Construction management use case design by Maikel

1. 3. If applicable, provide a brief description of your business
At this time, a large number of people were busy with construction work. Starting with
residential buildings, offices, hotels, entertainment venues and so on, our scope of
construction is very broad. The transparency that exists in the blockchain supply chain will
be very beneficial during the construction process.
4. What types of stakeholders are involved in your supply chain?
1. Project Owner
2. General Contractor
3. Subcontractors
4. Supplier of Construction Materials
5. Architects and Engineers
6.Project Supervisor
7. Government and Regulatory Authorities
8. Banks and Financial Institutions
9. Financial and Legal Consultants
10. Construction Workers
11. Community Stakeholders
5. What are the roles of each stakeholder in the supply chain?
1. Project Owner
Project leaders oversee the planning, financing, and management of construction
ventures. The blockchain enables the real-time tracking and management of financial
transactions, expenses, and project progress.
2. General Contractor
In leading the construction project, the general contractor acts as a vital coordinator.
Blockchain technology enables the efficient management of subcontractors, schedules,
and payment transparency.

2. 3. Subcontractors
Subcontractors execute specific tasks, utilizing the blockchain to register their completion
and transmit up-to-date progress updates instantly.
4. Supplier of Construction Materials
The integration of materials inventory and information delivery into the blockchain is a
possibility for construction suppliers. Ensuring accurate material availability and
monitoring shipments is the primary goal.
5. Architects and Engineers
With the blockchain as a medium, architects and engineers can collaborate on project
designs and plans, ensuring relevant data access and enabling changes as needed.
6.Project Supervisor
The blockchain allows project supervisors to monitor work progress and quality by
recording daily reports, inspections, and tests.
7. Government and Regulatory Authorities
Compliance monitoring, permit issuance, and approvals are some of the responsibilities
that regulatory agencies can manage through blockchain technology. By enforcing
standards and obtaining essential permits, government and regulatory agencies guarantee
the successful and on-time completion of construction projects. Blockchain enables
accurate monitoring of regulation adherence and accelerates permit, inspection, and
approval procedures.
8. Banks and Financial Institutions
Blockchain facilitates clear and secure payment monitoring and project financing for banks
and financial institutions. Not only do banks and financial institutions provide funding, but
they also process payments to these parties. Real-time tracking of financial flows and
payments can be facilitated by blockchain, mitigating the risk of errors or hold-ups.
9. Financial and Legal Consultants
Secure contract and agreement recording, along with streamlined payment processes and
legal settlements, are just some of the ways financial and legal consultants can benefit from
blockchain technology. The blockchain provides financial consultants with a platform to
securely and efficiently manage contracts, agreements, and transactions. Leveraging this
technology, legal consultants can streamline project-related legal work, encompassing
contractual agreements and dispute resolution.

3. 10. Construction Workers
By incorporating blockchain, construction workers can successfully report their
attendance, work completion, and participate in a more transparent payment system.
Incorporating blockchain technology enables construction workers to more precisely log
their attendance, work reports, and project participation. Furthermore, they can use this
platform to obtain details regarding their assignments and work schedule.
11. Community Stakeholders
Through the blockchain, environmental and community stakeholders can track
environmental effects and project involvement. Stakeholders can employ blockchain to
observe the environmental and social consequences of projects. The use of this
information enables construction projects to be undertaken with an eye toward
environmental sustainability and the welfare of the community.
6. Which stages are included in the supply chain process?
1. Planning and Design
During this stage, project planning, designing plans, and defining project requirements are
crucial. Information related to designs, plans, and specifications can be efficiently managed
and accessed through the blockchain.
2. Acquisition of Construction Materials
In this phase, material suppliers and purchases are selected. Real-time monitoring of
material availability, pricing, and purchase transactions are made possible by blockchain.
3. Procurement of Subcontractors
Subcontractors can be brought in as required during this stage. By leveraging blockchain,
work agreements can be made more transparent through subcontractor contract and
payment monitoring.
4. Project Management
With the aid of blockchain, general contractors and other parties involved in the project
collaborate, monitor development, and manage timelines. Protecting important data like
progress reports and plan changes, secure storage offers a reliable solution.
5. Delivery of Materials
Blockchain documentation tracks the supply chain from the supplier to the project
location. Timely availability of necessary materials is guaranteed by this.

4. 6. Construction Implementation
In this phase, the blueprint takes form as the physical structure is erected. The blockchain
grants access to information regarding finished work and ongoing project advancement.
7. Supervision and Inspection

Adherence to standards is guaranteed, therefore.
8. Financial Management
Financial dealings, from payments to contractors, subcontractors, and providers, are
stored on the blockchain. This guarantees transparency and accuracy in the financial flow.
9. Project Completion
After completion, the blockchain stores information about final inspection and final
approval, project completion.
10. Operation and Maintenance
The blockchain serves as a repository for data related to maintenance, repair, and post-
construction processes. With enhanced asset management and building integrity, this tool
enhances project owner experiences.
