What changed​

/website — now gated by email + PIN​

The shared-account directory (the page that lists corporate logins, default credentials, etc.) used to live on the homepage with a thin password gate. It has moved to /website and is now protected by the same allow-list + PIN flow we use for other internal tools.

If your work email is on the allow-list (@psecprojects.com.au or @saiyu.com.au are accepted by default), you can sign in. Anyone else gets a silent no-op — no error, no enumeration.

/url-shortener — new​

A new internal short-link tool at /url-shortener. Built specifically for distributing drawings to consultants and trades:

• Auto-generates short URLs at /s/<code> on the same domain.
• Records who created the link, click count, optional expiry, project code, reason for issue, and address.
• Auto-titles every link as YYYYMMDD-PROJECT-REASON in Sydney time (e.g. 20260429-K1-DA) — no manual naming.
• Default history view shows the last 14 days; the search box pulls from the full history.

Full reference: URL Shortener docs →

How to sign in​

Both pages use the same flow:

1. Open /website or /url-shortener.
2. Enter your work email. A 4-digit code arrives by email within seconds (codes expire in 10 minutes).
3. Enter the code. You're signed in for 8 hours.

One sign-in covers both pages. The session token is shared, so once you've signed in on /website you can navigate straight to /url-shortener without entering the code again, and vice versa.

If you don't receive the code:

• Double-check the email address — typos silently no-op to prevent guessing.
• Check spam (sender is noreply@saiyu.com.au).
• Ask GZ to confirm you're on the allow-list.

Why the change​

The old homepage password gate shipped credentials to every browser that loaded the page — a long-standing concern. The new flow keeps every credential on the server and only releases dashboard data after a verified sign-in. Adding the URL shortener was a chance to reuse the same auth instead of building a parallel one.

Feedback​

If something's broken, missing, or surprising — short codes that don't work, links that should appear in history but don't, sign-in loops, anything — reach out. Early days for the shortener especially.

Why We Restructured​

The previous framework was organised around legal duty-holder categories — PCBUs, Officers, Workers, Consultation — mirroring the layout of the WHS legislation itself. While accurate, this structure made it difficult to find what you needed in the field. If you were managing a welding operation or dealing with a silica dust concern, navigating through duty-holder definitions to find practical guidance wasn't useful.

The content was also becoming outdated. Rather than patching the old structure, we took the opportunity to rebuild it around the hazards and activities that construction safety professionals encounter day to day.

What's New — 8 Sections, Task-Oriented​

01 - Foundations​

The cross-cutting layer that underpins everything else — the 4-step risk management process, WHS consultation and coordination obligations, workplace environment and facilities requirements, first aid, and a glossary of key WHS terms and definitions.

02 - Construction Work​

Site-level application of WHS duties — HRCW thresholds, Safe Work Method Statements, principal contractor obligations, safe design of structures, demolition, excavation, and fall risks specific to housing construction.

03 - Falls and Heights​

Managing fall risks in non-housing contexts — multi-storey construction, maintenance work, and any situation where the 2-metre trigger applies outside the housing-specific rules.

04 - Plant and Electrical​

Plant registration, inspection cycles, operator competency requirements, and electrical risk management including testing and tagging obligations.

05 - Hot Work and Coatings​

Practical guidance for welding processes, abrasive blasting, and spray painting and powder coating — covering ventilation, PPE, fire risk, and health monitoring requirements.

06 - Hazardous Chemicals​

SDS management, labelling obligations under GHS, and risk controls for storing, handling, and disposing of hazardous chemicals on site.

07 - Dust and Asbestos​

Asbestos management plans, licensed removal requirements, respirable crystalline silica (RCS) controls, and air monitoring obligations for high-risk dust work.

08 - Manual Tasks, Noise & Confined Spaces​

Hazardous manual task identification and risk controls, noise exposure limits and hearing conservation programs, and confined space entry permit procedures including atmospheric testing and rescue planning.

SAIYU — Internal Documentation Update, 28 April 2026

Two new reference guides for the CSIM (Construction Site Information Management) system are now live in the wiki. If you manage site attendance or oversee worker inductions, these guides are for you.

What's New​

Worker Check-in & Check-out Guide​

The Guide_Worker Check-in & Check-out covers everything foremen need to know about managing daily site attendance — including all three checkout methods, visitor management, and the emergency muster function.

Key topics covered:

• Two ways workers check in: QR code scan or manual site selection
• Three checkout methods: self, foreman, and auto (6 PM daily)
• Handling visitor check-in and checkout
• Monitoring on-site personnel and running an Emergency Muster
• Common scenarios — forgotten PINs, wrong site, no induction

Managing Worker Inductions​

SAIYU — Internal Documentation Update, 11 April 2026

[!note] Update: Wednesday, 25 March 2026 NSW will adopt the new National Construction Code (NCC 2025) on 1 May 2027, providing the state’s building industry with more time to adjust to the new requirements so it can continue to deliver the homes the state needs.

National Construction Code 2025 Preview Draft vs NCC 2022 Deep Research Report — March 2026

Overview​

The NCC 2025 Volume One (Building Code of Australia — Class 2 to 9 buildings) introduces significant new provisions and updates across fire safety, water management, energy efficiency, accessibility, sanitary facilities, and electric vehicle infrastructure. The preview draft was released in February 2026, with earliest adoption expected from May 2026 (jurisdiction-dependent).

This report covers three areas:

1. What's NEW — provisions that did not exist in NCC 2022
2. What's UPDATED — existing provisions that have been revised
3. Why — the drivers and rationale behind the changes

1. What's NEW in NCC 2025​

1.1 EV Charging Infrastructure (Section J / Part J9)​

EV charging provisions were first introduced in NCC 2022 Amendment 2 (effective October 2023) for Class 2 buildings. NCC 2025 extends and refines these requirements across commercial building classes.

Important clarification: Class 2 (apartments) EV-ready requirements are not new in NCC 2025 — they were established under NCC 2022 Amendment 2. Building Ministers have paused further residential changes until mid-2029. NCC 2025's EV changes primarily affect commercial classes.

Requirements by building class:

Class 2 EV-ready technical specs (NCC 2022 Amd 2, continuing unchanged):

• 100% of car spaces must be EV-ready (infrastructure, not chargers)
• Dedicated EV distribution board separate from building systems
• Circuits supporting minimum 7 kW (32A) single-phase Type 2 chargers
• Minimum 12 kWh delivery between 11pm–7am daily
• Active conductors: minimum 6mm² cross-sectional area
• Max 50m cable run from distribution board to EVSE outlet
• 36mm DIN rail space per circuit for future metering
• One additional distribution board per 24 car spaces beyond 168 per storey
• Mandatory charging control system (load management)
• Compliance via DtS (Part J9D4) or Performance Solution (Clause A2G2)

Class 6 EV charging technical specs (NEW in NCC 2025):

• 10% of carpark spaces must have EV charging equipment
• Dedicated electrical distribution boards (EDBs) per storey, labelled for EV use
• Load management/charging control system required
• Separate sub-circuit metering for each EV charging device
• EDBs located no more than 10m from busduct (where busduct solution used)

1.2 Mandatory On-Site Solar (Section J — New DtS for Class 3–9)​

NCC 2025 introduces a new DtS requirement for mandatory on-site photovoltaic (PV) systems on commercial buildings.

• Class 6 buildings: Solar panels required on 100% of available roof space
• Exclusions: trafficable zones, plant spaces, shaded areas
• Class 7a buildings: Exempt from solar panel requirements
• Supports the "near zero operational greenhouse gas emissions" performance requirement

1.3 Water Management Framework (Part F1 — Restructured/New)​

NCC 2025 consolidates and expands water management into a unified framework under Part F1. This replaces the fragmented approach in NCC 2022 where waterproofing, weatherproofing, and water shedding were treated somewhat separately. Parts F1 and F3 have been merged into a single Part F1.

New framework structure:

Notable new/strengthened requirements:

• Minimum 1:80 gradient for water shedding on balconies, podiums, and accessible areas
• 70mm step-downs at door thresholds to external tiled areas
• Expanded scope to cover previously unregulated junctions and interfaces
• Performance-based pathways with clearer verification methods
• Class 7 and 8 buildings now included — previous waterproofing exemptions removed

1.4 All-Gender Sanitary Facilities (Part F4 — New Provision)​

NCC 2025 formally introduces provisions for all-gender (unisex) sanitary facilities in certain building types, reflecting contemporary approaches to inclusive design.

• Applicable to new Class 5, 6, and 9 buildings above certain thresholds
• Provisions allow all-gender facilities to count toward overall sanitary fixture requirements
• Privacy and safety design requirements included (full-height partitions, individual lockable compartments)

2. What's UPDATED in NCC 2025​

2.1 Fire Safety — Carpark Sprinklers & FRL (Section C)​

This is the most significant fire safety change in NCC 2025, driven by an Arup literature review of ~400 sources commissioned by ABCB.

Key details on EV fire considerations:

• EV battery fires produce significantly more smoke and toxic gases (including hydrogen fluoride) than conventional vehicles
• Require hours or days of firewater cooling for control
• Risk of re-ignition hours/days after initial extinguishment
• ABCB determined EVs should not be classified as "special hazards" — they are now common
• Queensland Fire's request to classify EVs under special hazard provisions (E1D17/E2D21) was not adopted

Rationale: The 1980s research underpinning the old open-deck exemptions did not account for modern vehicles (larger, more plastic content, EV batteries). The Arup review confirmed the updated risk profile.

2.2 Waterproofing & Water Shedding (Part F1)​

2.3 Condensation Management (Part F8)​

2.4 Women's Toilet Ratios (Part F4)​

Rationale: Evidence-based adjustment to reduce queue times at high-turnover venues.

2.5 Energy Efficiency (Section J)​

Rationale: Aligned with Australia's net zero 2050 target. Buildings account for ~25% of national energy consumption.

2.6 Structural Provisions (Section B)​

2.7 Accessibility (Part D — AS 1428.1 Update)​

2.8 Carpark Ventilation (Class 7a)​

3. Class-Specific Change Summary​

Class 7a — Carparks​

Class 6 — Retail / Shops / Cafes​

4. Reasons Behind the Changes​

4.1 Summary of Drivers​

4.2 Detailed Rationale​

Building Defect Prevention​

Water ingress and waterproofing failure remain the number one category of building defects in Australia. The consolidated water management framework directly targets this by mandating measurable gradients (1:80), specifying step-down dimensions (70mm), and expanding scope to balconies and terraces. The removal of Class 7/8 waterproofing exemptions acknowledges that carparks also suffer from water management issues.

Condensation and mould issues have increased as buildings become more airtight for energy efficiency. Extended Climate Zone 4-8 coverage and Class 4 vapour permeance requirements address these unintended consequences. Wall cladding changes (drained cavities in Zones 6-8) prevent moisture trapping behind facades.

Safety Modernisation​

The Arup literature review (~400 sources) confirmed that 1980s carpark fire research is obsolete. Modern vehicles are larger, contain more plastics, and include EV batteries that burn differently. The FRL increase from 60/60/60 to 120/120/120 for open-deck carparks and mandatory sprinklers for >40 spaces directly respond to this evidence.

Environmental & Climate Policy​

Australia's net zero 2050 commitment requires the building sector (~25% of national energy) to improve significantly. Mandatory solar panels for Class 6, tighter facade thermal performance (~44% reduction in solar admittance), and enhanced HVAC efficiency standards all contribute. The "near zero operational greenhouse gas emissions" performance requirement replaces the previous energy efficiency framing.

Social Equity & Inclusivity​

Updated women's toilet ratios for theatres/cinemas (1:1.8) are evidence-based. All-gender sanitary facilities reflect inclusive design principles. Updated accessibility standards (AS 1428.1:2021) incorporate a decade of research since the 2009 edition.

5. Implementation Timeline​

Key dates:

• February 2026: Preview draft published
• May 2026: Earliest jurisdiction adoption (ACT confirmed with 6-month transition)
• October 2025: Building Ministers agreed to pause residential changes until mid-2029
• Tasmania: Committed to freezing (not adopting) NCC 2025 EV changes
• NSW, VIC, QLD, SA, WA: Adoption dates not yet confirmed

What Changed​

Document Revision Codes​

The year has been shortened from four digits to two, and the separating dots between year and month are removed.

Examples:

Fieldwire Version Descriptions​

For plan version entries in Fieldwire, the date stamp format has also been shortened:

Examples:

Why We Made This Change​

Key reasons:

1. Fieldwire readability — shorter strings display fully without truncation in Fieldwire's version column.
2. Consistency — aligning both revision codes (YYMM) and fieldwire dates (YYMMDD) to the same two-digit year convention.

Scope of Change​

This update was applied globally across all documentation in the PSEC × SAIYU knowledge base, including:

• 01-policies — Filing Management, Revision Management, PSEC and SAIYU-specific policies
• 02-commercial — Construction contracts, invoicing, POs and bills
• 04-procedures — Fieldwire guides (PSEC & SAIYU), Buildertrend workflows, Google service guides
• 07-knowledge-base — Development flow, Class 1 fire CC process

The policy document Revision Management (docs/01-policies/RevisionManagement) has been updated to reflect the new format definition and updated examples.

Going Forward​

From today, all new documents and revision log entries should use the new format:

Rev.YYMM.Alpha       ← for document revisions
YYMMDD               ← for Fieldwire version date stamps

If you find any remaining instances of the old format, please update them and notify the SAIYU PM.

SAIYU — Internal Policy Update, 14 March 2026

Feedback & Bug Reports​

As with any major software release, there may be residual bugs or edge cases that slipped through our rigorous testing.

If you notice anything unexpected—broken links, display issues, or workflow blockers—please please report.

GZ.

This wiki is a set of rules, tools, and guidelines created to support daily operations. Its purpose is to build a common foundation that reduces the learning curve when picking up new projects and ensures consistency across our work.

However, I believe strongly that all rules are made to be challenged. Treat the contents here not as rigid codes, but as tools—a flexible Swiss Army knife for efficiency and clarity. The efficiency we aim for is measured in the long run, through smoother collaboration and fewer preventable errors.

Think of it like carpentry:

• When rounding a corner, you need a specific rounding machine and bit.
• That tool exists for one purpose only, but it does the job with precision.

In the same way, each rule in this wiki is a specialised tool designed to improve a specific task. Use them as they fit the job, and allow for common-sense relaxation when needed to keep work flowing.

You are encouraged to:

• Question and challenge the rules.
• Adapt them when context demands.
• Suggest new tools when you see gaps.

This wiki is not a closed system—it’s a living toolkit, always open to refinement. Read it first, understand the tools, then apply them with judgment.

Enjoy, and use it well.
