1. Overview
Absolutely possible. Building integral relocation and elevation technology is a highly mature specialist engineering solution. In response to Indonesia’s frequent seasonal floods (Banjir) and land subsidence issues, this technique can completely preserve the original structure without demolition. It serves as a mainstream green solution for addressing low-lying terrain, flood prevention renovations, and coordinating with government urban planning (Pelebaran Jalan), aligning perfectly with Indonesia’s sustainable construction development direction.
II. In-depth Analysis of Different Building Types in Indonesia
⑴、Brick-concrete structures (Rumah Tembok / Bata Merah)
Applicability: Most common for 1-3 story residential buildings in Indonesia.
Technical details: For typical single or double-story red brick houses, we first perform structural underpinning (Grouting & Ring Balk reinforcement) to transform scattered brick walls into a rigid monolithic system. Combined with precise hydraulic synchronous lifting systems, even in areas with softer soil (such as northern Jakarta or parts of Kalimantan), we ensure crack-free elevation of buildings.
⑵、Frame structure building (Struktur Beton Bertulang)
Applicability: Commercial office buildings, modern residences, and multi-story structures.
Technical Advantages: The frame structure integrates beams and columns, ensuring excellent overall integrity. In Indonesia’s high seismic zones (Seismic Zone), our professional underpinning techniques enable PLC computer-synchronized lifting without compromising the original seismic structure, guaranteeing utmost safety.
⑶、Traditional Wooden Houses and Stilt Houses (Rumah Panggung / Rumah Kayu)
Applicability: Traditional architectural styles, resorts, and rural areas.
Optimization Suggestions: Wooden structures are lightweight, making them the easiest type for lifting and relocation. Many old houses suffer from foundation corrosion or waterlogging due to raised road levels. Comprehensive lifting and foundation reinforcement (Pondasi) not only resolve waterlogging issues during the rainy season but also correct structural tilting, revitalizing old houses.
⑷、Cultural Heritage and Historic Buildings (Bangunan Cagar Budaya)
Policy Compliance: According to Law No. 11 of 2010 (Concerning Cultural Heritage), the protection of cultural relics is strictly prohibited from being compromised.
Core Solution: Relocation in its entirety is the sole method to resolve conflicts between municipal road construction or river management and cultural heritage preservation. Utilizing minimally invasive underpinning techniques, we accomplish the relocation without disturbing the main structure or damaging original carvings and historical decorations. This approach holds significant application value for maintaining historic buildings in Indonesia’s Old Town (Kota Tua).
III. Legal and Industry Recommendations
Legal Compliance: Before conducting any overall lifting or relocation, property owners are advised to consult with the local DPMPTSP (One-Stop Integrated Service Department). Changes in building position or height may require modifications to the PBG (Building Permit) or reassessment of the SLF (Functionality Certificate).
Seismic Design: The new foundation after lifting must comply with the latest earthquake-resistant standards SNI 1726:2019.
Extreme cases: This type of project is not recommended only when the building has been deemed a “dangerous structure” (Bangunan Gagal Bangunan) and the load-bearing capacity of the main structure is completely lost (such as severe concrete cracking or steel reinforcement corrosion).
Four、Summary:
As long as a building has utility or cultural value, regardless of its structural type, in Indonesia’s complex geographical and climatic conditions, overall relocation and elevation are a more economical, faster, and environmentally friendly optimized choice than demolition and reconstruction.
