■ Q-Pocket Upgraded with QCON v3, Digitizing the Entire Concrete Quality Control Process


■ Real-Time Sharing and Centralized Management of Quality Data to Improve On-Site Quality and Enhance Transparency in Construction and Quality Management


■ Aims to Deploy Smart Quality Management Systems Across All Construction Sites and Promote Industry-Wide Adoption by Making Patented Technologies Available



Workers use Q-Pocket to conduct ready-mix concrete quality checks on mobile devices at a Hyundai E&C construction site.


Hyundai E&C is leading the digital transformation of construction sites by advancing quality management through AI and big data.


Hyundai E&C announced on Nov. 5 that it is expanding Q-Pocket, the industry’s first integrated smart inspection system developed in 2021, to cover all aspects of quality management. The platform is also being enhanced to enable real-time information sharing and collaboration among all project stakeholders, including project owners, construction supervisors, contractors and subcontractors.


Q-Pocket is a system for managing on-site quality in real time on mobile devices and the web. It handles everything from drawing up inspection and testing plans to checking materials and monitoring concrete cracks. Its “untact & paperless system” has been patented (Patent No. 10-1959459). When a defect is found during construction, a report is written on the spot, and review and corrective action by subcontractors follow in a single, one-stop process.


The enhanced Q-Pocket platform introduces “QCON v3” for concrete quality management, a new "Defect Management" module linking concrete segregation and exposed rebar tracking, and an "OSC Management" module for factory-made components used in off-site construction (OSC). It also uses AI-powered intelligent character recognition (ICR) to automatically digitize quality managers' handwritten records from photographs, improving data accuracy and management efficiency.

Concrete Segregation: A phenomenon in which the materials that make up concrete, such as sand, gravel and cement, fail to stay evenly mixed and separate.


Among the upgrades, QCON v3 stands out. Hyundai E&C first developed QCON v1 in 2018 to improve the efficiency of on-site concrete quality management by allowing inspection results to be entered through mobile devices. The company later introduced v2, incorporating patented, big data-driven quality prediction technologies, including ▲a real-time system for tracking ready-mix concrete truck dispatches and mix conditions① ▲a quantitative quality index system for individual ready-mix concrete suppliers② ▲a system for predicting concrete strength by day③. QCON v3 takes these capabilities further by integrating weather forecasts from the Korea Meteorological Administration through the Public Data Portal, enabling concrete pouring schedules to be planned around temperature and rainfall. The upgraded mobile platform also improves the accuracy of concrete curing in hot and cold weather and extends its capabilities to defect and crack management.

*①Integrated Ready-Mix Concrete Control System and Method (Patent No. 10-2783604), ②Big Data-Based Ready-Mix Concrete Supplier Evaluation System and Method for the Construction Sector (Patent No. 10-2738692), ③Big Data-Based Concrete Strength Prediction System for the Construction Sector (Patent No. 10-2863900)

**Cold-Weather Concrete: Concrete placed when the average daily temperature is 4℃ or below, while still reaching the required quality strength.


With this upgrade, Hyundai E&C will bring the entire concrete quality management process onto a single digital platform, covering ▲concrete pouring plans ▲ready-mix concrete production and dispatch monitoring ▲curing management ▲defect management ▲compressive strength testing and crack management.

Hyundai E&C is also working with specialized IT companies to promote broader adoption of these technologies. In August, the company signed a licensing agreement with Softzion covering three QCON-related patents, paving the way for its concrete quality management technologies to be used across the construction industry.

“Since becoming the first in the industry to develop Q-Pocket, an integrated smart quality management system, and put it to work at its sites, Hyundai E&C has systematized the entire on-site quality control process through continuous upgrades and technology development,” a Hyundai E&C official said. “We will keep advancing our AI-based analytics and our framework for using site data, not only to broaden the use of smart quality control technology but also to apply it at 100 percent of our sites.”

Q-Pocket has also won outside recognition for its technical strength and practicality. It has been registered on the “Smart Construction Technology Plaza,” a technology data-sharing system under the Ministry of Land, Infrastructure and Transport. It also advanced to the finals of the smart technology division in the complex and housing category of the “2026 Smart Construction Challenge,” hosted by the ministry.
