Hi HEF - Merry Christmas, Happy New Year, (pick your favorite holiday, if you are lucky enough to get one!)
Background - farm kid-turned-engineer, worked in a number of fields for 25+ years, now working in scheduling construction.
I typically work for mine owners, planning $100M projects. I support the project team (including design engineers) in answering in some detail "how long will it take". But we typically to that work well in advance of ANY discussion with contractors. We rely on experience (myself, engineering, and higher level construction management) to come up with time estimates. One offshoot that I see is that there is little "out of the box" thinking. In the schedule, it makes a lot of difference if we make a shallow pit for drilling fluid with a dozer versus digging something deeper with an excavator. And it makes a lot of difference if we can have the earthworks contractor do that pit during site prep in summer versus having the driller do it when they mobilize in winter.
I see that there are a number of excavation handbooks that would have some good info about what machine would be suitable for a specific type of earthwork, what size would be optimal, and probably some information about productivities, etc.
Can anyone recommend a book that they use or are familiar with? I can buy something for $10 on ABEBooks, but if it dates to when a TD-20 was state-of-the-art, or the solution to every problem is a Terex TS14, that will be interesting to me, but probably not as useful as something more current.
Thanks in advance
