reduction in the construction processes variability allowed for systematic and continuous evaluation criteria of the quality performance in all construction stages, and allows for developing a systematic continuous improvement process for evaluation of house quality performance. The 3cv+2 model defines three quality criteria (3cv) for the house materials, construction processes and final product, supported by two audits (+2), one internal audit done by the own company, and one external audit done by Monterrey Tech. The model guarantees that the company is using high quality materials, that each construction process adds quality, is productive, is efficient, is rational, and fulfill standards. In this way the materials, labor force, equipments and processes will give a higher quality home value and also quality is guaranteed in all the construction stages.
