Skiers and children on sleds love a slope on a snowy day, while grounds keepers dread the slopes in mowing season. Slopes are part of our landscape, and we need to deal with them. This applies to the design of a culvert installation as well, particularly when the slope is going across the culvert side-to-side, as opposed to being along the length

After having successfully completed a new professional development hour (PDH) article for Informed Infrastructure on the topic of buried culverts and service life, I was struck by the complexity of what may seem, at first blush, to be a relatively straightforward project. Specifically – the importance of the backfill material selection process.Not

Dear Tech Abby:  Do I have to use a crushed stone backfill for my PVC sewer pipe installation?  --That 70’s EngineerDear That 70’s Engineer:  Good question… the answer is “maybe”…Well, let me expand on that.  First, when talking about PVC sewer pipe, remember that PVC products are commonly used in both gravity flow sanitary and storm sewer

Resistivity has to be one of my top ten favorite words used in the engineering community, and today I would like to dive a little deeper into how important this factor is in the longevity and durability of a pipe’s life cycle – hence the reciprocity or  “give back” of resistivity.I was thinking about the questions I often have to field with regard

The focus on environmental issues and “green construction” techniques is readily apparent in today’s construction marketplace. The U.S. Green Building Council and their Leadership in Energy and Environmental Design (LEED) Green Building Rating System for New Construction program places the emphasis on use of environmentally friendly construction
