(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.
Does anyone have any good book recommendations which ciontain outputs.
Ideally some sort of catelogue book with a whole range of outputs.
I know outputs are specifici to location but it would be a nice starting point to refer to?

At times I use RS Means as a reference to plug in numbers for which we do not have historical records.
I look at the production per day per crew and apply a factor to account for a reduced productivity due to local ways of doing things, due to local hot weather and at the end look for the crew composition, the unit prices never look at them.
Because we use it only for a small percentage of our total estimate we play it safe and reduce productivity to 70% that shown in RE Means. This will accommodate for some idle time or missing resources due to vacation or sick leave. You plan to do certain work with 10 men during 10 days but some will be absent during this time. I believe this fact is one of the reasons estimates tend to be too optimistic.
Used in this way you account for difference in pay rate, local cost of materials, because I look for productivity a few years old book is still good enough.

Hi Tony,
There are a lot of factors affecting production rates and outputs that nobody has dared to venture in this area, you can find some reference in the internet, and as you said it maybe a good start.
Best regards,
Daniel
