How HBC stopped paying for work that wasn't done

Their quantity surveyor checked subcontractor claims against 360° photos of the site. Room by room, on every visit. Here's what the photos showed.

What we did for HBC

Delivering measurable savings through complete visual records of construction

The brief

Construction projects often require teams to answer questions long after work has been completed. Traditionally, this relied on site diaries and individual photographs.

What we deployed

HBC implemented Oculo across multiple projects, capturing regular 360° walkthroughs throughout construction.

✓Ramsden Building for the University of Huddersfield
✓Rotherham Markets
✓Rye Park in Newcastle-under-Lyme
The outcome
✓£100,000 - £150,000 identified in overclaimed works
✓Tens of thousands of pounds protected through subcontractor claim evidence
✓Pre-existing defects proven instantly using historical scans

Creating a Complete Visual Record

HBC implemented Oculo across multiple projects, capturing regular 360° walkthroughs throughout construction.

The scans created a permanent visual timeline, giving both commercial and site teams the ability to return to any location at any point in time. Whether reviewing completed works, investigating issues or validating commercial claims, teams can instantly access a visual record of exactly what happened on site.

Commercial Impact: £100,000 - £150,000 Identified in Overclaimed Works

One of Oculo's biggest commercial impacts came during the refurbishment of the Ramsden Building at the University of Huddersfield.

Senior Quantity Surveyor Ashley Etherington used Oculo during monthly valuations to verify subcontractor claims. Rather than relying solely on submitted quantities, Ashley reviewed completed works using Oculo's historical timeline.

In several cases, subcontractors had overclaimed on their works, while Oculo showed what had actually been completed. With traditional finishes in historic buildings coming at a premium, these discrepancies quickly became significant.

By validating completed works against Oculo's visual record, HBC estimates it identified approximately £100,000 - £150,000 in overclaimed works.

Resolving Contractor Disputes: Tens of Thousands of Pounds Protected

Oculo also became a key evidencing tool during conversations with subcontractors.

During a conversation, another subcontractor argued that delayed access had prevented works from starting on time. Using Oculo's timestamped imagery, HBC was able to demonstrate exactly when operatives were present on each floor.

“Our site management used Oculo to basically say, 'Here's a picture of some of your team on Floor 1 or Floor 2 at this date.'”

Ashley estimates this evidence helped avoid tens of thousands of pounds in potential disruption claims.

Protecting Against Existing Defects

For Site Manager Carl Gelder, one of Oculo's biggest benefits came during an investigation into hairline cracking on an existing building. Questions arose about whether the works had caused the damage.

Instead of searching through hundreds of photographs, Carl simply returned to the project's first Oculo scan. The scan clearly showed the cracking already existed before construction began.

“I could go straight back to our first scan and showed it was existing... without the system I would have been a bit stuck.”

The ability to prove pre-existing conditions protected the project from unnecessary remediation costs and lengthy investigations.

A Tool for the Entire Project Team

One of the biggest advantages highlighted by HBC was that Oculo delivers value across multiple roles throughout the project lifecycle.

Commercial Teams
✓Validate subcontractor payment applications
✓Challenge overclaimed works
✓Resolve commercial disputes
✓Support monthly valuations
Site Teams
✓Investigate existing conditions
✓Verify progress
✓Review historic site conditions
✓Support client discussions
✓Reduce investigation time

As Carl summarised: “It's a very rounded system.”
