Cost estimate of Geotechnical Projects
Cost estimate of Geotechnical Projects
(OP)
Are you aware of any geotechnical book or source that gives guidance on cost estimate for various projects in geotechnical engineering.. ?
I have finished the preliminary design and caculated the quantities. I just want to survey the operations involved in the project with making sure that I did not miss any operation ( or at least I cover the most of the operations). I know that this is experienced based matter, (I have 10 years of experience) but still any source /book that deals with these matters will help.

Any source pertaining to any or preferably both ( geotechnical investigations, Design , Construction Cost and monitoring) will be great. Again would be great if one finds a source (or sources) covering different types of projects Shallow Found, Deep Found (piles, shaft), Pavemenet, Earth structures (tunnels, dams)... and so on.

if someone does happen to know of a good book, i'd be interested to see what it says...

Costs for geotechnical investigations are suspect and I doubt that you will find anything that makes any sense.
For instance, a seasoned geotechnical engineer will cost more, but his/her recommendations will hold more merrit as opposed to a less senior engineered report that will have less substance that you are looking for, but may be cheaper. Remember engineering is about adding value......yes we need to charge for our services, but the client needs to reap the rewards in the end. The end must justify the means........so if you cost the client 10,000 but can save him/her $1,000,000 in cost over runs and extras, well thats value added.
I would suggest that you maybe talk with clients, other professionals and people who use engineers and see what they suggest for rates in your area. Prices for engineering differ in certain locations and can be significantly different as well drilling costs are variable as well.
Good luck with your quest though.

As for construction costs, including deep foundations, you might consider one of the RS Means estimating guides. There are several so select the one closest to your project needs. They are usually quite conservative, but they are recognized and defensible.
Another estimating guide is Walker's. It is probably in its 40th edition by now. It is less specific than Means, but still offer some relevant info.

I'm off my soapbox now

RE: Cost estimate of Geotechnical Projects
Excavation 4 us dollar per cubic m
Pile drilling 1000 mm dia 120$/m (with materail 300$)
anchor drilling or micro pile 27$/m (cost of anchor with materails around 850$ for 15 m length)
Berliner wall shoring down to 6 m max 150$/square (recoverable wall)
Grouting for base plug 320$/MC (with materail)
Hope the same is usefull

There are too many factors to reduce this to a formula.
Completly agree on low-price consultants. Too many projects sit on piles to bedrock 'cause the original geotechnical budget excluded appropriate soil strength and consolidation testing (or the engineer lacked experience).
f-d
