WHY GRADING CONTRACTORS ABSORB COSTS THEY SHOULD BE RECOVERING.

QUICK ANSWER

Cut and fill variance on grading work happens when actual soil quantities, rock presence, moisture content, or bearing conditions differ materially from what was represented in the bid documents. Most commercial grading contracts include a differing site conditions clause that entitles the contractor to additional compensation when those conditions are encountered — but only if the contractor provides written notice within the contract's specified window, typically 7 to 14 days from discovery. Without that notice, the right to recovery expires regardless of how legitimate the claim is.

CFOS builds a daily production tracking process into every grading engagement that flags changed conditions the day they are encountered, triggers written notice within 48 hours, and opens a change order before the next billing period closes.

7–14 Days
Contract Notice Window
The typical window in commercial contracts to provide written notice of differing site conditions. This deadline is absolute — missing it waives the right to compensation in most contracts.
48 Hours
CFOS Notice Trigger
When production drops below 65% of plan for two consecutive days, CFOS triggers a changed conditions review and written notice within 48 hours of confirmation.

THE NOTICE WINDOW PROBLEM
Missing the Deadline Waives a Legitimate Claim

A grading contractor encounters rock at 4 feet where the geotechnical report showed only gravel to 8 feet. The crew switches to jack hammer and rock saw. Production drops by 60%. The PM calls the GC superintendent, who says 'we know, just keep going, we'll work it out.' The PM keeps going for three weeks while the cost accumulates. When the PM finally submits a change order at the 30-day mark, the GC's legal team denies it on the grounds that the contract required written notice within 10 days of discovery and none was provided.

The changed condition was real. The cost was real. The GC knew about it. The change order is still denied — because the contractual notice requirement was not met. This is not an unusual outcome. It is the predictable outcome of not having a documented changed conditions process.

THE VERBAL DIRECTION PROBLEM
Superintendent Approvals That Never Become Change Orders

On grading work, verbal field direction is constant. 'Take that berm down another two feet.' 'Move the spoils pile to the east side.' 'Regrade that swale because the drainage engineer revised the plan.' Each of these directives adds cost that was not in the original contract. Each one feels too small to make an issue of in the moment. Accumulated over a 16-week grading job, they represent $60,000 to $120,000 in unrecovered work on a $2M contract.

CFOS trains the foreman to log every verbal direction that changes scope — what was directed, who directed it, when, and what the estimated cost impact is. That log becomes the basis for change order submissions in the same billing period the work occurred.

THE QUANTITY SURVEY PROBLEM
Estimating Quantities vs Actual Quantities Diverge on Every Job

Grading estimates are built on plan quantities — cut and fill volumes calculated from design documents. Actual quantities diverge from plan quantities on every job due to survey measurement differences, design changes, and field conditions. When actual cut volumes exceed plan quantities, that additional work is compensable if it results from conditions that differ from the contract documents.

CFOS tracks actual cut and fill quantities weekly against plan quantities. When actual yardage exceeds plan by more than 5% on any phase, the variance is investigated and documented before the next billing period. If the variance is from plan error or design change, a change order is submitted. If it is from estimation difference, it is documented as a lesson learned for the next bid.

01
DAILY FOREMAN LOG WITH CHANGED CONDITIONS NOTATION
Every day, the foreman records actual production — cubic yards cut, filled, compacted — against the plan. Any day where conditions differ from the geotechnical report gets a specific notation: what was encountered, at what depth, what the impact on production was, and who was notified. This creates the contemporaneous record that makes a change order defensible.
02
WRITTEN NOTICE WITHIN 48 HOURS OF CONFIRMATION
When a changed condition is confirmed — rock at unexpected depth, unstable soils, groundwater — written notice goes to the GC within 48 hours. CFOS provides a standard notice template that references the contract clause, describes the condition, states the date of discovery, and reserves the right to additional compensation.
03
CHANGE ORDER SUBMITTED BEFORE BILLING CUT-OFF
Every identified changed condition becomes a change order before the GC's billing cut-off. CFOS tracks every open change order against the cut-off calendar and triggers escalation if a change order is not approved or formally disputed within 21 days.
04
WEEKLY CUT/FILL QUANTITY RECONCILIATION
Actual cut and fill quantities are reconciled against plan quantities every week. Variances above 5% are investigated and documented. This prevents quantity disputes at closeout and creates a paper trail that supports recovery if quantities are disputed by the GC or owner.

COMMON QUESTIONS

FREQUENTLY ASKED.

A differing site condition is a subsurface or latent physical condition that materially differs from what was indicated or reasonably inferred from the contract documents — typically the geotechnical report, borings, and site survey. Common examples on grading work include rock at shallower depth than borings showed, unstable soils not indicated, groundwater above anticipated levels, and buried obstructions not shown on the site plan. Most commercial contracts include a differing site conditions clause that entitles the contractor to additional compensation when these conditions are encountered.
Most commercial contracts require written notice within 7 to 14 days of discovery of the changed condition. Some contracts are as short as 3 days. Missing this window typically waives the right to recover additional compensation even if the changed condition is real and well-documented. CFOS triggers a changed conditions review whenever production drops significantly and sends written notice within 48 hours of confirmation.
