I. Overview
Absolutely not. In formal and professional shifting and turning construction, the house is not “yanked or dragged” but is placed on a stable rigid bracket system for overall translation or rotation. In Indonesia, for complex soil conditions and frequent microseismic environments, the computer-synchronized control technology we employ ensures millimeter-level accuracy, fundamentally eliminating the conditions that could generate “twisting” or “pulling” forces from a physical mechanism perspective.
2. Why can professional construction ensure no cracking?
⑴、Rigid Box Effect
Before shifting or turning, we must complete a closed reinforced concrete ring beam (Ring Balk) around the base of the house. This is equivalent to creating a sturdy “base support” for the house, integrating the originally dispersed walls, beams, columns, and floors into an inseparable whole.
⑵、PLC Computer Synchronized Monitoring System
This is the core of preventing cracking. With significant geological variations in Indonesia, traditional manual jacking often leads to uneven lifting—faster on one side and slower on the other. Our PLC system synchronizes the control of dozens of hydraulic support points, keeping displacement errors within 1.0mm to 2.0mm. The building remains perfectly level at all times, eliminating any “torsional shear forces” caused by uneven stress distribution.
⑶、The Logic of Scientific Steering
Central Disc Rotation (Rotasi Pusat): Similar to a train turntable, it enables smooth rotation around a central point with a clearly defined force axis.
Tangent Track Steering: For situations requiring both shifting and turning simultaneously, we employ multi-segment tangent tracks to gradually adjust the angle, ensuring the building maintains force equilibrium during dynamic movement.
3. Under what extreme circumstances would cracking occur?
Only in construction practices that completely violate Indonesia’s Construction Services Law (UU Jasa Konstruksi) would the following occur:
Omitted Underpinning: Cutting costs by lifting brick walls directly without installing transfer beams, leading to localized stress collapse.
Manual Jacking: Relies on manual operation of jacks with inconsistent speed, artificially creating torque.
Disregarding soil conditions: During the rainy season in Indonesia (Musim Hujan), the foundation pit was relocated without proper protection, leading to uneven settlement of the track foundation, which in turn caused cracks in the building.
IV. Authentic Assessment of “Old Cracks” vs. “New Cracks”
New structural cracks: As long as our professional construction plan is followed, no new structural cracks will appear in the main beams, columns, or floor slabs.
Existing hairline cracks (Rambut Retak): If your house already has minor cracks due to foundation settlement or temperature variations, slight opening and closing may occur during the relocation process. This represents the release of pre-existing structural vulnerabilities rather than new damage. After final positioning and reinforcement, we will perform professional structural repairs and aesthetic enhancements.
V. Compliance Reminders Specific to the Indonesian Context
Seismic stability: The new orientation after rotation must be re-evaluated against the lateral force distribution specified in Indonesian SNI 1726:2019 earthquake standards, ensuring the seismic design of the new foundation perfectly aligns with the building’s revised orientation.
Professional Qualification Certification: In Indonesia, companies undertaking such high-difficulty projects must possess an SBU (Construction Service License) and have professional engineers (SKA) specialized in special engineering to sign off on the work.
VI. Summary
House shifting and reorientation is a meticulous precision engineering process, far from being a violent mechanical pulling. With the application of integral underpinning and PLC synchronization technology, your house will remain as stable as sitting on a first-class sofa, completely free from concerns about twisting or cracking.
Expert tip:
For Indonesia’s soft soil layers, we conduct foundation load tests (Proof Loading) before laying the shifting tracks to ensure the track foundation can withstand the dynamic loads during house relocation, eliminating the risk of cracking caused by uneven ground from the very foundation level.
