Tips on using this forum..

(1) Explain your problem, don't simply post "This isn't working". What were you doing when you faced the problem? What have you tried to resolve - did you look for a solution using "Search" ? Has it happened just once or several times?

(2) It's also good to get feedback when a solution is found, return to the original post to explain how it was resolved so that more people can also use the results.

Today I got a new thumb rule from my manager

That is 22% of the project cost is the Budgeted manhour.

Hi Vasanth,

Some times it depends on the High,low and medium Production rates.

That figure may be varying depends on the projects and the country wise..

Some attributes about the project type - building/civil, structures/earthwork, design-build/unitCost, project type, selfPerformed/constructionManaged, union/non-union, other attributes you think of. The general answer without project attributes, from historical data gathered in Western North America: High 40%, Low 20%, average 30%, standard deviation 5%, sample size 100 projects.
