Why do you Need a Tire Wash?

Here are some reasons for a project designer to consider:

  1. You’re going to do earthwork in the wet season;
  2. Neighbors are watching what you are doing;
  3. Your project is controversial;
  4. You are cleaning up a contaminated site;
  5. You have a lot of truck and vehicle traffic driving through dirt and mud;
  6. Construction vehicles exit onto busy, public roads.

Check out the Western Region Climate Center website. I use this graph all of the time to show people the best time to do earthwork.

Embankment Fill Design

This is how we designed and constructed embankment fills for the 3rd Runway project 15 years ago. We sloped the benches and the top surface to drain water away from the face.

Low Impact Construction

Low Impact Development for Public Works Construction:
Erosion and Sediment Control Compliance

David S. Jenkins, Seattle, Washington

Introduction
Construction is a messy business; in the Puget Sound region of western Washington, with average annual rainfall of 40″ to 60″, it can also be challenging. Uncontrolled erosion from a construction site can generate 10-1000 times the quantity of sediment that occurs naturally from vegetated areas. Most construction in western Washington occurs near wetlands, streams, lakes, or the Puget Sound where sediment loss can reduce beneficial uses, or worse, destroy a salmon stream.

This paper will discuss proven methods that public works professionals can utilise to improve erosion control compliance and reduce project impacts.

Lessons in Solving Big Weather-Related Problems

When it comes to controlling erosion and sediment in bad weather, construction of a third runway at Seattle-Tacoma International Airport, near Seattle, WA, qualifies as a genuine challenge. Providing a foundation for the 8,500-ft.-long, 150-ft.-wide runway in the hilly terrain will require an estimated 17 million yd.3 of fill. Since construction began in 1997, about 5 million yd.3 have been placed. It will take a large fleet of dump trucks, running 20 hours a day, three and a half years to bring in the rest. Then there’s all that wet weather the area is famous for, especially in late fall and winter. Two years ago, for example, the project was drenched with about 5 in. of wind-driven rain in one 36-hour period. (more…)
