This paper evaluates accelerated beam formwork methodologies, focusing on the utilization of modular aluminum systems, high-early-strength concrete (HESC) mixtures, and advanced quick-release shore mechanisms. Integrating analytical modeling compliant with SNI 2847:2019 and ACI 347R structural design frameworks, we analyze the structural performance of horizontal systems under dynamic stripping schedules. The findings demonstrate that combining structural optimization with modular components can reduce cycle times by 30-40% while keeping immediate deflection within limits. Practical field workflows designed for the rapid tourist resort market in the high-seismic zone of Bali are established to guide modern site management teams.

SECTION I: STRUCTURAL ANALYSIS AND ACCELERATION MECHANICS (English) 1. Introduction and Fast-Track Boundary Constraints In high-density commercial construction and rapid luxury residential developments, time-to-market serves as a critical financial constraint. Horizontal reinforced concrete framing elements, such as beams and slabs, typically dictate the critical path of the project schedule due to standard concrete curing timelines. Traditional timber formwork methods often extend cycle times because they require on-site cutting, manual assembly, and lengthy shoring periods until the concrete reaches its full design capacity. Accelerating this structural process requires specialized engineering interventions. Stripping formwork early exposes concrete elements to high early-stage dead loads, which can cause excessive immediate deflection ($\delta$), micro-cracking, or progressive structural failure if not calculated properly. In high-seismic tropical regions like Bali, fast-track construction must be executed with high precision. Early formwork removal requires a precise verification of structural concrete maturity, ensuring that beam-column connections maintain full shear and flexural capacity during early-stage dynamic loading conditions. 2. Analytical Formulation of Early Stripping and Maturity Mechanics The acceleration of beam formwork cycle times is governed by the structural development of the concrete's early-age compressive strength ($f'_{ct}$) and its modulus of elasticity ($E_{ct}$). Estimating this early strength development requires using the standard concrete maturity function based on time-temperature tracking parameters: $$M(t) = \sum \left[ (T_a - T_0) \cdot \Delta t \right]$$ Where: $M(t)$ = Maturity index of the active concrete matrix ($^\circ \text{C} \cdot \text{hours}$) $T_a$ = Average internal concrete temperature during the tracking interval $\Delta t$ ($^\circ \text{C}$) $T_0$ = Datum reference temperature, standardly fixed at $-10^\circ \text{C}$ $\Delta t$ = Specific operational time step or duration increments ($\text{hours}$) Once the concrete matrix achieves the target maturity index required for early formwork stripping, the beam section's capacity must be checked against structural limit states. The nominal flexural capacity ($M_n$) of the early-age beam section is calculated using the following structural relationship: $$M_u \leq \phi M_n = \phi \cdot A_s \cdot f_y \cdot \left( d - \frac{a}{2} \right)$$ Where the equivalent rectangular stress block depth ($a$) at early age is formulated as: $$a = \frac{A_s \cdot f_y}{0.85 \cdot f'_{ct} \cdot b}$$ $M_u$ = Factored ultimate bending moment applied during early construction stages ($kN \cdot m$) $\phi$ = Tension-controlled strength reduction factor ($0.90$) $A_s$ = Area of non-prestressed longitudinal tension steel reinforcement ($mm^2$) $f_y$ = Specified yield strength of structural steel reinforcement ($MPa$) $f'_{ct}$ = Compressive strength of concrete measured at the exact hour of early stripping ($MPa$) $b$ = Width of the structural concrete beam base cross-section ($mm$) $d$ = Effective cross-sectional depth of longitudinal reinforcement ($mm$) To safely accelerate formwork stripping, a drop-head shoring system must be implemented. This structural system allows the horizontal beam side panels and soffit deck to be dismantled early while the main vertical shores remain under load, preventing mid-span deflection. The maximum allowable unbraced span ($L_{max}$) between these temporary shores is limited by immediate elastic deflection rules: $$\delta \leq \delta_{allow} = \frac{L}{480}$$ $$L_{max} = \sqrt[3]{\frac{384 \cdot E_{ct} \cdot I \cdot \delta_{allow}}{5 \cdot w_{construction}}}$$ Where: $E_{ct}$ = Early-age modulus of elasticity of the setting concrete ($MPa$) $I$ = Gross second moment of inertia of the concrete structural beam profile ($mm^4$) $w_{construction}$ = Unfactored vertical construction dead load, including the structural concrete mass and multi-story staging allocations ($kN/m$) 3.

Metodologi Lapangan dan Penerapan Sistem Cepat Berstandar Internasional Eksekusi pekerjaan konstruksi penahan horizontal balok dengan metode cepat wajib didasarkan pada perhitungan mekanika struktural beton usia dini ( early-age concrete mechanics ), bukan sekadar mengejar target waktu tanpa parameter teknis yang jelas. Berdasarkan regulasi teknis nasional SNI 2847:2019 dan standar internasional ACI 347R, percepatan pelepasan cetakan penahan beton tanpa kalkulasi yang valid berisiko tinggi memicu lendutan berlebih ( excessive deflection ) dan keretakan struktural dini. Prosedur pelaksanaan metode cepat dimulai dengan beralih dari bekisting kayu konvensional ke Sistem Bekisting Modular Aluminium (Alu-Form) yang dikombinasikan dengan teknologi penopang kepala-lepas ( drop-head shoring ). Sistem modular ini dirancang presisi dengan tingkat kekakuan material yang tinggi, sehingga proses perakitan dan pembongkaran di lapangan dapat diselesaikan 50% lebih cepat dibandingkan metode kayu tradisional. Untuk mendukung percepatan waktu bongkar, campuran beton wajib dimodifikasi menggunakan formula High-Early-Strength Concrete (HESC) atau penambahan aditif accelerator generasi terbaru. Target kuat tekan beton saat pembongkaran panel samping balok wajib dievaluasi secara akurat melalui pengujian sampel silinder di lapangan atau pemantauan digital berbasis indeks kematangan beton ( concrete maturity sensor ). Ketika beton mencapai kuat tekan dini ($f'_{ct}$) minimal 70% dari kuat tekan desain ($f'_c$), panel bekisting samping balok dapat dilepas dalam waktu 24–36 jam pasca-pengecoran untuk dipindahkan ke lantai di atasnya. Namun, sistem penopang vertikal utama ( re-shoring ) pada bagian bawah soffit balok wajib dipertahankan tetap memikul beban gravitasi hingga beton mencapai kapasitas penuh 28 hari, guna menjaga balok horizontal tetap lurus sempurna tanpa risiko retak susut plastik ( plastic shrinkage cracking ). 5.
