1 Introduction

The intelligent construction site digital twin management and control platform is based on technologies such as the IoT, big data, and cloud computing. It assists managers in decision-making and planning. The platform uses digital twin models and data collection systems to accurately reflect the status of the construction site. By comprehensively collecting and analyzing data related to personnel, safety, quality, and the environment, it enables data sharing and collaboration, ultimately leading to the establishment of a smart construction site.

2 Construction Site Overall Management

The construction scope and application management system based on 3D GIS supports map creation, information maintenance, and online submission of applications, while also providing statistical analysis features. The system also enables unified management of the work area through a single map and can link with underground pipeline analysis to ensure that the protection zones of underground utilities are considered when applying for the construction area.

3 Underground Utility Management

The system supports an underground mode, displaying 3D models of underground pipelines and utility corridors while providing information linking, retrieval, and statistical analysis features. It also includes various spatial analysis tools for underground pipelines, such as clearance analysis, surface excavation analysis, path connectivity analysis, topology analysis, and pipeline inspection, enabling efficient management of underground assets.

4 AI Intelligent Recognition

The platform utilizes AI video analysis and image recognition technology to identify personnel behavior, clothing compliance, and on-site hazards in a specific area of the project. It automatically triggers alarm notifications upon detecting unsafe behaviors and hazardous conditions, which are broadcasted through the system as reminders, or it notifies dedicated safety personnel to intervene and address the situation on-site.

5 Personnel and Vehicle Positioning

By integrating the construction site’s 3D model with personnel and vehicle positioning devices, precise positioning and safety tracking services for people and vehicles can be achieved. This allows leadership and supervisory personnel to conveniently conduct modern supervision and management centered around the 3D model of personnel and vehicles.
