Smartym Pro had a task to integrate Hyperledger Fabric framework into a global blockchain-based construction monitoring tool. The main objective was to enable monitoring objects construction process in real-time and provide the rights for specifically authorized people to approve or reject the materials’ statuses and thus control the milestone planning as well as construction stages completion. The system must preserve the integrity of all data and its full history, that will be impossible to fake, change or delete.
We’ve developed a comprehensive Hyperledger-based solution for speeding up the construction audit process by automating milestone planning. The system had to resolve common issues that are faced by both developers and constructors: mutual trust, compliance with the contract’s terms and conditions, fast critical situation handling. We integrated smart contracts into the system to help establish reliable relationships between all the legal entities involved in the construction process, enabled custom RFID tags ID generation and recognition with the help of RFID scanner in mobile app and introduced real-time construction monitoring tools: statuses for every material and component used (from shipment to utilization), traceable and transparent history (all the data is being stored in the Blockchain network and all the modifications and changes can be traced).
1. System logic
The project has a high level of technical and logical complexity. One of the most difficult parts for the members of our development team was to understand the logic of the system, and therefore develop trigger mechanisms for smart contracts according to a complex supply chain logic;
2. RFID tags scanning and processing
We had to use a third-party application for RFID tags recognition and integrate its features in our custom blockchain, so that the network stored the RFID tags data and the statuses of their approvals/rejections.
1. Hyperledger data storage:
2. Mobile app with the ability to update statuses for every component or material:
3. Checking the progress of construction stages with the help of smart-contracts:
4. Traceable supply chain statuses from the moment of shipment until the fact of the installation.
We have delivered an MVP Hyperledger-based product that corresponds to our customer’s needs and expectations. We presented a system, that is fully transparent, tamper-proof, comfortable and intuitive to use.
In perspective, we are planning to implement integration with Building Information Modeling (BIM) mechanics in order to make construction process monitoring even more visual and traceable. All the components marked with RFID tags will be presented on the 3D model, the users of the system will be able to monitor even more information about the construction process, thus enabling better construction management process and preventing possible scams. For example, interested parties will be able to monitor the installation of every construction component step-by-step.
