To reduce embodied emissions and waste in renovation projects, new resource efficient and low waste construction processes are needed. One possible solution to reduce waste at the construction can be made-to-order (MTO) customisation of standard products that are delivered in the right size and quantity. A key construction process in renovation pro...

Previous studies have applied the Work Sampling (WS) technique in different job sites to determine how workers employ their time in relation to a taxonomy of various work activities. However, no other significant contribution has been discussed for including location information of the work activities. This study added a geographic location to each...
Conference Paper
Full-text available
The Work Sampling (WS) technique has been used in the construction industry since the 1960s to understand how workers spend their time. However, the WS categories have exhibited variation throughout history due to interpretation and application discrepancies. This lack of consensus on what represents Value-Adding-Work (VAW) and Non-Value-Adding-Wor...

Construction can be considered a socio-technical system, which is challenging to model due to the many agents interacting either in a managed way or autonomously. Therefore, cause and effect models are hard to validate, and a traditional correlation approach is insufficient. In this study, the method of robustness testing was applied to test the ef...

This study is part of an ongoing research project aiming to develop a method for understanding workers’ efficiency (workers’ time spent in value-adding activities) by measuring new indexes, such as workers’ travelled distances and workers’ locations collected by smartwatches. To achieve the objective of the study, a Design Science Research (DSR) st...

The European Green Deal’s Renovation Wave aims to renovate 35 million energy-inefficient buildings to reduce carbon dioxide (CO2) emissions by at least 55% by 2030. Historically, efforts to reduce CO2 emissions focused on Operational Energy (OE) of the finished buildings. However, in recent years the Embodied Energy (EE) of the building’s construct...

The use of games in engineering teaching is common practice in classes with lecturers all over the world. However, due to the COVID-19 pandemic, undergraduate civil engineering education became virtual and remote. In this context, many games traditionally played in person among students have undergone adaptations to the digital environment. The gam...

RESUMO Esta pesquisa propõe a aplicação do princípio da filosofia da construção enxuta de minimizar ou eliminar todas as atividades que não agregam valor a partir da redução das atividades de transporte. Para tal, este trabalho avalia num estudo empírico a utilidade da técnica de optimização com base em Algoritmos Genéticos (AG) para reduzir distân...

Construction 4.0 is the adoption and adaptation of the Industry 4.0 framework for the construction sector. Industry 4.0 promises to revolutionize how ‘things’ are made by using physical and digital technologies in an integrated manner. Similarly, the authors envision that the Construction 4.0 framework can fundamentally change the way that assets a...

O presente estudo avaliou o potencial de captação de águas pluviais pelas fachadas de edificações. Para tal, foi estudado um empreendimento residencial vertical de quatro pavimentos com uma área de 900 m² de fachada. O cálculo dos valores do Volume Captado (diário e mensal), bem como da Taxa de Atendimento (mensal e diária) foram estudados para os...

The Military Firefighters Corps of Bahia in 2015 established the Technical Instruction n°43 which regulates standards and measures of security against fire and panic in buildings, structures, and risk areas. According to this Technical Instruction is mandatory to build, adapt and reform buildings according to the legal requirements of the Decree La...

The use of 4D Building Information Models (BIM) for planning construction site logistics has increased in recent years. However, most 4D BIM studies have focused on transformation tasks, neglecting flow activities. Hence, the objective of this paper is to evaluate the use of 4D models for flow simulation at operational level, aiming to reduce trans...

This paper presents the results of an empirical study carried out in a residential building project in the Northeast of Brazil, which involved the use of the reinforced concrete walls structure as main construction technology. The main goal of this study was measuring the time waste in transportation activities in the construction technology used....

Logistical planning is still a neglected step, despite it establishes conditions for the effectiveness of the production process. Anticipation in the decision-making process and improvements in logistic can provide competitive advantage for construction companies. This study focuses on the evaluation of the potential of improvements that the simula...

RESUMO A necessidade de um planejamento logístico envolve a redução das perdas nas atividades de transporte, ocasionadas, entre outros motivos, por transportes excessivos e problemas no acesso e na mobilidade dentro do canteiro de obras. Os transportes excessivos estão intrinsecamente relacionados à escolha de um layout de canteiro deficiente. Muit...

Supply chain management in construction projects has been previously studied. However, the material logistics and layout planning on construction sites still has room for investigations. An improvement of the visibility of flows at the jobsite connecting the analysis of schedule and physical flows within 4D BIM environment is suggested. The objecti...

Planning the logistic operations and the construction site layout is extremely important to avoid waiting time, double handling, transportation wastes and workflow conflict. Therefore, workspace management can support the Lean thinking through minimization or even completely eliminating the transportation, inventory and motion tasks, which are all...

Transportation is a waste category that has not been much explored in the literature on construction management. Moreover, the existing studies about it have focused mostly on its impacts and not on the causes. This paper aims to present the results of a second implementation of a method in order to identify, measure and characterize the transporta...
