Considering the gradual move into the information age, digital technologies have become the new trend in different industries ranging from agriculture, manufacturing, transportation and banking, among others. The construction industry has also evolved progressively since the last decade to explore and adopt digital transformation considering the immense contribution it has towards productivity. More so, the need to combat global warming has compelled experts to begin to seek new technologies in achieving the green effect. This has led experts and researchers in the industry to seek how digital technologies can help to achieve sustainability and further functional construction. There has been a huge gap as to maximising the impact of digital transformation as many organisations in the industry are still struggling to successfully adopt and implement digital construction. This chapter will help to fill this gap and provide clear insight into how digital can help further sustainable construction.

In terms of having the general idea of what the whole book entails, the first chapter gave an insight into all the chapters and what details each chapter holds. This chapter began with an introduction of the book title in relation to the construction industry and sustainable practice in a collaborative manner. In addition, sustainable infrastructure management (SIM) was discussed in relation to construction Industry 4.0 and the management qualities of the technologies incorporated into construction activities. The objective of the book gave the need for SIM in construction with the view of achieving sustainable practices beneficial to both the client and the construction professional.

Quantum computer design is a registration that utilises quantum-mechanical wonder, like superposition and entrapment, used to arrange the assets of a quantum computer. A deliberate layered system can be planned to handle the difficulties, which emerge during the advancement of a quantum figuring. The plan usefulness is isolated into layers where the subsystems are planned in such a manner with the goal that it can investigate the issues freely and measures better between the layers bringing about a superior arrangement. Right now, all adaptable quantum figuring innovations are recommendations and critical advances in assembling necessities needed to carry them to the real world. By and by, a few recommendations have less cumbersome innovative obstacles before them than others. Even though its applications are somewhat limited in the construction industry, steps have been taken towards its implementation across the industry as well as other industries.

Today, sustainability is considered a high priority; and it is on the agenda for major corporations. It has experienced an increase due to the demands of the customers, thereby pressuring corporations to act in more sustainable ways to stay relevant and competitive. One industry that is experiencing an increased request to act sustainably is the construction industry. The construction industry differs quite a lot from other industries since it is project-based and built on temporary relationships. Subcontractors are temporarily engaged in the projects, often by a main contractor, to perform tasks in which they are specialised. The subcontractors additionally engage their respective subcontractors. This makes it harder to control and ensure that all involved actors are acting sustainably due to the multiple tiers of contractors and the complex nature of the projects. A technology that recently has had the attention of construction professionals is blockchain technology, which is built on smart contracts. It can be described as a shared, distributed ledger technology, which was created as an enabler for the cryptocurrency Bitcoin. The technology has, in recent years, been widely discussed as a potential business enhancer. It can, for example, provide immutable record-keeping, enables the usage of smart contracts and enhance transparency within the network, which is deemed valuable to the construction industry's push towards sustainability. The smart contracts technology has the potential to disrupt current business practices and decrease the required amounts of trust needed in business relationships.

Mobile computing enables mobile devices to boost restricted resources, and this further includes processing, storage space and battery freedom with the help of cloud facilities. Cloud computing (CC) enables users to obtain admission to energy from another location, providing movement, and enabling common data admission. This chapter is tailored towards responding to a variety of the main challenges of the construction industry with the help of utilising mobile cloud solutions and services. The main benefits of embracing CC largely centred on resources which are expressed in cost reduction, system mobility, system flexibility and system maintenance, while the threats are information protection, individual accessibility, governing conformity, data location, accessibility and also disaster recuperation. This chapter provided necessary solutions to the main threats in the construction industry in terms of design, materials, finance, management and knowledge with the application of mobile cloud computing.

Ecological economics is a multidisciplinary endeavour to connect the social sciences and nature in general. It also connects aspects of ecology and economics to a particular understanding. The created concept centred on the mission to acquire a more advanced albeit better scientific understanding of the complex interconnections between humans, animals and the rest of nature. This is driven towards utilising the obtained knowledge to establish policies that will lead to a more environmentally sustainable world, with a fair resource distribution (both across human groups and generations, as well as between humans, the environment and other species), and also efficiently allocates limited resources such as ‘natural’ and ‘social’ capital. This practice necessitates the development of new methodologies that are comprehensive, adaptive, integrative, multi-scale, pluralistic and evolutionary, while also acknowledging the enormous uncertainties involved.
