can anyone recommend a good book for estimating.
i would like the book to cover plating and welding, i am involved with a large duct erect job.
there seems to be a few available but i you cant see the content on the Internet :-)
i would like a set of norms that will tell me that welding a 6" NB pipe 40 sched will be .....................
cutting 1 meter of 6 mm plate will be .....................
this would help prove my workings when the QS come calling, any one know a good book?
