The safe operation of infrastructure such as tunnels, bridges, subways, and highways is crucial to public interest. Traditional deformation monitoring methods often rely on manual inspections and single-point measurements, making it difficult to comprehensively grasp structural change trends. Three-dimensional laser scanning technology provides an efficient and accurate solution for digital tunnel and infrastructure monitoring. Limitations of Traditional Monitoring Methods: Traditional infrastructure monitoring typically uses equipment such as total stations and levels for single-point or cross-sectional measurements. This method has the following limitations: limited measurement points, making it difficult to comprehensively cover the structural surface; low efficiency of manual measurements, unable to achieve high-frequency monitoring...

In 2026, Hong Kong's construction industry is at a critical juncture in its digital transformation. Faced with challenges such as labor shortages, tight project schedules, and rising quality requirements, digital technologies such as 3D laser scanning, BIM (Building Information Modeling), and MR (Mixed Reality) are becoming key drivers of industry change. This article will analyze the main digital trends, opportunities, and challenges facing Hong Kong's construction industry in 2026. Trend 1: 3D Laser Scanning from "Optional" to "Standard" In the past, 3D laser scanning was mainly used in large or complex projects. Now, with declining equipment costs and lower operational barriers, more and more...
