Back-charges and damage disputes

Who Damaged It, and When?

Most back-charge disputes come down to that question. SpatialSense keeps a dated 360° walk of the site every time you capture it, so you can open the same spot before and after the damage and show both sides the same record.

The same spot on two walks, three days apart

The short answer

A back-charge passes a cost to the party that caused it: damage to finished work, clean-up, rework. Many are disputed for the same reason. The only proof is a photo taken after the damage, and nobody can show what the spot looked like before, or when it changed. Regular 360° walks fix that. Every area has a dated record, so you open the spot on the last walk before the damage and the first walk after it, side by side.

What a fair record gives both sides

  • Before and afterThe same spot on two dates, from one locked viewpoint.
  • A window, not a guessThe damage happened between two dated walks, which narrows down who was working in the area.
  • The issue in one placePinned on the spot, with photos, comments, attachments, an owner and a due date.
  • A marked-up snapshotCapture the view, draw on it and export it to attach to the charge.
  • The same link for everyoneShare a link that opens without a login, so the trade sees exactly what you see.

A record both sides can trust

It starts long before the dispute, with a walk you were doing anyway.

  1. A 360° walk of a steel frame site with the floor plan open beside it, captured on a routine visit

    Walk on a routine

    Weekly walks, or one before and one after each trade, give every area a dated record.

  2. An issue on a phone in Konnect, raised from a camera photo and assigned to a finishing crew with a due date

    Pin the damage, assign the trade

    Pin it on the spot with photos and a note, and assign it to the trade’s team with a due date.

  3. A reply from the site crew on the issue thread in Konnect, with a voice note

    Hear their side, in writing

    The trade sees the issue in the Konnect app and replies on the same thread, so both sides are on one record.

Why do back-charges end in arguments?

Forum threads and contract guides tell the same story from both sides of the contract.

No before photo

A photo of the damage shows that it exists. It does not show that it is new, or who was in the area when it happened.

Notice that arrives late

The trade hears about the charge weeks later, after the area is closed up and they can no longer look.

Two records that disagree

Each side has its own photos and its own diary, and neither can see the other’s.

A shared, dated record is fair to everyone. It protects the main contractor from absorbing costs it did not cause, and it protects the trade from paying for damage that was already there.

Settling a back-charge two ways

The same damaged wall, argued two ways.

Start the record this week

The record has to exist before the damage does.

  1. Start a free trial30 days of the full platform, no card details.
  2. Set a walking routineWeekly, or before and after each trade works in an area.
  3. Walk the same routeRepeat the route each time, so viewpoints line up between dates.
  4. Raise it on the spotWhen damage appears, pin it on the walk and assign the trade’s team.
  5. Compare and shareOpen the before and after side by side, and share the link.

Frequently asked questions

What is a back charge in construction?

A cost one party on a project passes to another for work or damage it caused, such as repairing damaged finishes, cleaning up or redoing work. It is usually raised by the main contractor against a subcontractor, under the terms of their contract.

What evidence supports a back charge?

A record of the area before and after the damage, dated, with a clear location; notice to the party involved soon after it was found; and a record of their reply. Your contract sets the notice rules, so check it.

How do dated 360° walks help?

If an area is walked regularly, the damage happened between two dated walks. You can open the same spot on both dates side by side, which narrows down when it happened and who was working there.

Is this fair to subcontractors?

Yes. The same record shows damage that was already there before the trade arrived, and the trade can reply on the issue with its own photos.

Does SpatialSense decide who pays?

No. SpatialSense keeps the record: the walks, the issue and the replies. Who pays is for your contract and the people who run it.
