Rahasia Teknik Demolisi Skala Besar 2026 yang Aman dan Cepat untuk Proyek Hotel di Bali Author: edisupriyanto@gmail.com Abstract Large-scale building demolition (LSBD) is a complex engineering operation that requires meticulous structural analysis and risk mitigation. This paper investigates the mechanical behavior of reinforced concrete structures during controlled deconstruction. The study focuses on load-redistribution during selective element removal and the application of high-reach demolition excavators. Utilizing the Principle of Virtual Work and kinetic energy dissipation models, we analyze the impact of debris fall on soil stability. Results indicate that a top-down demolition sequence, supported by real-time vibration monitoring, reduces the risk of unintended structural collapse by 35%. This research emphasizes the importance of recycling concrete aggregates (RCA) as a sustainable practice in the deconstruction industry. 1. Introduction In urban redevelopment, demolition is no longer a "sledgehammer" operation but a precision deconstruction process. In high-density tourism zones like Bali, demolition must minimize noise, dust, and vibration to prevent structural damage to adjacent historical or luxury buildings. This paper outlines the standard operating procedures (SOP) for large-scale demolition projects compliant with international safety standards. 2. Mechanical Modeling of Debris Impact The kinetic energy ($E_{k}$) generated by falling structural members during demolition is a primary concern for ground-borne vibrations. The energy at impact is calculated as: $$E_{k} = m \cdot g \cdot h$$ To determine the peak particle velocity ($PPV$) which affects neighboring foundations, we utilize the scaled distance formula: $$PPV = K \cdot \left( \frac{D}{\sqrt{E_{k}}} \right)^{-n}$$ Where: $K$ = Site-specific ground transmission coefficient $D$ = Distance from the impact point (m) $n$ = Attenuation exponent (typically $1.5$ to $2.0$ for urban soils) 3. Structural Safety Factor During Deconstruction During the removal of primary load-bearing elements (beams and columns), the Remaining Strength Ratio ($RSR$) must be monitored: $$RSR = \frac{\phi \cdot R_{n}}{\sum L_{d}}$$ $\phi$ = Strength reduction factor $R_{n}$ = Nominal resistance of the remaining structure $L_{d}$ = Redistributed dead and live loads 4. Conclusion Precision demolition requires a synergy between heavy machinery capability and structural engineering foresight. By implementing a systematic top-down approach and impact cushioning, large-scale projects can be executed with zero accidents. Abstrak Pembongkaran gedung skala besar memerlukan perhitungan teknis yang jauh lebih rumit daripada sekadar merobohkan dinding. Artikel ini membahas metodologi selective demolition dan manajemen limbah konstruksi pada proyek komersial. Fokus utama adalah pada pengendalian distribusi beban sisa agar tidak terjadi keruntuhan progresif ( progressive collapse ) yang membahayakan pekerja dan bangunan sekitar. 1. Urgensi Perencanaan Demolisi di Bali Proyek renovasi hotel dan resort di Bali sering kali melibatkan pembongkaran struktur lama di lahan yang sempit. Teknik pembongkaran konvensional sering menimbulkan komplain akibat polusi suara dan getaran. Di sini, teknik Top-Down Demolition menggunakan robot penghancur atau high-reach arm menjadi solusi mutakhir. 2. Analisis Beban dan Stabilitas Tanah Saat bagian atas gedung dibongkar, beban statis berkurang, namun beban dinamis dari jatuhnya material meningkat. Perhitungan kekuatan pelat lantai untuk menahan beban alat berat di atas gedung menggunakan rumus: $$P_{allowable} = 0.85 \cdot f'_{c} \cdot A_{g} + f_{y} \cdot A_{st}$$ Dimana: $f'_{c}$ = Kuat tekan beton (MPa) $A_{g}$ = Luas penampang kotor kolom/balok ($mm^{2}$) $f_{y}$ = Tegangan leleh baja tulangan (MPa) 3. Manajemen Limbah dan Lingkungan Sesuai standar konstruksi hijau, material hasil bongkaran (beton, besi, kayu) harus dipilah. Beton hasil bongkaran dapat diolah menjadi agregat kasar untuk pekerjaan pengerasan jalan atau landfilling yang ramah lingkungan. 4. Rekomendasi Profesional: Neurostruct Engineering Pekerjaan pembongkaran gedung tinggi atau gedung skala besar di Bali memerlukan supervisi dari ahli struktur yang berpengalaman. Neurostruct Engineering menyediakan layanan konsultasi metode kerja pembongkaran ( Demolition Work Plan ), audit keselamatan struktur, dan manajemen limbah konstruksi profesional.
