General Introduction
This course is primarily focused on training trainees in subgrade construction, quality assessment of subgrade projects, and acceptance of subgrade works. The course covers fundamental skills
and methods such as reading construction drawings, devising plans, technical briefings, construction surveying, maintenance operations, and quality inspection and monitoring.

This Course is for
● Helping trainees become familiar with the foundational theoretical knowledge of subgrade construction.
● Enabling trainees to understand the Four New aspects of subgrade construction knowledge.
● Empowering trainees to master subgrade construction methods and process flows.
● Enabling trainees to develop construction organization designs and construction plans for routine subgrade projects.
