Thanks for the info, and suggestions. What I am doing now, is research and data gathering. My goal is to stay out of reality and determine what we should have known. I can answer you number 4, since the hole is 1/2 done, blasted out and excavated, with a ramp. The blasters decided to do it...

Thanks for the suggestions. The company I work for is the blasting firm involved. We are a highway heavy contractor and blasting is one of the main aspects of the company. The plan was to drill line holes and presplit the face. What I'm trying to determine is if anything in the boring logs...

There are RQD %'s on the first boring the RQD %is all 100% and then one segment is 95%. On the second one they range from 72% to 100% with most being around the low 90's. The rock to be blasted and excavated is about a 500ft long, 100ft wide and 70ft deep hole. The owner wants cookie cutter...

The borings are from 2004 and 2005, the geotech or geologist was not able/willing to talk about borings that are so old.

Gain knowledge about how the rock will behave for blasting and excavation. Also gain and understanding of what they mean, or what the implications of fractures are in the boring data.

I was mistaken, there are 2 more borings into the rock, but by a different company. On theres they do not list discontinuities, but at various points on the boring they use descriptions like "(FRAC., low angle)" and "(FRAC., high angle)" I'm assuming this is the same discontinuities or similar...

So, I'm going over a bunch of data for a project, and some of it is 30 or so boring logs. 2 of the borings, go about 70 feet into granite. I'm not sure how to interpret a few comments, and some suggestions would be great. The note says this: " GRANITE Weathering: Generally fresh with some...

We use Agtek for volumes, and Heavy Bid for estimating, and Viewpoint for accounting, the combo works well, Viewpoint and Heavy Bid communicate for a nearly seamless interaction.

There is Conversion information out there depending on your material. It is common to convert from excavated volume, to lose volume, and to compacted Volume. The contractor I work for has data on a number of different materials, though they don't like to share since much of the info has come...
