I have two of Pages books; the conceptual cost estimating manual and the
estimators manhour manual (HVAC and plumbing) which has a bit more detail on
piping and the like. I find neither particularly accurate, but they are
better than nothing. For example 82 hours to make and fit a 200hp V-belt
motor guard is just plain ridiculous, even with a 70% efficiency factor
built in.
If you have the full set, and nothing better to do could you compare the
piping manhour manual and the HVAC& plumbing manual, and let me know if the
piping man-hour manual has anything useful to add. I vaguely remember
looking at the piping manual years ago and deciding it had nothing
particularly useful to add.
Cheers
Steve

JiJoy,
We happen to have the Gulf Publishing Company series of books in our
library mentioned by Steve. The one he mentions covers estimating on a
very high level where one uses graphs to predict costs from very basic
information. There is another in the series called "Estimator's Piping
Man-hour Manual" which is just that. It gives man hour estimates for
absolutely everything to do with piping. With this book and material
prices from your suppliers you should be able to come up with the usual
detailed estimate using a spreadsheet.
Details of the book are:
ISBN 0-87201-708-7
GULF PUBLISHING COMPANY
Author: John S. Page
My experience with estimating packages is that they are programs written by companies to develop their own business and they seldom make them available if they are any good. If they do, you get it WITHOUT the database of man-hours and prices, which is the heart of the program. Lets face it, if they give you the whole program you have all the tools you need to put them out of business. Would you do that?.
I think I have seen shareware and freeware packages and even free spreadsheets on freeware and shareware sites in the past. You could conceivably use them as a template and populate it with man-hours from the book above and material prices from your suppliers. I would also get the book Steve mentioned because it would be a good way to check the magnitude of your final estimate. His Book has the ISBN 0-87201-134-8. I have not looked for shareware or freeware lately but the relevant sites are easily found by surfing for same on Google.com
Hope that helps
