**5. Conclusions**

This study represents a valuable opportunity for the field of project managemen<sup>t</sup> and sustainable construction, because it includes the application of the biomimetic methodology to unify its definitions and elements and it allows the circular economy to be innovatively and creatively included in the activities by emulating nature and its self-sustainability. In this way, a defined framework is obtained for all stages of construction, the considerations to be taken within their practices and evaluation of quantitative and qualitative indicators applicable in the phases. Likewise, the exposure of benefits for the environment, investors, designers and contractors through the optimization and automation of the process itself, the costs, risks and success are considered.

In the context of Panama, this study symbolizes a precedent in the field and sensitization of professionals with experience in the country on the relevance of the topic, concepts and components to influence the construction and transform it towards sustainability. In line with this, relevant recommendations can be stated as follows:


Finally, future work could validate the biocircular model within a case study of construction and make improvements, as well as contemplate specific practices within the phase definitions. Among the limitations, we report the summary of the context of the research and the definitions of each phase for the survey distributed to professionals with low background in the subject and its applicability to the different types of existing construction.
