The Architecture, Engineering and Construction (AEC) Industry in Colombia is starting to implement Building Information Modeling (BIM) in their projects but in a much unorganized way. This issue could be attributed to a lack of unique and public BIM standards and guidelines for the implementation along with the inexistent support to the industry from the Government on the road to implementation. The BIM Execution Plan (BEP) is a procedural process that outlines the project’s overall vision with implementation details for the project team to follow throughout the project. In this study, the authors reviewed 20 BEPs searching for the presence of some identified and analyzed subcomponents to determine which documents were more robust. By performing a 27-question survey to understand how different BIM tools affect a BIM implementation, we investigated about the experience of some companies in the industry with five in depth interviews conducted to AEC Colombian professionals. Finally, a presentation of a BEP template that uses the analyzed documents and the identified problems in the interviews, along with an explanation of how was the use of information obtained to develop the new BEP template. Conclusions and recommendations are provided to enhance the BIM implementation in Colombia along with the template and the support files that can also help to develop and integrate future BIM process tools methodologies. Resumen La industria de Arquitectura, Ingeniería y Construcción (AEC) en Colombia está empezando a implementar Building Information Modeling (BIM) en sus proyectos, pero de una manera muy desorganizada. Este problema podría atribuirse a la falta de normas y pautas de carácter unificado y público para la implementación de BIM junto con el apoyo inexistente a la industria por parte del gobierno en el camino hacia dicha implementación. El Plan de ejecución BIM (BEP) es un procedimiento enmarcado en procesos BIM que describe la visión general del proyecto con detalles de implementación para que el equipo siga a lo largo del ciclo de vida del proyecto. En este estudio, los autores revisaron 20 BEPs en busca de la presencia de algunos subcomponentes identificados y analizados para determinar qué documentos eran más robustos. Al realizar una encuesta de 27 preguntas para comprender cómo diferentes herramientas BIM afectan su implementación, investigamos sobre la experiencia de algunas empresas en la industria con cinco entrevistas a profundidad realizadas a profesionales colombianos de AEC. Finalmente, hay una presentación de una plantilla de BEP que se basa en los análisis de los resultados y los problemas identificados en las entrevistas, junto con una explicación de cómo se utilizó la información obtenida para desarrollar la nueva plantilla de BEP. Se presentan conclusiones y recomendaciones para mejorar la implementación de BIM en Colombia, además de una plantilla y los archivos de soporte para que cada empresa que desee desarrollar su propio BEP pueda revisar la información presentada en este documento.

ABSTRACT:The conservation of built heritage is becoming increasingly important, and may even be an obligation for future generations. Techniques must therefore be developed to help document heritage and thus improve knowledge and conservation. The terrestrial laser scanning technique allows a massive capture of points of an object. Among its main applications are to obtain geometries of historic buildings and monuments, allowing the documentation of their heritage. But this technique also facilitates other very important information for the conservation of the monument in question from the same data set: the damage it presents. We can, therefore, also document the geometry of the object by making a survey of the damage it presents at the moment of data collection. The cracks and their layout and trajectory can be observed, allowing measurements to be made to assess necessary conservation measures. Given that the apertures of the same crack at different points in historical structures often vary by several centimeters, it is also important to know the extent of the damage along its entire path, and whether there is any relative motion between the two sides of the crack. This communication presents the application of laser scanning in the Alcántara Bridge and Coria Cathedral, both in the province of Cáceres (Spain). It outlines the criteria used for scanning both monuments: selection of placements, recording technique, errors between placements and the elimination of residual points. Once the mesh had been obtained, the information on the damage presented by these monuments was analysed, describing, characterizing and contrasting them with data taken in the field. * Corresponding author. This is useful to know for communication with the appropriate person in cases with more than one author.

There are many methods of multicriteria decision analysis (MCDA), each one with properties and benefits. In the Architecture, Engineering, and Construction (AEC) sector most of the time, the decision-making involve different interest of the stakeholders of the projects, must of the times applying methods with the focus on the result. This paper presents a case study of a new University's facility construction that compares the traditional decision-making approach used in the design-bid-build procurement method of AEC industry in Colombia with an MCDA approach. Choosing By Advantages (CBA) has been used to analyse the reasons that could help explain why the subcontractor of a project construction was not meeting the client's expectations during project execution. Results include a discussion of main differences between these decision methods, the main difference is that in traditional decision-making approach the main criterion was cost while in the CBA was value. Consequently, the method's results were different for the alternatives.
