Input latest known or 'guesstimated' quantities and manhours* for each discipline. Review resultant weightings and if considered seriously disproportionate, then amend inputted figures accordingly. Enter measured quantities to date and progress percentages will be calculated, by discipline & overall. *NOTE - For this Calculator to function, estimated quantities and manhours (obtained elsewhere) MUST be inputted for all the disciplines, whether reliable or simply educated guesses. However, simply enter '1' in both columns wherever an activity is not to be included. Updating can come later as more info becomes available and the earlier that construction progress assessments commence, the better. NOTE: Activity discipline headings, activities and measurement units can be changed to suit user's specific WBS.
