Manual vs Automated Asset Inspections: Which Is Right for Your Facilities?

Manual inspections send a person to look at each asset and write a report. Automated inspections capture each site with drones or sensors and use software to find and rank defects. Manual inspections suit a few sites or detailed hands-on checks. Automated inspections suit portfolios where you need consistent, frequent data across many sites.

Most facility teams end up using both. Here's how they compare, and how to decide where each one fits.

Manual vs automated inspections side by side

What a manual inspection involves

A qualified inspector visits the site, walks the asset, takes photos and writes up findings. For roofs and facades, that often means ladders, elevated work platforms or rope access. The result is usually a PDF condition report that describes the asset at a single point in time.

Manual inspections are flexible and can catch issues that need a hands-on check. But they're slow to scale, depend on each inspector's judgement, and leave data scattered across reports that are hard to compare year to year.

What an automated inspection involves

With Asseti, a licensed drone operator flies each site and creates a high-resolution 2D and 3D digital replica. AI detects defects, categorises them by component and ranks them by severity. Everything lands in a central asset register and dashboard, and prioritised issues flow into your existing EAM or CMMS.

Because the method is the same every time, each new capture shows what has changed since the last one. Teams can review any site from the office and send people only where the data shows a real problem.

When manual inspection still makes sense

• Interior, hands-on or regulated checks that need a qualified person on site
• One or two sites with simple, easy-to-reach assets

When automated inspection wins

• Many sites spread over a wide area
• Roofs, facades, towers and other assets that are hard or unsafe to reach
• Boards, owners or insurers asking for portfolio-wide condition data

The hybrid approach most teams use

Automate the external, at-height and portfolio-wide captures. Then send inspectors and contractors where the data shows a real problem. That's how one GHD Advisory client reported critical issues 12 times faster at 80% lower cost.

Customers often find more uses once the data is in one place. At Mirvac, facility managers now use Asseti day to day for site maintenance, contractor onboarding and periodic regulatory inspections.

Frequently asked questions

Are drone inspections accurate?

High-resolution 3D models let teams zoom into individual components from the office. Findings can be verified on site where needed.

Do automated inspections replace inspectors?

No. They focus inspectors on the sites and defects that need them, and take people off roofs when a visual check is all that's required.

How often should facilities be inspected?

Many portfolios inspect once a year. Automated captures make it practical to inspect more often, so changes are caught earlier.
