I've got some books (Spon's Civil engineering, MEP and Architects). I can send you these pricebooks in pdf format if it appropriates for you. I can easily find essential activities and compare these rates with your own calculation.

It's the same thing for piping erection, we use Inch-meter, for exemple a pipe of 6Inch and 3 meters = 18 Inch-meters but for this 18 I.M it's possible to weld a joint of 6 ID but with different thikness. I thing that the best unit is IDC inch dimater corrected is a method to convert each diameter compared to a standard thikness for exemple 6 Inch standard epaisseur is 9.53 mm joint=6IDC but 6 Inch with 14.27mm joint = 6ID * (14.27mm/9.53mm) = 8.98 ID

Bill, for me, the rule of thumb is: There Is No Rule Of Thumb. Why? For Example: In Piping Works you may use "Inch-Dia" for calculating fabrication works for piping spools. While during erection and hydrotests, you may use "Inch-Meter". The unit "Inch-Dia" perse only represents the number of joints and diameter of pipes for a certain spool but cannot reveal the thickness and the type of pipes. In other words, these so-called specific units are just tools for "Guesstimates". Welding works depends on how many passes you need to make and you may need to grind before you can make another pass.
I understand what you are saying. The only way to get truly accurate manhour figures is to be very specific to the site and the task. I have already carried out this task and I have prepared very detailed manhours specific to the job I'm working on but I would like a general 'rule-of-thumb' just to cross-check what I have prepared to make sure I'm in the ballpark with my calculations.
Dimitrios,
Thanks for your suggestion. I have located the book on Amazon. I also tracked down a number of books by John S Page with manhours. The books seem to be a little dated. Do you have any experience with his work and is it relevant?

Too many books and too many options and conditions and maybe different in every specific scenario. Hence, no one can be a master of all disciplines. A bulk excavation is not as simple as it is. First you need to conduct soil analysis, boring tests etc. Which of course have its own production rates as well. After that, you'll need to construct ramps, slope protection, side cave-in protection, and perhaps sheet pilings etc. etc..which of course have their own unique production rates as well. Realistic production rates can only be derived after Engineering and specific method statements have been set or put in place.
