Landfill Mining: Current Trends

The beneficial purposes can include recovery of recyclable materials, recovery of soils for use as daily or intermediate cover in active landfills, or recovery of land area for redevelopment. As urban sprawl has continued in many metropolitan areas, landfills—which previously were located in areas relatively distant from the population centers—are

Taking the Measure of Methods for Estimating Earthwork Volumes

Taking the Measure of Methods for Estimating Earthwork Volumes

For earthwork contractors the key to survival is an accurate estimate of earthwork volumes. Without an accurate estimate of earthwork volumes, the contractor will be unable to properly assign construction assets or formulate a project schedule. Estimating earthwork construction requires many assumptions and unknowns.

Why We Do It

Why We Do It

Do you ever have trouble explaining to people what it is you do on the job, or why it’s important? You probably know about World Soil Day—it’s December 5, in case you didn’t—which is an effort to increase awareness of the importance of soils and the need for conservation efforts

Custom Site Challenges, Custom Solutions

Jeff Herndon, co-owner of Herndon Inc. in Lugoff, SC, knows that hilly terrain can mean that a relatively high volume of sediment collects in sedimentation barriers in a short time, necessitating short intervals between removals of sediment buildup. Maintaining intact barriers is one thing; having to clean up after a

Landfills, Maintenance, and Success

If there is one idea that a landfill operator has to keep in mind, it is the fact that maintenance and repair are two different things entirely. Maintenance is what is done to prevent having to perform repairs. Maintenance is performed at regular planned intervals. Repair is unscheduled and performed

Seattle Takes Natural Drainage to a High Point

Seattle Takes Natural Drainage to a High Point

Seattle’s Natural Drainage System (NDS) consists of stormwater management projects that use low-impact development (LID) strategies to meet multiple goals within street rights of way (ROWs), which account for 25% of Seattle’s total land surface. The projects work by infiltrating stormwater runoff, slowing it temporarily or lessening its volume, filtering,

Off the Level

The recipe, the ingredients and the tools needed to produce the finish product vary from site to site, taking into account degree of difficulty, locality and soil and rock conditions.
