Construction business
Construction schedule overrun overhead
Separate the additional time-related cash expense of a supplied schedule extension from already-budgeted direct work.
Your inputs
Complete the fields for your selected method. Zero means intentionally zero, not unknown. Currency selection labels amounts; it does not convert exchange rates.
How this calculation works
added time-related cost = extra elapsed days × daily overhead + extra standby person-hours × supplied hourly cost + other added time costs
For residential or commercial company costing. Use supplied job records, measured labor and quoted total expenses. No material takeoff, shopping list, supplier sourcing, code interpretation, engineering design or legal entitlement is provided. Count only incremental expenses caused by the extension; do not automatically allocate every original job cost again. This does not assign delay responsibility, calculate damages, certify schedules or establish contractual reimbursement.
What information do I need?
Use records for the same job, equipment or accounting period. Only the fields for your selected entry method are required. An unknown amount is not zero.
Input definitions and where to find them
- Extra elapsed days in supplied scenario (days): Owner delay scenario and documented incremental site expense. Owner records or explicit assumption; no account connection or maintained rate tables required.
- Additional time-related job overhead per day (selected currency): Owner delay scenario and documented incremental site expense. Owner records or explicit assumption; no account connection or maintained rate tables required.
- Extra paid standby person-hours not in other costs (person-hours): Owner delay scenario and documented incremental site expense. Owner records or explicit assumption; no account connection or maintained rate tables required.
- Supplied all-in standby labor cost per person-hour (selected currency): Owner delay scenario and documented incremental site expense. Owner records or explicit assumption; no account connection or maintained rate tables required.
- Other additional time-related expense (selected currency): Owner delay scenario and documented incremental site expense. Owner records or explicit assumption; no account connection or maintained rate tables required.
Use the Where to find this value controls beside the inputs for available work-it-out helpers. Estimates remain your assumptions; a helper does not verify the source figures.
Worked example
Example amounts use US dollars (USD).
Example answer: Additional schedule-extension cost is $4,200.00 for the illustrative inputs below.
Example inputs
- Extra elapsed days in supplied scenario: 10.00 days
- Additional time-related job overhead per day: $250.00
- Extra paid standby person-hours not in other costs: 40.00 person-hours
- Supplied all-in standby labor cost per person-hour: $30.00
- Other additional time-related expense: $500.00
- Additional schedule-extension cost
- $4,200.00
- Additional daily overhead component
- $2,500.00
These illustrative values are not recommended rates or industry averages. Replace every example input with your own figures.
Use the result well
Price a supplied delay cost exposure.
Keep inputs on the same scope and time basis. Calculations retain precision internally; displayed values generally round to two decimal places, with extra precision for very small values and whole-unit rounding where required. Economic comparisons describe your supplied assumptions and do not guarantee future results.
