"The Ground Wasn't What We Expected."

The Reality

Footings go in and the ground turns out softer, rockier, or just different from what was assumed at quoting stage. The engineer revises the reinforcing. A retaining wall's design gets adjusted for a compliance reason that has nothing to do with your workmanship. None of that is unusual for the trade — but if it isn't written down when it happens, it's very hard to claim for once the job's finished and everyone's moved on to the next site.

Where Subcontractors Lose Money

• check_circleUnexpected ground conditions at footings (rock, soft fill, unsuitable material) absorbed as part of the original price
• check_circleEngineer-directed reinforcing or foundation changes with no corresponding cost adjustment
• check_circleAdditional concrete or blockwork instructed on site, never formally varied
• check_circleRetaining wall redesigns for compliance reasons, changing scope after work has started
• check_circleWeather-dependent laying and curing delays with no extension of time claimed
• check_circleDelayed inspections or access issues extending time on site at your cost

What The Contract Actually Requires

Many masonry subcontracts require a formal instruction before ground-condition or design changes are priced and carried out, and a documented extension of time claim for weather-dependent delays rather than just absorbing the lost days. What exactly counts as a "differing condition" under your contract is worth checking directly, since this varies. What's consistent: the moment ground conditions turn out different from the drawings is the moment to start documenting, not after the wall's built.

How Subbie HQ Helps

• check_circleLog ground condition and design changes as an Update, with photos, the moment they're found
• check_circleRecord additional concrete, blockwork, and labour via Day Works Sheets
• check_circleTrack weather-affected days against the job as they happen
• check_circleKeep engineer correspondence and revised drawings in one place
• check_circleGet a ground-condition or design change formally approved with a secure link the engineer or PM can act on with no login, before the wall's already built

From Site Event → Evidence

Condition or design change found → logged as an Update with photos → tagged to a Site Instruction or Variation → Day Works and materials recorded → bundled into a Variation Package when it's time to claim.

Why This Matters

Ground conditions and engineering changes are often the single largest source of unclaimed cost on a masonry job — and they're also the easiest to prove, if you document them the day they happen instead of trying to reconstruct them weeks later.
