When it comes to scheduling your work I think simpler is often better. Being able to place all your work on one calendar can allow you to see how all your work fits. Do I have enough people hired? Are all the jobs starting at one time? As a subcontractor you may be in less control of your work load. That doesn't mean you don't try to get a handle on it.

I was looking through the Iowa DOT website last week and ran across this field guide on erosion control. It was produced several years ago by the Iowa DOT Office of Construction. It is the best information I have ever seen on erosion control practices. Full of photos of dos and don'ts when installing erosion control. The guide can be downloaded here. You can order a hard copy for $8.00. Order form.
