Through the years, the concept of Value has been widely discussed covering diverse fields of knowledge, such as marketing, business management, strategy, engineering, design, and the like. Within the construction industry field, highly praised management approaches have been used to deliver Value such as Value Engineering, Value Management and Lean Thinking. As a result of the complex nature of this concept, different definitions, equations and models have been proposed to mainly deliver Value from a customer focused perspective. Therefore, the potential of the construction industry has been usually limited by the fulfilment of individual requirements. Thus, environmental and social issues have been generally managed from a bill payer perspective. During the course of this research, Chilean experience in Social Housing Projects was investigated. Initial author observation, analysis of governmental policies and data collected from three case studies allowed to evidence an emergent phenomenon in developing countries such as Chile and in the construction sector experience in general. This phenomenon considers Value as an oscillating concept, which means Value delivered by a particular construction project continuously impacts society in a wide sense, and provides a legacy for future generations. In the same way, Value delivered for particular projects affects in turn those judgments concerning future projects and contribute with the permanent improvement of the construction sector s performance (learning from experience). Consequently, the construction industry contributes to the development of society through the alleviation of environmental & society issues such as drug consumption, social risk, public safety and so forth. Along the time, the decisions and activities of the construction industry have influenced more than a reduced set of customers. Therefore, there is no reasoning against the fact that the human species depends on many sorts of building and infrastructure projects to perform their activities and that the more developed a society or country is, the more such structures are needed. This is an absolute matter of fact. Consequently, building projects as the outcome of build environment could be considered as the physical reflection of our current decisions. They represent major investments in the future delivery, where several human, natural, monetary and technological resources are devoted. Those projects provide a legacy to future generations based on what we have valued today, and how much we care about tomorrow and the stability of our ecosystem. Therefore, the concept of Value in the construction management field should be visualised from a wider perspective towards the consideration of universal environmental & social issues. The consideration of this phenomenon is even more important in developing countries, where opportunities still exist to create a well-balanced built environment that supports society. In an attempt to conceptualise a wider view of Value in the construction industry, different approached to manage Value were investigated. As a result, Lean Thinking arose as a potential philosophy to expand common customer focused Value perspectives. Additionally, different features and multidimensional attributes of the concept of Value were identified. To aid the visualisation of Value in the construction industry, a conceptual model was developed and named the First and Last Value Model F&LVM. According to this model, the delivery of Value spans across two different contexts: First context, which refers to Value delivery to the society (First Value: Environmental & Social issues), and Last context, which deals with Value delivery at project level (Last Value: Production process). This model also considers the interaction between three Value domains: Production & Delivery capacity; Stakeholders perspective; and Social perspective. From this interaction, four central perspectives are included towards a wider visualisation of Value: Technological, economic, environmental and political. Moreover, this model considers Value as an objective, subjective, dynamic, context dependent, relative, and oscillating concept. Finally, the F&LVM was evaluated under the criteria of both researchers and practitioners from Lean Construction, whose potential contributes to a sustainable development. Evaluator s feedback demonstrated that this model contributes to a wider conceptualisation of Value in the construction industry.

A avaliação de empreendimentos do ponto de vista do cliente final tem grande importância no esforço de melhoria da habitação de interesse social, podendo auxiliar na avaliação de resultados, na identificação de erros e acertos frente aos objetivos e ações do projeto. Este tipo de avaliação pode criar oportunidades de aprendizagem sobre os usuários e produtos, contribuindo para aumentar a geração de valor em futuros empreendimentos. No entanto, a diversidade e dinâmica de programas habitacionais e a falta de clareza nos objetivos dos empreendimentos podem dificultar o processo de avaliação. Com freqüência, as avaliações realizadas nos empreendimentos de habitação de interesse social têm como foco os atributos do produto, sem estabelecer uma conexão com os objetivos esperados. Apenas com a clara identificação dos resultados esperados é possível avaliar o sucesso destas empreendimentos, de forma a desenvolver soluções que atendam melhor as necessidades e expectativas dos usuários. O objetivo desta pesquisa foi propor um modelo para estruturar as avaliações de empreendimentos habitacionais de interesse social a partir na percepção dos usuários e adaptável aos diferentes programas habitacionais, com foco na geração de valor. Os conceitos utilizados nesta pesquisa provém principalmente das áreas de marketing e desenvolvimento do produto. O desenvolvimento do modelo partiu da clara identificação do produto habitação de interesse social de forma ampla, sendo adotada uma hierarquia de valor que vincula os atributos às suas conseqüências de uso e aos objetivos esperados. A pesquisa foi dividida em três grandes etapas. A primeira etapa teve como objetivo compreender os programas habitacionais existentes, assim como sobre o processo de desenvolvimento de empreendimentos habitacionais de interesse social e o produto resultante. Na segunda etapa, o modelo de avaliação foi desenvolvido e aprimorado durante os três estudos empíricos nos quais foram avaliados três empreendimentos de programas habitacionais distintos. Na ultima etapa, o modelo desenvolvido foi avaliado, buscando expor as conexões teóricas e contribuições da solução. As principais contribuições da pesquisa são referentes ao modelo de avaliação desenvolvido, que estrutura a avaliação de empreendimentos habitacionais de interesse social, e também ao processo de aplicação do mesmo. / The evaluation of projects from the perspective of the final client is very important for the effort of improving social housing, making it possible to support the assessment of results, and the identification of errors and achievements in relation to project objectives and actions. This type of evaluation may create opportunities for learning about customer and product, and improving value generation in future projects. However, the diversity and dynamics of housing programs and the lack of clarity in project objectives may hinder the evaluating process. Often, the evaluation of social housing projects is focused on product attributes, without establishing a clear connection with the expected objectives. Only by identifying what are the expected results it is possible to assess project success, in order to develop solutions that fulfil the needs and expectations of final users. The aim of this research work is to propose a model for structuring the evaluation of social housing projects focused on value generation, based on the perception of final customers, which is adaptable to different housing programs. The concepts used in this research come from the areas of marketing, and product development. The development of the model starts with the clear identification of the extended social housing product, adopting a value hierarchy that links product attributes to the consequences of its use and intended goals of the project. The research study was divided into three major stages. The first stage aimed to understand existing housing programs, the social housing product development process and the resulting products. In the second stage, the evaluation model was developed and improved in the three empirical studies, in which three projects from different social housing programmes were evaluated. In the final stage, the proposed model was evaluated in order to discuss the theoretical connections and contributions of the solution. The main contributions of this study are concerned with the model itself, which establish a structure for evaluating social housing programs, as well as a process for implementing it.
