The introduction of digital manufacturing techniques, such as 3D printing applied to concrete material, opens up new perspectives on the way in which buildings are designed. Research on this theme is thriving and there is a high rate of innovation related to concrete. At the same time, the first life-size constructions made from printed concrete are emerging from the ground. This book presents state-of-the-art knowledge on the different printing processes as well as on the concrete material that must adapt to these new manufacturing techniques, such as new hardware and new printers for concrete. The possibilities in terms of architectural design are discussed as well as the pathways that remain to be uncovered. The book also explores the challenges that researchers and companies expect to overcome as they get closer to democratizing this potential revolution that is the digital manufacturing of concrete.

This book explores the latest achievements and design possibilities that 3D printing for construction (DPC) can offer, the alternative materials to natural aggregates or cement and even the 4th dimension that is already starting in this area. DPC materiality is starting to be explored in architecture as a new design language to reach not only outrageous forms but also to leverage the building process and its performance. Like Corbusier explored the concrete potentiality of concrete to release the façade and the plan, 3DPC is allowing to straighten design freedom with building performance. Industry and Scientific research are offering design professionals possibilities to start a new design movement. New paths are also starting to be tracked to reduce even more this building system footprint, stalking alternatives to Portland cement (PC). Today is already possible to build with the soil from the buildings’ ground. Leftovers from various industries are opening possibilities to decrease the PC and natural aggregates rate in printable mortars. From the industry, salt is becoming a possibility to be used in 3DPC. Sugar can ashes are improving the mortar performance reducing adjuvants. Construction and demolition waste can substitute natural aggregates and even offer new textures and color possibilities. Finally, to close this edition, the latest steps on the use of Phase Change Materials in additive manufacturing are collected to raise awareness to the next step of AM, the 4D printing.

As concrete revolutionised construction in the 20th century, digitalisation is transforming the building industry (BI). Process automation and 3D printing (3DP) are commonplace in the industry and our homes. However, due to BI’s scale and complexity, Additive Manufacturing (AM) is in its native stage. Ongoing scientific research has been providing knowledge that will simplify the integration of 3DCP in the market, exploring its materiality, technologies, and design methodologies. This book provides an overview of the latest research achievements of the design possibilities that 3DP for construction (3DC) can offer in the various fields of construction, particularly architecture and engineering.

Modelled on the concept of Industry 4.0, the idea of Construction 4.0 is based on a confluence of trends and technologies that promise to reshape the way built environment assets are designed, constructed, and operated. With the pervasive use of Building Information Modelling (BIM), lean principles, digital technologies, and offsite construction, the industry is at the cusp of this transformation. The critical challenge is the fragmented state of teaching, research, and professional practice in the built environment sector. This handbook aims to overcome this fragmentation by describing Construction 4.0 in the context of its current state, emerging trends and technologies, and the people and process issues that surround the coming transformation. Construction 4.0 is a framework that is a confluence and convergence of the following broad themes discussed in this book: Industrial production (prefabrication, 3D printing and assembly, offsite manufacture) Cyber-physical systems (actuators, sensors, IoT, robots, cobots, drones) Digital and computing technologies (BIM, video and laser scanning, AI and cloud computing, big data and data analytics, reality capture, Blockchain, simulation, augmented reality, data standards and interoperability, and vertical and horizontal integration) The aim of this handbook is to describe the Construction 4.0 framework and consequently highlight the resultant processes and practices that allow us to plan, design, deliver, and operate built environment assets more effectively and efficiently by focusing on the physical-to-digital transformation and then digital-to-physical transformation. This book is essential reading for all built environment and AEC stakeholders who need to get to grips with the technological transformations currently shaping their industry, research, and teaching.

The book provides a comprehensive overview of the up-to-date, practical knowledge in highway engineering. It highlights the latest industry standards and policies, such as the best-value award algorithms in the selection of design-builders, the urban logistics guidelines for the efficiency of goods distribution, and the adoption of a uniform increased service load based on vehicle characteristics. The book explores also recent design and construction methods, such as building information modeling, the use of 3D printing, the performance evaluation of road pavements, and the risk matrices as environmental management tools. The latest techniques for traffic evaluation and road safety are also presented, such as the evaluation of loopholes, the optimization of fast lanes and lane-keeping systems, and the use of machine learning algorithms. This book helps readers maximize the effectiveness of different aspects of highway engineering. This professional book as a credible source and a valuable reference can be very applicable and useful for all professors, researchers, engineers, practicing professionals, trainee practitioners, students, and others interested in highway projects.
