I am the earthwork supervisor for a middle sized residential builder. I am invloved in the job from concept through dedication. During the design phase of the job, I always review the plans from engineers prior to preliminary approval and once again prior to final approvals. When I check the...

Just wanted to provide some follow up to a previous thread located here: http://www.eng-tips.com/viewthread.cfm?qid=169526#postform Site work is complete using the approved benchmark adjustment and there were no issues with regard to utility tie-ins or making the grade work around the perimeter...

Good feedback... Thanks. Of course we did have the engineer look at the tie in points where roads and sewers meet existing and made the adjustments to the profiles. The entire job was raised so there would be no issues with driveway slopes because no driveways tie into existing roads. And as...

Hello to all! I just wanted to start up a conversation about benchmark adjustments. Does anyone have any experience with these at all? I am looking at constructing a final, approved set of plans where the site was found to be extremely heavy. To achieve a balance the site design grades would...

No compaction is done under the footing on virgin soil. No need to do that. In a structural fill situation, we compact under the guidance of a geotechnical engineer. The entire foundation pad gets rolled with a minimum 5 ton vibratory roller before footings are formed. OSHA standard overdigs...

You are right dozerman. I was trained to do it that way. That method is great for an excavating company, when you have to know the total amount of dirt moved for cost estimates, but I am a builder and am using Agtek to evaluate plans for total site balance. Additional pipe spoils can add upwards...

Just wanted to get some input as to the methods others use to estimate volumes of dirt from utility trenches. I am only interested in pipe spoils really, what is remaining after excavation and backfill. I am an Agtek User and find it I can't get a final volume using earthwork 3D. I can calc the...

I am looking to determine whether the stadard practice of not compacting backfill material around the foundation perimeter is a good practice when building in geologic areas containing Karst features. I am specifically conerned with water penetration and the possibility of sinkhole formation...

Hello! I'm a civil engineering technician and need to teach myself some of the basics of calulating lot pads. Can anyone point me in the direction of some resources or a quick tutorial on calculating lot pad elevations from site or lot plans? Or maybe you can drop a few tips for me in this...
