Purpose and outcome

This record is your simple proof that you:

Briefed the job (what’s happening today and what’s changed).
Coordinated the work (sequence, access, plant routes, other trades, neighbours/public).
Consulted workers (questions, concerns, suggestions were invited and captured).
Agreed actions (clear owner + due date, and closed out when done).

Good completion looks like: names and signatures are complete, the key hazards/controls are clear in plain site language, worker comments are written down (not “none”), and any actions have an owner and date.

Who uses it (roles and responsibilities)

Role	What they do
Site supervisor / working foreman	Leads the briefing, checks understanding, records what was covered and what workers raised, assigns actions, signs the confirmation.
Operatives and subcontractors	Attend before starting, sign in, raise issues/ideas, follow the agreed controls, sign to confirm understanding.
Principal Contractor (if on a PC site)	May require this record, may review it during site checks, and may need to be informed of changes/hold points.
Company owner / contracts manager (small firms)	Spot-checks quality, follows up overdue actions, keeps records organised for audits/clients.

When to use it (triggers and frequency)

Start of shift where there are changing conditions, multiple trades, or higher-risk work.
Weekly coordination talk (especially on longer jobs or busy sites).
When the method/plan changes: new sequence, new area, new plant, new people, new access, design change, weather change, services found, etc.
After an incident or near miss to capture learning and the change in approach.
Before high-risk activities starting for the first time on that job/phase (e.g., work at height, lifting, excavation, hot works).

Rule of thumb: if you would say “let’s just run through this quickly”, use the record.

Before you start (what you need in your hands)

Today’s plan: what’s being done, in what order, by who.
RAMS / method statement (and any updates) and the key controls you expect people to follow.
Site rules and emergency info: muster point, first aider, fire points, access routes.
Permits/authorisations if used (hot works, excavation, electrical isolations, confined spaces, lifting plans).
Interface information: other trades working nearby, deliveries, neighbours/public routes, shared access, working above/below.
Checks relevant to the day: plant pre-use checks, scaffold/MEWP checks, service scans, lifting gear certs (as applicable).

Tip: take 2 minutes before the talk to walk the area and spot changes (weather, access blocked, new openings, deliveries due, new hazards).

How to complete it (step-by-step)

Step 1 — Fill in the briefing details (top section)

Write the site, date, time and briefing type (start of shift / weekly / method change / learning).
Record who briefed and the supervisor/site lead.
Note the main work today in simple terms (e.g., “install steels to rear extension”, “dig trial holes to locate services”).
Use “What changed?” properly: new area, new sequence, new plant, new crew, weather, access changes, other trades, design change.

Step 2 — Sign-in (attendance)

Everyone doing the work should print name + sign before starting.
Add company/trade and task today (helps show coordination).
If someone turns up late, brief them separately and add them before they start.

Good practice: don’t sign for people. If someone can’t sign, write the reason and have the supervisor initial it.

Step 3 — “What was briefed” (ticks + short notes)

Tick only what you actually covered. A few meaningful notes beats ticking everything.
In the notes, capture the site-specific point for today (not generic lines).
Focus on what will stop someone getting hurt today: access, edges/openings, overhead work, plant routes, lifting, excavations, hot works, dust/silica controls, isolations.

Example of useful notes: “Telehandler route along east side only; banksman required at gate. No reversing near welfare.”

Step 4 — Worker consultation (what workers raised)

Ask the questions and write down what people say (who/what/where).
Record the immediate response (even if it’s “checked and OK” or “agreed to change sequence”).
If someone flags something unsafe/unclear, treat it as real: stop and sort it rather than “we’ll see how it goes”.

If the group is quiet: use prompts like “Any clashes today?” “Anything missing?” “What’s the one thing that could bite us today?”

Step 5 — Agreed actions (owner + date)

Only record actions you can actually follow up.
Each action must have:
- What (clear and specific)
- Owner (named person, not “team”)
- Due date (realistic and soon)
- Done date when completed
If an action is critical to safety, treat it as a hold point (don’t start until it’s done).

Step 6 — Stop/hold point (if needed)

Use this when you have to pause work because it’s unsafe or the method isn’t clear.
Write what was stopped, why, what changed, and who authorised restart.
When you restart, do a quick re-brief so everyone hears the change.

Step 7 — Confirmation (signatures)

The person who delivered the briefing signs.
The supervisor/site lead signs (often the same person on small jobs, but sign both lines if applicable).
Set the next review / next talk (date/time). This helps show ongoing coordination.

Review and sign-off (what “good” looks like)

Supervisor check on the day: attendance complete, key controls match the actual work, actions assigned and realistic.
If you’re on a Principal Contractor site: share or make available if requested, especially where actions affect other trades or site rules.
Management spot-check (weekly/fortnightly): look for quality of notes, evidence of consultation, and close-out of actions.

Escalate when: the issue affects other trades, needs extra kit/money/time, involves a design change, requires a permit/competent person, or you cannot make it safe with the resources on site.

Recordkeeping (storage, version control, retention)

Keep it with the job paperwork: site file, project folder, or PC document system (if you’re working under one).
Scan/photograph completed sheets regularly so they don’t get lost or damaged.
Name files clearly so you can find them fast (example): SiteName_ConsultationBriefing_YYYY-MM-DD.
Keep actions trackable: if actions run across days, copy open actions into the next briefing or track them in your action log, then mark “done” when closed.

Retention: keep for the life of the project and long enough to answer client/PC/HSE questions later. If your company has a set retention period, follow that.

How often it should be reviewed or updated

Daily if conditions change often, multiple trades are present, or risk is higher.
Weekly minimum for longer jobs as a coordination touchpoint.
Immediately after any significant change: services found, access changes, new plant, weather shift, incident/near miss, new subcontractor, design change.

Don’t overcomplicate it: a short “method change” briefing that’s well recorded is better than rewriting paperwork later.

Common mistakes (and how to avoid them)

Ticking everything with no notes → Tick only what you covered and add one line that makes it site-specific.
“Nothing raised” every time → Ask a couple of prompt questions and write at least one real point (even if it’s “checked access route; agreed keep gate shut”).
Actions with no owner or date → No owner/date = no action. Name someone and set a due date.
Late joiners not briefed → Add them before they start. Do a quick catch-up briefing and record it.
Briefing doesn’t match the real work → If the job changes, do a quick re-brief and complete a new record (or clearly note the change and controls).
Not using the hold/stop section → If it’s unsafe or unclear, stop. Writing it down protects the team and shows good control.
Illegible names/signatures → Ask for printed names as well as signatures.
Paper lost or damaged → Take a photo/scan the same day and store it in the job folder.

Worked example (realistic site scenario)

Scenario: Small extension job. Today you’re installing lintels and cutting out a new opening. A delivery is due mid-morning and a roofer is working above later.

Briefing details: Start of shift. “What changed?” = “Delivery time moved earlier; new opening created; rain forecast affects access.”
What was briefed (notes examples):
- Plan for the day: “Prop opening, fit lintel, rebuild, then tidy for roofer access.”
- Work at height: “No standing on blocks; use podium steps; keep edges protected; rescue plan = ladder available, first aider on site.”
- Dust/silica: “Wet cutting where possible; FFP3 for chasing/cutting; vac on grinders; keep clients out of area.”
- Interfaces: “Roofer overhead after lunch—no work below without agreed exclusion zone.”
Workers raised: “Labourer says walkway is slippery at side gate.” Immediate response: “Salt/grit applied, route changed to front path until it dries.”
Agreed actions:
- “Put barrier/exclusion zone under roof edge before roofer starts” — Owner: Supervisor — Due: Today 12:00.
- “Confirm delivery location and banksman for unload” — Owner: Driver/Foreman — Due: Before delivery arrives.
Hold point (if needed): If props/strongboys not available, record stop and do not start opening until kit is on site.

Quick quality check (60 seconds)

✅ Could someone who wasn’t there understand what the job is and what’s different today?
✅ Are the main hazards and controls written in site language (not generic)?
✅ Did workers get a real chance to speak, and is it recorded?
✅ Do actions have owner + due date, and will you actually chase them?
✅ If something was unsafe/unclear, did you stop and record the change and restart authorisation?
