The AS 4687:2022 compliance standards represent a major overhaul of Australian temporary fencing requirements, introducing critical safety improvements including dual-sided wind testing, a three-tiered risk classification system, and comprehensive documentation protocols. This complete guide walks construction managers through the complex implementation process, from calculating site-specific wind loads to establishing proper inspection schedules, helping teams navigate the most significant changes to temporary fencing regulations in over a decade while maintaining project efficiency and legal compliance.
Introduction: Navigating the New Standard
The 2022 AS 4687 compliance update hits the Australian construction industry like a freight train – it’s the biggest shake-up to temporary fencing rules we’ve seen in more than a decade, and most teams are scrambling to keep up.
This overhaul tackles real safety problems that have plagued construction sites for years, but it also throws some serious engineering curveballs that many crews find tough to handle. We’re not just going to recite the rule book here – this guide gives you the actual playbook that top Australian firms use to nail AS 4687 compliance while keeping their projects moving. You’ll get the straight story on wind loading calculations, dual-sided anti-overturning testing, and all the paperwork that makes compliance officers happy.
Understanding the AS 4687:2022 Framework Structure
Instead of one confusing document, the new standard breaks everything down into four connected parts that actually make sense when you see how they work together.
The Four-Part Standard Architecture
The 2022 version completely reorganizes how Australian temporary fence standards work. Think of it like a toolkit where each part handles a specific job, but they all need to work together.
Part 1: General Requirements – This is your foundation document. It sets up the core concepts, definitions, and compliance pathways that apply to every type of temporary barrier you’ll encounter. For a detailed breakdown, see this guide on Understanding AS4687.1:2022 Standards for Temporary Fencing.
Part 2: Temporary Fencing & Pedestrian Barriers – Here’s where you’ll find the nuts and bolts for standard mesh fencing and crowd control setups, including beefed-up anti-climb specifications that actually work.
Part 3: Temporary Hoardings – This section handles solid barriers with a heavy focus on wind load calculations and public safety considerations that can make or break your project approval.
Part 4: Temporary Swimming Pool Fencing – Special safety requirements for pool barriers during construction and renovation, now integrated with AS 1926.1:2024.
Key Changes from AS 4687:2007
The 2022 update brings several game-changing requirements that demand new approaches to temporary fencing compliance implementation.
Dual-sided testing: Your fencing now needs to handle wind pressure from both directions, fixing a major weakness where wind from the “wrong” side could topple barriers.
Three-tiered classification system: Stability Class, Importance Level 1, and Importance Level 2 replace the old one-size-fits-all approach that never quite fit any situation perfectly.
Integrated wind loading methodology: Cleaner calculations based on AS 1170.2 principles, with lookup tables designed specifically for temporary structures.
Explicit shade cloth requirements: Clear engineering guidelines for attachments that dramatically increase wind loading – no more guessing games.
Formalized documentation protocols: Mandatory certification, testing records, and installation documentation that compliance officers can actually verify.
Compliance Pathways: Testing vs. Engineering Analysis
You’ve got two solid options to prove your fencing meets the new requirements: put it through physical testing or run the numbers with engineering analysis – both paths work, but they require different approaches.
Physical Testing Protocol Requirements
For manufacturers and suppliers, the standard lays out specific tests that prove your gear can handle real-world conditions.
Climbing Resistance Test: A 65kg load applied for 3 minutes with zero structural failure or permanent deformation.
Mesh Aperture Verification: Maximum 75mm opening to prevent foothold formation, with standardized measurement procedures.
Impact Resistance Testing: ~37kg weight delivered at 150 J impact energy to simulate vehicle or equipment collision.
Wind/Overturning Testing: Dual-sided anti-overturning testing from both fence faces with precise load measurement protocols.
Engineering Analysis Alternative
The 2022 standard officially recognizes engineering design analysis as a valid alternative to physical testing. This pathway requires:
- Structural calculations demonstrating compliance with all loading requirements
- Material specifications meeting Australian standards for corrosion resistance and strength
- Site-specific wind loading analysis using the standard’s methodology
- Professional certification by a qualified structural engineer

Wind Loading Calculations: A Practical Implementation Guide
Getting the wind load right for your specific site comes down to a straightforward four-step process that takes the guesswork out of the standard’s methodology.
Determining Design Wind Speed
The revised standard uses a systematic but practical approach to determine site-specific wind requirements for temporary fence installation and maintenance Australia projects.
Step 1: Establish Importance Level
– Stability Class (54 km/h): Ultra-low risk applications only
– Importance Level 1 (37 m/s): Low risk to people, minor consequences if failure occurs
– Importance Level 2 (39 m/s): Medium risk to people, significant consequences if failure occurs
Step 2: Assess Terrain Category
– TC1 (Open terrain/water): Maximum wind loading conditions
– TC2-TC4 (Increasing obstructions): Progressively reduced wind speeds
– Assessment radius extends 500m from the installation site
Step 3: Evaluate Shielding Conditions
– Full Shielding (HS): Ms = 0.8 (10+ house-sized obstructions per hectare)
– Medium Shielding (MS): Ms = 0.9 (3-10 obstructions per hectare)
– No Shielding (NS): Ms = 1.0 (Fewer than 3 obstructions per hectare)
Step 4: Calculate Topography Effects
– Multipliers ranging from 1.0 (flat terrain) to 1.7 (steep slopes/cliff faces)
– Standardized measurement procedures for slope assessment
Wind Load Configuration Tables
| Importance Level | Terrain Category | Shielding | Topography | Design Wind Speed (m/s) | Required Bracing |
|---|---|---|---|---|---|
| Stability Class | TC2 | MS | 1.0 | 28 | Standard |
| Importance Level 1 | TC1 | NS | 1.15 | 34 | Enhanced |
| Importance Level 2 | TC1 | NS | 1.25 | 38 | Heavy Duty |

Integration with Other Standards and Regulations
AS 4687:2022 doesn’t exist in a vacuum – it works alongside WHS regulations and local council requirements that can trip up even experienced teams if you don’t know how they connect.
The standard integrates with WHS regulations through duty of care requirements, safe work system implementations, and risk assessment methodologies that compliance officers expect to see documented. It also establishes specific application requirements, including minimum 1.8m height for construction site fencing and elevated 2.4m height requirements for high-risk areas. Many local councils impose additional requirements such as permit obligations, aesthetic considerations for urban areas, and specialized configurations for heritage sites that you must address alongside the base standard. For a comprehensive overview of these temporary fencing legal requirements, consult industry experts.
Implementation Challenges and Solutions
Most teams hit the same roadblocks: incomplete documentation and botched wind load calculations – but these problems have straightforward solutions once you know what to watch for.
Common challenges include documentation gaps like missing supplier test certificates or inadequate site-specific engineering analysis. Technical implementation errors such as incorrect wind load calculations or insufficient bracing configurations also plague many projects. You can overcome these challenges through early planning, supplier qualification processes that verify compliance documentation, and comprehensive training programs for installation and inspection teams on the new protocols. A thorough Australia temporary fencing buying guide can help you navigate these common pitfalls.
