I. Overview
Absolutely not. The core principle of formal and professional shifting and lifting construction is “zero structural damage.” Through advanced integral underpinning technology, the building remains extremely stable during construction, with walls, floors, beams, and columns fully capable of withstanding minor construction forces. The safety of this specialized engineering has been proven in countless high-difficulty cases. Risks only arise when there is a lack of qualifications, failure to perform structural underpinning, or reckless operations. %% In Indonesia’s rainy and geologically complex environment, we ensure 100% no-collapse through the following three layers of protection: %% Underpinning / Rigid Box: Before construction, we first pour a closed reinforced concrete ring beam (Ring Balk) at the base of the building. This acts like a custom-made “rigid foundation,” evenly transferring the originally dispersed weight to the ring beam. At this point, the entire building is effectively placed inside a sturdy safe, bearing forces as a whole rather than relying on individual beams or columns. %% PLC Computer Synchronized Lifting System: We do not rely on manual operation. All jacks are synchronized and controlled by a computer, with errors maintained within 1.0mm – 2.0mm. This millimeter-level precision ensures the building moves up and down uniformly at all points, preventing any structural distortion or impact. %% Real-time Monitoring: High-precision sensors are deployed on-site to continuously track displacement, tilt angles, and force variations. If data deviates from preset values, the system automatically locks and halts operations, technically eliminating any possibility of collapse.
II. Will It Collapse? (100% Safety Bottom Line)
Standard construction: Virtually no new cracks appear, and the structure remains unchanged.
Underpinning / Rigid Box: Before construction begins, we first pour a closed-loop reinforced concrete ring beam (Ring Balk) beneath the house. This is equivalent to creating a “rigid base” tailored for the building, evenly transferring the originally dispersed gravitational loads to the ring beam. At this point, the entire house is like being placed into a sturdy safe, bearing forces as a whole without relying on individual beams or columns for support.
PLC Computerized Synchronous Lifting System: We do not rely on manual operation. All jacks are controlled synchronously by computer, with errors maintained within 1.0mm – 2.0mm. This millimeter-level precision ensures that all points of the house remain synchronized during lifting, preventing any structural distortion or impact.
Real-time Monitoring: High-precision sensors are deployed on-site to continuously monitor displacement, tilt angles, and stress changes. If data deviates from preset values, the system automatically locks and stops, completely eliminating the possibility of collapse from a technical process standpoint.
3. Will it crack or deform?
Standardized Construction: Virtually no new cracks develop, and the structure remains in its original condition.
Steady Advancement: The lifting or shifting process is extremely slow and smooth, with precisely calculated force application points to avoid stress concentration.
Regarding Old Cracks: Many old houses already have cracks due to foundation settlement (Ambles). During construction, these existing cracks may show slight reactions, but this is the manifestation of pre-existing conditions rather than new damage. After construction, through synchronous correction, these cracks often achieve better closure and repair.
Protection of Decorations: Floors, beams, columns, and door/window frames are not subjected to compression during construction. The wall plaster layers and ceilings (Plafon) remain intact.
4. Can the walls, floors, beams, and columns withstand construction loads and vibrations?
No problem at all. The construction intensity is far below the structural design limit.
Scientific force application: The shifting doesn’t pull on the walls but lifts the bottom beams instead. The force is evenly distributed across the entire building’s “base plate.”
Extremely low vibration: The lifting and shifting process is a form of “static operation,” generating vibrations even smaller than those caused by a heavy truck (Truk Besar) passing by the roadside—far below the level that could damage brick-concrete or frame structures.
Safety Margin: Even the common brick houses frequently seen in Indonesia have sufficient safety factors in their beams, columns, and walls. Under stable loading conditions, the structural redundancy is more than adequate.
V. Special Compliance Guarantees Tailored for Indonesia’s Environment
When implementing such projects, the following industry standards must be observed:
Seismic Review: According to SNI 1726:2019, we ensure that the temporary support system during underpinning reinforcement can withstand potential seismic impacts during construction.
Seasonal Protection: For Indonesia’s rainy season (Musim Hujan), we will particularly strengthen drainage and slope support for foundation pits to prevent support point displacement caused by rainwater saturation.
Professional Qualifications (Legal Check): The owner should verify whether the contractor holds an SBU (Sertifikat Badan Usaha) certificate related to special engineering in Indonesia, as this is the legal guarantee for safe construction.
VI. Summary
House shifting and lifting is a “gentle” precision procedure, not a violent forced pull. As long as a professional team employs synchronous jacking and structural underpinning techniques, your house will maintain its structural integrity throughout—no collapse, no cracks, no deformation. It’s an engineering solution you can fully trust.
Expert Tip (for Indonesian clients):
Due to the high groundwater levels in some areas of Indonesia, we implement a professional dewatering system during construction to ensure that the support foundation operates on dry and firm soil, thereby providing foolproof construction stability.
