Description
Apply a supplied idle-plant credit fraction.
Construction bookkeeping distinguishes installed, accepted, credited and reworked quantities, as well as contractual cost and schedule conventions. A local variance or budget term can expose a gap without verifying work quality, payment entitlement or the project critical path.
Apply a supplied idle-plant credit fraction.
When to use this tool
Use Plant Idle Credit Base when checking a supplied construction quantity, charge, record or schedule convention.
How to use the tool and how it works
- Enter idleHours, hourlyHire, creditFraction, fixedCharge, includeFixed. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read gross, credit, net. Use the output convention below.
Apply a supplied idle-plant credit fraction. Require nonnegative idleHours/hourlyHire/fixedCharge and fraction in [0,1]; gross = hours*hire+fixed, credit applies to variable hire plus fixed only when includeFixed, net = gross-credit.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| idleHours | Idle Hours | Required. Finite number; minimum 0. |
| hourlyHire | Hourly Hire | Required. Finite number; minimum 0. |
| creditFraction | Credit Fraction Unit: 1. | Required. Finite number; minimum 0; maximum 1. |
| fixedCharge | Fixed Charge | Required. Finite number; minimum 0. |
| includeFixed | Include Fixed | Required. Boolean. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| gross | Gross | Required. Finite number. |
| credit | Credit | Required. Finite number. |
| net | Net | Required. Finite number. |

}Limitations and assumptions
- Actual standby eligibility, contractual exclusions and recoverable amounts are not established.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Use verified project records, a complete schedule and governing contracts; involve qualified construction, engineering or legal professionals for practical decisions.
