We prevented trackout by placing grizzlies from the road back into the site. Truck drivers backed up to the steel plate near the excavator and dumped their loads. The excavator operator moved the material into the proper piles. The truck tires came in clean, stayed clean on the grizzlies and left clean. With thought and planning, we didn’t need to install a tire wash.
This trackout was preventable. Asphalt was removed by the contractor to work on the new building foundation; the driveway asphalt was left in place, which is good. Gravel base course was delivered to be placed under the concrete slab.
Instead of backing all of the way into the site, over wet dirt, the trucks could have stayed on the asphalt driveway to unload. Site equipment could have been used to move the gravel.
The contractor could also have dumped gravel next to the asphalt, then graded it back into the site to provide a construction access into the site. In this way, the delivery truck could have stayed on gravel rather than driving on dirt.
While this is not a lot of dirt on the road, it does add up and is a magnet for inspectors and regulators to visit the site.
I encourage contractors to install curb and gutters to function as berms, as soon as possible. This contractor also installed the first lift of asphalt over gravel base course to provide a stable work surface. This provides a clean work surface and prevents sediment trackout. The projects shown are the SeaTac FAA Tracon facility and the SeaTac South Terminal Expansion Project.
