I have a client interested in constructing a septage treatment facility that would include dewatering presses and pumping resultant liquid component about 180 feet (vertical head) up a hill to some leaching fields.
He has a great property for it except 3-phase does not come to his property, and...
I designed a fire pond that got built a couple years ago. During construction the contractor uncovered some fractured ledge that he believes is slowly draining the pond. He believes this is the one area that's draining as the water level was rising until he dredged out this particular area and...
Version 9, which I recently upgraded to, includes several CN values for impervious and unconnected impervious. A house out in the woods of a 2 or 5 acre (or however large)parcel that is sloped towards the woods seems a pretty straightforward candidate for using "roofs - unconnected impervious"...
I have a client, an existing summer camp, for whom we've just created an overall base map of all his buildings and utilities. I plan to give him a CAD file so he can update his map as he goes along. My question is whether anyone knows of inexpensive programs he can look into so he can edit the...
Has anyone had experience with using these products and how they compare? SiltSoxx shown on plans but contractor wants to use Earth Savers straw wattles due to cost difference. Also SiltSoxx needs a certified installer.
The site is right on the bank of a stream leading directly into a lake &...
When designing concrete sidewalks with curbing I've always preferred granite curbing (and being in the granite state it's available, but relatively expensive). Many contractors and owners prefer to just leave the concrete edge as "curbing" because it's so much cheaper. However, isn't it proper...
I'm curious how other engineers feel about what to include on roadway cross-sections (i.e. those sections shown for every 50' station).
When there are buried utilities - sewerlines, stormdrains, waterlines, etc. - do you show their location on every section? Or do you create sections only for...
I posted this in the NFPA discussion, but as it doesn't look real active I thought I'd post it here as well. It's somewhat of an urgent issue as the fire chiefs comments came through at the eleventh hour.
Can anyone help me out with what NFPA specifies as the distance needed between...
Can anyone help me out with what NFPA specifies as the distance needed between self-storage buildings? I spoke with the local fire chief before designing a project and we talked about 20-25' needed for aisle width between the buildings, so we used 25'. He has now come back and said the new...
I'm designing a small subdivision where there will clearly be a need to blast several locations for road and house construction. Off the top of my head, I would expect the most depth from ground surface to be removed will be about 8 feet. That would be for some of the house foundations. The...
Is there any consensus as to what type of pipe might be better for service lines between a ductile iron water main and structures the main serves?
My particular case is a new main serving a half dozen residential care buildings (small, 5-20 resident children and staff per building). I'm going...
I'm getting involved with a new kennel operation for 80 dogs and, as concerns are being raised by the city zoning board about groundwater/well contamination from dog urine, am gathering info on this subject.
Solid waste in the yard will be picked up throughout the day and will be removed...
Yet another wet basement....
My basic question here is this -- has anyone had success with sealant products inside a structure? In this case, a garage and basement.
Here is the problem:
A house has been built, about six years ago, into a steep hillside with a high water table. A garage is...
Do people have a standard preference for using either standard proctor or modified proctor for checking compaction along waterlines? I've been doing some inspections where the spec's in the waterline detail call out for compacting to 95% modified proctor yet the state DOT and town highway dept...
