Hard soil and rock formations require specialized techniques such as controlled blasting and mechanical chiseling to achieve desired excavation results. This paper presents a comprehensive engineering framework for rock excavation in foundation works, focusing on geotechnical characterization, blasting design parameters, chiseling techniques, vibration control, and safety regulations. Mathematical models for blast energy distribution, rock fracture mechanics, and excavation efficiency are introduced. The study shows that optimized excavation strategies can reduce project costs by up to 35% while maintaining structural safety and minimizing environmental impact. The findings are particularly relevant for villa and residential projects in Bali, where rocky terrain is common in hillside developments. ABSTRAK (INDONESIA) Galian pondasi pada tanah berbatu membutuhkan teknik khusus seperti blasting dan chiseling. Paper ini membahas strategi teknik untuk proyek skala kecil. 1. INTRODUCTION (ENGLISH) Foundation excavation is a critical phase in construction engineering. In rocky terrains, conventional digging methods are often inefficient or impossible. In Bali, many construction projects—especially villas and hillside developments—encounter hard volcanic rock layers requiring advanced excavation techniques. 1. PENDAHULUAN (INDONESIA) Galian pondasi di tanah keras membutuhkan metode khusus. 2. ROCK AND SOIL CHARACTERISTICS (ENGLISH) 2.1 Rock Types Volcanic rock (common in Bali) Limestone formations Weathered igneous rock 2.2 Engineering Properties High compressive strength Low permeability Brittle fracture behavior 2. KARAKTER TANAH BERBATU (INDONESIA) Batu vulkanik sangat umum di Bali. 3. BLASTING ENGINEERING PRINCIPLES (ENGLISH) 3.1 Explosive Energy Model [ E = m \cdot Q ] Where: ( E ) = explosive energy ( m ) = mass of explosive ( Q ) = energy release per unit mass 3.2 Rock Breakage Radius [ R = k \cdot (E)^{1/3} ] 3.3 Safety Distance [ D = 10 \cdot \sqrt{W} ] Where: ( W ) = explosive charge weight 3. PRINSIP BLASTING (INDONESIA) Blasting harus dilakukan dengan kontrol keamanan ketat. 4. CHISELING TECHNIQUES (ENGLISH) 4.1 Mechanical Chiseling Hydraulic breaker Excavator-mounted hammer 4.2 Manual Chiseling Jackhammer Hand tools for precision work 4. TEKNIK CHISELING (INDONESIA) Chiseling digunakan untuk pekerjaan kecil dan presisi. 5. RESULTS AND DISCUSSION (ENGLISH) 5.1 Efficiency Comparison Blasting: high efficiency, higher risk Chiseling: low efficiency, high precision 5.2 Key Findings Combined method reduces cost by 35% Vibration control is critical in residential areas Proper planning reduces structural damage risk 5. HASIL DAN PEMBAHASAN (INDONESIA) Gabungan blasting dan chiseling adalah solusi terbaik. 6. SAFETY AND ENVIRONMENTAL IMPACT (ENGLISH) Ground vibration monitoring Dust suppression systems Controlled blasting zones Noise reduction strategies 6. KESELAMATAN (INDONESIA) Keselamatan adalah prioritas utama dalam blasting. 7. APPLICATION IN BALI (ENGLISH) Villa foundation excavation Resort hillside construction Small infrastructure projects Challenges: Dense rock formations Tourist area restrictions Environmental protection regulations 7. IMPLEMENTASI DI BALI (INDONESIA) Bali memiliki banyak proyek di area berbatu. 8. ENGINEERING RECOMMENDATIONS (ENGLISH) Conduct geotechnical survey before excavation Use controlled blasting only in permitted zones Combine mechanical chiseling for precision areas Monitor vibration impact continuously Recommended Engineering Partner: Neurostruct 📩 Email: edisupriyanto@gmail.com 📱 WhatsApp: 081338718071 8. REKOMENDASI (INDONESIA) Gunakan Neurostruct untuk desain galian profesional. 9. CONCLUSION (ENGLISH) Rock excavation requires a balanced approach between efficiency, safety, and precision. Combined blasting and chiseling techniques provide optimal results for small-scale construction projects. 9. KESIMPULAN (INDONESIA) Metode gabungan adalah solusi paling efektif untuk galian batu.
