Planix EngineeringConstruction intelligence
Pick the type of work, enter the quantity and the crew, and get the duration in working and calendar days and the total manhours. Rates are typical GCC benchmarks for a 10 hour day, and you can replace them with your own.
| Manhours | Hours | Per unit |

| Skilled | 0 | 0 |
| Helpers | 0 | 0 |
| Total | 0 | 0 |

The calculator divides the quantity by the crew's daily output, then converts the days back into manhours for every worker on the activity.
The benchmark rates are typical figures for GCC building sites under normal conditions. Real output depends on access, labour skill, heat, supervision and equipment. Use the results for early planning and tender checks, and confirm them against your own project records before you commit to a programme.
How the numbers are worked out and what to watch for.
No. Output is driven by the skilled workers only. Helpers add manhours for the same number of days, which is how most gang rates are built.
Ten hours is a common working day on GCC sites, so the benchmark rates are per 10 hour day. If your day is shorter or longer, change Hours per working day and the daily output scales in proportion.
Working days are the days the crew is on the activity. Calendar days add the rest days, using your working days per week. Public holidays and reduced summer or Ramadan hours are not included, so allow for them separately.
The precast benchmark is an output per erection crew, not per worker. Enter the number of crews and the workers in each crew so the manhours are counted correctly.
The estimate stays in this browser until you clear it. To keep a copy, print it or save it as PDF, or download the CSV and open it in Excel.
