Also, by eliminating the need for intermediaries or third parties, it can lead to a reduction in expenses and greater empowerment levels to any business. That ledger tells them how much money they have invested, divested, paid out, received, etc. This ledger is vulnerable though, as the bank controls it centrally. This means there is a location you or a hacker could access and alter, theoretically extracting funds, altering or stealing information contained within. Blockchain is this same as a ledger, but DE-centralized. This means that it is not kept in one location, or owned by one entity.

The Leading Destination for IoT

Construction is notoriously a conservative domain. Yet, with the rise of urbanization and population around the world, the need for new buildings, hence, construction, is direr than ever.

Over the next 80 years, the booming global communities will require two billion more homes to accommodate their new needs. These unprecedented challenges, coupled with the pressing need to digitize and innovate, mean construction is ripe for disruption.

Blockchain, one of the most ubiquitous technologies of Industry 4. The block includes a record, which can contain information about any exchange, such as a deal or a financial transaction.

The chain is where all the blocks are linked together. The network keeps updating itself and making changes to ensure that all the copies in the database are the same. Thus, blockchain is an incorruptible and decentralized public ledger to store digital information.

Blockchain rose to fame as the technology behind BitCoin. While these technologies took the financial world by storm, cryptocurrencies are just one of the countless applications of blockchain. A single block can usually contain up to 1 MB of data , meaning that a it alone can contain the information of thousands of transactions.

The construction is a process that requires many professionals who need to collaborate and exchange data for designing, implementing, and operating projects. When this complexity is what makes construction a conservative and inefficient sector, it also means construction is an ideal field to benefit from blockchain technologies.

Blockchain can help to carry construction to the Industry 4. At its core, blockchain is an information technology and a bookkeeping revolution that can adapt to structural problems of construction. In a sector dominated by paperwork like bids, tenders, contracts, permissions, claims, and many more administrative details, blockchain can automate and optimize many of these processes.

These can provide a comprehensive platform where project design, administration, and management transactions simultaneously happen. In construction, smart contracts can improve and automate a diverse range of tasks, from planning to final touches. For instance , a construction laborer enter can trigger a process by entering the site using the ID card for security, health, and safety reasons.

The blockchain-powered system can register how much time they spend working and process a smart contract to automate their payment. Even though this is a straightforward example, developers can scale up the blockchain technologies in countless different ways to make every stage of the construction much more efficient. From regulators, builders, designers, insurers, or lawyers, construction is a multi-faceted team effort.

Trust among all these stakeholders is what oils the engine to run the operations smoothly. As a database architecture technology, blockchain allows every stakeholder to streamline and manage all the data in one reliable and incorruptible ledger. It can bridge the gap of trust by facilitating information exchange via chronological record keeping.

Furthermore, the blockchain system is far cheaper than any other shared database system, such as regular cloud solutions. According to Scott Nelson , CEO of Sweetbridge, a blockchain-based economic framework, the nature of construction makes it a uniquely good fit for taking advantage of blockchain.

Classic project management techniques still work, but projects can benefit from a more decentralized and agile approach, where transparency is high, and parties can be compensated for outcomes as well as for work performed. The construction sector is a significant source of pollution and carbon emissions. It causes more water and air pollution incidents than any other industry. Constructions and buildings are responsible for 39 percent of all carbon emissions in the world, with operational emissions accounting for 28 percent.

While the awareness about greener practices is on the rise, sustainable construction is yet to go mainstream. However, blockchain can help to accelerate this process globally. Blockchain can act as a passport for the building materials. Access to product history will also enable project managers to see whether raw materials or products come from ethical sources.

Thus, blockchain can be a dominant force to drive the circular economy in construction and embolden positive behavior change. In the meantime, greener and more efficient construction projects enable significant cost savings with overheads, administration, and project control. Often cited as the technology that is kickstarting the "second era of the internet", blockchain is already transforming the world of business and human affairs. Popularized as the technology behind BitCoin, blockchain is a decentralized database stored on different computers as identical copies.

The new restrictions and sensitivities introduced to our societies by COVID forced many architects and designers to re-think and re-imagine our built environment.

The result is an accelerating number of buildings designed to minimize touch, optimize fresh air flow, and manage foot traffic more efficiently. A rising alternative to this is the circular economy, a holistic approach to economic progress to benefit businesses, society, and the environment.

Blockchain boost for 'smart' contracts

Published in Advances in Soft Computing in This paper presents an implementation of smart contracts by integrating BIM and blockchain. After briefly reviewing the literature regarding blockchain technology, smart contracts, and integration of the BIM and blockchain, a blockchain network using Hyperledger fabric is proposed and tested to govern a sample construction project. The proposed framework does not utilize the cryptocurrency aspect of the blockchain as the payment form. Instead, it discusses the integration of the current banking system and the use of fiat currencies in transactions. The results show that blockchain is a viable system for governing construction project contracts by automating the consequences of each transaction and maintaining a tamper proof record of project progress, which would be valuable in any kind of dispute resolution. The blockchain network developed in this study implements the smart contract as its network operation logic.

IoT is enabling the digitalization of assets and processes in the construction industry at a fast pace. Construction projects are generally complex and involve a lot of regulations and standards. As a result, the industry now has increasing amounts of fragmented repositories of data in addition to a growing list of intermediaries. Construction companies should leverage the combination of blockchain and IoT to increase transparency in cost, time and scope of projects. A record cannot be altered retroactively without the alteration of all subsequent blocks and the consensus of the network. This allows the participants to verify and audit transactions inexpensively and create trust and transparency, and it eliminates paper and duplicate effort. There are different approaches to implement blockchain technologies.

BIM and Blockchain

He is an expert in transformation and digitalization of corporate processes in construction. Valero, who is also professor at Zigurat Global Institute of Technology, stresses in his article the need to work in safe and controlled collaborative environments when working with BIM, which Blockchain technology can guarantee. A BIM model really works as a large container of parameterized, interconnected, modifiable and graphically representable information. All of which is reusable during the entire life cycle of the asset.

And if tomorrow the blockchain “disintermediated” the construction sector?

As a vibrant industry in a resource-limited city, construction in Hong Kong is highly relied on construction logistics and supply chain management CLSCM around a more connected globe. Almost every piece of construction materials and components must be sourced from outside suppliers and transported back to congested sites in Hong Kong. The CLSCM attracts much more attention from multiple stakeholders, especially as more expensive assets such as complex precast components and Modular integrated Construction MiC units are shipped every day. The local universities and the industry have collaboratively developed a world-renowned reputation by embracing the latest technological solutions to CLSCM, e.
