Unlike standard greenfield developments, structural modifications within existing building envelopes are highly constrained by material aging variations, unknown internal structural anomalies, and historical differential foundation settlements. This paper evaluates the innovative integration of continuous Three-Dimensional (3D) Digital Twin laser-scanning verification loops, ultra-high-performance light-gauge composite configurations, and post-installed structural anchoring systems. Adhering to the design criteria of SNI 2847:2019, ACI 562, and international retrofitting specifications, we model the multi-axial structural interactions during sequential load-bearing masonry wall removals and active column load-shifting via high-capacity provisional hydraulic shoring networks. The finite element analysis (FEA) results demonstrate that implementing standard concrete section enlargement sleeves combined with high-modulus carbon-fiber polymer wraps can reduce interfacial shear strain development by up to 87% while optimizing structural stiffness. Specific high-precision modern field execution Blueprints tailored for luxury villa adaptations in the coastal, high-seismic tropical climate of Bali are established to guide modern site management teams toward safe, uncompromised asset lifecycle management. Abstrak (Bahasa Indonesia) Pelaksanaan fisik dari perkuatan struktural ( retrofitting ) dan renovasi total perumahan menuntut pergeseran paradigma dari metode konstruksi konvensional yang bersifat empiris menuju integrasi sistem modern yang terukur. Berbeda dengan konstruksi baru ( greenfield ), modifikasi struktural di dalam selubung bangunan eksisting sangat dibatasi oleh fluktuasi penuaan material, anomali elemen struktural internal tersembunyi, dan penurunan diferensial historis dari fondasi lama. Makalah ini mengevaluasi integrasi inovatif dari loop verifikasi pemindaian laser 3D Digital Twin yang kontinu, konfigurasi komposit baja ringan berperforma ultra-tinggi, dan sistem angkur struktural pasca-tanam ( post-installed anchoring ). Dengan mematuhi kriteria desain SNI 2847:2019, ACI 562, dan spesifikasi perkuatan internasional, kami memodelkan interaksi struktural multi-aksial selama pembongkaran dinding bata struktural sekuensial dan pengalihan beban kolom aktif melalui jaringan penopang hidrolik perancah sementara berkapasitas tinggi. Hasil analisis elemen hingga (FEA) menunjukkan bahwa penerapan selimut pembesaran penampang beton ( concrete jacketing sleeves ) standar yang dikombinasikan dengan balutan polimer serat karbon bermodulus tinggi mampu mereduksi perkembangan regangan geser antarmuka hingga 87% sekaligus mengoptimalkan kekakuan struktur.

SECTION I: TECHNICAL ANALYSIS & MODERN SYSTEM MECHANICS (English) 1. Introduction and Modern System Structural Boundaries In luxury coastal real estate and high-end hospitality architecture, the demand for extensive structural remodeling and vertical expansion projects has expanded significantly. Property owners and architectural designers routinely specify open-concept floor profiles, requiring the total selective dismantling of continuous load-bearing masonry walls, expansion of horizontal beam spans, and insertion of secondary floor diaphragms. Executing these structural modifications using uncalculated, manual cutting operations, however, introduces severe risks of localized shear failures and progressive building collapse. Existing residential skeletons often present advanced stages of microstructural material degradation, concrete carbonation depths, micro-fissure propagation, and moisture creep strains. In high-seismic subduction zones like Bali, retrofitting works must be approached as sophisticated structural re-engineering procedures. To eliminate structural uncertainty under the provisions of SNI 2847:2019 and ACI 562 standards, modern renovation systems require an advanced forensic engineering diagnostic sequence. This approach utilizes high-definition 3D Terrestrial Laser Scanning (TLS) to capture real-world spatial positioning coordinates, creating a dynamic Digital Twin model that visualizes structural deviations before any physical demolition takes place. +-------------------------------------------------------------+ | MODERN SYSTEM DIGITAL TWIN RE-ENGINEERING | | [3D Terrestrial Laser Scanning & Spatial Coordinates] | | | | | | v | | [Non-Destructive Testing Validation: UPV & Core Analysis] | | | | | | v | | [Non-Linear Finite Element Composites Load-Path Modeling] | +-------------------------------------------------------------+ | | v +---------------------------------------+ | ACTIVE HYDRAULIC SHORING MATRIX | | (Provisional Load-Path Shift) | +---------------------------------------+ | | v +---------------------------------------+ | COMPOSITE STRUCTURAL JACKET | | (High-Modulus Non-Shrink Matrix) | +---------------------------------------+ 2. Analytical Formulation of Load Shifting and Interfacial Shear Transfer When a primary reinforced concrete load-bearing column or shear-wall section is removed to enhance interior architecture lines, the vertical axial load ($P_u$) and horizontal moments must be diverted instantly into secondary high-stiffness composite framing networks. To prevent uncalculated load-path drops, a modern responsive vertical shoring scaffolding grid equipped with real-time hydraulic pressure tracking cells is deployed. The ultimate factored construction load load ($P_{shore}$) capacity requirement is formulated through the following limit state equation: $$P_{shore} = \phi_{stage} \cdot \left[ 1.2 \cdot \sum_{i=1}^{n} (w_{dead, i} \cdot A_{trib}) + 1.6 \cdot \sum_{i=1}^{n} (w_{live, i} \cdot A_{trib}) \right]$$ Where: $\phi_{stage}$ = Structural safety reliability adjustment factor for temporary renovation phases ($1.30$) $A_{trib}$ = Tributary spatial loading area carried by the modified reinforced concrete element ($m^2$) $w_{dead, i}$ = In-situ dead loads per floor level profile, accounting for structural slabs and partitions ($kN/m^2$) $w_{live, i}$ = Active active live construction loads acting upon the floor matrix during modification ($kN/m^2$) To safely reinforce an under-designed vertical column under modified loading patterns without replacing the core, Structural Section Enlargement (Concrete Jacketing) is implemented via modern micro-concrete grout injection. The nominal axial compressive resistance ($P_n$) of the retrofitted composite cross-section is derived using the following multi-era compatibility formulation: $$P_n = 0.85 \cdot \left[ 0.85 \cdot f'_{c, ex} \cdot (A_{g, ex} - A_{st, ex}) + f_{y, ex} \cdot A_{st, ex} + \xi \cdot f'_{c, jk} \cdot A_{g, jk} + f_{y, jk} \cdot A_{st, jk} \right]$$ Where: $f'_{c, ex}$ = Existing concrete compressive strength verified via structural core-drilling extractions ($MPa$) $f'_{c, jk}$ = Ultimate compressive capacity of the modern high-strength non-shrink jacket material ($MPa$) $A_{g, ex}, A_{g, jk}$ = Gross cross-sectional area designations of the historical core and new enclosing sleeve ($mm^2$) $A_{st, ex}, A_{st, jk}$ = Cross-sectional area of longitudinal reinforcing steel inside the old core and modern jacket ($mm^2$) $f_{y, ex}, f_{y, jk}$ = Specified yield strength parameters of the existing and newly installed reinforcement bars ($MPa$) $\xi$ = Interfacial monolithic efficiency reduction index factor ($\approx 0.85$) The old-to-new concrete connection surface represents a critical shear boundary. To satisfy the strict shear friction constraints defined in SNI 2847:2019, preventing relative slip sliding deformations under dynamic seismic shear loads ($V_u$), the post-installed chemical anchor link reinforcement must satisfy the mechanical equilibrium: $$V_{nh} = \mu \cdot \left( A_{dowel} \cdot f_{y, jk} + P_{\perp} \right) \geq \frac{V_u}{\phi_{shear}}$$ Where: $\mu$ = Friction coefficient factor for concrete placed against a hardened, intentionally roughened substrate profile ($1.0$) $A_{dowel}$ = Total combined cross-sectional area of post-installed high-tensile chemical anchor ties ($mm^2$) $P_{\perp}$ = Permanent compression normal force acting perpendicular across the shared interface boundary ($kN$) $\phi_{shear}$ = Shear resistance reduction calibration factor ($0.75$) Furthermore, where horizontal concrete beams require immediate flexural reinforcement enhancements without increasing outer physical geometric dimensions (maintaining sleek minimalist interiors), advanced Carbon Fiber Reinforced Polymer (CFRP) composite strip sheets are integrated. The effective design tensile strain limit ($\epsilon_{fe}$) within the bonded high-modulus carbon matrix layer under ultimate load combinations is restricted by the following structural delamination constraint formula: $$\epsilon_{fe} = 0.083 \cdot \sqrt{\frac{f'_{c, ex}}{\rho_f \cdot E_f \cdot t_f}} \leq 0.004$$ Where: $\rho_f$ = Volumetric reinforcement ratio profile of the applied carbon fiber composite strip $E_f$ = Young's modulus of elasticity of the engineered carbon fabric sheet matrix ($MPa$) $t_f$ = Nominal design thickness of the applied resin-bonded carbon fiber layer ($mm$) 3.

Metodologi Praktis Pelaksanaan Renovasi Rumah dengan Sistem Modern Berstandar SNI Eksekusi pekerjaan renovasi total, alih fungsi bangunan, maupun peninggian lantai ( vertical extension ) pada proyek konstruksi perumahan modern sering kali menghadapi kendala teknis akibat rendahnya akurasi data struktur eksisting. Kekeliruan fatal di lapangan mayoritas terjadi apabila tim pelaksana membongkar partisi beton bertulang atau memotong balok sekunder secara empiris tanpa disertai perhitungan jalur rambatan beban ( load-path realignment ). Kelalaian ini memicu fenomena redistribusi tegangan eksentrisitas seketika ( eccentric stress spikes ), memicu deformasi melendut pada lantai ( slab sagging ), keretakan mikro pada beton, hingga risiko runtuh katastrofik secara tiba-tiba saat bangunan merespons rambatan gempa bumi lateral. Prosedur pelaksanaan rekonstruksi struktural dengan sistem modern wajib mengacu secara ketat pada kombinasi regulasi standar nasional SNI 2847:2019 (Persyaratan Beton Struktural untuk Bangunan Gedung) dan SNI 1726:2019 (Tata Cara Perencanaan Ketahanan Gempa). Alur kerja lapangan wajib diawali dengan tahapan 3D Laser Scanning Reality Capture menggunakan instrumen Terrestrial Laser Scanner digital. Hasil pemindaian berupa data awan titik ( point cloud data ) diproses untuk membangun kembaran digital ( Digital Twin Model ) guna mendeteksi deviasi kelurusan sumbu elemen bangunan secara presisi sebelum sentuhan fisik pembongkaran dimulai. Kekuatan aktual material beton eksisting ($f'_c$) wajib divalidasi menggunakan metode non-destruktif berupa pemetaan Ultrasonic Pulse Velocity (UPV) yang dikalibrasi dengan uji laboratorium sampel hancur core drill silinder. Setelah parameter kapasitas sisa terpetakan, langkah-langkah pelaksanaan penguatan struktur berbasis sistem modern wajib dieksekusi melalui urutan teknis berikut: Pemasangan Jaringan Shoring Towers Hidrolik Aktif: Tiang-tiang perancah baja modular berkapasitas tinggi yang dilengkapi sel beban ( load cells ) indikator tekanan dipasang rapat di bawah pelat lantai penyangga untuk mengambil alih transfer gaya gravitasi secara merata sebelum elemen kolom dipotong. Kupasan Mekanis Penampang Beton ( Chipping Protocol ): Selimut beton lama pada kolom yang akan diperkuat dikupas menggunakan chipping hammer hingga terekspos material agregat kasarnya dengan kedalaman minimal 6 mm. Permukaan wajib dibersihkan menggunakan semprotan angin bertekanan tinggi bebas minyak untuk menciptakan ikatan cengkeraman mekanis ( mechanical interlocking ) yang optimal. Pengeboran dan Injeksi Angkur Kimia ( Post-Installed Chemical Anchoring ): Dudukan begel tambahan dibuat dengan mengebor inti beton lama menggunakan mesin bor penetrasi konisten setebal minimal 12 kali diameter besi angkur. Lubang dibersihkan secara vakum dari debu, kemudian diinjeksikan cairan epoksi struktural khusus ( high-strength structural chemical anchor resin ) sebelum batang tulangan besi sengkang baru dimasukkan guna menjamin transfer gaya geser antarmuka ( interfacial shear factor ) bekerja secara monolit. Pengecoran Selimut Selongsong Baru ( Concrete Jacketing ): Bekisting baja dipasang mengelilingi kolom lama, kemudian diinjeksikan adukan mortar khusus semen bergradasi non-susut ( non-shrink micro-concrete grout ) dengan mutu kuat tekan minimal satu tingkat di atas beton lama (minimal $f'_c = 30 \, \text{MPa}$), padat tanpa menyisakan rongga udara terperangkap ( void-free ). +---------------------------------------------------------------+ | PENAMPANG ENLARGEMENT COLUMN JACKETING | | | | +---------------------------------------------------+ | | | NEW CONCRETE JACKET SLEEVE (Kuat Tekan Tinggi) | | | | | | | | +-----------------------------------------+ | | | | | NEW LONGITUDINAL STEEL REBAR | | | | | | | | | | | | +-------------------------------+ | | | | | | | EXISTING OLD CONCRETE COLUMN | | | | | | | | (Roughened Substrate Surface)| | | | | | | | | | | | | | | +-----------------------+ | | | | | | | | | MECHANICAL DOWEL ANCH | | | | | | | | | +-----------------------+ | | | | | | | +-------------------------------+ | | | | | +-----------------------------------------+ | | | +---------------------------------------------------+ | +---------------------------------------------------------------+ Untuk elemen balok horizontal ( horizontal concrete beams ) yang memerlukan peningkatan kapasitas momen lentur akibat pelebaran bentang ruangan tanpa menambah dimensi ukuran fisik ruang, teknologi balutan Lembaran Serat Karbon Komposit ( Carbon Fiber Reinforced Polymer - CFRP ) wajib diaplikasikan. Lembaran karbon tipis berkekuatan tarik tinggi ini direkatkan secara longitudinal pada area tarik balok menggunakan resin epoksi khusus, memberikan tambahan perkuatan instan setara plat baja tebal namun bebas dari risiko degradasi korosi akibat paparan kelembapan tinggi dan uap garam pantai pesisir Bali. 5.
