1.2 Building Safety Act 2022 (England) -- Major Reform

1.2 英格兰《2022年建筑安全法案》——重大改革

Following the 2017 Grenfell Tower fire, the UK enacted the Building Safety Act 2022 (BSA 2022). Key changes effective from 2023:
  • Building Safety Regulator (BSR) created within HSE -- regulates "occupation" + "construction" of Higher-Risk Buildings (HRB)
  • Higher-Risk Building (HRB) definition: ≥18 m height OR ≥7 storeys AND contains ≥2 residential units. Hospitals + care homes during design+construction. Some non-residential captured.
  • Three Gateways: Gateway 1 (planning -- fire statement); Gateway 2 (pre-construction -- BSR approval); Gateway 3 (occupation -- BSR approval)
  • Golden Thread of information -- digital, accessible, version-controlled, mandated for HRBs
  • Accountable Person + Principal Accountable Person -- duty holder regime for occupied HRB
  • Resident Engagement Strategy mandatory
  • Mandatory Occurrence Reporting (MOR) -- safety occurrences reported to BSR
  • Safety Case Report -- demonstrates HRB safety, regularly updated
  • New Homes Ombudsman -- consumer redress for new homes
2017年格伦费尔塔火灾后,英国颁布了**《2022年建筑安全法案》(BSA 2022)**。2023年起生效的核心变更包括:
  • 在HSE下设建筑安全监管局(BSR)——负责监管高风险建筑(HRB)的“使用”与“建造”阶段
  • 高风险建筑(HRB)定义:高度≥18米 或 ≥7层 且包含≥2个住宅单元。医院与护理院在设计和建造阶段也纳入范畴,部分非住宅建筑同样适用。
  • 三大网关:网关1(规划阶段——消防声明);网关2(施工前——BSR审批);网关3(投入使用——BSR审批)
  • 黄金线程(Golden Thread)信息:HRB必须建立数字化、可访问、版本受控的信息链
  • 责任人 + 主要责任人:已投入使用的HRB需建立职责持有人体系
  • 强制制定居民参与策略
  • 强制事件报告(MOR):安全事件需向BSR报告
  • 安全案例报告:证明HRB的安全性,需定期更新
  • 新住宅监察员:为新建住宅提供消费者权益救济渠道

2.2 Approved Documents Are Guidance

2.2 Approved Documents为指导性质

Critical concept: ADs are guidance -- they describe one way to comply. Alternative approaches are permitted if they meet the functional requirements of the Building Regulations. This enables performance-based fire engineering, etc.
核心概念:AD属于指导文件——仅描述了一种合规方式。若能满足《建筑法规》的功能要求,可采用替代方案。这为基于性能的消防工程等方法提供了空间。

2.3 Planning Permission vs Building Control

2.3 规划许可 vs 建筑监管

  • Planning Permission -- Local Planning Authority (LPA) under Town and Country Planning Act 1990; addresses use, scale, design, impact
  • Building Control -- compliance with Building Regulations 2010; addresses safety, performance, accessibility
  • These are SEPARATE consents; both usually required
  • Permitted Development Rights -- some works exempt from full planning permission
  • Prior Approval -- some PD requires LPA prior approval (e.g., change of use)
  • 规划许可:由地方规划局(LPA)依据《1990年城乡规划法》审批;关注用途、规模、设计、影响等
  • 建筑监管:核查是否符合2010年《建筑法规》;关注安全、性能、无障碍等
  • 两者是独立的审批程序,通常都需要办理
  • 许可开发权:部分工程无需申请完整规划许可
  • 预先核准:部分许可开发项目需获得LPA的预先核准(例如用途变更)

2.4 NPPF + Local Plans

2.4 NPPF + 地方规划

  • National Planning Policy Framework (NPPF) -- last revised 2024 -- sets national planning policy
  • Local Plans -- adopted by each LPA, set local planning policy
  • Neighbourhood Plans -- some localities have these too
  • London Plan 2021 -- spatial development strategy for Greater London by Mayor + GLA; significant policy weight in London applications

  • 国家规划政策框架(NPPF):最近修订于2024年——制定国家层面的规划政策
  • 地方规划:由各LPA通过,设定地方规划政策
  • 邻里规划:部分地区也会制定此类规划
  • 2021年伦敦规划:由市长 + 大伦敦管理局制定的大伦敦空间发展战略;在伦敦的规划申请中具有重要政策权重

7. Devolved Nations -- Quick Reference

7. 权力下放地区——快速参考

7.1 Scotland

7.1 苏格兰

Building (Scotland) Regulations 2004 (as amended) + Scottish Technical Handbooks (Domestic + Non-Domestic, updated 2023):
  • Section 1 Structure
  • Section 2 Fire (Scottish equivalent of AD-B; more stringent in some areas, e.g., sprinklers in homes ≥18 m + most flats above 11 m)
  • Section 3 Environment (resistance to noise/moisture/etc.)
  • Section 4 Safety (incl. accessibility)
  • Section 5 Noise
  • Section 6 Energy (parallel to AD-L)
  • Section 7 Sustainability
Process: Building Warrant before construction; Completion Certificate before occupation. Verifier (LA-appointed) checks compliance.
《2004年苏格兰建筑法规》(已修订) + 苏格兰技术手册(住宅 + 非住宅,2023版更新):
  • 第1节 结构
  • 第2节 消防(相当于英格兰的AD-B;部分领域更严格,例如≥18米住宅 + 11米以上多数公寓需设喷淋)
  • 第3节 环境(隔声/防潮等)
  • 第4节 安全(含无障碍)
  • 第5节 隔声
  • 第6节 能源(相当于AD-L)
  • 第7节 可持续性
流程:施工前需取得建筑许可(Building Warrant);投入使用前需取得竣工证书。由验证人(LA任命的建筑标准官员)核查合规性。

7.2 Wales

7.2 威尔士

Welsh Government issued its own Approved Documents from 2018+ with divergence from England. Key:
  • Welsh AD-L 2022 -- on parallel trajectory to FHS but distinct
  • Welsh AD-B -- post-Grenfell amendments aligned with England
  • Welsh Future Homes Standard -- under development
威尔士政府自2018年起发布自有版本的Approved Documents,与英格兰逐步出现差异。核心要点:
  • 威尔士版AD-L 2022——与未来住宅标准路径平行但有所不同
  • 威尔士版AD-B——格伦费尔火灾后的修订与英格兰一致
  • 威尔士未来住宅标准——正在制定中

7.3 Northern Ireland
