The construction industry continues to experience productivity rates that lag behind other industries. Additionally, an increasingly competitive market and a decreasing skilled labor pool are challenging construction firms. Prefabrication and offsite modular construction techniques offer alternatives to traditional site-built construction methods that have the potential to provide improved productivity as well as other added benefits. Prefabrication methods, applied effectively, offer results that produce value to the project team. Such value includes improved productivity and efficiency in construction operations, reduced project costs, reduced schedule durations, and improved safety, increased levels of quality and improved sustainability and waste reduction. Currently the implementation of prefabrication and offsite construction techniques on the construction project remains subjective and unstandardized. The aim of this research is to develop a framework that will assist the project team to make decisions regarding the use of prefabrication and modular construction based on factors that have proven to be the most successful in implementing modern methods of construction. The concentration is on emphasizing the use of Building Information Modeling and Lean Construction methods as catalysts to maximize the effectiveness of the use of modular offsite construction. This research is primarily toward the use of prefabrication and modular construction methods for vertical construction and should prove valuable for all project players including Owners, Designers and Constructors. The development of this framework utilizes information compiled through interviews and case studies to develop a proposed framework for implementing prefabrication and off-site modular construction techniques at the project level. The framework will be validated in the future using a Delphi survey to qualitatively generate quantified data on the best methods to implement prefabrication and offsite construction techniques.

The productivity of the construction sector in Spain is very low, as compared to other economic sectors, as with other countries in our environment. It takes us to a deep reflection on whether we are doing things right and what improvements can we introduce to increase production. These improvements must necessarily be technological and methodological, since there is a good training of the equipment both at the managerial level, as well as at the technical and in most of the labour levels, it is to exploit the full potential of new IT tools, especially Building Information Modelling (BIM) and the new methodologies that, from the industry, look for greater efficiency of the process and the elimination of all type of losses, like Lean Construction. A change of mentality, necessary to rethink the way of work in which we have been working for so many centuries, as the only possible paradigm, to replace confrontation as a way of producing construction through collaboration between all the agents involved in the work. We will speak in this article about Integrated Project Delivery (IPD), as one of the Lean methodologies that enable a profound improvement, we will see its definition, its essential components, and how it application can positively influence the construction process in Spain as it has already demonstrated in others.ResumenLa productividad del sector de la construcción en España es muy baja, tanto comparativamente con otros sectores económicos, como con la de otros países de nuestro entorno. Se hace necesaria una profunda reflexión sobre si estamos haciendo bien las cosas y qué mejoras podemos introducir para incrementar la producción. Estas mejoras han de ser necesariamente tecnológicas y metodológicas, ya que existe una buena capacitación de los equipos tanto a nivel directivo, como en la escala técnica y en muchos casos en la laboral, es decir, se trata de aprovechar todo el potencial de las nuevas herramientas informáticas, especialmente Building Information Modeling (BIM) y de las nuevas metodologías que, provenientes de la industria, buscan una mayor eficacia del proceso y la eliminación de todo tipo de pérdidas, como Lean Construction. Un cambio de mentalidad necesario, que pasa por replantearnos la forma de trabajo en la que llevamos tantos siglos empeñados, como único paradigma posible, sustituir el enfrentamiento, como forma de producir la construcción, por la colaboración entre todos los agentes intervinientes en la obra. Hablaremos en este artículo de los Métodos Colaborativos en construcción, que en inglés se han denominado Integrated Project Delivery (IPD), como una de las metodologías Lean que posibilitan una profunda mejora, veremos cuál es su definición, componentes esenciales, y cómo su aplicación puede incidir positivamente en el proceso constructivo de nuestro país al igual que ya lo ha demostrado en otros.

Architecture, engineering, and construction industries maintain a long standing desire to enhance design communication through various forms of 3D CAD modeling. In spite the introduction of Building Information Modeling (BIM), designers and builders expect varying amounts of communication loss once construction has started due to indirect construction techniques or hand based methods to manufacture buildings. This is especially true for houses and small structures, buildings that makeup the core of villages and suburbs. Unfortunately, paper documentation and reading 3D CAD models on screen continue the trend of indirect production defined in most manufacturing industries as error. The emerging application of CAD/CAM within design and construction industries provides hope for elevated communication between design and building. With CAD/CAM, it is possible to manufacture buildings of all types and sizes directly from CAD files similar to mass produced artifacts, thus reducing complexity in communication between parties. This chapter is presentation of one process of direct manufacturing from CAD and the emerging possibilities for small building production using digital fabrication. The chapter will focus on houses to illustrate the potential of direct manufacturing of buildings from CAD data.

Building information modeling (BIM) implementation has been mandated in building projects in Singapore, but a wider adoption is still desired. This study aims to investigate the factors influencing BIM diffusion and examine how the factors influence firms with different project roles, firm sizes, and BIM implementation experience. The results of a pilot study, a questionnaire survey with 89 professionals, and five post-survey interviews showed that hindrances related to inadequate multi-party collaboration (whether formal or informal), conservative mindset, limited skills, costly infrastructure and training, and multi-discipline model integration were the most influential, whereas drivers associated with project leadership team’s strategic consensus, multi-disciplinary design coordination, training, and government regulations were top-ranked. Subgroup analyses between pairs of firms with different characteristics revealed that while construction firms and less experienced stakeholders tended to underestimate BIM implementation difficulties, small-medium contractors might underestimate relevant benefits. The findings and managerial recommendations help different types of firms prioritize resources to overcome hindrances, seize opportunities (such as gaining a competitive edge from BIM practical experience), and obtain support from workers executing BIM daily. With major stakeholders’ recognition and implementation, BIM can be successfully diffused in building projects and firms. The Singapore government and other countries can refer to this study when further issuing BIM diffusion policies.

Schedule Performance

In the recent years, owners and construction management companies have shown an increasingly more interest in adopting approaches that result in enhanced quality and less risks, conflicts, and wastes on their projects despite potentially higher initial cost. Implementing advanced technology trends and incorporating more integrated methods of delivering projects have proven to be highly value-adding and forward-thinking approaches. The objective of this research was to evaluate the effectiveness of and the synergy between three of such trending concepts in the construction industry, namely, integrated project delivery (IPD), lean principles, and building information modeling (BIM) in terms of cost and schedule performance measures. Data analysis was conducted on 72 vertical projects through interviews and study of the published articles, reports, and case studies. Qualitative analysis was performed through grounded theory while quantitative analysis was implemented using univariate and multivariate analysis of variance tests on schedule performance and cost performance. Results of the grounded theory analysis summarize six crucial characteristics required for an effective coordination between IPD, lean construction, and BIM. Statistical analysis on different combination of these three components revealed considerable effectiveness in terms of schedule performance while the effect on cost performance was not as much significant. This study contributes to the body of knowledge and practice in the field of construction by demonstrating the cost and schedule benefits realized through the use of IPD, lean construction, and BIM and identifying their collective conceptual advantages.

Lean Construction is one of the methods used to improve control over construction projects by eliminating waste in time and materials. Lean Construction is an adaptation from the Lean Manufacturing principles to the construction industry. The purpose of this article was to review the case studies published in 2018 in the Inspec database to find out where Lean is being implemented and how. The article approach by setting the search criteria first and then inspect the result to find the non-related results and eliminate it. After that, the article was reviewed and summarized. The article verifies each article finding; however Lean Construction and Building Information Modeling (BIM) are relatively new for the construction industry and they still need more time to be adopted widely and to be applied on a lower-cost budget. However, the discussed cases show a promising future for these technologies.
