Blockchain and the ‘Internet of Things’ for the construction industry:…

- - - - Blockchain & the IoT
        
        It enables them to :grey_question:
        
        Share data between devices without the need for human contact
        
        IoT sensors are used to :point_right: bring value-added services to internet devices
        
        In the construction business :point_right: blockchain is being used
  - - - It can be viewed as a complement to :grey_question:
        
        Electrification
        
        Computerization processes
        
        Existing mechanization
  - - - Aid researchers in :point_right: developing a number of construction engineering solutions
        
        :check: It presents an up-to-date picture of each technology's most recent developments
- - - - To draw a map for future researchers to :point_right: deal with the identified limitations
    - - Subsequently, reflecting the use cases & potential applications of integrating them within the construction industry
    - - Through :point_right: conducting a scientometric analysis
- - - - Blockchain/Distributed Ledger Technology (DLT)
      - Smart Contract Applications in Construction
      - IoT applications in Construction
      - IAMs
      - BIM & BML
      - IoT
  - - - Derive qualitative data analysis from selected articles
  - - - When the objective of the research is to :arrow_right: define gaps in the body of knowledge & identify future research trends
        
        Employing a mixed methods systematic review :mag_right: enables researchers to form an objective presentation of the field
  - - - assets management,
      - project progress evaluation,
      - operational and
      - leveraging BIM implementation and
      - collaboration,
      - enhancing the delivery of prefabricated buildings.
      - supply chain management,
- - - - Innovation
      - Supply chain management
      - Security
      - IoT integration
      - Transportation
      - Deep learning
  - - - The figure depicts the network visualisation of analysing (n = 648) papers that are published in the fields of IoT & blockchain integration
  - - - Encourage researchers to publish more in this area
    - - In the last five years, :eight::nine: percent of publications have been published
- - - - Analyzing correlation-versus-cause for multiple causations
    - - Among the technical hurdles
  - - - More dependable data collection
      - Improved visualization
    - - :check: Can provide real-time feedback on all equipment movements on site :arrow_right: allowing dangers to be identified automatically
    - - RFID technology (readers & sensors), particularly for "health & safety" & evacuation planning during the construction phase
    - - Could enable future simulations to forecast similar issues
  - - - The IoT can assist Small & Medium Size Enterprises (SMEs) in carrying out prefabrication processes
    - - Measure gas emissions throughout the construction stage
    - - Using the Internet of Things, Zhong et al. built an integrated model to :question:
        
        Link collected data from a BIM model & Radio Frequency Identification (RFID)
        
        This system was created using :point_right: a variety of devices, including RFID, cloud technologies, & big data
- - - - That include several interactions & inputs from project members
  - - - Is an attempt to manage BIM with smart contracts that allow for
        
        Automatic payments
        
        Insurance
        
        Project tracking
    - - Blockchain can provide :check: an incorruptible, dependable, & transparent method
        
        :heavy_check_mark: This will make it easier for all stakeholders to :point_right: gain secure access to all available data in order to :point_right: manage project funding
        
        :bulb: For better project delivery, it also provides :check: a data-driven digital environment
    - - Reduce the use of paper in communications and exchanges
        
        A platform that allows project partners to share info in a transparent manner is desperately needed :point_up: :star:
  - - - A framework for enforcing & monitoring the data that is entered into a BCN by trusted parties
        
        In terms of executing & monitoring contract terms :point_right: smart contracts eliminate reliance on lawyers/third parties
        
        Once the data has been proven to be accurate :arrow_right: it can be made immutable to improve transparency & security :check::lock:
    - - Public
        
        Accessible to the general public via a consensus mechanism such as Bitcoins
      - Private
        
        Users in the private one have been pre-identified
        
        And the procedure for their consensus should be explicitly specified as well
  - - - :star: The system should be altered to allow for the transfer of fiat currencies rather than cryptocurrencies
        
        Due to the fact that banks now use a private ledger, smart contracts & bank accounts cannot be linked :green_cross:
        
        :bulb:Payments may be sent/received in fiat money if any commercial/central bank agreed to be a part of the distributed ledger
    - - Technology requires :grey_question:
        
        Laws
        
        A governance system
        
        New regulations
- - - - The findings of this study will serve as a starting point for construction researchers, particularly in terms of :point_down:
        
        Automating resource tracking
        
        Improving supplier coordination
