Using post-occupancy evaluation of housing projects to generate value for municipal governments

Abstract

This article presents a value-generation framework for municipalities through the adaptation of the Lean Project Delivery System (LPDS) to the municipal management process. Said process includes the use of learning loops from previous projects to revamp municipal management during design revision, construction supervision and commissioning, and taking into account the final user’s needs and values. This framework allows the municipal management to investigate the user’s value requirements and proposes the Number of Claims per Housing Unit (NCHU) as a performance indicator. A case study describing this method is presented. We analyze the post-occupation information recorded by the Peruvian National Bureau of Consumer Protection (INDECOPI from its acronym in Spanish), classifying the claims according to their root cause. This approach allows us to separate claims originating in the design phase from those originating in the production phase. This paper proposes learning loops for improved project review in the licensing system, with the aim of increasing the value in design, improving site inspection and control, and optimizing the issue of ordinances. This article also includes a critique of current standards and regulations, since in some cases they do not allow municipalities to fulfill the value-in-design requirements.
