Lean Methods

The Kingdom of Saudi Arabia (KSA) has witnessed a huge increase in construction during the last two decades. However, many projects experienced time delays, cost overruns and the generation of massive amounts of waste. To address these challenges, lean construction has been introduced into the Saudi construction industry; however, it is still in its infancy. This study therefore investigates the current state of lean construction implementation in the construction industry in the KSA. The objectives are to identify: the types of construction waste, level of use of tools that support the implementation of lean construction, stages of application of lean methods, and the benefits of lean construction. To achieve these objectives, a structured questionnaire survey of 282 construction professionals was carried out. After the analysis of the collected data using mean score and Anova test, the following conclusions were made.  In the construction industry in the KSA, waiting is the most common type of waste, while Computer Aided Design (CAD) is the conventional tool supporting the implementation of lean construction. Furthermore, the data suggests that lean construction is most commonly used in the construction stage of projects while customer satisfaction is the main benefit derived from lean construction practices. This study concludes that the level of implementation of lean construction in the KSA construction industry is increasing. The results will help benchmark the current state of lean construction implementation, which will enable the construction industry to identify strategies to implement lean construction in Saudi Arabia in accordance with their needs and project goals, to achieve better productivity.

Toma De Decisiones

El objeto de este trabajo fue establecer propuestas de mejoramiento al proceso de planeación de tiempos y costos en la etapa de cimentación de un edificio, a partir de la integración de herramientas como simulación de eventos discretos, programación con líneas de balance y metodologías Building Information Modeling - BIM. A partir de mediciones en campo se levantó información para la elaboración de un modelo de simulación de eventos discretos que imitara el proceso constructivo real. Se propusieron y modelaron alternativas de mejora, a partir de los principios de la filosofía Lean Construction y la programación de líneas de balance encontrando reducciones en tiempo y costo. También se realizó la animación virtual de las alternativas a partir de metodologías BIM. Se concluye que la integración de las herramientas utilizadas es de gran utilidad en la planeación y toma de decisiones en un proyecto civil.

O setor da construção civil, em constante desenvolvimento de ferramentas de gerência, cada vez mais aplica conceitos antes somente utilizados na indústria. Uma das ferramentas há muito tempo utilizada nas fábricas, o sistema kanban, agora se mostra aplicado em uma obra de construção civil. Essa aplicação se dá no sistema de distribuição vertical do guincho decarga de uma edificação de vinte e três pavimentos. A empresa onde está sendo utilizado o sistema kanban já tem tradição em utilizar inovações tecnológicas e em implantar conceitos da Lean Construction. Vários outros trabalhos já foram publicados em congressos mostrando as aplicações de diversas técnicas de planejamento e controle da produção nos seuscanteiros de obra.
