Understanding the Interaction Between Virtual Design, Construction and Lean Construction

Actualmente, los proyectos de edificaciones que se vienen ejecutando generalmente no cuentan con una ingeniería definida al inicio de la etapa de construcción. Esto genera que los proyectos tengan numerosas indefiniciones en su inicio. A consecuencia de ello, las consultas, las órdenes de cambio, y definiciones se dan en mayor cantidad en la etapa de ejecución aumentando el esfuerzo y por lo tanto incrementando el plazo contractual en la solución de cualquier retrabajo. Las metodologías tradicionales, no colaborativas, suelen tener como común denominador, la gran cantidad de solicitudes de información durante la construcción. Esta situación sumada a de un flujo lento de respuesta a las consultas realizadas en campo puede resultar perjudicial para la entrega oportuna del proyecto. Esta metodología VDC se basa en “construir” dos veces, es decir construir previamente la edificación en un modelo virtual con todas las especialidades consolidadas y compatibilizadas para una vez teniendo el modelo liberado y libre de indefiniciones, se proceda con la construcción real. Esta metodología, busca la reducción de los recursos innecesarios y la disminución de la variabilidad a través del trabajo colaborativo mediante las sesiones ICE en el uso conjunto de herramientas tecnológicas (BIM) y filosofías Lean. La presente tesis demuestra que, teniendo un modelo integrado en la etapa de diseño y acompañado de un equipo colaborativo en sesiones ICE, es posible trasladar los esfuerzos de la etapa de construcción a la etapa de diseño y de esta manera reducir el tiempo de ejecución de los proyectos.

The construction industry is prone to major safety hazards owing to the complex and onsite nature of construction projects. Hence, construction researchers have been pursuing concepts, methods, and tools using advancing technologies to improve construction safety management. Subsequently, the rapid digitization of construction work practices is providing opportunities to improve construction safety. Research has revealed that construction safety management practices can benefit from the applications of virtual design construction technologies (VDC), such as building information modeling (BIM), virtual reality (VR), augmented reality (AR), geographic information systems (GIS), and gaming technology. This study comprehensively reviews 191 research articles, published between 2010 and 2019, focusing on providing an overview of the implementation and application of VDC technologies for improving construction safety. The objective of this review is to critically collect and analyze applications of VDC technologies and present a holistic view of the features and functions of VDC technologies that can impact jobsite safety improvement in the construction industry. The review showed that VDC technologies can substantially improve construction safety. Emerging digital technologies, such as BIM, VR, AR, GIS, and gaming technologies can transform the traditional document-oriented safety procedures into digitalized safety practices allowing safety managers to visualize and analysis construction sites virtually to devise proactive safety measures and effective safety trainings. This study also highlights challenges such as research gaps regarding these digital tools that are currently impeding their widespread use in construction safety.

Master Builders

Effective substation management should include engineering and construction costs. While the construction process has to be methodically planned and sequenced to achieve optimized construction costs, substation designers play a vital role for delivering cost-efficient substations. Integrated design and construction has been proposed as a way to achieve effective project management, which historically viewed, was a responsibility of a “master builder”, thus causing Contractors to identify themselves as “master builders”. As EPC is a highly competitive arena, Contractors are looking for ways to differentiate themselves from their competitors. Some are turning to 3D technologies, while others turn to the design-construction integration. Virtual Master Builder (VMB) supports both 3D technologies and the design-construction integration. Due to a global shortage of worldwide available expertise, Contractors turn to education and training of their employees. While education aims at providing basic skills, training aims to provide the skill necessary to do the job. This paper examines these basic skills as a part of personal mastery before defining organizational learning as a key organizational competence. Physical Virtuality realm is seen as a fruitful ground for staging of memorable and transformational experiences leading towards achieving “accelerated learning”, and especially 4D models as representations of a “space-time” environment. The project case of Skopje 4 SS 380/110 kV rehabilitation is given as an example of 4D models usage. Project Engineering is seen as a middle ground between engineering and management in order to achieve goals of effective substation management and cost-efficient substation solutions. Project teams are seen as Virtual Design and Construction (VDC) users to achieve these goals.

Design Construction

With the advancement of digital design practices in the global construction industry, different aspects related to the project lifecycle are extracting their benefits, including making improvements in safety. The objective of this paper is to ascertain the awareness of these technologies, their potential, and any barriers related to the use of different virtual design construction (VDC) tools, such as building information modeling, virtual reality, augmented reality, and geographic information systems, to improve job-site safety in Gulf Cooperation Council (GCC) countries. The paper presents an overview of the GCC construction industry and highlights current safety management practices and problems in the region. The potential of VDC tools for improving job-site safety is discussed and presented. The study has used a questionnaire survey to identify the drivers and barriers of using VDC tools in improving job-site safety management in the GCC region. The results indicated that “designing emergency and evacuation plans” and “fall-hazard prevention strategies” are the two best safety applications of these tools if used proactively. Similarly, “lack of knowledge about return on investment for VDC tools” was considered as the predominant barrier, preventing stakeholders from using these technologies to improve construction safety. These results will help the GCC construction industry to build a strategy for the digitalization of proactive constructability analysis techniques for improving job-site safety. Overall, due to the multilingual dynamics of this region, it is recommended that VDC tools should become more prevalent so that the transfer of safety information and hazard prevention becomes easier, mitigating safety risks.

Design Construction

In the new global economy, Lean Construction has become an effective way to design construction systems, which aims at reducing all forms of waste and creating the maximum of value for the customer. However, previous studies have reported that there are various implementation approaches, and most construction practitioners have applied this management philosophy according to their own understanding of Lean Construction principles. The main aim of this study is to develop a conceptual model for a successful deployment of lean construction. In this paper, an original generic model has been proposed based on a rigorous analysis of six relevant Lean Construction models that have been designed, validated, and tested in several countries (USA, UK, Malaysia, Germany, and Brazil). The findings of this work show that there are nine main Lean Construction principles and which are: customer focus, supply, continuous improvement, waste elimination, people involvement, planning and scheduling, quality, standardization, and transparency. Moreover, these principles have been divided into 33 sub-principles based on an extensive literature review of reliable documents (research papers, review papers, books, conference papers, and thesis) that have been published between 1992 and 2017.
