<br />
=Abstract=<br />
Wilson Lu's keynote presentation at CBC 2023 elaborates on the integration of Building Information Modeling (BIM), blockchain technology, and smart core technologies for enhancing cross-border logistics and supply chain management in Modular Integrated Construction (MIC). He shares insights from a recently completed ITF project that his team at Hong Kong University undertook, aimed at solving the complexities surrounding the construction industry in Hong Kong, including high construction costs, an aging workforce, and declining construction techniques and quality.<br />
<br />
Lu explains that MIC, or offsite construction, is a strategic solution to these challenges, emphasizing the production of 3D standalone modules complete with finishing, furniture, and fixtures—akin to containerized Lego pieces. However, Hong Kong lacks local factories for MIC module production, leading to a unique cross-border manufacturing approach with factories in the Pearl River Delta region of Guangdong Province. This necessitates a robust system for quality inspection, logistics, and installation management, areas where blockchain and digital technologies offer significant advantages.<br />
<br />
The core of Lu's presentation centers on the development of a mobile platform to digitalize the logistics and supply chain of MIC, focusing on production processes, cross-border logistics, and onsite installation. This initiative led to the creation of three applications: E-Install for factory quality inspection, E-Transar for cross-border logistics and transportation, and E-Instar for onsite module installation. These apps allow for real-time documentation and quality assurance, leveraging blockchain for immutable record-keeping and IoT technology for tracking and analysis.<br />
<br />
An innovative aspect of the project is the use of an in-house developed IoT technology, I Core, to track the logistics of cross-border module transportation, providing valuable data on location, vibration, and other parameters directly to the blockchain system. This level of transparency and accountability is crucial for ensuring the quality and integrity of construction modules from manufacturing through to installation.<br />
<br />
Lu reflects on the lessons learned and potential areas for further exploration, such as visualizing blockchain systems in a way that is accessible and meaningful to stakeholders, leveraging blockchain oracles for validating off-chain data, and exploring the use of smart contracts for streamlined payments. He also discusses the industry's interest in developing construction-specific blockchain platforms and subscription services to lower the barrier for SMEs in adopting these technologies.<br />
<br />
The presentation concludes with a call to consider the appropriate blockchain platform typology (public, private, consortium, or hybrid) for construction projects and the possibility of creating an industry-specific blockchain platform. Lu emphasizes the potential of blockchain to transform the construction industry by improving efficiency, quality, and trust across the entire supply chain, from manufacturing through to onsite assembly.<br />

<br />
=Abstract=<br />
Daniel Hall and Jens Hunhevicz's CBC 2023 keynote elaborates on the integration of blockchain technology with collaborative project delivery models, particularly Integrated Project Delivery (IPD), in the construction industry. Their discussion revolves around decentralizing project delivery systems to enhance collaboration, manage complexity more effectively, and address the industry's inherent challenges related to coordination and trust among stakeholders.<br />
<br />
The keynote highlights the transformation in project delivery approaches from traditional, centralized models towards more collaborative, decentralized systems. This shift is primarily driven by the need to manage complex projects more effectively. Hall and Hunhevicz argue that decentralized systems, exemplified by IPD, offer a framework for better handling complexity through enhanced collaboration and shared decision-making processes. They explore the concept of projects as common pool resources, drawing parallels between the governance mechanisms in IPD and those governing commons, as outlined by Elinor Ostrom's principles.<br />
<br />
A significant part of their discussion focuses on blockchain technology's potential to further decentralize project governance. Blockchain's attributes, such as transparency, immutability, and the ability to facilitate peer-to-peer transactions without central oversight, are identified as key enablers for developing a new paradigm for project delivery termed "Project Delivery on the Crypto Commons." This concept envisions leveraging blockchain to encode governance mechanisms that align with Ostrom's principles for managing common pool resources, thus fostering a more collaborative, efficient, and trust-based project delivery environment.<br />
<br />
The researchers present a conceptual framework linking blockchain with collaborative project delivery, identifying specific blockchain applications and mechanisms that could support decentralized governance in construction projects. These include identity verification, resource pool tokenization, transparent monitoring, and smart contract-based coordination mechanisms. They suggest that such blockchain-enabled governance structures could improve the efficiency and outcomes of construction projects by aligning the economic and governance systems with the industry's decentralized nature.<br />
<br />
Despite the promising vision outlined in their keynote, Hall and Hunhevicz acknowledge the challenges and complexities involved in implementing such a transformative approach. They highlight the need for further research to operationalize this concept and address practical and technical hurdles.<br />
<br />
The keynote concludes by emphasizing the potential of blockchain technology to complement and enhance existing collaborative project delivery models. By aligning with the industry's decentralized structure, blockchain could enable more resilient, efficient, and trust-based coordination mechanisms, thereby advancing the construction industry's digital transformation.<br />

[[CBC 2023]] presentation by [[Eleni Papadonikolaki]]. https://doi.org/10.47330/CBC.2023.MKJP7058 | Watch [[File:VideoRecord-Icon.png |Left|22px|link=https://www.youtube.com/watch?v=I1DWpdHno7I]] | [[File:Slides-Icon.png |Left|30px|link=https://www.dropbox.com/]]<br />
<br />
=Abstract=<br />
Eleni Papadonikolaki's keynote at CBC 2023 focuses on the exploration of blockchain innovation ecosystems within the construction sector, particularly examining how open or closed these ecosystems are. Originating from a background in architecture with affiliations to notable institutions like UCL and TU Delft, Papadonikolaki brings a rich understanding of both the architectural and managerial aspects of engineering projects to her investigation into blockchain technology's role in construction.<br />
<br />
Her research delves into the peculiarities of the construction industry, which is characterized by its project-based nature, fragmentation, transaction-heavy processes, and a notable lack of trust among stakeholders. These factors contribute to the industry's slow digital transformation compared to other sectors. Papadonikolaki positions blockchain as a potential catalyst for change, given its capacity for transparent and immutable transactions, which could foster a more trust-based environment.<br />
<br />
The keynote further explores the concept of open innovation ecosystems in construction, contrasting them with closed systems. Open innovation, as discussed, allows companies to leverage external knowledge, expertise, and technologies to drive innovation, as opposed to relying solely on internal resources. The study highlights a qualitative analysis based on interviews with experts, revealing a preference towards open innovation within the blockchain domain, yet also noting significant mentions of closed innovation principles, particularly concerning business models and intellectual property (IP) protection.<br />
<br />
Key findings suggest that the construction sector predominantly operates within closed innovation ecosystems, hindered by traditional business models that resist change and impede the free flow of knowledge and collaborative innovation. However, blockchain initiatives have the potential to empower small and medium enterprises (SMEs) by democratizing access to innovative solutions and fostering more equitable participation within the industry's innovation ecosystem.<br />
<br />
The study identifies different orchestrators for open and closed blockchain innovation ecosystems, with consortia playing a central role in open systems, and contractors or asset owners typically orchestrating closed ecosystems. The research emphasizes the critical role of policymakers in supporting these ecosystems, advocating for government involvement in legitimizing and legislating blockchain use in construction to facilitate its adoption and integration into mainstream industry practices.<br />
<br />
Papadonikolaki concludes by stressing the importance of collective and open actions in overcoming the industry's innovation challenges. She critiques the expectation that major tech disruptors will revolutionize the construction sector, arguing instead for a more inclusive and collaborative approach to fostering digital transformation through blockchain and other digital technologies.<br />

<br />
=Abstract=<br />
Ioannis Brilakis' keynote at CBC 2023 focuses on the development and implementation of digital twins within the built environment, setting aside blockchain to concentrate on a more specific aspect of digital innovation. Originating from the University of Cambridge, Brilakis introduces his work within a rich academic heritage, emphasizing the university's contribution to various fields through its notable affiliates.<br />
<br />
His presentation delves into the concept of digital twins, which are essentially digital replicas of physical entities, systems, or processes. These digital counterparts can dynamically update and evolve, offering significant potential for improving the management, operation, and maintenance of infrastructure. Despite their promise, Brilakis points out that digital twins remain largely aspirational due to a lack of standardized definitions, methodologies, and understanding of their economic value.<br />
<br />
One major challenge in the widespread adoption of digital twins is the difficulty in transitioning from static, isolated models like BIM files to dynamic, interconnected systems that accurately reflect real-world changes over time. Brilakis highlights the necessity for research and development to bridge this gap, advocating for the creation of exemplar projects that demonstrate the practical benefits and cost-effectiveness of digital twins.<br />
<br />
Throughout the presentation, Brilakis underscores the importance of differentiating between data and information within the context of digital twins. Effective digital twins should be built from processed, meaningful information rather than raw data, to avoid overwhelming the system and to ensure that it delivers actionable insights. AI plays a crucial role in this process, aiding in the transformation of data into information and knowledge, and facilitating more automated and informed decision-making.<br />
<br />
Brilakis also emphasizes the need for a comprehensive lifecycle approach to digital twins, covering planning, design, construction, maintenance, and operation. This approach challenges current practices by demanding new tools, standards, and frameworks for digital twin development, as well as strategies for maintaining and updating these systems over time to ensure they continue to provide value.<br />
<br />
Furthermore, Brilakis shares insights from his work on automating the creation of digital twins from physical assets using advanced scanning and data processing techniques. This work includes capturing detailed geometries, textures, and conditions of assets, and integrating this information into dynamic models without human intervention.<br />
<br />
In conclusion, Brilakis advocates for a national or even global perspective on digital twins, suggesting that just as nations invest in physical infrastructure to support economic activity, they should also invest in digital infrastructure. By doing so, governments can catalyze economic growth in sectors like construction and engineering, which lack the massive corporations present in industries such as automotive to drive innovation independently.<br />

=Abstract=<br />
Sean Chen's presentation at CBC 2023 focused on the adoption and opportunities of blockchain technology in Hong Kong, emphasizing its impact on the construction and real estate industries. Chen, with a background in digital transformation, BIM, and smart city solutions, has dedicated the last two years to promoting blockchain technology at the infrastructure level to governments and enterprises through his work with RED Technologies. He outlines RED Technologies' two main global projects: the Blockchain-Based Service Networks (BSN) for creating isolated networks catering to mainland China and global data, and the Universal Digital Payment Networks (UDPN) focusing on CBDC and stablecoin cross-border payment networks.<br />
<br />
Chen elaborates on the necessity of compliance-first approaches for blockchain infrastructure, aiming to establish a 'private internet' for enterprise and government use, encouraging a unified platform that supports a variety of protocols and frameworks. This approach allows for the selection of appropriate blockchain protocols based on specific needs without committing to a single technology, promoting efficiency and adaptability.<br />
<br />
Focusing on Hong Kong, Chen discusses blockchain adoption within the construction industry, highlighting potential applications in digital work supervision systems, supply chain finance, and the digital management of construction documentation. He also mentions a Hong Kong developer's project, River Chains, which innovates in supply chain finance by leveraging blockchain for more efficient payment processes.<br />
<br />
A significant part of the presentation is dedicated to the government's efforts in blockchain integration, particularly through the Office of the Government Chief Information Officer (OGCIO) of Hong Kong. This initiative aims to establish a shared blockchain platform to facilitate application deployment across various government departments, promoting a smart city concept akin to Dubai's blockchain strategy.<br />
<br />
Chen proposes several blockchain applications for the construction industry, including document management, digital asset tokenization, smart contracts for invoicing and payments, e-tendering and bidding, and the tokenization of BIM objects. He suggests these innovations could significantly enhance efficiency, transparency, and compliance in construction processes.<br />
<br />
The presentation concludes with a vision for the future of blockchain in enterprise and government, advocating for a consortium-based approach that encourages collaboration and shared infrastructure, paving the way for a more interconnected and efficient implementation of blockchain technology across industries.<br />

=Abstract=<br />
Davide Lombardi's presentation at CBC 2023 offers a comprehensive overview of integrating blockchain technology in the architecture and construction industries to tackle challenges like productivity, supply chain integration, and carbon impact. He emphasizes the sector's inefficiencies when compared to manufacturing, attributing issues to material unavailability, skill shortages, and a reluctance to embrace new methodologies. Highlighting the environmental impact of construction, Lombardi argues for the necessity of sustainable practices and digital innovation.<br />
<br />
Lombardi and his colleagues propose a solution combining technology with social behavior through the concept of "stigmergy" - a mechanism of indirect coordination where agents act on and modify their environment, leading to a collective outcome. This approach is operationalized using blockchain as a digital medium for collaboration, enabling continuous evaluation and adaptation of design and construction processes. The model envisions "collective digital factories" as decentralized autonomous organizations using blockchain and cryptoeconomics to address environmental challenges and improve industry productivity.<br />
<br />
The proposed framework involves agents (e.g., architects, engineers) using simplified topological models rather than complex BIM models for design, facilitated by an application called Topologic. These models serve as a basis for decision-making, governed by tokens that incentivize contributions toward common goals like waste reduction and enhanced building performance. This process is supported by smart contracts that manage governance, evaluation, and reward mechanisms, promoting a collaborative and iterative design process.<br />
<br />
Lombardi suggests that this model could revolutionize the AEC industry by fostering a more integrated, efficient, and sustainable approach to building design and construction. By emphasizing the importance of regulatory compliance and proposing a system that embeds legal frameworks into the digital factories, he outlines a future where technological and social innovations drive the industry towards its environmental and productivity goals.<br />

=Abstract=<br />
Lavinia Chiara Tagliabue's keynote at the CBC 2023 focuses on the integration of BIM validation and smart contracts to expedite payments and bolster green public procurement in the construction industry. She represents the collaborative effort between the Polytechnic of Milan and the University of Turin, emphasizing their commitment to digitizing and optimizing building assets management for sustainability and operational efficiency.<br />
<br />
Tagliabue outlines the extensive scale of the University of Turin's real estate assets, highlighting the challenges in managing such a vast array of historical and modern buildings across different locations. She discusses the initiative to digitize these assets to support space management, enhance user comfort, and ensure inclusive and barrier-free environments. The integration of digital models and BIM methodologies facilitates the creation of an ecosystem that not only improves physical spaces but also enriches the user experience for students and staff.<br />
<br />
Central to her presentation is the development of an asset management system that incorporates data from various university departments, consolidating fragmented information into a comprehensive database. This system employs GIS platforms and business intelligence tools like PowerBI to analyze and visualize space utilization, costs, and user distribution, thereby enabling effective decision-making and resource optimization.<br />
<br />
Tagliabue introduces the concept of using blockchain technology to streamline the design and tendering phases of construction projects. By automating the validation of BIM models against client guidelines and facilitating prompt payments through smart contracts, the process aims to enhance transparency, reduce delivery times, and ensure regulatory compliance. This approach also supports green public procurement by automating the evaluation of environmental criteria, promoting sustainable building practices.<br />
<br />
The research presented by Tagliabue illustrates a high-level framework wherein design teams propose retrofit strategies for buildings, and blockchain is utilized to notarize BIM models, automate compliance verification, and facilitate payments. This framework was tested on the real estate assets of RAI, Italy's public TV company, demonstrating its potential to improve public procurement processes by increasing efficiency, ensuring transparency, and supporting environmental sustainability.<br />

=Abstract=<br />
Sean Hanna's keynote at CBC 2023 explores the intersection of Artificial Intelligence (AI) and Building Information Modeling (BIM) in the context of design, focusing on the concept of managing uncertainty across various stages of a project. Hanna draws parallels between AI and BIM's objective to refine and rely on increasingly accurate models or "single sources of truth" to reduce errors. He advocates for a decentralized approach in utilizing AI in design, suggesting it as a method to manage the inherent uncertainties prevalent in the early stages of design processes.<br />
<br />
Hanna references the Mlini Curve to discuss how early design phases carry significant uncertainty and potential for influence, alongside rising costs as projects progress. He presents examples spanning from pre-design to operational stages, demonstrating AI's capacity to tackle uncertainty throughout a project's lifecycle. For instance, he cites the use of neural networks in predicting building energy performance and computational fluid dynamics to model wind flow around structures more efficiently than traditional simulations.<br />
<br />
A pivotal aspect of Hanna's argument is the distinction between risks, which are quantifiable uncertainties, and "true uncertainty," where probabilities cannot be scientifically determined. He points out that design frequently encounters true uncertainties or "wicked problems," which are not readily addressed by optimizing models or machine learning that seeks to fit patterns within existing data.<br />
<br />
To illustrate the challenge of addressing true uncertainty with AI, Hanna discusses the variability in solving problems like protein folding versus capturing the first image of a black hole. The former, despite its complexity, allows for experimental validation, whereas the latter involves making inferences from irreplicable and distant phenomena, highlighting difficulties in validating AI-generated outcomes against a "ground truth."<br />
<br />
Hanna also examines paradigm shifts in design, where a change in representation or model is required to address new challenges effectively. He uses examples from his work and others', emphasizing that certain creative leaps in design cannot be achieved through linear optimization or model fitting but require a fresh conceptual framework.<br />
<br />
Central to Hanna's proposition is the use of decentralized systems like Speckle, which facilitates data transfer across disparate models without necessitating their reconciliation. This approach aligns with managing the multifaceted uncertainties in early design phases, suggesting a shift from centralized to distributed models as projects move from high uncertainty to greater certainty.<br />
<br />
Concluding his keynote, Hanna underscores the need for further research into decentralized methods of handling design uncertainties, leveraging AI and technologies like blockchain. He suggests that such approaches could enable more fluid negotiation and management of uncertainties, supporting a more adaptive and responsive design process.<br />

=Abstract=<br />
Markus König's keynote at CBC 2023 revolves around the integration of Building Information Modelling (BIM), blockchain technology, and smart contracts within the construction industry, and introduces European initiatives in data sharing and management that could significantly impact these technologies. König shares insights into a project started in 2019, aimed at addressing the complexities of contract management in Germany, which suffers from inefficiencies such as delayed payments, transparency issues, and a high rate of insolvencies. The digitalization shift, notably through BIM-based planning and documentation, offers a fertile ground for implementing blockchain and smart contracts to streamline contract management and payment processes.<br />
<br />
The project envisions an ecosystem where clients, contractors, and subcontractors interact seamlessly, supported by digital contracts that integrate BIM models with standardized bills of quantities and payment plans. The innovation lies in creating smart contracts that can automate payment processes based on verified completion of work, documented securely on a blockchain. This approach promises to mitigate delays and disputes over payments and work quality.<br />
<br />
König also highlights the challenges of integrating digital contracts with traditional paper-based contracts and the development of user-friendly platforms that allow for the easy configuration of contract terms and payment conditions. Despite the potential benefits, he notes the difficulty in convincing the construction industry to adopt these advanced solutions due to the inherent resistance to change and the need for further development and funding.<br />
<br />
In the latter part of the presentation, König introduces the European Union's initiative GAIA-X, aimed at establishing a decentralized data ecosystem across various industries, including construction. GAIA-X focuses on creating a trust layer for data exchange that complements blockchain technologies by providing a structured framework for data sharing, compliance, and identity management. The project embodies a consortium approach to blockchain, deemed most suitable for the construction industry due to its balance between openness and privacy.<br />
<br />
The discussion on GAIA-X expands into how data exchange can be formalized through self-descriptions, catalogs, and smart contracts to facilitate secure, efficient, and equitable data transactions. This model, according to König, has the potential to revolutionize data management in construction by ensuring that data about buildings, materials, and work processes is accessible, verifiable, and reusable beyond the lifespan of individual projects.<br />
<br />
König concludes his presentation without a formal summary, acknowledging the time constraints but leaving the audience with a clear vision of the transformative potential of BIM, blockchain, and smart contracts in construction. The integration of these technologies, alongside initiatives like GAIA-X, could pave the way for more transparent, efficient, and resilient construction processes, though significant challenges in adoption and implementation remain.<br />

=Abstract=<br />
In his keynote at CBC 2023, Max Surf from KPMG Australia elaborates on the transformative potential of blockchain technology in the construction industry. Surf begins by highlighting the urgent need for quality and sustainability in construction, citing the Grenfell Tower disaster as a stark reminder of what can go wrong. He emphasizes that as global construction activity is set to increase dramatically, ensuring quality becomes more challenging yet imperative.<br />
<br />
Surf discusses the Australian context, where significant portions of medium to high-rise buildings have major defects, causing costly remediations. This issue of quality is not isolated to Australia but is a global concern, especially with the shift towards offsite manufacturing and Design for Manufacture and Assembly (DfMA) to enhance speed, quality, and sustainability in construction.<br />
<br />
The construction industry's complex ecosystem of stakeholders poses additional challenges in aligning incentives and actions towards shared goals. Surf proposes the use of a "Building Trustworthy Indicator," a commercial tool developed with the state government in Australia, which assesses construction projects based on three criteria: the participants (trusted participants' financial and conduct history), the materials used, and the construction process itself. This tool aims to provide a simple yet comprehensive trust indicator to consumers, regulators, financiers, and insurers, enabling informed decisions and fostering a proactive and data-driven regulatory environment.<br />
<br />
Surf underscores the critical role of blockchain in achieving this vision. Blockchain's capacity for ensuring data integrity, transparency, and a shared view of reality among all stakeholders in the construction process stands out as a fundamental enabler of change. He posits that blockchain can help align the diverse incentives within the construction ecosystem, promoting quality, sustainability, and efficiency.<br />
<br />
By collecting and securely storing data on who is involved in a construction project, what materials are used, and how the building is constructed, blockchain provides a foundation for trust. This technology not only enables a more transparent and efficient construction process but also paves the way for future automation and smart contracts, which could revolutionize financing, maintenance, and sustainability practices in the industry.<br />
<br />
Max Surf's presentation at CBC 2023 articulates a compelling case for blockchain's role in transforming the construction industry. By fostering a shared, transparent data environment, blockchain technology has the potential to align stakeholders' incentives, enhance quality and sustainability, and prepare the industry to meet its future challenges head-on.<br />

=Abstract=<br />
Yuri Catalo from Autodesk Research delivered a thought-provoking keynote at CBC 2023, focusing on the intersection of blockchain technology and construction, but from a unique perspective rooted in collaboration, innovation, and looking beyond the conventional applications. Catalo, with a background that blends arts and business, offers a fresh view on how Autodesk, and the industry at large, is approaching blockchain's potential. He starts by distancing his insights from Autodesk's official stance, promising an exploration of personal observations and industry trends rather than company policy.<br />
<br />
Catalo points out a consistent theme across several years of discussions on blockchain in construction: the anticipation of revolutionary change. Despite numerous headlines heralding blockchain's transformative potential, real-world applications in construction remain nascent. Highlighting the story of Brick, a company that pivoted from blockchain to AI, Catalo underscores the challenges blockchain faces in gaining commercial traction within the construction industry.<br />
<br />
Furthering his analysis, Catalo likens the current state of blockchain to the dot-com bubble of the 1990s. He argues that, similar to the aftermath of the bubble burst, the foundational technologies and excess capital from the blockchain boom will pave the way for future innovations. Central to blockchain's enduring value is its ability to generate trust, a commodity of incalculable worth that ensures the technology's continued relevance.<br />
<br />
The reluctance within the construction sector to adopt blockchain, Catalo finds, is mirrored in typical industry hesitations towards new software, with a notable misunderstanding conflating blockchain with cryptocurrency. However, parallels drawn from supply chains in other industries, such as HP's component tracking and Starbucks' Odyssey program for coffee traceability, demonstrate blockchain's practical benefits beyond speculative crypto markets. These examples showcase blockchain's role in enhancing transparency, accountability, and consumer engagement.<br />
<br />
Catalo concludes with strategic advice for advancing blockchain integration in construction. He advocates for simplifying the narrative around blockchain, emphasizing its practical benefits over the technological intricacies. Learning from successful applications in other sectors can provide valuable insights into deploying blockchain effectively. Finally, Catalo stresses the importance of collaborative efforts among academia, startups, and industry leaders. By pooling resources and expertise, there's a higher chance of overcoming existing barriers and realizing blockchain's full potential in construction.<br />
<br />
This keynote not only charts a course for blockchain's future in construction but also frames it within a broader context of technological adoption and innovation, urging a collective push towards practical, impactful applications.<br />

=Abstract=<br />
This research aims to enhance operational efficiency and data integrity across the built asset lifecycle by integrating cloud-based Building Information Modelling (CBIM) with blockchain technology. A framework for a decentralized and immutable Common Data Environment (CDE) is proposed, ensuring data security and transparency. The system utilizes smart contracts to record transactions from different CDEs on the blockchain, validating data integrity and storing metadata. To address file size challenges, an integration of Inter-Planetary File Storage (IPFS) is suggested. A web-based prototype was developed and tested with industry experts. Unlike other studies advocating alternative CDE tools, this research recommends integrating existing CDE platforms to facilitate data integration throughout the asset's lifecycle. The results reveal the impracticality of a one-size-fits-all information management tool, emphasizing the need for decentralized solutions to improve trust among construction stakeholders by accommodating diverse project phase requirements. The proposed framework establishes a decentralized and secure foundation for data streams, contributing to increased operational effectiveness and trust in the construction industry.<br />

The construction industry, with its complex processes, is witnessing transformational benefits from blockchain and smart technological advancements. Improved communication, efficient management, and enhanced alliances are becoming key advantages. However, the industry must overcome longstanding habits of working in silos and fostering a "lack of trust" mindset to fully leverage these technologies. The intricate nature of construction projects, involving diverse contributors and a multifaceted approach, calls for a more coordinated and aligned working methodology facilitated by digital advancements.Projects demand effective coordination and collaboration, necessitating a shift from adversarial to collaborative approaches. The industry's contentious nature and reluctance to align commercial interests have led to wasteful disputes, benefiting legal professionals. The adoption of blockchain requires a fundamental change in the industry's culture, fostering trust, aligning goals, and embracing a collaborative environment.To address these challenges, an intelligent environment of trust is crucial, where goals align seamlessly across the entire project team. The construction industry must transition from siloed working to collaborative integration, embracing joint risk management and building shared objectives. A formalized multi-party contractual mechanism, exemplified by the Integrated Information Management Contract (IIMC), provides a framework compliant with international standards. Developed by the Centre for Digital Built Britain, it aligns with the ISO 19650 series, promoting transparency, efficiency, and shared understanding throughout the life cycle of a built asset. This shift towards collaboration and transparent contractual frameworks is vital for the successful integration of blockchain and smart technologies in the construction industry.<br />

=Abstract=<br />
The construction industry faces frequent and costly disputes, causing delays and financial setbacks. Dispute avoidance aims to minimize conflicts early on by addressing the potential sources of conflict at an early stage. This study suggests using blockchain technology and smart<br />
legal contracts to proactively prevent disputes and avoid conflicts. The proposal involves automating common dispute-prone contract clauses in construction megaprojects through blockchain-based smart contracts. A detailed case study on a construction megaproject illustrates how the<br />
proposed system can prevent recurring disputes arising from contract misinterpretations. Some of the potential benefits from this application include savings in cost and time, which would otherwise be incurred in dispute resolution measures along with enhanced collaboration and transparency in the contracting process.<br />
