It is a Great Britain occupational-safety duty and does not approve a structure, license a trade, replace a project-specific method statement or apply outside Great Britain. - govuk-building-regulations-approval: UK Government (GOV.UK) — Building regulations approval: When you need approval (Living GOV.UK service page; read 2026-09-26) - https://www.gov.uk/building-regulations-approval - Scope: Official GOV.UK service page on building regulations approval. It states that you must check whether you need approval before you construct or change buildings in certain ways; that building regulations approval is different from planning permission and that you might need both; that the Building Regulations 2010 cover the construction and extension of buildings; and that approval may also be needed for many alteration projects, with examples including replacing fuse boxes and connected electrics, changing electrics near a bath or shower, putting in a fixed air-conditioning system, replacing windows and doors, replacing roof coverings on pitched and flat roofs, and installing or replacing a heating system. It adds that works not listed could still need approval or follow special rules, that you do not need to obtain approval yourself if you use someone registered with a competent person scheme, and that readers should find out about the separate rules in Scotland and Northern Ireland. It is an England-facing process service page: it does not decide whether a specific pergola, terrace or balcony project needs approval, name the applicable edition or amendments, or transfer to another jurisdiction. - cslb-contractor-license-check: California Contractors State License Board — Check a contractor license or home-improvement salesperson registration (Living official register; checked 2026-08-17) - https://www.cslb.ca.gov/OnlineServices/CheckLicenseII/CheckLicense.aspx - Scope: California's official lookup for contractor identity, licence status and disclosed complaint information.

It directs assessment toward actual construction characteristics, purpose and functional properties, and separately distinguishes specified owner-built shelters subject to supervision or professional qualification from shelters requiring a construction contractor and site manager; its renewable-energy small-structure examples require contractor delivery under the stated professional management. This is Czech methodological context, not a universal definition, project classification, permit outcome or substitute for current planning, fire and local checks. - slovakia-building-act-2025: Slov-Lex — Ministry of Justice of the Slovak Republic — 25/2025 Z. z.

That classification does not by itself establish a general right to self-build or decide notification, project review, planning, fire-safety, local requirements or whether a product sold as a pergola fits that category. ### Review questions 1. Are the principal statements technically accurate within the stated scope? 2. Do the cited organizations, documents, editions and source-scope notes support the article context without overreach? 3. Are jurisdiction, configuration and project-specific qualifications sufficiently explicit? 4. Are any safety, accessibility, durability or professional-responsibility boundaries missing? 5. Do the English and Simplified Chinese versions preserve the same material meaning and risk qualifications? ### Completion route - Reviewer workbench: https://pergola.wiki/reviewer-workbench/ - Review protocol: https://pergola.wiki/review-protocol/ Boundary: This is a pre-review evidence packet, not proof of correctness, endorsement, certification, authorship or completed independent review.

It states that it does not apply to wire, pipe, tube or steel sheet galvanized on specialized or continuous lines, or to steel less than 22 gage (0.0299 in. [0.76 mm]) thick, and that the galvanizing of hardware items to be centrifuged or otherwise handled to remove excess zinc — such as bolts and similar threaded fasteners, castings and rolled, pressed and forged items — shall be in accordance with Specification A153/A153M. It sets coating requirements for the products in its scope: it does not assign a steel grade, a structural capacity, a service life, an atmosphere corrosivity category or a project approval, and it states that its inch-pound and SI unit systems are not exact equivalents. - astm-a153: ASTM International — ASTM A153/A153M-23 — Standard Specification for Zinc Coating (Hot-Dip) on Iron and Steel Hardware (2023 edition, last updated 16 May 2023; public abstract read 2026-09-25) - https://www.astm.org/a0153_a0153m-23.html - Scope: Public abstract of the current ASTM specification for hot-dip zinc coatings on iron and steel hardware.

It explains that articles to be galvanized are immersed into and withdrawn from a bath of molten zinc heated to about 450 °C, that design and fabrication must therefore allow access and drainage of molten zinc, that holes present for other purposes may fulfil the venting and draining requirement where they are adequate and that extra holes may otherwise be necessary, that with hollow sections or internal compartments galvanizing the internal surfaces eliminates the danger of hidden corrosion occurring in service, and that where a design includes sealed hollow sections, guidance on correct venting and drainage must be incorporated. Its fabrication notes state that external stiffeners, welded gussets and webs should have their corners cropped, with as large a gap as structural strength allows and a radius where welding runs around the edge. It is industry process and detailing guidance: it does not set a vent or drain hole size, position or number, a member capacity, a coating class, a durability class or a project approval, and it is not a structural design code. - aga-galvanic-corrosion: American Galvanizers Association — Galvanic corrosion and the galvanic cell (Industry education page, last updated April 2022; read 2026-09-25) - https://galvanizeit.org/corrosion/corrosion-process/galvanic-corrosion - Scope: Industry association education page explaining the galvanic corrosion mechanism. It describes two primary types of galvanic cell — the bi-metallic couple, which it compares to a battery consisting of two dissimilar metals immersed in an electrolyte solution with an external conductive path, and the concentration cell, in which anode and cathode are the same metal or alloy and the driving force comes from a difference in concentration across the surfaces — and lists the four elements it states are necessary for corrosion to occur in a galvanic cell: an anode, where the galvanic reactions generate electrons and corrosion occurs; a cathode, which receives electrons and is protected from corrosion; an electrolyte, the conductor through which current is carried; and a return current path, the metallic pathway connecting anode to cathode, often the underlying metal substrate. It states that all four are necessary, that removing any one of them stops the current flow so that galvanic corrosion does not occur, that substituting a different metal for the anode or cathode may reverse the current and move the corrosion to the other electrode, and that the galvanic series lists metals and alloys in decreasing order of electrical activity. It explains a mechanism only: it gives no corrosion rate, no coating or isolation specification, no fastener rule, no service life and no project approval, and it is not a design code. ### Review questions 1.

Its scope covers zinc coating by the hot-dip process on iron and steel products made from rolled, pressed and forged shapes, castings, plates, bars and strips, and it covers both unfabricated products and fabricated products such as assembled steel products, structural steel fabrications and large tubes already bent or welded before galvanizing. It states that it does not apply to wire, pipe, tube or steel sheet galvanized on specialized or continuous lines, or to steel less than 22 gage (0.0299 in. [0.76 mm]) thick, and that the galvanizing of hardware items to be centrifuged or otherwise handled to remove excess zinc — such as bolts and similar threaded fasteners, castings and rolled, pressed and forged items — shall be in accordance with Specification A153/A153M. It sets coating requirements for the products in its scope: it does not assign a steel grade, a structural capacity, a service life, an atmosphere corrosivity category or a project approval, and it states that its inch-pound and SI unit systems are not exact equivalents. - astm-a153: ASTM International — ASTM A153/A153M-23 — Standard Specification for Zinc Coating (Hot-Dip) on Iron and Steel Hardware (2023 edition, last updated 16 May 2023; public abstract read 2026-09-25) - https://www.astm.org/a0153_a0153m-23.html - Scope: Public abstract of the current ASTM specification for hot-dip zinc coatings on iron and steel hardware. It states that the specification covers zinc coatings applied by the hot-dip process on iron and steel hardware, that the process forms layers of zinc/iron alloy adhering to the steel surface, that it applies to hardware items of Classes A, B, C and D, that the thickness or weight/mass of the zinc coating shall conform to specified values for the various classes of materials, and that coated articles shall be free from uncoated areas, blisters, flux deposits, dross inclusions and other defects, the coating being smooth and reasonably uniform in thickness. It also describes tests for minimum coating weight or thickness, finish and appearance, and embrittlement. It is a coating specification for hardware items: it does not set the substrate's grade, the connection design, the site exposure, a service life or a project approval. - ga-design-galvanizing: Galvanizers Association (UK and Ireland) — Design detailing — guidance for articles to be hot dip galvanized (Industry association guidance page; read 2026-09-25) - https://www.galvanizing.org.uk/galvanizing-process/design/ - Scope: Technical guidance page from the Galvanizers Association, the hot-dip galvanizing industry association for the United Kingdom and Ireland. It explains that articles to be galvanized are immersed into and withdrawn from a bath of molten zinc heated to about 450 °C, that design and fabrication must therefore allow access and drainage of molten zinc, that holes present for other purposes may fulfil the venting and draining requirement where they are adequate and that extra holes may otherwise be necessary, that with hollow sections or internal compartments galvanizing the internal surfaces eliminates the danger of hidden corrosion occurring in service, and that where a design includes sealed hollow sections, guidance on correct venting and drainage must be incorporated. Its fabrication notes state that external stiffeners, welded gussets and webs should have their corners cropped, with as large a gap as structural strength allows and a radius where welding runs around the edge. It is industry process and detailing guidance: it does not set a vent or drain hole size, position or number, a member capacity, a coating class, a durability class or a project approval, and it is not a structural design code. - aga-galvanic-corrosion: American Galvanizers Association — Galvanic corrosion and the galvanic cell (Industry education page, last updated April 2022; read 2026-09-25) - https://galvanizeit.org/corrosion/corrosion-process/galvanic-corrosion - Scope: Industry association education page explaining the galvanic corrosion mechanism. It describes two primary types of galvanic cell — the bi-metallic couple, which it compares to a battery consisting of two dissimilar metals immersed in an electrolyte solution with an external conductive path, and the concentration cell, in which anode and cathode are the same metal or alloy and the driving force comes from a difference in concentration across the surfaces — and lists the four elements it states are necessary for corrosion to occur in a galvanic cell: an anode, where the galvanic reactions generate electrons and corrosion occurs; a cathode, which receives electrons and is protected from corrosion; an electrolyte, the conductor through which current is carried; and a return current path, the metallic pathway connecting anode to cathode, often the underlying metal substrate. It states that all four are necessary, that removing any one of them stops the current flow so that galvanic corrosion does not occur, that substituting a different metal for the anode or cathode may reverse the current and move the corrosion to the other electrode, and that the galvanic series lists metals and alloys in decreasing order of electrical activity. It explains a mechanism only: it gives no corrosion rate, no coating or isolation specification, no fastener rule, no service life and no project approval, and it is not a design code. ### Review questions 1.

Its Details summary states that this edition covers protection from falling, collision and impact and includes designing staircases, ladders, ramps, guarding and vehicle barriers in and around all types of buildings; that since April 2023 the Building Safety Regulator has a duty under the Building Safety Act 2022 to keep under review the safety and standards of all buildings in England, including advising government on updates to the Approved Documents; and that this edition was updated by combining Approved Document N on glazing and some overlapping guidance from Approved Document M. Only the publication page and its summary were read in this check; the PDF was not machine-extracted, so no clause text, guard height, load value or dimension is attributed to it here. It is England-only technical guidance for one part of the building regulations: it does not decide whether a particular balcony, terrace, guard or pergola project needs approval, satisfies the requirement or is lawful anywhere else. - govuk-building-regulations-approval: UK Government (GOV.UK) — Building regulations approval: When you need approval (Living GOV.UK service page; read 2026-09-26) - https://www.gov.uk/building-regulations-approval - Scope: Official GOV.UK service page on building regulations approval. It states that you must check whether you need approval before you construct or change buildings in certain ways; that building regulations approval is different from planning permission and that you might need both; that the Building Regulations 2010 cover the construction and extension of buildings; and that approval may also be needed for many alteration projects, with examples including replacing fuse boxes and connected electrics, changing electrics near a bath or shower, putting in a fixed air-conditioning system, replacing windows and doors, replacing roof coverings on pitched and flat roofs, and installing or replacing a heating system. It adds that works not listed could still need approval or follow special rules, that you do not need to obtain approval yourself if you use someone registered with a competent person scheme, and that readers should find out about the separate rules in Scotland and Northern Ireland. It is an England-facing process service page: it does not decide whether a specific pergola, terrace or balcony project needs approval, name the applicable edition or amendments, or transfer to another jurisdiction. - legislation-uk-building-regs-2010-schedule-1: The National Archives — legislation.gov.uk — Building Regulations 2010, Schedule 1 — Requirements, Part K (protection from falling, collision and impact) (SI 2010/2214 revised text; read 2026-09-26) - https://www.legislation.gov.uk/uksi/2010/2214/schedule/1 - Scope: Official revised statutory text of the requirements in Schedule 1 to the Building Regulations 2010. In the part headed protection from falling it records that stairs, ladders and ramps used for movement between different levels must be safe and that requirement K1 applies only to stairs, ladders and ramps forming part of the building, and it states requirement K2: any stairs, ramps, floors and balconies and any roof to which people have access, and any light well, basement area or similar sunken area connected to a building, shall be provided with barriers where it is necessary to protect people in or about the building from falling, with a further requirement covering the safety of barriers. It is the functional requirement only: it states no barrier height, gap limit, load, spacing or product rule, and it does not determine whether a project needs approval, whether a specific guard or frame satisfies the requirement, or which national or amended version applies. Technical detail and dimensions sit in the approved documents and guidance for the relevant UK nation, and the applicable nation must be confirmed first. - scotland-technical-handbook-4-4-barriers: Scottish Government — Building standards technical handbook 2022: domestic — 4.4 Pedestrian protective barriers (Published 1 June 2022; section read 2026-09-26) - https://www.gov.scot/publications/building-standards-technical-handbook-2022-domestic/4-safety/4-4-pedestrian-protective-barriers/ - Scope: Official Scottish Government section of the domestic building standards technical handbook, which states that it provides guidance on achieving the standards set in the Building (Scotland) Regulations 2004 and applies to a building warrant submitted on or after 1 June 2022. Its mandatory Standard 4.4 requires every building to be designed and constructed so that every sudden change of level accessible in or around the building is guarded by pedestrian protective barriers, with a limitation where barriers would obstruct the use of the guarded area. The guidance states that a protective barrier should be provided at the edge of every floor, stair, ramp, landing, raised floor or other raised area to which people have access where the difference in level is 600 mm or more, and at any change in direction on a raised access or circulation route; that in and around domestic buildings openings in a barrier should prevent the passage of a 100 mm diameter sphere; that a barrier should be designed and constructed so that it cannot easily be climbed by young children, minimising potential hand and footholds; and that barriers and any wall, partition or fixed glazing accepted instead should resist loads calculated in accordance with BS EN 1991-1-1 and the associated PD 6688-1-1. Its height table gives 1,100 mm for locations other than the listed cases, with lower listed values including 900 mm to a gallery, landing or raised area within a dwelling. It is Scottish domestic guidance: it is not a pergola standard, does not approve a project, and its figures are not transferable to another jurisdiction, structure or occupancy without the applicable local rules. - ireland-planning-regulations-2001-class-3: Irish Statute Book — Planning and Development Regulations 2001 — Schedule 2, Part 1, Class 3 (S.I.
