How does Trimble 3D technology improve the efficiency of airport construction

Trimble 3D technology has significantly enhanced the efficiency of airport construction through automated control, data collaboration and millimeter-level precision management, which is specifically reflected in the following aspects

1. Millimeter-level precision construction reduces rework

Automatic control of paving and slope ‌

In key areas such as runways and aprons, the ‌Trimble PCS900 3D paving control system ‌ and the ‌GCS900 slope control system ‌ are applied to achieve an asphalt/concrete paving accuracy of ‌5 mm ‌ (better than the 10 mm design requirement), and the base flatness strictly meets the standards.

The double-paver cascade operation forms a seamless hot joint, eliminating the risks of water seepage and freeze-thaw, and saving the traditional rework process.

Milling process optimization ‌

The milling machine is equipped with Trimble active tracking targets and is linked with a total station, ensuring stable operation in harsh environments such as dust and rain. It precisely controls the milling depth (such as accurately stripping the bottom 4-6 cm concrete layer), ensuring a smooth and flat base layer.

Second, achieve full-process data collaboration to break down information silos

Design-construction real-time synchronization ‌

By integrating laser scanning and drone survey data through the ‌Trimble Connect cloud platform ‌, 2,700 active BIM models are synchronized in real time to on-site devices to avoid construction delays caused by version conflicts.

Closed-loop management of completion data ‌

Trimble WorksManager‌ transmits design data directly to pavers and other equipment, and feeds back completion data in real time for verification to ensure that construction fully complies with standards, eliminating the need for manual review time.

Trimble WorksOS‌ tracks production progress and generates automated reports instead of the traditional manual recording process.

Iii. Comprehensive Efficiency Improvement

Shortened construction period ‌ : The 3D automation system reduces human intervention and completes the asphalt/concrete laying task ahead of schedule.

Cost optimization ‌ : reducing the manpower for measurement and layout (such as eliminating the need for traditional wire pulling positioning) and lowering material waste (precisely controlling the paving thickness), the overall cost has significantly decreased.

All-weather operation capability ‌ : The active tracking technology operates continuously in dusty, foggy and night environments, breaking through weather and time period limitations.

Industry verification ‌ : The Jorge Chavez airport project in Peru has verified that this technology can systematically address the efficiency bottlenecks of large-scale infrastructure and drive the construction methods towards digitalization.
