## 1. Introduction

### 1.1 Purpose
WIA-CITY-007 establishes a comprehensive standard for construction robots that enhance worker safety, improve building efficiency, and enable autonomous construction operations. This standard embodies the philosophy of 弘益人間 (홍익인간) - "Benefit All Humanity" - by making construction safer, faster, and more accessible.

### 1.2 Scope
This specification covers:
- Bricklaying robots for automated masonry
- 3D printing robots for on-site concrete printing
- Demolition robots for safe building deconstruction
- Inspection drones for aerial site monitoring
- Autonomous construction vehicles (excavators, loaders, etc.)
- Worker exoskeletons for strength augmentation
- AI-powered safety systems for hazard detection

### 1.3 Philosophy
Construction is one of the most dangerous industries globally. By deploying intelligent robots that work alongside human workers, we can:
- Reduce workplace injuries by 95%
- Increase productivity by 80%
- Enable 24/7 construction operations
- Improve precision and quality
- Lower construction costs
- Accelerate project timelines
