Blockchain-Based Construction Quality Management Method and System

Construction Quality Management System with Enhanced Reliability via Blockchain-Based Anti-Tampering

This technology consists of a blockchain server that performs authorization verification, quality compliance checks, latest block generation, and anti-tampering measures in response to quality management information generation requests from worker terminals, along with an off-chain database that stores the verified original data.

Existing construction quality management systems have limitations in ensuring the reliability of quality information due to the potential for record tampering.

By verifying and recording quality management information on a blockchain while storing the original data off-chain, this technology can be applied to construction quality management to prevent record tampering and enhance overall reliability.

Key Features:

• A blockchain server that verifies worker authorization and quality compliance when a request for quality management information is made from a worker terminal.
• A blockchain server that manages quality management information by generating the latest blocks and determining whether tampering has occurred.
• An off-chain database that stores the original data of quality management information once quality compliance verification is complete.
• Quality management information including photos, videos, sensor data, BIM, and document records collected at construction sites either individually or at set time intervals.
