Case study · Construction

Connecting four sites for a regional builder.

A construction company with offices in Southport, Robina, and two Toowoomba locations had no unified network. Each site ran an ad-hoc setup, and cross-site file sharing happened over email attachments and USB drives. We made the four offices behave like one.

The challenge

Four offices, four islands.

Each site had grown organically. Different ISPs, different firewalls, different Wi-Fi setups, and no shared identity. A project manager working across two offices carried two sets of credentials and moved files manually.

- 01
Inconsistent security posture
One site had a modern firewall, another had a consumer-grade router, and the others were somewhere in between. If an incident happened at the weakest site, there was no barrier between it and the rest.
- 02
File sharing by email and USB
Drawings, estimates, and project documents moved between sites on email attachments or USB drives. Version drift was constant, and nobody had confidence that the file open on their screen was actually the latest.
- 03
No remote access that worked
Project managers spending time in site cabins couldn't reliably reach head-office systems. Estimating software was unreachable from a laptop, and shared drives only existed if you were physically in the office that owned them.
01 · Site-to-site VPNs, standardised firewalls

Four sites, one logical network.

We put matching firewalls into every office, built site-to-site VPNs that tie them together, and consolidated Internet termination so traffic between sites moves over secure tunnels rather than the public Internet.

The four offices now behave as one network with one security perimeter.

02 · Managed Wi-Fi, staff and visitor

Proper wireless at every site, properly segmented.

Managed Wi-Fi went into every location with a separate visitor network, subcontractors, surveyors, anyone walking through, kept well away from staff traffic and shared drives.

Coverage, performance, and security are the same regardless of which site you're in.

03 · Remote access that site cabins can rely on

The office is wherever the laptop is.

Project managers now get secure remote access to shared drives, estimating software, and the PM tools they use daily, whether they're in the Southport office, a Toowoomba site cabin, or somewhere in between.

Identity is unified, so one login gets you everywhere you're supposed to be.

The outcome

One drive, one identity, one network.

Everyone works from the same shared drive regardless of which office they walked through that morning. Version drift on project files is gone, and new offices go through a standard build rather than a new adventure.

- 01
Unified file access
Drawings, estimates, and PM documents live in one shared environment. No more emailing attachments between offices, no more USB drives in transit.
- 02
One security posture
Every office runs the same firewall configuration, the same Wi-Fi segmentation, and the same endpoint protection. The weakest link isn't a whole site anymore.
- 03
A template for the next office
When the business opens another site, there's now a known build: firewall, Wi-Fi, identity, drives, a known quantity rather than another one-off.

Multiple sites, no unified network?

Your offices should behave like one business.
