How many samples were taken for after compaction testing? Did they all fail? Were there hardness specifications for this material? If so, was testing done before placement? Was the source of the material on any kind of pre-approved list the owner may have? Did the supplier's proposal state...

Nunley: I'm with BeeJ. Anyone that passed 7th grade math can do an earthwork takeoff. It's a question of methodology and tolerance. I use Agtek now, but 30 years ago I used a mylar sheet with a 1" grid on it. Lay it over your grading plan, mark some reference points. Go to the center of each...

Can you build your fill in lifts reinforced with geotextiles? They'd be part of your permanent embankment, but you wouldn't have to try to yank out sheet pile, or leave piles/lagging in place

Thanks emm, I think that'll help.

Thanks CVG, I think that's helpful. M2, there's room for one wiseguy here and I'm it.

"Perched waters are not limited in lateral extent & can be recharged, maybe continually recharged" So there's no real difference beteen 'perched water' and 'ground water'? Thank you

Understand, but I'm looking for a 'textbook' definition. Particularly if it addresses extensiveness. Like if I provide a relief trench to an area that has some topographic relief and a year later it's still draining, is this beyond the meaning of 'perched water'? Thank you

I don't know about over trash but I've seen a layer of geogrid and a foot or two of crusher run heal some really miserable earth.

Gentlemen: I'm looking for a textbook definition of 'perched water'. Any help out there? Thanks in advance

My guess is that comparing 'land shaping' to 'grading' is about like comparing a hair stylist to a barber.

I'm with Dick, how much contaminated water does the city plan on generating?

Are there better solutions? Yes. My first suggestion would be to tell them to go home. Otherwise, anything you do will kill the grass and probably make a mess. You might check into putting down a layer of light weight non woven fabric. Staple it down.

I'm with cvg. Bring in enough road base/well graded gravel to put 2' cover over it and you're most likely fine.

Normally there's a capillary barrier of clean stone under a slab on grade, check your structural and architectural drawings. I'd be surprised if there's supposed to be anything under the footings unles you get into an unsuitable soil condition, but again check your structural details and notes.

If you've got a geotechnical report and a grading plan I'm sure you can get a local heavy/highway contractor to give you pricing.If the abutting properties are developed,any information available would be handy. Different areas have different requirements regarding proximity of blasting to...
