BIM Use Assessment (BUA) Tool for Characterizing the Application Levels of BIM Uses for the Planning and Design of Construction Projects

The evaluation of BIM capabilities and repeatability enables a company or project to identify its current status and how to improve continuously; this evaluation can be performed with BIM maturity models. However, these maturity models can measure the BIM state but not specifically the application of BIM uses. Likewise, in interorganizational project teams with a diversity of factors from various companies, it is possible to evaluate the capacity at a specified time with specified factors, but it is not possible to evaluate the repeatability unless the client always works with the same project teams. Therefore, despite the existence of various BIM uses in the literature, there is no instrument to evaluate the level of implementation of them in construction projects. This research proposes a BIM Use Assessment (BUA) tool for characterizing the levels of application of the BIM uses in the planning and design phases of building projects. The research methodology was organized into three stages: (1) identification, selection, and definition of BIM uses; (2) proposal of the BUA tool for characterizing the level of BIM use application; and (3) validation of the BUA tool. The tool was validated using 25 construction projects, where high reliability and concordance were observed; hence, the BUA tool complies with the consistency and concordance analysis for assessing uses in the design and planning phases of construction projects. The assessment will enable self‐diagnosis, stakeholder qualification/selection, and industry benchmarking.
Factors generating schedule delays and cost overruns in construction projects
(2021) Adriana Gómez Cabrera; José Luis Ponz‐Tienda; Eugenio Pellicer; Amalia Sanz
Delays and cost escalations in construction projects are problems that have been approached by many researchers through time, developing a significant body of literature. This paper developed a literature review to examine 30 research papers published since 1988 in the Web of Science database to identify the main factors causing these deviations. The results show that articles are covering different continents, decades, and project types (infrastructure-building). There are more articles regarding time deviation, and most of the articles belong to Asia and Africa. A list of 73 factors reported in the papers and also the top 10 most common factors. Factors were grouped considering the project life cycle stages, listing those related to Planning/Design (17), and Construction (46) and ten additional factors related to external causes were included.
Plataforma de datos abiertos de contratacion de obras públicas del gobierno colombiano
(2021) Adriana Gómez Cabrera; José Luis Ponz‐Tienda; Eugenio Pellicer; Andrés Torres
In recent years, transparency in public procurement has increased considerably as a strategy to curb corruption and implement best practices by governments. Since 2007, Colombia has been implementing different approaches in this sense, which have been evaluated by international bodies with outstanding results. The country's open data platform is mandatory, and all public entities must publish the processes carried out there. This paper presents the “Sistema Electrónico de Contratación Pública de Colombia – SECOP” with emphasis on the construction phase of infrastructure projects, which contains information on all stages of construction projects. There are examples of data and analysis that can be made from them.
