Load DissipationAs promised, here is the second part of this two-part blog series. In the first section, I discussed the standard live load design vehicles and presented the design methodology of these vehicles. In the second part of this series, I will discuss how the live load dissipates, and how to determine the live load pressure at various

For this two-part series, we’re going to delve into live loading. A majority of what will be covered in this article goes into design methodology. Additional detail will be included in the follow up, so make sure to check back for that second article. Standard design live load vehicles on corrugated pipe can be mostly broken down into the following

After recently completing a PDH article for Informed Infrastructure entitled, ""How to Design a Culvert Reline Project." I thought it apropos that we take some time here to answer a few more questions regarding reline that I have received over the course of time. So without further ado and in no particular order, let's delve into the World of

Hello all… how about a quick blog on PVC pipe and UV protection? I am often asked about the effects of UV exposure caused by sunlight on PVC sewer pipes and how to provide protection. Many people in the civil engineering industry have concerns with UV exposure and polymeric-based sewer materials (e.g. thermoplastic, PVC, HDPE, other plastic pipe)

Reclaim TunnelsA Reclaim Tunnel refers to a buried conduit that encloses a material conveyor. The conduit is used to transport aggregate, sand, coal or other minerals from a central stock pile to an off loading location. These material stock piles can be as tall as 80’ high. Reclaim Tunnels will normally have hopper openings to allow flow of the
