1.One<\/b><\/strong>Overview<\/b><\/strong><\/span><\/span><\/p>\n

Not only will it not decrease, but it will significantly improve. Proper relocation and lifting projects inherently serve as a process of deep “seismic reinforcement.” This technology transforms old, fragile building structures into rigid, integrated units and rebuilds foundations to meet modern seismic standards, making the house stronger and safer than before construction.<\/span><\/span><\/p>\n

2. Why doesn’t the structural strength decrease?<\/span><\/span><\/b><\/strong><\/p>\n

The core reason lies in the engineering logic of “reinforce first, then move”:<\/span><\/span><\/p>\n

Structural Underpinning (Struktur Perkuatan): Before relocation or lifting, a closed reinforced concrete underpinning beam system (Ring Balk\/Tie Beam) must be constructed beneath the house. This is equivalent to equipping the house with an “external skeleton,” binding the originally scattered walls and columns into a rigid box.<\/span><\/span><\/p>\n

Millimeter-level synchronization technology: Given Indonesia’s complex geological conditions, traditional manual lifting can easily damage the structure. We use a PLC computer-controlled synchronization system to keep lifting errors within 1.0mm \u2013 2.0mm. All force-bearing points of the house remain fully synchronized, ensuring no internal stress damage to the main beams, columns, or walls.<\/span><\/span><\/p>\n

High-performance material applications: In lifting and docking as well as foundation reconstruction, we utilize high-grade concrete (K-300 or above) and specialized reinforcement materials, whose strength typically exceeds that of the original materials found in older Indonesian buildings.<\/span><\/span><\/p>\n

III. Significant Enhancement of Seismic Resistance (Anti-Seismic Upgrade)<\/span><\/span><\/b><\/strong><\/p>\n

Indonesia is located in the Pacific Ring of Fire, making seismic resistance the lifeline of houses: %% Addressing seismic deficiencies: Many old brick-and-mortar houses (Rumah Bata) lack ring beams and structural columns. During the lifting and shifting process, we will reinforce the seismic structure according to the SNI 1726:2019 standard, upgrading “loosely assembled houses” into a system with complete seismic energy dissipation capabilities. %% Anti-Liquefaction Foundation Treatment: In earthquake-prone areas like Palu, soil liquefaction poses a significant threat. During foundation reconstruction, we will simultaneously reinforce the foundation or use micropiles, greatly enhancing the stability of the foundation during seismic activity. %% Reducing earthquake damage risks: Buildings strengthened as a whole can maintain “integral swaying” rather than “partial collapse” when subjected to seismic shear waves, significantly increasing the safety margin for evacuation. %% Regulatory compliance: Engineering designs must undergo seismic review by a licensed structural engineer (SIPT\/SKA) in Indonesia to ensure the modified structure fully complies with Indonesian National Standards (SNI).<\/span><\/span><\/p>\n

Ground Anti-Liquefaction Treatment (Anti-Liquefaction): In earthquake-prone areas like Palu, soil liquefaction poses a significant threat. During foundation reconstruction, we simultaneously implement ground reinforcement or micropile techniques (Micropile), greatly enhancing the stability of building foundations during seismic activity.<\/span><\/span><\/p>\n

Reducing Seismic Damage Risks: Buildings with overall structural reinforcement can maintain “integral swaying” rather than “partial collapse” when facing horizontal seismic wave impacts, significantly increasing safety margins for evacuation.<\/span><\/span><\/p>\n

IV. Legal and Professional Compliance Recommendations<\/span><\/span><\/b><\/strong><\/p>\n

Standard Compliance: Engineering designs must undergo seismic review by structural engineers with Indonesian professional qualifications (SIPT\/SKA), ensuring the retrofitted structures fully comply with Indonesian National Standards (SNI).<\/span><\/span><\/p>\n

Barbaric construction strictly prohibited: In the Indonesian market, there are some unqualified small workshops. Forcibly moving buildings without underpinning or synchronous jacking will destroy the seismic logic of the structure. Always choose a professional special company with SBU (Building Service License).<\/span><\/span><\/p>\n

Seismic zone adaptation: Our solutions are tailored based on the specific seismic intensity zoning of your property’s location (such as Jakarta, Sumatra, or Bali).<\/span><\/span><\/p>\n

V. Summary<\/span><\/span><\/b><\/strong><\/p>\n

Overall shifting and lifting is not a “loss project,” but rather a “safety upgrade project.” As long as it is carried out by a professional team, the completed house will undergo a “qualitative leap” in structural strength and seismic performance, giving you greater peace of mind when facing earthquakes and natural disasters.<\/span><\/span><\/p>\n

Expert Tips:<\/span><\/span><\/p>\n

Since some regions of Indonesia fall under high-humidity salt fog environments (coastal areas), we specifically reinforce the thickness of the steel reinforcement protective layer and apply anti-corrosion treatments during structural reinforcement to prevent corrosion from affecting long-term seismic resistance strength.<\/span><\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
