Construction and trades businesses in Melbourne work in a way that doesn’t fit the standard office-IT mould. Field crews on multiple sites, equipment that costs more than the work van, project deadlines tied to weather and inspections, and clients (especially Tier 1 head contractors) increasingly asking the IT-and-cyber question on every tender. The IT setup that works for a 10-person accounting firm doesn’t work for a 25-person commercial fit-out company.
This post is for the operations manager or owner of a Melbourne construction, trade, or industrial-services business — somewhere between five and a hundred staff — working out how to set up IT that survives the way the business actually operates.
What’s specifically different about construction-and-trades IT
Three constraints define the IT brief:
1. Field-mobile-first workforce. Most staff aren’t at desks. They’re on building sites, in warehouses, in vans, at customer premises. Laptops live in dusty work bags. Phones get dropped. The IT setup needs to assume hardware loss is normal, not exceptional.
2. Job and project workflows that span weeks or months. A commercial fit-out runs eight weeks across three trades, four subcontractor relationships, and twenty material deliveries. The job management software (simPRO, Aroflo, ServiceM8, Tradify, Buildxact, Procore) is the centre of gravity. Outage of that system stops all forward progress on every active job.
3. Tight margins, long-tail equipment, capex sensitivity. Most trades businesses don’t have the spare cash to “just upgrade everything”. Hardware refresh cycles are stretched. Software is often on the lowest-cost tier. Cyber security is sometimes treated as a luxury — until a Tier 1 contractor asks for evidence of MFA before awarding a $400k subcontract.
The IT problems we see at Melbourne trades businesses
From the construction and trades work we’ve done:
- Job management on outdated infrastructure. simPRO or Aroflo running on a server in the back office, last patched two years ago, accessed by field staff over an unsecured remote desktop connection.
- BYOD reality without BYOD policy. Foremen using personal phones for business email, customer photos, and signed-off variation orders. Personal phones get sold or replaced with no offboarding. Customer data goes with them.
- WiFi and connectivity in temporary site offices. A construction site office gets a 4G dongle for three months. The dongle gets plugged into a switch. The switch goes back to head office afterwards with whatever malware visited it.
- Backup that assumes the cloud-hosted vendor handles everything. simPRO has good native backup. The PDFs of signed delivery dockets sitting in OneDrive don’t.
- Email-based fraud against subcontractor invoices. The same “change of bank account” attack we see on professional services firms, but the dollar amounts are bigger and the recovery is harder because subbie payments often happen on tight cycles.
What good Melbourne trades-business IT looks like in 2026
The minimum baseline for a 10-50 staff Melbourne contractor:
- Job management software hosted by the vendor, on the modern cloud version, with all field staff using their own login (not shared)
- Microsoft 365 with Business Premium licensing for office staff and at minimum Apps for Business plus Exchange Online for field staff who only need email
- MFA on every account, no exceptions for “convenience”. Even the apprentice using a hand-me-down iPhone
- Mobile device management (Intune, or vendor-equivalent) for company-issued phones; for personal phones used for work, an MDM-lite policy that lets IT remote-wipe the work apps without touching personal data
- Endpoint detection and response on every laptop, plus disk encryption (BitLocker or FileVault). Job site theft happens.
- Backup of M365 data (OneDrive, SharePoint, Exchange) plus job management vendor exports. Don’t rely on the vendor backup alone — when you need to restore one project’s data without overwriting current data, that’s a vendor support ticket, not a quick recovery.
- A simple incident response plan — one page — that names a decision-maker for “we think we got phished” and a backup if they’re on holidays
- Banking-keyword email alerts and external-sender warnings on inbound mail to prevent the supplier-fraud pattern
The cyber question on tenders
If you bid for work with Tier 1 head contractors, government clients, or large commercial property owners, the cyber-security questionnaire is now standard. The questions are usually a subset of the Essential Eight: MFA, application control, patching cadence, EDR, backup, IR plan, training. A trades business that can answer “yes” with one-line evidence on each gets through quickly. One that can’t gets pushed down the shortlist.
Our managed security service includes an annual evidence pack you can attach to tender responses. Saves a fortnight of last-minute scrambling per bid.
Job-site connectivity considerations
A Melbourne construction site is a temporary office. The connectivity options are usually 4G/5G mobile data, sometimes a fibre-to-the-site if the site is large enough, occasionally a Starlink or similar. The trick is making the connection secure without the site office staff having to fiddle.
The simple answer in 2026: a vendor-managed mobile router (Cradlepoint, Peplink, similar) with a pre-configured VPN back to head office, dedicated to the site for its lifetime. The router travels site-to-site. The configuration doesn’t change. Office staff use the same WiFi name and password they would at any TechAssist client’s premises.
Backup specifically for trades businesses
Job photos, signed delivery dockets, signed variation orders, sub-contractor agreements, retentions ledgers, warranty documents. Most of these live in OneDrive, SharePoint, or the job management vendor’s document store. Native vendor backups are usually production-only — not granular point-in-time restore. Add a third-party backup that gives you 90 days of point-in-time recovery for M365 and at least 30 days for the vendor system. Backup and disaster recovery in our service includes both.
Should you have internal IT or use an MSP?
Most Melbourne trades businesses under 50 staff don’t have internal IT, and shouldn’t. An MSP that understands site-mobile workflows and tender requirements is a better fit. The MSP handles laptop and phone setup before the field staff start, manages the licensing as headcount changes, and answers the tender cyber questions.
Our IT support for construction and trades service is shaped by the work we’ve done with Melbourne contractors. The managed IT services Melbourne page covers the broader business-side detail.
What to do next
If your job management software is hosted on a server in your office and you can’t immediately confirm when it was last patched, when the last backup test ran, and who has admin access — those three questions are the priority. Get an answer in writing this fortnight.
