Most building disputes I see start with a missed or unclear message. A variation agreed on site that never made it into writing. A homeowner who hasn't heard from anyone in three weeks and assumes the worst. A certifier who wasn't told the frame was ready.
A communication plan fixes that by agreeing up front who tells whom, what, and when. On big commercial jobs it's a formal document. On a house it can be one page. Either way, it's worth having before you sign.
What a communication plan is
A communication plan is a short document that sets out:
- Who needs information (the stakeholders).
- What they need to know.
- When and how often they'll get it.
- How it's delivered (email, meeting, app, phone).
- Who is responsible for sending it.
- How problems, changes and complaints are raised.
It doesn't replace the everyday chat on site. It just makes sure the important things don't depend on someone remembering.
What it looks like on your build
Before you sign a building contract, ask your builder how they'll communicate with you. A good builder will have clear answers to these:
- Single point of contact. Who do I call? Usually the site supervisor or a client liaison. You want one name, not a switchboard.
- Regular updates. How often will I hear from you? A weekly email with progress photos is a good standard.
- Response times. How quickly will you reply to a question? Within two business days is reasonable.
- Variations. How are changes priced and approved? Always in writing, signed by both parties, before the work is done.
- Defects and concerns. How do I raise a problem? In writing, with photos, so there's a record.
- Site visits. When can I visit, and do I need to book? Building sites are workplaces with safety rules.
- Stage inspections. Will you tell me before key inspections so I can arrange my own independent inspector?
- Progress claims. When will claims arrive, and what evidence of the completed stage comes with them?
Our C4 Asking the Right Questions checklist covers these and more.
The people involved
On a typical new home build, the stakeholders are:
- You, the homeowner.
- The builder (director or contracts administrator).
- The site supervisor, who runs the job day to day.
- The building certifier, who inspects and approves stages.
- Your lender, who releases progress payments.
- Trades and suppliers, who need accurate plans, selections and dates.
- Your independent inspector, if you've engaged one.
- Neighbours, who appreciate a heads-up before a concrete pour or crane day.
An example plan for a house
Here's a simple version you could ask your builder to agree to.
- Homeowner: progress update with photos and next steps, weekly, by email or project app, from the site supervisor.
- Homeowner: notice of upcoming stage inspections, two days before, by email or phone, from the site supervisor.
- Homeowner: variation quote and approval form, before the work starts, by email and signed, from the contracts administrator.
- Homeowner: progress claim with evidence of the completed stage, at each stage, by email, from accounts.
- Certifier: inspection booking, as each stage is ready, by phone or portal, from the site supervisor.
- Lender: progress claim and certificates, at each stage, by email, from the homeowner and builder.
- Trades: plans, selections and schedule, before they start, by app or email, from the site supervisor.
- Neighbours: notice of disruptive work, two days before, by letterbox note, from the site supervisor.
Keep it this simple. If it's more complicated than a single page, nobody will follow it.
Choosing the right channels
On a build, five channels do almost all the work:
- Site meetings. Best for walking through the job and resolving questions face to face. Follow up with an email summarising what was agreed.
- Email. Your written record. Anything to do with money, time or quality should end up in an email.
- Project app or portal. Many builders use one for photos, documents and selections. Handy, but make sure you can download your records.
- Phone. Fine for quick questions. If anything important is agreed, confirm it in writing.
- Written variation notices. The only acceptable way to change the scope, price or time.
The rule I live by: if it isn't written down, it didn't happen.
Key messages that should always be covered
Every update from your builder should answer:
- Progress. What's been done since the last update and what's next.
- Timing. Are we on schedule? If not, why, and what's the new date?
- Issues. Anything affecting the job, like weather, materials or approvals, and what's being done about it.
- Decisions needed. Any selections or approvals needed from you, and by when.
- Money. Upcoming progress claims and any variations.
Checking it's working
A communication plan isn't set and forget. Partway through the build, ask yourself:
- Am I getting updates when I was told I would?
- Do I know what's happening next week?
- Are my questions answered within the agreed time?
- Is every variation in writing before the work is done?
- Have there been surprises?
If the answer to any of these is no, raise it early, in writing. Most problems are much easier to fix in week four than week forty.
For builders: making it part of your system
If you're a builder, a standard communication plan is one of the cheapest quality tools you can adopt. Set up a template once, use it on every job, and review it at handover. Ask clients what worked and what didn't. Fewer phone calls, fewer disputes and better reviews all come from the same habit: telling people what they need to know before they have to ask.
Quick answers
Do I need a formal plan for a single house?
Not a formal document, but you need the agreements. One page covering contact person, update frequency, response times and how variations and defects are handled is enough.
Can I ask my builder for this before signing?
Yes, and you should. How a builder answers tells you a lot about how the job will run.
What if my builder won't commit to regular updates?
Treat it as a warning sign. Poor communication before signing rarely improves after.
