Major international infrastructure projects involving Chinese state contractors that experienced severe structural defects, collapses, or widespread quality controversies include the following prominent cases:Major International Shoddy Construction (Tofu-Dreg) CasesBangkok Government Office / Auditor General's New HeadquartersLocation: Bangkok, ThailandBuilder: China Railway No. 10 Engineering Group (中铁十局)Description: A 30-story government building under construction completely collapsed during a regional earthquake, standing out as the only major modern high-rise structure to suffer total collapse in the capital city, which triggered intense scrutiny over its construction standards.Coca Codo Sinclair Hydropower PlantLocation: EcuadorBuilder: Sinohydro (PowerChina)Cost/Financing: Financed via a $1.68 billion buyer's credit loan from China Eximbank.Description: Audits revealed thousands of structural fissures and micro-cracks in the steel machinery and water distribution components, leading to major disputes, government refusals to formally accept the facility, and subsequent international arbitration.Neelum–Jhelum Hydropower PlantLocation: PakistanBuilder: China Gezhouba GroupCost/Financing: Valued at hundreds of billions of local currency.Description: The 969-megawatt plant suffered severe structural damage and severe tailrace tunnel leakage due to geological and execution defects, forcing a total shutdown that resulted in massive regional energy deficits and costly remediation works.Karuma Hydro Power ProjectLocation: UgandaBuilder: China Water Electrical (CWE)Description: The project faced multi-year operational delays driven by recurring wall cracks, structural defects, and debris management failures that clogged power turbines.Sigiri BridgeLocation: KenyaBuilder: China Overseas Engineering Corporation (COVEC)Description: The bridge collapsed suddenly during its construction phase before official opening, causing injuries to construction personnel and triggering local inquiries into engineering oversight.Comparison of International Structural Defect CasesProject NameCountryMain ContractorPrimary Issue / FailureAuditor General HQThailandChina Railway No. 10Complete structural collapse during seismic eventCoca Codo SinclairEcuadorSinohydroThousands of stress cracks in machinery and pipesNeelum–JhelumPakistanGezhouba GroupTailrace tunnel failure and indefinite plant shutdownKaruma DamUgandaChina Water ElectricalSevere wall cracking and construction delaysSigiri BridgeKenyaCOVECMid-construction structural collapse
涉及中国国有承包商并出现严重结构缺陷、倒塌或引发广泛质量争议的重大国际基础设施项目，包括以下典型案例：重大国际“豆腐渣工程”案例——曼谷政府办公楼/审计长新总部（地点：泰国曼谷；承建商：中铁十局；概况：一栋在建的30层政府大楼在区域性地震中完全倒塌，成为首都唯一完全倒塌的现代化高层建筑，引发了对其施工标准的严厉审查）；科卡科多-辛克莱（Coca Codo Sinclair）水电站（地点：厄瓜多尔；承建商：中国水电/中国电建；成本/融资：由中国进出口银行提供16.8亿美元买方信贷；概况：审计发现钢制机械和配水部件存在数千处结构裂缝和微裂纹，导致重大争议、政府拒绝正式验收以及随后的国际仲裁）；尼鲁姆-杰赫勒姆（Neelum–Jhelum）水电站（地点：巴基斯坦；承建商：中国葛洲坝集团；成本/融资：价值数千亿当地货币；概况：这座装机容量969兆瓦的电站因地质和施工缺陷遭受严重结构损坏及尾水隧洞严重渗漏，被迫全面停运，导致区域能源严重短缺及高昂的修复工程）；卡鲁马（Karuma）水电项目（地点：乌干达；承建商：中国水利水电建设公司/CWE；概况：项目因墙体反复开裂、结构缺陷以及导致涡轮机堵塞的杂物管理不善等问题，面临长达数年的工期延误）；西吉里（Sigiri）大桥（地点：肯尼亚；承建商：中国海外工程有限责任公司/COVEC；概况：大桥在正式通车前的施工阶段突然倒塌，造成施工人员受伤，并引发了当地对工程监管问题的调查）。国际结构缺陷案例对比——项目名称（国家/主要承包商/主要问题或故障）：审计长总部（泰国/中铁十局/地震中结构完全倒塌）；科卡科多-辛克莱（厄瓜多尔/中国水电/机械和管道出现数千处应力裂缝）；尼鲁姆-杰赫勒姆（巴基斯坦/葛洲坝集团/尾水隧洞故障及电站无限期停运）；卡鲁马大坝（乌干达/中国水利水电建设公司/严重墙体开裂及工期延误）；西吉里大桥（肯尼亚/COVEC/施工期间结构倒塌）。
