SITEWORK

SITEWORK CONTRACTOR WEATHER DELAY CASH FLOW IMPACT.

QUICK ANSWER

Weather delays on sitework aren't just scheduling problems. They're financial problems. Every rain day costs crew standby, equipment idle time, and erosion control maintenance against no billable production. When those costs aren't documented, not billed where the contract allows it, and not planned for in the cash forecast, they come straight out of net margin on every project that runs through wet season.

Most sitework contractors absorb weather delay costs without question because they assume the risk is theirs. Sometimes it is. But owner-caused delays, delays from other trades clearing areas, and delays caused by conditions materially different from the contract documents all carry potential cost recovery. The contractors who recover those costs are the ones with documentation systems that run automatically, because the claim gets built out of records nobody had to remember to keep. The ones who recover nothing usually knew the cause and never wrote it down.

THE DEFINITION

WHAT IT MEANS.

Weather delay cost on a sitework project is the crew standby, equipment idle time, and erosion control maintenance a contractor carries on days when rain stops billable production.

THE THREE WEATHER DELAY COSTS

WHAT WEATHER COSTS A SITEWORK CONTRACTOR, LINE BY LINE.

01

Crew standby, the largest single line item

A sitework crew on standby costs 60 to 80 percent of their active production rate, because foremen and superintendents are salaried or guaranteed. On a 6-person crew at $38 per hour fully burdened average, a full-day weather standby costs $1,824. Three weather standby days in a month is $5,472 against zero billable production. Across a 5-month wet season, that's a margin line that belongs in the cash forecast rather than being discovered after the fact.

02

Equipment idle time, where depreciation and insurance continue

Equipment on a wet sitework project doesn't stop generating ownership cost. A $180,000 excavator on a 6-year depreciation schedule generates $82 per day in depreciation whether it's running or not. A 10-day weather delay on a project where that excavator is committed generates $820 in idle depreciation cost before maintenance and insurance. When that cost isn't tracked and not in the cash forecast, it becomes a surprise margin erosion at project close.

03

Erosion control maintenance after weather events

Wet weather damages erosion controls. Silt fence fails under heavy rain, inlet protection fills and requires cleaning, and the maintenance and reinstallation is real labor and material cost. Whether it's your obligation or a billable event depends on whether the original scope included maintenance for the rainfall intensity that occurred, and on whether construction activity outside the original plan caused the damage. Most sitework contractors absorb those costs without asking the question. Document the cause before you send the crew.

THE ARITHMETIC

WHAT IT LOOKS LIKE IN DOLLARS.

One month of rain, priced out

A 6-person crew at $38 per hour fully burdened costs $1,824 for a full-day weather standby, so three standby days in a month is $5,472 against zero billable production. Add a committed $180,000 excavator generating $82 per day in idle depreciation, and a 10-day delay adds $820 more before maintenance and insurance. None of that carries a billing line unless somebody wrote down why production stopped.

THE DOCUMENTATION AND BILLING SYSTEM

WHAT TO DO WHEN THE RAIN STARTS, IN THIS ORDER.

Daily weather log

Rainfall amount, temperature, wind, and site conditions get documented every day, timestamped and attached to the project file. That log is the evidence base for every delay claim and change order conversation. It has to exist before the event, which is why it's a daily habit rather than a response.

Crew and equipment standby record

Record the hours and headcount on site each standby day, with confirmation of why production wasn't possible. That record converts to a dollar figure when the delay claim gets built. Without it, the claim is an assertion instead of a calculation.

Written notice to the GC

Send a same-day email when a weather event causes a delay that will affect schedule or cost. A notice like this preserves contractual rights, and it reads as procedure rather than grievance. No notice means no claim.

Change order review after the event

Determine which costs are billable once the event has passed. Damage caused by owner-directed scope changes, and rainfall exceeding the contract threshold, both carry potential recovery. Submit before the next billing cycle rather than at closeout, because a claim submitted at closeout is a claim you're negotiating from weakness.

The cash forecast implication

Weather delay costs are predictable in aggregate. A sitework contractor in a market with 45 wet days per year should have those 45 days modeled in the 13-week cash forecast as reduced production weeks. That way the LOC draw in February is planned in November instead of discovered when payroll is due.

COMMON QUESTIONS

FREQUENTLY ASKED.

Most commercial contracts have excusable delay provisions that extend the schedule without cost. Cost recovery typically requires either an express provision or a changed conditions argument, meaning conditions materially different from what the contract documents represented. Review the specific contract language with your attorney before submitting a weather-related cost claim.
Pull your weather delay history from the last three years: days lost by month, by project type, and by geography. Calculate your average standby cost per weather day. Then include a weather allowance line in every bid that reflects your historical exposure. Most sitework estimators use a generic contingency without ever calculating what weather costs them.
Weather delay cost tracking is built into the monthly cost-to-complete for sitework projects. Standby days are coded separately from productive days, so the cost is visible in the job cost report rather than buried in a labor overrun. The 13-week cash forecast models reduced production weeks during historically wet periods.
