    In construction investments, the total cost of investment is a quantitative estimate of the probable cost in which it is difficult to minimize the gaps associated with risk factors. The objective of the research is to estimate the gaps associated with risk factors in the total cost to reduce the aforementioned gaps. As results, a complex process was obtained in instrumental matters, from the approach of probabilistic scenarios that entails the need to decide the way in which probabilities are going to be expressed. The conclusions were given from decision-making perspectives of the probabilities of gaps occurring through sensitivity analysis that studies the impact they have on a given dependent variable and the variations that this causes in any of the independent variables that make up the problem studied. The estimation of the size and importance of the magnitude of the risk was also determined, for which the level and degree of sensitivity of the impact of the breaches was set. In this research, the methods of scientific research were used, such as modelling; measurement; and the Monte Carlo Simulator [SMC].

    The affectations caused by extreme events of natural origin such as droughts and floods in traditional homes in the province of Gran Chaco, in Bolivia, are frequent. These aspects compromise the habitat of the populations that occupy them, as is the case of the original Weenhayek people, as an alternative for the improvement of the human habitat of this town. Through theoretical and empirical methods, five variables used for the development of the adaptation model were determined, from the bases of planned adaptation as a component of urban-territorial resilience, in search of an improvement of socio-environmental systems in the face of the effects of climate change, exemplified in the Weenhayek native people. The model establishes the improvements of traditional dwellings, from a current trend of deterioration to one of preservation, conservation and growth in the Weenhayek culture, through various features, such as: Respects the cultural design of the house that integrates local patterns of the environment, ecosystem and contemporary construction elements without affecting its image, the materials and construction techniques used are of a traditional nature, but with contemporary elements that improve their application, durability, stability, as an articulated construction system, commits governments in all instances to the technical-constructive study of the rural areas of the human settlements of the Weenhayek people, and establishes a starting point towards new studies focused on native peoples.

    <jats:p>Resumen La concepción ambiental para los recursos construidos de valor patrimonial permitió adaptar e integrar teorías, modelos y sistemas empleados universalmente en la gestión ambiental, urbana y patrimonial, en un modelo conceptual para la gestión ambiental urbana de los recursos construidos de valor patrimonial. Derivado este, se concibió y desarrolló una metodología que incorpora los enfoques ecosistémicos, estratégicos y participativos, así como describe un proceso que transita por tres etapas: valoración-planificación, conservación-implementación y monitoreo-control y un conjunto de herramientas que contribuyó a conservarlos, y enriquecer dicho ambiente de una forma equilibrada, territorialmente factible y equitativa para la sociedad. Su aplicación en tres pueblos cubanos, posibilitó generar cambios e impactos favorables en el desarrollo económico local y en la calidad de su ambiente, propiciando mejores condiciones de vida; a través de ofertas de servicios, empleos, espacios sociales de uso colectivo, entre otros componentes que han ayudado al desarrollo local respectivamente. Es por ello que el objetivo del presente artículo es socializar los resultados de las contribuciones de la gestión ambiental urbana, desde el tratamiento como recurso ambiental a los valores del patrimonio construido, mediante un proceso metodológico que ayuda a su conservación y al desarrollo local.</jats:p>

    Hurricanes are one of the most significant causes of human and material losses in the Caribbean region. These events have demonstrated their devastating impact on housing and infrastructure. The assessment of the vulnerability of buildings with light roofs, at the initial design stage, is considered to be a fundamental step in the mitigation of these damages and losses. This paper presents the introduction of an indicator-based vulnerability assessment in an effort to mitigate these damages in advance. This indicator facilitates the design team's decision to select the appropriate light roof alternative subject to strong winds at the conceptual stage of the process. The indicators that contribute to the conceptual assessment of vulnerability were identified based on a comprehensive review of the literature and numerical simulations of the risk scenarios using CFD/FEM software’s. The ranking of indicator weights was determined by the Kano method according to experts' opinions. A desktop application has been developed for the assessment of the vulnerability of light roof variants for buildings at the conceptual design stage. The results reported in a case study demonstrate the viability of the desktop application based on the vulnerability indicator to assist decision making in the conceptual design stage.
